Significance: The irregular response to PARPi in HRD-positive and -negative tumors highlights the need for identifying additional biomarkers. This study explores the mutational landscape beyond HRD status in AOC, ultimately advancing precision oncology in future clinical practice., (©2024 The Authors; Published by the American Association for Cancer Research.)

Aim: We report clinical activity and safety of sitravatinib in patients with advanced cancer from basket cohorts with specific molecular alterations, in a Phase Ib study. Materials & methods: Patients with advanced solid tumors harboring amplification, mutation, or rearrangement of MET , AXL , RET , NTRK , DDR2 , KDR , PDGFRA , KIT or CBL received sitravatinib once daily. Primary end point was confirmed objective response rate (ORR). Results: In total, 113 patients were enrolled following a median of 3 (range 1-18) prior systemic regimens. Altered RET (n = 31), CBL (n = 31) and MET (n = 17) were most frequent cohorts. Overall, 68.9% had reduced tumor volume and most (61.5%) had a best objective response of stable disease. ORR was highest in patients with RET -rearranged non-small cell lung cancer (21.1%) but did not differ significantly from the null hypothesis (ORR ≤15%; p = 0.316). Median progression-free survival and overall survival (5.7 and 24.2 months, respectively) were also longest in the RET -rearranged non-small cell lung cancer cohort. Diarrhea (61.1%), fatigue (50.4%) and hypertension (46.9%) were the most frequent treatment-emergent adverse events. Most treatment-emergent adverse events were mild-to-moderate in severity. The study closed before the planned number of patients were enrolled in all cohorts. Conclusion: Sitravatinib had a manageable safety profile with modest signals of clinical activity in patients with molecularly selected solid tumors.Clinical trial registration: www.clinicaltrials.gov identifier is NCT02219711.

The NCCN Guidelines for Ovarian Cancer/Fallopian Tube Cancer/Primary Peritoneal Cancer provide multidisciplinary diagnostic workup, staging, and treatment recommendations for this disease. These NCCN Guidelines Insights detail how the evolution of the use of PARP inhibitors as maintenance and single-agent regimens for the treatment of ovarian cancer informed panel recommendations in the guidelines.

Sitravatinib (MGCD516) is an oral inhibitor of several closely related oncogenic tyrosine kinase receptors that include VEGFR-2 (vascular endothelial growth factor receptor-2), AXL, and MET (mesenchymal-epithelial transition). The safety and antitumor activity of sitravatinib are reported in patients from two histologic cohorts (anti-angiogenesis-refractory clear cell renal cell carcinoma [RCC] and castrate-resistant prostate cancer [CRPC] with bone metastases) who participated in a Phase 1/1b study. The patients were enrolled using a 3-stage design that was based on observed objective responses. Objective response rate (ORR) was the primary endpoint. Duration of response, progression-free survival (PFS), overall survival (OS), and safety were also assessed. Overall, 48 patients (RCC n = 38, CRPC n = 10) received ≥ 1 dose of sitravatinib. Both cohorts were heavily pretreated (median number of prior systemic therapies: RCC cohort 3, CRPC cohort 6). In the RCC cohort, ORR was 25.9%, P = 0.015 (null hypothesis [ORR ≤ 10%] was rejected). Responses were durable (median duration 13.2 months). Median PFS was 9.5 months and median OS was 30.0 months. No objective responses were seen in the CRPC cohort; median PFS and OS were 5.8 months and 10.1 months, respectively. Across both cohorts, diarrhea (72.9%), fatigue (54.2%), and hypertension (52.1%) were the most frequent all-cause treatment-emergent adverse events (TEAEs). Diarrhea and vomiting (both, 6.3%) were the most frequent serious TEAEs considered related to study treatment. Sitravatinib demonstrated an acceptable safety profile and promising clinical activity in patients with clear cell RCC refractory to prior angiogenesis inhibitor therapy. Strong indicators for clinical activity were not seen in patients with CRPC and bone metastases. Clinical trial registration:ClinicalTrials.gov NCT02219711., Competing Interests: Declarations.

Purpose: This study aimed to report the results from an early-phase study of rivoceranib, an oral tyrosine kinase inhibitor highly selective for vascular endothelial growth factor receptor 2, in patients with advanced solid tumors., Materials and Methods: In this open-label, single-arm, dose-escalating, multicenter three-part phase 1/2a trial, patients had advanced solid tumors refractory to conventional therapy. Part 1 evaluated the safety and pharmacokinetics of five ascending once-daily doses of rivoceranib from 81 mg to 685 mg. Part 2 evaluated the safety and antitumor activity of once-daily rivoceranib 685 mg. Part 3 was conducted later, due to lack of maximum tolerated dose determination in part 1, to evaluate the safety and preliminary efficacy of once-daily rivoceranib 805 mg in patients with unresectable or advanced gastric cancer., Results: A total of 61 patients were enrolled in parts 1 (n=25), 2 (n=30), and 3 (n=6). In parts 1 and 2, patients were white (45.5%) or Asian (54.5%), and 65.6% were male. The most common grade ≥ 3 adverse events were hypertension (32.7%), hyponatremia (10.9%), and hypophosphatemia (10.9%). The objective response rate (ORR) was 15.2%. In part 3, dose-limiting toxicities occurred in two out of six patients: grade 3 febrile neutropenia decreased appetite, and fatigue. The ORR was 33%., Conclusion: The recommended phase 2 dose of rivoceranib was determined to be 685 mg once daily, which showed adequate efficacy with a manageable safety profile (NCT01497704 and NCT02711969).

Purpose: Complementary and alternative medicine (CAM) use during cancer treatment is controversial. We aim to evaluate contemporary CAM use, patient perceptions and attitudes, and trust in various sources of information regarding CAM., Methods: A multi-institutional questionnaire was distributed to patients receiving cancer treatment. Collected information included respondents' clinical and demographic characteristics, rates of CAM exposure/use, information sources regarding CAM, and trust in each information source. Comparisons between CAM users and nonusers were performed with chi-squared tests and one-way analysis of variance. Multivariable logistic regression models for trust in physician and nonphysician sources of information regarding CAM were evaluated., Results: Among 749 respondents, the most common goals of CAM use were management of symptoms (42.2%) and treatment of cancer (30.4%). Most CAM users learned of CAM from nonphysician sources. Of CAM users, 27% reported not discussing CAM with their treating oncologists. Overall trust in physicians was high in both CAM users and nonusers. The only predictor of trust in physician sources of information was income >$100,000 in US dollars per year. Likelihood of trust in nonphysician sources of information was higher in females and lower in those with graduate degrees., Conclusion: A large proportion of patients with cancer are using CAM, some with the goal of treating their cancer. Although patients are primarily exposed to CAM through nonphysician sources of information, trust in physicians remains high. More research is needed to improve patient-clinician communication regarding CAM use.

Background: Oncology clinical trials are complex, and the COVID-19 pandemic caused major disruptions in 2020., Methods: Using its networking and sharing of best practices, the Association of American Cancer Institutes, comprising 105 cancer centers, solicited a longitudinal series of voluntary surveys from members to assess how clinical trial office operations were affected. The surveys showed that centers were able to keep oncology trials available to patients while maintaining safety. Data were collected regarding interventional clinical trial accruals for the calendar years 2019, 2020, and 2021., Results: Data demonstrated a sizeable decrease in interventional treatment trial accruals in both 2020 and 2021 compared with prepandemic figures in 2019. No cancer center reported an increase in interventional treatment trial accruals in 2020 compared with 2019, with most centers reporting a moderate decrease. In mid-2022, 15% of respondents reported an increasing trend, 31% reported no significant change, and 54% continued to report a decrease., Conclusions: The pandemic necessitated rapid adoption of trial operations, with the emergence of several best practices, including remote monitoring, remote consenting, electronic research charts, and work-from-home strategies for staff. The national infrastructure to conduct trials was significantly affected by the pandemic, with noteworthy resiliency, evidenced by improvements in efficiencies and patient-centered care delivery but with residual capacity challenges that will be evident for the foreseeable future., (© The Author(s) 2023.

Epithelial ovarian cancer is the leading cause of death from gynecologic cancer in the United States, with less than half of patients living >5 years following diagnosis. The NCCN Guidelines for Ovarian Cancer provide recommendations for the diagnosis, evaluation, treatment, and follow-up for patients with ovarian, fallopian tube, and primary peritoneal cancers. These NCCN Guidelines Insights summarize the panel discussion behind recent important updates to the guidelines, including revised guidance on alternative chemotherapy regimens for patients with advanced age and/or comorbidities, a new algorithm for recurrent low-grade serous carcinoma based on developing research and novel therapeutic agents, and updated language regarding tumor molecular analysis applications in ovarian cancer.

BERENICE (NCT02132949) assessed the cardiac safety of the neoadjuvant−adjuvant pertuzumab−trastuzumab-based therapy for high-risk, HER2-positive early breast cancer (EBC). We describe key secondary objectives at final analysis. Eligible patients received dose-dense doxorubicin and cyclophosphamide q2w × 4 ➝ paclitaxel qw × 12 (Cohort A) or 5-fluorouracil, epirubicin, cyclophosphamide q3w × 4 ➝ docetaxel q3w × 4 (B) as per physician’s choice. Pertuzumab−trastuzumab (q3w) was initiated from the taxane start and continued post-surgery to complete 1 year. Median follow-up: 64.5 months. There were no new cardiac issues and a low incidence of Class III/IV heart failure (Cohort B only: one patient (0.5%) in the adjuvant and treatment-free follow-up (TFFU) periods). Fourteen patients (7.7%) had LVEF declines of ≥10% points from baseline to <50% in Cohort A, as did 20 (10.5%) in B during the adjuvant period (12 (6.2%) in A and 7 (3.6%) in B during TFFU). The five-year event-free survival rates in Cohorts A and B were 90.8% (95% CI: 86.5, 95.2) and 89.2% (84.8, 93.6), respectively. The five-year overall survival rates were 96.1% (95% CI: 93.3, 98.9) and 93.8% (90.3, 97.2), respectively. The final analysis of BERENICE further supports pertuzumab−trastuzumab-based therapies as standard of care for high-risk, HER2-positive EBC.

Background: Combining immunotherapy and antiangiogenic agents is a promising treatment strategy in endometrial cancer. To date, no biomarkers for response have been identified and data on post-immunotherapy progression are lacking. We explored the combination of a checkpoint inhibitor (nivolumab) and an antiangiogenic agent (cabozantinib) in immunotherapy-naïve endometrial cancer and in patients whose disease progressed on previous immunotherapy with baseline biopsy for immune profiling., Patients and Methods: In this phase II trial (ClinicalTrials.gov NCT03367741, registered December 11, 2017), women with recurrent endometrial cancer were randomized 2:1 to nivolumab with cabozantinib (Arm A) or nivolumab alone (Arm B). The primary endpoint was Response Evaluation Criteria in Solid Tumors-defined progression-free survival (PFS). Patients with carcinosarcoma or prior immune checkpoint inhibitor received combination treatment (Arm C). Baseline biopsy and serial peripheral blood mononuclear cell (PBMC) samples were analyzed and associations between patient outcome and immune data from cytometry by time of flight (CyTOF) and PBMCs were explored., Results: Median PFS was 5.3 (90% CI 3.5 to 9.2) months in Arm A (n=36) and 1.9 (90% CI 1.6 to 3.4) months in Arm B (n=18) (HR=0.59, 90% CI 0.35 to 0.98; log-rank p=0.09, meeting the prespecified statistical significance criteria). The most common treatment-related adverse events in Arm A were diarrhea (50%) and elevated liver enzymes (aspartate aminotransferase 47%, alanine aminotransferase 42%). In-depth baseline CyTOF analysis across treatment arms (n=40) identified 35 immune-cell subsets. Among immunotherapy-pretreated patients in Arm C, non-progressors had significantly higher proportions of activated tissue-resident (CD103+CD69+) ɣδ T cells than progressors (adjusted p=0.009)., Conclusions: Adding cabozantinib to nivolumab significantly improved outcomes in heavily pretreated endometrial cancer. A subgroup of immunotherapy-pretreated patients identified by baseline immune profile and potentially benefiting from combination with antiangiogenics requires further investigation., Competing Interests: Competing interests: SL has received honoraria from AstraZeneca, Merck, Eisai, GSK, and Roche.

Objective: To investigate the trends of 1-year mortality and neonatal morbidities in preterm infants with serious congenital heart disease (CHD)., Study Design: This cohort study used a population-based administrative dataset of all liveborn infants of 26-36 weeks gestational age with serious CHD born in California between 2011 and 2017. We assessed 1-year mortality and major neonatal morbidities (ie, retinopathy of prematurity, bronchopulmonary dysplasia, necrotizing enterocolitis, intraventricular hemorrhage grade >2, and periventricular leukomalacia) across the study period and compared these outcomes with those in infants without CHD., Results: We identified 1921 preterm infants with serious CHD. The relative risk (RR) of death decreased by 10.6% for each year of the study period (RR, 0.89; 95% CI, 0.84-0.95), and the RR of major neonatal morbidity increased by 8.3% for each year (RR, 1.08; 95% CI, 1.02-1.15). Compared with preterm neonates without any CHD (n = 234 522), the adjusted risk difference (ARD) for mortality was highest at 32 weeks of gestational age (9.7%; 95% CI, 8.3%-11.2%), that for major neonatal morbidity was highest at 28 weeks (21.9%; 95% CI, 17.0%-26.9%), and that for the combined outcome was highest at 30 weeks (26.7%; 95% CI, 23.3%-30.1%)., Conclusions: Mortality in preterm neonates with serious CHD decreased over the last decade, whereas major neonatal morbidities increased. Preterm infants with a gestational age of 28-32 weeks have the highest mortality or morbidity compared with their peers without CHD. These results support the need for specialized and focused medical neonatal care in preterm neonates with serious CHD., (Copyright © 2021 Elsevier Inc. All rights reserved.)

Background: Disulfiram and metals inactivate key oncoproteins resulting in anti-neoplastic activity. The goal of this study was to determine the maximum tolerated dose of copper when administered with disulfiram in patients with advanced solid tumors and liver involvement., Methods: Disulfiram 250 mg was administered daily in 28-day cycles. Four doses of copper gluconate were tested (2, 4, 6, and 8 mg of elemental copper) in a standard 3 + 3 dose escalation design. Patients were evaluated for dose limiting toxicities and response. Protein S-glutathionylation was evaluated as a pharmacodynamic marker., Results: Twenty-one patients were enrolled and 16 patients were evaluable for dose limiting toxicities. Among the 21 patients, there was a median of 4 lines of prior chemotherapy. Five Grade 3 toxicities were observed (anorexia, elevated aspartate aminotransferase or AST, elevated alkaline phosphatase, fever, and fatigue). Response data was available for 15 patients. Four patients had stable disease with the longest duration of disease control being 116 days. The median duration of treatment for evaluable patients was 55 days (range 28-124). Reasons for discontinuation included functional decline, disease progression, and disease-associated death. Increased S-glutathionylation of serum proteins was observed with treatment., Conclusion: Disulfiram 250 mg daily with copper gluconate (8 mg of elemental copper) was well-tolerated in patients with solid tumors involving the liver and was not associated with dose limiting toxicities. While temporary disease stabilization was noted in some patients, no objective responses were observed. Treatment was associated with an increase in S-glutathionylation suggesting that this combination could exert a suppressive effect on cellular growth and protein function., Trial Registration: NCT00742911 , first posted 28/08/2008.

Epithelial ovarian cancer is the leading cause of death from gynecologic cancer in the United States and is the country's fifth most common cause of cancer mortality in women. A major challenge in treating ovarian cancer is that most patients have advanced disease at initial diagnosis. These NCCN Guidelines discuss cancers originating in the ovary, fallopian tube, or peritoneum, as these are all managed in a similar manner. Most of the recommendations are based on data from patients with the most common subtypes─high-grade serous and grade 2/3 endometrioid. The NCCN Guidelines also include recommendations specifically for patients with less common ovarian cancers, which in the guidelines include the following: carcinosarcoma, clear cell carcinoma, mucinous carcinoma, low-grade serous, grade 1 endometrioid, borderline epithelial, malignant sex cord-stromal, and malignant germ cell tumors. This manuscript focuses on certain aspects of primary treatment, including primary surgery, adjuvant therapy, and maintenance therapy options (including PARP inhibitors) after completion of first-line chemotherapy.

Purpose: Cancer clinical trials offices (CTOs) support the investigation of cancer prevention, early detection, and treatment at cancer centers across North America. CTOs are a centralized resource for clinical trial conduct and typically use research staff with expertise in four functional areas of clinical research: finance, regulatory, clinical, and data operations. To our knowledge, there are no publicly available benchmark data sets that characterize the size, cost, volume, and efficiency of these offices, nor whether the metrics differ by National Cancer Institute (NCI) designation. The Association of American Cancer Institutes (AACI) Clinical Research Innovation (CRI) steering committee developed a survey to address this knowledge gap., Methods: An 11-question survey that addressed CTO budget, accrual and trial volume, full-time equivalents (FTEs), staff turnover, and activation timelines was developed by the AACI CRI steering committee and sent to 92 academic cancer research centers in North America (n = 90 in the United States; n = 2 in Canada), with 79 respondents completing the survey (86% completion rate)., Results: The number of FTE employees working in the CTOs ranged from 4.5 to 811 (median, 104). The median number of analytic cases (ie, newly diagnosed or received first course of treatment) reported by the main center was 3,856. Annual CTO budgets ranged from $250,000 to $23,900,000 (median, $8.2 million). The median trial activation time, based on 61 centers, was 167 days. The median number of accruals per center was 480 (range, 5-6,271) and median number of trials per center was 282 (range, 31-1,833). Budget and FTE ranges varied by NCI designation., Conclusion: The response rate to the survey was high. These data will allow cancer centers to evaluate their CTO infrastructure, funding, portfolio, and/or accrual goals as compared with peers. A wide range in each of the outcomes was noted, in keeping with the wide variation in size and scope of cancer center CTOs across the United States and Canada. These variations may warrant additional investigation.

Purpose: This study aimed to determine the safety, tolerability, and recommended phase II doses of trametinib plus uprosertib (GSK2141795) in patients with solid tumors likely to be sensitive to MEK and/or AKT inhibition., Methods: This was a phase I, open-label, dose-escalation, and dose-expansion study in patients with triple-negative breast cancer or BRAF-wild type advanced melanoma. The primary outcome of the expansion study was investigator-assessed response. Among 126 enrolled patients, 63 received continuous oral daily dosing of trametinib and uprosertib, 29 received various alternative dosing schedules, and 34 were enrolled into expansion cohorts. Doses tested in the expansion cohort were trametinib 1.5 mg once daily (QD) + uprosertib 50 mg QD., Results: Adverse events (AEs) were consistent with those reported in monotherapy studies but occurred at lower doses and with greater severity. Diarrhea was the most common dose-limiting toxicity; diarrhea and rash were particularly difficult to tolerate. Overall, 59% and 6% of patients reported AEs with a maximum severity of grade 3 and 4, respectively. Poor tolerability prevented adequate delivery of uprosertib with trametinib at a concentration predicted to have clinical activity. The study was terminated early based on futility in the continuous-dosing expansion cohorts and a lack of pharmacological or therapeutic advantage with intermittent dosing. The objective response rate was < 5% (1 complete response, 5 partial responses)., Conclusions: Continuous and intermittent dosing of trametinib in combination with uprosertib was not tolerated, and minimal clinical activity was observed in all schedules tested.

Early endometrial cancer has an overall survival of greater than 80% (1). One of the poor prognostic factors that may be associated with the 20% who do not survive 5 years is the presence of lymphovascular space invasion (LVSI). LVSI is associated with increased nodal metastasis and decreased progression free survival (PFS) and overall survival (OS). (2-8). Therefore, unstaged, LVSI positive early endometrial cancer requires additional management with either completion of staging with lymphadenectomy or adjuvant radiation. We focus on reviewing the management of natural history and management of early endometrial cancer followed by the prognostic impact of LVSI, management options and recommendations., (Copyright © 2019 Elsevier Inc.

Objective: The 2018 International Federation of Gynecology and Obstetrics (FIGO) staging system for cervical cancer changed from a clinical system to a clinical/pathologic/radiologic system with stages IIIC1 and IIIC2 indicating positive pelvic and para-aortic lymph nodes, respectively. We evaluated the National Cancer Database (NCDB) for the impact on survival of lymph node metastases (LNM)., Methods: The NCDB from 2004 to 2015 was queried for patients with cervical cancer, yielding 115,819 patients. Patients with FIGO IVB (22,569), non-adeno/squamous cell histologies (5,909), unknown nodal status (60,695), or unknown survival time (9,473) were excluded. Survival was compared using Cox proportional hazard model based on nodal status. Univariate (UVA) and multivariate analyses (MVA) were done for the overall cohort, followed by UVA by individual stage., Results: In 17,173 eligible patients, LNM negatively affected survival (UVA IIIC1 Hazard Ratio [HR] 2.0, p < 0.001, IIIC2 HR 3.9, p < 0.001, MVA IIIC1 HR 1.36, p < 0.001, IIIC2 HR 2.14, p < 0.001). In T1B, the effect of IIIC2 was most pronounced (HR 5.38, p < 0.001 versus HR 1.5 p = 0.001 for IIIC1 disease). In T3, the effect of LNM was markedly less: (HR 1.7, p < 0.001 for IIIC2 versus HR 1.2 p = 0.02 for IIIC1). Within T1B, there was no difference in survival for IIIC1 for the smaller T stages (IB1-2)., Conclusion: In this study, LNM negatively affects prognosis in cervical cancer. The impact on survival varies by T stage with the greatest effect seen in stage T1B with IIIC2 disease., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Background: Data are limited regarding the use of poly(adenosine diphosphate [ADP]-ribose) polymerase inhibitors, such as veliparib, in combination with chemotherapy followed by maintenance as initial treatment in patients with high-grade serous ovarian carcinoma., Methods: In an international, phase 3, placebo-controlled trial, we assessed the efficacy of veliparib added to first-line induction chemotherapy with carboplatin and paclitaxel and continued as maintenance monotherapy in patients with previously untreated stage III or IV high-grade serous ovarian carcinoma. Patients were randomly assigned in a 1:1:1 ratio to receive chemotherapy plus placebo followed by placebo maintenance (control), chemotherapy plus veliparib followed by placebo maintenance (veliparib combination only), or chemotherapy plus veliparib followed by veliparib maintenance (veliparib throughout). Cytoreductive surgery could be performed before initiation or after 3 cycles of trial treatment. Combination chemotherapy was 6 cycles, and maintenance therapy was 30 additional cycles. The primary end point was investigator-assessed progression-free survival in the veliparib-throughout group as compared with the control group, analyzed sequentially in the BRCA -mutation cohort, the cohort with homologous-recombination deficiency (HRD) (which included the BRCA -mutation cohort), and the intention-to-treat population., Results: A total of 1140 patients underwent randomization. In the BRCA -mutation cohort, the median progression-free survival was 34.7 months in the veliparib-throughout group and 22.0 months in the control group (hazard ratio for progression or death, 0.44; 95% confidence interval [CI], 0.28 to 0.68; P<0.001); in the HRD cohort, it was 31.9 months and 20.5 months, respectively (hazard ratio, 0.57; 95 CI, 0.43 to 0.76; P<0.001); and in the intention-to-treat population, it was 23.5 months and 17.3 months (hazard ratio, 0.68; 95% CI, 0.56 to 0.83; P<0.001). Veliparib led to a higher incidence of anemia and thrombocytopenia when combined with chemotherapy as well as of nausea and fatigue overall., Conclusions: Across all trial populations, a regimen of carboplatin, paclitaxel, and veliparib induction therapy followed by veliparib maintenance therapy led to significantly longer progression-free survival than carboplatin plus paclitaxel induction therapy alone. The independent value of adding veliparib during induction therapy without veliparib maintenance was less clear.

Objectives: In endometrial cancer, the appropriate sequence of adjuvant chemotherapy (aCT) and adjuvant radiation therapy (aRT) is unclear. We aim evaluated whether early chemotherapy is associated with improved overall survival (OS) and cancer-specific survival (CSS)., Methods: Endometrial cancer patients that received aCT and aRT were selected from the SEER-Medicare database. Early chemotherapy was defined as receiving aCT before aRT, with or without additional aCT ("sandwich" regimens). All other patients received a full course of aRT before chemotherapy with or without concurrent chemotherapy. Univariate and multivariate Cox proportional hazards regression was utilized to assess the impact of clinical and demographic factors on OS., Results: We selected 597 patients for analysis. Median age and was 72 years; 85% of patients were white. Overall, 68% of women had FIGO (International Federation of Gynecology and Obstetrics) stage III disease and 77% received 4 to 6 cycles of chemotherapy. Five-year OS (66.6% vs. 62.4%, P=0.46) and 5-year CSS (71.1% vs. 71.2%, P=0.88) was not significantly improved among those receiving early chemotherapy. In addition, early chemotherapy did not improve OS (hazard ratio [HR]=0.87; 95% confidence interval [CI]: 0.56-1.34, P=0.53) or CSS (HR=1.21; 95% CI: 0.82-1.79, P=0.34) on multivariate analysis. Compared with 1 to 3 cycles, receiving 4 to 6 (HR=0.48, 95% CI: 0.26-0.87, P=0.02), and ≥7 cycles (HR=0.42, 95% CI: 0.20-0.89, P=0.02) of chemotherapy was associated with improved OS., Conclusion: No differences in OS or CSS were noted among endometrial patients receiving early chemotherapy. However, the number of chemotherapy cycles was associated with prolonged survival.

Background: Platinum-based chemotherapy is the foundation of treatment for platinum-sensitive recurrent ovarian cancer, but has substantial toxicity. Bevacizumab and maintenance poly(ADP-ribose) polymerase (PARP) inhibitors both significantly improve efficacy versus standard therapy, primarily in terms of progression-free survival, and offer the potential for chemotherapy-free treatment. AVANOVA2 compared niraparib and bevacizumab versus niraparib alone as definitive treatment for platinum-sensitive recurrent ovarian cancer., Methods: This open-label, randomised, phase 2, superiority trial in 15 university hospitals in Denmark, Sweden, Finland, Norway, and the USA enrolled women aged 18 years or older with measurable or evaluable high-grade serous or endometrioid platinum-sensitive recurrent ovarian cancer. Patients had to have an Eastern Cooperative Oncology Group performance status of 0-2, and had to have previously received platinum-containing therapy for primary disease but ≤1 prior non-platinum-containing regimen for recurrent disease. Previous treatment with bevacizumab or first-line maintenance PARP inhibitors was permitted. Eligible patients were randomly assigned 1:1 (by random permuted blocks with block sizes of two and four, no masking), stratified by homologous recombination deficiency status and chemotherapy-free interval, to receive once-daily oral niraparib 300 mg alone or with intravenous bevacizumab 15 mg/kg once every 3 weeks until disease progression. The primary endpoint was progression-free survival, assessed by the investigators in the intention-to-treat population after events in at least 62 patients. Safety was analysed in all patients who received at least one dose of study drug. This ongoing trial is registered with ClinicalTrials.gov, number NCT02354131., Findings: Between May 23, 2016, and March 6, 2017, 97 patients were enrolled and randomly assigned: 48 to niraparib plus bevacizumab and 49 to single-agent niraparib. Median follow-up was 16·9 months (IQR 15·4-20·9). Niraparib plus bevacizumab significantly improved progression-free survival compared with niraparib alone (median progression-free survival 11·9 months [95% CI 8·5-16·7] vs 5·5 months [3·8-6·3], respectively; adjusted hazard ratio [HR] 0·35 [95% CI 0·21-0·57], p<0·0001). Grade 3 or worse adverse events occurred in 31 (65%) of 48 patients who received niraparib plus bevacizumab and 22 (45%) of 49 who received single-agent niraparib. The most common grade 3 or worse adverse events in both groups were anaemia (7 [15%] of 48 vs 9 [18%] of 49) and thrombocytopenia (5 [10%] vs 6 [12%]), and hypertension in the combination group (10 [21%] vs 0). Niraparib plus bevacizumab was associated with increased incidences of any-grade proteinuria (10 [21%] of 48 patients vs 0) and hypertension (27 [56%] of 48 vs 11 [22%] of 49) compared with niraparib alone. No treatment-related deaths occurred., Interpretation: The efficacy observed with this chemotherapy-free combination of approved agents in women with platinum-sensitive recurrent ovarian cancer warrants further evaluation. A randomised phase 3 trial investigating niraparib plus bevacizumab versus chemotherapy plus bevacizumab in platinum-sensitive recurrent ovarian cancer is planned., Funding: Nordic Society of Gynaecological Oncology and Tesaro., (Copyright © 2019 Elsevier Ltd.

PF-06647263, a novel antibody-drug conjugate consisting of an anti-EFNA4 antibody linked to a calicheamicin payload, has shown potent antitumor activity in human xenograft tumor models, including triple-negative breast cancer (TNBC). In the dose-escalation part 1 of this multicenter, open-label, phase I study (NCT02078752), successive cohorts of patients (n, 48) with advanced solid tumors and no available standard therapy received PF-06647263 every 3 weeks (Q3W) or every week (QW), following a modified toxicity probability interval (mTPI) method (initial dosing: 0.015 mg/kg Q3W). Primary objective in part 1 was to estimate the maximum tolerated dose (MTD) and select the recommended phase 2 dose (RP2D). In part 2 (dose-expansion cohort), 12 patients with pretreated, metastatic TNBC received PF-06647263 at the RP2D to further evaluate tumor response and overall safety. PF-06647263 QW administration (n, 23) was better tolerated than the Q3W regimen (n, 25) with only 1 DLT reported (thrombocytopenia). The most common AEs with the QW regimen (fatigue, nausea, vomiting, mucosal inflammation, thrombocytopenia, and diarrhea) were mostly mild to moderate in severity. The MTD was not estimated. PF-06647263 exposures increased in a dose-related manner across the doses evaluated. The RP2D was determined to be 0.015 mg/kg QW. Six (10%) patients achieved a confirmed partial response and 22 (36.7%) patients had stable disease. No correlations were observed between tumor responses and EFNA4 expression levels. Study findings showed manageable safety and favorable PK for PF-06647263 administered QW at the RP2D, with preliminary evidence of limited antitumor activity in patients with TNBC and ovarian cancer., (© 2019 UICC.)

Epithelial ovarian cancer is the leading cause of death from gynecologic cancer in the United States, with less than half of patients living >5 years from diagnosis. A major challenge in treating ovarian cancer is that most patients have advanced disease at initial diagnosis. The best outcomes are observed in patients whose primary treatment includes complete resection of all visible disease plus combination platinum-based chemotherapy. Research efforts are focused on primary neoadjuvant treatments that may improve resectability, as well as systemic therapies providing improved long-term survival. These NCCN Guidelines Insights focus on recent updates to neoadjuvant chemotherapy recommendations, including the addition of hyperthermic intraperitoneal chemotherapy, and the role of PARP inhibitors and bevacizumab as maintenance therapy options in select patients who have completed primary chemotherapy.

Background: Endometrial cancer is the second most common cancer among female cancer survivors in the US and is increasing in incidence. Rural endometrial cancer patients experience lower survival rates but the reasons for the lower survival are not known. The aim of this study is to examine whether prognostic factors are different for rural and urban patients in a population-based cohort., Methods: Endometrial cancer patients diagnosed 1997-2012 were identified through the Utah Cancer Registry and Utah Population Database. The address at cancer diagnosis was used to classify patients in rural or urban residences. Demographic and cancer-specific characteristics were examined as prognostic factors for both all-cause and endometrial cancer-specific mortality using Cox proportional hazards models., Results: There were 2,994 endometrial cancer patients and 14.1% of these patients lived in rural areas at diagnosis. Rural endometrial cancer patients were older at cancer diagnosis and did not appear to be different in terms of obesity or overweight at cancer diagnosis. There were no differences for treatment or stage at diagnosis although rural patients had higher proportions of higher grade. Age at diagnosis, poverty, education, and histology were significant prognostic factors for all-cause death. Rural patients with more advanced stages of cancer had significantly increased risks of all-cause and endometrial cancer-specific death than urban patients. Rural endometrial cancer patients diagnosed at advanced stage had a 17-fold increase in the risk of all-cause death compared to an 8-fold increase in death for urban patients., Conclusions: Rural endometrial cancer patients in Utah were older at diagnosis, had higher grade and higher comorbidities. While urban and rural endometrial cancer patients shared many prognostic factors, the risk of mortality is greater among rural patients with advanced stage endometrial cancer. Future studies should examine where patients are receiving treatment and how that impacts their survival and how to reduce the mortality rates of high risk patients.

Purpose: We sought to retrospectively examine clinical outcomes for three adjuvant vaginal high-dose-rate (HDR) brachytherapy regimens after hysterectomy for early-stage endometrial cancer., Methods: Included were women of all ages from two independent hospital systems diagnosed with Stage I-II endometrial cancer of any grade between 2000 and 2016 who underwent hysterectomy followed by adjuvant vaginal cylinder HDR brachytherapy with either 7.0 Gy × 3 fractions prescribed to 0.5 cm vaginal depth, 6.5 Gy × 3 fractions prescribed to 0.5 cm vaginal depth, or 6.0 Gy × 5 fractions prescribed to the vaginal surface. Outcomes included vaginal recurrence (VR), pelvic recurrence, distant recurrence, locoregional recurrence, recurrence-free survival, and overall survival., Results: Of the 348 women, 45 (13%) received 7.0 Gy × 3 fractions, 259 (74%) received 6.5 Gy × 3 fractions, and 44 (13%) received 6.0 Gy × 5 fractions. Women receiving 5-fraction brachytherapy were more likely to be younger with a higher performance status. At a median follow-up of 4.5 years, VR rates were 2.2%, 0.8%, and 4.5%, respectively. Multivariate analysis revealed no significant differences in the risks for VR among brachytherapy regimens. Risks for VR, pelvic recurrence, distant recurrence, locoregional recurrence, recurrence-free survival, and overall survival did not differ between propensity score-matched five- and 3-fraction brachytherapy cohorts., Conclusions: VR rates after hysterectomy and adjuvant vaginal brachytherapy for early-stage endometrial cancer were low and not significantly different by HDR dose fractionation., (Copyright © 2019 American Brachytherapy Society.

Objective: To analyze our institutional experience and oncologic outcomes for salvage treatment for the recurrence of early-stage endometrial cancer patients., Methods: We included women of all ages diagnosed with FIGO stage I-II, any grade endometrial cancer from 2000 to 2016 at our institutions who were treated with at least a hysterectomy. Recurrences in the pelvis and/or vagina were considered locoregional recurrences (LRR). Overall survival (OS) was assessed using Kaplan-Meier survival analysis. Univariate (UV) and multivariate (MV) Cox proportional hazards modeling was also used., Results: A total of 2691 women were analyzed. The majority had endometrioid histology (91%), stage IA disease (61%), and were grade 1 (57%). With a median follow-up of 6.1 years, the overall rate of recurrence was 7.2%, and the rate of LRR was 3.7%. Women with vaginal-only recurrences had a longer median OS after recurrence (14.0 years) compared to both pelvic (1.2 years) and distant (1.0 year) failures. For women with vaginal-only recurrences, salvage radiotherapy (RT) was the only factor associated with improved OS on MVA (HR 0.1, p = .04). For women with pelvic recurrences, salvage surgery (HR 0.3, p = .01), salvage RT (HR 0.3, p < .01), and salvage chemotherapy (HR 0.4, p = .03) were associated with improved OS., Conclusions: Failure rates for women with early-stage endometrial cancer are low. Women with vaginal-only recurrences have improved OS compared to pelvic or distant recurrences. Salvage RT appears to be an important factor for treatment of women with vaginal-only recurrences. Aggressive multimodality treatment may be beneficial for women with pelvic recurrences., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Objectives: Lymphovascular space invasion (LVSI) is a known prognostic factor for endometrial carcinomas. However, LVSI as a determinant of treatment benefit has not been fully elucidated., Methods and Materials: Data from the National Cancer Database for endometrial cancer from 2004 to 2012 was obtained. Univariate and multivariate analysis was performed to assess the impact of LVSI on overall survival (OS). Survival analysis was performed utilizing log-rank and Kaplan-Meier analyses. The difference in OS between external beam radiation therapy (EBRT) and vaginal brachytherapy (VBT) in LVSI-positive patients was analyzed with propensity score matching., Results: A total of 32,150 patients with surgical stage I to III endometrial carcinomas were available for analysis with a median follow-up of 30 months. Twenty-nine percent were LVSI positive and received adjuvant radiotherapy (aRT) more often than if LVSI negative (57% vs. 37%). On multivariate analysis, LVSI (hazard ratio, 1.94; P<0.01) was associated with an increased risk of death. aRT improved OS for LVSI-negative patients (87% without aRT, 90% with aRT; P=0.006). aRT was particularly effective in LVSI-positive patients: all stages of LVSI-positive patients were associated with an OS benefit (P<0.01), whereas among LVSI-negative patients, only stage III benefited from aRT (P<0.01). After propensity score match, there was no OS difference between EBRT and VBT among LVSI-positive patients (hazard ratio, 1.15; P=0.44)., Conclusions: LVSI is an independent prognostic factor in locoregional endometrial carcinomas. aRT benefited all stages of LVSI-positive patients, but only stage III of LVSI-negative patients. Among LVSI-positive patients, we did not find an OS difference between adjuvant EBRT versus VBT.

One woman dies from cervix cancer every 2 min, adding up to over 270,000 deaths globally per year. This cancer affects a young population, and hence, the loss of life is staggering. There are many aspects of prevention, screening, and care that are suboptimal. A great deal is known about HPV induced carcinogenesis, yet clinical outcomes have been stagnant over decades. There has been no improvement in cervix cancer survival in the US since the mid-1970s [1]. With increased knowledge of the disease and greater worldwide resources including prevention, screening, and improved therapeutics, there is significant promise for fewer women to die from this virally induced cancer. We focus here on the major problems in prevention, screening, and delivery of care for cervix cancer and provide concrete solutions. With appropriate focus, a major improvement in survival from cervix cancer could be achieved in a short time span., (Published by Elsevier Inc.)

Background: Endometrial cancer is the second most common cancer among female cancer survivors in the United States. Cardiovascular disease is the leading cause of death among endometrial cancer survivors. Studies that examine long-term cardiovascular outcomes among endometrial cancer survivors are critical., Methods: Cohorts of 2648 endometrial cancer survivors diagnosed between 1997 and 2012 and 10 503 age-matched women from the general population were identified. Cardiovascular disease diagnoses were identified from electronic medical records and statewide ambulatory surgery and statewide inpatient data. Cox regression models were used to estimate hazard ratios (HRs) at one to five years, more than five to 10 years, and more than 10 years after cancer diagnosis., Results: Between one and five years after diagnosis, increased cardiovascular risks among endometrial cancer survivors were observed for phlebitis, thrombophlebitis, and thromboembolism (HR = 2.07, 99% confidence interval [CI] = 1.57 to 2.72), pulmonary heart disease (HR = 1.74, 99% CI = 1.26 to 2.40), and atrial fibrillation (HR = 1.50, 99% CI = 1.07 to 2.11). At more than five to 10 years, some elevated risk persisted for cardiovascular diseases. Compared with patients who had surgery, patients who additionally had radiation therapy and/or chemotherapy were at increased risk for heart and circulatory system disorders between one and five years after cancer diagnosis. Older age and obesity were also risk factors for hypertension and heart disease among endometrial cancer survivors., Conclusions: Endometrial cancer survivors are at higher risk for various adverse long-term cardiovascular outcomes compared with women from the general population. This study suggests that increased monitoring for cardiovascular diseases may be necessary for endometrial cancer patients for 10 years after cancer diagnosis.

Objectives: Uterine carcinosarcoma (UCS) is a rare and aggressive cancer with poor survival. Our purpose was to evaluate the patterns-of-care and overall survival (OS) benefit of adjuvant chemoradiation (aCRT) compared with adjuvant chemotherapy (aCT) among UCS patients., Methods: A query was made in the National Cancer Database to identify patients with UCS diagnosed between 2004 and 2012. Factors predictive of OS were determined using univariate and multivariate Cox regression analysis, as well as Kaplan-Meier and log-rank analysis. Propensity-score matching was employed to decrease the potential influence of selection bias., Results: A total of 3538 patients were identified for analysis, consisting of 1787 patients (50.5%) receiving aCT and 1751 (49.5%) receiving aCRT. The median age of patients was 65 years. The majority of patients in our cohort were white (68.6%), on Medicare insurance (47.9%), with >5 cm tumor size (59.9%), and received a lymph node surgery (87.9%). The following factors were predictive of aCRT use: undergoing lymph node surgery (odds ratio, 1.59, P=0.01), and FIGO stage II (odds ratio, 1.71, P=0.01). Median survival for the aCT and aCRT groups was 24 months and 31.3 months, respectively. When compared with aCT alone, aCRT was associated with a benefit in OS on multivariate analysis (hazard ratio, 0.65, P<0.01)., Conclusions: When compared with aCT alone, the use of aCRT in UCS patients was associated with a significant OS benefit. Multiple demographic and clinical factors significantly influence the choice of adjuvant therapy in this setting.

The poly(ADP-ribose) polymerase-1/2 inhibitor veliparib is active against tumors deficient in homologous DNA damage repair. The pharmacokinetics and safety of veliparib extended-release (ER) were evaluated in patients with advanced solid tumors. This phase I study assessed veliparib-ER up to 800 mg once daily or 600 mg twice daily. Dose-limiting toxicities (DLTs), recommended phase II dose (RP2D), and maximum tolerated dose (MTD) were assessed in cycle 1 and safety/tolerability during continuous administration (28-day cycles). Seventy-one patients (n = 53 ovarian, n = 17 breast, n = 1 prostate carcinoma) received veliparib; 50 had deleterious breast cancer susceptibility (BRCA) gene mutations. Single-dose veliparib-ER 200 mg (fasting) led to 58% lower peak concentration and similar area under the concentration-time curve compared with veliparib immediate-release (IR). Three patients experienced DLTs (grade 2: asthenia; grade 3: nausea/vomiting, seizure). RP2D and MTD for veliparib-ER were 400 mg BID. The most frequent adverse events (AEs) were nausea (78.9%) and vomiting (50.7%). The most common grade 3/4 treatment-related AEs were as follows: thrombocytopenia (7.0%), nausea, and anemia (4.2% each). Overall, 12 (27.3%) patients with ovarian and 10 (62.5%) patients with breast carcinoma had a partial response. Veliparib-ER, versus veliparib-IR, exhibited an improved pharmacokinetic profile and was well tolerated in patients with ovarian and BRCA-mutated breast cancers., (© 2018 The Authors.

Objective: With the increasing incidence of endometrial cancer, the high survival rate, and the large number of endometrial cancer survivors, investigations of long-term genitourinary outcomes are important for the management of these outcomes among endometrial cancer survivors., Methods: Cohorts of 2648 endometrial cancer survivors diagnosed in the state of Utah between 1997 and 2012 and 10,503 general population women were identified. All ICD-9 diagnosis codes were collected from the state's two largest healthcare systems and statewide databases. Multivariate Cox regression models were used to estimate hazard ratios at 1-5years and >5-10years after endometrial cancer diagnosis for genitourinary outcomes., Results: Endometrial cancer survivors were at elevated risk for urinary system disorders between 1 and 5years (HR: 1.64, 95% CI: 1.50-1.78) and >5-10years (HR: 1.40, 95% CI: 1.26-1.56) and genital organ disorders between 1 and 5years (HR: 1.71, 95% CI: 1.58-2.03) and >5-10years (HR: 1.33, 95% CI: 1.19-1.49). Significantly elevated risk was observed among endometrial cancer survivors for renal failure, chronic kidney disease, urinary tract infections, and nonmalignant breast conditions, persisting between >5-10years. Between 1 and 5years after cancer diagnosis, those with higher stage, higher grade, older age and treated with radiation or chemotherapy were at higher risk for urinary disorders., Conclusions: Endometrial cancer survivors were at higher risk for many genitourinary outcomes compared to women from the general population. This study presents evidence suggesting the necessity of increased monitoring and counseling for genitourinary disorders for endometrial cancer patients both immediately after treatment cessation and for years afterwards., (Copyright © 2018 Elsevier Inc.

Background: Anti-HER2 therapies are associated with a risk of increased cardiac toxicity, particularly when part of anthracycline-containing regimens. We report cardiac safety of pertuzumab, trastuzumab, and chemotherapy in the neoadjuvant treatment of HER2-positive early breast cancer., Patients and Methods: BERENICE (NCT02132949) is a nonrandomized, phase II, open-label, multicenter, multinational study in patients with normal cardiac function. In the neoadjuvant period, cohort A patients received four cycles of dose-dense doxorubicin and cyclophosphamide, then 12 doses of standard paclitaxel plus four standard trastuzumab and pertuzumab cycles. Cohort B patients received four standard fluorouracil/epirubicin/cyclophosphamide cycles, then four docetaxel cycles with four standard trastuzumab and pertuzumab cycles. The primary end point was cardiac safety during neoadjuvant treatment, assessed by the incidence of New York Heart Association class III/IV heart failure and of left ventricular ejection fraction declines (≥10 percentage-points from baseline and to a value of <50%). The main efficacy end point was pathologic complete response (pCR, ypT0/is ypN0). Results are descriptive., Results: Safety populations were 199 and 198 patients in cohorts A and B, respectively. Three patients [1.5%; 95% confidence interval (CI) 0.31% to 4.34%] in cohort A experienced four New York Heart Association class III/IV heart failure events. Thirteen patients (6.5%; 95% CI 3.5% to 10.9%) in cohort A and four (2.0%; 95% CI 0.6% to 5.1%) in cohort B experienced at least one left ventricular ejection fraction decline. No new safety signals were identified. pCR rates were 61.8% and 60.7% in cohorts A and B, respectively. The highest pCR rates were in the HER2-enriched PAM50 subtype (75.0% and 73.7%, respectively)., Conclusion: Treatment with pertuzumab, trastuzumab, and common anthracycline-containing regimens for the neoadjuvant treatment of early breast cancer resulted in cardiac and general safety profiles, and pCR rates, consistent with prior studies with pertuzumab., Clinical Trial Information: NCT02132949.

Objectives: AL3818 (anlotinib) is a receptor tyrosine kinase inhibitor targeting vascular endothelial growth factor receptors (VEGFR1, VEGFR2/KDR, and VEGFR3), stem cell factor receptor (C-kit), platelet-derived growth factor (PDGFβ), and fibroblast growth factor receptors (FGFR1, FGFR2, and FGFR3). This study evaluates the efficacy of AL3818 studying tumor regression in an orthotopic murine endometrial cancer model., Methods: We tested the cytotoxicity of AL3818 on a panel of 7 human endometrial cancer cell lines expressing either wild-type or mutant FGFR2 and also assessed the in vivo antitumor efficacy in a murine, orthotopic AN3CA endometrial cancer model. AL3818 was administered daily per os either alone or in combination with carboplatin and paclitaxel, which represent the current standard of adjuvant care for endometrial cancer., Results: AL3818 significantly reduces AN3CA cell number in vitro, characterized by high expression of a mutated FGFR2 protein. Daily oral administration of AL3818 (5 mg/kg) resulted in a complete response in 55% of animals treated and in a reduced tumor volume, as well as decreased tumor weights of AN3CA tumors by 94% and 96%, respectively, following a 29-day treatment cycle. Whereas carboplatin and paclitaxel failed to alter tumor growth, the combination with AL3818 did not seem to exhibit a superior effect when compared with AL3818 treatment alone., Conclusions: AL3818 shows superior efficacy for the treatment of endometrial cancer irresponsive to conventional carboplatin and paclitaxel combination and warrants further investigation.

Metastatic breast cancer remains challenging to treat, and most patients ultimately progress on therapy. This acquired drug resistance is largely due to drug-refractory sub-populations (subclones) within heterogeneous tumors. Here, we track the genetic and phenotypic subclonal evolution of four breast cancers through years of treatment to better understand how breast cancers become drug-resistant. Recurrently appearing post-chemotherapy mutations are rare. However, bulk and single-cell RNA sequencing reveal acquisition of malignant phenotypes after treatment, including enhanced mesenchymal and growth factor signaling, which may promote drug resistance, and decreased antigen presentation and TNF-α signaling, which may enable immune system avoidance. Some of these phenotypes pre-exist in pre-treatment subclones that become dominant after chemotherapy, indicating selection for resistance phenotypes. Post-chemotherapy cancer cells are effectively treated with drugs targeting acquired phenotypes. These findings highlight cancer's ability to evolve phenotypically and suggest a phenotype-targeted treatment strategy that adapts to cancer as it evolves.

Background: The aims of this study were to assess the safety and tolerability of nanoparticle albumin bound paclitaxel (nab-paclitaxel), doxorubicin, and cyclophosphamide as combination therapy for breast cancer patients in the neoadjuvant setting and to assess the overall clinical response and pathologic complete response (pCR)., Patients and Methods: Twenty-six women with newly diagnosed stage II to III histologically or cytologically proven adenocarcinoma of the breast with negative HER2 status were enrolled. Patients were treated with nab-paclitaxel 100 mg/m 2 , doxorubicin 50 mg/m 2 , and cyclophosphamide 500 mg/m 2 on day 1 and nab-paclitaxel 100 mg/m 2 on day 8 in a 21-day cycle for 6 cycles total., Results: Most adverse events attributed to treatment were decreased white blood cell count, neutropenia, anemia, thrombocytopenia, and lymphopenia with a median duration of 8 days. Fifteen of 23 (65.2%; 95% confidence interval [CI], 45.7%-84.6%) had a complete clinical response and 8 of 23 (34.7%; 95% CI, 15.2%-54.1%) had a partial clinical response for an overall clinical response rate of 100%. Thirteen of 23 patients (56.5%; 95% CI, 36.2%-76.7%) had a pCR. All 10 triple-negative breast cancer (TNBC) patients (100%) achieved a pCR., Conclusion: The regimen of nab-paclitaxel, doxorubicin, and cyclophosphamide chemotherapy was well tolerated and resulted in high clinical as well as pathologic responses, particularly in TNBC., (Copyright © 2017 Elsevier Inc.

DNA double-strand breaks are typically repaired through either the high-fidelity process of homologous recombination (HR), in which BRCA1 plays a key role, or the more error-prone process of non-homologous end joining (NHEJ), which relies on 53BP1. The balance between NHEJ and HR depends, in part, on whether 53BP1 predominates in binding to damage sites, where it protects the DNA ends from resection. The nucleoporin Nup153 has been implicated in the DNA damage response, attributed to a role in promoting nuclear import of 53BP1. Here, we define a distinct requirement for Nup153 in 53BP1 intranuclear targeting to damage foci and report that Nup153 likely facilitates the role of another nucleoporin, Nup50, in 53BP1 targeting. The requirement for Nup153 and Nup50 in promoting 53BP1 recruitment to damage foci induced by either etoposide or olaparib is abrogated in cells deficient for BRCA1 or its partner BARD1, but not in cells deficient for BRCA2. Together, our results further highlight the antagonistic relationship between 53BP1 and BRCA1, and place Nup153 and Nup50 in a molecular pathway that regulates 53BP1 function by counteracting BRCA1-mediated events., Competing Interests: Competing interestsThe authors declare no competing or financial interests., (© 2017.

Objective: Early-stage high-risk endometrial cancer (HREC) treated with adjuvant radiotherapy (aRT) alone has been associated with an increased risk of distant relapse. The addition of chemotherapy to radiotherapy (aCRT) may benefit overall survival (OS). We investigated the patterns-of-care and OS benefit of aCRT in HREC by analyzing a large national registry., Methods: Our query was limited to patients with the International Federation of Gynecology and Obstetrics stage IB and II HREC with either papillary serous, clear cell, or grade 3 adenocarcinoma, diagnosed between 2004 and 2012. Logistic and Cox regression analyses were utilized to identify predictors of aCRT use and OS, respectively. Survival analysis was performed with Kaplan Meier and log-rank methods. Propensity score matching was employed to decrease the potential influence of selection bias., Results: A total of 11,746 patients were identified for analysis with 8206 (69.9%) receiving aCRT, and 3540 (30.1%) received aRT. Predictors of aCRT included International Federation of Gynecology and Obstetrics stage II (odds ratio [OR], 1.39; 95% confidence interval [CI], 1.22-1.57), papillary serous (OR, 9.44; 95% CI, 8.22-10.85) or clear cell (OR, 3.21; 95% CI, 2.59-3.97) histology, lymph nodes removed (OR, 1.48; 95% CI, 1.31-1.69), and receipt of brachytherapy alone (OR, 1.55; 95% CI, 1.36-1.78). Estimated 5-year OS was 75.2% for patients receiving aRT only and 79.2% for those receiving aCRT (P < 0.001). When compared with aRT, aCRT was associated with improved OS on multivariate (hazard ratio, 0.78; 95% CI, 0.61-0.99) analysis. A univariate shared-frailty Cox regression after propensity score matching revealed persistence of the OS benefit with aCRT (hazard ratio, 0.74; 95% CI, 0.65-0.84)., Conclusions: The addition of adjuvant chemotherapy to radiation in HREC is associated with improved OS. Multiple demographic and clinical factors significantly influence the choice of adjuvant therapy in this setting.

Purpose: The anticancer activity of valproic acid (VPA) is attributed to the inhibition of histone deacetylase. We previously published the genomically derived sensitivity signature for VPA (GDSS-VPA), a gene expression biomarker that predicts breast cancer sensitivity to VPA in vitro and in vivo. We conducted a window-of-opportunity study that examined the tolerability of VPA and the ability of the GDSS-VPA to predict biologic changes in breast tumors after treatment with VPA., Patients and Methods: Eligible women had untreated breast cancer with breast tumors larger than 1.5 cm. After a biopsy, women were given VPA for 7 to 12 days, increasing from 30 mg/kg/d orally divided into two doses per day to a maximum of 50 mg/kg/d. After VPA treatment, serum VPA level was measured and then breast surgery or biopsy was performed. Tumor proliferation was assessed by using Ki-67 immunohistochemistry. Histone acetylation of peripheral blood mononuclear cells was assessed by Western blot. Dynamic contrast-enhanced magnetic resonance imaging scans were performed before and after VPA treatment., Results: Thirty women were evaluable. The median age was 54 years (range, 31-73 years). Fifty-two percent of women tolerated VPA at 50 mg/kg/d, but 10% missed more than two doses as a result of adverse events. Grade 3 adverse events included vomiting and diarrhea (one patient) and fatigue (one patient). The end serum VPA level correlated with a change in histone acetylation of peripheral blood mononuclear cells (ρ = 0.451; P = .024). Fifty percent of women (three of six) with triple-negative breast cancer had a Ki-67 reduction of at least 10% compared with 17% of other women. Women whose tumors had higher GDSS-VPA were more likely to have a Ki-67 decrease of at least 10% (area under the curve, 0.66)., Conclusion: VPA was well tolerated and there was a significant correlation between serum VPA levels and histone acetylation. VPA treatment caused a decrease in proliferation of breast tumors. The genomic biomarker correlated with decreased proliferation. Inhibition of histone deacetylase is a valid strategy for drug development in triple-negative breast cancer using gene expression biomarkers., Competing Interests: Window-of-Opportunity Study of Valproic Acid in Breast Cancer Testing a Gene Expression BiomarkerThe following represents disclosure information provided by authors of this manuscript.

Objectives: Guidelines suggest that secondary reflex testing may be useful for resolving HER2 status in breast cancers with equivocal results by both immunohistochemistry (IHC) and in situ hybridization (ISH). We compared two reflex ISH assays and a polymerase chain reaction (PCR) assay for this application., Methods: Twenty-nine breast cancers with equivocal IHC and ISH results were retested two ways: (1) ISH using differentially labeled probes targeting ERBB2 ( HER2 , 17q12) and either RAI1 (17p11.2) or ORC4 (2q22.3-2q23.1) in two separate assays and (2) real-time quantitative PCR amplification of ERBB2 and a control locus ( EIF5B , 2q11.2)., Results: Results of the HER2 / RAI1 and HER2 / ORC4 ISH assays were concordant for 21 (72%) cases, and results of all three secondary reflex assays were concordant for only 18 (62%) cases. Result discrepancies between the two ISH readers were observed for cases close to the cutoff threshold., Conclusions: Use of different control loci for ISH is associated with discordant results, and PCR is more likely to classify cases as nonamplified, possibly due to contamination with nontumor cells. While resolution of HER2 -equivocal results is desirable from a clinical perspective, different secondary reflex assays yield different results, and the correlation of these results with clinical outcomes is unknown., (© American Society for Clinical Pathology, 2016.

Purpose: Belinostat is an inhibitor of histone deacetylase enzymes, resulting in DNA repair inhibition and apoptosis. Present data are lacking to provide dosing recommendations in renal insufficiency. The purpose of this trial was to assess the pharmacokinetics (PK) of belinostat and belinostat metabolites in plasma and urine., Methods: This was a phase I, single-center, open-label, two-part study. In Part I, patients received single-agent belinostat 1000 mg/m 2 . Blood and urine samples were collected at pre-specified time points to determine PK of belinostat and metabolites and their elimination in urine. In Part II, patients were permitted to continue belinostat in 21-day cycles on Days 1 through 5 until disease progression, unacceptable toxicity, or according to patient preference., Results: A total of nine patients with advanced solid tumors were treated. Median t max for belinostat was observed 10 min after the start of infusion. Concentrations of belinostat rapidly declined with a t 1/2 of 2.9 h. The mean fraction of belinostat excreted unchanged in urine was 0.926 %. The metabolites belinostat glucuronide and 3-ASBA represented the largest fractions of belinostat dose excreted in urine (30.5 and 4.61 %, respectively), while renal excretion appeared to be a minor route of elimination for the parent belinostat (<1 %). The most common adverse events were nausea, fatigue, and diarrhea. One Grade 3 adverse event (constipation) was thought to be treatment related., Conclusions: Urinary elimination of parent belinostat was minimal, although a combined 36.7 % of belinostat metabolites were excreted in urine. Since these metabolites are primarily inactive, belinostat may not require dosage adjustment in renal dysfunction.

Objectives: Guidelines for HER2 testing define an equivocal range for HER2 using two approved testing methods, immunohistochemistry (IHC) and in situ hybridization (ISH). We investigated genome-wide copy number alterations in this subgroup., Methods: Ten breast cancers with equivocal HER2 status by both IHC and ISH were analyzed by single-nucleotide polymorphism cytogenomic microarray (SNP array). DNA ploidy analysis by flow cytometry was performed on nine cases with sufficient material remaining., Results: SNP array analysis showed uniform gain of chromosome 17 (polysomy) in one case and segmental copy number gains encompassing HER2 and the centromere in five other cases. Flow cytometry revealed hyperdiploidy in six cases, all but one of which also had HER2 gains on SNP array. Although there was no evidence of HER2 amplification by SNP array, six cases showed amplification of other genomic regions, including known oncogenes in four cases., Conclusions: A combination of hyperdiploidy and segmental copy number gains contributes to HER2 ISH-equivocal results in most breast cancers. Cases in which HER2 copy number gain is not corroborated by genomic analysis suggest the presence of other contributing variables influencing ISH results. Genomic copy number analysis also implicates non-HER2 oncogenic drivers in many cases that are HER2 equivocal., (© American Society for Clinical Pathology, 2016. All rights reserved.

This selection from the NCCN Guidelines for Ovarian Cancer focuses on the less common ovarian histopathologies (LCOHs), because new algorithms were added for LCOHs and current algorithms were revised for the 2016 update. The new LCOHs algorithms include clear cell carcinomas, mucinous carcinomas, and grade 1 (low-grade) serous carcinomas/endometrioid epithelial carcinomas. The LCOHs also include carcinosarcomas (malignant mixed Müllerian tumors of the ovary), borderline epithelial tumors (also known as low malignant potential tumors), malignant sex cord-stromal tumors, and malignant germ cell tumors., (Copyright © 2016 by the National Comprehensive Cancer Network.)

Purpose: Trametinib is a reversible, selective inhibitor of the mitogen-activated extracellular signal-regulated kinase 1 (MEK1) and 2 (MEK2). Cardiotoxicity (congestive heart failure, decreased heart rate, left ventricular dysfunction, and hypertension) related to trametinib is an infrequent, but serious, adverse event (AE). Prolongation of the QT interval increases the risk of life-threatening cardiac arrhythmia. Thus, the risk of trametinib inducing QT prolongation at putative supratherapeutic exposure was evaluated., Methods: Eligible patients with solid tumours received placebo on day 1, once-daily trametinib 2-mg doses on days 2-14, and a single trametinib 3-mg dose on day 15 to achieve supratherapeutic dosing for QTc measurement. Electrocardiogram was assessed by 12-lead ambulatory 24-h Holter monitoring pre-dose, and on day 1 and day 15. Pharmacokinetic (PK) and pharmacodynamics (PD) parameters were measured., Results: Thirty-two of 35 patients completed the study. There was no effect of trametinib when compared with time-matched placebo on the change from baseline in QTcF, QTcB, or QTcI interval. Mean AUC0-24 and C max following trametinib 2-mg repeat doses were 364 ng.h/mL and 22.9 ng/mL, respectively; the corresponding values for the 3-mg dose were 454 ng.h/mL and 29.2 ng/mL. Median T max was approximately 2 h for both doses. Statistical analysis and PK/PD modelling showed no significant relationship between QTcF interval and trametinib plasma concentrations. AEs were consistent with those reported previously. No electrocardiogram abnormalities were reported as AEs., Conclusions: The results of this study suggest trametinib has no significant effect on QT prolongation at supratherapeutic exposure.

Purpose: We aimed to investigate the patterns-of-care and overall survival (OS) benefit of aCRT versus adjuvant monotherapy (aMT), defined as either chemotherapy or radiation alone, utilizing a large national registry of patients., Patients and Methods: Adult patients with stage III endometrial adenocarcinoma diagnosed from 2004 to 2013 were included. Logistic and Cox regression modeling was used to identify factors predictive of receipt of aCRT and OS, respectively. Survival analysis was performed with Kaplan Meier and log-rank analysis. Propensity score matching and sensitivity analysis was performed to address selection bias and presence of potential confounding variables., Results: A total of 21,027 patients were identified: 11,435 (54.4%) patients received aMT, while 9592 (45.6%) received aCRT. Utilization of aCRT increased over the study period (p<0.01). Factors predictive of receiving aCRT include private insurance (OR: 1.67, 95% CI: 1.30-2.14), Medicare (OR: 1.33, 95% CI: 1.01-1.75), FIGO stage IIIC disease (OR: 1.36, 95% CI: 1.19-1.54), lymphovascular space invasion (OR: 1.14, 95% CI: 1.03-1.27), and lymph node surgery performed (OR: 1.42, 95% CI: 1.15-1.74). Median survival in years for aCRT, RT, and CT was 10.3, 7.1, and 5.6, respectively (p<0.001). Compared to aMT, aCRT was associated with a decrease risk of death on multivariate analysis (HR: 0.62, 95% CI: 0.56-0.70). The benefit of aCRT over aMT persisted after propensity score matching., Conclusion: The use of aCRT for stage III endometrial cancer is increasing. Multiple clinical and demographic factors were predictive of aCRT use. When compared to chemotherapy or radiation alone, aCRT is associated with an OS benefit., (Copyright © 2016 Elsevier Inc.
