The majority of patients with advanced ovarian cancer progress after first-line therapy and require further treatment. Tumor biology, prior chemotherapy, responses to previous therapy, performance status, and toxicity are the characteristics that influence treatment choice. These criteria have been linked to the time between relapse and last platinum therapy: the platinum-free interval. Today, patients are classified as either those who are eligible for a new platinum-based therapy or those for whom platinum is not an option. A nonplatinum regimen should be administered to patients who are not candidates for platinum re-treatment. This group includes patients with early relapse after, or progression during, previous platinum-based chemotherapy and patients with platinum intolerability. A single agent such as weekly paclitaxel, pegylated liposomal doxorubicin (PLD), gemcitabine, or topotecan represents the standard. For patients not treated with bevacizumab in the first line, this drug should be added to chemotherapy. For patients for whom platinum rechallenge is an option (because they are potentially platinum-responsive), different strategies are available with the incorporation of biological drugs targeting angiogenesis or the mechanisms of DNA repair. A BRCA mutation status predicts a better response to platinum and poly(adenosine diphosphate-ribose) polymerase (PARP) inhibition. PARP inhibitors and antiangiogenic drugs have proven efficacy as maintenance therapy after chemotherapy and concurrently with chemotherapy, respectively. These agents have changed current practice, although few biomarkers are available to guide decisions. Patients potentially responsive to platinum who cannot receive the drug again can be treated with a combination of trabectedin and PLD, the most active nonplatinum therapy in this setting.

Among the pharmaceutical options available for treatment of ovarian cancer, increasing attention has been progressively focused on pegylated liposomal doxorubicin (PLD), whose unique formulation prolongs the persistence of the drug in the circulation and potentiates intratumor accumulation. Pegylated liposomal doxorubicin (PLD) has become a major component in the routine management of epithelial ovarian cancer. In 1999 it was first approved for platinum-refractory ovarian cancer and then received full approval for platinum-sensitive recurrent disease in 2005. PLD remains an important therapeutic tool in the management of recurrent ovarian cancer in 2012. Recent interest in PLD/carboplatin combination therapy has been the object of phase III trials in platinum-sensitive and chemonaıve ovarian cancer patients reporting response rates, progressive-free survival, and overall survival similar to other platinum-based combinations, butwith amore favorable toxicity profile and convenient dosing schedule. This paper summarizes data clarifying the role of pegylated liposomal doxorubicin (PLD) in ovarian cancer, as well as researches focusing on adding novel targeted drugs to this cytotoxic agent.

Objectives: Adjuvant treatment for stage III endometrial cancer is not yet defined. Previous experiences support the usefulness of combined chemotherapy and radiotherapy. The aim of this retrospective study was to describe the outcome in a cohort of patients with stage III endometrial cancer treated with chemotherapy and/or radiotherapy. Methods: A multicenter retrospective analysis of patients with stage III endometrial cancer from 1998 to 2009 was conducted. The impact on relapse-free survival of clinical and pathological variables and adjuvant treatment received was analyzed by univariate and multivariate analysis. Results: Eighty-two patients were considered. Median age was 62 years (range 38-82). Seventy-eight (95%) patients received an adjuvant treatment: chemotherapy (41; 50%), radiotherapy (18; 22%), or combined chemo-radiotherapy (19; 23%). Four patients were excluded from analysis because they were not treated with any adjuvant therapy. At univariate analysis, tumor grade (G3 vs. G1-G2; p = 0.003) was associated with risk of recurrence; similarly, patients treated with radiotherapy alone (p = 0.031, hazard ratio 0.19, 95% CI 0.04-0.86) or chemotherapy alone (p = 0.053, hazard ratio 0.54, 95% CI 0.29-1.01) had a significantly higher risk for relapse, compared to those treated with the multimodality approach. Relapse-free survival at 3 years was 86.5, 65.8 and 44.1%, with the multimodality approach, chemotherapy and radiotherapy, respectively. At multivariable analysis, age and grading were independently associated with recurrence-free survival. Hazard ratio for relapse-free survival was 0.14 (95% CI 0.02-1.04) and 0.20 (95% CI 0.04-1.11) for multimodality treatment compared to chemotherapy alone and radiotherapy alone, respectively. Conclusions: Age and grading are independent prognostic factors. A combined approach with radiotherapy and chemotherapy may induce an advantage in relapse-free survival compared to radiotherapy or chemotherapy alone. Prospective clinical trials are needed to verify this clinical hypothesis. Copyright © 2011 S. Karger AG, Basel [ABSTRACT FROM AUTHOR]

Capecitabine is an oral chemotherapeutic agent, already used in breast and colon cancer. Previous data showed encouraging results in the treatment of recurrent ovarian cancer. The aim of this study was to describe activity and toxicity of capecitabine in patients with platinum resistant or refractory ovarian cancer. Patients were eligible if they had cytologically or histologically proven epithelial ovarian cancer, refractory or resistant to prior platinum-containing chemotherapy. Capecitabine was administered at the dose of 1,250 mg/m2 twice daily on days 1–14 of a 21-day cycle for a maximum of six cycles. The primary end point of the study was activity in terms of objective response rate in according to RECIST criteria. A two-stage minimax design for phase II studies was used: at least four objective responses had to be reached among 32 evaluable patients to define the treatment active. Between March 2006 and October 2007, 36 patients were enrolled. All patients had ovarian cancer and 83.3% had previously received two or three lines of chemotherapy. Thirty-two patients were evaluable for response and included in the activity analysis. The objective response rate was 3.1% [95% exact confidence interval (CI): 0.08–16.22%], lower than the threshold required to define the treatment as active. The median progression free survival was 68 days (95% CI: 65–120). Haematological toxicity was not frequent. Nausea and fatigue were common, but never severe, and they were observed in 13 (37.1%) and 12 (34.2%) patients, respectively. Diarrhoea occurred in 11 patients (31.5%) and it was of grade 3 in 8.6% of cases. Grade 1–2 stomatitis was observed in seven patients (20%). Cardiovascular toxicity was reported in two cases, including a death for pulmonary embolism. Capecitabine is not active in platinum resistant non mucinous ovarian cancer, producing a response rate lower than that required by study design. Further trials are not warranted in these patients.

To report long-term efficacy and safety of selinexor maintenance therapy in adults with TP53 wild-type (TP53 wt) stage IV or recurrent endometrial cancer (EC) who achieved partial remission (PR) or complete remission (CR) following chemotherapy. Analysis of the prespecified, exploratory subgroup of patients with TP53 wt EC from the phase 3 SIENDO study was performed. Progression-free survival (PFS) benefit in patients with TP53 wt EC and across other patient subgroups were exploratory endpoints. Safety and tolerability were also assessed. Of the 263 patients enrolled in the SIENDO trial, 113 patients had TP53 wt EC; 70/113 (61.9%) had TP53 wt/proficient mismatch repair (pMMR) EC, and 29/113 (25.7%) had TP53 wt/deficient mismatch repair (dMMR) EC. As of April 1, 2024, the median PFS (mPFS) for TP53 wt patients who received selinexor compared with placebo was 28.4 versus 5.2 months (36.8-month follow-up, HR 0.44; 95% CI 0.27–0.73). A benefit in mPFS was seen with selinexor versus placebo regardless of MMR status (patients with TP53 wt/pMMR EC: 39.5 vs 4.9 months, HR 0.36; 95% CI 0.19–0.71; patients with TP53 wt/dMMR EC: 13.1 vs 3.7 months, HR 0.49; 95% CI 0.18–1.34). Selinexor treatment was generally manageable, with no new safety signals identified. In the phase 3 SIENDO study, selinexor maintenance therapy showed a promising efficacy signal and a manageable safety profile in the prespecified subgroup of patients with TP53 wt EC who achieved a PR or CR following chemotherapy. These results are being further evaluated in an ongoing randomized phase 3 trial (NCT05611931). [Display omitted] • Patients with TP53 wild-type (wt) advanced or recurrent endometrial cancer have limited effective treatment options. • Selinexor is an oral exportin 1 (XPO1) inhibitor activating p53 through nuclear retention of key tumor suppressor proteins. • Meaningful increase in median progression-free survival (mPFS) of TP53 wt were seen with selinexor maintenance therapy. • Increase in mPFS with selinexor in TP53 wt subgroup was observed regardless of mismatch repair status. • Selinexor was generally manageable, with no new safety signals observed.

To assess patient-reported health-related quality of life (HRQoL) in patients with ovarian cancer (OC) who received niraparib as first-line maintenance therapy. PRIMA/ENGOT-OV26/GOG-3012 (NCT02655016) enrolled patients with newly diagnosed advanced OC who responded to first-line platinum-based chemotherapy. Patients were randomized (2:1) to niraparib or placebo once daily in 28-day cycles until disease progression, intolerable toxicity, or death. HRQoL was assessed as a prespecified secondary end point using patient-reported responses to the European Organisation for Research and Treatment of Cancer QOL Questionnaire (EORTC QLQ-C30), the EORTC QLQ Ovarian Cancer Module (EORTC QLQ-OV28), the Functional Assessment of Cancer Therapy–Ovarian Symptom Index (FOSI), and EQ-5D-5L questionnaires. Assessments were collected at baseline and every 8 weeks (±7 days) for 56 weeks, beginning on cycle 1/day 1, then every 12 weeks (±7 days) thereafter while the patient received study treatment. Among trial participants (niraparib, n = 487; placebo, n = 246), PRO adherence exceeded 80% for all instruments across all cycles. Patients reported no decline over time in HRQoL measured via EORTC QLQ-C30 Global Health Status/QoL and FOSI overall scores. Scores for abdominal/gastrointestinal symptoms (EORTC QLQ-OV28) and nausea and vomiting, appetite loss, and constipation (EORTC QLQ-C30) were higher (worse symptoms) in niraparib-treated patients than placebo-treated patients; except for constipation, these differences resolved over time. Patients did not self-report any worsening from baseline of fatigue, headache, insomnia, or abdominal pain on questionnaires. Despite some early, largely transient increases in gastrointestinal symptoms, patients with OC treated with niraparib first-line maintenance therapy reported no worsening in overall HRQoL. [Display omitted] • Detailed analysis of patient-reported outcomes from the PRIMA trial of niraparib as a first-line maintenance therapy. • Compared with placebo, niraparib-treated patients self-reported worse symptoms of constipation, nausea/vomiting, and appetite loss. • Except for constipation, the increase in gastrointestinal symptoms compared with placebo resolved over time. • No worsening of fatigue, headache, insomnia, or abdominal pain over time were noted on self-reported questionnaires. • Overall quality of life was generally maintained with niraparib treatment despite patient-reported gastrointestinal symptoms.

Simple Summary: This multicenter, retrospective analysis had the objective of comparing the efficacy of PLD-Trabectedin in patients who had already been treated with PARP-I (cases) before vs. PARPi-naïve patients (controls). Data from 166 patients were collected, composed of 109 cases and 57 controls. In total, 135 patients were included in our analyses, composing 46 controls and 89 cases. We found a median PFS of 11 months (95% IC 10–12) in the control group vs. 8 months (95% IC 6–9) in the case group (p value 0.0017). The clinical benefit rate was evaluated, with an HR for progression of 2.55 (1.28–5.06) for the case group (p value 0.008) persisting when adjusted for BRCA mutation. The study showed a statistically significant difference in terms of PFS, suggesting that a previous exposure to PARP-i might inhibit the efficacy of PLD-Trabectedin. Regarding tolerability, no remarkable disparity was noted. Objective: While PLD-Trabectedin is an approved treatment for relapsed platinum-sensitive ovarian cancer, its efficacy and tolerability has so far not been tested extensively in patients who progress after poly ADP-ribose polymerase inhibitor (PARPi) treatment. Methodology: This multicenter, retrospective analysis had the objective of comparing patients receiving PLD-Trabectedin after being treated with PARP-I (cases) with PARPi-naïve patients. Descriptive and survival analyses were performed for each group. Results: Data from 166 patients were collected, composed of 109 cases and 57 controls. In total, 135 patients were included in our analyses, composing 46 controls and 89 cases. The median PFS was 11 months (95% IC 10–12) in the control group vs. 8 months (95% IC 6–9) in the case group (p value 0.0017). The clinical benefit rate was evaluated, with an HR for progression of 2.55 (1.28–5.06) for the case group (p value 0.008), persisting when adjusted for BRCA and line with treatment. We compared hematological toxicity, gastro-intestinal toxicity, hand–foot syndrome (HFS), fatigue, and liver toxicity, and no statistically significant disparity was noted, except for HFS with a p value of 0.006. The distribution of G3 and G4 toxicities was also equally represented. Conclusion: The MITO39 study showed a statistically significant difference in terms of PFS, suggesting that previous exposure to PARPi might inhibit the efficacy of PLD-Trabectedin. Regarding tolerability, no remarkable disparity was noted; PLD-Trabectedin was confirmed to be a well-tolerated scheme in both groups. To our knowledge, these are the first data regarding this topic, which we deem to be of great relevance in the current landscape. [ABSTRACT FROM AUTHOR]

Non-clear cell renal cell carcinoma (nccRCC) is a heterogeneous group representing 15–30% of renal tumors. They are mostly excluded from immunotherapy trials due to their rarity and worse prognosis. This, alongside nccRCC misdiagnosis/misclassification, lack of immune-biomarker expression rate data, lack of homogeneous data reporting, the retrospective nature of many studies, small sample sizes, and the fact that high-grade evidence only stems from trials mostly addressing the clear cell subtype, result in poorly defined treatments. We thus reviewed available data from several clinical trials, retrospective studies, and meta-analyses on immunotherapy responses and their correlation with histological subtypes and prognostic biomarkers. The papillary and unclassified subtypes are the best candidate for immunotherapy, showing response rates up to ∼35%. Chromophobe cancers, on the other end, have mostly null response rates. Cancers with sarcomatoid features respond very well to immunotherapy, regardless of their histology. Available data for translocation, medullary, collecting duct, and other nccRCCs are inconclusive. Regarding PD-L1, its expression correlates with better responses, but its prognostic value remains to be determined due to small sample sizes hindering direct statistical comparisons. It is necessary to involve a larger number of nccRCC patients and centers in clinical trials and report tumor response rates and PD-(L)1 and other markers' expression rates divided by nccRCC subtypes and not just for the whole cohorts. This will allow us to collect more robust data to best identify patients who can benefit from immunotherapy and ultimately define the standard of treatment. N/A [Display omitted] • Immunotherapy treatment for unresectable non-clear cell renal cell carcinoma is not defined due to lack of data. • Papillary and unclassified histology are the subtypes with better response rates. • Chromophobe carcinomas do not respond well to immunotherapy. • Tumors with sarcomatoid features respond very well, regardless of their histology. • PD-L1 expression correlates with better responses, but its prognostic value remains to be determined.

Background: The PRIMA/ENGOT‐OV26/GOG‐3012 (NCT02655016) trial was amended to prospectively evaluate the safety and efficacy of an individualized starting dose (ISD) regimen of niraparib for first‐line maintenance therapy in patients with newly diagnosed advanced ovarian cancer. Methods: In the phase 3 PRIMA trial, patients with newly diagnosed advanced ovarian cancer with a complete/partial response to first‐line platinum‐based chemotherapy (N = 733) were initially treated with a fixed starting dose (FSD) regimen of 300 mg once daily. Subsequently, the protocol was amended so newly enrolled patients received an ISD: 200 mg once daily in patients with baseline body weight < 77 kg or baseline platelet count < 150,000/µL, and 300 mg once daily in all other patients. Efficacy and safety outcomes were assessed by starting dose. Results: Overall, 475 (64.8%) patients were assigned to an FSD (niraparib, n = 317; placebo, n = 158) and 258 (35.2%) were assigned to an ISD (niraparib, n = 170; placebo, n = 88). Efficacy in patients who received FSD or ISD was similar for the overall (FSD hazard ratio [HR], 0.59 [95% CI, 0.46–0.76] vs. ISD HR, 0.69 [95% CI, 0.48–0.98]) and the homologous recombination–deficient (FSD HR, 0.44 [95% CI, 0.30–0.64] vs. ISD HR, 0.39 [95% CI, 0.22–0.72]) populations. In patients with low body weight/platelet count, rates of grades ≥3 and 4 hematologic treatment‐emergent adverse events, dose interruptions, and dose reductions were lower for those who received ISD than for those who received FSD. Conclusions: In PRIMA, similar dose intensity, similar efficacy, and improved safety were observed with the ISD compared with the FSD regimen. Results from the phase 3 PRIMA trial of niraparib first‐line maintenance therapy that prospectively evaluated fixed versus individualized dosing support the selection of a niraparib starting dose based on an individual's body weight and platelet count. In prespecified analyses, patients who received the individualized starting dose of niraparib experienced similar progression‐free survival and improved safety outcomes compared with patients who received the fixed starting dose of niraparib.

The aim of the present analysis was to explore the efficacy of Bevacizumab (Bev) on survival outcome in advanced low grade serous ovarian cancer (LGSOC) both in first line and in recurrent setting. In retrospective observational multicenter study, we described the outcome of LGSOC patients enrolled in the MITO 22 study and treated with chemotherapy (CT) with or without Bev. Patients receiving Bev in first-line or in recurrence were considered and compared with patients receiving CT alone (stage III and IV in first line; platinum based-CT in second line). Descriptive and survival analyses were performed for each group. Out of 128 patients included in MITO 22, 46 LGSOC patients receiving Bev in first line setting or at the time of first recurrence were identified. In first line, 30 patients received Bev + CT and 65 CT alone and the median PFS were 47.86 months (95% CI: 31.48 - NR) and 22.63 months (95% CI 15–39.24) (p -value 0.0392), respectively. In the recurrent setting, 16 patients who received Bev + CT were compared to 33 women treated with platinum-based CT alone. Median PFS were 37.1 months (95% CI: 13.42–40.56) and 11.22 months (95% CI: 8.26–15.63) (p-value 0.013), respectively. Our study suggests that Bev might be effective in LGSOC both at diagnosis and at the time of relapse. These data warrants further studies. • Bevacizumab shows antitumor activity in LGSC at the time of diagnosis and at the time of first recurrence. • A total of 46 LGSC patients received Bevacizumab in combination with CT and were compared to patients treated with CT alone. • A statistically significant advantage in terms of PFS were reported in the group of patients treated with Bev + CT.

Adding immunotherapy to first-line chemotherapy might improve outcomes for patients with advanced or recurrent endometrial cancer. We aimed to compare carboplatin and paclitaxel versus avelumab plus carboplatin and paclitaxel as first-line treatment with avelumab given concurrent to chemotherapy and as maintenance after the end of chemotherapy. MITO END-3 is an open-label, randomised, controlled, phase 2 trial conducted at 31 cancer institutes, hospitals, and universities in Italy. Eligible patients were aged 18 years or older with histologically confirmed advanced (FIGO stage III–IV) or recurrent endometrial cancer, an Eastern Cooperative Oncology Group (ECOG) performance status of 0–1, and no previous systemic anticancer therapy as primary treatment for advanced or metastatic disease. Participants were randomly assigned (1:1) using a computerised minimisation procedure stratified by centre, histology, and stage at study entry, to either receive carboplatin (area under the curve [AUC] 5 mg/mL × min) and paclitaxel (175 mg/m2; standard group) intravenously every 3 weeks for six to eight cycles or avelumab (10 mg/kg intravenously) added to carboplatin and paclitaxel (experimental group) every 3 weeks and then every 2 weeks as a single maintenance treatment after the end of chemotherapy until disease progression or unacceptable toxicity. Patients, treating clinicians, and those assessing radiological examinations were not masked to study treatment. The primary endpoint was investigator-assessed progression-free survival, measured in the intention-to-treat (ITT) population. Patients who received at least one dose of study drug were included in the safety analysis. Experimental group superiority was tested with 80% power and one-tailed α 0·20. This trial is registered with ClinicalTrials.gov (NCT03503786) and EudraCT (2016–004403–31). From April 9, 2018, to May 13, 2021, 166 women were assessed for eligibility and 39 were excluded. 125 eligible patients were randomly assigned to receive carboplatin and paclitaxel (n=62) or avelumab plus carboplatin and paclitaxel (n=63) and included in the ITT population. The median follow-up was 23·3 months (IQR 13·2–29·6) and was similar between the two groups. 91 progression-free survival events were reported, with 49 events in 62 patients in the standard group and 42 events in 63 patients in the experimental group. The median progression-free survival was 9·9 months (95% CI 6·7–12·1) in the standard group and 9·6 months (7·2–17·7) in the experimental group (HR of progression or death 0·78 [60% CI 0·65–0·93]; one-tailed p=0·085). Serious adverse events were reported more frequently in the experimental group (24 vs seven events in the standard group); neutrophil count decrease was the most frequent grade 3–4 adverse event (19 [31%] of 61 patients in the experimental group vs 26 [43%] of 61 patients in the standard group). Two deaths occurred in the experimental group during treatment (one respiratory failure following severe myositis [possibly related to treatment] and one cardiac arrest [not related to treatment]). Adding avelumab to first-line chemotherapy deserves further testing in patients with advanced or recurrent endometrial cancer, although consideration of mismatch repair status is warranted. Pfizer.

This open-label phase II clinical trial evaluated the antitumor activity and safety of trabectedin in patients with advanced ovarian (OC) or uterine carcinosarcomas (UC). Eligible patients were adults (≥18 years) with histologically proven recurrent OC/UC not amenable to surgery or radiotherapy who received up to two prior chemotherapy lines. Trabectedin 1.3 mg/m2 was administered as a 3-h infusion every three weeks. The primary endpoint was objective response rate (ORR) as per RECIST v.1.1. If at least 8 of 43 patients (18.6%) achieve an objective response, trabectedin would be declared worthy for further investigations. Forty-five patients with either OC (n = 32) or UC (n = 13) from seven MITO centers across Italy were enrolled. The ORR was 11.9% (90% CI: 6–23) and included two patients with a complete response and three with a partial response. Eight patients (19.0%) had disease stabilization for a disease control rate of 31.0% (90% CI: 20–44). Median progression-free survival was 2.01 months (95% CI: 1.78–2.30) and median overall survival was 4.64 months (95% CI: 3.19–8.29). Neutrophil count decreases (n = 8, 18.2%) and transaminase increases (n = 6, 13.6%) were the most common grade 3–5 adverse events related with trabectedin. Two patients died due to trabectedin-related grade 5 hematological toxicity. Although trabectedin did not meet the prespecified activity criteria, it confers modest but clinically meaningful benefit to patients with advanced OC/UC as being as effective as any other available treatment for this indication. The toxicity profile appears in line with that previously reported for the drug. • Trabectedin did not meet the prespecified activity criteria to be considered worthy for further investigations in OC or UC. • Yet, in heavily pre-treated patients trabectedin elicited modest clinical benefit comparable with other available drugs. • Trabectedin was well tolerated, with a safety profile consistent with previous experiences.

Background: Low-grade serous ovarian and peritoneal cancer (LGSC) is a rare disease and few data on the clinical and genomic landscape have been published.Methods: A retrospective analysis of patients diagnosed with LGSC between 1996 and 2019 was conducted in MITO centers. Objective Response Rate (ORR) to treatments, progression-free survival (PFS) and overall survival (OS) were assessed. Additionally, the tumor molecular profile of 56 patients was evaluated using the Next Generation Sequencing (NGS) FoundationOne CDX (Foundation Medicine®).Results: A total of 128 patients with complete clinical data and pathologically confirmed diagnosis of LGSC were identified. ORR to first and subsequent therapies were 23.7% and 33.7%, respectively. PFS was 43.9 months (95% CI:32.4-53.1) and OS was 105.4 months (95% CI: 82.7-not reached). The most common gene alterations were: KRAS (n = 12, 21%), CDKN2A/B (n = 11, 20%), NRAS (n = 8, 14%), FANCA (n = 8, 14%), NF1 (n = 7, 13%) and BRAF (n = 6, 11%). Unexpectedly, pathogenetic BRCA1 (n = 2, 4%), BRCA2 (n = 1, 2%) and PALB2 (n = 1, 2%) mutations were found.Conclusions: MITO 22 suggests that LGSC is an heterogenous disease for both its clinical behavior in response to standard therapies and its molecular alterations. Future prospective studies should test treatments according to biological and molecular tumor's characteristics.Clinical Trial Registration: This study is registered under NCT02408536 on ClinicalTrials.gov .

To find prognostic factors for advanced ovarian cancer patients undergoing first-line therapy with carboplatin, paclitaxel and bevacizumab, we investigated the expression of a disintegrin and metalloprotease 17 (ADAM17) in cancer tissues. ADAM17 has been involved in ovarian cancer development, progression and cell resistance to cisplatin. Tissue microarrays from 309 ovarian cancer patients enrolled in the MITO16A/MANGO-OV2 clinical trial were analyzed by immunohistochemistry for ADAM17 protein expression. Intensity and extent of staining were combined into a semi-quantitative visual grading system (H score) which was related to clinicopathological characteristics of cases and the clinical outcome of patients by univariate and multivariate Cox regression models. ADAM17 immunostaining was detected in most samples, mainly localized in the tumor cells, with variable intensity across the cohort. Kaplan–Meier survival curves, generated according to the best cut-off value for the ADAM17 H score, showed that high ADAM17 expression was associated with worse prognosis for PFS and OS. However, after the application of a shrinkage procedure to adjust for overfitting hazard ratio estimates, the ADAM17 value as prognostic factor was lost. As subgroup analysis suggested that ADAM17 expression could be prognostically relevant in cases with no residual disease at baseline, further studies in this patient category may be worth planning.

Objective: The aim of this study was to analyze the long-term toxicity and quality of life (QOL) in patients with locally advanced cervical cancer (LACC) treated with chemoradiation [chemotherapy/radiotherapy (CT/RT)] or neoadjuvant CT (NACT) followed by radical surgery (RS). Methods: Fifty-nine patients with LACC in remission after treatment with NACT + RS (n = 34) or CT/RT (n = 25) were interviewed with an Incontinence Impact Questionnaire (IIQ-7), a Quality of Life Questionnaire (EORTC QLQ-C30), and a Quality of Life Questionnaire for Cervical Cancer (EORTC QLQ-CX24) to compare long-term toxicity and QOL. Results: The mean age was 53 ± 9.8 and 59 ± 11.5 years in the NACT + RS and CT/RT groups, respectively. Overall, diarrhea and constipation were reported in 15 and 68%, respectively, while bladder complaints and a low level of sexual enjoyment were reported in 36 and 47%, respectively. The NACT + RS patients showed a worse sexual activity (74.71 ± 33.57 vs. 92.06 ± 17.96; p = 0.019) and sexual enjoyment (71.21 ± 23.67 vs. 88.88 ± 21.71; p = 0.040) and more frequently complained of constipation (49.01 ± 34.06 vs. 26.66 ± 31.66; p = 0.013), while CT/RT patients more frequently suffered from diarrhea (1.96 ± 7.96 vs. 14.66 ± 28.40; p = 0.017). Conclusions: Many patients treated for LACC have long-term complaints regarding sexual activity and bladder and bowel function. The majority of QOL aspects were similar in the two groups at long-term follow-up. However, diarrhea was more frequent and severe in CT/RT patients, while constipation was more frequent and severe in NACT + RS patients, and they showed a worse sexual life perception. Larger randomized trials addressing these issues are needed. © 2015 S. Karger AG, Basel [ABSTRACT FROM AUTHOR]

Homologous Recombination Deficiency (HRD) status predicts response to treatment with poly(ADP-ribose) polymerase inhibitors in Ovarian Cancer (OC) patients. The Myriad myChoiceCDx Assay is approved by Food and Drug Agency for the HRD assessment. Here we compared the HRD status obtained by three commercial panels with the results from Myriad reference test. The HRD analysis was performed on DNA from formalin-fixed and paraffin-embedded tumor samples of 100 untreated OC patients for which Myriad assay results were available, using TruSight Oncology 500 HRD assay (Illumina), Oncomine Comprehensive Assay Plus (Thermo Fisher Scientific) and SOPHiA DDM HRD solution panel (SOPHiA Genetics). A good overall concordance with the reference method was demonstrated at three different levels: BRCA mutational status (from 94.4 % to 97.7 %), the genomic instability value (from 88.2 % to 95.3 %) and for the HRD status (from 90.4 % to 97.6 %). Moreover, a trend in favour of HRD positive patients for response rate, progression-free survival and overall survival similar to Myriad was observed for all three tests. Our data suggest the feasibility of commercial testing for assessing HRD status, with a good concordance with the reference method and association with clinical outcome. • Harmonization of HRD assays is crucial for PARPi therapy in ovarian cancer. • HRD commercial assays have a good a good agreement rate with the reference test. • The commercial tests show a correlation with outcome similar to reference assay. • Discordance was observed in BRCA classification of variants. • Genomic instability scores close to cut-off should be discussed in the tumor board.

cemiplimab is an immunoglobulin G4 monoclonal antibody targeting the programmed cell death-1 receptor. A nominal use program is available in Italy in advanced cervical cancer (CC) patients treated with platinum based chemotherapy based on the results of EMPOWER-Cervical 1/GOG-3016/ENGOTcx9 trial. This real-world, retrospective cohort, multicenter study aimed at describing clinical outcomes of patients with advanced CC treated with cemiplimab in Italy. The primary objective of the study was to assess the feasibility and the replicability of the initial results in a real world setting of cemiplimab nominal use. The primary endpoint of our analysis was progression free survival (PFS). Secondary endpoints included overall response rate (ORR), overall survival (OS) and safety data. From March 2022 to December 2023, 135 patients were treated in 12 Multicenter Italian Trials in Ovarian cancer and gynecologic malignancies (MITO) Centers. Forty-two percent of patients had one or more comorbidities, hypertension being the most common (23.4%). Median PFS was 4.0 months (range 3.0–6.0) and median OS was 12.0 months (12.0- NR) with no differences according to PD-L1 status. Complete response (CR) or no evidence of disease (NED) were observed in 8.6%; partial response (PR) in 21.1%, stable disease (SD) in 14.8% and progression was recorded in 44.5% of patients. Most common drug related adverse events (AEs) were anemia (39.1%) and fatigue (27.8%). Immune related AEs occurred in 18.0%. This study confirms the feasibility and the replicability of the cemiplimab nominal use in advanced CC, in a real-world practice in Italy. • Cemiplimab is an immunoglobulin G4 monoclonal antibody targeting PD-L1. • A nominal use program of cemiplimab is available in Italy for cervical cancer. • MITO44 is a real-world, retrospective cohort, multicenter study. • MITO44 confirms the feasibility of the cemiplimab nominal use in cervical cancer. • PFS, ORR, OS and safety favorably compared to experimental data.

Simple Summary: Despite rapid progress in the research on epithelial ovarian cancer (EOC), it is usually diagnosed during the advanced stage with only 30% of patients surviving longer than 5 years. This is the first study in which the whole CXCR4-CXCL12-CXCR7 axis was systematically evaluated in tumor and stromal cells, through rigorous statistical methods in a prospective clinical trial. CXCL12 expression in cancer cells is associated with worse progression-free survival in stage III EOC patients, and deserves further attention as a potential prognostic and therapeutic target. This study investigated the prognostic role of the CXCR4-CXCL12-CXCR7 axis in advanced epithelial ovarian cancer (EOC) patients receiving first-line treatment within the MITO16A/MaNGO-OV2 phase-IV trial. CXCR4-CXCL12-CXCR7 expression was evaluated in the epithelial and stromal component of 308 EOC IHC-stained tumor samples. The statistical analysis focused on biomarkers' expression, their association with other variables and prognostic value. Zero-inflated tests, shrinkage, bootstrap procedures, and multivariable models were applied. The majority of EOC (75.0%) expressed CXCR4 and CXCR7, 56.5% expressed the entire CXCR4-CXCL12-CXCR7 axis, while only 4.6% were negative for CXCL12 and its cognate receptors, in regard to the epithelial component. Stromal CXCL12 and CXCR7, expressed in 11.2% and 65.5%, respectively, were associated with the FIGO stage. High CXCL12 in epithelial cancer cells was associated with shorter progression-free and overall survival. However, after adjusting for overfitting due to best cut-off multiplicity testing, the significance was lost. This is a wide-ranging, prospective study in which CXCR4-CXCL12-CXCR7 were systematically evaluated in epithelial and stromal components, in selected stage III-IV EOC. Although CXCL12 was not prognostic, epithelial expression identified high-risk FIGO stage III patients for PFS. These data suggest that it might be worth studying the CXCL12 axis as a therapeutic target to improve treatment efficacy in EOC patients. [ABSTRACT FROM AUTHOR]

The FEZ1/LZTS1 (FEZ1) gene maps to chromosome 8p22 and is frequently altered in human cancer. FEZ1 has been proposed as a candidate tumour suppressor gene and its loss may contribute to tumour progression. We have analysed the expression of FEZ1 protein in tissues from ovarian carcinomas in relation to clinico-pathological variables, response to chemotherapy and disease-free and overall survival. FEZ1 status was assessed by immunohistochemistry. Cytoplasmic staining for FEZ1 protein was absent or drastically reduced in 38% of tumours. FEZ1 protein expression was not related to tumour grade, histotype, disease-free survival, or overall survival. On the contrary, it was significantly correlated with age and with FIGO stage of disease. This finding indicates that FEZ1 is involved in ovarian carcinogenesis. Moreover, loss of FEZ1 protein significantly predicted a complete treatment response in patients who received taxane-based chemotherapy. In conclusion, the reduction or loss of FEZ1 protein could be an aid to the clinical management of patients affected by ovarian carcinoma. J. Cell.

Limited evidence exists to support CA-125 as a valid surrogate biomarker for progression in patients with ovarian cancer on maintenance PARP inhibitor (PARPi) therapy. We aimed to assess the concordance between CA-125 and Response Evaluation Criteria in Solid Tumours (RECIST) criteria for progression in patients with BRCA mutations on maintenance PARPi or placebo. We extracted data on progression as defined by Gynecologic Cancer InterGroup CA-125, investigator- and independent central-assessed RECIST from the SOLO2/ENGOT-ov21(NCT01874353) trial. We excluded those with progression other than by RECIST, progression on date of randomisation, and no repeat CA-125 beyond baseline. We evaluated the concordance between CA-125 progression and RECIST progression, and assessed the negative (NPV) and positive predictive value (PPV). Of 295 randomised patients, 275 (184 olaparib, 91 placebo) were included. 171 patients had investigator-assessed RECIST progression. Of 80 patients with CA-125 progression, 77 had concordant RECIST progression (PPV 96%, 95% confidence interval 90–99%). Of 195 patients without CA-125 progression, 94 had RECIST progression (NPV 52%, 45–59%). Within treatment arms, PPV was similar (olaparib: 95% [84–99%], placebo: 97% [87–100%]) but NPV was lower in patients on placebo (olaparib: 60% [52–68%], placebo: 30% [20–44%]). Of 94 patients with RECIST but without CA-125 progression, 64 (68%) had CA-125 that remained within normal range. We observed similar findings using independent-assessed RECIST. Almost half the patients without CA-125 progression had RECIST progression, and most of these had CA-125 within the normal range. Regular computed tomography imaging should be considered as part of surveillance in patients treated with or without maintenance olaparib rather than relying on CA-125 alone. • There is poor concordance between CA-125 non-PD and RECIST progression. • Half the patients without CA-125 PD had RECIST PD, most had normal CA-125 levels. • CT imaging to be considered as part of follow-up rather than relying on CA-125 alone.

Chemotherapy-induced neutropenia (CIN) has been associated with improved prognosis in several cancer conditions. Contrasting data have been produced in ovarian cancer. • Chemotherapy-induced neutropenia (CIN) has prognostic value in several cancer conditions. • Previously available data on CIN prognostic value in first line treatment of ovarian cancer are contrasting. • In two large MITO trials we found no significant prognostic value of CIN. • Lack of prognostic value of CIN in ovarian cancer was confirmed by meta-analyses with other published results. • This might derive from the use of AUC rather than BSA for dosing carboplatin, a key drug in this setting.

Cervical cancer cells often express Epidermal Growth Factor Receptor (EGFR). Cetuximab (CET), an anti-EGFR antibody, can be safely combined with carboplatin (C) and paclitaxel (P), a standard treatment for advanced/recurrent cervical cancer (ARCC) patients. ARCC patients, ECOG PS ≤ 1, were randomized to CP for 6 cycles with or without CET (400 mg/m2 one week before starting CP, then 250 mg/m2 weekly) until disease progression or unacceptable toxicity. Event-free survival (EFS) was the primary endpoint. With a 4.5 months expected median EFS and a 6.4 months predicted EFS (HR 0.70), 0.20 one-tailed α and 80% power, 89 events were required for the final intent-to-treat analysis. 108 patients were assigned to CP (n = 53) or CP-CET (n = 55). Median age was 50, 69% were PS0, 76% had recurrent disease, 91% had distant metastasis and 57% had received previous chemotherapy. After a median follow-up of 23 months, 102 patients had an event, 97 progressed and 61 died. Median EFS was 4.7 and 6.0 months (one-tail P = 0.43), median PFS was 5.2 and 7.6 months (one-tail P = 0.20) and median OS was 17.7 and 17 months (one-tail P = 0.27), with CP and CP-CET, respectively. There was no difference in the occurrence of severe adverse events, except for skin toxicity. Biomarker analysis, in a small subgroup of patients, suggests that PIK3CA mutation might be predictive of CET resistance. CP-CET was not more active than CP alone in unselected ARCC patients. • Cervical cancer cells often express the epidermal growth factor receptor (EGFR). • However, the addition of cetuximab to chemotherapy did not produce benefit for advanced/recurrent cervical cancer patients. • The presence of PIK3CA mutations may be associated with resistance to cetuximab treatment.

Abstract Objective To compare clinical outcomes of patients diagnosed with low-risk gestational trophoblastic neoplasia (GTN) receiving intramuscular methotrexate 50 mg total dose/day versus 1 mg/kg/day in a 8-day methotrexate/folinic acid (MTX/FA) regimen. Methods This retrospective, multicenter study included 176 patients: 99 (56%) receiving methotrexate 50 mg total dose/day on days 1, 3, 5, 7 alternated with FA 7,5 mg on days 2, 4, 6, 8, every 14 days (group A); and 77 patients (44%), receiving methotrexate 1 mg/kg/day on days 1, 3, 5, 7 alternated with FA 7,5 mg on days 2, 4, 6, 8, every 14 days (group B). Patients' characteristics and outcomes were compared by univariate analysis. Results Forty-five patients (25.6%) developed resistance to MTX and received a second-line treatment, 7 (4%) received a third-line treatment and 8 (4.5%) relapsed after initial remission. There was no difference between group A and B patients in the average number of chemotherapy cycles required to achieve remission (5.7 ± 2.6 vs 6.3 ± 2.3, p = 0.106). The 2 treatment groups showed comparable rates of MTX resistance (28.3% vs 22.1%, p = 0.387) and relapse (3% vs 6.5%, p = 0.300). There was no difference in the incidence of treatment toxicity of any CTCAE grade between group A and B patients (16.2% vs 15.2%, p = 0.999). Subgroup analysis stratifying patients by weight (<50 kg, ≥60 kg, ≥70 kg, ≥80 kg) confirmed these results. Conclusion The 2 MTX schedules showed comparable efficacy in the treatment of low-risk GTN with an acceptable rate of toxicity. Highlights • Resistance and relapse rates of patients treated with MTX 50 mg/day versus 1 mg/kg/day in a 8-day MTX-FA regimen are similar. • Average number of chemotherapy cycles required to achieve disease remission is the same, with comparable toxicity. • Patient stratification by body weight does not highlight significant differences between the 2 regimens.

Summary Background Inhibition of angiogenesis is a valuable treatment strategy for ovarian cancer. Pazopanib is an anti-angiogenic drug active in ovarian cancer. We assessed the effect of adding pazopanib to paclitaxel for patients with platinum-resistant or platinum-refractory advanced ovarian cancer. Methods We did this open-label, randomised phase 2 trial at 11 hospitals in Italy. We included patients with platinum-resistant or platinum-refractory ovarian cancer previously treated with a maximum of two lines of chemotherapy, Eastern Cooperative Oncology Group performance status 0–1, and no residual peripheral neurotoxicity. Patients were randomly assigned (1:1) to receive weekly paclitaxel 80 mg/m 2 with or without pazopanib 800 mg daily, and stratified by centre, number of previous lines of chemotherapy, and platinum-free interval status. The primary endpoint was progression-free survival, assessed in the modified intention-to-treat population. This trial is registered with ClinicalTrials.gov , number NCT01644825 . This report is the final analysis; the trial is completed. Findings Between Dec 15, 2010, and Feb 8, 2013, we enrolled 74 patients: 37 were randomly assigned to receive paclitaxel and pazopanib and 37 were randomly assigned to receive paclitaxel only. One patient, in the paclitaxel only group, withdrew from the study and was excluded from analyses. Median follow-up was 16·1 months (IQR 12·5–20·8). Progression-free survival was significantly longer in the pazopanib plus paclitaxel group than in the paclitaxel only group (median 6·35 months [95% CI 5·36–11·02] vs 3·49 months [2·01–5·66]; hazard ratio 0·42 [95% CI 0·25–0·69]; p=0·0002). We recorded no unexpected toxic effects or deaths from toxic effects. Adverse events were more common in the pazopanib and paclitaxel group than in the paclitaxel only group. The most common grade 3–4 adverse events were neutropenia (11 [30%] in the pazopanib group vs one [3%] in the paclitaxel group), fatigue (four [11%] vs two [6%]), leucopenia (four [11%] vs one [3%]), hypertension (three [8%] vs none [0%]), raised aspartate aminotransferase or alanine aminotransferase (three [8%] vs none), and anaemia (two [5%] vs five [14%]). One patient in the pazopanib group had ileal perforation. Interpretation Our findings suggest that a phase 3 study of the combination of weekly paclitaxel plus pazopanib for patients with platinum-resistant or platinum-refractory advanced ovarian cancer is warranted.

Background Analysis of progression-free survival (PFS) as the primary endpoint in advanced epithelial ovarian, fallopian tube, and primary peritoneal cancer (AEOC) trials may be confounded by the difficulty of radiologic evaluation of disease progression and the potential for discrepancy between investigator and blinded independent central assessments. PFS as assessed by local investigator (INV) was the primary endpoint of AGO-OVAR16, a randomized, double-blind trial of pazopanib maintenance therapy in AEOC. To confirm the robustness of the primary analysis, PFS was also evaluated by blinded independent central review (BICR). Methods Patients with histologically confirmed AEOC (N = 940) were randomized 1:1 to receive pazopanib 800 mg/day or placebo for up to 24 months. Tumor response in the intent-to-treat population was evaluated by CT/MRI every 6 months and analyzed per RECIST 1.0. Results Pazopanib prolonged PFS versus placebo by INV (median 17.9 vs 12.3 months; hazard ratio [HR] = 0.766, 95% confidence interval [CI]: 0.643-0.911; P = 0.0021). Results for PFS by BICR were similar (median 15.4 vs 11.8 months; HR = 0.802, 95% CI: 0.678-0.949; P = 0.0084). Progression events were recorded later by INV in 23% of pazopanib-treated patients and 17% of placebo-treated patients. The overall concordance between INV and BICR assessments was 84% and 86% in the pazopanib and placebo arms, respectively. Conclusions By INV and BICR assessments, maintenance therapy with pazopanib in AEOC provided a significantly longer PFS than placebo. The good overall concordance between INV and BICR assessments, as well as HR and P value consistency, supports the reliability of investigator-assessed PFS as the primary endpoint in AGO-OVAR16.

Background and Aims: Ovarian clear cell carcinoma (CCC) has a poorer prognosis than other subtypes of ovarian cancer. In this study, we evaluated the responsiveness to second-line chemotherapy in recurrent ovarian CCC. Methods: The MITO-9 project investigated a cohort of patients observed between 1991 and 2007 in 20 centers. We identified 72 out of 240 patients with recurrent disease (28% stage I-II and 72% stage III-IV at diagnosis). Results: In 56% of patients, the clear cell histology was pure. Twenty-five patients were platinum-resistant, 18 were platinum-sensitive with a platinum-free interval (PFI) of 6-12 months, and 29 had a PFI >12 months. Upon recurrence, 47% of patients were treated with platinum chemotherapy according to the PFI. The overall response rate (RR) to platinum was 80%, with 55, 100, and 80% RR in patients with PFI of 6-12, >12, and >24 months. The RR to nonplatinum agents in resistant patients was 33%. Among the nonplatinum agents used in primary and secondary resistant cases, gemcitabine, administered in 12 cases, had a higher activity (RR = 66%) compared to topotecan or liposomal doxorubicin (n = 31; RR = 33 and 10%, respectively). Conclusions: This study showed that the treatment of recurrent ovarian CCC should be based on the PFI as in the other subtypes. Data in platinum-resistant patients suggest gemcitabine as the drug with the highest activity. We recommend that gemcitabine be studied prospectively in a phase 2 trial. © 2014 S.

Abstract: Epithelial ovarian cancer is the most common type of ovarian cancer; usually occurs in women older than 50years, and because 75% of cases are diagnosed at stage III or IV it is associated with a poor prognosis. Treatment of ovarian cancer is based on the integration of surgery and chemotherapy. Chemotherapy plays a major role both in the adjuvant treatment and in the care of patients with advanced disease. Several active drugs have been introduced in the treatment of ovarian cancer in the last decades and novel targets and agents are under evaluation. [Copyright &y& Elsevier]

Abstract: Objective: Many questions remain unanswered regarding the optimal treatment paradigm for ovarian cancer, and alternatives for both first- and second-line therapy are needed. Methods: This review summarizes recent data with the combination of pegylated liposomal doxorubicin (PLD) and carboplatin in ovarian cancer. Results: Anthracyclines are active in ovarian cancer and lack the neurotoxic effects of taxanes. PLD has reduced cardiotoxic potential vs non-liposomal doxorubicin and is the only non-platinum monotherapy to demonstrate a significant survival advantage as second-line treatment of ovarian cancer. Replacing the taxane with PLD in platinum doublets for either first-line or recurrent ovarian cancer (ROC) has been or is being evaluated in more than 1600 patients. Studies evaluating PLD plus carboplatin in platinum-sensitive ROC have shown that the regimen is tolerable and active. Conclusion: PLD–carboplatin is a promising chemotherapy combination. Phase III trials will elucidate whether it represents a new standard of care in ovarian cancer. [Copyright &y& Elsevier]

Abstract: Background: Carboplatin/paclitaxel every 3 weeks is the standard for patients with ovarian cancer, but elderly patients frequently receive modified schedules or single agent chemotherapy to avoid toxicity. A phase II study was conducted to describe tolerability of a weekly schedule of both drugs in elderly patients. Methods: Patients aged ≥70 years with stage IC-IV ovarian cancer, performance status ≤2, were eligible. Treatment was carboplatin (AUC 2)+paclitaxel (60mg/m2) on days 1, 8, 15 every 4 weeks, up to six cycles. A two-stage design was applied with lack of unacceptable toxicity as primary endpoint; 26 patients were required at the final stage, with at least 23 of them without unacceptable toxicity to conclude for a positive result. Geriatric assessment was performed by activity daily living (ADL) and instrumental ADL (IADL) scales. Results: Twenty-six patients were analysed (median age 77 years, range 70–84). Performance status was 0 in 10 and 1 in 16 patients; 14 patients had two or more comorbidities; 8 and 18 patients had some dependency in ADL or IADL. Twenty-three patients (88.5%) were treated without suffering unacceptable toxicity. Unacceptable toxic events were grade 3 heart rhythm, grade 3 increase of liver transaminases and prolonged haematological toxicity. Grade 1 neuropathy was reported in four cases. Out of 13 patients evaluable by RECIST, 5 partial responses were observed (response rate 38.5%). Two complete responses were observed among six patients with non-target lesions. Eight patients eligible for CA-125 response assessment had a response after six cycles. Median estimated progression-free survival was 13.6 months, and median overall survival was 32.0 months. Conclusions: In a series of elderly ovarian cancer patients, characterized by a high incidence of comorbidities and functional impairment, weekly carboplatin and paclitaxel demonstrated a favourable toxicity profile.

Background: The MITO-2 (Multicentre Italian Trials in Ovarian cancer) study is a randomized phase III trial comparing carboplatin plus paclitaxel to carboplatin plus pegylated liposomal doxorubicin in first-line chemotherapy of patients with ovarian cancer. Due to the paucity of published phase I data on the 3-weekly experimental schedule used, an early safety analysis was planned. Methods: Patients with ovarian cancer (stage Ic-IV), aged < 75 years, ECOG performance status = 2, were randomized to carboplatin AUC 5 plus paclitaxel 175 mg/m2, every 3 weeks or to carboplatin AUC 5 plus pegylated liposomal doxorubicin 30 mg/m2, every 3 weeks. Treatment was planned for 6 cycles. Toxicity was coded according to the NCI-CTC version 2.0. Results: The pre-planned safety analysis was performed in July 2004. Data from the first 50 patients treated with carboplatin plus pegylated liposomal doxorubicin were evaluated. Median age was 60 years (range 34-75). Forty-three patients (86%) completed 6 cycles. Two thirds of the patients had at least one cycle delayed due to toxicity, but 63% of the cycles were administered on time. In most cases the reason for chemotherapy delay was neutropenia or other hematological toxicity. No delay due to palmar-plantar erythrodysesthesia (PPE) was recorded. No toxic death was recorded. Reported hematological toxicities were: grade (G) 3 anemia 16%, G3/ G4 neutropenia 36% and 10% respectively, G3/4 thrombocytopenia 22% and 4% respectively. Non-haematological toxicity was infrequent: pulmonary G1 6%, heart rhythm G1 4%, liver toxicity G1 6%, G2 4% and G3 2%. Complete hair loss was reported in 6% of patients, and G1 neuropathy in 2%. PPE was recorded in 14% of the cases (G1 10%, G2 2%, G3 2%). Conclusion: This safety analysis shows that the adopted schedule of carboplatin plus pegylated liposomal doxorubicin given every 3 weeks is feasible as first line treatment in ovarian cancer patients, although 37% of the cycles were delayed due to haematological toxicity. Toxicities that are common with standard combination of carboplatin plus paclitaxel (neurotoxicity and hair loss) are infrequent with this experimental schedule, and skin toxicity appears manageable.

Background: Carboplatin/paclitaxel is the chemotherapy of choice for advanced ovarian cancer, both in first line and in platinum-sensitive recurrence. Although a significant proportion of patients have some neurotoxicity during treatment, the long-term outcome of chemotherapy-induced neuropathy has been scantly studied. We retrospectively assessed the prevalence of residual neuropathy in a cohort of patients in clinical remission after first-line carboplatin/paclitaxel for advanced ovarian cancer. Methods: 120 patients have been included in this study (101 participating in a multicentre phase III trial evaluating the efficacy of consolidation treatment with topotecan, and 19 treated at the National Cancer Institute of Naples after the end of the trial). All patients received carboplatin (AUC 5) plus paclitaxel (175 mg/m2) every 3 weeks for 6 cycles, completing treatment between 1998 and 2003. Data were collected between May and September 2004. Residual sensory and motor neurotoxicity were coded according to the National Cancer Institute — Common Toxicity Criteria. Results: 55 patients (46%) did not experience any grade of neurological toxicity during chemotherapy and of these none had signs of neuropathy during follow-up. The other 65 patients (54%) had chemotherapy-induced neurotoxicity during treatment and follow-up data are available for 60 of them. Fourteen out of 60 patients (23%) referred residual neuropathy at the most recent follow-up visit, after a median follow up of 18 months (range, 7-58 months): 12 patients had grade 1 and 2 patients grade 2 peripheral sensory neuropathy; 3 patients also had grade 1 motor neuropathy. The remaining 46/60 patients (77%) had no residual neuropathy at the moment of interview: recovery from neurotoxicity had occurred in the first 2 months after the end of chemotherapy in 22 (37%), between 2 and 6 months in 15 (25%), or after more than 6 months in 9 patients (15%). Considering all 120 treated patients, there was a 15% probability of persistent neurological toxicity 6 months after the end of chemotherapy. Conclusion: A significant proportion of patients with advanced ovarian cancer treated with firstline carboplatin/paclitaxel suffer long-term residual neuropathy. This issue should be carefully taken into account before considering re-treatment with the same agents in sensitive recurrent disease. [ABSTRACT FROM AUTHOR]

Friedreich's ataxia is a recessive neurodegenerative disease due to insufficient expression of the mitochondnal protein frataxin. Although it has been shown that frataxin is involved in the control of intracellular iron metabolism, by interfering with the mitochondrial biosynthesis of proteins with iron/sulphur (Fe/S) clusters its role has not been well established. We studied frataxin protein and mRNA expression and localisation during cellular differentiation. We used the human colon adenocarcinoma cell line Caco- 2, as it is considered a good model for intestinal epithelial differentiation and the study of intestinal iron metabolism. Here we report that the protein, but not the mRNA frataxin levels, increase during the enterocyte-like differentiation of Caco-2 cells, as well as in in-vivo-differentiated enterocytes at the upper half of the crypt-villus axis. Furthermore, sub cellular fractionation and double imrnunostaining, followed by confocal analysis, reveal that frataxin localisation changes during Caco-2 cell differentiation. In particular, we found an extramitochondrial localisation of frataxin in differentiated cells. Finally, we demonstrate a physical interaction between extramitochondrial frataxin and IscU1, a cytoplasmic isoform of the human Fe/S cluster assembly machinery. Based on our data, we postulate that frataxin could be involved in the biosynthesis of irons sulphur proteins not only within the mitochondria, but also in the extramitochondrial compartment. These findings might be of relevance for the understanding of both the pathogenesis of Friedreich's ataxia and the basic mechanism of Fe/S cluster biosynthesis. [ABSTRACT FROM AUTHOR]

Purpose: To review the content and quality of prospective clinical trials of biotherapies in solid tumors. Methods: Data were collected from the literature between 1990 and 2002 on general study characteristics, patient and disease factors, study methodology, and factors related to completeness of reporting. Quality of phase II studies was evaluated by an ad hoc questionnaire. Descriptive statistics, contingency tables, and the ?-square test were applied. Results: A total of 334 studies were selected, of which about three quarters were multicenter, with 42.5% reporting phase I, 42.2% phase II or I/II, and 11.9% phase III or II/III studies. Only 13.7% were randomized, and a study design emphasizing statistical analysis was lacking in as many as one third. The assessment of biological endpoints was stated as the primary or secondary goal in half of these studies. Melanoma (17.1%), renal carcinoma (11.1%), gastrointestinal neoplasms (11.1%), and lymphomas (6.3%) were the most studied diseases. Immunotherapies accounted for 182 studies; the remaining 152 reported other biotherapies. Patients with (1) advanced disease (P=0.003), (2) heavily pretreated neoplasms (P<0.0001), (3) poor performance status (PS<2) (P<0.0001), were more frequently enrolled in studies of biotherapy. Biotherapies were less frequently evaluated in phase III studies (7/152) compared with immunotherapies (33/182) (P<0.0001). A statistical study design was more frequently identified in biotherapy trials (127/152) compared with immunotherapy trials (98/182) (P<0.0001). Biological endpoints were less frequently evaluated in phase III studies in both biotherapies (100% no vs 0% yes) and immunotherapies (81.8% no vs 18.2% yes) (P=0.01, for biotherapies;P<0.0001, for immunotherapies). Phase I immunotherapy studies more frequently applied biological or molecular criteria for patient selection (41.1%) than phase II (29.3%) and III (3.1%) studies (P<0.0001). Conclusions: The very wide diversity in modalities of conducting and reporting clinical trials of biotherapies of solid tumors and the presence of some methodological pitfalls suggest that the methodological standards for conducting and publishing clinical trials in biotherapies should be improved to enhance the reliability of the body of published data.

Cervical cancer is among the major health problems world-wide although advances in screening programs. Surgery and radiotherapy are the treatment modalities of choice for early and locally advanced cervical cancer. However, the role of chemotherapy in this setting has been better investigated in the latest years. To improve loco-regional control in locally advanced disease, authors have tested both neo-adjuvant chemotherapy and concurrent chemoradiotherapy. From 1999 NCI clinical announcement, concurrent cisplatin-based chemoradiation is considered the treatment of choice for cervical cancer patients requiring radiation therapy. Neo-adjuvant chemotherapy is reaching encouraging results in IB bulky-IIA cervical cancer, but further investigation are ongoing in locally advanced cervical setting. The optimal treatment for patients with metastatic or recurrent cervical cancer is still undefined and chemotherapy is used with palliation intent. Cisplatin remains the most active cytotoxic agents, although combinations of cisplatin with paclitaxel, topotecan, vinorelbine, have shown encouraging results in phase II and in early phase III studies. This paper reviews the role of chemotherapy in the management of patients with locally advanced, metastatic and recurrent cervical cancer. Studies discussed in this paper were selected trough a search in the med-line database performed in October 2003. [Copyright &y& Elsevier]
