Objective: To report the safety and efficacy results of patients enrolled in the Italian Nivolumab Renal Cell Cancer Expanded Access Programme. Patients and Methods: Patients with metastatic renal cell cancer (mRCC) previously treated with agents targeting the vascular endothelial growth factor pathway were eligible to receive nivolumab 3 mg/kg once every 2 weeks. Patients included in the analysis had received ≥1 dose of nivolumab and were monitored for adverse events (AEs) using Common Terminology Criteria for Adverse Events (CTCAE) v.4.0. Results: A total of 389 patients were enrolled between July 2015 and April 2016, of whom 18% were aged ≥75 years, 6.7% had non-clear cell RCC, 49.6% had bone and 8.2% brain metastases, and 79% had received ≥2 previous lines of therapy. The most common any-grade treatment-related AEs were fatigue (13%) and rash (9%). Twenty-two patients (5.7%) discontinued treatment because of AEs. There were no treatment-related deaths. The objective response rate was 23.1%. At a median follow-up of 12 months, the median progression-free survival was 4.5 months (95% confidence interval 3.7–6.2) and the 12-month overall survival rate was 63%. Similar survival rates were reported among patients with non-clear-cell histology, elderly patients, those with bone and/or brain metastases, and those who had received prior first-line sunitinib or pazopanib, or prior everolimus. Conclusion: The safety and efficacy observed were consistent with those reported in the pivotal Checkmate 025 trial. Results in patients with non-clear-cell mRCC who were elderly, pretreated with everolimus, and had bone and/or brain metastases encourage the use of nivolumab in these categories of patients. © 2018 The Authors BJU International

PubMed ID: 12829583, Several studies have compared bone marrow (BM) and peripheral blood (PB) as stem cell sources in patients receiving allografts, but the cell doses infused have not been considered, especially for BM. Using the ALWP/EBMT registry, we retrospectively studied 881 adult patients with acute myelocytic leukemia (AML), who received a non-T-depleted allogeneic BM (n = 515) or mobilized PB (n = 366) standard transplant, in first remission (CR1), from an HLA-identical sibling, over a 5-year period from January 1994. The BM cell dose ranged from 0.17 to 29 × 10 8 /kg with a median of 2.7 × 10 8 /kg. The PB cell dose ranged from 0.02 to 77 × 10 8 /kg with a median of 9.3 × 10 8 /kg. The median dose for patients receiving BM (2.7 × 10 8 /kg) gave the greatest discrimination. In multivariate analyses, high-dose BM compared to PB was associated with lower transplant-related mortality (RR = 0.61; 95% CI, 0.39-0.98; P = .04), better leukemia-free survival (RR = 0.65; 95% CI, 0.46-0.91; P = .013), and better overall survival (RR = 0.64; 95% CI, 0.44-0. 92; P = .016). The present study in patients with AML receiving allografts in first remission indicates a better outcome with BM as compared to PB, when the dose of BM infused is rich. © 2003 by The American Society of Hematology.

The transplantation of mobilised peripheral progenitor cells has resulted in shortening of neutrophil and platelet engrafment times following high-dose chemotherapy. Since reticulated platelet percentage (PR%) has been established as a measure of bone marrow platelet production, we performed this type of analysis on the thrombopoietic compartment during transplant-related chemotherapy.Kinetics of thrombopoiesis of 19 patients with solid tumors undergoing a single or double autologous peripheral blood progenitor cell transplant was characterized by evaluating the level of RP. The correlation between CD34(+) cell subsets and the time of highest percentage of RP was also evaluated.The percentage of RP increases since day +8 after single transplant reaching the peak (3.4%) at day +10. In the group of patients receiving double transplant, the RP value of peak observed after second transplant is not significantly different from that one observed after the first transplant (3 vs 3.7%). In a subgroup of patients both the number of CD34(+) cells/Kg infused and the percentage of CD34(+) CD61(+) cell subsets correlate with the day of RP peak.These results suggest that RP measurement is an early indicator of engraftment. Additionally, the observation that RP percentage is high at the time of platelet transfusion in 13 out of 20 cases of transfusions (the 7 cases with low RP value being transfused during the period of obligate thrombocytopenia) suggests that the evaluation of this parameter, together with the platelet count, can be used to monitor the need for platelet transfusion.

Doxorubicin/paclitaxel (Taxol) combinations are very active in advanced breast cancer, with objective response rates up to 90%, but have shown a high incidence of cardiotoxicity. A phase I/II trial replacing doxorubicin with epirubicin (Ellence), a less cardiotoxic analog, produced an objective response rate of 84%, but with a low rate of cardiotoxicity. A careful cardiac monitoring in more than 100 patients treated with this combination has demonstrated that the risk of congestive heart failure is below 10% up to a cumulative epirubicin dose of 990 mg/m2. To examine the possibility that the pharmacokinetic and pharmacodynamic interactions that occur when anthracycline and paclitaxel are administered together might result in subadditive antitumor activity, a phase III study is comparing concomitant vs sequential administration of epirubicin and paclitaxel in patients with advanced breast cancer. A phase I/II study of epirubicin plus docetaxel as first-line chemotherapy for advanced breast cancer patients evaluated the maximum tolerated doses and for subsequent studies recommended epirubicin at 75 mg/m2 plus docetaxel at 80 mg/m2. In the adjuvant setting, an ongoing phase III trial is comparing epirubicin plus paclitaxel vs FEC (fluorouracil, epirubicin, and cyclophosphamide [Cytoxan, Neosar]) in node-positive patients. Preliminary data confirm the cardiac safety of these treatments.

Several trials have shown that anthracyclines and taxanes can be combined to achieve response rates ranging from 70% to 90%, with complete responses ranging from 19% to 41%. In an attempt to increase the activity while maintaining tolerability, gemcitabine (Gemzar) was added to the epirubicin (Ellence)/paclitaxel (Taxol) regimen. Among 36 metastatic breast cancer patients treated with this new combination, the overall response rate was 92%, including 31% with a complete response. Another attempt to improve the outcome of metastatic breast cancer patients involves a phase III multicentric randomized trial (MANTA-1) to evaluate if paclitaxel maintenance therapy after anthracycline/taxane combination therapy can improve time to progression and overall survival. Although anthracyclines are more frequently used in the adjuvant setting, it is important for the clinicians to know whether this class of drugs can be used again for those patients who develop metastatic disease. An analysis of 312 patients treated with epirubicin containing regimens as first-line treatment for metastatic disease shows that epirubicin-based regimens are active in patients already exposed to anthracyclines in the adjuvant setting, and that the risk of cardiac toxicity is low up to a cumulative epirubicin dose of 990 mg/m2.

This phase I-II study aimed to determine the maximum tolerated dose (MTD) of paclitaxel (Taxol), infused over 3 hours, when combined with a fixed dose (90 mg/m2) of epirubicin. Other aims were to investigate the combination's plasma pharmacokinetics, toxicity, and activity in 50 patients with previously untreated metastatic breast cancer, as well as its ability to mobilize peripheral blood stem cells (PBSCs). The initial dose of paclitaxel, 135 mg/m2, was increased by 20 mg/m2 in subsequent cohorts of six patients until dose-limiting toxicity (DLT) occurred. The DLT of the combination was febrile neutropenia in two of eight patients who received paclitaxel at 225 mg/m2. The concentration of epirubicinol, the major metabolite of epirubicin, decreased from 47.3 +/- 9.4 ng/mL at 175 mg/m2 of paclitaxel to 37.9 +/- 7.5 ng/mL at the 225-mg/m2 dose. The most relevant toxicity was grade 4 neutropenia (61% of all the courses). Cardiac toxicity included three patients (6%) developing congestive heart failure responsive to therapy. Among 49 evaluable patients, 41 responses (84%) were observed (95% confidence interval [CI], 70% to 92%) and 9 (19%) of these were complete. In 21 patients, we evaluated the mobilization of PBSCs after this regimen plus a colony-stimulating factor. The median number of CD34+ cells was 61.7/microL (range, 6.8 to 201/microL), and a median of 6.3 x 10(6)/kg of CD34+ cells have been harvested with a single leukapheresis.

Summary Background The triplet FOLFOXIRI (fluorouracil, leucovorin, oxaliplatin, and irinotecan) plus bevacizumab showed improved outcomes for patients with metastatic colorectal cancer, compared with FOLFIRI (fluorouracil, leucovorin, and irinotecan) plus bevacizumab. However, the actual benefit of the upfront exposure to the three cytotoxic drugs compared with a preplanned sequential strategy of doublets was not clear, and neither was the feasibility or efficacy of therapies after disease progression. We aimed to compare a preplanned strategy of upfront FOLFOXIRI followed by the reintroduction of the same regimen after disease progression versus a sequence of mFOLFOX6 (fluorouracil, leucovorin, and oxaliplatin) and FOLFIRI doublets, in combination with bevacizumab. Methods TRIBE2 was an open-label, phase 3, randomised study of patients aged 18–75 years with an Eastern Cooperative Oncology Group (ECOG) performance status of 2, with unresectable, previously untreated metastatic colorectal cancer, recruited from 58 Italian oncology units. Patients were stratified according to centre, ECOG performance status, primary tumour location, and previous adjuvant chemotherapy. A randomisation system incorporating a minimisation algorithm was used to randomly assign patients (1:1) via a masked web-based allocation procedure to two different treatment strategies. In the control group, patients received first-line mFOLFOX6 (85 mg/m2 of intravenous oxaliplatin concurrently with 200 mg/m2 of leucovorin over 120 min; 400 mg/m2 intravenous bolus of fluorouracil; 2400 mg/m2 continuous infusion of fluorouracil for 48 h) plus bevacizumab (5 mg/kg intravenously over 30 min) followed by FOLFIRI (180 mg/m2 of intravenous irinotecan over 120 min concurrently with 200 mg/m2 of leucovorin; 400 mg/m2 intravenous bolus of fluorouracil; 2400 mg/m2 continuous infusion of fluorouracil for 48 h) plus bevacizumab after disease progression. In the experimental group, patients received FOLFOXIRI (165 mg/m2 of intravenous irinotecan over 60 min; 85 mg/m2 intravenous oxaliplatin concurrently with 200 mg/m2 of leucovorin over 120 min; 3200 mg/m2 continuous infusion of fluorouracil for 48 h) plus bevacizumab followed by the reintroduction of the same regimen after disease progression. Combination treatments were repeated every 14 days for up to eight cycles followed by fluorouracil and leucovorin (at the same dose administered at the last induction cycle) plus bevacizumab maintenance until disease progression, unacceptable adverse events, or consent withdrawal. Patients and investigators were not masked. The primary endpoint was progression-free survival 2, defined as the time from randomisation to disease progression on any treatment given after first disease progression, or death, analysed by intention to treat. Safety was assessed in patients who received at least one dose of their assigned treatment. Study recruitment is complete and follow-up is ongoing. This trial is registered with Clinicaltrials.gov , NCT02339116 . Findings Between Feb 26, 2015, and May 15, 2017, 679 patients were randomly assigned and received treatment (340 in the control group and 339 in the experimental group). At data cut-off (July 30, 2019) median follow-up was 35·9 months (IQR 30·1–41·4). Median progression-free survival 2 was 19·2 months (95% CI 17·3–21·4) in the experimental group and 16·4 months (15·1–17·5) in the control group (hazard ratio [HR] 0·74, 95% CI 0·63–0·88; p=0·0005). During the first-line treatment, the most frequent of all-cause grade 3–4 events were diarrhoea (57 [17%] vs 18 [5%]), neutropenia (168 [50%] vs 71 [21%]), and arterial hypertension (25 [7%] vs 35 [10%]) in the experimental group compared with the control group. Serious adverse events occurred in 84 (25%) patients in the experimental group and in 56 (17%) patients in the control group. Eight treatment-related deaths were reported in the experimental group (two intestinal occlusions, two intestinal perforations, two sepsis, one myocardial infarction, and one bleeding) and four in the control group (two occlusions, one perforation, and one pulmonary embolism). After first disease progression, no substantial differences in the incidence of grade 3 or 4 adverse events were reported between the control and experimental groups, with the exception of neurotoxicity, which was only reported in the experimental group (six [5%] of 132 patients). Serious adverse events after disease progression occurred in 20 (15%) patients in the experimental group and 25 (12%) in the control group. Three treatment-related deaths after first disease progression were reported in the experimental group (two intestinal occlusions and one sepsis) and four in the control group (one intestinal occlusion, one intestinal perforation, one cerebrovascular event, and one sepsis). Interpretation Upfront FOLFOXIRI plus bevacizumab followed by the reintroduction of the same regimen after disease progression seems to be a preferable therapeutic strategy to sequential administration of chemotherapy doublets, in combination with bevacizumab, for patients with metastatic colorectal cancer selected according to the study criteria.

Objectives: Never-smokers may be a distinct subgroup among patients with advanced non-small cell lung cancer, appearing to benefit less from immunotherapy than smokers. We report results from never-smokers enrolled in the Italian cohort of the nivolumab expanded access program in pre-treated patients with advanced squamous non-small cell lung cancer. Materials and methods: Nivolumab (3 mg/kg every 2 weeks for ≤24 months) was available on physician request. Efficacy data included objective tumor response, date of progression, and survival information. Safety was monitored. Results: Overall, 371 patients received at least one dose of nivolumab, including 31 never-smokers (8%). Objective response rate, disease-control rate, and median overall survival were 23%, 45%, and 12.1 months (95% confidence interval: 3.7–20.4), respectively, in never-smokers, and 18%, 47%, and 7.9 months (95% confidence interval: 6.2–9.6), respectively, in the overall expanded access program population. Any-grade and grade 3–4 treatment-related adverse events were reported in 12 (39%) and 3 (10%) never-smokers, respectively, and in 109 (29%) and 21 (6%) patients, respectively, in the overall expanded access program population. Grade 3–4 treatment-related adverse events in non-smokers were increased transaminases (n = 2; 6%) and diarrhea (n = 1; 3%). Treatment-related adverse events led to treatment discontinuation in 4 non-smokers (17%) and in 26 patients (9%) overall. Conclusion: Pre-treated never-smokers with advanced squamous non-small cell lung cancer in this Italian expanded access program demonstrated efficacy and safety that were consistent with those in the overall expanded access program population and clinical trials. These results suggest that a proportion of never-smoker patients with squamous non-small cell lung cancer may be responsive to immunotherapy. Other factors, such as the tumor mutational load and the status of programmed death-ligand 1, anaplastic lymphoma kinase, and epidermal growth factor receptor, might play a potential key role.

The aim of this retrospective study was to assess toxicity and efficacy of adjuvant high-dose chemotherapy (HDC) and autologous hematopoietic stem cell transplantation (AHSCT) in 583 high-risk breast cancer (BC) patients (>3 positive nodes) who were transplanted between 1995 and 2005 in Europe. All patients received surgery before transplant, and 55 patients (9.5%) received neoadjuvant treatment before surgery. Median age was 47.1 years, 57.3% of patients were premenopausal at treatment, 56.5% had endocrine-responsive tumors, 19.5% had a human epidermal growth factor receptor 2 (HER2)-negative tumor, and 72.4% had >= 10 positive lymph nodes at surgery. Seventy-nine percent received a single HDC procedure. Overall transplant-related mortality was 1.9%, at .9% between 2001 and 2005, whereas secondary tumor-related mortality was .9%. With a median follow-up of 120 months, overall survival and disease-free survival rates at 5 and 10 years in the whole population were 75% and 64% and 58% and 44%, respectively. Subgroup analysis demonstrated that rates of overall survival were significantly better in patients with endocrine-responsive tumors

Introduction Nivolumab is the first checkpoint inhibitor approved for the treatment of nonsquamous NSCLC. We report results from the nivolumab Italian expanded access program focusing on never-smokers and patients with EGFR-mutant nonsqamous NSCLC. Methods Nivolumab (3 mg/kg intravenously every 2 weeks) was administered upon physicians' request to patients who had relapsed after one or more prior systemic treatments for stage IIIB/IV nonsquamous NSCLC. Efficacy and safety were evaluated in patients who received at least one dose of nivolumab. Results Of 1588 patients with nonsquamous NSCLC, 305 (19.2%) were never-smokers. EGFR status was available for 1395 patients. Of the 102 patients (6.4%) with EGFR mutation–positive tumors, 51 (50%) were never-smokers. The objective response rate was significantly higher in patients with wild-type EGFR than patients with EGFR-mutant tumors (19.6% versus 8.8% [p = 0.007]), in former and current smokers than in never-smokers (21.5% versus 9.2% [p = 0.0001]), and in never-smokers with wild-type EGFR than in never-smokers with mutant EGFR (11.0% versus 1.9% [p = 0.04]). There was no significant difference in objective response rate between smokers with wild-type EGFR and smokers with mutant EGFR (22.0% versus 20.6%). There was no statistically significant difference in median progression-free survival or in median overall survival. The median overall survival times were 11 months in patients with EGFR wild-type tumors versus 8.3 months in patients with EGFR-mutant tumors, 11.6 months in smokers versus 10.0 months in never-smokers, 11.0 months in never-smokers with EGFR wild-type tumors versus 5.6 months in never-smokers with EGFR-mutant tumors, and 14.1 months in smokers with EGFR-mutant tumors versus 11.3 months in smokers with EGFR wild-type tumors. Conclusions The data on the Italian expanded access program in populations with nonsquamous NSCLC suggest that subgroups of patients could benefit differently from nivolumab according to their EGFR mutational status and smoking habits. These results warrant further investigation.

Background In the late 1990s, the use of high-dose chemotherapy (HDCT) and stem-cell rescue held promise for patients with advanced and poor prognosis germ-cell tumors (GCT). We started a randomized phase II trial to assess the efficacy of sequential HDCT compared with cisplatin, etoposide, and bleomycin (PEB). Patients and methods Patients were randomly assigned to receive four cycles of PEB every 3 weeks or two cycles of PEB followed by a high-dose sequence (HDS) comprising HD-cyclophosphamide (7.0 g/m2), 2 courses of cisplatin and HD-etoposide (2.4 g/m2) with stem-cell support, and a single course of HD-carboplatin [area under the curve (AUC) 27 mg/ml × min] with autologous stem-cell transplant. Postchemotherapy surgery was planned on responding residual disease in both arms. The primary end point was progression-free survival (PFS). The study was designed to detect a 30% improvement of 5-year PFS (from 40% to 70%), with 80% power and two-sided α at 5%. Results From December 1996 to March 2007, 85 patients were randomized: 43 in PEB and 42 in HDS arm. Median follow-up was 114.2 months [interquartile range (IQR): 87.7–165.8]. Complete or partial response with normal markers (PRm-) were obtained in 28 (65.1%) and 29 (69.1%) patients, respectively. Five-year PFS was 55.8% [95% confidence interval (CI) 42.8–72.8] and 54.8% (95% CI 41.6%–72.1%) in PEB and HDS arm, respectively (log-rank test P = 0.726). Five-year overall survival was 62.8% (95% CI 49.9–79.0) and 59.3% (95% CI 46.1–76.3). One toxic death (PEB arm) was recorded. Conclusions The study failed to meet the primary end point. Furthermore, survival estimates of conventional-dose chemotherapy higher than expected should be accounted for and will likely limit further improvements in the first-line setting.

PURPOSE A single-center, prospective, nonrandomized trial was conducted to evaluate therapeutic results of a short-term program of chemotherapy followed by locoregional radiotherapy in stage I or II intermediate/aggressive non-Hodgkin's lymphoma (NHL). PATIENTS AND METHODS From 1985 to 1990, 183 consecutive patients with a diagnosis of NHL (Working Formulation [WF] E through J excluding Burkitt's type), Ann Arbor stage I or II, and no more than three sites of disease involvement were treated with four cycles of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) chemotherapy (six cycles in partial responders). Radiation therapy to initial sites of disease involvement (40 to 44 Gy) and to proximal uninvolved nodal region (36 Gy) was delivered shortly after completion of the chemotherapy program. RESULTS The complete remission (CR) rate was 98% at the end of combined therapy. Diagnostic excision of all measurable disease was performed in 33% of patients. In the remaining patients, 87% achieved CR with chemotherapy and 11% with radiation therapy, while three patients failed to achieve CR. After a median follow-up of 51 months, 26 patients have relapsed and 25 have died. The 5-year relapse-free and total survival rates were 83%. Aside from age older than 60 years, no other factor such as histology, stage, extranodal disease, bulky lymphoma, or abnormal lactic dehydrogenase (LDH) could predict for treatment outcome. There was a trend toward higher relapse rate for patients achieving CR at the time of radiation therapy (31%) as opposed to patients achieving CR with chemotherapy (15%) or with initial surgery (10%). Treatment was well tolerated and no deaths due to acute toxicity were observed. CONCLUSION For patients who present with limited-stage, aggressive NHL, a short course of CHOP chemotherapy followed by locoregional irradiation is safe, highly effective, and curative for most. Therefore, at the present time this approach can be regarded as standard therapy for these patients.
