RESUMO
BACKGROUND: The chemotherapy triplet FOLFOXIRI combined to the anti-VEGF antibody bevacizumab is an option in selected patients with metastatic colorectal cancer. In this setting, RAS-mutated metastatic colorectal cancer do not benefit the same from treatment than RAS-wildtype metastatic colorectal cancer do. Together with its antiangiogenic properties, the tyrosine-kinase inhibitor regorafenib has also anti-proliferative activities whatever the RAS status is. The present trial aims at studying the safety and the efficacy of regorafenib in combination with FOLFIRINOX - a chemotherapy triplet using a different dosing schedule than FOLFOXIRI - in patients with RAS-mutated metastatic colorectal cancer. METHODS: FOLFIRINOX-R is a prospective, multicentric, non-randomised, dose-finding phase 1-2 trial. The primary endpoints are the determination of the maximum tolerated dose, the recommended phase 2 dose, and the proportion of patients achieving disease control at 48-weeks. Phase 1 follows a 3 + 3 design (12 to 24 patients to be included). Sixty nine patients will be necessary in phase 2, including 5% non-evaluable ones, with the following assumptions, one-stage Fleming design, α = 5%, ß = 20%, p0 = 35% and p1 = 50%. Key eligibility criteria include Eastern Cooperative Oncology Group Performance Status of ≤1 and RAS-mutated metastatic colorectal cancer not amenable to surgery with curative intent and not previously treated for metastatic disease. FOLFIRINOX (oxaliplatin 85 mg/m2, folinic acid 400 mg/m2, irinotecan 150-180 mg/m2, 5-fluorouracil: 400 mg/m2 then 2400 mg/m2 over 46 h) is administered every 14 days. Regorafenib (80 to 160 mg, as per dose-level) is administered orally, once daily on days 4 to 10 of each cycle. DISCUSSION: FOLFIRINOX-R is the first phase I/II study to evaluate the safety and efficacy of regorafenib in combination with FOLFIRINOX as frontline therapy for patients with RAS-mutated metastatic colorectal cancer.

PURPOSE: Sexual quality of life (QoL) is affected during and after breast cancer (BC) treatment and is not specifically evaluated with the general health-related quality-of-life questionnaires EORTC QLQ-C30 or QLQ-BR23. A specific questionnaire, the EORTC SHQ-C22, including physical, psychological, and social aspects of sexuality, was recently developed to address this issue in cancer patients. METHODS: A prospective bicentric study was conducted to evaluate the sexual QoL of women with BC during the first year of adjuvant hormonal treatment. RESULTS: A total of 106 women completed the 3 questionnaires at baseline and 92 of them, at 12 months. At baseline, we showed low sexual satisfaction and importance given to sexual activity and a very low communication with healthcare professionals about this issue. Twelve months later, the importance given to sexuality had increased. While the communication with professionals had improved, it remained at a very low level. We were unable to identify specific clinical factors (chemotherapy, menopausal status, type of surgery or radiotherapy) that would negatively affect the global sexual well-being in BC patients. CONCLUSION: The analysis of sexual QoL of BC patients during the first year of hormonal treatment with a recently developed, cancer-dedicated, standardized tool pointed out the need for deeper communication between professionals and patients regarding sexual issues to fill the current gap in care of cancer patients and help patients with adequate intervention and support.

BACKGROUND: Malignant peritoneal mesothelioma (MPM) is a rare tumoral disease characterized by the diffuse involvement of the peritoneal serosa. The standard frontline treatment of MPM is cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (HIPEC) unless the peritoneal disease is considered unresectable. For unresectable patients the standard frontline treatment is a combination of cisplatin and pemetrexed but the prognosis remains ominous with only 13 months of overall survival (OS). METHODS: The proposed study is a multicenter randomized non-comparative study evaluating the association of Pressurized Intra-Peritoneal Aerosol Chemotherapy (PIPAC) and systemic chemotherapy vs. systemic chemotherapy alone as first-line treatment of MPM. Patients will be randomized with a 2:1 ratio using a minimization technique. Sixty-six patients have to be enrolled. Stratification will be performed according to histology (epithelioid vs. sarcomatoid and biphasic), presence of extraperitoneal disease and center. Primary objective is OS and secondary objectives include progression-free survival (PFS), safety, compliance, feasibility, conversion to resectability, histological response to treatment and quality of life. CONCLUSIONS: We expect to show that intensification of the first line treatment with PIPAC for initially unresectable MPM patients increases OS. TRIAL REGISTRATION: Prospective study.

RESUMO
BACKGROUND: The primary aim of this trial was to determine the recommended phase II dose (RP2D) of weekly paclitaxel (wP) administered in combination with oral metronomic cyclophosphamide (OMC). METHODS: Patients ≥ 18 years of age with refractory metastatic cancers were eligible if no standard curative measures existed. Paclitaxel was administered IV weekly (D1, D8, D15; D1 = D28) in combination with a fixed dose of OMC (50 mg twice a day). A 3 + 3 design was used for dose escalation of wP (40 to 75 mg/m2) followed by an expansion cohort at RP2D. Dose-limiting toxicity (DLT) was defined over the first 28-day cycle as grade ≥ 3 non-hematological or grade 4 hematological toxicity (NCI-CTCAE v4.0) or any toxicity leading to a dose reduction. RESULTS: In total, 28 pts. (18 in dose-escalation phase and 10 in expansion cohort) were included, and 16/18 pts. enrolled in the dose-escalation phase were evaluable for DLT. DLT occurred in 0/3, 1/6 (neuropathy), 0/3 and 2/4 pts. (hematological toxicity) at doses of 40, 60, 70 and 75 mg/m2 of wP, respectively. The RP2D of wP was 70 mg/m2; 1/10 patients in the expansion phase had a hematological DLT. At RP2D (n = 14), the maximal grade of drug-related adverse event was Gr1 in three patients, Gr2 in six patients, Gr3 in one patient and Gr4 in one patient (no AE in three patients). At RP2D, a partial response was observed in one patient with lung adenocarcinoma. CONCLUSION: The combination of OMC and wP resulted in an acceptable safety profile, warranting further clinical evaluation. TRIAL REGISTRATION: TRN: NCT01374620 ; date of registration: 16 June 2011.

BACKGROUND: In a placebo-controlled, randomized phase 2 trial (ClinicalTrials.gov identifier NCT01900743), regorafenib improved progression-free survival (PFS) for patients with doxorubicin-pretreated advanced nonadipocytic sarcoma. A quality-adjusted time without symptoms of progression or toxicity (Q-TWiST) post hoc exploratory analysis was applied to provide an integrated measure of its clinical benefit. METHODS: In the base-case analysis, each patient's overall survival (OS) was partitioned into 3 mutually exclusive health states: the time with a grade 3 or 4 adverse event (TOX), the time without symptoms of disease or grade 3 or 4 toxicity from treatment, and the time after tumor progression or relapse. The time spent in each state was weighted with a health-state utility associated with that state and was summed to calculate the Q-TWiST. The stability of the base-case analysis was explored with several sensitivity analyses. RESULTS: In nonadipocytic sarcoma, the PFS was (4.0 months [2.6-5.5 months] with regorafenib vs 1.0 month [0.9-1.8 months] with a placebo; hazard ratio, 0.36 [0.25-0.53]; P < .0001); the OS was 13.4 months (8.6-17.3 months) with regorafenib and 9.0 months (6.8-12.5 months) with a placebo (hazard ratio, 0.67 [0.44-1.02]). With the classic definition of TOX (including all grade 3 and 4 clinical adverse events), the Q-TWiSTs were 8.0 months (7.0-9.0 months) with regorafenib and 5.7 months (4.9-6.4 months) with a placebo (P < .001). CONCLUSIONS: For patients with doxorubicin-pretreated soft-tissue sarcoma, regorafenib significantly improved quality-adjusted survival in comparison with a placebo.
