Response to FOLFIRINOX by gender in patients with metastatic pancreatic cancer: Results from the PRODIGE 4/ ACCORD 11 randomized trial.

ABSTRACT: Hohla et al. suggested that female gender could positively predict response to FOLFIRINOX in patients with advanced pancreatic cancer. In this study, we explored the response to the FOLFIRINOX regimen by gender within the trial PRODIGE4/ACCORD 11.Data were described by gender, both in FOLFIRINOX group and in the intention-to-treat population of the trial. The relative effect of gender (females in comparison to males) on overall survival (OS) and progression-free survival was estimated by using a Cox proportional hazard model and was presented with the Hazard Ratio and their 95% confidence interval. The analysis of prognostic factors of OS included also: age (older than 65 years), ECOG performance status, primary tumor location, synchronous metastases, number of metastatic sites, hepatic metastasis, pulmonary metastases, lymph node metastases, level of Albumin and level of serum carbohydrate antigen 19-9 and three domains from the EORTC Quality of Life QLQC-30 questionnaire.The FOLFIRINOX group (N = 171 patients) included 106 women (62%) and 65 men. No significant differences were observed between genders regarding demographic and clinical parameters, excepted for lymph nodes metastasis (17% and 35% in women and men respectively; p = 0.012). Median OS was longer for females as compared to males in FOLFIRINOX group (13.1 versus 10.3 months respectively; HR = 0.73; 95% CI, 0.51-1.06). Similarly, median PFS was superior (7.2 versus 5.9 months; HR = 0.79; 95% CI, 0.57-1.10). Nevertheless, in both cases, the differences were not statistically significant (p = 0.10 et p = 0.169, respectively).In this study, the overall survival and progression-free survival rates were not significantly higher for females than for males in FOLFIRINOX group (HR = 0.73; 95% CI, 0.51-1.06 and HR = 0.79; 95% CI, 0.57-1.10 respectively). Even if the percentage of patients with lymph node metastasis is higher for males than for females, the interaction between gender and lymph node metastasis was non-significant. Our exploratory analysis did not permit to definitively conclude about a possible effect of gender on the prognosis of patients under FOLFIRINOX. This subject deserves further evaluation.ClinicalTrials.gov number: NCT00112658.Our analysis suggests that FOLFIRINOX, as first-line option for patients with metastatic pancreatic cancer who are younger than 76 years and who have a good performance status (ECOG 0 or 1), no cardiac ischemia and normal or nearly normal bilirubin levels, is beneficial, but not particularly in female patients.

Project description:PURPOSE:Pegylated recombinant human hyaluronidase (PEGPH20) degrades hyaluronan (HA) and, in combination with chemotherapy, prolongs survival in preclinical models. The activity of PEGPH20 with modified fluorouracil, leucovorin, irinotecan, and oxaliplatin (mFOLFIRINOX) was evaluated in patients with metastatic pancreatic cancer (mPC). MATERIALS AND METHODS:Patients had untreated mPC, a performance status of 0 to 1, and adequate organ function. Tumor HA status was not required for eligibility. After a phase Ib dose-finding study of mFOLFIRINOX plus PEGPH20, the phase II open-label study randomly assigned patients (1:1) to the combination arm or to mFOLFIRINOX alone (n = 138). The primary end point was overall survival (OS). RESULTS:PEGPH20 dosages of 3 µg/kg every 2 weeks were more tolerable than twice-weekly dosages used in the phase I study, so 3 µg/kg every 2 weeks was the phase II dosage. An amendment instituted enoxaparin prophylaxis in the PEGPH20 combination arm as a result of increased thromboembolic (TE) events. The planned interim futility analysis when 35 deaths (of 103 analyzable patients) occurred resulted in an OS hazard ratio (HR) of 2.07 that favored the control arm, and the study was closed to accrual. The treatment-related grade 3 to 4 toxicity was significantly increased in the PEGPH20 combination arm relative to control (odds ratio, 2.7; 95% CI, 1.1 to 7.1). The median OS in the mFOLFIRINOX arm was 14.4 months (95% CI, 10.1 to 15.7 months) versus 7.7 months (95% CI, 4.6 to 9.3 months) in the PEGPH20 combination arm. CONCLUSION:Addition of PEGPH20 to mFOLFIRINOX seems to be detrimental in patients unselected for tumor HA status. This combination caused increased toxicity (mostly GI and TE events) and resulted in decreased treatment duration compared with mFOLFIRINOX alone. The median OS in the mFOLFIRINOX control arm (14.4 months) is, to our knowledge, the longest yet reported and can be considered for patients with good PS.

Project description:BACKGROUND:Preoperative radiochemotherapy (RCT) is recommended in France prior to total mesorectal excision in patients with mid or low locally advanced rectal cancer (LARC) (cT3/T4 and/or N+) because it has been shown to improve local control. Preoperative RCT has also disadvantages including the absence of proven impact on metastatic recurrence and the risk of late side effects on bowel and genitourinary function. In patients with primarily resectable LARC, preoperative systemic chemotherapy without pelvic irradiation could be used as an alternative to RCT. METHODS:This study is a multicenter, open-label randomized, 2-arm phase III non-inferiority trial. Patients with mid or low resectable LARC (cT3N0 or cT1-T3N+ with circumferential resection margin [CRM]?>?2?mm on pretreatment MRI) will be randomized to either modified FOLFIRINOX for 3?months or RCT (Cap50 intensified-modulated radiotherapy). All patients have restaging MRI after preoperative treatment. The primary endpoint is 3-year progression-free survival (PFS) from the time to randomization including progression during preoperative treatment. Secondary endpoints are treatment related toxicity, treatment compliance, R0 resection rate, sphincter saving surgery rate, postoperative morbidity and mortality rates, loco-regional recurrence free survival, overall survival, bowel and sexual functions at diagnosis, quality of life, radiologic and pathologic response after preoperative treatment. The number of patients required is 574. DISCUSSION:The choice of modified FOLFIRINOX for preoperative chemotherapy is supported by recent and consistent data on safety and efficacy of this regimen on rectal cancer. The use of preoperative chemotherapy instead of RCT could be associated with pronounced advantages in terms of functional results and quality of life in cancer survivors. However and first of all, the non-inferiority of preoperative chemotherapy compared to RCT on oncologic outcome has to be validated. If this study demonstrates the non-inferiority of chemotherapy compared to RCT, this can lead to a crucial change in clinical practice in a large subset of rectal cancer patients.
