Folfirinox in elderly patients with pancreatic or colorectal cancer-tolerance and efficacy.

ABSTRACT: To study the tolerance and the efficiency of FOLFIRINOX in elderly patients diagnosed with colorectal or pancreatic cancer.This retrospective study included elderly patients aged over 70 years of age treated at Georges-Francois Leclerc Center by FOLFIRINOX for histological proved colorectal or pancreatic cancer between January 2009 and January 2015. Chemotheapy regimen consisted of oxaliplatin (85 mg/m2 in over 120 min) followed by leucovorin (400 mg/m2 in over 120 min), with the addition, after 30 min of irinotecan (180 mg/m2 in over 90 min) then 5 fluorouracil (5FU) (400 mg/m2 administred intravenous bolus), followed by 5FU (2400 mg/m2 intraveinous infusion over 46 h) repeated every 2 wk. Geriatric parameters were recorded at the beginning. Toxicities were evaluated with the Common Terminology Criteria for Adverse Events 4.03. Tumor response was evaluated by CT scan. Treatment continued until disease progression, unacceptable toxicities or patient refusal.Fifty-two patients aged from 70 to 87 years were treated by FOLFIRINOX, 34 had colorectal cancer and 18 had pancreatic cancer. Most of them were in good general condition, 82.7% had a 0-1 performance status and 61.5% had a Charlson Comorbidity Index < 10. The most frequent severe toxicities were neutropenia (17 patients, n = 32.7%) and diarrhea (35 patients n = 67.3%); 10 of the case of neutropenia and 5 of diarrhea registered a grade 4 toxicity. Thirty-nine patients (75%) initially received an adapted dose of chemotherapy. The dosage was adjusted for 26% of patients during the course of treatment. Tumor response evaluated by RECIST criteria showed a controlled disease for 25 patients (48.1%), a stable disease for 13 and a partial response for 12 patients. Time under treatment was higher for colorectal cancer with a median time of 2.44 mo (95%CI: 1.61-3.25). Overall survival was 43.88 mo for colorectal cancer and 12.51 mo for pancreatic cancer. In univariate or multivariate analysis, none of geriatric parameters were linked to overall survival. Only the type of tumor (pancreatic/colorectal) was linked in both analysis.For people over 70 years old, FOLFIRINOX regimen seems to induce manageable toxicities but similar, even higher, median survival rates compared to younger people.

Project description:BackgroundIrinotecan-based chemotherapy is a standard backbone of therapy in patients with metastatic colorectal cancer (CRC) or gastric cancer (GC). However, there is still a paucity of information concerning the efficacy and safety of irinotecan-based regimens in elderly patients.Patients and methodsUsing the patient cohort (n = 1,545) from the UGT1A1 genotype study, we compared the efficacy and safety between elderly and nonelderly patients with metastatic CRC (n = 934) or GC (n = 611) who received first- or second-line FOLFIRI (irinotecan, leucovorin, and 5-fluorouracil) chemotherapy.ResultsDespite lower relative dose intensity in elderly patients, progression-free survival and overall survival were similar between elderly (age ≥70 years) and nonelderly (<70 years) patients in the CRC cohort (hazard ratio [HR], 1.117; 95% confidence interval [CI], 0.927-1.345; p = .244, and HR, 0.989; 95% CI, 0.774-1.264; p = .931, respectively) and the GC cohort (HR, 1.093; 95% CI, 0.854-1.400; p = .479, and HR, 1.188; 95% CI, 0.891-1.585; p = .241, respectively). In both cohorts, febrile neutropenia (22.1% vs. 14.6% in CRC cohort and 35.2% vs. 22.5% in GC cohort) and asthenia (grade 3: 8.4% vs. 1.7% in CRC cohort and 5.5% vs. 2.9% in GC cohort) were more frequent in elderly patients. In the CRC cohort, mucositis and anorexia were more frequent in elderly patients. In the GC cohort, nausea and vomiting were less frequent in elderly patients.ConclusionThe efficacy of the FOLFIRI regimen was similar between elderly and nonelderly patients in both the CRC and the GC cohorts. However, special attention should be paid to elderly patients because of increased risk for febrile neutropenia and asthenia. The Oncologist 2017;22:293-303 IMPLICATIONS FOR PRACTICE: The efficacy of FOLFIRI (irinotecan, leucovorin, and 5-fluorouracil) chemotherapy in elderly patients with metastatic colorectal cancer or gastric cancer was similar to that in nonelderly patients. However, special attention should be paid to elderly patients because of the increased risk for febrile neutropenia and asthenia. These data suggest that the FOLFIRI regimen could be considered as a standard backbone of therapy in elderly patients with metastatic colorectal cancer or gastric cancer and that the clinical decision between doublet and singlet chemotherapy may not be based solely on age. However, the data require further assessment of frailty and performance status.
