| Popis: | e15747 Background: FOLFIRINOX is a highly effective combination chemotherapy regimen with the reputation of only being tolerable to young patients with good performance status. As the original ACCORD study was carried out at specific French university hospitals with patients performance status 0 or 1 many oncologists feel uncomfortable administering mFOLFIRINOX as a second-line therapy. We have previously reported our experience in 24 patients ages 27 - 84 where we concluded that dose modified FOLFIRINOX can be safely administered to elderly patients with appropriate initial dose reductions and subsequent escalation. There is a lack of consensus on a standard second-line regimen for metastatic pancreatic cancer. We conducted a review of dose intensity and outcome for all patients treated with 2nd or 3rd-line mFOLFIRINOX for pancreatic adenocarcinoma at St John of God Hospital, Subiaco, Western Australia in order to assess efficacy and tolerability Methods: Electronic records were used to identify 35 patients who had received 1st-line gemcitabine-based chemotherapy who then went on to receive 2nd or 3rd line mFOLFIRINOX. Case files, laboratory and radiology records were then examined to determine outcomes and toxicities. Results: 35 patients were identified with an age range of 27- 85, both locally advanced and metastatic disease, with 12 over the age of 70. All patients except 2 had gemcitabine plus abraxane in the first line setting. Dose intensity was 65% for oxaliplatin, 68% for irinotecan, 18% for bolus 5-FU and 68% fir infusional 5FU. Toxicity was acceptable with a grade 3 toxicity rate of 10%. Overall survival in this group ranged from 5-67 months (median 23 months for locally advanced / 15 months for metastatic). Notably, 20 patients received greater than 6 cycles of treatment and 8 patients received more than 12 cycles. One patient has received 70 cycles. Conclusions: Our experience demonstrates the safety, tolerability and efficacy of mFolfirinox as a second-line therapy after gemcitabine failure. The disease control rate, even with the reduction in dose intensity, suggests that modified Folfirinox should be formally tested in the 2nd line setting in a clinical trial. |
