The purpose of the present study was to evaluate the activity and the tolerability of the FOLFIRI regimen, administered as second-line chemotherapy in patients with locally advanced or metastatic pancreatic cancer after the failure of a gemcitabine-based regimen.
Patients with locally advanced/metastatic disease who received a first-line chemotherapy (one line only) with gemcitabine ± platinoid (cisplatin, oxaliplatin) and who had measurable disease conform with the RECIST criteria were eligible for the study.
FOLFIRI consists of irinotecan 180 mg/m2 iv on day 1, leucovorin (l-form) 200 mg/m2 iv on day 1 and 2, 5-FU 400 mg/m2 iv bolus on days 1 and 2, and 5-FU 600 mg/m2 iv by ci for 22 h on days 1 and 2, repeated every 2 weeks. The primary end point was the response rate.
Among the 50 enrolled patients, 4 partial responses (PR) (8 %) and 14 stable diseases were observed, for a disease control rate of 18/50 (36 %). Forty-one patients (82 %) have been pretreated with cisplatin/oxaliplatin+gemcitabine as first-line chemotherapy. The median progression-free and overall survivals were 3.2 and 5 months, respectively. The 6-month survival rate was 32 %. Grade 3–4 neutropenia and diarrhea occurred in 10 (20 %) and 6 (12 %) patients, respectively.
The FOLFIRI regimen showed a modest clinical activity in this quite heavily pretreated patients’ population with locally advanced or metastatic pancreatic cancer with a manageable toxicity profile.
