Abstract
BACKGROUND:
Small bowel adenocarcinoma (SBA) is a rare tumor with poor prognosis. First‐line platinum‐based chemotherapy is active in patients with advanced SBA, but data regarding second‐line chemotherapy are lacking. The aim of this study was to evaluate the efficacy and tolerability of fluorouracil, leucovorin, and irinotecan (FOLFIRI regimen) as second‐line chemotherapy in patients with advanced SBA.
METHODS:
We analyzed all consecutive patients who received second‐line chemotherapy with FOLFIRI among 93 patients with advanced SBA included from 1996 to 2008 in a previous retrospective multicenter study. Progression‐free survival (PFS) and overall survival (OS) were estimated from the start of second‐line chemotherapy using the Kaplan‐Meier method. Cox models were applied for multivariate analyses.
RESULTS:
Among 51 patients who received second‐line chemotherapy, 28 patients (male, 57%; median age, 54 years; metastatic disease, 96%) were treated with FOLFIRI after progression (n = 24) or limiting toxicity (n = 4) to first‐line FOLFOX (n = 19) or LV5FU2‐cisplatin (n = 9). Grade 3‐4 toxicity was observed in 48% of patients (grade 3‐4 neutropenia, 37%). After a median follow‐up of 21.5 months, all patients had tumor progression, and 22 patients died. Objective response rate was 20%, and disease control rate was 52%. Median PFS and OS were 3.2 and 10.5 months, respectively. No clinical, biological, or tumor characteristics were associated with PFS or OS by multivariate analysis.
CONCLUSIONS:
Second‐line chemotherapy with FOLFIRI produced disease control in half of patients with advanced SBA after failure with first‐line platinum‐based chemotherapy. Nevertheless, the short median PFS warrants the evaluation of other treatments including targeted therapies. Cancer 2011. © 2010 American Cancer Society.
