Objective: To assess the efficacy of 5-fluorouracil (5-FU) and either platinum compounds or irinotecan in patients with advanced small bowel adenocarcinoma (SBA), for whom data on the efficacy of chemotherapy are scarce.
Methods: We reviewed data on all patients with advanced SBA who received chemotherapy over a 9-year period at our institution.
Results: Twenty patients with advanced SBA received a median of 6 cycles (range 2-15) of chemotherapy with 5-FU and either cisplatin (n=15), carboplatin (n=2), or oxaliplatin (n=3). The overall response rate was 21%, and median progression-free and overall survival 8 and 14 months, respectively. Toxicity was moderate. Second-line chemotherapy with 5-FU and irinotecan resulted in disease stabilization in 4 (50%) of 8 patients (median progression-free survival: 5 months), and in a biological complete response in another patient with non-measurable peritoneal carcinomatosis, allowing surgical cytoreduction surgery and hyperthermic intraperitoneal chemotherapy. No tumor response or disease stabilization was seen among the patients who received protracted venous infusion of 5-FU (n=4) or infusional 5-FU and cisplatin (n=1) as second-line chemotherapy.
Conclusion: Chemotherapy with 5-FU and platinum compounds seems effective and well-tolerated in patients with advanced SBA. 5-FU-irinotecan combination chemotherapy deserves further investigation in the first-line setting.
