Abstract

Evidence suggests that interferon-α (IFN-α) augments the antineoplastic activity of 5-fluorouracil (5-FU) in human adenocarcinoma cell lines in vitro and may enhance the efficacy of 5-FU in patients with advanced colorectal carcinoma. In addition, 5-FU may be more effective when given as a prolonged, continuous i.v. infusion (PCI). The Eastern Cooperative Oncology Group performed a Phase II trial of PCI 5-FU plus IFN-α in patients with advanced pancreatic carcinoma. Twenty-six patients with advanced, surgically incurable adenocarcinoma of the pancreas received PCI 5-FU (250 mg/m2 daily for 28 days) in combination with IFN-α (5 x 106 IU/m2 s.c. thrice weekly). Treatment cycles were repeated 14 days or longer after completion of the previous cycle. Treatment was interrupted prior to day 28 if intolerable toxicity developed, and the dose of 5-FU was reduced in subsequent cycles. Partial response occurred in two of 24 evaluable patients (8%; 95% confidence interval, 0-19%). The majority of the study group (88%) had liver metastases. Patients whose serum lactate dehydrogenase (LDH) was more than twofold elevated developed 5-FU-related toxicity significantly sooner than patients with smaller elevations in serum LDH (9 vs. 22 days; p = 0.003). A similar trend was observed for patients with a more than twofold elevation in serum glutamic-oxaloacetic transaminase (SGOT; 9 vs. 15 days; p = 0.07). In conclusion, PCI 5-FU plus IFN-α has minimal activity in patients with advanced pancreatic carcinoma, and elevated serum LDH and/or SGOT may be useful for predicting greater toxicity from 5-FU-based therapy in patients with liver metastases.
