Abstract
One hundred and sixteen patients with advanced and metastatic adenocarcinoma of the pancreas were randomized to treatment with combined streptozotocin and 5-fluorouracil or combined streptozotocin and cyclophosphamide. Toxic reactions to each regimen were qualitatively similar and consisted of nausea and vomiting during the time of treatment and subsequent leukopenia and thrombocytopenia. Renal toxicity was less frequent and only rarely severe. Among 51 eligible and evaluable patients treated with the streptozotocin-cyclophosphamide combination, 12% showed objective response and among 42 patients treated with streptozotocin + 5-fluorouracil, 12% showed objective response. The streptozotocin + 5-fluorouracil treated patients showed a slight advantage in survival. Neither regimen can be considered of substantive value to the patient with advanced pancreatic carcinoma.
