title: Streptozotocin therapy in 22 cancer patients.
abstract: Twenty-two cancer patients were treated with streptozotocin (SZN) in six weekly intravenous doses of 1.0-1.5 g/m2. The results of the initial courses of therapy include 3 complete and 2 partial responses, 11 patients with no change, 4 with progression, and 2 deaths due to tumor progression. Three additional deaths also due to tumor progression occurred in previously responding patients. All responses were in patients with pancreatic tumor. Toxicity consisted of transient proteinuria in 11/15 patients, transient azotemia in 11/18 patients, marked reduction of creatinine clearance in 1 patient, burning pain at site of injection, nausea, and vomiting in 20/22 patients, change of FBS from pretherapy to post-therapy of at least 10 mg/100 ml in 11/17 patients, significantly decreased platelet count in 1/22 patients, decreased Hgb in 2/22 patients, and duodenal ulcer in 2/22 patients. A reduced dosage schedule and combination with other drugs known to be effective in pancreatic tumors deserves further investigations.
