Effects of streptozotocin in the WDHA syndrome not amenable to radical surgery.

Two cases of Verner-Morrison syndrome due to pancreatic carcinoma were treated H. h streptozotocin (STZ) according to the schedule suggested by the Division of Cancer Treatment of the National Cancer Institute. In both patients the drug caused a remission of the WDHA syndrome: therefore, this finding seems to recommend such treatment when the syndrome is not amenable to radical surgery. Renal toxicity is, however, an important limitation. It occurs mostly when STZ is administered by iv infusion. In one of the patients, after a serious impairment of renal function caused by STZ, prednisone controlled the syndrome for a long period of time.
