Hexamethylmelamine in adenocarcinoma of the pancreas and liver.

Ten patients with advanced adenocarcinoma of the pancreas were treated with hexamethylmelamine 8 mg/kg/day in oral, divided doses. One of the five patients with measurable disease had a partial response which lasted 5 months. One of the five patients with no measurable disease treated for 52 months with hexamethylmelamine survived a total of 59 months. This experience suggests that hexamethylmelamine may be an active drug in the treatment of pancreatic cancer.
