Abstract

Hydrazine sulfate is an anticachexia agent which interrupts host energy wasting as a result of the malignant process. An inhibitor of gluconeogenesis at the phosphoenolpyruvate carboxykinase (PEP CK) reaction, this agent has been shown in randomized, placebo‐controlled, double‐blind trials to improve glucose tolerance, reduce glucose turnover, increase caloric intake, and increase or stabilize weight; in single‐arm controlled trials, this agent has been shown to increase appetite, improve performance status, decrease pain, diminish anorexia, normalize laboratory indices, stabilize tumor growth, induce tumor regression, and promote survival, while inducing little to no important clinical side effects. In view of its demonstrated capacity to effect anticancer response, this drug is suggested for trial as a sole agent in early drug‐resistant cancer, in combination with cytotoxic and related therapies, and in conjunction with total parenteral nutrition. It is postulated that effective control of the mechanisms associated with cancer cachexia may contribute to control of malignant disease.
