Haemorrhage and perforation of gastrointestinal neoplasms during chemotherapy.

Gastrointestinal haemorrhage and perforation are known complications of cytotoxic therapy for chemosensitive tumours involving the wall of the gut, in particular non-Hodgkin's lymphoma. These complications can be avoided by aggressive surgery before chemotherapy is started. When they do occur, early operative intervention is essential to reduce morbidity and mortality. We report 4 cases in whom delay in diagnosis and surgery led to 3 deaths and suggest a policy for the management of such cases in the future.
