Spontaneous gastroduodenal perforation in cancer patients receiving cytotoxic therapy.
Spontaneous gastroduodenal perforation (SGDP) occurs in cancer patients receiving cytotoxic drugs, corticosteroids, or radiation therapy as primary or adjuvant treatment for their tumors. A retrospective review identified 12 patients from 1974 to 1987 at the Memorial Sloan-Kettering Cancer Center who underwent surgery for SGDP while receiving anticancer therapy. There were five gastric and seven duodenal perforations. Vague abdominal pain was the most common symptom. Exploration was delayed in six patients because of an absence of physical findings. All patients received a Graham omental patch. The in-hospital operative mortality was 33%, with all major complications occurring in those that died. There were no prognostic indicators identified that would preoperatively predict outcome. Aggressive surgical intervention is advised in all patients who have a reasonable chance of worthwhile palliation if not cure.
