Survival after palliative surgery for advanced intraabdominal cancer

Abstract

The clinical course of 300 patients with known intraabdominal neoplasm requiring surgical exploration was analyzed. The most common primary tumor sites were the gastrointestinal tract (60 per cent), female reproductive organs (17 per cent), and urinary tract (6 per cent). Gastrointestinal and extrahepatic biliary obstruction, gastrointestinal bleeding, and peritonitis were the most common indications for surgery. The overall operative mortality was 26 per cent, and the mean survival time was 6.6 months. Small bowel fistulas, intraabdominal abscesses, and cardiopulmonary and renal failure were the leading causes of death. Palliative procedures in patients less than sixty years old with single site of obstruction or with tumor of gastrointestinal origin were associated with a low operative mortality and prolonged survival. On the other hand, surgical intervention in patients more than seventy years old undergoing chemotherapy, with multiple sites of obstruction, peritonitis, or primary tumor originating outside the gastrointestinal tract, was associated with high operative mortality and seldom benefited from palliative intervention. Surgical intervention to relieve a distressing symptom in a patient with advanced neoplasm is a well established procedure, but the risks and benefits of such intervention should be carefully weighed against the expected mortality and the quality of survival.
