Adenocarcinoma of the duodenum: factors influencing survival. French Association for Surgical Research.

The records of 66 patients with histologically proven adenocarcinoma of the duodenum were reviewed retrospectively to determine factors influencing survival. The parameters studied were age, sex, weight loss, jaundice, anaemia, duodenal stenosis, type of surgical procedure, tumour size and location, depth of parietal invasion, presence and location of lymph node metastases, and pancreatic invasion. These factors were assessed in a group of 46 patients who underwent curative resection of the tumour; 20 patients who received palliative procedures were excluded from statistical analysis. Survival curves were established by the Kaplan-Meier method and compared by the Mantel-Haentszel test. The actuarial 3- and 5-year survival rates of patients undergoing curative resection were 59 and 45 per cent respectively. None of the prognostic factors studied influenced survival. These results indicate that resection of adenocarcinoma of the duodenum should be performed whenever possible, even in the presence of lymph node metastasis and pancreatic spread.
