Palliative surgery for far-advanced gastric cancer: a retrospective study on 305 consecutive patients.

Few reports of the Western countries have investigated the value of palliative surgery for stomach cancer. The aim of this study was to evaluate the results of palliative surgery in a large series of patients affected by gastric carcinoma, consecutively treated by the same surgical team. The hospital records of 305 patients affected by gastric cancer who did not undergo surgical treatment or who underwent a palliative surgical procedure at our unit between 1981 and 1995 were reviewed. Univariate and multivariate analyses were used to calculate the 5-year survival probabilities with respect to the following variables: demographic data, tumor location and gross appearance, spread of the disease, histological type according to P. Lauren, and type of treatment. Multivariate logistic regression analysis showed that resectional surgery and tumor spread limited to local sites were independently associated with better survival. The study indicates that even though there are host-related factors that govern survival in far-advanced stomach cancer, the type of surgery can have a significant effect on prognosis; resectional surgery should be undertaken whenever possible in such patients.
