COMPOSITE TUMORS OF THE STOMACH - REPORT ON 9 CASES

Nine gastric adenocarcinomas containing endocrine cells were retrospec tively studied to evaluate anatomo-clinical and immunohistochemical fe atures, and the out-come of the patients. These gastric tumors were bu lky with frequently lymph node metastasis. The immunohistochemical ana lysis had shown that all tumors contain EC cells, two tumors D cells, one tumor PP cells, but neither G cells nor A cells were detected. Fiv e-years survival rate of these gastric tumors was slightly but not sig nificantly increased as compared to usual adenocarcinomas (45.5 % vs 3 6.5 %). However, one can raise the question of possible control of loc al hormonal secretions on tumoral growth, particularly the antitrophic part of the somalostatin.
