Carcinoma following gastric surgery: a national survey.

Definitive results of a national survey on the incidence of carcinoma following gastric surgery are reported. Data concern 8427 cases of surgically treated gastric cancer. 558 were affected by carcinoma following gastric surgery and 471 of them were operated on, representing 5.59% of all gastric cancers (8427) submitted to surgery. The statistical analysis of results has pointed out the need for a close follow-up program in patients over 50 years, operated on for benign gastroduodenal disease, especially 10 years postoperatively and in case of pre-cancerous lesions.
