[Causes of nonradical surgical operations for cancer of the proximal part of the stomach].
An analysis of results of treatment of 454 patients operated for cancer of the proximal part of the stomach included the main parameters of the tumor process and radical operations studied on the basis of morphological investigations of the ablated preparations. The vertical and horizontal lines of the gastric resection were thoroughly investigated, the results being introduced in the protocol of the investigation. In 49 of 454 radically operated patients (10.7%) the line of resection passed through the zone of tumor infiltration. It was shown that the frequency of the tumor cells left along the resection line was substantially influenced not only by the growth character, the histological structure of the tumor and involvement of the esophagus, but also by the kind of operative access and surgery. We believe that in patients with poorly differentiated carcinomas (G3-G4) and endophylic-infiltrative forms of tumor growth it is necessary to principally widen the resection zones both in the vertical and lateral directions. It will allow avoidance of making the line of resection in the tumor infiltration zone. Not only the gastric resection zones but also all anatomical structures adjacent to the tumor ablated during the combined surgical operations should be thoroughly morphologically examined. The intraoperative urgent histological investigation of the gastric resection line must be made in all radical operations for gastric cancer.
