Clinicopathologic features and prognostic significance of duodenal invasion in patients with distal gastric carcinoma

Abstract: Clinicopathologic features and prognostic significance of duodenal invasion were studied in a retrospective study on 593 patients who underwent gastrectomy for adenocarcinoma in the antrum. The patients were grouped into three, according to the histologic extent of duodenal invasion: Group A (80 patients), obvious invasion beyond the pyloric ring; Group B (61 patients), invasion up to the pyloric ring; and Group C (452 patients), no evidence of duodenal invasion. Five-year survival rates in Groups A, B, and C … Show more

“…Tumors in the middle-third of the stomach are more likely to be cured by surgical resection (resulting in longer survival time for the patient [33]) than tumors located in the upper-third and lower-third of the stomach. This phenomenon may be attributed to findings that tumors in the upper-third of the stomach invade the esophagus [34,35], while those in the lower-third invade the duodenum [36].…”

“…Relatam-se percentagens de invasão duodenal de 9,2% a 68,9% em material de necropsia e de 11% a 33,3% em peças cirúrgicas (1,2,3,4,5,6,7,8,10,12,13,14,15,16,17,18,19,21,22) . Todavia, esse fato é relatado raramente em livros de texto médico e nos mais antigos afirma-se que o carcinoma gástrico pára abruptamente na altura do piloro.…”

“…É provável que essa falsa impressão se deva ao fato de que, na maior parte das vezes, a invasão duodenal e até mesmo do piloro não seja percebida macroscopicamente, sendo diagnosticada apenas na superfície de corte ou no exame histológico. Na maioria dos casos ocorre infiltração da intimidade da parede duodenal abaixo das glândulas de Brünner, estando estas e a mucosa mais preservadas (3,6,7,17,22) . Na maioria das casuísticas estudadas, relata-se que a invasão ocorre preferencialmente em neoplasias em estádios III e IV, com padrão de crescimento infiltrativo e classificadas histologicamente como adenocarcinomas pouco diferenciados.…”
