通常将局部手术野以及残胃上的复发癌称为局部复发性胃癌。因多数局部复发性胃癌来源于局部手术野,难以获得组织学诊断。胃癌根治术对原发灶及其邻近的组织进行了广泛的切除后,就形成了以手术野为中心的、包含诸多重要脏器、血管在内的广泛粘连。癌组织局部复发后就非常容易累及粘连于周围的重要脏器或血管,多无法切除。局部复发癌在累及邻近脏器的同时也侵入相应脏器的淋巴网络,使其淋巴结转移范围更广泛。手术切除仍是局部复发性胃癌的首选方法,但能够切除者不多。初次手术时准确的术前诊断是防止局部复发的第一环节,规范性手术、必要的术前化疗则是预防复发的重要步骤。
Local surgical field and recurrent cancer in the residual stomach are often referred to as locally recurrent gastric cancer. Because most of the local recurrence of gastric cancer from the local surgical field, difficult to obtain histological diagnosis. Radical gastric cancer radical resection of the primary tumor and its adjacent tissues, the formation of the surgical field as the center, contains many important organs, blood vessels, including a wide range of adhesions. Local recurrence of cancerous tissue is very easy to involve adhesions in the surrounding organs or blood vessels, and more can not be removed. Local recurrence cancer invades the adjacent organs, but also invades the lymph nodes of the corresponding organs, making the lymph node metastasis more extensive. Surgical resection is still the preferred method of local recurrent gastric cancer, but few resection. Accurate preoperative diagnosis of the first operation is to prevent the first part of the local recurrence, normative surgery, the necessary preoperative chemotherapy is an important step in the prevention of recurrence.
