为了判断早期胃癌手术时淋巴结应切除的范围,作者等对274例胃癌患者的原发病灶侵润范围与淋巴结受侵的发生率作了研究;同时还分析了淋巴结转移数目、受侵程度和原发癌肿组织学类型间的关系。位于远端1/3胃部的隆起型胃癌,凡已侵及粘膜下层而直径在3cm以上者,病灶虽尚属早期,其淋巴结转移的发生率却较高,但受侵的淋巴结多在原发灶的邻近部位(第一组淋巴结)。癌肿已侵及肌层者,可出现远隔淋巴结转移(第二组或第三组淋巴结)。转移淋巴结的数目及范围,与原发病灶侵润范围呈正相关。
To determine the extent of lymph node resection during early gastric cancer surgery, the authors studied the extent of primary lesion invasion and the incidence of lymph node invasion in 274 patients with gastric cancer; the number of lymph node metastases, the degree of invasion, and the original The relationship between the histological type of cancer. Uplifted gastric cancer located in the distal 1/3 of the stomach, which has invaded the submucosa and has a diameter of more than 3 cm, although the lesion is still early, the incidence of lymph node metastasis is higher, but the invaded lymph nodes are mostly in the original The proximal part of the focus (the first group of lymph nodes). Patients with cancer that have invaded the muscular layer may have distant lymph node metastases (second or third group lymph nodes). The number and extent of metastatic lymph nodes were positively correlated with the extent of primary lesion invasion.
