作者分析277例浆膜受侵的晚期胃癌,旨在研究浆膜侵袭长度(LSI)与预后之间的关系。肿瘤分为扩展型88例(32%)和浸润型189例(68%)。扩展型的LSI为0.1～10 cm,其中约半数为0.1～2 cm;浸润型的LSI为0.1～19 cm。扩展型的5年生存率在L-SI小于4 cm者为40%,LSI 4.1～6 cm者为33%,LSI大于6 cm者为13%。浸润型的5年生存率,在LSI小于2cm为53%,而大于2 cm者,生存时间很短(P<0.01)。淋巴结受侵者,计扩展型67例,浸润型147例,除了LSI O.1～2 cm的浸润型肿瘤外,任
The authors analyzed 277 cases of serosa invasive advanced gastric cancer in order to study the relationship between serosal invasion length (LSI) and prognosis. Tumors were divided into expanded (88%) and infiltrated (189%) cases (32%). The extended LSI is 0.1 to 10 cm, about half of which is 0.1 to 2 cm, and the infiltrated LSI is 0.1 to 19 cm. The extended 5-year survival rate was 40% for L-SI less than 4 cm, 33% for LSI 4.1 to 6 cm, and 13% for LSI greater than 6 cm. The 5-year survival rate of the infiltrating type was 53% in LSI less than 2 cm, but the survival time was very short (P<0.01). Lymph nodes were invaded, including 67 cases of extended type and 147 cases of infiltrative type. In addition to invasive tumors of LSI O. 1 ~ 2 cm,
