胃癌浆膜侵犯与腹腔内游离癌细胞的相互关系

RELATIONSHIP BETWEEN INTRAPERITONEAL FBEE CANCER CELLS AND SEROSAL INVASION OF GASTRIC CANCER

采用上腹腔冲洗法，对６６例胃癌患者进行了腹腔内游离癌细胞检查，其游离癌细胞阳性率与肿瘤浸润深度呈正相关，Ｓ２及Ｓ３组阳性率分别为３３．３％和６５．２％，并与浆膜受侵面积密切相关，受侵浆膜面积大于２０ｃｍ２组阳性率高达７３．３％。本文将癌底浆膜外观分为Ⅰ、Ⅱ、Ⅲ型，其阳性率分别为４７．３％，１６．７％，０％。本文结果认为：腹腔内游离癌细胞与胃癌侵润深度，受浸浆膜面积及癌底浆膜外观密切相关。

The relationship between intraperitoneal free cancer cells(FCC)and serosal invasionwas examined in 66 gastric cancer patients.The results were as follows : FCC were closelyassociated with the depth of wall invasion,gross apperance of serosa and the area of serosalinvasion;the deeper the wall invasion, the higher the positive rate of FCC;and the larger thearea of serosal invasion, the higher also the positive rate of FCC. The positive rate was 65.2%in patients with cancer extending to other neighboring organs,73.3% in patients with anarea of serosal invasion greater than 20cm2, and 47.3% in patients with type I grossappearance of serosa.
