当前,尽管外科技术在不断改进,而文献报告较好的胃癌术后5年生存率仍低于50％(单纯早期胃癌除外)。根治性手术后最常见的胃癌复发类型是腹膜播散,这可能是手术时脱落遗留在腹腔内、或早已存在的肉眼观察不到的游离癌细胞或腹膜播散进一步发展而形成的。因此,进行胃癌腹腔脱落细胞检查,早期发现腹膜播散,对胃癌的治疗和预后估计是有一定意义的。
At present, despite the continuous improvement of surgical techniques, the 5-year survival rate of postoperative gastric cancer with good documentation is still lower than 50% (except for early-stage gastric cancer alone). The most common form of recurrence of gastric cancer after radical surgery is peritoneal dissemination. This may be due to the shedding of peritoneal deposits in the abdomen during surgery, or the development of free cancer cells or peritoneal dissemination that have not been observed by the naked eye. Therefore, the detection of abdominal exfoliated cells in gastric cancer and the early detection of peritoneal dissemination have a certain significance for the estimation of the treatment and prognosis of gastric cancer.
