近年,胃癌研究、诊治工作均已取得较大进步。但术后仍有50%～60%的病人因腹膜转移而死亡。所以预防和治疗腹膜转移已成为提高胃癌疗效的关键问题之一。我们曾对100例胃癌手术患者做了腹腔内游离癌细胞检查,发现32%的胃癌患者腹腔内存在游离癌细胞。我们对这100例胃癌进行了跟踪随访,现将长期随访结果做一整理,就腹腔内游离癌细胞对胃癌预后的影响做一初步探讨。 1 材料与方法 1985～1987年我科行手术治疗胃癌患者100例,其中胃切除术87例(根治切除67例,姑息切除20例),胃肠吻合术和开腹探查术13例。全组病例均进行了术中腹腔游离癌细胞检查,阳性者32例(32.0%)。 In recent years, great progress has been made in the research, diagnosis and treatment of gastric cancer. However, 50% to 60% of patients still died of peritoneal metastasis after surgery. Therefore, the prevention and treatment of peritoneal metastasis has become one of the key issues to improve the efficacy of gastric cancer. We have performed an intraperitoneal free cancer cell scan on 100 patients with gastric cancer and found that 32% of gastric cancer patients had free cancer cells in their peritoneal cavity. We conducted follow-up follow-up on these 100 cases of gastric cancer. We will now review the results of long-term follow-up and discuss the effects of intra-abdominal free cancer cells on the prognosis of gastric cancer. 1 Materials and Methods From 1985 to 1987, our department performed surgical treatment of 100 patients with gastric cancer, including 87 cases of gastrectomy (67 cases of radical resection and 20 cases of palliative resection), 13 cases of gastrointestinal anastomosis and laparotomy. All patients underwent intraoperative examination of free cancer cells in the abdominal cavity, 32 cases (32.0%) were positive.
