侵及浆膜的胃肠道癌肿,手术时癌肿被挤压、标本切缘及离断血管或淋巴管时的癌细胞脱落,均可导致癌细胞腹腔内种植.即使施行根治性肿瘤切除,仍有半数以上患者死于术后复发.因此清除和杀灭脱落于腹腔的癌细胞,对防止或降低术后癌肿复发有重要意义.1 材料和方法 我科自1990年以来,对164例胃肠道癌肿施行根治性切除.56例术中及病理证实癌肿侵及浆膜,将其随机分为全身化疗和腹腔内灌洗化疗组.前组42例,腹腔内灌洗化疗组14例.除腹腔内灌洗化疗组1例胃恶性淋巴瘤行全胃切除外,其余病
Gastrointestinal squamous cell carcinoma that invades the serosa, when the cancer is squeezed during surgery, the cancerous margin at the cutting edge of the specimen, and the detachment of blood vessels or lymphatic vessels, can cause cancer cells to grow in the abdominal cavity. Even if a radical tumor is removed There are still more than half of the patients died of postoperative recurrence. Therefore, the removal and killing of cancer cells shed in the abdominal cavity are important for preventing or reducing postoperative recurrence of cancer. 1 Materials and Methods Our department has been working on 164 since 1990. Gastrointestinal cancer was treated with radical resection. 56 cases of intraoperative and pathologically confirmed cancer invasion and serosa were randomly divided into systemic chemotherapy and intraperitoneal lavage chemotherapy group. The former group of 42 cases, intraperitoneal lavage chemotherapy Group of 14 cases. In addition to intraperitoneal lavage chemotherapy group 1 case of gastric malignant lymphoma underwent total gastrectomy, other diseases
