胃肠道恶性肿瘤术后腹腔热灌注联合全身化疗的疗效观察

1999年2月至2002年5月选择我院Ⅱ～Ⅲ期胃肠道恶性肿瘤术后患者101例，随机分为治疗组（51例）和对照组（50例），观察两组患者腹腔复发率、肝转移率及1、3、5年生存率。结果示治疗组腹腔复发率及肝转移率明显低于对照组（25．5％比50．0％，13．7％比30．0％，P〈0．05），治疗组1、3及5年的生存率明显高于对照组（P〈0．05）。提示胃肠道恶性肿瘤术后腹腔热灌注联合全身化疗，能有效降低胃肠道恶性肿瘤术后腹腔复发及肝转移，而且提高患者的生存率。

Intraperitoneal hyperthermal chemotherapy combined with general chemotherapy after surgery for malignant gastrointestinal tumors

A total of 101 patients undergoing operations for malignant gastrointestinal tumors (stage Ⅱ to Ⅲ) were enrolled and randomly assigned to receive intraperitoneal hyperthermal chemotherapy plus intravenous chemical injection (treatment group, n=51) or routine intravenous chemical injection (control group, n=50). Our results indicated that the recurrence rate and the metastatic rate in the treatment group were significantly lower than those in the control group (25.5% vs. 50.0%, 13.7% vs. 30.0%, both P< 0. 05), although the 3-and 5 year-survival rates were significantly higher (both P < 0. 05). Our data suggest that intraperitaneal hyperthermal chemotherapy plus general chemotherapy after surgery for malignant gastrointestinal tumors could effectively reduce tumor recurrence and metastases and improve long-term survival.
