术中腹腔内温热灌注化疗在胃癌治疗中的应用

目的探讨术中腹腔内温热灌注化疗对胃癌术后腹腔种植转移和生存期的影响。方法将212例进展期胃癌根治性切除术后患者随机分成观察组92例,术中予以腹腔温热灌洗化疗(丝裂霉素30mg、顺铂100mg溶于蒸馏水2000ml中,加温至43℃～45℃,灌入腹腔保留30min后吸尽)和术后氟尿嘧啶(5-FU)10～15mg/kg、丝裂霉素(MMC)0.1～0.15mg/kg、阿霉素(ADM)0.5～1mg/kg静脉化疗,每周1次,2～3次为1疗程;对照组120例,术中用蒸馏水2000ml常规冲洗,术后按上述方法单纯静脉化疗。对两组患者术后腹腔种植转移率及1、3、5年生存率进行比较。结果观察组与对照组术后2年内腹腔种植转移率分别为14.1%和37.5%(P<0.01)。观察组术后1、3和5年生存率分别为98.9%、68.5%和52.2%;对照组为95.0%、56.7%和37.5%,两组3年和5年生存率差异有统计学意义(P<0.05)。结论术中温热灌注化疗具有杀灭腹腔游离癌细胞的作用,对进展期胃癌根治术后腹腔种植转移复发有较好的防治作用,能明显提高患者术后生存率。

Application of hyperthermic intraoperative intraperitoneal chemotherapy in patients with gastric cancer

OBJECTIVE: To explore the effect of hyperthermic intraoperative intraperitoneal chemotherapy (HIIC) on the postoperative metastatic rate and survival rate of advanced gastric cancer (AGC). METHODS: In HIIC group, patients received HIIC (mitomycin C 30 mg and cisplatin 100 mg were added into 2000 ml distilled water, heated to 42 approximately 45 degrees C, perfused to abdominal cavity for 30 min and then sucked) and intravenous chemotherapy after operation (5- FU 10 approximately 15 mg/kg, mitomycin C 0.1 approximately 0.15 mg/kg, adriamycin 0.5 approximately 1 mg/kg i.v drip, once a week for 2 approximately 3 weeks). In control group, patients received intravenons chemotherapy only. The postoperative metastatic rate and survival rate (1- , 3- and 5- year) of patients were compared between 92 cases of AGC undergone HIIC and 120 cases of AGC without HIIC (control group). RESULTS: The peritoneal recurrence rates after operations occurred within two years were 14.1% and 37.5% in HIIC group and control group respectively (P < 0.01). The 1- , 3- , and 5- year survival rates in HIIC group were 98.9%, 68.5%, and 52.2% and in control group 95.0%, 56.7% and 37.5% respectively. The 3- , and 5- year survival rates were significantly different between the two the groups (P < 0.05). CONCLUSION: HIIC can kill isolated intraperitoneal cancer cells, reduce peritoneal recurrence rate after operations, raise significantly survival rate of patient, and improve the prognosis of AGC.
