摘要
目的分析总结结直肠癌肝转移新辅助化疗的疗效,探讨以肝动脉导管化疗栓塞(TACE)为基础的新辅助化疗在综合治疗中的作用。方法新辅助治疗前、治疗后2周超声检查,记录肿瘤大小、血流分布及频谱、平均血流速度和血管阻力指数。5cm以上的病灶,按照以下6步程序进行治疗和评价:(1)B超或CT;(2)TACE;(3)TACE后B超;(4)手术切除;(5)6疗程SVC;(6)B超或CT评价效果。结果42例行肝转移灶切除前新辅助治疗,其中15例行全身化疗,27例行肝动脉导管化疗栓塞(TACE),DSA显示25例显示有门静脉血供,18例显示有肝动脉分支血液供瘤。B超示瘤体中央及周边血流丰富,瘤体内动脉PSV0.87m/s,R10.83,TACE后1周PSV0.63m/s,R10.85(P%0.05)周边血流明显减少。病理显示瘤体中央有明显区域性坏死,周边部分有淋巴细胞为主的慢性炎症反应。经TACE为新辅助化疗的病例随访时间为14~27个月,全部无瘤生存。1年生存率为92.9%。结论TACE作为肝转移灶的新辅助化疗首选方案,能有效降低肝转移灶的血液供应,促使肿瘤坏死,为手术的彻底切除及后续的预防再复发和转移有一定作用。
Objective To assess the therapeutic efficacy of comprehensive management and preoperative chemotherapy of liver metastasis of colorectal cancer. Methods Two weeks before and after the neoadjuvant chemotheray, its therapeutic efficacy was assessed by: 1)BUS or CT, 2)TACE, 3) BUS after TACE,4)Resection,5)6 courses of SVC,6)BUS or CT. Results BUS displayed that PSV was 0.87m/s and RI 0.83 in internal artery of tumor. After TACE for 1 week, PSV was 0.63m/s and RI 0.85 (P〈0.05). Pathological examination showed that the regional necrosis and lymphoma repose were signiflcantly different. All the patients undergoing the TACE were alive without tumors and the 1 year survival rate was 92.9%. Conclusion The neoadjuvant chemotherapy by TACE can decrease blood supply and increases necrosis for tumors.
