由于直肠癌解剖位置的特殊性,使得外科根治性手术疗效的提高受到限制,因此人们对于化疗等辅助性手段的期待也逐渐增大.动脉灌注化疗(Transcatheter Arterial Chem-ctherapy,TAC)从50年代应用至今已有40余年历史,而作为术前辅助化疗的措施只是近十余年的事,术前动脉灌注化疗(Preoperatlve Trans catheter Arterial Chemotherapy,PTAC)作为新辅助化疗(Neoadjuvant Chemotherapy)的一种特殊手段,在直肠癌的综合治疗中已开始应用,国内开展于80年代中后期.近年来,随着导管技术和影像医学水平的不断提高,有关直肠癌PTAC的报告逐渐增多,但是关于PTAC的方法,评价标准方面的意见尚不统一,差异较大.由于欧美有关直肠癌PTAC的报告甚少,作者就国内直肠癌PTAC的问题作一综述.
Due to the particularity of rectal cancer anatomy, the curative effect of surgical radical surgery is limited, so people’s expectation for adjuvant means such as chemotherapy is gradually increasing. Transcatheter Arterial Chem-Ctherapy (TAC) from the 50’s It has been used for more than 40 years, but as a preoperative adjuvant chemotherapy is only a decade or more, Preoperatlve Trans catheter Arterial Chemotherapy (PTAC) as a special kind of neoadjuvant chemotherapy (Neoadjuvant Chemotherapy) Means have begun to be applied in the comprehensive treatment of rectal cancer, and they were developed in the middle and late 1980s in China. In recent years, with the continuous improvement of the level of catheter technology and imaging medicine, reports on rectal cancer PTAC have gradually increased, but the method of PTAC has been increasing. The opinions on the evaluation criteria are not uniform yet, and the differences are relatively large. Due to the few reports on rectal cancer PTAC in Europe and the United States, the author made a review on the problem of domestic rectal cancer PTAC.
