摘　　要：目的总结直肠癌术前分期策略的研究进展。方法对有关直肠癌术前分期方法的文献进行综述,对新近提出的多模式术前评估(multimodal preoperative evaluation,MPE)系统的相关资料进行重点总结。结果恰当选择目前存在的方法在直肠癌T分期及M分期上可以取得较高的准确性,但都不能对淋巴结转移进行准确评估。在多学科协作诊治模式下,采用MPE系统,即联合经直肠超声、计算机断层扫描技术和血清淀粉样蛋白A评估直肠癌,可取得目前较为准确的术前分期。结论MPE系统评估直肠癌术前分期具有良好的临床应用前景。Objective To summarize recent advances on preoperative staging strategies in rectal cancer. Methods Relevant references about preoperative staging strategies were collected and reviewed. The multimodal preoperative evaluation （MPE） system recently documented was focused on. Results The comparably accurate T and M stage could be achieved preoperatively by following an appropriate available method; however, the N stage＇s accuracy was still not satisfying. The MPE system, incorporating with the advantages of transrectat ultrasound, computerized tomograpby and serum amyloid A protein in a multi-disciplinary mode could display the most accurate preoperative staging for rectal cancer currently. Conclusion The MPE has potential prospects in preoperative staging of rectal cancer, and can provide the most accurate preoperative staging for rectal cancer at present.
