三种淋巴结分期方法对结直肠癌患者预后准确性的研究进展

Research progress in the accuracy of three lymph node staging methods for the prognosis of colorectal cancer

淋巴结转移是结直肠癌(colorectal cancer,CRC)的主要转移方式之一,也是影响患者预后的重要因素。为了对结直肠癌患者的预后进行准确评估以及制定最佳的治疗方案,需要对患者进行准确的分期。目前主要存在三种淋巴结分期方法即AJCC/UICC的N分期、阳性淋巴结比率(positive lymph node ratio,LNR)和阳性淋巴结对数比率(log odds of positive lymph nodes,LODDS)分期。现对三种淋巴结分期方法的研究进展进行综述。

Lymph node metastasis is one of the main ways of metastasis of colorectal cancer,and it is also an important factor affecting the prognosis of patients.In order to accurately assess the prognosis of patients with colorectal cancer and to develop an optimal treatment plan,accurate patient staging is required.There are currently three lymph node staging methods,which are AJCC/UICC N stage,positive lymph node ratio(LNR)and log odds of positive lymph nodes(LODDS).The research progress of three lymph node staging methods is reviewed.
