直肠癌患者新辅助治疗后有局部复发和远处转移的可能性,肿瘤消退分级(TRG)的概念由此被提出。但该定义尚无统一的标准且未考虑淋巴结浸润的情况,故Li J等人提出了新肿瘤消退分级(NTRG)以评估患者的预后。该研究对2004年9月至2011年10月期间接受了新辅助治疗和根治手术的局部进展期直肠癌患者进行了回顾性分析,依据同时考虑了肿瘤消退分 Rectal cancer patients after neoadjuvant therapy have the possibility of local recurrence and distant metastasis, the concept of tumor regression classification (TRG) was proposed. However, there is no uniform standard for this definition and lymph node infiltration is not considered. Therefore, Li J et al. Proposed a new tumor regression classification (NTRG) to assess the patient’s prognosis. The study retrospectively analyzed patients with locally advanced rectal cancer who received neoadjuvant therapy and radical surgery between September 2004 and October 2011, based on a combination of tumor regression
