经过新辅助放化,疗(neoadjuvant chemoradiotherapy),局部进展期直肠癌表现为不同程J度的退缩,甚至可以达到病理完全缓解(pathologic complete response,pCR),相关研究~([1-2])结果显示pCR率为7%~38%如果pCR患者可以在手术前被准确地甄别,那么“监测与等待”(Watch&Wait)及非于手术方案(nonoperative management.NOM)就有机会实施,进而保胃留患者的器官及其功能~([3])新辅助放化疗及全直肠系膜切除术(total mesorectal excision,TME)有效控制了直肠癌的局部复发(local recurrence,LR),LR率从大于25%降至5%~10%~([4]),但仍有约
After neoadjuvant chemoradiotherapy, locally advanced rectal cancer shows a degree of J degree of withdrawal, and even can achieve pathologic complete response (pCR), the relevant research ~ ([1-2]) Results show pCR rates between 7% and 38% If pCR patients can be accurately screened before surgery, there is an opportunity to implement “Watch & Wait” and nonoperative management. NOM, Neoadjuvant chemoradiation and total mesorectal excision (TME) effectively control the local recurrence (LR) of rectal cancer with LR rates ranging from Greater than 25% to 5% ~ 10% ~ ([4]), but still about
