Total Mesorectal Excision(TME) With Lateral Lymph Node Dissection Versus TME After Neoadjuvant Chemo-radiotherapy
Total Mesorectal Excision(TME) With Lateral Lymph Node Dissection Versus TME After Neoadjuvant Chemo-radiotherapy of Lower Rectal Cancer With Suspected Local Lymph Node Metastasis
Sixth Affiliated Hospital, Sun Yat-sen University
250 participants
Dec 17, 2018
INTERVENTIONAL
Conditions
Summary
Treatment for Low rectal cancer, especially in patients with regional lymph node metastasis are quite different between Japanese guideline (JSCCR) and western countries' guideline (NCCN, ESMO). While Japanese scholars advocate total mesorectal excision (TME) plus lateral lymph node dissection (LLND), European and American scholars advocate TME alone after Neoadjuvant Chemo-radiotherapy (nCRT), without the need of LLND. Accordingly, this clinical trial is designed to directly compare the efficacy and safety of these two treatment strategies for low rectal cancer with regional lymph node metastasis. It will provide high-level clinical evidence for the treatment of low rectal cancer with suspected local lymph node metastasis
