Study Arms:
- LLND+TME group (Type: EXPERIMENTAL): advanced rectal cancer patients after neoadjuvant chem-radiation with suspicious lateral lymph nodes involvement undergo lateral lymph node dissection and total mesorectal excision(LLND+TME)
- TME group (Type: NO_INTERVENTION): advanced rectal cancer patients after neoadjuvant chem-radiation with suspicious lateral lymph nodes involvement undergo total mesorectal excision (TME)solely, without LLND

Based on this trial design, predict the completion outcome and termination type (if applicable).
