ABSTRACT
Therapeutic goal for locally advance rectal cancer (LARC) patients includes long-term survival and function preservation of pelvic organs. During the recent two decades, treatment strategy for LARC is gradually shifing to minimally invasive surgery, even avoiding a major surgery. "Watch and wait (W&W)" strategy is effective in dramatically decreasing surgical trauma and significantly improving preservation of defecation, urination and sexual function. Total neoadjuvant therapy (TNT) shifts all or part of adjuvant chemotherapy to the neoadjuvant phase and has showed obvious advantage in tumor shrinkage and complete clinical response (cCR) achievement. This article will summarize the transition of treatment strategy of LARC towards W&W from standard treatment. After more than ten years of development, both NCCN and ESMO guidelines recommend stratified neoadjuvant treatment considerations based on distinct risk classifications and especially suggest TNT for LARC patients with advanced diseases, which affirms the value of TNT in tumor shrinkage. Although accumulating data show that pelvic control and organ preservation using W&W strategy after cCR is equal or non-inferior to standard surgery, impact on long-term survival still needs prospective randomized controlled study; no consensus has been achieved for the detail of the W&W strategy. Thus W&W strategy is suggested to applied in hospitals specialized in the treatment of rectal cancer within the framework of multiple disciplinary treatment. In view of special medical conditions of our country, we still need to accumulate more experience and data of W&W strategy for rectal cancer patients with appeals for sphincter preservation and actively participate in international researches.
