Clinical evaluation of rectal cancer after neoadjuvant chemoradio-therapy / 中国肿瘤临床

Rectal cancer is a common type of malignant tumor, with increasing incidence over the previous years. Total mesorec-tal excision is the most important treatment for rectal cancer. Advanced rectal cancer presents high local recurrence rate and low sphinc-ter preservation rate. For locally advanced rectal cancer, neoadjuvant chemoradiotherapy is the optimal management strategy. In this re-gard, clinicians have focused on investigating the clinical effects of rectal cancer after neoadjuvant chemoradiotherapy. Prediction and evaluation of rectal cancer after neoadjuvant therapy can be used to determine further necessary treatments, effect on quality of life, and survival time of patients.
