Abstract:

Colorectal cancer(CRC)is the third most common malignant tumor in the world and the second most common cause of cancer death.Surgery is the main treatment.Because the symptoms of colorectal cancer are not obvious in the early stage, most patients have missed the opportunity of surgery.For patients with resectable tumors, neoadjuvant chemotherapy is used to improve local control rate and overall survival rate.For patients with unresectable tumors, transformation therapy is used to transform them into resectable state, followed by surgical resection.Neoadjuvant chemotherapy is suitable for patients with tumor in middle stage or difficult to be resected as well as difficult to be removed completely.It can reduce the tumor stage and make the tumor shrink so as to facilitate subsequent surgery and radiotherapy.Domestic and foreign studies have found that preoperative neoadjuvant chemotherapy contributes to the improvement of surgical resection rate and prolongs postoperative survival of patients.This article reviews the application principles, efficacy evaluation, clinical benefits and risks of neoadjuvant chemotherapy in the treatment of colorectal cancer.

Key words: Colorectal cancer, Neoadjuvant chemotherapy, Hepatic metastases, Multidisciplinary comprehensive treatment
