Current Status of Immunotherapy for Metastatic Colorectal Cancer

Abstract

Colorectal cancer (CRC) is one of the most common malignant tumors in the world, which is also the main death cause of cancer patients. Surgery, radiotherapy and chemotherapy can improve the prognosis of CRC patients. However, late recurrence and distant metastatic diseases cannot be cured, which will result in poor prognosis. With the cross penetration of molecular biology, oncology and immunology, the immunotherapy has made a huge breakthrough and has become an important means of tumor therapy. This article summarizes the immunotherapy of metastatic CRC at home and abroad in recent years.
