[Translational medicine of colorectal cancer]

Translational medicine is a systemic project because it is patient and clinical problems oriented, aiming at research results application, and involves multidisciplinary cooperation. Studies on molecular events in the precancerous stage, early stage and metastasis of colorectal cancer (CRC) are the CRC hot research topics currently. Investigations on the earliest molecular events can help to find out the markers which may improve the effect of CRC screening and predict CRC liver metastasis and prognosis. Based on the concept of micro environment, molecular targeted drugs to interfere with metastasis and invasion and new concepts of surgical resection margin and neoadjuvant therapy will gain recognition from clinicians.
