Ninety percent of malignant tumor treatment failure is due to post-operative metastasis and recurrence. Paget's "seed and soil" in 1889 and Ewing's "tumor metastatic fluid dynamics" in 1928 are the basic scientific concepts of metastasis. With the advanced molecular biological technology combined with the translational medicine research, possible or potential metastatic "seed"-tumor stem cells or stemness cells can be screened. In recent years, study on the "tumor derived exosome" raised the concept of pre-metastatic niche and progenitor metastasis. On the other hand, associated methodology and technology for screening and detection of the exosome had been established, which provides feasible methods for screening, prediction and individual therapy. It will be the new era for cancer prevention and intervention in translational medicine area.

Adenoid cystic carcinoma usually occurs in the salivary glands of the head and neck. It is a malignant tumor with a high degree of malignancy, resistance to radiotherapy and chemotherapy and poor prognosis. The clinical course of adenoid cystic carcinoma is slow and easy to be misdiagnosed. The main diagnosis and treatment means are individualized and precise treatment under the multi-disciplinary consultation mode, that is, surgical treatment and radiotherapy and chemotherapy. Adenoid cystic carcinoma is prone to relapse and hematologic metastasis, and the traditional radiotherapy and chemotherapy based therapies have not achieved satisfactory efficacy in the past three decades. How to detect, diagnose and treat early is an urgent task faced by clinicians.
