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.

Objective:To assess the prognosis of sinonasal adenoid cystic carcinoma with hard palatine invasion treated by transnasal endoscopic total maxillectomy. Methods:Clinical data of twenty-six patients with sinonasal adenoid cystic carcinoma invading hard palatine treated by transnasal endoscopic total maxillectomy between May 2014 and December 2020 was analyzed retrospectively. Survival rate, local recurrence and distant metastasis were analyzed using Kaplan-Meier method. Cox regression was used to investigate the prognosis factors. Masticatory function after maxillectomy has also been assessed using the questionnaire of patients' satisfaction about masticatory function. Results:Margins in 8 patients（30%） were positive. The median time of follow-up was 38 months（6 to 85 months）. Twenty-five patients recurred. Four patients died of distant metastasis. The 5-year overall survival rate and relapse-free survival rate was 79.5% and 89.1%, respectively. Independent predictors of outcome on multivariate analysis were positive margin（P=0.018）, recurrence（P=0.006） and distant metastasis（P=0.04）. Conclusion:Transnasal endoscopic total maxillectomy could be performed for the treatment of the sinonasal adenoid cystic carcinoma with hard palatine invasion. Positive margin, local recurrence and distant metastasis were important predictors for patients' prognosis.
