Clinical Trial Summary

Vessels that encapsulate tumor clusters (VETC) is an invasive metastatic factor in HCC independent of the epithelial mesenchyme transition (EMT), and VETC-positive patients have a higher rate of postoperative recurrence. What can be done to improve the surgical prognosis of this group of patients needs to be continuously explored.


Clinical Trial Description

Previous studies have identified VETC as a new metastatic pattern independent of EMT that may be associated with immunosuppression as well as poor prognosis. Multiple retrospective studies find higher rates of postoperative recurrence, distant metastasis in VETC-positive patients. How to improve surgical prognosis in VETC-positive patients needs to be explored. In recent years, adjuvant immunotherapy (sintilimab) and adjuvant immunotherapy combined with targeted therapy (T+A) have been shown to be effective in improving the surgical prognosis. There are no published studies on how to improve prognosis for VETC-positive population. One of our unpublished retrospective studies found that VETC-positive patients receiving PD-1 monoclonal antibody was not effective in improving prognosis, however, PD-1 inhibitor combined with lenvatinib reduces recurrences significantly. In addition, some studies have also found that postoperative adjuvant hepatic artery infusion chemotherapy (HAIC) is also potentially useful in improving surgical prognosis. It is not clear whether triple therapy can further reduce recurrence in these tumors, which have highly aggressive characteristics. ;
