Brief 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. How to improve the prognosis of this group of patients is an urgent issue to be addressed.
Detailed 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. There are no published studies on how to improve prognosis for this 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 One of our unpublished retrospective studies found that VETC-positive patients receiving PD-1 monoclonal antibody was not effective in improving prognosis.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 monoclonal antibody in combination with PD-1 monoclonal antibody effectively reduced postoperative recurrence and improved prognosis in VETC-positive patients. Based on our previous retrospective data, this multicenter prospective cohort study was designed to further validate and explore effective therapeutics.
Interventions
Patient receives first adjuvant PD-1 monoclonal antibody 2-4 weeks postoperatively, 200 mg IV, every 21 days for a total of 9 cycles; lenvatinib is initiated orally 2-4 weeks postoperatively for 6 months.
