Prophylactic Endoscopic Variceal Ligation in Patients With High-risk Esophageal Varices Receiving Atezo/Bev for HCC

Summary
The goal of this study is to evaluate whether prophylactic endoscopic variceal ligation (EVL) can prevent esophageal variceal bleeding in patients with hepatocellular carcinoma (HCC) receiving atezolizumab and bevacizumab (Atezo/Bev) therapy. The study will also assess the safety of prophylactic EVL in this population. The main question it aims to answer is: Does prophylactic EVL in high-risk varices reduce the incidence of variceal bleeding to a level similar to that of low-risk varices in HCC patients receiving Atezo/Bev? Participants will: 1. Undergo prophylactic EVL before starting Atezo/Bev therapy (within 2 weeks ± 1 week before the first dose). 2. Start Atezo/Bev therapy 2 weeks (± 1 week) after EVL. 3. Have follow-up endoscopies (EGD) one week after the 3rd, 5th, and 7th doses of Atezo/Bev. If varices improve, no additional intervention is needed. If varices persist or worsen, on-demand EVL will be performed, and Atezo/Bev will continue. This study will help determine if prophylactic EVL should be a standard strategy for managing high-risk varices in HCC patients undergoing Atezo/Bev therapy.

Interventions
1. EVL for high-risk varices will be performed by experienced endoscopists, certified in gastroenterological endoscopy, within two weeks prior to the initiation of the Atezo/Bev. 2. A follow-up EGD will be conducted one week after the Atezo/Bev #3. If any of the following criteria are met, additional EVL will not be performed, and anticancer treatment will proceed two weeks later. Otherwise, an additional on-demand EVL session will be conducted: * The esophageal varices have improved to F1 or less. * The red color sign has disappeared. 3. On-demand EVL will be considered after 5th, and 7th consecutive doses of Atezo/Bev, with EGD follow-up performed to assess eligibility. The maximum number of EVL sessions is limited to three sessions.
