Esophageal Varices Prophylaxis in Hepatocellular Carcinoma Treated With Atezolizumab and Bevacizumab

The goal of this prospective cohort study is to evaluate the progression of esophagogastric varices in patients treated with atezolizumab-bevacizumab. Assess the efficacy of primary prophylaxis of small esophageal varices with no risky signs and shortening endoscopic follow-up time intervals to reduce the risk of variceal hemorrhage. Researchers will assess the progression of esophageal varices (EVs) with no bleeding stigmata in patients treated with atezolizumab-bevacizumab therapy at 3, 6, 9, and 12 months with endoscopic examination. Evaluate the effect of shortening the endoscopic follow-up intervals to reduce the risk of variceal bleeding in patients treated with atezolizumab-bevacizumab therapy. Researchers will also assess the efficacy of variceal band ligation in small varices without bleeding stigmata before starting atezolizumab-bevacizumab therapy to reduce the progression of EVs. Participants will undergo history-taking, clinical examination, laboratory investigations, Triphasic CT abdomen with contrast or MRI (for evaluation of tumor site, size and number), abdominal ultrasonography, and upper endoscopy (within 6 months before beginning of systemic therapy and followed up after 3, 6, 9, and 12 months).
