Conversion Therapy

Conversion therapy for unresectable intermediate-advanced hepatocellular carcinoma (uHCC) has evolved from systemic therapy to combined local-systemic approaches, but current regimens still have limited surgical conversion rates. This prospective, single-arm phase II study evaluates a combination regimen of PD-1 inhibitor (sintilimab) plus CTLA-4 inhibitor (ipilimumab N01), bevacizumab biosimilar, and HAIC for patients with initially unresectable intermediate-advanced HCC. The primary goal is to achieve a higher surgical conversion rate with manageable safety

The goal of this phase 2 trial is to evaluate the efficacy and safety of tislelizumab combined with intravenous chemotherapy and bronchial artery chemoembolization (BACE) as conversion therapy for patients with initially unresectable stage IIIA-IIIB non-small cell lung cancer (NSCLC). The main questions it aims to answer are: * What is the 1-year event-free survival (EFS) rate with this treatment? * Can this treatment improve tumor response and the chance of curative-intent resection? * What adverse events occur during treatment? Participants will receive tislelizumab, intravenous chemotherapy, and BACE for up to 4 cycles. Tumor response and resectability will be evaluated by imaging and multidisciplinary team (MDT) assessment every 2 cycles. Participants who become resectable may undergo surgery followed by postoperative treatment per protocol. Participants who remain unresectable after 4 cycles will receive guideline-recommended chemoradiotherapy followed by tislelizumab consolidation. Regular follow-up will be performed for efficacy and safety assessment.

This project aims to conduct a prospective, multicenter, randomized controlled clinical trial. The study plans to enroll 270 patients with locally advanced iCCA who have successfully undergone GOLP conversion therapy. Participants will be randomized at a 1:2:2 ratio into three arms: Control Arm (continued medication), Direct Surgery Arm, and TDTP-RECIST Assessment Arm. The primary endpoint is Overall Survival (OS).
