Moderate-dose radiotherapy combined with Tislelizumab for liver cancer with tumor thrombosis

Phase II Study of Moderate-dose Hypofractionated Radiotherapy Combined With Tislelizumab for Hepatocellular Carcinoma With Diffuse Tumor Thrombosis Involved Both Left and Right Liver

Phase 2 Interventional Cancer Institute and Hospital, Chinese Academy of Medical Sciences · NCT06233981

This study is testing if combining a specific type of radiation therapy with an immunotherapy drug can help people with liver cancer and blood clots in their tumors feel better and live longer.

What this trial studies

This clinical trial investigates the effectiveness of moderate-dose hypofractionated intensity-modulated radiotherapy combined with Tislelizumab in patients with hepatocellular carcinoma (HCC) that has diffuse tumor thrombosis. The study includes patients with specific liver tumor volume criteria and administers radiotherapy alongside Tislelizumab, an immunotherapy agent, to enhance treatment outcomes. Follow-up examinations will assess overall survival and response rates, with maintenance therapy options available if tolerated. The trial aims to provide insights into the combined treatment's efficacy in improving patient outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18-90 with confirmed hepatocellular carcinoma and portal or hepatic vein thrombosis, meeting specific liver volume criteria.

Not a fit: Patients who have previously received immune checkpoint inhibitors or have significant comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve overall survival rates for patients with advanced liver cancer and tumor thrombosis.

How similar studies have performed: While there have been studies exploring radiotherapy and immunotherapy combinations, this specific approach is novel and has not been extensively tested in this patient population.
