Professor Liu specialises in combined radiotherapy and chemotherapy for thoracic and abdominal tumours, nasopharyngeal carcinoma and prostate tumours, and has run multicentre trials of preoperative chemoradiotherapy for esophageal cancer.
His research covers radiotherapy and radiosensitisers for thoracic and abdominal tumours, concurrent chemoradiotherapy for esophageal cancer, stereotactic body radiotherapy for liver cancer, precision radiotherapy and combined treatment for prostate cancer, and combined-modality treatment of lung cancer. He has led national and provincial projects and published in journals including Journal of Clinical Oncology, JAMA Surgery and Nature Communications, and led the world’s first phase II study of definitive chemoradiotherapy combined with immunotherapy in esophageal cancer, which confirmed the efficacy and safety of that combination.
