Radiomics Subtyping to Guide Surgery vs. Maintenance Therapy After HCC Downstaging

The goal of this observational study is to learn about the long-term treatment outcomes for patients with initially unresectable hepatocellular carcinoma (HCC) who achieve successful downstaging with the combination therapy of TACE, lenvatinib, and a PD-1 inhibitor. The main questions it aims to answer are: Can distinct disease subtypes be identified in successfully downstaged patients using radiomics and clinical data? Do these different subtypes show significant differences in long-term outcomes, such as recurrence-free survival and overall survival, after undergoing either curative-intent surgical resection or continuing maintenance therapy? Based on the identified subtypes, can the investigators objectively determine which patients are more suitable for surgical resection and which patients may benefit more from continued maintenance therapy after successful downstaging? The study will include patients who have already undergone the combination therapy as part of their regular medical care, successfully achieved tumor downstaging (making the tumor technically resectable), and subsequently received either surgical resection or continued maintenance treatment. Researchers will retrospectively analyze their existing clinical and imaging data to compare long-term outcomes between these two treatment paths based on their identified disease subtype.

Phase II-III Clinical Trial of PD1 Antibody (Toripalimab), Lenvatinib and GEMOX Neoadjuvant Treatment for Resectable Intrahepatic Cholangiocarcinoma With High-risk Recurrence Factors

A randomized controlled, multicenter, open, seamless phase II-III clinical trial is designed to target patients with resectable intrahepatic cholangiocarcinoma with high-risk recurrence factors which has extremely low postoperative recurrence-free survival. In this study, we aim to compare the prognosis in intrahepatic cholangiocarcinoma between Toripalimab combined with leventinib and GEMOX neoadjuvant treatment and the current clinical surgical treatment (traditional group).

Randomized Trial of Glutathione With Anti-PD-1 and Chemotherapy in Advanced NSCLC

Chemotherapeutic agents exert significant immunomodulatory effects by influencing tumor-infiltrating immune cells. However, the sequence and combination of chemotherapy regimens differentially modulate immune cell dynamics, ultimately impacting treatment efficacy and patient survival. Glutathione, a critical bioactive molecule, demonstrates broad potential in tumor immunotherapy. Through mechanisms such as scavenging free radicals, modulating immune cell proliferation and differentiation, and regulating cytokine expression, glutathione achieves precise modulation of immune responses to enhance immune system functionality. To investigate whether glutathione can enhance the clinical efficacy of current chemo-immunotherapy regimens in non-small cell lung cancer (NSCLC), investigators conducted this clinical study.
