Summary

Hepatocellular carcinoma (HCC) is one of the most common types of primary liver cancer worldwide, characterized by complex and variable disease progression and significant treatment challenges. Among HCC patients, tumor budding (TB) is associated with a high risk of postoperative recurrence, significantly impacting patient prognosis. Even in the current HCC pathological diagnosis "gold standard" of MVI-negative patients, TB retains excellent prognostic predictive value. TB cells reside within the peritumoral stroma, where dense collagen fibers restrict the efficacy of therapeutic agents including chemotherapy, immunotherapy, and targeted therapies, making it difficult for single-agent treatments to effectively eliminate TB. Therefore, specific treatment strategies should be considered for TB-positive patients to improve survival outcomes and reduce the risk of tumor recurrence. To address this clinical challenge, this study aims to clarify the prognostic impact of combining collagen degradation therapy with targeted therapy in TB-positive HCC patients. Through a single-arm trial (postoperative targeted therapy + collagen degradation therapy), investigators explore the clinical efficacy and prognostic indicators of this combination approach, seeking the optimal treatment strategy for TB-positive HCC patients. Collagen degradation therapy facilitates drug delivery to tumor-bottle lesions by degrading collagen barriers, while targeted therapy specifically intervenes against cancer cells. Their combination holds promise for synergistic effects and enhanced therapeutic outcomes. This study aims to preliminarily assess the impact of this dual approach on prognosis, providing evidence for personalized treatment strategies. The findings of this research hold promise for delivering new breakthroughs in the treatment of TB-positive HCC patients, improving their quality of life and survival rates, and providing robust support for future clinical practice.

Conditions

• Carcinoma, Hepatocellular

Interventions

Type	Name	Description
DRUG	Lenvatinib + losartan	Patients will receive a combination of lenvatinib and losartan at the same time after surgery for treatment cycles once daily (lenvatinib and losartan). Adjuvant therapy will be started within 2-6 weeks after surgery for a period of time to evaluate the effect of different treatment regimens on reducing tumor recurrence and improving survival. lenvatinib: orally once daily according to standard dosing guidelines, starting postoperatively. losartan: 50mg losartan potassium tablets orally once daily starting postoperatively.
