Spontaneous regression of advanced hepatocellular carcinoma following COVID-19 infection and vaccination: a case report and review of literature.

This unique case highlights SR of advanced HCC following COVID-19 infection, raising intriguing questions about the interplay between viral infections, vaccinations, and cancer outcomes. The patient's response in the absence of systemic therapy further underscores the complexity of HCC management and prompts further investigation into the potential immunomodulatory effects of viral infections and vaccinations on cancer regression. Understanding these interactions could have implications for tailoring treatment approaches and improving outcomes in patients with advanced HCC.
