Spontaneous regression of hepatocellular carcinoma in a pure palliative care setting.

We report a case of spontaneous remission of hepatocellular carcinoma in an 84-year-old woman who was managed in our best supportive care clinic. The tumor, once relapsed regardless of the application of conventional transcatheter arterial chemoembolization and radiofrequency ablation, regressed spontaneously within 4 months. The presence of an occlusive thrombus in the portal vein feeding to the site of the tumor suggests that the reduced blood supply might have caused tumor necrosis. Furthermore, the successful eradication of hepatitis C virus maintained performance status, and good nutrition might play other roles on it.
