title: Spontaneous complete regression of multiple metastases of hepatocellular carcinoma: A case report.
abstract: Spontaneous regression of cancer is a partial or complete disappearance of malignant tumor without specific treatment. Spontaneous regression of hepatocellular carcinoma (HCC) is a rare condition, and the mechanism underlying it is unclear. This report presents a rare case of spontaneous complete regression of HCC, as revealed by tumor markers and imaging studies. A 64-year-old Korean male patient with hepatitis B virus-associated chronic hepatitis presented with HCC. The patient had undergone right lobectomy of the liver but the cancer recurred with multiple lung and adrenal metastases after 14 months. The patient received palliative cytotoxic chemotherapy. However, there was no clinical benefit and the disease progressed. It was decided to discontinue anticancer therapy and administer only supportive care. After approximately six months, the symptoms disappeared and the HCC had completely regressed. The patient remains alive over five years after recurrence.
