title: Stereotactic radiotherapy of the liver: a bridge to transplantation stereotactic radiotherapy of the liver: a bridge to transplantation.
abstract: Patients with hepatocellular carcinoma (HCC) have limited curative therapeutic options. In North America, liver transplantation is one of the most commonly used curative therapies. Many potential transplant patients will be treated with another therapeutic modality to prevent local disease progression while awaiting organ donation. We present the case of 60-years old male diagnosed with HCC and awaiting liver transplantation. Prior to registration on the transplant list, the patient had a significant increase of his serum alpha-fetoprotein level. Due to his vascular anatomy and tumor location, he was not a candidate for more standard local ablative therapies. He was thus offered stereotactic radiotherapy as a bridge to liver transplantation. He received 50 Gy in 5 fractions using respiratory gating. Following this, he had a complete radiological and serological response without worsening of his baseline Child-Pugh class C cirrhosis. Following transplant, 13 months later, pathological examination of the liver explant revealed only scarring at the site of radiation. This case illustrated the fact that hepatic stereotactic radiotherapy is a promising and safe treatment for patients with HCC. In selected patients, it can be a bridge to transplantation and, on its own, has the potential to induce complete pathological response in non-surgical candidates.
