Hepatocellular Carcinoma, Fibrolamellar: Follow-up
Updated: Aug 22, 2007
Intervention
A percutaneous biopsy of a fibrolamellar carcinoma may be obtained for a definitive preoperative diagnosis. A percutaneous biopsy specimen is usually obtained by using either CT scanning or ultrasonographic guidance. Routine image-guided biopsy techniques are used. Fibrolamellar carcinomas are often pathologically heterogeneous, and they may contain areas of HCC or neuroendocrine differentiation. Nodular hyperplastic changes in the liver, adjacent to the tumor, may mimic FNH. Therefore, in patients with suggested fibrolamellar carcinoma, the acquisition of multiple core-needle biopsy samples is recommended to avoid misdiagnosis from sampling error. Potential complications of image-guided biopsy of fibrolamellar carcinoma are uncommon and include hemorrhage and infection.
Aggressive surgical treatment is used in patients with fibrolamellar carcinoma. The initial treatment usually involves resection of the primary tumor or liver transplantation, with en bloc resection of metastatic lymphadenopathy. Despite aggressive initial therapy, tumor recurrence within 2-12 months of resection with intent to cure is typical. Tumor recurrence almost always involves the liver, and it may be unifocal or multifocal. Intrahepatic recurrence is not necessarily located at the surgical margins. In addition, recurrent regional lymphadenopathy is often present. Distant metastases to lung or other remote sites may occur late in the course of the disease.
Surgical resection of recurrent and metastatic tumors has been shown to improve survival and is recommended. Patients with unresectable lesions can be treated with chemotherapy. Radiation therapy has not been reported to be useful.
