          Abstract

          Thyroid metastasis from hepatocellular carcinoma (HCC) is rare, and has poor prognosis. We report the case of a 62-year-old woman seen at our clinic because of the occurrence of a slightly painful abdominal mass. At that time, alpha-fetoprotein concentration was very high, reaching 49,831.7 ng/mL. Abdominal ultrasound showed a heterogeneous mass in segment IV of the liver, which was diagnosed as HCC upon MRI. The patient underwent surgical resection and histological analysis of the specimen confirmed HCC. Metastases to the thyroid were detected 17 months after liver resection. Although the presence of metastases indicates advanced disease, thyroidectomy was performed, since no other distant metastases were detected. In fact, the patient is doing well 3 years after thyroidectomy and regular imaging exams showed no tumor recurrence. Current alpha-fetoprotein concentration is 8 ng/mL. In conclusion, thyroid metastasis from HCC is uncommon and short-term survival is expected. However, surgical resection should be encouraged, especially in the case of solitary metastases.

          As metástases de carcinoma hepatocelular (CHC) em tiroide são raras e o prognóstico é ruim. Relatamos o caso de uma paciente de 62 anos de idade atendida em nossa clínica devido a uma massa abdominal levemente dolorida. Naquele momento, a concentração de alta-fetoproteína era muito alta, chegando a 49.831,7 ng/mL. O ultrassom de abdômen mostrou uma massa heterogênea no segmento IV do fígado, que foi diagnosticada como CHC por meio de ressonância magnética. A paciente foi submetida a uma ressecção cirúrgica, e a análise histológica do espécime confirmou o CHC. As metástases na tiroide foram detectadas 17 meses após a ressecção do fígado. Embora a presença de metástases indique doença avançada, a tiroidectomia foi feita porque não foram detectadas outras metástases distantes. De fato, três anos após a tiroidectomia, a paciente está bem e os exames de rotina mostraram não haver recorrência do tumor. A concentração atual de alfa-fetoproteína é de 8 ng/mL. Concluiu-se que as metástases de CHC em tiroide não são comuns e espera-se uma sobrevida curta. Entretanto, deve-se encorajar a ressecção cirúrgica, especialmente no caso de metástases solitárias.

          Natural history of hepatocellular carcinoma and current treatment options.

          Hepatocellular carcinoma (HCC) is the most frequent primary liver cancer and the most severe complication of chronic liver disease. The annual number of new cases worldwide is approximately 550,000, representing more than 5% of human cancers and is the third leading cause of cancer-related deaths. The stages of the malignancy as well as the severity of the underlying liver disease are essential factors in planning the therapeutic approach. Curative treatment options are represented mainly by surgery (ie, resection or transplantation), but most patients are not candidates for a curative option, and only palliative treatment could be given to these patients. Among palliative treatments, only chemoembolization has been proven to be effective, but other options are currently being investigated. Major risk factors for HCC are well known and are dependent on the geographic area. In Europe, the United States, and Japan, the main risk factors are liver cirrhosis, hepatitis B and C virus, alcohol, and tobacco; in contrast, in Africa and Asia, these factors are hepatitis B and C virus, tobacco use, and aflatoxin exposure. Cirrhosis from any cause is a predisposing factor for HCC and could be considered as a premalignant condition. The present concept of carcinogenesis in HCC is a multistage process. This article describes the natural history of HCC and discusses the various treatment options available at present.
