Résumé

More than 18 million people in 188 countries have been diagnosed as having coronavirus disease (COVID-19), and COVID-19 has been responsible for more than 600,000 deaths worldwide. Brazil is now the second most affected country globally. Faced with this scenario, various public health measures and changes in the daily routines of hospitals were implemented to stop the pandemic. Patients with hepatocellular carcinoma (HCC) are at an increased risk for severe COVID-19 as they present with two major diseases: cancer and concomitant chronic liver disease. The COVID-19 pandemic can significantly impact the management of HCC patients from diagnosis to treatment strategies. These patients need special attention and assistance at this time, especially since treatment for tumors cannot be delayed in most cases. The aim of this guideline was to standardize the management of HCC patients during the COVID-19 pandemic. This document was developed, on the basis of the best evidence available, by a multidisciplinary team from Instituto do Câncer do Estado de São Paulo (ICESP), and Instituto Central of the Hospital das Clínicas da Universidade de São Paulo (HC-FMUSP), which are members of the São Paulo Clínicas Liver Cancer Group.

Résumé

OBJECTIVES: Fibrolamellar hepatocellular carcinoma is a rare primary malignant liver tumor that differs from conventional hepatocellular carcinoma in several aspects. The aim of this study was to describe the clinical, surgical and histopathological features of fibrolamellar hepatocellular carcinoma and to analyze the factors associated with survival. METHODS: We identified 21 patients with histopathologically diagnosed fibrolamellar hepatocellular carcinoma over a 22-year period. Clinical information was collected from medical records and biopsies, and surgical specimens were reviewed. RESULTS: The median age at diagnosis was 20 years. Most patients were female (67%) and did not have associated chronic liver disease. Most patients had a single nodule, and the median tumor size was 120 mm. Vascular invasion was present in 31% of patients, and extra-hepatic metastases were present in 53%. Fourteen patients underwent surgery as the first-line therapy, three received chemotherapy, and four received palliative care. Eighteen patients had “pure fibrolamellar hepatocellular carcinoma,” whereas three had a distinct area of conventional hepatocellular carcinoma and were classified as having “mixed fibrolamellar hepatocellular carcinoma.” The median overall survival was 36 months. The presence of “mixed fibrolamellar hepatocellular carcinoma” and macrovascular invasion were predictors of poor survival. Vascular invasion was associated with an increased risk of recurrence in patients who underwent surgery. CONCLUSION: Fibrolamellar hepatocellular carcinoma was more common in young female patients without chronic liver disease. Surgery was the first therapeutic option to achieve disease control, even in advanced cases. Vascular invasion was a risk factor for tumor recurrence. The presence of macrovascular invasion and areas of conventional hepatocellular carcinoma were directly related to poor survival. .
