RESUMO
BACKGROUND AND AIMS: The presence of dermatologic reaction as an adverse event to sorafenib treatment in patients with unresectable hepatocellular carcinoma has been indicated as a prognostic factor for survival in a recent prospective analysis. To date, this is the only clinical predictor of treatment response, which can be evaluated earlier in the treatment and, therefore, contribute to a better and more individualized patient management. MATERIAL AND METHODS: This retrospective study included 127 patients treated with sorafenib under real-life practice conditions in two hepatology reference centers in Brazil. Demographic data, disease/medical history and time of sorafenib administration as well as adverse events related to the medication were recorded in a database. RESULTS: Cirrhosis was present in 94% of patients, 85.6% were Child-Pugh A, 80.3%BCLC-C, 81% had vascular invasion and/or extrahepatic spread and 95% had a performance status 0 to 1.The median duration of treatment was 10.1 months (range: 0.1-47 months).The most common adverse event within the first 60 days of treatment were diarrhea (62.2%) and dermatological reaction (42%).The median overall survival for the cohort was 20 months, and it was higher for patients who developed dermatological reactions within the first 60 days compared to those who did not present this adverse event. CONCLUSION: This retrospective analysis showed the use of sorafenib in patients selected according to BCLC staging, and it is the first external validation of early dermatologic adverse events as a predictor of overall survival in patients with advanced hepatocellular carcinoma.

BACKGROUND: Spontaneous regression (SR) is defined as the partial or complete disappearance of a tumor, in the absence of a specific treatment. Evidence of the SR in hepatocellular carcinoma (HCC) is rare. OBJECTIVE: The authors aimed to review all the cases of SR of HCC in two reference centers of Southern Brazil, highlighting the main characteristics. METHODS: Data of all patients with HCC were retrospectively reviewed looking for the occurrence of SR in patients from two tertiary centers in Southern Brazil, in the last five years. The diagnosis of cirrhosis was established according to clinical, laboratory and imaging data, as well as upper endoscopy or histopathological examination when necessary. The diagnosis of HCC was based on typical findings according to radiologic criteria (LIRADS) or histopathological examination. Spontaneous regression was defined as a partial or complete involution of a HCC in the absence of a specific therapy. RESULTS: From all cases of HCC in the last 5 years (n=433), there were five cases of SR. Three (60%) were men, the mean age was 62.6 (50.0-76.0) years, and the etiology was HCV in 3 (60%). Complete regression was observed in three patients (60%), one patient (20%) presented partial regression, and one (20%) relapesed and died. The time of follow-up varied between 12 and 21 months. In this presentation, it was highlighted one case of SR observed after COVID-19 infection in a patient with cirrhosis. The possible mechanisms involved in this situation were reviewed, emphasizing the most common like hypoxia and immunological. There were also one patient submitted to a surgical procedure as a possible fator involved and three patients without obvious risk factors. CONCLUSION: This phenomenon will possibly contribute to a better understanding of the pathophysiological mechanisms of HCC.

⢠In compensated cirrhosis, using non-invasive methods would exempt the patient from the need of an endoscopy. ⢠The Baveno VII presented the "rule of 5" for Vibration-Controlled Transient Elastography; liver stiffness measurement ≤15 kPa and platelets >150.000/mm3 exclude clinically significant portal hypertension (CSPH), while when ≥25 kPa is highly suggestive of CSPH. ⢠Spleen stiffness measurement has been proposed as a more specific technique to predict the presence of CSPH. ⢠Elastography has gained prestige in the non-invasive evaluation of patients with advanced chronic liver disease by allowing prophylactic measures to be taken when suggesting the presence of CSPH. This is a narrative review that aims to discuss the importance of elastographic methods in the evaluation of clinically significant portal hypertension (CSPH) in cirrhotic patients, where the authors propose an algorithm for evaluating these patients. In compensated advanced chronic liver disease, the goal is to prevent the development of CSPH and, in those already with CSPH, prevent the appearance of gastroesophageal varices (GEV) and other complications of portal hypertension. In compensated cirrhosis, the prevalence of GEV is 30-40%, of which 10-20% are at risk of bleeding. Therefore, using non-invasive methods would exempt the patient from the need of an endoscopy. Hepatic Elastography is a non-invasive, safe, reproducible method, available through many techniques: Vibration-Controlled Transient Elastography (VCTE), Shear Wave Elastography (SWE) and Magnetic Resonance Elastography (MRE). The Baveno VII presented the "rule of 5" for VCTE: liver stiffness measurement (LSM) ≤15 kPa and platelets >150.000/mm3 exclude CSPH, while an LSM ≥25 kPa is highly suggestive of CSPH. Also, the "rule of 4" for SWE has been proposed: patients with ≥17 kPa could be considered as having CSPH. At last, spleen stiffness measurement (SSM) has been proposed as a more specific technique to predict the presence of CSPH. In conclusion, elastography has gained prestige in the non-invasive evaluation of patients with advanced chronic liver disease by allowing prophylactic measures to be taken when suggesting the presence of CSPH.

Cirrhosis is an emerging major cause of the development of hepatocellular carcinoma (HCC), but in non-alcoholic fatty liver disease (NAFLD), up to 50% of patients with HCC had no clinical or histological evidence of cirrhosis. It is currently challenging to propose general recommendations for screening patients with NAFLD without cirrhosis, and each patient should be evaluated on a case-by-case basis based on the profile of specific risk factors identified. For HCC screening in NAFLD, a valid precision-based screening is needed. Currently, when evaluating this population of patients, the use of non-invasive methods can guide the selection of those who should undergo a screening and surveillance program. Hence, the objective of the present study is to review the epidemiology, the pathophysiology, the histopathological aspects, the current recommendations, and novel perspectives in the surveillance of non-cirrhotic NAFLD-related HCC.

Chronic infections due to hepatitis B and hepatitis C viruses are responsible for most cases of hepatocellular carcinoma (HCC) worldwide, and this association is likely to remain during the next decade. Moreover, viral hepatitis-related HCC imposes an important burden on public health in terms of disability-adjusted life years. In order to reduce such a burden, some major challenges must be faced. Universal vaccination against hepatitis B virus, especially in the neonatal period, is probably the most relevant primary preventive measure against the development of HCC. Moreover, considering the large adult population already infected with hepatitis B and C viruses, it is also imperative to identify these individuals to ensure their access to treatment. Both hepatitis B and C currently have highly effective therapies, which are able to diminish the risk of development of liver cancer. Finally, it is essential for individuals at high-risk of HCC to be included in surveillance programs, so that tumors are detected at an early stage. Patients with hepatitis B or C and advanced liver fibrosis or cirrhosis benefit from being followed in a surveillance program. As hepatitis B virus is oncogenic and capable of leading to liver cancer even in individuals with early stages of liver fibrosis, other high-risk groups of patients with hepatitis B are also candidates for surveillance. Considerable effort is required concerning these strategies in order to decrease the incidence and the mortality of viral hepatitis-related HCC.

RESUMO Contexto: A evidência da regressão espontânea (RE) no carcinoma hepatocelular (CHC) é rara. Objetivo: Revisar todos os casos de RE de CHC em dois centros de referência do Sul do Brasil, destacando as principais características. Métodos: Os dados de todos os pacientes com CHC foram revisados retrospectivamente buscando a ocorrência de RE em pacientes de dois centros terciários do Sul do Brasil, nos últimos 5 anos. O diagnóstico de cirrose foi estabelecido de acordo com dados clínicos, laboratoriais e de imagem, além de endoscopia digestiva alta ou exame histopatológico quando necessário. O diagnóstico de CHC foi baseado em achados típicos de acordo com critérios radiológicos (LIRADS) ou exame histopatológico. A RE foi definida como uma involução parcial ou completa de um CHC na ausência de terapia específica. Resultados: Do total de casos de CHC nos últimos 5 anos (n=433), houve cinco casos de RE. Três (60%) eram homens, a média de idade foi de 62,6 (50,0-76,0) anos, a etiologia foi virus da hepatite C em 3 (60%). A regressão completa foi observada em três pacientes (60%), um paciente (20%) apresentou regressão parcial e um (20%) apresentou recidiva e evoluiu a óbito. O tempo de seguimento variou entre 12 e 21 meses. Nesta apresentação foi destacado um caso (20%) de RE observado após infecção por COVID-19 em paciente com cirrose. Foram revisados os possíveis mecanismos envolvidos nesta situação, enfatizando os mais comuns como hipóxia e imunológicos. Houve também um paciente submetido a procedimento cirúrgico como possível fator envolvido e três pacientes sem fatores de risco evidentes. Conclusão: Este fenômeno possivelmente contribuirá para uma melhor compreensão dos mecanismos fisiopatológicos do CHC.

RESUMO Trata-se de uma revisão narrativa que visa discutir a importância dos métodos elastográficos na avaliação da hipertensão portal clinicamente significativa (HPCS) em pacientes cirróticos, onde os autores propõem um algoritmo para avaliação desses pacientes. Na doença hepática crônica avançada compensada, o objetivo é prevenir o desenvolvimento de HPCS, e naqueles já com HPCS prevenir o aparecimento de varizes gastroesofágicas (VGE) e outras complicações da hipertensão portal. Na cirrose compensada, a prevalência de VGE é de 30-40% e 10-20% são varizes com risco de sangramento, portanto o uso de métodos não invasivos dispensaria o paciente de endoscopia. A elastografia hepática é um método não invasivo, seguro e reprodutível, disponível através de várias técnicas: elastografia transitória (VCTE), onda de cisalhamento (SWE) e elastografia por ressonância magnética. O Baveno VII apresentou a "regra dos 5" para VCTE: medida da rigidez hepática (LSM) ≤15 kPa e plaquetas >150.000/mm3 excluem HPCS enquanto um LSM ≥25 kPa é altamente sugestivo de HPCS. Além disso, foi proposta a "regra dos 4" para SWE: pacientes com ≥17 kPa podem ser considerados como portadores de HPCS. Por fim, a medição da rigidez do baço (SSM) foi proposta como uma técnica mais específica para prever a presença de HPCS. Em conclusão, a elastografia ganhou prestígio na avaliação não invasiva de pacientes com doença hepática crônica avançada, ao permitir a adoção de medidas profiláticas ao sugerir a presença de HPCS.
