Orthotopic liver transplantation (OLT) offers the best chance for cure in the setting of unresectable hepatocellular carcinoma (HCC). A consensus statement recommends locoregional therapy (LRT) be considered in patients with HCC who are expected to wait more than 6 months for OLT to diminish dropout from the waiting list because of tumor progression. This article reviews LRT as a bridge to OLT in patients with HCC.

BACKGROUND: Hepatocellular carcinoma is one of the most common malignant tumors worldwide. Imaging techniques, specially computed tomography and ultrasound, are among the most useful diagnostic tools, although the accuracy of these methods may have a significant variability. AIMS: To determine the prevalence of hepatocellular carcinoma in cirrhotic patients undergoing orthotopic liver transplantation at "Santa Casa de Misericórdia" of Porto Alegre, RS, Brazil; to estimate the sensitivity of computed tomography and ultrasound in pretransplantation detection of hepatocellular carcinoma in this population; to correlate the radiological characteristics with anatomopathological findings. MATERIALS AND METHODS: Retrospective prevalence study. Population: adult, cirrhotic patients undergoing orthotopic liver transplantation from January 1990 to July 2003. Among the 292 transplanted patients, 31 cases of hepatocellular carcinoma were diagnosed, of which 29 were included in the study. Tumor characteristics in both ultrasound and computed tomography were compared to those observed in anatomopathological examination. RESULTS: Prevalence of hepatitis C virus infection among patients with diagnosis of hepatocellular carcinoma was 93.5%, and the prevalence of hepatocellular carcinoma among transplanted patients was 10.6%. The overall sensitivity of the imaging techniques was 70.3% for computed tomography and 72% for ultrasound. CONCLUSION: The prevalence of hepatocellular carcinoma at our institution, as well as the sensitivity of both ultrasound and computed tomography to detect such tumors at pretransplantation screening were similar to those found by other authors, while the prevalence of hepatitis C virus infection, the most common etiological agent for liver disease in our patients, is one of the highest ever reported in literature. Factors influencing hepatocellular carcinoma detection rates were: time from examination to liver transplantation; acquisition of computed tomography images during arterial phase; lesion size. Arterial phase proved to be the most useful part of computed tomography examination in this study.

Abstract Background: The ultimate goal of locoregional therapy (LRT) to the liver is to induce total tumor necrosis. Trans-arterial chemoembolization (TACE) is the mainstay bridging therapy for patients with hepatocellular carcinoma (HCC) waiting for liver transplantation (LT). However, tumor response rate is variable. The purpose of this study was to correlate HCC radiological appearance with level of tumor necrosis during explant analysis from patients undergoing LT who received pre-LT TACE. Methods: From January 2000 to December 2018, a total of 66 patients with HCC who had been treated prior to LT by means of TACE were analyzed. Diagnosis of HCC was made based on AASLD guidelines and confirmed via histopathology explant analysis. Radiologic tumor response after TACE was based on modified Response Evaluation Criteria in Solid Tumors (mRECIST). Degree of tumor necrosis was determined by histopathology analysis of liver explants. HCC radiological appearances on CT before TACE were assessed and correlated with histological findings after LT. Results: Eighty nine TACE procedures (1.35±0.67; 1-4) were performed, of which 18 were repeated TACE (27.3%) procedures. In 56.1% of the patients, ≥90% (near-complete) tumor necrosis was achieved. Concordance between mRECIST criteria and pathology was observed in 63% of the patients, with an underestimation of tumor response in 18 (27%) patients and an overestimation in 6 (9.1%). Near-complete tumor necrosis upon pathological analysis was associated with tumor hyper-enhancement in the arterial phase (P=0.002), “typical tumor enhancement” (P=0.010) and smooth tumor margins (p=0.011). The multivariate analysis showed that well circumscribed HCCs with smooth margins and arterial hyper-enhancement independently correlated with post-TACE near-complete histological tumor necrosis. Conclusion s : The well circumscribed HCC lesions with arterial hyper-enhancement are more susceptible to TACE than lesions with arterial phase iso or hypo-enhancement and lesions with infiltrative appearance. Pre-TACE CT imaging may ease the selection of an optimal treatment strategy for bridging patients with HCC to liver transplantation.
