Liver decompensation is a frequent cause of treatment discontinuation and prognostic factor in intermediate-advanced HCC.

INTRODUCTION AND OBJECTIVES: With the advent of new therapeutic options for patients with hepatocellular carcinoma (HCC) for intermediate or advanced stages of the Barcelona Clinic Liver Cancer (BCLC), regional real-world data regarding prognostic survival factors are of significant importance. PATIENTS AND METHODS: A multicenter prospective cohort study was conducted in Latin America including BCLC B or C patients since 15th May 2018. We report here the second interim analysis focusing on prognostic variables and causes of treatment discontinuation. Cox proportional hazard survival analysis was performed, estimating hazard ratios (HR) and 95% confidence intervals (95% CI). RESULTS: Overall, 390 patients were included, 55.1% and 44.9% were BCLC B and C at the time of study enrollment. Cirrhosis was present in 89.5% of the cohort. Among the BCLC-B group, 42.3% were treated with TACE with a median survival since the first session of 41.9 months. Liver decompensation before TACE was independently associated with increased mortality [HR 3.22 (CI 1.64;6.33); P<.001]. Systemic treatment was initiated in 48.2% of the cohort (n=188), with a median survival of 15.7 months. Of these, 48.9% presented first-line treatment discontinuation (44.4% tumor progression, 29.3% liver decompensation, 18.5% symptomatic deterioration, and 7.8% intolerance), and only 28.7% received second-line systemic treatments. Liver decompensation [HR 2.9 (1.64;5.29); P<.0001], and symptomatic progression [HR 3.9 (1.53;9.78); P=0.004] were independently associated with mortality after first-line systemic treatment discontinuation. CONCLUSIONS: The complexity of these patients, with one-third presenting liver decompensation after systemic therapies, underlines the need for multidisciplinary team management and the central role of hepatologists.

The ECHO model proved to be a useful tool to increase clinicians' self-effectiveness for care of patients with Hepatitis C in Argentina.

The ECHO model was developed to expand access to medical care for populations with HCV infection in underserved areas. We aimed to compare HCV treatment outcomes in community-based clinics with the Austral University Hospital (AUH) and to assess improvement in physician knowledge and skills. In October 2015, we established an HCV ECHO clinic at the AUH in Buenos Aires. To evaluate the impact of this programme, we conducted a prospective cohort study comparing treatment for HCV infection at the AUH with healthcare providers from different Argentinean provinces. A survey evaluating skills and competence in HCV care was administered, and results were compared. The primary endpoint was sustained virologic response (SVR) and under direct-acting antivirals. Since the implementation of ECHO clinics, a total of 25 physicians participated in at least one session (median 10.0; IQR 3.0-18.0). SVR rates (n = 437 patients) were 94.2% (95% CI 90.4-96.8) in patients treated at AUH clinic (n = 227/242) and 96.4% (95% CI 92.7-98.5) in those treated at ECHO sites (n = 188/195), with a nonsignificant difference between sites, 2.2% SVR difference (95% CI -0.24-0.06; P = 0.4). We also found a significant improvement in all the evaluated skills and abilities. Replicating the ECHO model helped to improve participants' skills in the management of HCV achieving similar SVR rates. ECHO model was demonstrated to be an effective intervention able to multiply and expand HCV treatment, a critical barrier to access to care that needs to be solved if we are committed with WHO goals to eliminate HCV by 2030.
