RESUMO

INTRODUCTION AND OBJECTIVES: Failures at any step in the hepatocellular carcinoma (HCC) surveillance process can result in HCC diagnostic delays and associated worse prognosis. We aimed to estimate the prevalence of surveillance failure and its associated risk factors in patients with HCC in Argentina, considering three steps: 1) recognition of at-risk patients, 2) implementation of HCC surveillance, 3) success of HCC surveillance. METHODS: We performed a multi-center cross-sectional study of patients at-risk for HCC in Argentina seen between10.01.2018 and 10.30.2019. Multivariable logistic regression analysis was used to identify correlates of surveillance failure. RESULTS: Of 301 included patients, the majority were male (74.8%) with a mean age of 64 years old. At the time of HCC diagnosis, 75 (25%) patients were unaware of their diagnosis of chronic liver disease, and only 130 (43%) patients were under HCC surveillance. Receipt of HCC surveillance was significantly associated with follow-up by a hepatologist. Of 119 patients with complete surveillance, surveillance failure occurred in 30 (25%) patients. Surveillance failure was significantly associated with alpha fetoprotein ≥20 ng/mL (OR 4.0, CI 95% 1.43-11.55). CONCLUSIONS: HCC surveillance failure was frequent in all the evaluated steps. These data should help guide strategies to improve the implementation and results of HCC surveillance in our country.

RESUMO

BACKGROUND: Hepatocellular carcinoma (HCC) represents the sixteenth most frequent cancer in Argentina. The rise of new therapeutic modalities in intermediate-advanced HCC opens up a new paradigm for the treatment of HCC. AIM: To describe real-life treatments performed in patients with intermediate-advanced HCC before the approval of new systemic options. METHODS: This longitudinal observational cohort study was conducted between 2009 and 2016 in 14 different regional hospitals from Argentina. Included subjects had intermediate-advanced Barcelona Clinic Liver Cancer (BCLC) HCC stages (BCLC B to D). Primary end point analyzed was survival, which was assessed for each BCLC stage from the date of treatment until last patient follow-up or death. Kaplan Meier survival curves and Cox regression analysis were performed, with hazard ratios (HR) calculations and 95% confidence intervals (95%CI). RESULTS: From 327 HCC patients, 41% were BCLC stage B, 20% stage C and 39% stage D. Corresponding median survival were 15 mo (IQR 5-26 mo), 5 mo (IQR 2-13 mo) and 3 mo (IQR 1-13 mo) (P < 0.0001), respectively. Among BCLC-B patients (n = 135), 57% received TACE with a median number of 2 sessions (IQR 1-3 sessions). Survival was significantly better in BCLC-B patients treated with TACE HR = 0.29 (CI: 0.21-0.40) than those without TACE. After tumor reassessment by RECIST 1.1 criteria following the first TACE, patients with complete response achieved longer survival [HR = 0.15 (CI: 0.04-0.56, P = 0.005)]. Eighty-two patients were treated with sorafenib, mostly BCLC-B and C (87.8%). However, 12.2% were BCLC-D. Median survival with sorafenib was 4.5 mo (IQR 2.3-11.7 mo); which was lower among BCLC-D patients 3.2 mo (IQR 2.0-14.1 mo). A total of 36 BCLC-B patients presented tumor progression after TACE. In these patients, treatment with sorafenib presented better survival when compared to those patients who received sorafenib without prior TACE [HR = 0.26 (CI: 0.09-0.71); P = 0.013]. CONCLUSION: In this real setting, our results were lower than expected. This highlights unmet needs in Argentina, prior to the introduction of new treatments for HCC.

RESUMO

BACKGROUND: Biannual ultrasound (US) is recommended as the clinical screening tool for hepatocellular carcinoma (HCC). The effectiveness of surveillance according to the place where US is performed has not been previously reported. AIMS: To compare the effectiveness of US performed in the center responsible for follow-up as opposed to US proceeding from centers other than that of follow-up. METHODS: This is a multicenter cohort study from Argentina. The last US was categorized as done in the same center or done in a different center from the institution of the patient's follow-up. Surveillance failure was defined as HCC diagnosis not meeting Barcelona Clinic Liver Cancer (BCLC) stages 0-A or when no nodules were observed at HCC diagnosis. RESULTS: From 533 patients with HCC, 62.4% were under routine surveillance with a surveillance failure of 38.8%. After adjusting for a propensity score matching, BCLC stage and lead-time survival bias, surveillance was associated with a significant survival benefit [HR of 0.51 (CI 0.38; 0.69)]. Among patients under routine surveillance (n = 345), last US was performed in the same center in 51.6% and in a different center in 48.4%. Similar rates of surveillance failure were observed between US done in the same or in a different center (32% vs. 26.3%; P = 0.25). Survival was not significantly different between both surveillance modalities [HR 0.79 (CI 0.53; 1.20)]. CONCLUSIONS: Routine surveillance for HCC in the daily practice improved survival either when performed in the same center or in a different center from that of patient's follow-up.

RESUMO

BACKGROUND AND AIM: Adherence to the Barcelona Clinic Liver Cancer (BCLC) staging algorithm for the treatment of hepatocellular carcinoma is challenging in the daily practice. We aimed to analyze adherence to BCLC along with its effect on patient survival. PATIENTS AND METHODS: A cohort study was conducted in 14 hospitals from Argentina including patients with newly diagnosed hepatocellular carcinoma (2009-2016). Adherence was considered when the first treatment was the one recommended by the BCLC. RESULTS: Overall, 708 patients were included. At diagnosis, BCLC stages were as follows: stage 0 4%, A 43%, B 22%, C 9% and D 22%. Overall, 53% of the patients were treated according to BCLC, 24% were undertreated, and 23% overtreated. Adherence to BCLC increased to 63% in subsequent treatments. Independent factors associated with adherence to BCLC were the presence of portal hypertension [odds ratio: 1.63; 95% confidence interval (CI): 1.11-2.39] and BCLC stage C (odds ratio: 0.32; 95% CI: 0.12-0.72). In a multivariable model adjusting for portal hypertension and BCLC stages, adherence to BCLC showed improved survival (hazard ratio: 0.67; 95% CI: 0.52-0.87). CONCLUSION: Adherence to BCLC represents a challenge in the daily practice, with almost half of the patients being treated accordingly, showing that the decision-making process should be tailored to each individual patient.

RESUMO

AIM: To investigate any changing trends in the etiologies of hepatocellular carcinoma (HCC) in Argentina during the last years. METHODS: A longitudinal cohort study was conducted by 14 regional hospitals starting in 2009 through 2016. All adult patients with newly diagnosed HCC either with pathology or imaging criteria were included. Patients were classified as presenting non-alcoholic fatty liver disease (NAFLD) either by histology or clinically, provided that all other etiologies of liver disease were ruled out, fatty liver was present on abdominal ultrasound and alcohol consumption was excluded. Complete follow-up was assessed in all included subjects since the date of HCC diagnosis until death or last medical visit. RESULTS: A total of 708 consecutive adults with HCC were included. Six out of 14 hospitals were liver transplant centers (n = 484). The prevalence of diabetes mellitus was 27.7%. Overall, HCV was the main cause of liver disease related with HCC (37%) including cirrhotic and non-cirrhotic patients, followed by alcoholic liver disease 20.8%, NAFLD 11.4%, cryptogenic 9.6%, HBV 5.4% infection, cholestatic disease and autoimmune hepatitis 2.2%, and other causes 9.9%. A 6-fold increase in the percentage corresponding to NAFLD-HCC was detected when the starting year, i.e., 2009 was compared to the last one, i.e., 2015 (4.3% vs 25.6%; P < 0.0001). Accordingly, a higher prevalence of diabetes mellitus was present in NAFLD-HCC group 61.7% when compared to other than NAFLD-HCC 23.3% (P < 0.0001). Lower median AFP values at HCC diagnosis were observed between NAFLD-HCC and non-NAFLD groups (6.6 ng/mL vs 26 ng/mL; P = 0.02). Neither NAFLD nor other HCC etiologies were associated with higher mortality. CONCLUSION: The growing incidence of NAFLD-HCC documented in the United States and Europe is also observed in Argentina, a confirmation with important Public Health implications.
