Survival analysis of 230 patients with unresectable hepatocellular carcinoma treated with bland transarterial embolization.

ABSTRACT: Locoregional therapies for hepatocellular carcinoma (HCC) include endovascular treatments such as chemoembolization (TACE) and bland embolization (TAE). TACE is the most adopted technique, despite a lack of definitive evidence of superiority over TAE, which is less costly and better tolerated due to the absence of chemotherapy. However, few studies have reported data on TAE monotherapy for unresectable HCC. We report our results in a cohort of 230 patients with unresectable HCC treated with TAE (TAE with 40-100micron microparticles, TAE with microparticles plus n-butyl-2-cyanoacrylate, TAE with Lipiodol) over the course of seven years. Thirty-seven patients (14%) were down-staged during observation and also received a percutaneous ablation. We observed 1-, 2-, 3-, 4- and 5-year rates of 84,8%, 58,7%, 38,3%, 28,3%, and 18,7%. Patients who also received percutaneous treatment performed best. Our results broaden the body of evidence for the use of TAE in advanced HCC.

Project description:Sarcopenia has been associated with lower overall survival in patients with cirrhosis and hepatocellular carcinoma (HCC) undergoing surgical resection, TACE, TARE, or transplantation. This monocentric study evaluated the prognostic significance of sarcopenia in patients affected by HCC who received bland transarterial embolization (TAE) therapy, by analyzing its impact on survival and treatment-related complications. All consecutive patients who underwent the 1st TAE between March 1st 2011 and July 1st 2019 in our Institution were retrospectively studied. To evaluate sarcopenia, the skeletal muscle index (SMI) was calculated by normalizing the cross-sectional muscle area at the level of L3 on an abdominal CT scan prior to embolization (cm2) by patient height (m2). SMI cut-off values for sarcopenia were considered ≤ 39 cm2/m2 for women and ≤55 cm2/m2 for men. Data about age, gender, body mass index (BMI), underlying liver disease, liver function, MELD score, Child-Pugh score, multifocal disease, performance status, previous interventions, length of stay (LOS), complications after the procedure, readmission rate within 30 days, survival time from TAE and total number and type of TAE received following the first procedure were collected. From 2011 to 2019, 142 consecutive patients underwent 305 TAEs. Observation time ranged from 1.4 to 100.5 months (median 20.1 SD = 22). Sarcopenia at baseline was present in 121 (85%) patients. Overall 87 (61.2%) patients died during follow-up with survival rates at 1-, 2-, 3-, 4-, and 5-year of 71%, 41%, 22%, 16% and 11% respectively. After multivariate analysis sarcopenia (HR = 2.22, p = 0.046), previous ablation/resection (HR = 0.51, p = 0.005) and multifocal disease (HR = 1.84, p = 0.02) were associated with reduced survival. Sarcopenia did not influence the safety of TAE in terms of LOS (2 days vs 1.5 days, p = 0.2), early complications rate (8% vs 5%, p = 0.5) and readmission rate within 30 days (7% vs 5%, p = 0.74). Sarcopenia, estimated by the L3SMI method, is an emerging prognostic factor in patients with HCC undergoing bland TAE therapy as it is associated with increased mortality, without impairing the safety of the locoregional treatment. Measures to ameliorate the SMI, such as nutritional support and physical exercise, should be evaluated in clinical trials for HCC patients receiving liver embolization to determine their impact on overall survival.
