Development of a risk score to predict portal vein tumor thrombosis in patients with hepatocellular carcinoma.

BACKGROUND: Portal vein tumor thrombosis (PVTT) is a common complication of hepatocellular carcinoma and is one of the most negative prognostic factors. The management of patients with PVTT is challenging. The aim of the study was to develop a score predictive of tumor thrombosis. METHODS: Data from a large cohort of 2243 hepatocellular carcinoma patients (all stages) recorded in the Progetto Epatocarcinoma Campania (January 2013-April 2021) database were analyzed. To construct the score, univariate generalized estimated equation models, the bootstrap approach for internal validation, and a regression coefficient-based scoring system were used. RESULTS: PVTT (any location) was found in 14.4% of cases and was related to shorter survival. Males, younger patients, and symptomatic cases were more prevalent among the PVTT group. At multivariate analysis, size ≥5 cm, massive or infiltrative hepatocellular carcinoma growth, and alpha-fetoprotein ≥400 ng/mL were significantly associated with PVTT. A risk prediction score of PVTT based on eight variables was developed. Using a continuous score, the risk was associated with an odds ratio (OR) of 1.30 (1.27-1.34; P  < 0.001). Considering a dichotomous score >8 versus a score ≤8 the OR for PVTT was 11.33 (8.55-15.00; P  < 0.001). CONCLUSION: The risk score for PVTT might be useful for clinicians to optimize hepatocellular carcinoma management by picking out patients with more aggressive cancers and higher mortality rates. Prospective validation of the score is needed before its application in daily clinical practice.

Adherence to Barcelona Clinic Liver Cancer guidelines in field practice: Results of Progetto Epatocarcinoma Campania.

BACKGROUND AND AIM: The Barcelona Clinic Liver Cancer (BCLC) algorithm is the standard system for clinical management of hepatocellular carcinoma (HCC). Data on adherence to this therapeutic paradigm are scarce. This field practice study aimed to provide a description of HCC cirrhotic patients in Southern Italy, to evaluate the adherence to BCLC guidelines and its impact on patients' survival. METHODS: We analyzed the region-wide Italian database of Progetto Epatocarcinoma Campania, which includes data of HCC cirrhotic patients, prospectively collected from January 2013 to December 2015 in 16 regional centers. RESULTS: Overall, 1008 HCC patients were enrolled: 70.6% patients received therapies recommended by BCLC algorithm, while 29.4% underwent different treatments. Among patients who were treated in adherence to guidelines, a higher rate of diagnosis on surveillance programs, better liver function, lower rate of alpha-fetoprotein > 200 ng/mL, more early-stage and monofocal HCC, lower frequency of nodules > 5 cm, portal vein thrombosis and metastases were observed. The overall survival was evaluated according to HCC stage and no differences between groups and patients managed differently were found. The multivariate analysis showed that non-adherence to treatment guidelines was independently associated to the BCLC stage B, Child-Pugh classes B and C, and the presence of neoplastic thrombosis and metastases. CONCLUSION: Adherence to BCLC algorithm in field practice was high in early and end-stage HCC patients, but it was poor in intermediate and advanced patients.
