Multidisciplinary strategies to improve treatment outcomes in hepatocellular carcinoma

2013

Hepatocellular carcinoma (HCC) is a complex disease with a poor prognosis. Incidence and mortality rates are increasing in many geographical regions, indicating a need for better management strategies. Among several risk factors for HCC, the most common are cirrhosis because of chronic hepatitis B virus or hepatitis C virus infection and alcohol consumption, obesity, and diabetes. In some patients, combined risk factors present additional challenges to the prevention and treatment of HCC. Screening and surveillance of high-risk populations varies widely by geographic regions, and access to optimal surveillance is critical for early diagnosis. The treatment choice for HCC depends on the canc…

Role of the GALAD and BALAD-2 Serologic Models in Diagnosis of Hepatocellular Carcinoma and Prediction of Survival in Patients.

2016

Background & Aims GALAD and BALAD-2 are statistical models for estimating the likelihood of the presence of hepatocellular carcinoma (HCC) in individual patients with chronic liver disease and the survival of patients with HCC, respectively. Both models use objective measures, particularly the serum markers α-fetoprotein (AFP), AFP-L3, and des-γ-carboxyprothrombin. We aimed to validate these models in an international cohort of patients with HCC and assess their clinical performance. Methods We collected data on cancer diagnosis and outcomes of 6834 patients (2430 with HCC and 4404 with chronic liver disease) recruited from Germany, Japan, and Hong Kong. We also collected data from 229 pati…

Outcomes of hepatocellular carcinoma patients treated with sorafenib: a meta-analysis of Phase III trials

2019

Aim: To benchmark overall survival (OS) and time to radiological progression (TTP) of patients enrolled in randomized controlled trials (RCTs) assessing sorafenib in advanced hepatocellular carcinoma using individual participant survival data, and to meta-analyze prognostic factors for OS and TTP. Methods: RCTs were identified through literature search until December 2018. Individual participant survival was reconstructed with an algorithm from published Kaplan–Meier curves. Results: Ten RCTs were included. Median OS was 10.0 months (95% CI: 9.6–10.5), and median TTP was 4.1 months (95% CI: 3.8–4.3). Multivariable analyses showed HCV positivity, absence of macrovascular invasion and extra-…

The GALAD Score as Potential Screening Test for Hepatocellular Carcinoma in Nonalcoholic Steatohepatitis: An International Multicenter Study

2019

The prevalence of nonalcoholic steatohepatitis (NASH) is rising rapidly and is currently the most common chronic liver disease in Western populations. Hepatocellular carcinoma (HCC) is a major complication of NASH and the current performance of screening approaches based on ultrasound shows limitations. To facilitate earlier diagnosis, this international multicenter study, with eight German and one Japanese center participating, tests the potential benefit of applying the biomarkers AFP, AFP-L3, DCP and related scores for HCC screening in NASH patients. In the retrospective German cohort, 126 NASH patients with newly diagnosed HCC and 231 NASH control patients without HCC were enrolled. In …

Risk estimation for biliary tract cancer: Development and validation of a prognostic score.

2017

Background & Aims Biliary tract cancer is a rare tumour entity characterized by a poor prognosis. We aimed to identify prognostic factors and create a prognostic score to estimate survival. Methods Clinical data of the training set, consisting of 569 patients treated from 2000 to 2010 at Hannover Medical School, were analysed. A prognostic model defining three prognostic risk groups was derived from Cox regression analyses. The score was applied and validated in an independent cohort of 557 patients from four different German centres. Results Median overall survival (OS) was 14.5 months. If complete resection was performed, the patients had a significantly improved OS (23.9 months; n=242) a…

GALAD Score Detects Early Hepatocellular Carcinoma in an International Cohort of Patients With Nonalcoholic Steatohepatitis

2020

Background & Aims The prevalence of nonalcoholic steatohepatitis (NASH) associated hepatocellular carcinoma (HCC) is increasing. However, strategies for detection of early-stage HCC in patients with NASH have limitations. We assessed the ability of the GALAD score, which determines risk of HCC based on patient sex; age; and serum levels of α-fetoprotein (AFP), AFP isoform L3 (AFP-L3), and des-gamma-carboxy prothrombin (DCP), to detect HCC in patients with NASH. Methods We performed a case-control study of 125 patients with HCC (20% within Milan Criteria) and 231 patients without HCC (NASH controls) from 8 centers in Germany. We compared the performance of serum AFP, AFP-L3, or DCP vs GALAD …
