RESUMO
BACKGROUND: Anaemia is frequent in patients with cancer and/or liver cirrhosis and is associated with impaired quality of life. Here, we investigated the impact of anaemia on overall survival (OS) and clinical characteristics in patients with hepatocellular carcinoma (HCC). MATERIALS AND METHODS: HCC patients treated between 1992 and 2018 at the Medical University of Vienna were retrospectively analysed. Anaemia was defined as haemoglobin level <13 g/dl in men and <12 g/dl in women. RESULTS: Of 1262 assessable patients, 555 (44.0%) had anaemia. The main aetiologies of HCC were alcohol-related liver disease (n = 502; 39.8%) and chronic hepatitis C (n = 375; 29.7%). Anaemia was significantly associated with impaired liver function, portal hypertension, more advanced Barcelona Clinic Liver Cancer stage and elevated C-reactive protein (CRP). In univariable analysis, anaemia was significantly associated with shorter median OS [9.5 months, 95% confidence interval (95% CI) 7.3-11.6 months] versus patients without anaemia (21.5 months, 95% CI 18.3-24.7 months) (P < 0.001). In multivariable analysis adjusted for age, Model for End-stage Liver Disease, number of tumour nodules, size of the largest nodule, macrovascular invasion, extrahepatic spread, first treatment line, alpha-fetoprotein and CRP, anaemia remained an independent predictor of mortality (adjusted hazard ratio 1.23, 95% CI 1.06-1.43, P = 0.006). CONCLUSIONS: Anaemia was significantly associated with mortality in HCC patients, independent of established liver- and tumour-related prognostic factors. Whether adequate management of anaemia can improve outcome of HCC patients needs further evaluation.
RESUMO
BACKGROUND: There is no clear consensus on the optimal systemic treatment regimen in combined hepatocellular-cholangiocarcinoma (cHCC-CCA) patients. We describe clinical characteristics and outcome of cHCC-CCA patients, with a special focus on patients receiving palliative systemic therapy, including immune checkpoint inhibitors (ICIs). METHODS: In this European retrospective, multicenter study, patients with histologically proven cHCC-CCA treated at four institutions between April 2003 and June 2022 were included. In patients receiving palliative systemic therapy, outcome was compared between cytotoxic chemotherapy (CHT)- and non-cytotoxic CHT (nCHT)-treated patients. RESULTS: Of 101 patients, the majority were male (n = 70, 69%) with a mean age of 64.6 ± 10.6 years. Only type of first-line treatment was independently associated with overall survival (OS). Palliative systemic therapy was administered to 44 (44%) patients. Of those, 25 (57%) patients received CHT and 19 (43%) had nCHT (n = 16 of them sorafenib) in systemic first line. Although there was no significant difference in overall response rate (ORR; CHT versus nCHT: 8% versus 5%), disease control rate (24% versus 21%), and median progression-free survival {3.0 months [95% confidence interval (CI) 1.4-4.6 months] versus 3.2 months (95% CI 2.8-3.6 months), P = 0.725}, there was a trend towards longer median OS in the CHT group [15.5 months (95% CI 8.0-23.0 months) versus 5.3 months (95% CI 0-12.5 months), P = 0.052]. However, in multivariable analysis, type of first-line regimen (CHT versus sorafenib) was not associated with OS. ORR in patients receiving ICIs (n = 7) was 29%. CONCLUSIONS: In patients with cHCC-CCA, OS, progression-free survival, ORR, and disease control rate were not significantly different between individuals receiving CHT and patients receiving nCHT. Immunotherapy may be effective in a subset of patients. Prospective studies are needed to identify optimal systemic treatment regimens in cHCC-CCA.
