Item Pre-treatment alphafeto protein in hepatocellular carcinoma with non-viral aetiology - a prospective study(BioMed Central, 2017) Siriwardana, R.C.; Thilakarathne, S.; Niriella, M.A.; Dassanayake, A.S.; Gunetilleke, M.B.; Habarakada, L.C.A.; de Silva, H.J.BACKGROUND: Alpha-fetoprotein (AFP) is a biomarker for hepatocellular carcinoma (HCC). The significance of pre-treatment AFP (pt-AFP) in non-viral HCC (nvHCC) is not clear. METHODS: Patients with nvHCC, referred to a Hepatobiliary Clinic from September 2011-2015 were screened. HCC was diagnosed using American Association for the Study of Liver Disease guidelines, and TNM staged. nvHCC was diagnosed when HBsAg and anti-HCVAb was negative. Child-Turcotte-Pugh (CTP) and Model for End-stage Liver Disease (MELD) scores were calculated. AFP level was evaluated against patient characteristics, tumour characteristics and survival. RESULTS: Three hundred eighty-nine patients with nvHCC [age 64(12-88) years; 344(88.4%) males] were screened. Median AFP was 25.46 ng/ml (1.16-100,000). 41.2% (n = 160) Of patients had normal AFP level. 22.9% (n = 89) had AFP over 400 ng/ml. Female gender (P < 0.05), vascular invasion (P < 0.001), tumours over 5 cm (P < 0.05), late TNM stage (P < 0.001) and non-surgical candidates had higher AFP levels. Diffuse type (P < 0.001), macro vascular invasion (P < 0.001) and late stage tumours (P < 0.001) had AFP over 400 ng/ml. Having AFP below 400 ng/ml was associated with longer survival (16 vs. 7 months, P < 0.001). CONCLUSION: Pre treatment AFP has a limited value In diagnosing nvHCC, Having a AFP value over 400 ng/ml was associated with aggressive tumour behaviour and poor prognosis.Item Clinical characteristics and outcome of hepatocellular carcinoma in alcohol related and cryptogenic cirrhosis:a prospective study(Elsevier, 2015) Siriwardana, R.C.; Niriella, M.A.; Dassanayake, A.S.; Liyanage, C.; Gunetilleke, B.; Jayathunge, S.; de Silva, H.J.BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is becoming a leading cause of chronic liver disease. Hepatocellular carcinoma (HCC) is one of its complications. Although the pathophysiology is unclear, it is reasonable to expect that cryptogenic cirrhosis related HCC (cryptogenic HCC) behaves differently to other types of HCC. This study prospectively compared patients with cryptogenic HCC and those with HCC related to alcoholic cirrhosis. METHODS: A total of 150 consecutive patients with HCC (89 cryptogenic HCC and 61 alcohol related HCC) referred to our unit over a 23-month period were studied. Their demographic data, liver function, tumor characteristics and outcomes were compared. RESULTS: Alcohol related HCC was seen only in males. Compared with cryptogenic HCC, alcohol related HCC had significantly higher aspartate aminotransferase/alanine aminotransferase (AST/ALT) ratio (1.7 vs 1.4, P=0.002), model for end-stage liver disease score (13 vs 11, P=0.018) and Child's score (7 vs 6, P=0.037). No significant difference was seen in platelet counts, serum sodium and AST to platelet ratio index. Single nodular tumors were more common in cryptogenic HCC, while diffuse type tumors and macroscopic vascular invasion were common in alcohol related HCC. In patients who could not be offered any treatment because of advanced tumors or poor liver function, alcohol related HCC had a significantly lower median survival (5.3 months) compared with cryptogenic HCC (9.3 months, P=0.034). CONCLUSIONS: Compared with cryptogenic HCC, alcohol related HCC had worse liver function and aggressive tumor morphology at presentation, and a higher proportion was untreatable. In patients who could not be treated, median survival was lower in patients with alcohol related HCC than in those with cryptogenic HCC.
