Item Characteristics and survival of advanced untreated hepatocellular carcinoma of non-viral etiology(Indian Society of Gastroenterology, 2024) Ekanayaka, S.P.N.; Luke, N.; Thilakarathne, S.B.; Dassanayake, A.; Gunetilleke, M.B.; Niriella, M.A.; Siriwardana, R.C.INTRODUCTION AND OBJECTIVES Hepatocellular carcinoma (HCC) is an aggressive tumor and presents late. The underlying etiology of HCC is changing rapidly. HCC in Sri Lanka is unique due to its predominant non-viral etiology (nvHCC) but lacks survival data.METHOD Data was collected from patients who presented with HCC from 2011 to 2018. There were 560/568 (98.6%) nvHCC. The patients who were not candidates for tumor-specific treatment (149/560 [26.7%]) were selected. Population characteristics, demographic data, tumor characteristics, survival and factors affecting survival were analyzed.RESULTS The median age was 64 years (range 30-88) and 86% (n = 129) were males. As many as 124 (83%) were cirrhotic. The overall performance score was 80%. Nearly 21/124 tumors were detected in cirrhotic screening. Tumors were single nodular in 32 (21%), up to three nodules in 28 (18%), more than three nodules in 33 (22%) and diffusely infiltrating in 56 (37%). The major venous invasions were present in 78 (52.3%). Extra-hepatic tumor spread was seen in 19 (12.7%) (lungs 13 [72.2%], bones 2 [11.1%]). The median survival of patients receiving palliative care was three months (1-43 months). Tumor size and cirrhotic status were significant predictors in univariate analysis.CONCLUSION A quarter of nvHCCs were not amenable to treatment at presentation as they had dismal survival.Item Clinical characteristics and outcomes of hepatocellular carcinoma: results from prospective study, from a tertiary referral center in Sri Lanka(Sri Lanka Medical Association, 2018) Bulathsinhala, B.K.S.; Siriwardana, R.C.; Gunetilleke, M.B.; Niriella, M.A.; Dassanayake, A.S.INTRODUCTION:Hepatocellular carcinoma is increasing globally. Compared to global patterns, hepatitis B and C are rare in Sri Lanka whilst non-alcoholic fatty liver disease (NAFLD) and alcohol are the commonest causes of hepatocellular carcinoma.OBJECTIVE:To determine the characteristics of a cohort of Sri Lankan patients with hepatocellular carcinoma of non-viral aetiology.METHODS:Details of 550 consecutive patients with hepatocellular carcinoma referred from 2012 to 2017 were collected prospectively. Demographic data, clinical and biochemical details, aetiology, comorbidities, tumor characteristics and type of treatment offered were retrospectively analyzed.RESULTS:Median age was 62.9 years (range 12 - 88) with male preponderance (n = 473; 86%). Overall median BMI was 35.8 kgm-2. Majority (n=309; 56 %) had NAFLD induced cirrhosis, second commonest cause was alcohol (n=203;36.9 %). Tumour was single nodular 233(42.4%) and diffusely infiltrating 92(16.7%). Diagnostic rise in serum alpha-fetoprotein (over 200 micrograms) was seen in 30.2%. Venous invasion was present in 28.5% [portal vein 136 (24.7%), hepatic vein 9 (1.6%) and cava 12(2.2%)]. Extra hepatic tumor spread was seen in 6.9% [lungs 20(3.6%), bones 4(0.7%), peritoneal 6 (1.1%) and metastases at other sites 8 (1.45%)]. Curative surgery was offered in 78(14.2%). Tumour embolization was done in 192(34.9%), radio frequency ablation 34(6.2%), alcohol injection 42(7.6%) and 204(37.1%) patients were offered palliative care. Overall median survival was 20.6 months.CONCLUSION:In a large Sri Lankan cohort, most hepatocellular carcinomas were due to cryptogenic cirrhosis and it was aggressive at presentation. Screening of high-risk NAFLD patients needs to be considered and further palliative care needs to be improved.
