(Sri lanka Medical Association, 2015) Wickramarathne, S.D.J.; Jayarathne, V.S.; Siriwardana, R.C.; Liyanage, C.A.H.; Niriella, M.A.; Dassanayake, A.S.; Gunetilleke, M.B.; de Silva, A.P.; de Silva, H.J.
INTRODUCTION AND OBJECTIVES: Incidence of hepatocellular carcinoma (HCC) is increasing. Diffuse HCC (dHCC) is rare and data on such tumours are limited. METHOD: Ail consenting patients with HCC referred to Colombo North Liver Unit, Ragama (September 2011-February 2014) were Included. Tumours with diffuse margins on imaging were categorized as dHCC, while tumours with clear nodular morphology were categorized as nodular HCC (nHCC). Baseline parameters, treatment options and survival were compared between the two types. RESULTS: 203 HCCs were included in the study [dHCC=41(20%):87.8% males; nHCC=162(80%) 89.5% males]. The median age at presentation in the two groups was similar [dHCC 63.58(47-76) years, nHCC 62.13(12-88) years]. More patients with dHCC had a significant alcohol intake (68.9% vs. 41.7%, p=0.002). Background cirrhosis was present in 90.2% of dHCC compared to 79.1% in nHCC (p<0.05). Aspartate transaminase, Alanine transaminase, INR, total bilirubin, platelet count and MELD scores were similar in the two groups. Median alfa fetoprotein (AFP) was significantly higher in dHCC (136 vs 31ng/mL, p<0.001). Similar typical enhancement pattern on dynamic imaging was noted in the two groups (80.5% dHCC, 84.4% nHCC). dHCC had high incidence of major vascular invasion(78% vs 23.5%, p<0.001). Seventy six point nine percent of dHCC had only palliative care compared to 28.4% in nHCC was two months compared to 8 months in nHCC. CONCLUSION: 1/5 of HCCs were of the diffuse type. Patients dHCC had a significant alcohol intake. They had higher AFP, advanced disease at presentation with more vascular invasion and a worse prognosis than nHCC.
Diffuse and nodular type hepatoma: a prospective, comparative study
(Sri Lanka Medical Association, 2014) Wickramarathne, S.D.J.; Jayarathne, V.S.; Siriwardana, R.C.; Niriella, M.A.; Liyanage, C.A.H.; Dassanayake, A.S.; Gunetilleke, M.B.; de Silva, H.J.
INTRODUCTIONS: Incidence of hepatocellular carcinoma (HCC) is increasing. Diffuse type HCC is rare and data on such tumors are limited. METHODS: All patients referred to North Colombo Liver Unit with HCC from September 2011 to February 2014 were included. Data were collected prespectively from 206 patients. Tumors with diffuse margin in imaging were categorized as diffuse HCC (n-41, 21%). Baseline parameters, treatment options and survival were compared with nodulartype'HCC. RESULTS: 87.8% of patients in the diffuse HCC group were males compared to 89.54 % in nodular HCC group. The median age in the two groups were similar (nodular 62.13 years (range 12-88), diffuse 63.58 years (range 47-76)). Heavy alcohol use was commoner in the diffuse HCC group (68.9% vs. 41.7 %, p=0.002). 90.2% with diffuse HCC had cirrhosis compared to 79.1% with nodular HCC (p<0.05). Aspartate transaminase (AST), alanine transarninase (ALT), INR, total bilirubin, platelet count, MELD score were similar in two groups. Alfa Feto Protein (AFP) value was significantly higher in diffuse HCC group (p<0.001). 80.5% patients with diffuse type HCC had typical enhancement pattern compared to 84.4% with nodular type. Diffuse HCC group had higher incidence of major vascular invasion (78% vs. 23.5%, p<0.001). 76.9% of diffuse HCC group had only palliative care compared to 28.4% in nodular type (p<0.001). Median survival in diffuse group was 2.0 months compared to 8.0 months in nodular type. CONCLUSIONS: 21% of HCC are diffuse type. Alcohol intake was commoner in this group. Diffuse HCC had poorer prognosis with high AFP level and vascular invasion. Majority had advanced disease at presentation.
Hilar cholangiocarcionoma; Is aggressively answered
(College of Surgeons of Sri Lanka, 2015) Bandara, L.M.P.M.; Jayarathne, V.S.; Siriwardana, R.C.; Nawarathna, N.M.M.; Liyanage, C.A.H.
INTRODUCTION: Cholangiocarcinoma (CCA) is a malignant disease involving the billiary system with majority occurring in the hilar region. CCA demands prompt management because of its aggressive nature. MATERIALS AND METHODS: Patients who presented to Gastroenterology and hepatobiliary unit at NHSL and the Professorial Surgical Unit of NCTH from January 2011 to June 2015 were included in this study. Diagnosis was made by CT imaging, MRCP and ERCP. RESULTS: Total of 120 patients were diagnosed with CCA. The median age of presentation was 64 years (31-85) with 51.2% being males. Majority of 63 patients (52.1%) of CCA occurred in the hilar region with rest involving the common bile duct. Out of 63 hilar CCA 44 were classified according to the bismuth classification. 13/44 were type I, 7/44 were type II, 9/44 were of type III and 15/44 were of type IV. While 5 patients (7.9%) underwent hepatic resection, Majority of 40 patients (63.5 %) were stented with 9 (14.2%) being treated with Radiofrequency ablation (RFA). Survival was significant following surgery (P=0.027). Four patients who underwent surgery are currently followed up at NCTH. CONCLUSIONS: Surgery appears to be the effective treatment for CCA. Aggressive palliation with stenting seems beneficial.
Management of hilar cholangiocarcinoma

INTRODUCTION AND OBJECTIVES: Cholangiocarcinoma (CCA) is a malignant disease involving the biliary system with majority occurring in the hilar region. Cholangiocarcinoma demands prompt management because of its aggressive nature. METHODS: Patients who presented to North Colombo Teaching Hospital- Liver Unit (NCTH- LU) and National Hospital of Sri Lanka (NHSL- GHU) from January 2011 to March 2014 were included in this study. Diagnosis was made by CT imaging, magnetic resonance cholangiopancreatography (MRCP) and endoscopic retrograde cholangiopancreatography (ERCP). RESULTS: Total of 108 patients were diagnosed with CCA. The median age of presentation was 62 years (range 31-87). 51.4% were males. Majority (58.3%) of CCA occurred in the hilar region with rest involving the common bile duct. 76.8 % were stented and 8 patients were offered surgical treatment. Out of 62 hilar CCA 46 were classified according to the bismuth classification. 9 were type I, 8 were type II, 13 were type III and 16 were type IV. Six patients underwent hepatic resection, Majority (n=46) were stented, six were treated with radiofrequency ablation. Out of 45 patients with CBD involvement 33 were stented and 2 had Whipple's surgery. Six patients who underwent surgery are currently followed up at NCTH-LU. CONCLUSIONS: Surgery appears to be the effective treatment for cholangiocarcinoma. Aggressive palliation with stenting was beneficial.
