Abstract

AIM: To review the experience with hilar cholangiocarcinoma and to determine the results of a radical surgical approach in a UK centre.

METHODS: A 10-year review of all patients treated surgically for proximal bile duct carcinoma at a single surgical unit was conducted. Patient demographics, disease details and histopathology reports were reviewed. From January 1993 through December 2003, 106 patients were admitted with the diagnosis of hilar cholangiocarcinoma and 61 patients received surgical exploration.

RESULTS: Tumours were staged as follows (UICC 6th edition): stage IB, n=10 IIA, n=9; IIB, n=20; III, n=8; IV, n=14. Out of 61 patients, 44 had a resection (3 bile duct resection alone, 41 liver resection with bile duct resection), 5 were considered unresectable and 12 underwent liver transplantation (LT). The caudate lobe was excised in 34 of the patients and regional lymphadenectomy was systematically carried out. Para-aortic lymphadenectomy was performed in 17 cases. Portal vein resection was needed in 17 and hepatic artery resection was performed in 4 cases. Negative histologic margins (R0) were achieved in 20 patients and microscopic margin involvement (R1) was seen in 16. In the remaining 8 resected patients, localised metastasis were found (peritoneal deposits in 2, liver metastasis in 4 and positive para-aortic lymph nodes in 2); nevertheless the resection was performed and it was considered R2. Overall survival at 3 and 5 years for patients who underwent a resection was 43% and 28% including postoperative deaths. The 1-, 3- and 5-year actuarial survival rates for patients who underwent R0 resection were 78%, 64% and 45% respectively, including the postoperative deaths (n=3). The median survival time was 41.1 months. The 1-, 3- and 5-year actuarial survival rates for R1 resection and R2 were 60%, 26%, 26% and 25% and 0% respectively, while the median survival time for these groups was 15.4 and 6.8 months respectively. The actuarial survival rate at 1, 3 and 5 years for well-differentiated tumours (G1) was 73%, 54% and 40% (median 39.7 months). The figures for G2 were 60%, 48% and 0%. The figures for G3 (poorly differentiated) were 16% and 0% at three years (p=0.03).The overall survival at 3 and 5 years for those patients who had a liver transplant was 41% and 20% including early postoperative mortality. The tumour grading (presence of poorly differentiated tumour) was found to be the only independent factor affecting the survival time producing a hazard ratio of 4.3 (p=0.0034, 95% confidence interval 0.1007-6.342).

CONCLUSIONS: Radical surgical resection is the best treatment for hilar cholangiocarcinoma. R0 resection provides acceptable 5-year survival, but R1 resection may also provide acceptable palliation. In our experience TNM stage and tumour grade were the main determinants of long-term survival.
