Tumour Size over 3 Cm Predicts Poor Short-term Outcomes After Major Liver Resection for Hilar Cholangiocarcinoma. By the HC-AFC-2009 Group

Introduction: As mortality and morbidity after a curative resection remains high, it is essential to identify pre-operative factors associated with an early death after a major resection.

Methods: Between 1998 and 2008, we selected a population of 331 patients having undergone a major hepatectomy including segment I with a lymphadenectomy and a common bile duct resection for a proven hilar cholangiocarcinoma in 21 tertiary centres. The study's objective was to identify pre-operative predictors of early death (<12 months) after a resection.

Results: The study cohort consisted of 221 men and 110 women, with a median age of 61 years (range: 24-85). The post-operative mortality and morbidity rates were 8.2% and 61%, respectively. The 1-, 3- and 5-year overall survival rates were 85%, 64% and 53%, respectively. The median tumour size was 23 mm on pathology, ranging from 8 to 40. A tumour size >30 mm [odds ratio (OR) 2.471 (95% confidence interval (CI) 1.136-7.339), P = 0.001] and major post-operative complication [OR 3.369 (95% CI 1.038-10.938), P = 0.004] were independently associated with death <12 months in a multivariate analysis.

Conclusion: The present analysis of a series of 331 patients with hilar cholangiocarcinoma showed that tumour size >30 mm was independently associated with death <12 months.
