Introduction

Intrahepatic cholangiocarcinoma (ICC) are tumors that arise from either the second order branches of the intrahepatic bile duct or the more peripheral bile duct branches.

Methods

The cumulative and disease-free survival rates were calculated using the Kaplan–Meier method. The univariate correlation between the clinicopathological factors and survival were examined by the log-rank test. Factors independently associated with the survival were identified by the proportional hazard regression analysis. A P-value of less than 0.05 was considered to be statistically significant.

Intrahepatic cholangiocarcinoma: rising frequency, improved survival, and determinants of outcome after resection

Abstract
BACKGROUND: Despite data suggesting a rising worldwide incidence, intrahepatic cholangiocarcinoma (IHC) remains an uncommon disease. This study analyzes changes in IHC frequency, demographics, and treatment outcome in a consecutive and single institutional cohort. METHODS: Consecutive patients with confirmed IHC seen and treated over a 16-year period were included. The trend in IHC frequency over the study period was compared with that of hilar cholangiocarcinoma patients (HCCA) seen during the same time. Demographics and patient disposition, histopathologic, treatment, recurrence, and survival data were analyzed; changes in these variables over time were assessed.

Trends in Survival after Surgery for Cholangiocarcinoma: A 30-Year Population-Based SEER Database Analysis

Introduction
Data on long-term survival of patients after surgical resection are limited to single-institution case series. Reported 5-year survival rates in recent surgical series (irrespective of margin status) vary widely, from 17 to 40% for ICC6–14 and from 9 to 41% for ECC.
