Statistical cure from intrahepatic cholangiocarcinoma (ICC) by hepatic resection was approximately 10% and varied by several tumor-specific factors, according to an online article published ahead of print in the journal Cancer.
A total of 584 patients who underwent surgery with curative intent for ICC between 1990 and 2013 at one of 12 participating institutions were identified. A nonmixture cure model was adopted to compare mortality after hepatic resection with the mortality expected for the general population matched by sex and age.
Findings showed that median 1-year, 3-year, and 5-year disease-free survival was 10 months, 44%, 18%, and 11%, respectively.

The overall survival was 27 months, 75%, 37%, and 22%, respectively. The mortality of patients undergoing surgery for ICC was higher than that of the general population until year 10.

Cure probabilities, as measured by multivariate analyses, demonstrated that probabilities ranged from 25.8% (time to cure, 9.8 years) in patients with a single, well-differentiated ICC measuring ≤5 cm that was without vascular/periductal invasion and lymph node metastases versus <0.1% (time to cure, 12.6 years) among patients with six risk factors. Researchers developed a model with which to calculate cure fraction and time to cure was developed.
