A simple online calculator may help clinicians predict the chance of very early recurrence after curative-intent resection for intrahepatic cholangiocarcinoma (ICC), according to a study.

US researchers used an international database to identify 880 patients (median age 59) who underwent ICC resection from 1990-2016.

Recurrence was within six months in 22%. Five-year overall survival was 9% in this group, significantly less than the 50% seen in patients without very early recurrence.

The team went on to develop two models to predict the odds of six-month, recurrence-free survival.
