Trends in liver cancer incidence between 1985 and 2009, Khon Kaen, Thailand: cholangiocarcinoma.

Abstract

The rate increase in the first 5 to 6 years may be due to improved completeness of the registry, since in the subsequent 10 to 12 years there is a rather stable rate. It may be, however, that the recent decline in incidence represents a real fall in risk.
