Personalized treatment of perihilar cholangiocarcinoma based on tumor genetic and molecular characteristics.

This editorial discusses the article written by Tchilikidi et al that was published in the latest edition of the World Journal of Gastrointestinal Surgery. Genetic and molecular profiling of perihilar cholangiocarcinoma (pCCA) has identified a number of key abnormalities that drive tumor growth and spread, including pyruvate kinase M2, proline rich 11, and transcription factor 7, etc. pCCA has specific genetic and molecular features that can be used to develop personalized treatment plans. Personalized treatment approaches offer new opportunities for effectively targeting the underlying drivers of tumor growth and progression. The findings based on tumor genetic and molecular characteristics highlight the importance of developing personalized treatment strategies.
