[Clasificación molecular del carcinoma de colon y recto. Una revisión corta].

Traditionally, carcinoma classifications have been based on clinical or pathological features. However, with the development of molecular biology in recent decades, more tumors are increasingly being genetically studied and, in several of them, molecular classifications have been created (the most widely studied and used is that for breast cancer). Colon and rectum cancer are no exception. In this short review, the evolution of colon and rectum cancer molecular classification is explained and the consensus conclusions on the subject are addressed.
