In order to study the impact of FAP expression on CRC prognosis, we stratified its expression in primary conventional adenocarcinoma tissues with a range of clinical parameters tightly related to CRC aggressiveness such as histological grade, local invasion (pT), number of affected lymph nodes (N), presence/absence of metastasis (M) and the stage (TNM system). This evidence concerns the gene FAP and adenocarcinoma.
