The specific etiologic factors and pathogenetic mechanisms, underlying the development of cancers of the colon and rectum appear to be complex and
heterogeneous
. Despite the continuous advancement in diagnostic and therapeutic methods, despite the global and national programs for prevention it is evidenced increase in
colorectal cancer
(CRC) incidence and mortality.Further progress is needed in the field of non-invasive diagnostic methods to enable early diagnosis, pre and postoperative staging, and to assist in selecting the most suitable neo-adjuvant and adjuvant therapeutic methods and post-treatment follow-up. There are attempts to "personalise and individualise" anticancer therapy based on presence or absence of specific biomarkers. In this review we will focus on the prevalence, the latest progress made within the genomic and proteomic fields and their significance as possible prognostic and predictive markers in CRC patients.
