Summary
Background:
Colorectal cancer (CRC) remains a major health burden with an incidence of 1.3 million new cases worldwide and a mortality of almost 8.5%. It is the 2nd most common cancer in women (1st breast carcinoma) and 3rd most common in men (1st lung carcinoma, 2nd prostate carcinoma). CRC alongside breast, lung, prostate and stomach cancer is in the top five most common cancers in men and women worldwide. There are still more than 50% of CRC patients diagnosed with advanced disease (stage III and IV) in the Czech Republic. Genetically, CRC is a very heterogeneous disease with many factors playing key roles in pathogenesis. There are two types of CRC, hereditary with an incidence of between 5% and 10% with APC (FAP, aFAP) or MMR (HNPCC) genes affected, and sporadic colorectal cancer with an incidence of 90–95% with a lot of mutations in variable genes that accumulate during pathogenesis (APC, KRAS, MMR, microRNA, CIMP etc.). Knowledge of the molecular pathogenesis of CRC (hereditary, sporadic) is crucial for treatment, assessment of risk, prognosis, and patient follow-up.
Conclusion:
This article summarizes the molecular pathogenesis of sporadic and hereditary CRC.
Keywords:
colorectal cancer – pathogenesis – hereditary – sporadic – risk factors
