Remarkable improvements in the understanding of the development of human cancer and of its genetic nature have been reported. At our services, we have observed that there is a high incidence of gastrointestinal tumors in our region and, also, that poor prognosis occurs due to patients presenting with advanced stages of the disease. In this sense, it is expected that molecular biology studies will bring new hope for more effective diagnostic and treatment methods. Consequently, it is our objective to address the current aspects on colorectal, gastric, and esophageal carcinogenesis and the genes and products involved. The application of recent findings, used for early diagnosis, the existence of markers for prognosis, and the possibility of using new methods of treatment are discussed.
