Moreover;there are no reliable indicators to determine the prognosis and response of CRC patients to therapy. By harnessing recent technological advances in molecular profiling techniques, it is anticipated that greater insight to the various combinations of genetic events or alternative pathways underlying carcinogenesis will be gained. By carrying out literature search, we were able to identify a comprehensive list of genes with high differential expression patterns in colorectal cancer that could serve as molecular markers to complement existing histopathological factors in diagnosis, follow up and therapeutic strategies for individualized care of patients.展开更多

From the analysis of the molecular genesis of colon cancer, four central tenets concerning the pathogenesis of cancer have been established. The first is that the genetic and epigenetic alterations that underlie colon cancer formation promote the cancer formation process because they provide a clonal growth advantage to the cells that acquire them. The second tenet is that cancer emerges via a multi-step progression at both the molecular and the morphologic level. The third is that loss of genomic stability is a key molecular step in cancer formation. The fourth is that hereditary cancer syndromes frequently correspond to germ line forms of key genetic defects whose somatic occurrences drive the emergence of sporadic colon cancers.展开更多
