26 #CRC_Clinical_Risk_Factors Certain Medical Conditions Smoking,Alcohol Diabetes Obesity Lack of exercise Diet Age Genetic
27 Revised Amsterdam criteria There should be at least three relatives with an HNPCCassociated cancer (colorectal cancer, cancer of the endometrium, small bowel, ureter, or renal pelvis) One should be a first degree relative of the other two At least two successive generations should be affected At least one should be diagnosed before age 50 Familial adenomatous polyposis should be excluded in the colorectal cancer case(s) if any Tumors should be verified by pathological examination
28 Biomarkers Scores Genetic Scores Molecular Scores Serological Scores
29 CRC - Risk Stratification Module Genetic Scores Genetic testing for hereditary CRC : APC gene mutations MMR gene mutations (MLH1, MSH2, MSH6, PMS2) Genetic testing for targeted cancer therapy of CRC : KRAS, BRAF, PIK3CA mutations Genetic testing for individualized chemotherapy of CRC: AKT1, UGT1A1, DPYD, MTHFR, ERCC1, XRCC1 and GSTP1 gene polymorphism
30 #CRC_Tumorigenesis Molecular pathways The chromosomal instability (APC) pathway The mutator phenotype/mismatch repair (MMR)pathway Hypermethylation phenotype (CIMP+) pathway
31 Genetic Biomarkers for Detection
32 Genetic Biomarkers for Detection a Numbers in parentheses represent prevalence of genetic mutations reported *. b Specimens listed are those in which the assay for mutations can be performed *Chung C. C. The genetic basis of colorectal cancer: insights into critical pathways of tumorigenesis. Gastroenterology, 119: , 2000
33 Common methylated genes (and loci*) identified at the histologic steps of the CRC The genes may be involved in the initiation of CRC Those genes may play a role in the progression and metastasis of CRC Victoria Valinluck Lao et al,nat Rev Gastroenterol Hepatol. ; 8(12):
34 Genetic module #CRC tumorigenesis LOH: loss of heterozygosity; DCC: deleted in colon cancer gene; APC: adenomatous polyposis coli gene; ACF: aberrant crypt foci; MMR: DNA mismatch repair enzyme.
