- There is no data at present concerning the KRAS mutation in patients from Martinique with colorectal cancer. Despite the fact that the incidence of this disease continues to increase there is no recent data to confirm it. This study has a descriptive purpose, allowing a comparison of the population from Martinique to other populations.
- A study of incidence of colorectal cancer, overseen by the Association from Martinique for the Epidemiological Search on Cancer (AMREC), also leads to a better knowledge of the local characteristics of the colorectal cancer.
- These two descriptive characteristics of colorectal cancer in Martinique will be useful data for the health professionals to provide their patients better care.
- The colorectal carcinogenesis is complex. It influences among others, the EGFR (Epidermal Growth Factor Receptor) which activation leads to tumoral proliferation, differentiation and invasion. The binding of the EGF (Epidermal Growth Factor) or of another ligand to the EGFR is responsible for the activation of the Ras- Raf and Pi3k pathways.
- The mutation of the genes KRAS, BRAF or PIK3CA results in their continuous activation, independently of the activation or of the pharmacological blocking of EGFR. The most frequently found mutation affects the KRAS gene (20 to 50 % of the cases). 90 % of these mutations are situated on codons 12 and 13 of this gene (70 % codon 12 and 30 % codon 13). These mutations are responsible for a decrease of the GTPase activity of the ras protein, which stays then in active conformation bound to the GTP. This leads to the blocking of the pathway and to the inactivity of the pharmacological blocking of EGFR.

Study of Pembrolizumab (MK-3475) vs Standard Therapy in Participants With Microsatellite Instability-High (MSI-H) or Mismatch Repair Deficient (dMMR) Stage IV Colorectal Carcinoma (MK-3475-177/KEYNOTE-177)
In this study, participants with MSI-H or dMMR advanced colorectal carcinoma will be randomly assigned to receive either pembrolizumab or the Investigator's choice of 1 of 6 standard of ca...
The aim of the investigators' randomized trial is to compare the short-term clinical outcome and survival between laparoscopic-assisted and open resection of colorectal carcinoma.

Clusters of colonic crypts that appear different from the surrounding mucosa when visualized after staining. They are of interest as putative precursors to colorectal adenomas and potential biomarkers for colorectal carcinoma.
Human COLORECTAL CARCINOMA cell line.
Tumors or cancer of the COLON or the RECTUM or both. Risk factors for colorectal cancer include chronic ULCERATIVE COLITIS; FAMILIAL POLYPOSIS COLI; exposure to ASBESTOS; and irradiation of the CERVIX UTERI.
Tumor suppressor genes located in the 5q21 region on the long arm of human chromosome 5. The mutation of these genes is associated with the formation of colorectal cancer (MCC stands for mutated in colorectal cancer).
