The Effect of Gene Mutations on Metastasis and Overall Survival in Metastatic and Nonmetastatic Colon Cancers

It is known that many genes are associated with colon cancer. We aimed to investigate the effect of gene mutations on metastasis and overall survival in metastatic and non metastatic colon cancers. A total of 50 patients with metastatic (n=25) and non metastatic (n=25) diagnosed with colon cancer between 2010 and 2018 were included in the study. APC, MUTYH, RAD50, MEN1, ATM, PALB2, NSH2, BRCA1, BRCA2, MLH1, BRIP1, TP53, PTEN, BARD1, MSH6, PMS2, NBN, and FAM175A gene mutations were evaluated using the next generation sequencing method. The effect of gene mutations on metastasis and overall survival were evaluated. The mean age of patients with colon cancer without distant metastasis was 48.64±14.72 years and for patients with distance metases was 56.68±11.65. The mean survival time of colon cancer patients with distant organ metastasis after the metastasis date was 104.36±58.59 weeks. The presence of APC, MUTYH, and TP53 genetic mutations was observed with a higher rate in metastatic colon cancer (p
