چکیده
In carcinogenesis, KRAS is an essential oncogene that plays a key function. The polymorphism of rs61764370 is a candidate for cancer susceptibility in KRAS3' untranslated region. The current study aimed to determine the role and impact of the KRAS gene polymorphism (rs61764370 T>G) on the risk of ovarian cancer development in the Iraqi population. In total, 84 ovarian cancer patients and 28 ovarian benign tumors were involved in a case-control study. DNA extraction from the formalin-fixed/paraffin-embedded tissues, followed by the sequencing of PCR products was carried out in genetic analysis for the detection of the KRAS polymorphism (rs61764370 T>G). The results showed that the frequencies of the KRAS gene polymorphism (rs61764370) in ovarian cancer patients were 78 (92.85%) and 6 (7.15%) with genotypes homozygote TT and heterozygote TG, respectively. These corresponding values in patients with benign ovarian tumors were 25 (89.3%) and 3 (10.7%) with homozygote TT and heterozygote TG, respectively. None of the patients either with malignant or benign tumors have been detected with homozygote genotype GG. Genotype frequency of the TT and TG showed that the heterozygote TT genotype vs. TG and T allele vs. G allele were more frequent in malignant and benign tumors (P≤0.01). Statistically, there was no association between the KRAS polymorphism and the clinical characteristics of ovarian cancer patients, such as age, family history, menopause, histological type, tumor size, or tumor stage. In conclusion, a significant association was found between rs61764370 and the risk of ovarian cancer in the Iraqi population, particularly those with genotypes homozygote TT. On the other hand, genotypes had no relationship with any of the clinical characteristics of ovarian cancer patients. Additional well-designed studies with larger sample sizes are recommended to validate the precise role of KRAS LCS6 variations in ovarian cancer risk.
