This study investigated the rs6983267 single nucleotide polymorphism (SNP) and its association with colorectal cancer (CRC) risk in Romanian individuals. While not a definitive predictor, findings suggest potential links warranting further investigation into CRC genetics.
Area of Science:
- Genetics and Molecular Biology
- Oncology
- Public Health
Background:
- Colorectal cancer (CRC) is a significant global health concern, particularly challenging to manage in elderly populations.
- Individualized treatment strategies are crucial for improving patient outcomes.
- Factors like comorbidities and disease stage influence hospitalization length and healthcare costs.
Purpose of the Study:
- To evaluate the association between the single nucleotide polymorphism (SNP) rs6983267 and the risk of developing colorectal cancer (CRC).
- To assess the impact of this specific genetic marker in a Romanian population.
- To explore potential correlations between genetic factors and clinical outcomes like length of hospitalization.
Main Methods:
- A case-control molecular genotyping study was conducted.
- DNA was extracted from peripheral venous blood of 32 CRC patients and 30 control individuals.
- Genotyping for the rs6983267 polymorphism was performed.
Main Results:
- The heterozygous genotype (G/T) for rs6983267 was found in 59.38% of CRC patients but in none of the control individuals.
- A higher percentage of CRC patients carried at least one G allele (81.21%) compared to controls (76.57%).
- An association was observed between length of hospitalization and factors influencing operating time.
Conclusions:
- The study suggests a potential, though not definitive, association between the rs6983267 SNP and CRC risk in the Romanian population.
- Further research is required to precisely determine the CRC risk associated with this SNP in this demographic.
- Clinical data indicated a link between hospitalization duration and surgical factors, independent of the studied SNP.
