mirSNPs as Potential Colorectal Cancer Biomarkers: A Systematic Review
Thyroid, cancer, biomarkers, SNPs.
Thyroid cancer (TC) is the most common endocrine malignancy, with an increasing incidence
worldwide. The investigation of genetic biomarkers has shown promise in understanding disease
susceptibility and clinical behavior. This study aimed to analyze the association of single nucleotide
polymorphisms (SNPs) with the risk and prognosis of TC in a genetically admixed Brazilian
population.
Twelve SNPs were evaluated in a retrospective cohort comprising patients with TC, individuals
with benign thyroid diseases (BTD), and healthy controls. Genotyping was performed using
standardized molecular methods, and data were analyzed through logistic regression adjusted for
age and sex, considering different inheritance models.
Four polymorphisms showed statistically significant associations. SNPs rs10759944 and rs7850258
were consistently associated with an increased risk of developing TC. In contrast, rs1571443 was
associated with a protective effect against the disease. Additionally, rs949908 was linked to a lower
cancer risk among heterozygotes and with earlier tumor staging, suggesting a possible protective
role in prognosis.
These findings indicate that specific genetic variants may influence both susceptibility and clinical
progression of thyroid cancer. They also contribute to the understanding of genetic protection
mechanisms, supporting early diagnostic strategies and future applications in personalized
medicine.
