Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Current standard treatments include surgical resection, radioactive iodine therapy, and thyroid hormone replacement. However, some patients develop radioiodine-refractory disease with an increased risk of recurrence and progression. Molecular alterations in the MAPK and PI3K pathways play critical roles in thyroid tumorigenesis, influencing therapeutic response and prognosis. Identifying novel biomarkers for early detection and risk stratification is crucial. Emerging evidence highlights the role of microRNAs (miRNAs) in thyroid cancer progression, functioning as oncogenes or tumor suppressors.
This retrospective case-control study aims to identify novel molecular markers linked to thyroid cancer aggressiveness. Archived formalin-fixed paraffin-embedded (FFPE) tissue and blood samples will be analyzed from patients with varying degrees of PTC and FTC invasiveness. Control samples will be histologically normal thyroid tissue from the same patients.
Next Generation Sequencing (NGS), including RNA-seq and miRNA-seq, will be employed to detect differentially expressed RNA molecules. Validation will be performed using Real-Time PCR in an independent cohort. High-throughput genomic sequencing (Illumina TruSight Oncology 500) will assess mutations, copy number variations, and tumor mutation burden to correlate genetic alterations with malignancy. Variants will be prioritized based on frequency differences in tumor vs. non-tumor populations and functional relevance.
The study will enroll patients with follicular cell-derived thyroid carcinoma. A power analysis indicates that 80 subjects provide \>80% statistical power for biomarker identification. Descriptive statistics, parametric/non-parametric tests, and machine learning approaches will analyze transcriptomic and genomic data. Receiver operating characteristic (ROC) curves will assess diagnostic biomarker accuracy, while logistic regression will model associations between molecular alterations and disease severity.
This study aims to uncover molecular mechanisms driving thyroid cancer progression and identify biomarkers for improved risk stratification, early diagnosis, and potential therapeutic targeting. Findings may enhance personalized treatment approaches in thyroid oncology.
