Abstract
Background: Thyroid neoplasms exhibit a diverse evolutionary trajectory, suggesting distinct pathways from normal thyroid cells to malignancy.
Methods: Molecular changes initiating follicular adenoma formation likely precede progression to follicular cancer. Papillary carcinoma, however, may evolve via a separate pathway, bypassing follicular adenoma. Subsequent genetic alterations can lead to anaplastic cancer, significantly impacting prognosis.
Results: Genome instability predisposes thyroid tumour cells to molecular alterations, with proto-oncogene changes occurring early and suppressor gene mutations typically occurring later. These changes contribute to aggressive or invasive behaviours, potentially influencing clinical outcomes.
Conclusion: Advances in understanding genetic alterations in thyroid oncogenesis offer promise for enhancing diagnostic accuracy and treatment efficacy, thereby improving outcomes for thyroid malignancies.
