VELAZQUEZ, Sebastián Aníbal et al. Risk of recurrence and risk factors for invasion of differentiated thyroid cancer. An. Fac. Cienc. Méd. (Asunción) [online]. 2022, vol.55, n.2, pp.32-39. ISSN 1816-8949. https://doi.org/10.18004/anales/2022.055.02.32.
Introduction:
Differentiated thyroid cancer (DTC) is represented by papillary carcinoma and follicular carcinoma. It comprises the vast majority (> 90%) of all thyroid cancers.
Objectives:
Stratify the risk of initial recurrence of patients with DTC. Relate age, sex, and tumor size to the risk of recurrence, capsular, nodal, vascular, and perithyroid tissue invasion.
Materials and methods:
Observational, descriptive, retrospective, cross-sectional study with an analytical component. A total of 432 patients with a diagnosis of DTC from Hospital de Clínicas, Instituto de Previsión Social and Instituto Nacional del Cáncer between 2011 and 2015 were included.
Results:
87% were female. The mean age was 43 ± 14 years. Low recurrence risk predominated in 49% of patients, followed by intermediate risk (33%) and high risk (18%). Male sex, age ≥55 years and tumor size ˃1cm confer a higher risk of being stratified as intermediate / high recurrence risk, but only size> 1cm was significantly (OR 5.7 95% CI 3.6-9). Male sex represented a higher risk of lymph node invasion (OR 3.1 95% CI 1.4-2.8) and vascular invasion (OR 2.3 95% CI 1.1-4.8); age ≥55 years was in the vascular invasion (OR 2.6 95% CI 1.4-4.9); size> 1cm constituted a significantly higher risk of capsular invasion (OR 10.7 95% CI 6.7-17.3), nodal invasion (OR 10.5 95% CI 4-27.7), vascular invasion (OR 33 95% CI 4.5-244) and invasion of perithyroid tissue (OR 5.1 95% CI 3.2-8.1).
Conclusion:
The most frequent initial recurrence risk was low risk. Male sex, age ≥55 years, and size> 1cm are risk factors for invasion of neighboring structures.
