ABSTRACT

Introduction: Currently there is agreement regarding the importance of categorizing patients by risk groups in order to choose the most accurate treatment for welldifferentiated thyroid cancer.
Objective: To describe the results of conservative surgery as well as of total thyroidectomy performed on patients with well-differentiated thyroid cancer.
Methods: A descriptive research of longitudinal cohort was performed between 1995 and 2016 at the General Surgery Service of Hermanos Ameijeiras Hospital. The main variables used were demographic, related with tumor, surgery type and type of results.
Results: 183 patients were studied. The most used surgery type was the total thyroidectomy (79.2%). Individuals aged 41-50 years were predominant (30.6%). Conservative technics were more frequently performed in the group of patients aged 19-40. For patients older than 40 years, the total thyroidectomy was the most frequent. The female sex was the biggest group (82.5%). The predominant tumor size was in the range from 1 to 2.9 cm. In the low-risk group, 30 conservative surgeries and 62 total thyroidectomies were performed. Conservative surgeries had no complications, relapse or mortality. Regarding total thyroidectomy, 3.3% of the patients suffered transitory dysphonia, 2.2% presented transitory hypoparathyroidism, and 0.5% presented permanent hypoparathyroidism. Local relapse after total thyroidectomy was suffered by 3.8% of patients and mortality was 2.2 %.
Conclusions: The conservative surgery had no complications, relapse or mortality, while total thyroidectomy did present them.
