Accuracy of the fine needle aspiration puncture in the diagnosis of differentiated thyroid cancer

Abstract

INTRODUCTION: The importance of thyroid nodules (NT) lies in the need to exclude thyroid cancer,
which occurs in 7 to 15% of cases. In Argentina it represents 2.2% and 0.5% of all cancers that occur
annually in women and men respectively. NT fine needle aspiration (PAAF) cytology estimates the risk of
malignancy and is the confirmatory test for diagnosis, with a specificity of 94%.
OBJECTIVE: To estimate de frequency of cardiovascular risk factors in a sample of patients with OSAS.
PATIENTS AND METHODS: We performed an observational, cross-sectional, descriptive study. We
included consecutive patients over 18 years of age diagnosed with OSA during the period between June 1,
2018 and December 30, 2018. The following variables were recorded: age, sex, body mass index (BMI),
arterial hypertensión (AHT), smoking, diabetes, dyslipidemia, clinical atherosclerotic cardiovascular
disease and 10-year cardiovascular risk assessment (CVR) calculated through the Cardiovascular Risk
PAHO / WHO calculator. We used descriptive statistics.
RESULTS: We included 99 patientes, fo them, 79.8% were men, with a mean (standard deviation, SD) age
of 44.84 ± 13.55 years and 20.20% were women, with a mean age of 46.15 ± 11.54 years.
The main cardiovascular risk factorx (CVR) found was dyslipidemia (77.78%), followed by AHT (38.38%)
and obesity (56.56%) or overweight (34.34%). Sixty-four pecent of patients with mild OSA, 84% of
patients with moderate OSA and 95% of patients with severe OSA, had 2 or more CVR factors.
When calculating the global CVR at 10 years, 91.92% of the patients had a low CVR, 2.02% moderate and
6.06% very high. No patient had high CVR. The majority of the patients (87.88%) hadtwo or more CVR
factors.
CONCLUSIONES: We highlight the high frequency, as already described in the literature, of CVR factors
and AOS.
The most frequent CVR factors were hypertension, diabetes and obesity
