    Abstract:
    INTRODUCTION: We review a methodology for detection of malignancy in thyroid gland surgery, comparing clinical exploration, ultrasonography, gammagraphy, fine-needle aspiration (FNA) and extemporaneous biopsy with the definitive pathological results. MATERIAL AND METHODS: We carried out a retrospective study on a sample of 433 (N=433) patients who had been intervened due to thyroid gland disease at the same ENT centre between 1999 and 2004. We collected information focusing on the characteristics of cervical exploration, ultrasonography, gammagraphy, FNA, extemporaneous biopsy and definitive pathological results. RESULTS: With N=433, the male/female ratio was approximately 1/9 (m/f 1/9), the average age was 45.5 years, with a range between 13 and 87 years, and with 20.3% of referred family history of thyroid gland disease; the cervical exploration, ultrasonography ang gammagraphy were not good tests for the screening of malignancy; FNA and extemporaneous biopsy offered 74% and 81% of sensitivity (Se), and 73% and 92% of specificity (Sp) in the detection of malignancy. The specific sensitivities towards papillary carcinoma of FNA and extemporaneous biopsy were 81% and 88%, whilst for follicular carcinoma they were 66% and 62.5%, respectively. CONCLUSIONS: FNA has good sensitivity in clinical suspicion of thyroid papillary carcinoma, although it should be complemented by extemporaneous biopsy due to its better specificity. In the case of follicular carcinoma there is a tendency towards conservative treatment, without carrying out extemporaneous biopsy previously and with reintervention in case of definitive malignancy.
