ABSTRACT

Objective: To determine whether malignancy criteria are precise and their value in our population.
Setting: Third level health care hospital.
Design: Retrospective, transversal, comparative study.
Patients and methods: We reviewed the clinical files of 300 patients with thyroid nodules and who had been operated on. We analyzed the following malignancy criteria: evolution time, pain, dysphagia, dysnea, dysphonia, growth velocity, history of previous radiation, familial antecedents of thyroid cancer, size, consistency, fixation to other planes, presence of cervical ganglia, hypersensitivity and functional state. These results were compared with those obtained from the definite histopathological study.
Results: The population studied consisted of 282 women (94%) and 18 men (6%), average age of 42. We found 212 (70%) benign nodules, 202 women and 10 men; the malignant nodules amounted to 88 (29%), 80 women and 8 men. Average evolution time for all patients was 44 months; for the benign nodules, 46 months and for the malignant ones of 38 months, no statistically significant difference was found. The average size of the nodule was 10.1 mm, the benign ones measured 10.5 mm and the malignant ones 9.3 mm. There were neither differences in regard to fixation to deep planes, mobility or consistency. The difference was significant in regard to the presence of cervical ganglia in patients with malignant nodules.
Conclusion: The studied clinical criteria, except for the presence of cervical ganglia, are not reliable to determine malignancy of a nodule.
