Abstract:
BACKGROUND: Fine needle aspiration cytology is an effective and important diagnostic procedure to distinguish benign from malignant thyroid nodule. The purpose of this study is to compare the results of thyroid fine needle aspiration cytology performed by the residents of family medicine and internal medicine. METHODS: Among patients who underwent fine needle aspiration cytology for differential diagnosis of thyroid nodule at the department of family medicine, Pusan National University Hospital from July 1996 to June 1998, we randomly selected 96 patients. We also selected 96 control patients at the department of internal medicine. We assessed the patients age, sex, accompanying symptoms, diagnostic procedures, pathologic results of fine needle aspiration cytology from the medical records and biopsy records. For statistical analysis, we used t-test and Chi-square test. RESULTS: Mean age of 96 patients of family medicine was 44.4 years. Females were 89(92.7%) and males 7(7.3%). Age and sex distributions were not significantly different from that of internal medicine patients(p>0.05). Patients with thyroid nodule had underwent fine needle aspiration cytology(100.0%), thyroid function test(76.0%), thyroid scan(49.0%), and thyroid ultrasond(35.4%). There were more thyroid scans performed in the intemal medicine department, as there were more ultrasonograms done in the family medicine department(p<0.05). Pathology results of 96 cases showed benign in 51 cases(53.1%), malignant in 8(8.3%), indeterminate in 16(16.7%), and insufficient in 21(21.9%). Among the 51 benign cases, there were cystic nodule(27.1%), adenomatous hyperplasia(22.9%), and thyroiditis(3.1%). All 8 malignant cases were papillary carcinoma. The frequency of malignancy thyroid nodules and insufficient specimens were not significantly different between the two departments(p>0.05). Complications of aspiration were rare and not significantly different between the two departments(p>0.05). CONCLUSIONS: Pathology results and complications of fine needle aspiration cytology performed by residents of family medicine and internal medicine were not significantly different.
