Fine-needle aspiration biopsy of cervical lymph nodes: factors in predicting malignant diagnosis
Abstract:
The objective of the study was to determine the predicting factors in malignant diagnosis in ultrasonography guided fine-needle aspiration biopsy of cervical lymph nodes. Design is retrospective follow-up study. Ultrasonography guided fine-needle aspiration biopsies of cervical lymph nodes were performed in 290 patients. The mean age was 45.5±14.4 years (range; 15-85). 207 (71.4%) and 83 (28.6%) were women and men, respectively. Cytopathologist was not present in any biopsy procedure. Factors in predicting malignancy were age, gender, presence of primary malignancy, localization (Level 1-6), hypoechogenicity with loss of echogenic hilum, microcalcification, cystic feature, minimum and maximum sizes, and index value (minimum size/maximum size). Factors were analyzed by univariate and multivariable tests. The mean minimum size and index value of the lymph nodes were 10.4±5.5 mm and 0.58±0.18, respectively. Age, gender, microcalcification, cystic feature, minimum size, and index value were poor predictors in malignancy. Predictors were presence of primary malignancy (p
