OCHOA TORRES, Francisco  y  GIL LEON, Rebeca. Fine needle biopsy without aspiration in the presurgical diagnosis of thyroid nodule. Rev Cubana Endocrinol [online]. 2001, vol.12, n.3, pp.139-144. ISSN 1561-2953.

A group of 100 patients operated on of thyroid nodule at the Service of General Surgery of “Comandante Manuel Fajardo” Hospital was studied aimed at validating the method of biopsy by fine needle puncture without aspiration (cytopuncture) in the presurgical diagnosis of this disease. Every patient underwent cytopuncture with needle No. 25 before the operation. The results were classified into negative (benign) and positive (malignant and suspected), and postoperative histology into benign and malignant, according to the interests of our investigation and to the criteria preestablished at the Department of Pathological Anatomy of the hospital. 100 % of the samples were useful for the diagnosis with a correspondence between cytopuncture and histology of 83 %. The values of the indicators of validation were: sensitivity, 76 %; specificity, 85 %; positive predictive value, 57 %, negative predictive value, 93 %; and general efficiency of the method, 85 %. It was concluded that cytopuncture is a useful diagnostic method in the unique thyroid nodule and that it has the same results as the fine needle biopsy, but the first one is more recommendable because its application is easier and it is less traumatic and more economic.
