[Target thin-needle puncture biopsy in diagnosis of thyroid cancer]

One hundred medical histories of patients with thyroid cancer (TC) were analyzed. Patients were divided into two groups depending on the variant of thin-needle biopsy technique (TNB). In group 1TNB was performed with "blind" method (with palpation control)--43 cases, in group 2 target TNB (ultrasound-guided) was carried out--57 cases. Patients of each group were divided depending on cytological presurgical diagnosis. Statistical analysis was carried out with two-sided Fisher's criterion. It is demonstrated that detection of TC in group 2 (84.2%) was higher than in group 1 (62.8%) where "blind" method of puncture was used (p = 0.020). It is recommended to perform target TNB in all cases of nodular goiter that improves quality of TC diagnosis.
