Abstract

Objective. To assess the comparability of the cytological and histological studies of material of different localizations.

Materials and methods. The work is based on the analysis of results of cytological and histological studies in 48 patients examined at Perm Regional Oncological Dispensary in 2019.

Results. It was established that out of 22 mammary punctates, diagnosis of “cancer” was confirmed in 20 patients with coincidence validity criterion of 91 %. Out of 14 preparations of skin, 13 cases were histologically confirmed that constituted 92.8 %. When studying the lymph node punctate, one mismatch was detected. Out of 6 thyroid punctates, there were 5 confirmed ones. Percentage of false-positive cytological conclusions was on average 7 %, false-negative – 1 %.

Conclusions. Comparability of cytological and histological studies according to the results of data analysis ranged from 50 to 100 % depending on localization and was on average 91.6 %.
