The incidence of cervical intraepithelial neoplasia and its 
correlation with the results of histopathological examination 
in the female population of the Podlaskie Voivodeship

Introduction: Cervical cancer was the seventh most common malignant tumor among women 
in the Podlaskie Voivodeship in 2016. The development of this cancer is preceded by the 
occurrence of cervical intraepithelial neoplasia (CIN). Pap smear is still the basic method 
of secondary prevention of cervical cancer. If the result of the Pap test is positive, further 
diagnosis is necessary (colposcopy, histopathological examination).
Aim: The aim of the study was to assess the incidence of intraepithelial cervical lesions and 
its correlation with the results of histopathological examination in the female population of the 
Podlaskie Voivodeship. 
Material and methods: 51,136 Pap smear tests were analyzed (retrospectively). The tests were 
performed in the Podlaskie Voivodeship from January 2012 to December 2019. Of this group, 
134 patients had a histopathological examination. The results of both studies were compared.
Results: Among the cytological tests performed in private offices, incorrect results accounted 
for 1.35%. The value is two times lower than in the case of tests carried out in the prevention 
program in Podlaskie Voivodeship. The results were consistent in 77% of patients diagnosed 
with HSIL and in 35% of patients diagnosed with LSIL.
Conclusions: The obtained congruence of cytological and histopathological results 
is comparable to the data in the literature. The creation of a central registry of pap smears 
would be helpful in the quality monitoring and the number of abnormal results.
