Cancer of unknown primary (CUP) represents a rare oncological and heterogeneous disease in which one or more metastases are present, but the location of the primary site is unknown. Pathological diagnosis, using immunohistochemistry, of such metastatic materials is challenging and frequently does not allow for determining the tissue of origin (ToO)...

Data on all Pap smears collected in the organised screening in 2010-2015 were retrieved from the electronic database and linked with Polish National Cancer Registry (PNCR) data. False-negative results were de...

... Interpretation of a slide as normal, despite the presence of abnormal cells, was pointed out as a reason for FN diagnoses in over 50% of slides in many studies. In a pooled analysis by DeMay, 655 no intraepithelial lesions or malignancy (NILM) slides were evaluated, and 340 of them were reclassified as abnormal (51.9%) [42], which was in line with results obtained by Kenter [44], and, more recently, Komerska et al.

These changes can be attributed to changes in smoking patterns over time-decline in smoking rates by men and increase by women 14,15 . To assure a decrease in tobacco-related female lung cancer mortality rates, more efforts are needed. ...
... Analysis of the trend over several decades indicates a systematic decrease in both morbidity and mortality due to CC in most countries, including Poland [4,5]. This phenomenon has been attributed to improved public awareness and better economic conditions [6,7]. ...
