The New <scp>WHO</scp> Lung Cytopathology Reporting System in Practice: Diagnostic Performance and Risk of Malignancy in a Tertiary Care Setting

The WHO Reporting System provides an effective framework for stratifying respiratory cytology samples. While categories such as malignant and suspicious showed high diagnostic reliability, false negatives in benign and inadequate categories highlight the need for integrated clinical and radiological assessment. Bronchial brush and wash emerged as the most diagnostically accurate specimen types. Further prospective studies are warranted to validate these findings across broader clinical settings.
