Two-Year Experience of the Implementation of the Milan for Reporting Salivary Gland Cytopathology at a Private Medical Laboratory

Abstract

This study aimed to present the 2-year experience of the implementation of the Milan System for Reporting Salivary Gland Cytopathology at Alpha Prolipsis Medical Laboratories, a private medical laboratory located in Athens, Greece. A totaI of 102 Fine Needle Aspirations (FNAs) performed since 2018 were included in the study. Reports were issued according to the Milan System for Reporting Salivary Gland Cytopathology. Aspirates were prepared with both conventional and liquid-based cytological methods and were evaluated by two or three Board-certified cytopathologists. Diagnostic reproducibility and accuracy were evaluated. All cases included in this study had histologic follow-up. The diagnostic accuracy of FNA for differentiating between benign and malignant disease according to MSRSGC classification was 93.3%, the specificity was 97.5% and the sensitivity was 82.2%. The positive and negative predictive values were 93.2 and 87.2%, respectively. Our results show that FNA is a valuable examination technique in the preoperative evaluation of salivary gland lesions. The integration of the 2018 Milan System for Reporting Salivary Gland Cytopathology is effective, with an overall accuracy around 95%.
