The Milan System for Reporting Salivary Gland Cytopathology: A Comprehensive Guide

The Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) is a standardized reporting system designed to enhance the accuracy, consistency, and clinical utility of salivary gland cytopathology. It provides a structured framework for evaluating and categorizing salivary gland lesions based on their cytological features, facilitating effective communication between cytopathologists and clinicians.

Background

The MSRSGC was developed in response to the limitations of traditional salivary gland cytopathology reporting systems, which often lacked standardization and led to variability in interpretations. The system was first proposed in 2010 by a panel of experts at the International Academy of Cytopathology (IAC) and has since gained widespread adoption.

Components of the Milan System

The MSRSGC consists of several key components:

• Specimen adequacy assessment: Determines whether the sample is sufficient for evaluation and provides guidance on additional sampling if necessary.
• Diagnostic categories: Classifies lesions into six diagnostic categories based on their cytological features:
• Non-neoplastic
• Atypia of undetermined significance (AUS)
• Benign
• SUSPICIOUS for malignancy
• Malignant
• Insufficient for diagnosis
• Subcategories and ancillary tests: Provides additional information within diagnostic categories, such as specific tumor types or the use of ancillary tests (e.g., immunocytochemistry, molecular studies).
• Clinical follow-up recommendations: Outlines recommended clinical management and follow-up intervals based on the diagnostic category.

Diagnostic Categories

The six diagnostic categories of the MSRSGC are defined as follows:

1. Non-neoplastic: Cytological features are consistent with a benign, inflammatory, or reactive process. Clinical correlation is essential to rule out underlying lesions.
2. Atypia of undetermined significance (AUS): Cytological features exhibit atypia that cannot be definitively classified as benign or malignant. Close clinical follow-up and consideration of additional sampling may be warranted.
3. Benign: Cytological features are characteristic of a specific benign salivary gland lesion, such as pleomorphic adenoma or Warthin's tumor. No further diagnostic evaluation is usually required.
4. SUSPICIOUS for malignancy: Cytological features raise suspicion of malignancy but are not conclusive. Additional diagnostic procedures, such as biopsy, are strongly recommended.
5. Malignant: Cytological features are eindeutig for malignancy. Immediate biopsy and appropriate treatment are indicated.
6. Insufficient for diagnosis: The sample is inadequate for evaluation, or the cytological features are inconclusive. Repeat sampling and/or alternative diagnostic methods may be necessary.

Interpretation and Clinical Utility

The MSRSGC provides a standardized framework for interpreting salivary gland cytopathology specimens, facilitating consistent reporting and communication between cytopathologists and clinicians. By categorizing lesions based on their cytomorphological features and recommending appropriate follow-up, the MSRSGC enhances the accuracy and clinical utility of salivary gland cytopathology.

The system has been shown to improve interobserver agreement in salivary gland cytopathology reporting and to guide clinical management decisions more effectively. It has also been incorporated into electronic reporting systems, further enhancing its accessibility and usability.

The Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) is a valuable tool for cytopathologists and clinicians alike. By providing a structured reporting framework, the MSRSGC enhances the accuracy and consistency of salivary gland cytopathology and facilitates effective communication and clinical decision-making. As cytopathology continues to evolve, the MSRSGC will likely remain an essential component of salivary gland cytopathology practice.
