“…The final aim of the system is to allow continuous improvement in breast cytology interpretation and thus helping the clinician managing the breast lesion [3] . The present study included FNAC samples of 649 female breast lesions making this a smaller study than those done by Montezuma D et al [4] Wong S et al [5] Wai CJ et al [6] Nargund A et al [7] Appuroopa M et al [8] but more cases than Kamatar PV et al [9] and Tejeswini V et al [10] The study by Montezuma D et al [4] was the first to categorize breast lesions by the new system and currently one of the largest studies done on the topic. In the present study histopathology diagnosis was available in 363 cases and these were used for statistical analysis.…”

Introduction: Breast lumps are a common presenting complaint in general practice. Breast cancers are the most common cancers diagnosed over the world along with unfortunate rise in number of mortality due to them. Proper diagnostic evaluation is necessary. The fine needle aspiration cytology (FNAC) examination of breast lumps is important as it can be used either to differentiate between benign and malignant breast lesion or as an adjunct to core needle biopsy. In 2016 the IAC Yokohama five category reporting system was proposed to allow uniform reporting of breast FNA aspirates. Aim: The current study aims to reclassify breast lump aspirates using the proposed Yokohama reporting system and also to assess the risk of malignancy of each category. Materials and Methods: This single institution retrospective study included female breast lump FNAC cases over 4 year period. Clinical details of included cases were recorded from archives. Cytology slides were reevaluated as per new reporting system and the histopathology correlation was done where available. Statistical analysis was performed. Risk of malignancy of each category was calculated. Results: 649 breast FNAC cases were studied of average age 36.97 years. Maximum cases were in benign category followed by malignant category. Fibroadenoma was most common benign diagnosis. The risk of malignancy was 3.17% in benign category and 95.45% in suspicious for malignancy category. The diagnostic accuracy in current study was 97.83%. Conclusion: Use of a standard categorical cytology reporting system will give improved reports for better patient care.

ContextThe Modified Masood Scoring Index (MMSI) categorizes breast fine needle aspirates into four categories non‐proliferative breast diseases (PBD), PBD without atypia, PBD with atypia and carcinoma in situ/carcinoma. The International Academy of Cytology Yokohama System classifies the aspirates into five categories – inadequate, benign, atypical, suspicious, and malignant. Very few studies have been conducted so far to compare the diagnostic accuracy of this system.AimsThe objectives of the study were to classify breast fine needle aspirates according to the MMSI and IAC Yokohama and assess their risk of malignancy (ROM) and performance parameters.Materials and MethodsAll breast FNAs received from June 2020 to May 2023 were classified according to the MMSI and IAC Yokohama. Using histopathological diagnosis as the gold standard, ROM and performance parameters were calculated.ResultsOut of the 559 breast fine needle aspirates, the histopathological correlation was available for 337 cases. The ROM for non‐PBD, PBD without atypia, PBD with atypia and carcinoma in situ/carcinoma categories were 0%, 1.2%, 9.1% and 93%, respectively. The ROM for each of the categories of Yokohama system was 16.6%, 1.1%, 4.3%, 86.2% and 97.6%, respectively. The values for the sensitivity, specificity, PPV, NPV and diagnostic accuracy were slightly higher for IAC Yokohama (97.3%, 97.2%, 94.7%, 98.6% and 97.2%, respectively) than the MMSI (96.4%, 96.2%, 93%, 98.1% and 96.3%, respectively). Furthermore, another shortfall of MMSI is the inability to compare the Inadequate category of the Yokohama system.ConclusionOverall Yokohama system proved to be a better system for categorizing breast lesions on FNAB as the scoring system provides more objective categorization and minimizes false positive and false negative cases.

Introduction: Fine-needle aspiration cytology (FNAC) is a simple, minimally invasive, and effective tool that can be used to accurately diagnose benign and malignant lesions of the breast. The International Academy of Cytologists Yokohama system and Modified Masood’s Scoring Index (MMSI) are two important systems to categorize palpable breast lesions on FNAC. The goal of the present study was to evaluate the IAC Yokohama system and MMSI in the cytological diagnosis and classification of diverse breast lesions and to compare the diagnostic accuracy of both systems through cyto-histological correlation. Methods: A retrospective cross-sectional study was done within the 3-year period from 2019 to 2021. Seven hundred and ninety cases of FNAC breast lesions were included and were categorized following the recommendations by the International Academy of Cytologists Yokohama system and MMSI. The sensitivity, specificity, accuracy, positive predictive value (PPV), negative predictive value (NPV), and diagnostic accuracy for both systems were calculated, taking histopathology as the standard. Additionally, the risk of malignancy (ROM) of each category was calculated in the Yokohama system. Results: The IAC Yokohama system’s sensitivity, specificity, PPV, NPV, and diagnostic accuracy were 96.8, 95.8%, 96%, 96.6%, and 96.3%. The MMSI had sensitivity, specificity, PPV, NPV, and diagnostic accuracy of 95.8%, 98.4%, 98.3%, 96.1%, and 97.1%, respectively. The ROM for insufficient, benign, atypical, suspicious for malignancy, and malignant categories were 12.5%, 1.8%, 20%, 90.4%, and 97.5%, respectively. Conclusion: The categorization of breast lumps using the MMSI is more accurate and more specific in diagnosing malignant cases, and thus, the MMSI system is more precise and accurate at diagnosing malignant cases.
