Study of breast cytology in a tertiary care centre based on Yokohama sytem of reporting breast cytology

Abstract

A total of 200 cases were studied over an 18 month period from March 2022 to September
2023. The lesions were reclassified based on the Yokohama system of reporting breast
cytology. Prior to the introduction of the new system, breast cytology was reported using the
corresponding histological diagnosis which may not be appropriate for the limited diagnostic
material and sampling issues assosciated with cytology reporting. Also the cytology reports did
not offer any risk of malignancy or management guidelines to the treating clinician for further
patient management. The YSRBC attempts to overcome these limitations. Hence, this study
was attempted to validate the feasibility of incorporation of the new system in routine cytology
reporting.
