Comparision of two Cytological Grading Systems with Correlation of Histological Grading System of Breast Carcinoma in a Tertiary Care Centre in South India
Journal Title: Indian Journal of Pathology: Research and Practice - Year 2019, Vol 8, Issue 3
Abstract
Background: Cytological grading is a useful tool in preoperative prognostication of Breast carcinoma and its management. Aim: To cytologically grade breast carcinoma using Robinson’s and Mouriquand’s grading systems, compare each other and determine which correlates well with Modified Scarff-Bloom Richardson (MSBR) histological grading system. Materials and Methods: 60 cases of Breast lumps were studied from January 2007 to January 2012 whose FNAC and biopsy were performed in our institute. Cytological grading was carried out using Robinson and Mouriquand grading systems and were compared with each other and then each of them were correlated with Modified Scarff-Bloom Richardson histological grading system. Concordance and discordance was accordingly noted amongst them. Results: A total of 60 cases were studied, ages ranging from 35-79 years. By Robinson’s system 20%, 56.67% and 23.33% aspirates were graded as grade I, grade II and grade III respectively. Using Mouriquand’s grading 16.67%, 55% and 28.33% aspirates were graded as grade I, grade II and grade III respectively. Agreement between each other was 82.5%. Agreement between Robinson and MSBR histological grading was 89.17% and between Mouriquand and MSBR histological grade was 80%. Diagnostic accuracy of Robinson’s system was 86.67% and specificity was 70% while Mouriquand system showed an accuracy of 76.67% and specificity of 30%. Conclusion: Comprehensive cytological grading of breast carcinomas was possible using Robinson’s and Mouriquand’s cytological grading system and the concordance between them was 65%. Further, of the 2 cytological grading systems Robinson’s was better because of more objective criteria and easy reproducibility.
