Correlation between Modified Bloom Richardson Grade and Lymph Nodal Status in Infiltrating Ductal Type of Breast Carcinoma

Abstract

Introduction: Breast cancer is one of the most common cancers in women. Among the various types, invasive ductal carcinomas (IDC), not otherwise specified (NOS) is the most common type. This study was conducted to describe the clinico-pathological parameters of breast cancer, and to find a correlation between two of the prognostic parameters, i.e., Bloom Richardson (BR) grade and lymph node metastasis. Materials and Methods: It was a cross-sectional study with a sample size of 100 cases. Routine clinical details and investigations of the patients were recorded, including age, TNM stage of tumour, etc. Further, the specimens were evaluated for the histological typing, histological grading, and status of lymph nodes. Also, statistical correlations were established between two of the prognostic parameters, i.e., BR grade and lymph node metastasis. Results: All the cases were NOS type of IDC. Majority of the cases belonged to pTNM stage III, followed by stage II. Maximum cases belonged to BR grade 2, followed by grade 3. Lymph node metastasis was present in 40% cases. A statistically significant correlation was seen between increasing BR grade and presence of lymph node metastasis in the tumour. Discussion and Conclusion: Majority of the cases in our study belong to high grade and stage. This is probably due to lack of awareness and late detection of breast carcinoma in Indian scenario. A statistically significant correlation was found between increasing BR grade and presence of lymph node metastasis in the tumour. Thus, these can be used along with other clinico-pathological parameters for prognostic and therapeutic planning in breast carcinoma cases.
