Correlation of Breast Density Grade on Mammogram With Diagnosed Breast Cancer: A Retrospective Cross-Sectional Study

Objective The objective of this study is to determine any association between mammographic density (MD) and breast cancer in Pakistani population. The study will also investigate relationship between mammographic breast density, clinical characteristics, and molecular tumor markers of the disease. M...

Sumario:Objective The objective of this study is to determine any association between mammographic density (MD) and breast cancer in Pakistani population. The study will also investigate relationship between mammographic breast density, clinical characteristics, and molecular tumor markers of the disease. Methods A retrospective review of data was carried out from January 2020 to December 2020 with stage 0-3 patients with histologically proven breast cancer included in the study. Mammograms were reviewed and density grade was recorded in accordance with "Breast Imaging Reporting and Data System (BIRADS)" guidelines. Patient age, tumor, and receptor characteristics were studied and their association with mammographic density was investigated by using chi-square test. P-value ≤0.05 was considered statistically significant. Results A total of 361 patients were included with a mean age of 46 years. The frequencies of BIRAD categories were as follows: category A: 8.9%, category B: 43.2%, category C: 33.5%, and category D: 14.4%. Cumulative frequency of categories B and C was 76.7%. There is a statistically significant p-value ≤0.05 association observed between age, estrogen receptors (ER) status, and T-stage versus MD. Also, majority of our patients were in T-stage category 2 or 3, which can easily be picked on mammogram. Conclusion Most of the breast cancer patients in our population had a mammographic density of B or C, indicating that breast cancer is more common in dense breasts. Strong significant association of mammographic density with age, ER status, and tumor stage was found in our population. Future studies need to address and confirm MD and its association with subtypes and aggressiveness of breast cancer.
