Purpose: To document the mammographic breast density (MBD) distribution of Jordanian women and the relationship with MBD with age. Correlation between breast cancer diagnosis and density was also explored. Methods: A retrospective review of 660 screening mammograms from King Abdullah University Hospital was conducted. Mammograms were classified into 2 groups: normal (return to routine screening) and breast cancer and rated using the American College of Radiology (ACR) Breast Imaging-Reporting and Data System (BI-RADS) 5th edition for MBD. The association between MBD and age was assessed by descriptive analyses and Kruskal-Wallis test. To compare between normal and breast cancer groups, chi-square post hoc tests with Bonferroni adjustment was used. Results: Groups consisted of 73.9% (n = 488) normal group and 26.1% (n = 172) breast cancer group. A significant inverse relationship was demonstrated between age and MBD among the normal (r = −.319, P <.01) and breast cancer group (r = −.569, P <.01). In total, 69% (n = 336) of women in the normal group and 71% (n = 122) in the breast cancer group and 79.1% (n = 159) of the normal group and 100% (n = 48) of the breast cancer group aged 40 to 49 years reported high MBD (ACR BI-RADS c or d). Conclusions: Most of women in both the normal and breast cancer groups evidenced increased MBD. Increased MBD was inversely proportional to age. As MBD has a known link to increased breast cancer risk and the decreased sensitivity of mammography and it is vital that future screening guidelines for Jordanian women consider the unique breast density distribution of this population.

Introduction: Breast cancer is the most common cancer among Egyptian women. The disease is often advanced at diagnosis. Since molecular profiling is not feasible in routine practice, we sought to examine the association of age distribution with hormone receptor profile, disease stage and outcome among Egyptian women. Patients and methods: We conducted a retrospective review of breast cancer patients treated at Mansoura University Cancer Center in the Nile Delta from 2006 through 2011. Age groups were examined in relation to hormone receptors status and tumor clinicopathological criteria. Additionally, the effect of receptor status on disease relapse and disease-free survival was examined with logistic regression and Kaplan-Meier analysis. Results: A total of 263 patients were included in the current analysis. About 66.9% (n = 176) of patients were hormone receptor positive, 14.1% (n = 37) were Her2/neu positive, and 19.0% (n = 50) were triple negative. Median age of the patients was 52 years and was equal across all receptor status types. Triple negative status correlated with increased risk of disease relapse (odds ratio = 1.8, P = 0.03) and with shortened disease-free survival (hazards ratio = 2.6, P < 0.01). Conclusion: The age distribution and receptor status pattern in the Nile Delta region does not explain the aggressive behavior of the disease. The age of the patients at diagnosis is older than patients in earlier studies from Egypt emphasizing the importance of implementing mammographic screening programs. [ABSTRACT FROM AUTHOR]
