Objective: The study aim was to investigate the methods of breast cancer diagnosis and treatment for women at advanced ages., Methods: We identified 134 patients ≥ 80 years old treated for breast cancer. Data included patient and tumor characteristics, treatment, and outcomes., Results: Of 134 women ≥ 80 years old, 146 breast cancers were diagnosed. Sixty-five (45%) were detected by mammography. Surgical therapy included partial mastectomy in 50% and mastectomy in 50%. Although 12 (9%) women had no axillary staging, 22 (16%) underwent axillary lymph node dissection for node-negative disease. Of 73 patients undergoing partial mastectomy, 34 (47%) received adjuvant radiation. Of 113 cancers with known estrogen receptor (ER) status, 83% were ER positive; 95% received endocrine therapy. Fourteen (10%) received adjuvant chemotherapy. Eleven (8%) were Her-2 neu-amplified; one patient received adjuvant trastuzumab. At follow-up, 87 (65%) patients were alive without evidence of disease, while 6 (4%) died of breast cancer., Conclusions: Breast cancer in women ≥ 80 years is more likely to be early-stage with favorable tumor biology. While most women eligible for anti-estrogen therapy received it, adjuvant radiation, chemotherapy, and/or trastuzumab were utilized infrequently. Despite these variations, older women with breast cancer are unlikely to suffer breast cancer-related mortality., (Copyright © 2010 Wiley-Liss, Inc.)

Background and Objectives: The goal of the current study was to determine whether MRI impacts multidisciplinary treatment planning and if it leads to increased mastectomy rates., Methods: A retrospective review was conducted of 441 patients treated for breast cancer between January 2005 and May 2008 who underwent breast MRI. Data included number of additional findings and their imaging and pathologic work-up. This was analyzed to determine impact of MRI on treatment planning., Results: Of 441 patients, 45% had > or =1 additional finding on MRI. Of 410 patients with complete records, 29% had changes in the treatment plan, including 36 patients who were initially considered for breast conservation but proceeded directly to mastectomy based on MRI findings of suspected multicentricity. Twenty-three of those patients did not have a biopsy of the MRI lesion, with 87% having unicentric disease on final pathology. Overall, the mastectomy rate was 44%, which was significantly increased compared to patients not undergoing MRI (32%, P < 0.05)., Conclusions: Breast MRI alters the treatment planning for many patients with newly diagnosed breast cancer. Mastectomy rates are increased when MRI results alone direct surgical planning. Biopsy of MRI-identified lesions should be performed to avoid over-treatment.

Background: The goal of the current study is to identify predictors responsible for mortality disparities between young (< or =40 years) and older (>40 years) women with breast cancer., Methods: From 1998 to 2006, 344 patients < or =40 years were treated for breast cancer. Cox regression models calculated adjusted hazard ratios (aHR) and 95% confidence intervals (CI) to determine differences in breast cancer mortality in women < or =40 years versus >40 years (n = 3,252), controlling for potential confounders in univariate tests., Results: From 1998 to 2006, 3,596 patients were treated for breast cancer; 9.6% were < or =40 years and 90.4% were >40 years. Young women were more likely to be African-American, with a family history of breast cancer, diagnosed at advanced stage, and treated by mastectomy (P < 0.05). Tumors in young women were more likely to be bilateral, T2/T3, grade III, ER/PR negative, and lymph-node positive (P < 0.01). Overall, young women (< or =40 years) with breast cancer were more likely to die compared with older women (>40 years) (aHR 1.52, CI 1.37-1.74)., Conclusions: Young women (< or =40 years) with breast cancer are diagnosed at a more advanced stage and have tumors with poor prognostic features. Young women (< or =40 years) are 52% more likely to die from breast cancer compared to older women (>40 years).
