94 Background: Octogenarian breast cancer (BrCa) patients accept less aggressive BrCa treatment due to decreased life expectancy, increased comorbidities, and high likelihood of death from other causes. Unfortunately little data exist stratifying octogenarian outcomes by disease risk. We sought to characterize treatment and recurrence patterns in patients >80yo. Methods: Retrospective review identified 432 women >80yo treated surgically for stage 0-3 BrCa between 11/99-8/11. We gathered clinicopathologic data and classified patients by disease risk as DCIS only, low risk (<2cm and ER positive and node negative), or high risk (>2cm or ER negative or node positive). We compared recurrence rates and estimated survival by Kaplan-Meier curves. Results: Among the 432 women, disease was found by mammogram in 86%, treated with BCT in 64%, and predominantly ER-positive (87%). We classified patients as having DCIS only (N=61), low risk (N=205), or high risk (N=166) disease. We identified the following deviations from standard treatment guidelines: 68% DCIS BCT and 38% high risk BCT patients did not have radiation therapy, 25% low risk BCT patients had surgery only, 51% low risk patients did not take adjuvant hormonal therapy, and 40% high risk patients had no adjuvant chemo/hormonal therapy. At 5 and 10 years the overall estimated survival was 63% and 31%, respectively. Overall, 19/432 (5%) patients developed recurrence (table 1). Patients needing mastectomy for high risk disease had significantly higher risk of recurrence than high or low risk BCT patients (p=0.02). Of the 19 recurrence patients, 7/19 (37%; 1 DCIS, 1 low risk, 5 high risk) occurred despite standard multimodality treatment, while12 (63%; 3 low risk, 9 high risk) had the initial tumor treated less aggressively due to patient choice (n=9) or medical co-morbidities (n=3). Conclusions: Significant deviations from treatment guidelines occur in women >80yo. Those with high risk disease should be counseled accordingly and encouraged to receive adjuvant treatment as two thirds of women >80yo will live at least 5 years. [Table: see text]

Purpose: Mycotic aortic aneurysms are rare but are associated with high morbidity and mortality due to their propensity for rupture. Traditional therapy consists of open surgical repair with resection and aortic reconstruction or extra-anatomic bypass combined with long-term antibiotic therapy. Case report: An 85-year-old male with persistent bacteremia was found to have a descending mycotic aortic aneurysm. Surgical options were discussed and endovascular treatment was recommended with stent-graft placement followed by intra-aortic rifampin infusion. This approach led to resolution of the aneurysm and eradication of bacteremia at 4-month follow-up. Conclusion: By combining traditional surgical strategies with a contemporary endovascular approach, the perioperative mortality and long-term risk of infection associated with mycotic thoracic aneurysms can potentially be decreased.
