Introduction: Since older patients with breast cancer are underrepresented in clinical trials, an oncogeriatric approach is advocated to guide treatment decisions. However, the effect on outcomes is unclear. The aim of this study was to compare treatments and outcomes between patients treated in an oncogeriatric and a standard care setting. Methods: Patients aged ≥ 70 years with early stage breast cancer were included. The oncogeriatric cohort comprised unselected patients from the Moffitt Cancer Center, and the standard cohort patients from a Dutch population-based cohort. Cox models were used to characterize the influence of care setting on recurrence risk and overall mortality. Results: Overall, 268 patients were included in the oncogeriatric and 1932 patients in the standard cohort. Patients in the oncogeriatric cohort were slightly younger, had more comorbidity, and received more adjuvant endocrine therapy and chemotherapy. Oncogeriatric care was associated with a lower risk of recurrence, which remained significant after adjustment for patient and tumour characteristics [hazard ratio (HR) 0.66, 95% confidence interval (CI) 0.44–0.99]. Oncogeriatric care was also associated with a lower overall mortality, which also remained significant after adjustment for patient and tumour characteristics (HR 0.69, 95% CI 0.55–0.87). Conclusions: Patients treated in the oncogeriatric care setting had a lower risk of recurrence, which may be explained by more systemic treatment. Overall mortality was also lower, but other explanations besides care setting could not be ruled out as the cohorts had different patient profiles. Future studies need to clarify the impact of an oncogeriatric approach on outcomes.

Introduction. For postmenopausal patients with hormonesensitive breast cancer, outcome is worse with increasing age at diagnosis. The aim of this study was to assess the incidenceof breast cancer recurrence (locoregionalanddistant), and contralateral breast cancer by age at diagnosis. Methods. Patients enrolled in the Tamoxifen Exemestane Adjuvant Multinational (TEAM) trial were included. Primary endpoints were locoregional recurrence, distant recurrence, and contralateralbreastcancer.Ageatdiagnosiswascategorizedas younger than 65 years, 65-74 years, and 75 years or older. Results. Overall, 9,766 patients were included, of which 5,349 were younger than 65 years (reference group), 3,060 were 65-74 years, and 1,357 were 75 years or older. With increasing age, a decreased administration of radiotherapy after breast conserving surgery (94%, 92%, and 88%, respectively) and adjuvant chemotherapy (51%, 23%, and 5%, respectively) was observed. Risk of distant recurrence increased with age at diagnosis; multivariable hazard ratio for pa

Context: In addition to classic tumor-related prognostic factors, patient characteristics may be associated with breast cancer outcome. Objective: To assess the association between age at diagnosis and breast cancer outcome in postmenopausal women with hormone receptor-positive breast cancer. Design, Setting, and Patients: Study analysis of 9766 patients enrolled in the TEAM (Tamoxifen Exemestane Adjuvant Multinational) randomized clinical trial between January 2001 and January 2006. Age at diagnosis was categorized as younger than 65 years (n=5349), 65 to 74 years (n=3060), and 75 years or older (n=1357). Main Outcome Measures: Primary end point was disease-specific mortality; secondary end points were other-cause mortality and breast cancer relapse. Results: During median follow-up of approximately 5.1 years, there were a total of 1043 deaths. Disease-specific mortality, as a proportion of all-cause mortality, decreased with categorical age group (78% [<65 years], 56% [65-74 years], and 36% [≥75 years]; P < .001). In multivariable analyses, compared with patients younger than 65 years, disease-specific mortality increased with age for patients aged 65 to 74 years (hazard ratio [HR], 1.25; 95% CI, 1.01-1.54); and patients aged 75 years or older (HR, 1.63; 95% CI, 1.23-2.16) (P < .001). Similarly, breast cancer relapse increased with age for patients aged 65-74 years (HR, 1.07; 95% CI, 0.91-1.25 and patients aged 75 years or older (HR, 1.29; 95% CI, 1.05-1.60) (P=.06). Other-cause mortality increased with age in patients aged 65 to 74 years (HR, 2.66; 95% CI, 1.96-3.63) and patients aged 75 years or older (HR, 7.30; 95% CI, 5.29-10.07) (P < .001). Conclusion: Among postmenopausal women with hormone receptor-positive breast cancer, increasing age was associated with a higher disease-specific mortality.

Background. Early discontinuation of adjuvant endocrine therapy may affect the outcome of treatment in breast cancer patients. The aim of this study was to assess age-specific persistence and age-specific survival outcome based on persistence status. Methods. Patients enrolled in the Tamoxifen Exemestane Adjuvant Multinational trial were included. Nonpersistence was defined as discontinuing the
