Background A decline in physical activity and the ability to perform activities of daily living (ADL) and instrumental activities of daily living (IADL) could interfere with independent living and quality of life in older patients, but may be prevented with tailored interventions. The aim of the current study was to assess changes in physical activity and ADL/IADL in the first 5 years after breast cancer diagnosis in a real-world cohort of older patients and to identify factors associated with physical decline. Methods Patients aged ≥70 years with in situ or stages I-III breast cancer were included in the prospective Climb Every Mountain cohort study. Linear mixed models were used to assess physical activity (according to Metabolic Equivalent of Task (MET) hours per week) and ADL/IADL (according to the Groningen Activity Restriction Scale (GARS)) over time. Secondly, the association with geriatric characteristics, treatment, quality of life, depression, apathy, and loneliness was analyzed. Results A total of 239 patients were included. Physical activity and ADL/IADL changed in the first 5 years after diagnosis (mean change from baseline −11.6 and +4.2, respectively). Geriatric characteristics at baseline were strongly associated with longitudinal change in physical activity and ADL/IADL, whereas breast cancer treatment was not. A better quality of life was associated with better physical activity and preservation of ADL/IADL, while depression and loneliness were negatively associated with these outcomes. Discussion Geriatric characteristics, loneliness, and depressive symptoms were associated with physical decline in older patients with breast cancer, while breast cancer treatment was not.

Background: Studies have demonstrated worse breast cancer‐specific mortality with older age, despite an increasing risk of dying from other causes due to comorbidity (competing mortality). However, findings on the association between older age and recurrence risk are inconsistent. The aim of this study was to assess incidences of locoregional and distant recurrence by age, taking competing mortality into account. Materials and Methods: Patients surgically treated for nonmetastasized breast cancer between 2003 and 2009 were selected from The Netherlands Cancer Registry. Cumulative incidences of recurrence were calculated considering death without distant recurrence as competing event. Fine and Gray analyses were performed to characterize the impact of age (70–74 [reference group], 75–79, and ≥80 years) on recurrence risk. Results: A total of 18,419 patients were included. Nine‐year cumulative incidences of locoregional recurrence were 2.5%, 3.1%, and 2.9% in patients aged 70–74, 75–79, and ≥80 years, and 9‐year cumulative incidences of distant recurrence were 10.9%, 15.9%, and 12.7%, respectively. After adjustment for tumor and treatment characteristics, age was not associated with locoregional recurrence risk. For distant recurrence, patients aged 75–79 years remained at higher risk after adjustment for tumor and treatment characteristics (75–79 years subdistribution hazard ratio [sHR], 1.25; 95% confidence interval [CI], 1.11–1.41; ≥80 years sHR, 1.03; 95% CI, 0.91–1.17). Conclusion: Patients aged 75–79 years had a higher risk of distant recurrence than patients aged 70–74 years, despite the higher competing mortality. Individualizing treatment by using prediction tools that include competing mortality could improve outcome for older patients with breast cancer. Implications for Practice: In this population‐based study of 18,419 surgically treated patients aged 70 years or older, patients aged 75–79 years were at higher risk of distant recurrence than were patients aged 70–74 years. This finding suggests that patients in this age category are undertreated. In contrast, it was also demonstrated that the risk of dying without a recurrence strongly increases with age, and patients with a high competing mortality risk are easily overtreated. To identify older patients who may benefit from more treatment, clinicians should therefore take competing mortality risk into account. Prediction tools could facilitate this and thereby improve treatment strategy. Evidence suggests that age is an independent risk factor for worse breast cancer outcome. This study assessed the incidence of locoregional and distant recurrence by age at diagnosis among patients aged ≥70 years, while taking competing mortality risks into account.

Background: The aim was to study the impact of comorbidities and age on breast cancer mortality, taking into account competing causes of death. Subjects, Materials, and Methods: Cohort analysis of Dutch and Belgian patients with postmenopausal, early hormone receptor‐positive breast cancer included in the Tamoxifen and Exemestane Adjuvant Multinational (TEAM) trial between 2001 and 2006. This is a randomized controlled trial of patients who had completed local treatment with curative intent and were randomized to receive exemestane for 5 years, or sequential treatment of tamoxifen followed by exemestane for a duration of 5 years. Patients were categorized by number of comorbidities (no comorbidities, 1–2 comorbidities, and >2 comorbidities) and age (<70 years and ≥70 years). Main outcome was breast cancer mortality considering other‐cause mortality as competing event; cumulative incidences were calculated using the Cumulative Incidence Competing Risk Methods, and the Fine and Gray model was used to calculate the effect of age and comorbidities for the cause‐specific incidences of breast cancer death, taking into account the effect of competing causes of death. Results: Overall, 3,159 patients were included, of which 2,203 (69.7%) were aged <70 years and 956 (30.3%) were aged ≥70 years at diagnosis. Cumulative incidence of breast cancer mortality was higher among patients ≥70 without comorbidities (22.2%, 95% CI, 17.5–26.9) compared with patients <70 without comorbidities (15.6%, 95% CI, 13.6–17.7, reference group), multivariable subdistribution hazard ratio (sHR) 1.49 (95% CI, 1.12–1.97, p =.005) after a median follow‐up of 10 years. Use of chemotherapy was lower in older patients (1%, irrespective of the number of comorbidities) compared with younger patients (50%, 44%, and 38% for patients with no, 1–2, or >2 comorbidities, p <.001). Conclusion: Older patients without comorbidities have a higher risk of dying due to breast cancer than younger counterparts, even when taking into account higher competing mortality, while use of chemotherapy in this group was low. These findings underline the need to take into account comorbidities, age, and competing mortality in the prognosis of breast cancer for accurate decision making. Implications for Practice: Older patients without comorbidity are at increased risk of dying from breast cancer, despite a higher other‐cause mortality. This study shows that including age and comorbidity for the assessment of breast cancer mortality and other‐cause mortality is indispensable for treatment decision making in older patients. Future prognostic tools for breast cancer prognosis should incorporate these items as well as risk of toxicity of adjuvant chemotherapy to adequately predict outcomes to optimize personalized treatment for older patients with early breast cancer. This analysis of TEAM trial data focuses on the effects of comorbidities and age on breast cancer mortality and other cause mortality after 10 years of follow‐up, taking into account competing causes of death.

Abstract: Background: Colon cancer in older patients represents a major public health issue. As older patients are hardly included in clinical trials, the optimal treatment of these patients remains unclear. The present international EURECCA comparison explores possible associations between treatment and survival outcomes in elderly colon cancer patients. Subjects, Materials, and Methods: National data from Belgium, Denmark, The Netherlands, Norway, and Sweden were obtained, as well as a multicenter surgery cohort from Germany. Patients aged 80 years and older, diagnosed with colon cancer between 2001 and 2010, were included. The study interval was divided into two periods: 2001–2006 and 2007–2010. The proportion of surgical treatment and chemotherapy within a country and its relation to relative survival were calculated for each time frame. Results: Overall, 50,761 patients were included. At least 94% of patients with stage II and III colon cancer underwent surgical removal of the tumor. For stage II–IV, the proportion of chemotherapy after surgery was highest in Belgium and lowest in The Netherlands and Norway. For stage III, it varied from 24.8% in Belgium and 3.9% in Norway. For stage III, a better adjusted relative survival between 2007 and 2010 was observed in Sweden (adjusted relative excess risk [RER] 0.64, 95% confidence interval [CI]: 0.54–0.76) and Norway (adjusted RER 0.81, 95% CI: 0.69–0.96) compared with Belgium. Conclusion: There is substantial variation in the rate of treatment and survival between countries for patients with colon cancer aged 80 years or older. Despite higher prescription of adjuvant chemotherapy, poorer survival outcomes were observed in Belgium. No clear linear pattern between the proportion of chemotherapy and better adjusted relative survival was observed. Implications for Practice: With the increasing growth of the older population, clinicians will be treating an increasing number of older patients diagnosed with colon cancer. No clear linear pattern between adjuvant chemotherapy and better adjusted relative survival was observed. Future studies should also include data on surgical quality. [ABSTRACT FROM AUTHOR]

Background. Previous retrospective studies have shown that physical functioning in older cancer survivors is affected after treatment, yet prospective data are lacking. The aim of this study was to assess change in physical functioning in different age groups of patients with hormone receptor-positive breast cancer who were enrolled in the Tamoxifen Exemestane Adjuvant Multinational (TEAM) phase III trial. Methods. Two physical parameters were assessed. Physical functioning was assessed using the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 questionnaire 1 year (T1) and 2 years (T2) after diagnosis. Physical activity was measured in metabolic equivalent of task (MET) hours/week at T1 and T2. Physical activity before diagnosis (T0) was assessed retrospectively at the T1 questionnaire. Patients were divided into three age groups: <60, 60-69, and ≥70 years. Decline in physical functioning was assessed using linear regression analysis. Differences in mean values of physical activity levels were calculated using repeated-measures one way analysis of variance. Results. A total of 431 patients were included for analysis. In all age groups, physical activity levels at T1 and T2 were significantly lower than prediagnostic physical activity levels (T0) (p < .001 for all age groups). Age ≥70 years was independently associated with decline in physical functioning between T1 and T2 (β = 24.62, 95% confidence interval -8.73 to -0.51, p = .028). Conclusion. Patients aged 70 years or older treated with breast surgery and adjuvant hormonal therapy did not improve between years 1 and 2 after diagnosis to the same extent as did younger patients.

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 incidence of breast cancer recurrence (locoregional and distant), 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 contralateral breast cancer.Age at diagnosis was categorized as 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 patients aged 65-74 years was 1.20 (95% confidence interval [CI]: 1.00 -1.44), hazard ratio for patients aged 75 years or older was 1.39 (95% CI: 1.08 -1.79). Risks of locoregional recurrence and contralateral breast cancer were not significantly different across age groups. Conclusion. Elderly patients with breast cancer were at increased risk for distant recurrence. Other studies have shown that the risk of distant recurrence is mainly affected by adjuvant systemic therapy. All TEAM patients received adjuvant endocrine treatment; however, chemotherapy was administered less often in elderly patients. These findings are suggestive for consideration of chemotherapy in relatively fit elderly breast cancer patients with hormonesensitive disease. [ABSTRACT FROM AUTHOR]

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 assigned endocrine treatment within 1 year of follow-up because of adverse events, intercurrent illness, patient refusal, or other reasons. Endpoints were the breast cancer-specific and overall survival times. Analyses were stratified by age at diagnosis (<65 years, 65-74 years, ≥75 years). Results. Overall, 3,142 postmenopausal breast cancer patients were included: 1,682 were aged <65 years, 951 were aged 65-74 years, and 509 were aged ≥75 years. Older age was associated with a higher proportion of nonpersistence within 1 year of follow-up. In patients aged<65 years, nonpersistent patients had lower breast cancer- specific and overall survival probabilities. In patients aged 65-74 years and patients aged ≥75 years, the survival times of persistent and nonpersistent patients were similar. Conclusion. Nonpersistence within 1 year of follow-up was associated with lower breast cancer-specific and overall survival probabilities in patients aged <65 years, but it was not associated with survival outcomes in patients aged 65-74 years or in patients aged>75 years. These results suggest that extrapolation of outcomes from a young to an elderly breast cancer population may be insufficient and urge age-specific breast cancer studies. [ABSTRACT FROM AUTHOR]

Background. The number of elderly women with breast cancer is increasing and will become a major health concern. However, little is known about the optimal treatment for this age group. The aim of this study was to describe time trends for the overall Dutch breast cancer cohort with an emphasis on differences between young and elderly patients. Methods. All adult female patients diagnosed in 1995- 2005 were selected from the Netherlands Cancer Registry. Relative excess risks for death (adjusted for stage, histology, treatment, and grade) were estimated using a multivariate generalized linear model with a Poisson distribution, based on collapsed relative survival data, using exact survival times. Results. Overall, 127,805 patients were included. Treatment of patients aged ≥75 years changed significantly over time: they received less surgery, more adjuvant hormonal treatment and chemotherapy, and more hormonal treatment without surgery. In contrast to younger patients, the relative survival did not improve significantly over time for elderly patients. With increasing age, the observed--expected death ratio decreased to almost 1.0. Conclusion. Survival for elderly patients with breast cancer did not improve significantly. Observed- expected death ratios in the elderly are close to 1, indicating that excess mortality is low. Elderly patients with breast cancer have a higher risk for overtreatment and undertreatment, with a delicate therapeutic balance between breast cancer survival gain and potential toxicities. To improve breast cancer survival in the elderly, a critical reappraisal is needed of costs and benefits of hormonal as well as other treatments, and better selection of patients who can benefit from available therapies is warranted.
