Healthcare professionals' preferences for surgery or primary endocrine therapy to treat older women with operable breast cancer

Introduction : Primary endocrine therapy (PET) is an alternative treatment to surgery for oestrogen receptor (ER) positive operable breast cancer in older women. However, there is variable use of PET in the UK, with up to 40% of patients aged over 70 receiving PET instead of surgery in some regions. Treatment options offered to patients rely heavily on healthcare professional (HCP) assessment and opinion on which treatments are appropriate. Materials and methods : This was a mixed methods study combining semi-structured interviews with HCPs working in high and low PET regions in the UK, followed by a postal questionnaire survey distributed via the Association of Breast Surgery (ABS). Results : Thirty-four HCPs (20 breast surgeons; 13 nurse specialists; 1 geriatrician) were interviewed from 14 sites across the UK and 252/641 questionnaires returned (39%). There was an overriding view that PET is not suitable for patients under the age of 80 unless there are significant comorbidities. Opinion was split regarding the best way to treat patients with dementia. Patient preference was generally stated to be the most important factor when considering treatment, however only around a quarter 65/244 (26.6%) felt that all patients over the age of 70 should be offered PET as an alternative treatment option. Conclusions : Opinions differ on the best way to treat women over 70 with operable breast cancer, especially if they have co-existing dementia, as well as whether they should be offered PET as a treatment option. This may be a significant cause of treatment variation in the UK. Keywords : Breast cancer; Primary endocrine therapy; Surgery; Elderly; Older; Mixed methods.</p

Opportunities and priorities for breast surgical research

The Breast Cancer Campaign Gap analysis (2013) established breast cancer research priorities without specific focus on surgical research nor the role of surgeons. The majority of breast cancer patients encounter a surgeon at diagnosis or during treatment, thus surgical involvement in design and delivery of high-quality research to improve patient care is critical. This review aims to identify opportunities and priorities for breast surgical research to complement the previous gap analysis

Stage and treatment variation with age in postmenopausal women with breast cancer: compliance with guidelines

Breast cancer-specific mortality is static in older women despite having fallen in younger age groups, possibly due to lack of screening and differences in treatment. This study compared stage and treatment between two cohorts of postmenopausal women (55–69 vs 470 years) in a single cancer network over 6 months. A total of 378 patients were studied (470: N ¼ 167, 55–69 years: N ¼ 210). Older women presented with more advanced disease (470: metastatic/locally advanced 12%, 55–69 years: 3%, Po0.01). Those with operable cancer had a worse prognosis (Nottingham Prognostic Index (NPI) 470: median NPI 4.4, 55–69 years: 4.25, Po0.03). These stage differences were partially explained by higher screening rates in the younger cohort. Primary endocrine therapy was used in 42% of older patients compared with 3% in the younger group (Po0.001). Older women with cancers suitable for breast conservation were more likely to choose mastectomy (470: 57.5% mastectomy rate vs 55–69 years: 20.6%, Po0.01). Nodal surgery was less frequent in older patients (470: 6.7% no nodal surgery, 55–69 years: 0.5%, Po0.01) and was more likely to be inadequate (470: 10.7% o4 nodes excised, 55–69 years: 3.4%, Po0.02). In summary, older women presented with more advanced breast cancer, than younger postmenopausal women and were treated less comprehensively

Opportunities and priorities for breast surgical research

Background: The Breast Cancer Campaign Gap analysis (2013) established breast cancer research priorities without specific focus on surgical research nor the role of surgeons. The majority of breast cancer patients encounter a surgeon at diagnosis or during treatment, thus surgical involvement in design and delivery of high-quality research to improve patient care is critical. This review aims to identify opportunities and priorities for breast surgical research to complement the previous gap analysis. Methods: Research-active breast surgeons met and identified topic areas for breast surgical research which mapped to the patient pathway. These included diagnosis, neoadjuvant treatment, surgery, adjuvant therapy and special groups (e.g. risk-reducing surgery). Section leads were identified based on research interests with invited input from experts in specific areas, supported by consultation with the Association of Breast Surgery (ABS) membership and Independent Cancer Patients’ Voice (ICPV). The document was iteratively modified until participants were satisfied that key priorities for surgical research were clear. Results: Key research gaps were identified for each topic area including: (1) issues surrounding overdiagnosis and treatment; (2) optimising selection for neoadjuvant therapies and subsequent surgery; (3) reducing re-operation rates for breast conserving surgery; (4) generating evidence for the clinical and cost-effectiveness of breast reconstruction and mechanisms for evaluating novel interventions; (5) determining optimal axillary management, especially post-neoadjuvant treatment; (6) defining and standardising indications for risk-reducing surgery. Strategies for resolving these knowledge gaps are proposed. Conclusions: Surgeons are ideally placed for a central role in breast cancer research and should foster a culture of engagement and participation in research to benefit patients and the NHS. Development of infrastructure and surgical research capacity together with appropriate allocation of research funding will be needed to successfully address the key clinical and translational research gaps highlighted in this analysis within the next two decades

Bridging The Age Gap: observational cohort study of effects of chemotherapy and trastuzumab on recurrence, survival and quality of life in older women with early breast cancer.

BACKGROUND: Chemotherapy improves outcomes for high risk early breast cancer (EBC) patients but is infrequently offered to older individuals. This study determined if there are fit older patients with high-risk disease who may benefit from chemotherapy. METHODS: A multicentre, prospective, observational study was performed to determine chemotherapy (±trastuzumab) usage and survival and quality-of-life outcomes in EBC patients aged ≥70 years. Propensity score-matching adjusted for variation in baseline age, fitness and tumour stage. RESULTS: Three thousands four hundred sixteen women were recruited from 56 UK centres between 2013 and 2018. Two thousands eight hundred eleven (82%) had surgery. 1520/2811 (54%) had high-risk EBC and 2059/2811 (73%) were fit. Chemotherapy was given to 306/1100 (27.8%) fit patients with high-risk EBC. Unmatched comparison of chemotherapy versus no chemotherapy demonstrated reduced metastatic recurrence risk in high-risk patients(hazard ratio [HR] 0.36 [95% CI 0.19-0.68]) and in 541 age, stage and fitness-matched patients(adjusted HR 0.43 [95% CI 0.20-0.92]) but no benefit to overall survival (OS) or breast cancer-specific survival (BCSS) in either group. Chemotherapy improved survival in women with oestrogen receptor (ER)-negative cancer (OS: HR 0.20 [95% CI 0.08-0.49];BCSS: HR 0.12 [95% CI 0.03-0.44]).Transient negative quality-of-life impacts were observed. CONCLUSIONS: Chemotherapy was associated with reduced risk of metastatic recurrence, but survival benefits were only seen in patients with ER-negative cancer. Quality-of-life impacts were significant but transient. TRIAL REGISTRATION: ISRCTN 46099296

Bridging the age gap in breast cancer: impact of chemotherapy on quality of life in older women with early breast cancer

Introduction Older patients with early breast cancer (EBC) derive modest survival benefit from chemotherapy but have increased toxicity risk. Data on the impact of chemotherapy for EBC on quality of life in older patients are limited, but this is a key determinant of treatment acceptance. We aimed to investigate its effect on quality of life in older patients enrolled in the Bridging the Age Gap study. Materials and methods A prospective, multicentre, observational study of EBC patients ≥70 years old was conducted in 2013–2018 at 56 UK hospitals. Demographics, patient, tumour characteristics, treatments and adverse events were recorded. Quality of life was assessed using the European Organisation for Research and Treatment of Cancer Quality-of-Life Questionnaires (EORTC-QLQ) C30, BR23 and ELD 15 plus the Euroqol-5D (eq-5d) over 24 months and analysed at each time point using baseline adjusted linear regression analysis and propensity score-matching. Results Three thousand and four hundred sixteen patients were enrolled in the study; 1520 patients undergoing surgery and who had high-risk EBC were included in this analysis. 376/1520 (24.7%) received chemotherapy. At 6 months, chemotherapy had a significant negative impact in several EORTC-QLQ-C30 domains, including global health score, physical, role, social functioning, cognition, fatigue, nausea/vomiting, dyspnoea, appetite loss, diarrhoea and constipation. Similar trends were documented on other scales (EORTC-QLQ-BR23, EORTC-QLQ-ELD15 and EQ-5D-5L). Its impact was no longer significant at 18–24 months in unmatched and matched cohorts. Conclusions The negative impact of chemotherapy on quality-of-life is clinically and statistically significant at 6 months but resolves by 18 months, which is crucial to inform decision-making for older patients contemplating chemotherapy
