Bridging the age gap in breast cancer: impact of omission of breast cancer surgery in older women with oestrogen receptor-positive early breast cancer on quality-of-life outcomes.

BACKGROUND: Primary endocrine therapy may be an alternative treatment for less fit women with oestrogen receptor (ER)-positive breast cancer. This study compared quality-of-life (QoL) outcomes in older women treated with surgery or primary endocrine therapy. METHODS: This was a multicentre, prospective, observational cohort study of surgery or primary endocrine therapy in women aged over 70 years with operable breast cancer. QoL was assessed using European Organisation for Research and Treatment of cancer QoL questionnaires QLQ-C30, -BR23, and -ELD14, and the EuroQol Five Dimensions 5L score at baseline, 6 weeks, and 6, 12, 18, and 24 months. Propensity score matching was used to adjust for baseline variation in health, fitness, and tumour stage. RESULTS: The study recruited 3416 women (median age 77 (range 69-102) years) from 56 breast units. Of these, 2979 (87.2 per cent) had ER-positive breast cancer; 2354 women had surgery and 500 received primary endocrine therapy (125 were excluded from analysis due to inadequate data or non-standard therapy). Median follow-up was 52 months. The primary endocrine therapy group was older and less fit. Baseline QoL differed between the groups; the mean(s.d.) QLQ-C30 global health status score was 66.2(21.1) in patients who received primary endocrine therapy versus 77.1(17.8) among those who had surgery plus endocrine therapy. In the unmatched analysis, changes in QoL between 6 weeks and baseline were noted in several domains, but by 24 months most scores had returned to baseline levels. In the matched analysis, major surgery (mastectomy or axillary clearance) had a more pronounced adverse impact than primary endocrine therapy in several domains. CONCLUSION: Adverse effects on QoL are seen in the first few months after surgery, but by 24 months these have largely resolved. Women considering surgery should be informed of these effects.

Bridging the age gap in breast cancer: cluster randomized trial of two decision support interventions for older women with operable breast cancer on quality of life, survival, decision quality, and treatment choices.

BACKGROUND: Rates of surgery and adjuvant therapy for breast cancer vary widely between breast units. This may contribute to differences in survival. This cluster RCT evaluated the impact of decision support interventions (DESIs) for older women with breast cancer, to ascertain whether DESIs influenced quality of life, survival, decision quality, and treatment choice. METHODS: A multicentre cluster RCT compared the use of two DESIs against usual care in treatment decision-making in older women (aged at least ≥70 years) with breast cancer. Each DESI comprised an online algorithm, booklet, and brief decision aid to inform choices between surgery plus adjuvant endocrine therapy versus primary endocrine therapy, and adjuvant chemotherapy versus no chemotherapy. The primary outcome was quality of life. Secondary outcomes included decision quality measures, survival, and treatment choice. RESULTS: A total of 46 breast units were randomized (21 intervention, 25 usual care), recruiting 1339 women (670 intervention, 669 usual care). There was no significant difference in global quality of life at 6 months after the baseline assessment on intention-to-treat analysis (difference -0.20, 95 per cent confidence interval (C.I.) -2.69 to 2.29; P = 0.900). In women offered a choice of primary endocrine therapy versus surgery plus endocrine therapy, knowledge about treatments was greater in the intervention arm (94 versus 74 per cent; P = 0.003). Treatment choice was altered, with a primary endocrine therapy rate among women with oestrogen receptor-positive disease of 21.0 per cent in the intervention versus 15.4 per cent in usual-care sites (difference 5.5 (95 per cent C.I. 1.1 to 10.0) per cent; P = 0.029). The chemotherapy rate was 10.3 per cent at intervention versus 14.8 per cent at usual-care sites (difference -4.5 (C.I. -8.0 to 0) per cent; P = 0.013). Survival was similar in both arms. CONCLUSION: The use of DESIs in older women increases knowledge of breast cancer treatment options, facilitates shared decision-making, and alters treatment selection.

Breast cancer surgery in older women: outcomes of the Bridging Age Gap in Breast Cancer study.

BACKGROUND: Breast cancer surgery in older women is variable and sometimes non-standard owing to concerns about morbidity. Bridging the Age Gap in Breast Cancer is a prospective multicentre cohort study aiming to determine factors influencing treatment selection and outcomes from surgery for older patients with breast cancer. METHODS: Women aged at least 70 years with operable breast cancer were recruited from 57 UK breast units between 2013 and 2018. Associations between patient and tumour characteristics and type of surgery in the breast and axilla were evaluated using univariable and multivariable analyses. Oncological outcomes, adverse events and quality-of-life (QoL) outcomes were monitored for 2 years. RESULTS: Among 3375 women recruited, surgery was performed in 2816 patients, of whom 24 with inadequate data were excluded. Sixty-two women had bilateral tumours, giving a total of 2854 surgical events. Median age was 76 (range 70-95) years. Breast surgery comprised mastectomy in 1138 and breast-conserving surgery in 1716 procedures. Axillary surgery comprised axillary lymph node dissection in 575 and sentinel node biopsy in 2203; 76 had no axillary surgery. Age, frailty, dementia and co-morbidities were predictors of mastectomy (multivariable odds ratio (OR) for age 1·06, 95 per cent c.i. 1·05 to 1·08). Age, frailty and co-morbidity were significant predictors of no axillary surgery (OR for age 0·91, 0·87 to 0·96). The rate of adverse events was moderate (551 of 2854, 19·3 per cent), with no 30-day mortality. Long-term QoL and functional independence were adversely affected by surgery. CONCLUSION: Breast cancer surgery is safe in women aged 70 years or more, with serious adverse events being rare and no mortality. Age, ill health and frailty all influence surgical decision-making. Surgery has a negative impact on QoL and independence, which must be considered when counselling patients about choices.

ANTECEDENTES: La cirugía del cáncer de mama en mujeres mayores es variable y, a veces, no estandarizada debido a las reservas que origina la morbilidad quirúrgica. Bridging the Age Gap in Breast Cancer es un estudio de cohortes, prospectivo, multicéntrico cuyo objetivo fue determinar los factores que influyen en la selección del tratamiento y en los resultados de la cirugía en pacientes mayores con cáncer de mama. MÉTODOS: Se reclutaron mujeres de > 70 años de edad con cáncer de mama operable atendidas en 56 unidades de mama del Reino Unido entre 2013-2018. Los datos sobre las características de la paciente y del tumor se correlacionaron con el tipo de cirugía en la mama y en la axila mediante análisis univariable y multivariable. Se controlaron los resultados oncológicos, los eventos adversos y los resultados en cuanto a la calidad de vida durante 2 años. RESULTADOS: De 3.375 mujeres reclutadas, se realizó una intervención quirúrgica en 2.816 pacientes. Hubo 62 tumores bilaterales, por lo que se analizan 2.854 procedimientos. La mediana de edad fue de 76 años (rango 70-95). En 1.138 pacientes se realizó una mastectomía y en 1.798 cirugía conservadora de la mama. En cuanto a la cirugía de la axila, en 575 pacientes se realizó una linfadenectomía, en 2.203 una biopsia de ganglio centinela y en 76 no se realizó ningún procedimiento. Los factores predictores de mastectomía fueron la edad, la fragilidad, la demencia y las comorbilidades (riesgo relativo, RR 1,06; i.c. del 95% 1,05-1,08), mientras que para la cirugía axilar los factores predictores fueron la fragilidad y las comorbilidades (RR 0,91; i.c. del 95% 0,87-0,96). La tasa de efectos adversos fue moderada (551/2854; 19,3%), sin mortalidad a los 30 días. La calidad de vida a largo plazo y la independencia funcional se vieron negativamente afectadas por la cirugía. CONCLUSIÓN: La cirugía de cáncer de mama es segura, con escasos efectos adversos graves y sin mortalidad. La edad, las comorbilidades y la fragilidad tienen impacto en la toma de decisiones quirúrgicas. La cirugía tiene una repercusión negativa en la calidad de vida e independencia funcional, hechos que deben ser tenidos en cuenta al aconsejar a las pacientes sobre las opciones terapéuticas.

Patterns of axillary staging and management in clinically node positive breast cancer patients treated with neoadjuvant systemic therapy: Results of a survey amongst breast cancer specialists.

INTRODUCTION: Various options for axillary staging after neoadjuvant systemic therapy (NST) are available for breast cancer patients with a clinically positive axillary node (cN+). This survey assessed current practices amongst breast cancer specialists. MATERIALS AND METHODS: A survey was performed amongst members of the European Society of Surgical Oncology and two UK-based Associations: the Association of Breast Surgery and the British Association of Surgical Oncology. The survey included 3 parts: 1. general information, 2. diagnostic work-up and 3. axillary staging after NST. RESULTS: A total of 310 responses were collected: parts 1, 2 and 3 were fully completed by 282 (91%), 270 (87.1%) and 225 (72.6%) respondents respectively. After NST, 153/267 (57.3%) respondents currently perform ALND routinely and 114 (42.7%) respondents perform less invasive restaging of the axilla with possible omission of ALND. In the latter group, 85% does and 15% does not use nodal response seen on imaging to guide the axillary restaging procedure. Regarding respondents that do use imaging: 95% would perform a less invasive staging procedure in case of complete nodal response on imaging (63% sentinel lymph node biopsy (SLNB), excision of a previously marked positive node with SLNB (21%) and without SLNB (11%)). In case of no nodal response on imaging 77% would perform ALND. CONCLUSION: Current axillary staging and management practices in cN + patients after NST vary widely. To determine optimal axillary staging and management in terms of quality of life and oncologic safety, breast specialists are encouraged to include patients in clinical trials/prospective registries.

European Society of Surgical Oncology's strategy for clinical research: Paving the way for a culture of research in cancer surgery.

As part of its mission to promote the best surgical care for cancer patients, the European Society of Surgical Oncology (ESSO) has been developing multiple programmes for clinical research along with its educational portfolio. This position paper describes the different research activities of the Society over the past decade and an action plan for the upcoming five years to lead innovative and high quality surgical oncology research. ESSO proposes to consider pragmatic research methodologies as a complement to randomised clinical trials (RCT), advocates for increased funding and operational support in conducting research and aims to enable young surgeons to be active in research and establish partnerships for translational research activities.

Variability in breast cancer surgery training across Europe: An ESSO-EUSOMA international survey.

BACKGROUND: At present there is a lack of standardization of training in breast cancer surgery across Europe. The aim of this survey was to assess current practice in Europe regarding training in breast cancer (BC) surgery. MATERIAL AND METHODS: General surgeons, surgical oncologists, gynecologist, and plastic surgeons in Europe were invited to participate in this bespoke survey including 19 questions. RESULTS: The survey was sent to 3.000 surgical oncologists across Europe. A total of 671 physicians (387 general surgeons, 152 gynecologists, 126 surgical oncologist, 31 plastic surgeons) answered the survey (23% response rate). Four hundred and sixty-eight physicians devoted between 50% -100% of their job to treating breast cancer. 45% worked in a community/University hospital within a dedicated Breast Unit. Specific additional breast surgery training was not universal: 20% had undertaken an accredited breast fellowship, 30% in a Breast Unit as a trainee, 21% had done additional courses, masters or diploma and 8% had not done any additional training. The majority (61%) of respondents worked in Units treating >150 BC cases per year, while 26% of the responders treat >120 new primary cases per year, and 23% less than 50 new cases a year. Multivariate analysis showed that breast surgeons working in a Breast Unit and treating more than 50 cases/year significantly performed oncoplastic procedures. CONCLUSION: There is a great variability in breast cancer surgery training in Europe. It is imperative to develop quality standards for breast cancer surgery training to ensure that patients get standardized and certified surgical management regardless of the country in which they are treated.

Multidisciplinary development of the Geriatric Core Dataset for clinical research in older patients with cancer: A French initiative with international survey.

BACKGROUND: To define a core set of geriatric data to be methodically collected in clinical cancer trials of older adults, enabling comparison across trials. PATIENTS AND METHODS: Following a consensus approach, a panel of 14 geriatricians from oncology clinics identified seven domains of importance in geriatric assessment. Based on the international recommendations, geriatricians selected the mostly commonly used tools/items for geriatric assessment by domain (January-October 2015). The Geriatric Core Dataset (G-CODE) was progressively developed according to RAND appropriateness ratings and feedback during three successive Delphi rounds (July-September 2016). The face validity of the G-CODE was assessed with two large panels of health professionals (55 national and 42 international experts) involved both in clinical practice and cancer trials (March-September 2017). RESULTS AND DISCUSSION: After the last Delphi round, the tools/items proposed for the G-CODE were the following: (1) social assessment: living alone or support requested to stay at home; (2) functional autonomy: Activities of Daily Living (ADL) questionnaire and short instrumental ADL questionnaire; (3) mobility: Timed Up and Go test; (4) nutrition: weight loss during the past 6 months and body mass index; (5) cognition: Mini-Cog test; (6) mood: mini-Geriatric Depression Scale and (7) comorbidity: updated Charlson Comorbidity Index. More than 70% of national experts (42 from 20 cities) and international experts (31 from 13 countries) participated. National and international surveys showed good acceptability of the G-CODE. Specific points discussed included age-year cut-off, threshold of each tool/item and information about social support, but no additional item was proposed. CONCLUSION: We achieved formal consensus on a set of geriatric data to be collected in cancer trials of older patients. The dissemination and prospective use of the G-CODE is needed to assess its utility.

Global Curriculum in Research Literacy for the Surgical Oncologist.

BACKGROUND: The ability to provide optimal care to cancer patients depends on awareness of current evidence-based practices emanating from research or involvement in research where circumstances permit. The significant global variations in cancer-related research activity and its correlation to cancer-specific outcomes may have an influence on the care provided to cancer patients and their outcomes. The aim of this project is to develop a global curriculum in research literacy for the surgical oncologist. MATERIALS AND METHODS: The leadership of the Society of Surgical Oncology and European Society of Surgical Oncology convened a global curriculum committee to develop a global curriculum in research literacy for the Surgical Oncologist. RESULTS: A global curriculum in research literacy is developed to incorporate the required domains considered to be essential to interpret the published research or become involved in research activity where circumstances permit. The purpose of this curriculum is to promote research literacy for the surgical oncologist, wherever they are based. It does not mandate direct research participation which may not be feasible due to restrictions within the local health-care delivery environment, socio-economic priorities and the educational environment of the individual institution where they work. CONCLUSIONS: A global curriculum in research literacy is proposed which may promote research literacy or encourage involvement in research activity where circumstances permit. It is hoped that this will enhance cancer-related research activity, promote awareness of optimal evidence-based practices and improve outcomes for cancer patients globally.

Global Variations in the Level of Cancer-Related Research Activity and Correlation to Cancer-Specific Mortality: Proposal for a Global Curriculum.

INTRODUCTION: The aim of this study was to analyze global variations in the level of cancer-related research activity and correlate this with cancer-specific mortality. METHODS: The SCOPUS database was explored to obtain data relating to the number of cancer-related publications per country. Cancer-specific mortality rates were obtained from the World Health Organization. Global variations in the level of scholarly activity were analyzed and correlated with variations in cancer-specific mortality. RESULTS: Data for 142 countries were obtained and significant variations in the level of research activity was noted. The level of research activity increased with rising socio-economic status. The United States was the most prolific country with 222,300 publications followed by Japan and Germany. Several countries in different regions of the world had a low level of research activity. An inverse relationship between the level of research activity and cancer-specific mortality was noted. This relationship persisted even in countries with a low level of research activity. The socioeconomic status of a nation and geographic location (continent) had a mixed influence with an overall apparent correlation with cancer-related research activity. CONCLUSION: This study demonstrates significant global variation in the level of cancer-related research activity and a correlation with cancer-specific mortality. The presence of a minimum set of standards for research literacy, as proposed by the European Society of Surgical Oncology and the Society of Surgical Oncology may contribute to enhanced research activity and improve outcomes for cancer patients worldwide.

Time trends (2006-2015) of quality indicators in EUSOMA-certified breast centres.

AIM OF THE STUDY: The European Society of Breast Cancer Specialists (EUSOMA) has fostered a voluntary certification process for breast centres to establish minimum standards and ensure specialist multidisciplinary care. Prospectively collected anonymous information on primary breast cancer cases diagnosed and treated in the units is transferred annually to a central EUSOMA data warehouse for continuous monitoring of quality indicators (QIs) to improve quality of care. Units have to comply with the EUSOMA Breast Centre guidelines and are audited by peers. The database was started in 2006 and includes over 110,000 cancers from breast centres located in Germany, Switzerland, Belgium, Austria, The Netherlands, Spain, Portugal and Italy. The aim of the present study is assessing time trends of QIs in EUSOMA-certified breast centres over the decade 2006-2015. MATERIALS AND METHODS: Previously defined QIs were calculated for 22 EUSOMA-certified breast centres (46122 patients) during 2006-2015. RESULTS: On the average of all units, the minimum standard of care was achieved in 8 of 13 main EUSOMA QIs in 2006 and in all in 2015. All QIs, except removal of at least 10 lymph nodes at axillary clearance and oestrogen receptor-negative tumours (T > 1 cm or N+) receiving adjuvant chemotherapy, improved significantly in this period. The desirable target was reached for two QIs in 2006 and for 7 of 13 QIs in 2015. CONCLUSION: The EUSOMA model of audit and monitoring QIs functions well in different European health systems and results in better performance of QIs over the last decade. QIs should be evaluated and adapted on a regular basis, as guidelines change over time.

Human papillomavirus 9-valent vaccine for cancer prevention: a systematic review of the available evidence.

In 2014, the Food and Drug Administration approved a new human papillomavirus 9-valent vaccine (9vHPV), targeting nine HPV types: HPV types 6, 11, 16, and 18, which are also targeted by the quadrivalent HPV vaccine (qHPV), plus five additional high cancer risk HPV types (HPV types 31, 33, 45, 52, and 58). The aim of the current study was to systematically retrieve, qualitatively and quantitatively pool, as well as critically appraise all available evidence on 9vHPV from randomized controlled trials (RCTs). We conducted a systematic review of the literature on 9vHPV efficacy, immunogenicity and safety, as well as a systematic search of registered, completed, and ongoing RCTs. We retrieved and screened 227 records for eligibility. A total of 10 publications reported on RCTs' results on 9vHPV and were included in the review. Sixteen RCTs on 9vHPV have been registered on RCT registries. There is evidence that 9vHPV generated a response to HPV types 6, 11, 16 and 18 that was non-inferior to qHPV. Vaccine efficacy against five additional HPV type-related diseases was directly assessed on females aged 16-26 years (risk reduction against high-grade cervical, vulvar or vaginal disease = 96·7%, 95% CI 80·9%-99·8%). Bridging efficacy was demonstrated for males and females aged 9-15 years and males aged 16-26 years (the lower bound of the 95% CIs of both the geometric mean titer ratio and difference in seroconversion rates meeting the criteria for non-inferiority for all HPV types). Overall, 9vHPV has been proved to be safe and well tolerated. Other RCTs addressed: 9vHPV co-administration with other vaccines, 9vHPV administration in subjects that previously received qHPV and 9vHPV efficacy in regimens containing fewer than three doses. The inclusion of additional HPV types in 9vHPV offers great potential to expand protection against HPV infection. However, the impact of 9vHPV on reducing the global burden of HPV-related disease will greatly depend on vaccine uptake, coverage, availability, and affordability.

What influences healthcare professionals' treatment preferences for older women with operable breast cancer? An application of the discrete choice experiment.

INTRODUCTION: Primary endocrine therapy (PET) is used variably in the UK as an alternative to surgery for older women with operable breast cancer. Guidelines state that only patients with "significant comorbidity" or "reduced life expectancy" should be treated this way and age should not be a factor. METHODS: A Discrete Choice Experiment (DCE) was used to determine the impact of key variables (patient age, comorbidity, cognition, functional status, cancer stage, cancer biology) on healthcare professionals' (HCP) treatment preferences for operable breast cancer among older women. Multinomial logistic regression was used to identify associations. RESULTS: 40% (258/641) of questionnaires were returned. Five variables (age, co-morbidity, cognition, functional status and cancer size) independently demonstrated a significant association with treatment preference (p < 0.05). Functional status was omitted from the multivariable model due to collinearity, with all other variables correlating with a preference for operative treatment over no preference (p < 0.05). Only co-morbidity, cognition and cancer size correlated with a preference for PET over no preference (p < 0.05). CONCLUSION: The majority of respondents selected treatment in accordance with current guidelines, however in some scenarios, opinion was divided, and age did appear to be an independent factor that HCPs considered when making a treatment decision in this population.

Global curriculum in surgical oncology.

BACKGROUND: The significant global variations in surgical oncology training paradigms can have a detrimental effect on tackling the rising global cancer burden. While some variations in training are essential to account for the differences in types of cancer and biology, the fundamental principles of providing care to a cancer patient remain the same. The development of a global curriculum in surgical oncology with incorporated essential standards could be very useful in building an adequately trained surgical oncology workforce, which in turn could help in tackling the rising global cancer burden. MATERIALS AND METHODS: The leaders of the Society of Surgical Oncology and European Society of Surgical Oncology convened a global curriculum committee to develop a global curriculum in surgical oncology. RESULTS: A global curriculum in surgical oncology was developed to incorporate the required domains considered to be essential in training a surgical oncologist. The curriculum was constructed in a modular fashion to permit flexibility to suit the needs of the different regions of the world. Similarly, recognizing the various sociocultural, financial and cultural influences across the world, the proposed curriculum is aspirational and not mandatory in intent. CONCLUSIONS: A global curriculum was developed which may be considered as a foundational scaffolding for training surgical oncologists worldwide. It is envisioned that this initial global curriculum will provide a flexible and modular scaffolding that can be tailored by individual countries or regions to train surgical oncologists in a way that is appropriate for practice in their local environment.

Poor nutritional status is associated with other geriatric domain impairments and adverse postoperative outcomes in onco-geriatric surgical patients - A multicentre cohort study.

BACKGROUND: Nutritional status (NS), though frequently affected in onco-geriatric patients, is no standard part of a geriatric assessment. The aim of this study was to analyse the association between a preoperatively impaired NS and geriatric domain impairments and adverse postoperative outcomes in onco-geriatric surgical patients. METHODS: 309 patients ≥70 years undergoing surgery for solid tumours were prospectively recruited. Nine screening tools were preoperatively administered as part of a geriatric assessment. NS was based on BMI, weight loss and food intake. Odds ratio's (OR) and 95% confidence intervals (95% CI) were estimated using logistic regression analysis. The occurrence of 30-day adverse postoperative outcomes was recorded. RESULTS: At a median age of 76 years, 107 patients (34.6%) had an impaired NS. Decreased performance status and depression were associated with an impaired NS, when adjusted for tumour characteristics and comorbidities (ORPS>1 3.46; 95% CI 1.56-7.67. ORGDS>5 2.11; 95% CI 1.05-4.26). An impaired NS was an independent predictor for major complications (OR 3.3; 95% CI 1.6-6.8). Ten out of 11 patients who deceased had an impaired NS. CONCLUSION: An impaired NS is prevalent in onco-geriatric patients considered to be fit for surgery. It is associated with decreased performance status and depression. An impaired NS is a predictor for adverse postoperative outcomes. NS should be incorporated in a geriatric assessment.

Variations in training of surgical oncologists: Proposal for a global curriculum.

BACKGROUND: The global cancer burden is predicted to rise significantly over the next few decades. While there are several barriers to providing optimal cancer care on the global stage, some are related to the absence of an adequately trained workforce. This could be attributed in part to the significant global variations in the training of surgical oncology professionals. There are currently no published data mapping the training pathways for surgical oncologists for all countries in the world. The aims of this descriptive article are to report on the training paradigms in surgical oncology for all countries in the world, and to correlate the influence of economic standing on these training paradigms. MATERIALS AND METHODS: The training paradigms for all countries in the world were analyzed and categorized on the basis of the six World Health Organization geographic regions and economic standing stratified by the Human Development Index. RESULTS: Data on the training paradigms were obtained for 174 countries from a total of 211 (82%). We noted extremely significant and concerning variations in the length, availability and structure of training paradigms depending on the geographic region and economic standing. CONCLUSIONS: The results of our study demonstrated significant global variations in the training paradigms of surgical oncologists. These variations call for a global curriculum which has been developed by the Society of Surgical Oncology and the European Society of Surgical Oncology. It is hoped that this curriculum will serve a role in streamlining education to tackle the rising global cancer burden.
