Examining the variation in consent in general surgery.

INTRODUCTION: Consent is a fundamental aspect of surgery and expectations around the consent process have changed following the Montgomery vs Lanarkshire Health Board (2015) court ruling. This study aimed to identify trends in litigation pertaining to consent, explore variation in how consent is practised among general surgeons and identify potential causes of this variation. METHODS: This mixed-methods study examined temporal variation in litigation rates relating to consent (between 2011 and 2020), using data obtained from National Health Service (NHS) Resolutions. Semi-structured clinician interviews were then conducted to gain qualitative data regarding how general surgeons take consent, their ideologies and their outlook on the recent legal changes. The quantitative component included a questionnaire survey aiming to explore these issues with a larger population to improve the generalisability of the findings. RESULTS: NHS Resolutions litigation data showed a significant increase in litigation pertaining to consent following the 2015 health board ruling. The interviews demonstrated considerable variation in how surgeons approach consent. This was corroborated by the survey, which illustrated considerable variation in how consent is documented when different surgeons are presented with the same case vignette. CONCLUSION: A clear increase in litigation relating to consent was seen in the post-Montgomery era, which may be due to legal precedent being established and increased awareness of these issues. Findings from this study demonstrate variability in the information patients receive. In some cases, consent practices did not adequately meet current regulations and therefore are susceptible to potential litigation. This study identifies areas for improvement in the practice of consent.

Psychosocial outcomes after varying risk management strategies in women at increased familial breast cancer risk: a mixed methods study of patient and partner outcomes.

INTRODUCTION: Female carriers of BRCA1/2 genes have an increased lifetime risk of breast cancer. Options for managing risk include imaging surveillance or risk-reducing surgery (RRS). This mixed methods study aimed to identify factors affecting risk-management decisions and the psychosocial outcomes of these decisions for high-risk women and their partners. METHODS: Semi-structured qualitative interviews were performed with women at high breast cancer risk who had faced these choices. Partners were also interviewed. Analysis used a framework approach. A bespoke questionnaire was developed to quantify and explore associations. RESULTS: A total of 32 women were interviewed. Of these, 27 had partners of whom 7 (26%) agreed to be interviewed. Four main themes arose: perception of risk and impact of increased risk; risk-management strategy decision-making; impact of risk-management strategy; support needs and partner relationship issues. The questionnaire response rate was 36/157 (23%). Decision satisfaction was high in both surveillance and RRS groups. Relationship changes were common but not universal. Common causes of distress following RRS included adverse body image changes. Both groups experienced generalised and cancer-specific anxiety. Drivers for surgery included having children, deaths of close family from breast cancer and higher levels of cancer anxiety. CONCLUSIONS: Levels of psychosocial and decision satisfaction were high for women choosing both RRS and surveillance but, for a minority, risk-reducing measures result in long-term psychosocial morbidity. Efforts to recognise women at increased risk of psychological morbidity may allow targeted support.

Non-invasive screening of breast cancer from fingertip smears-a proof of concept study.

Breast cancer is a global health issue affecting 2.3 million women per year, causing death in over 600,000. Mammography (and biopsy) is the gold standard for screening and diagnosis. Whilst effective, this test exposes individuals to radiation, has limitations to its sensitivity and specificity and may cause moderate to severe discomfort. Some women may also find this test culturally unacceptable. This proof-of-concept study, combining bottom-up proteomics with Matrix Assisted Laser Desorption Ionisation Mass Spectrometry (MALDI MS) detection, explores the potential for a non-invasive technique for the early detection of breast cancer from fingertip smears. A cohort of 15 women with either benign breast disease (n = 5), early breast cancer (n = 5) or metastatic breast cancer (n = 5) were recruited from a single UK breast unit. Fingertips smears were taken from each patient and from each of the ten digits, either at the time of diagnosis or, for metastatic patients, during active treatment. A number of statistical analyses and machine learning approaches were investigated and applied to the resulting mass spectral dataset. The highest performing predictive method, a 3-class Multilayer Perceptron neural network, yielded an accuracy score of 97.8% when categorising unseen MALDI MS spectra as either the benign, early or metastatic cancer classes. These findings support the need for further research into the use of sweat deposits (in the form of fingertip smears or fingerprints) for non-invasive screening of breast cancer.

Predicting postoperative complications and their impact on quality of life and functional status in older patients with breast cancer.

BACKGROUND: The percentage of older patients undergoing surgery for early-stage breast cancer has decreased over the past decade. This study aimed to develop a prediction model for postoperative complications to better inform patients about the benefits and risks of surgery, and to investigate the association between complications and functional status and quality of life (QoL). METHODS: Women aged at least 70 years who underwent surgery for Tis-3 N0 breast cancer were included between 2013 and 2018. The primary outcome was any postoperative complication within 30 days after surgery. Secondary outcomes included functional status and QoL during the first year after surgery, as assessed by the Groningen Activity Restriction Scale and the European Organisation for Research and Treatment of Cancer QLQ-C30 and QLQ-BR23 questionnaires. A prediction model was developed using multivariable logistic regression and validated externally using data from the British Bridging the Age Gap Study. Linear mixed models were used to assess QoL and functional status over time. RESULTS: The development and validation cohorts included 547 and 2727 women respectively. The prediction model consisted of five predictors (age, polypharmacy, BMI, and type of breast and axillary surgery) and performed well in internal (area under curve (AUC) 0.76, 95 per cent c.i. 0.72 to 0.80) and external (AUC 0.70, 0.68 to 0.72) validations. Functional status and QoL were not affected by postoperative complication after adjustment for confounders. CONCLUSION: This validated prediction model can be used to counsel older patients with breast cancer about the postoperative phase. Postoperative complications did not affect functional status nor QoL within the first year after surgery even after adjustment for predefined confounders.

Surgery remains the standard of care for the majority of older patients with breast cancer. The percentage of older patients with breast cancer receiving surgery is decreasing. The reason for this decline is unknown, but it might be due to fear of complications. To better inform patients about the benefits and risks of surgery, the aim of this study was to develop a prediction model for complications after surgery. Another important aspect, especially for older adults with breast cancer, is quality of life, functional capacity, and ability to carry out daily tasks (functional status) after therapy. This study showed that quality of life and functional status did not decline after breast surgery, irrespective of the occurrence of postoperative complications.

An app with brief behavioural support to promote physical activity after a cancer diagnosis (APPROACH): study protocol for a pilot randomised controlled trial.

BACKGROUND: There are multiple health benefits from participating in physical activity after a cancer diagnosis, but many people living with and beyond cancer (LWBC) are not meeting physical activity guidelines. App-based interventions offer a promising platform for intervention delivery. This trial aims to pilot a theory-driven, app-based intervention that promotes brisk walking among people living with and beyond cancer. The primary aim is to investigate the feasibility and acceptability of study procedures before conducting a larger randomised controlled trial (RCT). METHODS: This is an individually randomised, two-armed pilot RCT. Patients with localised or metastatic breast, prostate, or colorectal cancer, who are aged 16 years or over, will be recruited from a single hospital site in South Yorkshire in the UK. The intervention includes an app designed to encourage brisk walking (Active 10) supplemented with habit-based behavioural support in the form of two brief telephone/video calls, an information leaflet, and walking planners. The primary outcomes will be feasibility and acceptability of the study procedures. Demographic and medical characteristics will be collected at baseline, through self-report and hospital records. Secondary outcomes for the pilot (assessed at 0 and 3 months) will be accelerometer measured and self-reported physical activity, body mass index (BMI) and waist circumference, and patient-reported outcomes of quality of life, fatigue, sleep, anxiety, depression, self-efficacy, and habit strength for walking. Qualitative interviews will explore experiences of participating or reasons for declining to participate. Parameters for the intended primary outcome measure (accelerometer measured average daily minutes of brisk walking (≥ 100 steps/min)) will inform a sample size calculation for the future RCT and a preliminary economic evaluation will be conducted. DISCUSSION: This pilot study will inform the design of a larger RCT to investigate the efficacy and cost-effectiveness of this intervention in people LWBC.

Examining the barriers faced by female surgical trainees: a qualitative study.

INTRODUCTION: Today, women make up 56% of medical students, yet just 13% of surgical consultants - a number that has remained static since 2013. This qualitative study explored some of the barriers to female success in modern surgery. METHODS: Semistructured qualitative interviews were undertaken primarily with female surgical trainees to determine the barriers they face. Male trainees and training programme directors (TPDs) were also interviewed for triangulation. RESULTS: 20 interviews were performed (16 female trainees, 3 male trainees, and 1 TPD) between October 2019 and March 2020. Family pressures and becoming a mother were significant barriers for women training in surgery - a barrier that did not apply to male trainees who were fathers, often resulting in women choosing to train less than full time (LTFT). Unfortunately LTFT training presents further obstacles for female trainees. The set-up of the national training programme in surgery provides many non-gender-specific barriers, chiefly moving hospital every 6 months causing disrupted training and long commutes, disproportionately affecting females with child care responsibilities. Sexism and discrimination are still common, both from colleagues and patients. Many participants perceived inherent differences between genders in communication and methods for coping with stress. CONCLUSION: Greater gender equality in surgery may be achieved by changes in the structure and organisation of training to reduce the tension between the professional role and the predominantly female-led role of raising children. Better equality and diversity training and awareness at all levels in surgery may help to mitigate some of the conscious and unconscious bias that still exists.

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 Angiosarcoma Surveillance Study: UK national audit of management and outcomes of angiosarcoma of the breast and chest wall.

BACKGROUND: Breast angiosarcomas are rare tumours of vascular origin. Secondary angiosarcoma occurs following radiotherapy for breast cancer. Angiosarcomas have high recurrence and poor survival rates. This is concerning owing to the increasing use of adjuvant radiotherapy for the treatment of invasive breast cancer and ductal cancer in situ (DCIS), which could explain the rising incidence of angiosarcoma. Outcome data are limited and provide a poor evidence base for treatment. This paper presents a national, trainee-led, retrospective, multicentre study of a large angiosarcoma cohort. METHODS: Data for patients with a diagnosis of breast/chest wall angiosarcoma between 2000 and 2015 were collected retrospectively from 15 centres. RESULTS: The cohort included 183 patients with 34 primary and 149 secondary angiosarcomas. Median latency from breast cancer to secondary angiosarcoma was 6 years. Only 78.9 per cent of patients were discussed at a sarcoma multidisciplinary team meeting. Rates of recurrence were high with 14 of 28 (50 per cent ) recurrences in patients with primary and 80 of 124 (64.5 per cent ) in those with secondary angiosarcoma at 5 years. Many patients had multiple recurrences: total of 94 recurrences in 162 patients (58.0 per cent). Median survival was 5 (range 0-16) years for patients with primary and 5 (0-15) years for those with secondary angiosarcoma. Development of secondary angiosarcoma had a negative impact on predicted breast cancer survival, with a median 10-year PREDICT prognostic rate of 69.6 per cent, compared with 54.0 per cent in the observed cohort. CONCLUSION: A detrimental impact of secondary angiosarcoma on breast cancer survival has been demonstrated. Although not statistically significant, almost all excess deaths were attributable to angiosarcoma. The increased use of adjuvant radiotherapy to treat low-risk breast cancer and DCIS is a cause for concern and warrants further study.

Long-term outcomes of latissimus dorsi flap breast reconstructions: A single-centre observational cohort study with up to 12 years of follow up.

INTRODUCTION: The Latissimus Dorsi Myocutaneous Flap (LDMF) is used in post-mastectomy reconstruction. This study has evaluated long-term (up to 12 years) surgical- and patient-reported outcomes from LDMF procedures. METHOD: A retrospective analysis of consecutive LDMF procedures in two UK hospitals, performed between 2006 and 2016. Case notes were reviewed for indications and outcomes. Patients were sent the BREAST-QⓇ survey by post. Outcomes, including surgical adverse events, revision, and implant loss rates, were correlated with patient risk factors. RESULTS: A BREAST-Q was posted to 199/248 LDMF patients in 2018, (excluding 49 patients due to death, reduced cognitive function and incorrect coding) of whom 77 patients responded (38.7%). In 188 cases (representing 208 LDMFs), surgical outcomes were assessable. Median time since LDMF surgery was 7 years (range 2-12). Rates of acute implant loss were 9/139 (6.4%), flap necrosis 7/208 (3.4%), shoulder stiffness 4/208 (1.9%), chronic pain 24/208 (11.5%) and unplanned revision surgery 13/208 (7%). Median satisfaction levels were high with 78% of patients satisfied with treatment outcomes, 65% of patients satisfied with their breasts, 71% of patients satisfied psychosocially and 75% of patients satisfied with their chest. Receipt of radiotherapy was not associated with a higher risk of flap necrosis or capsule formation. CONCLUSION: Long-term follow-up of a large cohort of LDMF reconstruction patients show relatively low levels of adverse events and unplanned revision surgery and high patient satisfaction, which demonstrates how temporally robust the technique is. With the rise in popularity of acellular dermal matrix reconstructions, the LDMF has relatively fallen out of favour but its potential in primary and delayed reconstruction is demonstrated.

Prehabilitation in elective abdominal cancer surgery in older patients: systematic review and meta-analysis.

BACKGROUND: Prehabilitation has emerged as a strategy to prepare patients for elective abdominal cancer surgery with documented improvements in postoperative outcomes. The aim of this study was to assess the evidence for prehabilitation interventions of relevance to the older adult. METHODS: Systematic searches were conducted using MEDLINE, Web of Science, Scopus, CINAHL and PsychINFO. Studies of preoperative intervention (prehabilitation) in patients undergoing abdominal cancer surgery reporting postoperative outcomes were included. Age limits were not set as preliminary searches revealed this would be too restrictive. Articles were screened and selected based on PRISMA guidelines, and assessment of bias was performed. Qualitative, quantitative and meta-analyses of data were conducted as appropriate. RESULTS: Thirty-three studies (3962 patients) were included. Interventions included exercise, nutrition, psychological input, comprehensive geriatric assessment and optimization, smoking cessation and multimodal (two or more interventions). Nine studies purposely selected high-risk, frail or older patients. Thirty studies were at moderate or high risk of bias. Ten studies individually reported benefits in complication rates, with meta-analyses for overall complications demonstrating significant benefit: multimodal (risk difference -0·1 (95 per cent c.i. -0·18 to -0·02); P = 0·01, I2  = 18 per cent) and nutrition (risk difference -0·18 (-0·26 to -0·10); P < 0·001, I2  = 0 per cent). Seven studies reported reductions in length of hospital stay, with no differences on meta-analysis. CONCLUSION: The conclusions of this review are limited by the quality of the included studies, and the heterogeneity of interventions and outcome measures reported. Exercise, nutritional and multimodal prehabilitation may reduce morbidity after abdominal surgery, but data specific to older patients are sparse.

ANTECEDENTES: La pre-habilitación ha surgido como una estrategia para preparar a los pacientes para la cirugía electiva del cáncer abdominal con mejoras documentadas en los resultados postoperatorios. El objetivo de este estudio fue evaluar la evidencia sobre las intervenciones de pre-habilitación relevantes en adultos de edad avanzada. MÉTODOS: Se realizaron búsquedas sistemáticas utilizando MEDLINE, Web of Science, Scopus, CINAHL y PsychINFO. Registro PROSPERO: CRD42019120381. Se incluyeron estudios de intervención preoperatoria (pre-habilitación) en pacientes sometidos a cirugía oncológica abdominal que describiesen resultados postoperatorios. No se fijaron límites en la edad dado que las búsquedas preliminares revelaron que ello sería demasiado restrictivo. Los artículos fueron examinados y seleccionados en base a las guías PRISMA y se realizó una evaluación del sesgo. Se llevó a cabo un análisis cualitativo, cuantitativo y metaanálisis de los datos según fuese apropiado. RESULTADOS: Se incluyeron 33 estudios (3.962 patients). Las intervenciones incluyeron ejercicio, nutrición, intervención psicológica, evaluación geriátrica global y optimización, abandono del tabaquismo y multimodal (dos o más intervenciones). Nueve estudios seleccionaron expresamente una población de pacientes de elevado riesgo, frágiles o de edad avanzada. Treinta estudios presentaban un riesgo moderado/alto de sesgo. Diez estudios describieron de forma individual beneficios en las tasas de complicaciones con metaanálisis para las complicaciones globales demostrando un beneficio significativo: multimodal (diferencia de riesgo -0,1 (i.c. del 95% −0,18 a −0,02); P = 0,01, I2 = 18%) e intervención nutricional (diferencia de riesgo −0,18 (i.c. del 95% −0,26 a −0,10); P < 0,001, I2 = 0%). Siete estudios describieron reducciones en la duración de la estancia hospitalaria, sin diferencias en el metaanálisis. CONCLUSIÓN: Las conclusiones de esta revisión están limitadas por la calidad de los estudios incluidos, heterogeneidad de las intervenciones y descripción de las medidas de resultados. Las intervenciones de pre-habilitación de ejercicio, nutricionales y multimodales puede reducir la morbilidad tras cirugía abdominal, pero los datos concretos en pacientes de edad avanzada son escasos.

Bridging the Age Gap: a prognostic model that predicts survival and aids in primary treatment decisions for older women with oestrogen receptor-positive early breast cancer.

BACKGROUND: A prognostic model was developed and validated using cancer registry data. This underpins an online decision support tool, informing primary treatment choice for women aged 70 years or older with hormone receptor-positive early breast cancer. METHODS: Data from women diagnosed between 2002 and 2010 in the English Northern and Yorkshire and West Midlands regions were used to develop the model. Primary treatment options of surgery with adjuvant endocrine therapy or primary endocrine therapy were compared. Models predicting the hazard of breast cancer-specific mortality and hazard of other-cause mortality were combined to derive survival probabilities. The model was validated externally using data from the Eastern Cancer Registration and Information Centre. RESULTS: The model was developed using data from 23 842 women, and validated externally on a data set from 14 526 patients. The overall model calibration was good. At 2 and 5 years, predicted mortality from breast cancer and other causes differed from the observed rate by less than 1 per cent. At 5 years, there were slight overpredictions in breast cancer mortality (2629 predicted versus 2556 observed deaths; P = 0·142) and mortality from all causes (6399 versus 6320 respectively; P = 0·583). The discrepancy varied between subgroups. Model discrimination was 0·75 or above for all mortality measures. CONCLUSION: A prognostic model for older women with oestrogen receptor-positive early breast cancer was developed and validated in the present study. This forms a basis for an online decision support tool (https://agegap.shef.ac.uk/).

ANTECEDENTES: Se ha desarrollado y validado un modelo pronóstico utilizando datos del registro de cáncer. Ello ha permitido ofrecer una herramienta online para facilitar la toma de decisiones respecto a la elección del tratamiento inicial en mujeres mayores de 70 años con cáncer de mama precoz y receptores de hormonas positivos. MÉTODOS: Se incluyeron un total de 23.842 mujeres, diagnosticadas entre 2002 y 2010 en las regiones del Norte, Yorkshire y West Midlands inglesas que cumplieron con los criterios de inclusión. Se compararon dos opciones de tratamiento: cirugía primaria asociada a tratamiento endocrino adyuvante o tratamiento primario endocrino. Para estimar la probabilidad de supervivencia se combinaron modelos predictivos para el riesgo de mortalidad específica por cáncer de mama y para el riesgo de mortalidad por otras causas. Se realizó una validación externa con datos del Eastern Cancer Registration and Information Center (n = 14.526). RESULTADOS: La calibración global del modelo fue buena. A los 2 y 5 años, la mortalidad anticipada por cáncer de mama y por otras causas difería de la observada en menos del 1%. A los 5 años, hubo una ligera sobrevaloración de la predicción de mortalidad por cáncer de mama (prevista versus real: 2.629 versus 2.556, P = 0,78) y de la mortalidad por todas las causas (6.399 versus 6.320, P = 0,14). Esta discrepancia varió entre subgrupos. La capacidad discriminativa del modelo fue del 0,75 o superior para todas las medidas de mortalidad. CONCLUSIÓN: En este estudio, se desarrolló y validó un modelo pronóstico para mujeres mayores con cáncer de mama precoz positivo para receptores de estrógenos. Esta herramienta que facilita la toma de decisiones está disponible online (https://agegap.shef.ac.uk/).

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.

Adjuvant Chemotherapy for Breast Cancer in Older Women: An Analysis of Retrospective English Cancer Registration Data.

AIMS: Adjuvant chemotherapy is recommended as a treatment for women with high recurrence risk early breast cancer. Older women are less likely to receive chemotherapy than younger women. This study investigated the impact of chemotherapy on breast cancer-specific survival in women aged 70 + years using English registry data. MATERIALS AND METHODS: Cancer registration data were obtained from two English regions from 2002 to 2012 (n = 29 728). The impact of patient-level characteristics on the probability of receiving adjuvant chemotherapy was explored using logistic regression. Survival modelling was undertaken to show the effect of chemotherapy and age/health status on breast cancer-specific survival. Missing data were handled using multiple imputation. RESULTS: In total, 11 735 surgically treated early breast cancer patients were identified. Use of adjuvant chemotherapy has increased over time. Younger age at diagnosis, increased nodal involvement, tumour size and grade, oestrogen receptor-negative or human epidermal growth factor receptor 2-positive disease were all associated with increased probability of receiving chemotherapy. Chemotherapy was associated with a significant reduction in the hazard of breast cancer-specific mortality in women with high risk cancer, after adjusting for patient-level characteristics (hazard ratio 0.74, 95% confidence interval 0.67-0.81). DISCUSSION: Chemotherapy is associated with an improved breast cancer-specific survival in older women with early breast cancer at high risk of recurrence . Lower rates of chemotherapy use in older women may, therefore, contribute to inferior cancer outcomes. Decisions on potential benefits for individual patients should be made on the basis of life expectancy, treatment tolerance and patient preference.
