The Effectiveness of an Upper Limb Rehabilitation Program on Quality of Life in Breast Cancer Patients after Mastectomy: A Randomized Controlled Trial.

OBJECTIVE: This study aims to investigate the effectiveness of an upper limb rehabilitation program on the quality of life in patients who had been first diagnosed breast cancer and subsequently underwent mastectomy. DATA SOURCES: This randomized controlled trial enrolled 48 breast cancer patients who underwent mastectomy at a medical center in Taiwan. The patients were randomly assigned to either the intervention group (n = 24) or control group (n = 24). The patients in the intervention group participated in a 12-week upper limb rehabilitation program involving face-to-face upper limb rehabilitation education and once-a month monitoring of their upper extremity activity. The control group received standard nursing care. Quality of life was assessed through EORTC QLQ-C30 and QLQ-BR 23 questionnaires at baseline and weeks 4, 8, and 12 after enrollment. RESULTS: Both the intervention and control groups had significantly improved their levels of functioning, symptoms, and quality of life from baseline to week 12 after enrollment. The intervention group showed greater improvements in functioning and symptom levels after the intervention compared to the control group; however, no statistically significant differences were found. Additionally, the levels of global health status/quality of life in both groups gradually increased from baseline to week 12 CONCLUSION: An upper limb rehabilitation program is effective in improving the functioning and symptoms of breast cancer patients who have undergone mastectomy. IMPLICATIONS FOR NURSING PRACTICE: Patients are encouraged to undergo upper limb rehabilitation in order to improve their functioning, symptoms and quality of life.

Return of the Flap; The Empire State Mandate: A Multi-decade Multi-institutional Analysis of the 2010 New York State Legislature's Impact on Postmastectomy Immediate Flap-Based Reconstruction.

PURPOSE: Immediate postmastectomy breast reconstruction plays an integral role in patient care because of its psychosocial benefits. New York State (NYS) passed the 2010 Breast Cancer Provider Discussion Law with the aim of increasing patient awareness of reconstructive options through mandating plastic surgery referral at the time of cancer diagnosis. Short-term analysis of the years surrounding implementation suggests the law increased access to reconstruction, especially for certain minority groups. However, given the continued presence of disparities in access to autologous reconstruction, we aimed to investigate the longitudinal effects of the bill on access to autologous reconstruction along various sociodemographic cohorts. METHODS: Retrospective review identified demographic, socioeconomic, and clinical data for patients undergoing mastectomy with immediate reconstruction at Weill Cornell Medicine and Columbia University Irving Medical Center from 2002 to 2019. Primary outcome was receiving implant or autologous-based reconstruction. Subgroup analysis was based on sociodemographic factors. Multivariate logistic regression identified predictors of autologous reconstruction. Interrupted time series modeling analyzed differences in reconstructive trends for subgroups before and after the 2011 implementation of the NYS law. RESULTS: We included 3178 patients; 2418 (76.1%) and 760 (23.9%) patients underwent implant and autologous-based reconstruction, respectively. Multivariate analysis indicated that race, Hispanic status, and income were not predictors of autologous reconstruction. Interrupted time series showed that with each year leading up to 2011 implementation, patients were 19% less likely to receive autologous-based reconstruction. Following implementation, there was a 34% increase in the odds of receiving autologous-based reconstruction with each passing year. Following implementation, Asian American and Pacific Islander patients experienced a 55% greater increase in the rate of flap reconstruction than White patients. Following implementation, the highest-income quartile experienced a 26% greater increase in the rate of autologous-based reconstruction compared with the lowest-income quartile. After implementation, Hispanic patients experienced a 30% greater decrease in the rate of autologous-based reconstruction compared with non-Hispanic patients. CONCLUSIONS: Our data indicate the long-term efficacy of the NYS Breast Cancer Provider Discussion Law in increasing access to autologous-based reconstruction, especially for certain minority groups. These findings underscore the importance of this bill and encourage its adoption into other states.

Interventions for work participation of unemployed or work-disabled cancer survivors: a systematic review.

Background: Supporting unemployed or work-disabled cancer survivors in their work participation can have extensive individual and societal benefits. We aimed to identify and summarise interventions for work participation of unemployed or work-disabled cancer survivors.Methods: Five databases (Medline, Embase, PsycINFO, CINAHL and Cochrane Library) were systematically searched for quantitative studies on interventions aimed at enhancing work participation of unemployed or work-disabled cancer survivors. Work participation refers to participation in the workforce, fulfilling one's work role. Manual and automatic screening (with ASReview software) were performed on titles and abstracts, followed by manual full-text screening. Data were extracted regarding study, patient and intervention characteristics, and work participation outcomes. Risk of bias (RoB) was assessed using the Cochrane RoB2 and QUIPS tools.Results: We identified 10,771 articles, of which we included two randomised controlled trials (RCTs), of which one feasibility RCT, and three cohort studies. In total, 1862 cancer survivors were included, with predominantly breast cancer. Work participation was mainly measured as time to return to work (RTW) and RTW rate. Interventions included components of coaching (e.g., psychological or rehabilitation), training (e.g., building confidence and managing fatigue) and self-management. Two RCTs with unclear RoB did not show an effect of multicomponent interventions compared to care as usual. One cohort study found a significant effect of a psycho-educational intervention on RTW rates, with moderate RoB. The other two cohort studies, with moderate RoB, reported significant associations between components including job search and placement assistance, and work participation.Discussion: Only few interventions aimed at enhancing work participation of unemployed or work-disabled cancer survivors, have been evaluated. In two cohort studies, promising components for future multicomponent interventions were identified. However, findings suggest that more evidence is necessary on such multicomponent interventions, in which elements explicitly directed at work and including the workplace should be included.

Satisfaction With Information Predicts Satisfaction With Outcome and Surgeon in Black and Hispanic Patients Undergoing Breast Reconstruction.

BACKGROUND: Racial disparities in American healthcare contribute to worse outcomes among minority patients. Minority patients undergoing breast reconstruction are more likely to report dissatisfaction with their reconstruction process as compared with White patients, yet there is limited research exploring contributory factors. This study investigates which process-of-care, clinical, and surgical variables are most strongly correlated with Black and Hispanic patients' reported satisfaction. METHODS: A retrospective review of all patients who underwent postmastectomy breast reconstruction at a single academic center from 2015 to 2021 was performed. Patients were included for analysis if they identified as Black or Hispanic and completed preoperative, less than 1-year postoperative, and 1- to 3-year postoperative BREAST-Q surveys. At both postoperative time points, the association between satisfaction with outcome and surgeon and selected independent variables was determined using regression analysis. RESULTS: One hundred eighteen Black and Hispanic patients were included for analysis, with average age 49.59 ± 9.51 years and body mass index 30.11 ± 5.00 kg/m 2 . In the multivariate model for predicting satisfaction with outcome, only satisfaction with preoperative information ( P < 0.001) was a statistically significant predictor during early and late postoperative evaluations. For predicting satisfaction with surgeon, satisfaction with information ( P < 0.001) remained a significant predictor in the early and late postoperative evaluations, with lower body mass index as an additionally significant predictor during the late postoperative period. CONCLUSIONS: Patient satisfaction with preoperative information received is the single most significant factor associated with Black and Hispanic patient satisfaction with outcome and plastic surgeon. This finding encourages further research on effective and culturally inclusive information delivery so as to both improve patient satisfaction and reduce healthcare disparities.

Systematic review of aquatic therapeutic exercise efficacy in breast cancer survivors.

PURPOSE: The aim of this review is to establish the efficacy of aquatic therapeutic exercise in female breast cancer survivors for improving fatigue, pain, lymphedema, and quality of life. METHODS: A systematic literature review was conducted in PubMed, Web of Science, and Cochrane Library databases for articles published in the last 10 years. The review focuses on aquatic exercise-based rehabilitation in female breast cancer survivors, according to the PRISMA statement and using the PEDRO and Jadad scales. RESULTS: Ten randomized controlled trials with 606 participants were included. Two studies showed aquatic therapeutic exercise to be effective in reducing fatigue, three in reducing pain, and four in improving quality of life after intervention. Three of five studies obtained significant immediate changes in lymphedema volume, although this improvement was only maintained at 3 months in a single study. The methodological quality of all the studies was ≥ 7 on the PEDro scale and ≥ 3 on the Jadad scale. CONCLUSION: Aquatic therapeutic exercise is an effective strategy for improving fatigue, pain, and quality of life in breast cancer survivors, although the effects on lymphedema remain uncertain. Participants showed high adherence to treatment and no adverse effects after intervention were reported.

¿Son los colgajos toracoabdominales una herramienta útil en el tratamiento del carcinoma de mama avanzado? / Are thoracoabdominal flaps an effective tool in the treatment of advanced breast cancer?

A pesar de los avances en el tratamiento del cáncer de mama existen casos en los que la enfermedad se presenta en estadios avanzados y precisa tratamientos quirúrgicos agresivos que originan grandes defectos en la pared torácica. Dentro de las diferentes técnicas comprendidas en la cirugía oncoplástica, los colgajos toracoabdominales, incluidos en el grupo de colgajos de rotación, se han postulado como una técnica atractiva para cubrir los amplios defectos que resultan de estas cirugías tan extensas, con el fin de comenzar precozmente el tratamiento adyuvante y mejorar la supervivencia sin aumentar la morbilidad. Es importante establecer una correcta indicación y el exhaustivo conocimiento de la anatomía con el objetivo de conseguir un cierre simple del defecto con una buena cobertura cutánea. (AU)

Despite advances in the treatment of breast cancer, there are cases in which the disease occurs in advanced stages and requires aggressive surgical treatments that cause large defects in the chest wall. Within the different techniques included in oncoplastic surgery, the thoracoabdominal flaps, included in the group of rotation flaps, have been postulated as an attractive technique to cover the wide defects resulting from these extensive surgeries, in order to start adjuvant treatment earlier and improve survival without increasing morbidity. It is important to establish a correct indication and an exhaustive knowledge of the anatomy in order to achieve a simple closure of the defect with good skin coverage. (AU)

Predictors and effectiveness of different biopsy techniques in spotting invasion in the clinically diagnosed breast ductal carcinoma in situ / Factores predictivos y efectividad de diferentes técnicas de biopsia en la detección de focos infiltrantes en carcinomas in situ diagnosticados clínicamente

Objectives: To study the management of patients with ductal carcinoma in situ (DCIS) and detect the predictors of recurrence and of missing an invasive component in the preoperative biopsy, aiming at guiding tailored treatment of these cases.Materials and methods: A total of 123 cases of DCIS, pure/with invasion, were retrieved from the database of a tertiary cancer hospital in the period from February 2007 to February 2018. Clinical, radiologic & pathologic characteristics and its impact on the surgical management were analyzed.Results: The mean age of the patients was 50.5±12.4 years. The commonest presentation was a palpable mass in 82.9% of the cases. Conservative breast surgery was successfully performed in 15 cases and mastectomy in 108 cases. Recurrence was reported in 11 cases. The underestimation rate in core needle biopsy was 48.9% missing invasive component within diagnosed malignant lesions and 19.6% missing the diagnosis of malignancy. On the other hand, overtreatment was noted as regard surgical procedure and adjuvant therapies.Conclusions: Mastectomy still the most common surgical treatment of DCIS and unfortunately sentinel lymph node biopsy is still underused. Underestimation of invasive component can occur in at least 1/4 of the patients, complexing the treatment plan. Overtreatment with axillary surgery, chemotherapy or radiotherapy needs governance. (AU)

Objetivos: Estudiar el manejo de pacientes con carcinoma ductal in situ (CDIS) y detectar los predictores de recaída y de ausencia de un componente invasivo en la biopsia preoperatoria, con el objetivo de orientar el tratamiento a medida de estos casos.Materiales y métodos: Se recuperó un total de 123 casos de CDIS, puro/con invasión de la base de datos de un hospital de cáncer terciario en el período de febrero de 2007 a febrero de 2018. Se analizaron las características clínicas, radiológicas y patológicas, así como su impacto en el manejo quirúrgico.Resultados: La edad media fue de 50,5 ± 12,4 años. La presentación más común fue masa palpable en el 82,9% de los casos. Se realizó cirugía de mama conservadora con éxito en 15 casos y mastectomía en 108 casos. Se informó de recaída en 11 casos. La tasa de subestimación en la biopsia con aguja fue de 48,9% sin componente invasivo en lesiones malignas diagnosticadas y 19,6% sin diagnóstico de malignidad. Por otra parte, se observó un exceso de tratamiento con relación al procedimiento quirúrgico y las terapias adyuvantes.Conclusiones: La mastectomía sigue siendo el tratamiento quirúrgico más común del CDIS y desafortunadamente no se utiliza aún la biopsia de ganglio linfático centinela. La subestimación del componente invasivo puede ocurrir en al menos el 25% de los pacientes, complejizando el plan de tratamiento. Debe gestionarse el sobretratamiento con cirugía axilar, quimioterapia o radioterapia. (AU)

Introducción: La pandemia por COVID-19ha tenido un importante impacto en todos los ámbitos; uno de los más afectados ha sido la sanidad. La pandemia ha supuesto una reorganización de los recursos tanto humanos como materiales, dada la saturación del sistema sanitario. Como especialistas en el cáncer de mama hemos tenido que adaptarnos a esta situación, reorganizando y ajustando los cuidados a los medios profesionales e infraestructuras de los que disponíamos en cada momento. La incidencia variable a lo largo del año ha permitido desarrollar una actividad normalizada en algunas ocasiones. Nos proponemos describir nuestra experiencia en la cirugía del cáncer de mama durante este año de pandemia de COVID-19.Material y métodos: Estudio observacional retrospectivo de pacientes intervenidas de neoplasia de mama desde el 14 de marzo de 2020 hasta el 14 de marzo de 2021.Resultados: Se han intervenido 138 neoplasias de mama en 136 mujeres.La edad media fue de 62 años (36-88). Hubo 86 pacientes (63,2%) en régimen de cirugía mayor ambulatoria y 50 pacientes (36,8%) con ingreso. El tiempo medio desde el diagnóstico hasta la visita en consultas externas fue de 5,7 días y el tiempo medio desde el diagnóstico hasta el inicio del tratamiento de 45 días.Conclusiones: Durante este año de pandemia de COVID-19 hemos podido asegurar la asistencia y tratamiento de las mujeres con cáncer de mama con adecuados intervalos entre el diagnóstico y el tratamiento. A este proceso ha contribuido la implementación previa de la cirugía mayor ambulatoria en el cáncer de mama. (AU)

Introduction: The COVID-19 pandemic has had an important impact in all areas; health service has been one of the most affected. The pandemic has led to a reorganization of human and material resources and has caused a saturation of the health service. As specialists in breast cancer, we have adapted to this situation by reorganizing and adapting care to the professional environments and infrastructures that were available when necessary. The incidence has varied during 2020 and it has made possible to normalize the work on some occasions. We would like to describe our experience in breast cancer surgery during this COVID-19 pandemic year.Material and methods: Retrospective observational study of patients operated on breast cancer from 14th March 2020 to 14th March 2021.Result: A number of 138 breast cancer have been operated on 136 women. The average age is 62 years (36-8); there were 86 patients operated on major ambulatory surgery regimen (63.2%) and 50 patients (36.8%) were hospitalized. The average time from diagnosis to outpatient visit was 5.7 days and the average time from diagnosis to the beginning of the treatment of 45 days.Conclusions: During this COVID-19 pandemic year, we have been able to ensure the care and treatment of women with breast cancer with adequate time intervals between diagnosis and treatment. This process has also been favored by the prior establishment of major ambulatory surgery in our medical center.

Optimization of a technology-supported physical activity promotion intervention for breast cancer survivors: Results from Fit2Thrive.

BACKGROUND: The benefits of moderate to vigorous physical activity (MVPA) for breast cancer survivors are well established. However, most are insufficiently active. Fit2Thrive used the Multiphase Optimization Strategy methodology to determine the effect of 5 intervention components on MVPA in this population. METHODS: Two hundred sixty-nine participants (mean age, 52.5 years; SD, 9.9 years) received a core intervention (the Fit2Thrive self-monitoring app and Fitbit) and were randomly assigned to 5 intervention components set to on/off in a full factorial experiment: support calls, deluxe app, buddy, online gym, and text messages. The intervention was delivered over 12 weeks with a 12-week follow-up. MVPA was measured via accelerometry at the baseline (T1), at 12 weeks (T2), and at 24 weeks (T3). The main effects and interaction effects at each time point were examined for all components. RESULTS: Trial retention was high: 91.8% had valid accelerometer data at T2 or T3. Across all conditions, there were significant increases in MVPA (+53.6 min/wk; P < .001) and in the proportion of survivors meeting MVPA guidelines (+22.3%; P < .001) at T2 that were maintained but attenuated at T3 (MVPA, +24.6 min/wk; P < .001; meeting guidelines, +12.6%; P < .001). No individual components significantly improved MVPA, although increases were greater for the on level versus the off level for support calls, buddy, and text messages at T2 and T3. CONCLUSIONS: The Fit2Thrive core intervention (the self-monitoring app and Fitbit) is promising for increasing MVPA in breast cancer survivors, but the components provided no additional increases in MVPA. Future research should evaluate the core intervention in a randomized trial and determine what components optimize MVPA behaviors in breast cancer survivors.

Upper limb rehabilitation system based on virtual reality for breast cancer patients: Development and usability study.

BACKGROUND: Functional exercise is crucial for breast cancer patients after surgery, and the use of virtual reality technology to assist patients with postoperative upper limb functional rehabilitation has gradually attracted the attention of researchers. However, the usability of the developed rehabilitation system is still unknown to a large extent. The purpose of this study was to develop a virtual reality upper limb rehabilitation system for patients after breast cancer surgery and to explore its usability. METHODS: We built a multidisciplinary team based on virtual reality and human-computer interaction technology and designed and developed an upper limb function rehabilitation system for breast cancer patients after surgery. Breast cancer patients were recruited from a grade III-a general hospital in Changchun city for the experiment. We used the System Usability Scale to evaluate the system availability, the Presence Questionnaire scale to measure the immersive virtual reality scene, and the Simulator Sickness Questionnaire subjective measurement scale for simulator sickness symptoms. RESULTS: This upper limb rehabilitation system hardware consisted of Head-mounted Display, a control handle and notebook computers. The software consisted of rehabilitation exercises and game modules. A total of 15 patients were tested on this system, all of whom were female. The mean age was 54.73±7.78 years, and no patients were excluded from the experiment because of adverse reactions such as dizziness and vomiting. The System Usability Scale score was 90.50±5.69, the Presence Questionnaire score was 113.40±9.58, the Simulator Sickness Questionnaire-nausea score was 0.93±1.16, the Simulator Sickness Questionnaire-oculomotor score was 0.80±1.27, the Simulator Sickness Questionnaire-disorientation score was 0.80±1.27, and the Simulator Sickness Questionnaire total score was 2.53±3.40. CONCLUSIONS: This study fills in the blanks regarding the upper limb rehabilitation of breast cancer patients based on virtual reality technology system usability research. As the starting point of research in the future, we will improve the system's function and design strictly randomized controlled trials, using larger samples in the promotion, to evaluate its application in breast cancer patients with upper limbs and other physiological functions and the feasibility and effects of rehabilitation.

Cuidados de salud en pacientes mastectomizadas: Revisión bibliográfica / Health care in mastectomized patients: Literature review

Introducción: El cáncer de mama es la neoplasia más frecuente en la mujer tanto en España como a nivel mundial, considerándose un gran problema para la salud pública. El cribado se realiza mediante la mamografía. Actualmente el enfoque terapéutico incluye tratamiento quirúrgico, existiendo la posibilidad de cirugía conservadora o no conservadora o mastectomía. Esta segunda opción fue introducida por Halsted y Meyer como intervención pautada, con bases científicas, en el año 1890. Hoy día sigue realizándose, desencadenando un gran impacto en todos los ámbitos de la vida de la mujer. Objetivo: Establecer los cuidados de salud apropiados para mujeres con cáncer de mama sometidas o en previsión de ser sometidas a una mastectomía, por parte de los profesionales de enfermería. Metodología: Esta revisión bibliográfica siguió el protocolo PRISMA. Los artículos seleccionados fueron únicamente ensayos clínicos aleatorizados (ECA). La búsqueda bibliográfica se realizó en las bases de datos Medline, Cinahl y Scopus mediante los términos MeSH “mastectomíy” , “nursing care” y “clincal trial” y el operador boleano “AND”. Se encontraron 20 artículos que cumplían los criterios de inclusión, y fueron transferidos al software Mendeley Desktop. Resultados: Tras una serie de cribados, fueron 9 los artículos incluidos en la revisión bibliográfica. Se midió su calidad metodológica mediante la escala PEDro. Conclusiones: A pesar de la gran incidencia del cáncer de mama, así como de la mastectomía, existen pocos ensayos clínicos aleatorizados publicados. Por tanto, sería interesante profundizar más respecto a este tema en futuras líneas de investigación.(AU)

Introduction: Breast cancer is the most frequent neoplasm in women both in Spain and worldwide, being considered a big problem for public health. Screening is done by a mammogram. Currently, therapy includes surgical treatment which could be breast-conserving surgery or mastectomy. The second option was introduced like a formal procedure by Hasteld and Meyer in 1890. It is still done nowadays, meaning a great impact for women in all fields of their lives. Purpose: Establish the appropriate health care for women with breast cancer who have been undergoing or will be undergoing a mastectomy, by nurses. Material and methods: This systematic review followed the protocol PRISMA. The selected articles were just randomized clinical trials (RCTs). The searching was made in Medline, Cinahl and Scopus databases by the Mesh terms “mastectomy”, “nursing care” and “clinical trial” and the boolean operator “AND”. Twenty articles that included inclusion criteria were found and transferred to Mendeley Desktop software. Outcomes: After articles were narrowed down, nine of them were included in the systematic review. Their methodological quality was measured by the PEDro scale. Conclusion: Despite the high incidence of breast cancer and mastectomy, there are a few published RCTs about that. Therefore, it would be interesting to go deeper into this topic in future lines of research.(AU)

Low-frequency exercise training improves cardiovascular fitness and strength during treatment for breast cancer: a single-arm intervention study.

Aerobic and resistance exercise during and after cancer treatment are important for health-related outcomes, however treatment-specific barriers may inhibit adherence. We explored the effect of lower-frequency exercise training on fitness, body composition, and metabolic markers (i.e. glucose and lipids) in a group of recently diagnosed breast cancer patients. Fifty-two females ≥ 18 years with stage I-IIIB breast cancer were instructed to attend 2 cardiovascular and strength training sessions/week over 12 weeks, but program length was expanded as needed to accommodate missed sessions. Pre- and post-intervention, we measured: (1) cardiovascular fitness, (2) isometric strength, (3) body composition (dual-energy X-ray absorptiometry), and (4) fasting glucose, insulin, c-peptide, and lipids. Pre-intervention, participants were 53 ± 10 years old (mean ± SD) and overweight (BMI: 27.5 ± 5.4 kg m-2, 40.1 ± 6.5% body fat). Forty participants completed the program over a median 20 weeks (range: 13-32 weeks, median frequency: 1.2 sessions/week), over which predicted VO2peak improved by 7% (2.2[0.1-4.4] mL/kg/min) (delta[95% CI]), and strength increased by 7-9% (right arm: 2.3[0.1-4.5] N m; right leg: 7.9[2.1-13.7] N m; left leg: 7.8[1.9-13.7] N m). Body composition and metabolic markers were unchanged. An exercise frequency of 1.2 sessions/week stimulated significant improvements in fitness, and may represent a practical target for patients during active treatment.

Exercise versus usual care after non-reconstructive breast cancer surgery (UK PROSPER): multicentre randomised controlled trial and economic evaluation.

OBJECTIVE: To evaluate whether a structured exercise programme improved functional and health related quality of life outcomes compared with usual care for women at high risk of upper limb disability after breast cancer surgery. DESIGN: Multicentre, pragmatic, superiority, randomised controlled trial with economic evaluation. SETTING: 17 UK National Health Service cancer centres. PARTICIPANTS: 392 women undergoing breast cancer surgery, at risk of postoperative upper limb morbidity, randomised (1:1) to usual care with structured exercise (n=196) or usual care alone (n=196). INTERVENTIONS: Usual care (information leaflets) only or usual care plus a physiotherapy led exercise programme, incorporating stretching, strengthening, physical activity, and behavioural change techniques to support adherence to exercise, introduced at 7-10 days postoperatively, with two further appointments at one and three months. MAIN OUTCOME MEASURES: Disability of Arm, Hand and Shoulder (DASH) questionnaire at 12 months, analysed by intention to treat. Secondary outcomes included DASH subscales, pain, complications, health related quality of life, and resource use, from a health and personal social services perspective. RESULTS: Between 26 January 2016 and 31 July 2017, 951 patients were screened and 392 (mean age 58.1 years) were randomly allocated, with 382 (97%) eligible for intention to treat analysis. 181 (95%) of 191 participants allocated to exercise attended at least one appointment. Upper limb function improved after exercise compared with usual care (mean DASH 16.3 (SD 17.6) for exercise (n=132); 23.7 (22.9) usual care (n=138); adjusted mean difference 7.81, 95% confidence interval 3.17 to 12.44; P=0.001). Secondary outcomes favoured exercise over usual care, with lower pain intensity at 12 months (adjusted mean difference on numerical rating scale -0.68, -1.23 to -0.12; P=0.02) and fewer arm disability symptoms at 12 months (adjusted mean difference on Functional Assessment of Cancer Therapy-Breast+4 (FACT-B+4) -2.02, -3.11 to -0.93; P=0.001). No increase in complications, lymphoedema, or adverse events was noted in participants allocated to exercise. Exercise accrued lower costs per patient (on average -£387 (€457; $533) (95% confidence interval -£2491 to £1718; 2015 pricing) and was cost effective compared with usual care. CONCLUSIONS: The PROSPER exercise programme was clinically effective and cost effective and reduced upper limb disability one year after breast cancer treatment in patients at risk of treatment related postoperative complications.

Motivational strategies to improve adherence to physical activity in breast cancer survivors: A systematic review and meta-analysis.

Two behavioral change-based strategies for promoting adherence to physical activity (PA) suggested to have the greatest potential are the pedometer and Motivational Interviewing (MI). However, there are no comparisons between these two strategies identifying which one is more effective for improving PA adherence. This systematic review and meta-analysis aimed to determine which PA motivation strategy is more effective for promoting adherence to self-directed PA in female breast cancer survivors. Studies implementing self-directed PA which used a step tracker and/or MI for motivation in female breast cancer survivors were identified from the following databases at two timepoints, September 2019 and June 2020: CENTRAL, PubMed, CINAHL, PsycINFO, and Sportdiscuss. Sixteen randomized controlled trials (RCTs) were selected for data extraction, whereas ten RCTs were included in meta-analysis. Meta-analysis was performed on pooled data to estimate the standardized mean differences in PA duration and step count, and 95% confidence intervals. The number of participants meeting PA recommendations was also analyzed. Subgroup analysis was performed for three motivational strategies (pedometer combined with counselling, with print material or with motivational interviewing). Meta-analysis showed that pedometer combined with another intervention has a small effect on step count (p = 0.03) and a moderate effect on duration of moderate-vigorous physical activity (MVPA) (p = <0.0001) compared to controls. Additionally, motivational strategies increase the number of participants who meet a PA goal (p = 0.005). The findings of this review endorse the use of a step tracker combined with counselling, print material or MI based on behavioral change theory. This approach provided the most consistent positive effect on adherence to self-directed PA among breast cancer survivors. Future studies should evaluate differences between measures of adherence to self-directed PA, to identify the best motivation strategy for improving patient adherence and health outcomes. Systematic review registration: PROSPERO Registration number CRD42020148542.

Prevalence and associations of axillary web syndrome in Asian women after breast cancer surgery undergoing a community-based cancer rehabilitation program.

BACKGROUND: Patients who have breast cancer surgery are at risk of axillary web syndrome (AWS), an under-recognized postsurgical complication which can result in shoulder morbidity and functional impairment. Emerging studies have indicated that AWS may persist beyond the first few months after surgery, although few studies have assessed the prevalence and association of AWS beyond a year after diagnosis. Therefore, the aim of this study was to investigate the prevalence and associations for AWS in post-operative breast cancer patients up to 3 years after surgery. METHODS: This cross sectional observational study was conducted at a community-based cancer rehabilitation center. Patients were evaluated for the presence of AWS via physical examination. Disease-related data was obtained from clinical review and medical records. Descriptive statistics were utilized to illustrate patient demographics and clinical characteristics. Logistic regression analyses were used to determine associations of AWS. RESULTS: There were 111 Asian women who were recruited, who had undergone breast surgery and were referred to a national outpatient rehabilitation center. The prevalence of AWS in this population was 28.9%. In the multivariate regression model, significant factors were age < 50 years (OR = 3.51; 95% CI = 1.12-11.0; p = 0.031) and ALND (OR = 6.54; 95% CI = 1.36-31.3; p = 0.019). There was reduced shoulder flexion ROM (p < 0.001) in patients with AWS compared to patients without AWS. CONCLUSIONS: A high prevalence of AWS was reported in breast cancer survivors even at 3 years after breast surgery. Our findings highlight the need to identify breast cancer survivors with AWS even in the survivorship phase, and develop strategies to raise awareness and minimize functional impairment in these patients.

Different endurance exercises modulate NK cell cytotoxic and inhibiting receptors.

PURPOSE: Induction of IDO depends on the activation of AhR forming the AhR/IDO axis. Activated AhR can transcribe various target genes including cytotoxic and inhibiting receptors of NK cells. We investigated whether AhR and IDO levels as well as activating (NKG2D) and inhibiting (KIR2DL1) NK cell receptors are influenced by acute exercise and different chronic endurance exercise programs. METHODS: 21 adult breast and prostate cancer patients of the TOP study (NCT02883699) were randomized to intervention programs of 12 weeks of (1) endurance standard training or (2) endurance polarized training after a cardiopulmonary exercise test (CPET). Serum was collected pre-CPET, immediately post-CPET, 1 h post-CPET and after 12 weeks post-intervention. Flow cytometry analysis was performed on autologous serum incubated NK-92 cells for: AhR, IDO, KIR2DL1 and NKG2D. Differences were investigated using analysis-of-variance for acute and analysis-of-covariance for chronic effects. RESULTS: Acute exercise: IDO levels changed over time with a significant increase from post-CPET to 1 h post-CPET (p = 0.03). KIR2DL1 levels significantly decreased over time (p < 0.01). NKG2D levels remained constant (p = 0.31). Chronic exercise: for both IDO and NKG2D a significant group × time interaction, a significant time effect and a significant difference after 12 weeks of intervention were observed (IDO: all p < 0.01, NKG2D: all p > 0.05). CONCLUSION: Both acute and chronic endurance training may regulate NK cell function via the AhR/IDO axis. This is clinically relevant, as exercise emerges to be a key player in immune regulation.

Objetivo: evaluar la asociación entre la fuerza de prensión manual (FPM) y diversos parámetros de condición física y composición corporal en mujeres supervivientes de cáncer de mama.Método: se realizó un estudio transversal con los datos basales del ensayo clínico EFICAN (Ejercicio FÍsico para supervivientes de CÁNcer de mama). Participaron 60 mujeres supervivientes de cáncer de mama que habían terminado los tratamientos centrales de la enfermedad en los 10 años previos al comienzo del estudio, que no presentaban enfermedad pulmonar o cardiovascular, cáncer de mama metastásico, ni tenían prevista una intervención para reconstrucción mamaria en un plazo de 3 meses desde el comienzo del estudio. Se evaluó la fuerza de prensión manual mediante dinamometría manual, la fuerza muscular isométrica pico mediante dinamometría electromecánica funcional, el fitness cardiorrespiratorio (VO2máx) se estimó a través del Siconolfi step test, la amplitud de movimiento (ADM) en flexión de hombro mediante goniometría digital, y la composición corporal mediante bioimpedancia.Resultados: se observó una asociación positiva de la FPM con la masa muscular (r=0.423), y con la fuerza isométrica de miembro superior (r=0.523) e inferior (r=0.335), y una asociación negativa de la FPM con el porcentaje de grasa corporal (r=-0.405). Sin embargo, no se encontró asociación entre FPM y VO2máx ni ADM del hombro (P>0.05).Conclusiones: estos resultados sugieren que la FPM puede ser un buen indicador de fuerza muscular, así como de composición corporal en mujeres supervivientes de cáncer de mama. Futuros estudios prospectivos deberán evaluar el valor predictivo de la FPM en esta población. (AU)

Objectives: this study evaluated the association between handgrip strength (HGS) and various parameters of physical fitness and body composition in female breast cancer survivors.Methods: a cross-sectional study was conducted with the baseline data from the EFICAN (Ejercicio FÍsico para supervivientes de CÁNcer de mama) clinical trial. 60 female breast cancer survivors who had completed the core treatments of the disease in the 10 years prior to the study beginning, who didn’t have any cardiovascular or pulmonary disease, metastatic breast cancer or awaited breast cancer reconstruction in the following 3 months, participated. Handgrip strength was assessed using a digital dynamometer, peak isometric strength was determined using an electromechanical dynamometer, cardiorespiratory fitness (VO2máx) was estimated through the Siconolfi step test, shoulder flexion mobility was assessed through digital goniometry and body composition was determined using a bioelectrical impedance device.Results: positive associations between HGS and muscle mass (r=0.423), isometric upper-limb (r=0.523) and lower-limb (r=0.335) strength were found, and a negative association between HGS and fat mass percentage (r=-0.405) was also found. However, no associations between HGS and VO2máx or shoulder flexion mobility were found (P>0.05).Conclusions: these results suggest that HGS may be a good indicator of muscular strength and body composition in female breast cancer survivors. Future prospective studies are needed to assess the predictive value of HGS in this population. (AU)

Objetivo: avaliar a associação entre a força de preensão manual (FPM) e vários parâmetros de condição física e composição corporal em mulheres sobreviventes de cancro da mama.Método: foi realizado um estudo transversal utilizando dados de base do ensaio clínico EFICAN (Physical Exercise for Breast Cancer Survivors). Participaram sessenta mulheres sobreviventes de cancro da mama que tinham concluído os tratamentos centrais da doença nos 10 anos anteriores ao início do estudo, que não tinham doenças pulmonares ou cardiovasculares, cancro da mama metastásico, ou que não estavam programadas para se submeterem à reconstrução da mama nos 3 meses seguintes ao início do estudo. A força de preensão manual foi avaliada por dinamometria manual, o pico de força muscular isométrica por meio de dinamometria electromecânica funcional, a capacidade cardiorrespiratória (VO2máx) foi estimada pelo Siconolfi step test, a amplitude de movimento (ADM) em flexão do ombro por meio de goniometria digital, e a composição corporal por bioimpedância.Resultados: observámos uma associação positiva de FPM com massa muscular (r=0,423), e com força isométrica de membro superior (r=0,523) e membro inferior (r=0,335), e uma associação negativa de FPM com percentagem de gordura corporal (r=-0,405). Contudo, não foi encontrada qualquer associação entre FPM e VO2max ou ADM de ombro (P>0.05).Conclusões: estes resultados sugerem que a FPM pode ser um bom indicador da força muscular, bem como da composição corporal das mulheres sobreviventes de cancro da mama. Os futuros estudos prospectivos devem avaliar o valor preditivo do FPM nesta população. (AU)

Rehabilitation interventions to support return to work for women with breast cancer: a systematic review and meta-analysis.

BACKGROUND: Research recommends the development and evaluation of interventions to support women with breast cancer in returning to, or managing, work. Despite this, there has historically been a paucity of rehabilitation interventions to support women with breast cancer to maintain or return to their work role. The aim of this systematic review was to examine key characteristics of rehabilitation interventions, and their effectiveness on work outcomes for women with breast cancer, compared to usual care. METHODS: A systematic review was conducted of controlled studies of rehabilitation interventions with work outcomes for women with breast cancer. Six databases were systematically searched: EMBASE, Web of Science, MEDLINE (OVID), CINAHL, PsycINFO, and the Cochrane Central Register of Controlled Trials (CENTRAL). Results are presented either as pooled odds ratio (OR) or pooled effect size (hedges g) between groups, with 95% confidence intervals (CI). Narrative synthesis was conducted on intervention outcomes not suitable for meta-analysis. RESULTS: Five thousand, five hundred and thirty-five studies were identified. Nine out of 28 abstracts met inclusion criteria. Heterogeneity of interventions and outcomes precluded meta-analysis for most outcomes. Of the interventions included in meta-analysis, no significant differences compared to usual care were found for sick leave (2 studies (12 months); OR 1.11 (95% CI: 0.66 to 1.87), number of sick days taken (2 studies (six months); difference in effect: - 0.08, (95% CI: - 0.48 to 0.38) or working hours (2 studies (12 months); 0.19, (95% CI: - 0.20 to 0.64). Only one study, with a multidisciplinary intervention, showed a significant difference for work outcomes when compared to usual care. Work-specific content featured in three interventions only, none of which provided conclusive evidence for improvement in work outcomes. Enhanced physical and psychological sequalae, and quality of life was observed in some studies. CONCLUSION: There remains a lack of effective and methodologically rigorous rehabilitation intervention studies for breast cancer survivors. The development and evaluation of effective rehabilitation interventions to support return to work is warranted.
