The Case for Prehabilitation Prior to Breast Cancer Treatment

Evaluation of the clinical effect of a multimodal pre-rehabilitation program guided by the behaviour change wheel in elderly women with breast cancer

BACKGROUND

This study aims to explore the nursing effect of a multimodal pre-rehabilitation programme guided by BCW theory on elderly women patients with breast cancer.

METHODS

The participants were divided into two groups. The study group was administered with the pre-rehabilitation model guided by BCW theory; the control group was administered with conventional methods. The rehabilitation effects of the two groups were compared..

RESULTS

The scores of RISC, PTGI and FACT-B were higher in the study group(P < 0.05). The SUPPH score and ROM compliance rate were higher in the study group (P < 0.05) (96% vs 72%). The avoidance score and yield score were lower in the study group(P < 0.05).

CONCLUSION

A multimodal pre-rehabilitation program guided by BCW theory can significantly improve the quality of life and functional status of elderly women patients with breast cancer, and its popularisation and application are recommended.

Prehabilitation for Patients with Cancer Undergoing Radiation Therapy: a Scoping Review

AIMS

Prehabilitation is a process of identifying and assessing factors that could compromise the physical and psychological health of patients undergoing cancer treatment and implementing an intervention to combat such concerns. The use of prehabilitation in cancer surgery has yielded positive outcomes in rectal, lung and abdominal cancers. Prehabilitation strategies have potential to improve the management of patients receiving radiation therapy or chemoradiation. The aim of the present study was to map the evidence of the assessment and evaluation of prehabilitation for radiation therapy patients.

MATERIALS AND METHODS

A database search using EMBASE and PubMed was conducted. The PRISMA guidelines were adhered to. Keywords included prehabilitation, radiation therapy/radiotherapy, chemoradiotherapy/chemoradiation, intervention and exercise. Types of prehabilitation strategy, their purposes and impact, according to cancer site, were analysed.

RESULTS

Prehabilitation is most commonly evaluated in head and neck cancer, whereby unimodal, physical interventions manage dysphagia. Prehabilitation for lung cancer demonstrated its ability to widen treatment options for patients. Physical prehabilitation is administered to combat adverse effects of neoadjuvant chemoradiation therapy in patients with rectal cancer.

CONCLUSION

Prehabilitation is adaptive and tailored to specific patient and site needs; thus it is applied across a wide range of cancer sites. More interventions by which radiation therapy is the definitive treatment modality and larger sample sizes within these studies are warranted to increase prehabilitation utilisation for patients undergoing radiation therapy.

Feasibility study of a multimodal prehabilitation programme in women receiving neoadjuvant therapy for breast cancer in a major cancer hospital: a protocol

INTRODUCTION

Neoadjuvant therapy has become a standard treatment for patients with stage II/III HER2 positive and triple negative breast cancer, and in well-selected patients with locally advanced and borderline resectable high risk, luminal B breast cancer. Side effects of neoadjuvant therapy, such as fatigue, cardiotoxicity, neurotoxicity, anxiety, insomnia, vasomotor symptoms, gastrointestinal disturbance as well as a raft of immune-related adverse events, may impact treatment tolerance, long-term outcomes, and quality of life. Providing early supportive care prior to surgery (typically termed 'prehabilitation') may mitigate these side effects and improve quality of life.During our codesign of the intervention, consumers and healthcare professionals expressed desire for a programme that 'packaged' care, was easy to access, and was embedded in their care pathway. We hypothesise that a multimodal supportive care programme including exercise and complementary therapies, underpinned by behavioural change theory will improve self-efficacy, quality of life, readiness for surgery and any additional treatment for women with breast cancer. We seek to explore cardiometabolic, residual cancer burden and surgical outcomes, along with chemotherapy completion (relative dose intensity). This article describes the protocol for a feasibility study of a multimodal prehabilitation programme.

METHODS AND ANALYSIS

This is a prospective, mixed-method, feasibility study of a multi-modal programme in a hospital setting for 20-30 women with breast cancer receiving neoadjuvant therapy. Primary outcomes are recruitment rate, retention rate, adherence and acceptability. Secondary outcomes include patient reported outcome measures (PROMs), surgical outcomes, length of stay, satisfaction with surgery, chemotherapy completion rates, changes in metabolic markers and adverse events. Interviews and focus groups to understand the experience with prehabilitation and different factors that may affect feasibility of the intervention . The output of this study will be a codesigned, evidence-informed intervention assessed for feasibility and acceptability by women with breast cancer and the healthcare professionals that care for them.

ETHICS AND DISSEMINATION

The study received ethics approval from the St Vincents Hospital HREC (HREC/2021/ETH12198). Trial results will be communicated to participants, healthcare professionals, and the public via publication and conferences.

Prehabilitation in radiation therapy: a scoping review

PURPOSE/OBJECTIVES

Radiation therapy (RT) is a central component of cancer treatment with survival and long-term quality-of-life benefits across a spectrum of oncologic diagnoses. However, RT has been associated with varying levels of fatigue, pain, weight loss, and changes in mental health both during and post-treatment. Prehabilitation aims to optimize health prior to anti-neoplastic therapy in order to reduce side effects, increase adherence to treatment, expedite post-treatment recovery, and improve long-term outcomes. Though prehabilitation has been studied in those undergoing cancer-related surgery, literature on prehabilitation in individuals undergoing RT has not been comprehensively explored. Thus, this scoping review aims to summarize the existing literature focused on prehabilitation interventions for patients receiving RT.

MATERIALS/METHODS

The PRISMA-ScR checklist for conducting scoping reviews was adopted to identify and evaluate studies investigating the efficacy of prehabilitation before and during RT for cancer over the past 21 years (10/2002-10/2022). A search of prehabilitation and RT was performed to identify studies investigating prehabilitation interventions in adult cancer patients undergoing RT.

RESULTS

A total of 30 articles met inclusion criteria, yielding 3657 total participants. Eighteen (60%) studies were randomized controlled trials (RCTs) with sample sizes ranging from 21 to 221. The most commonly studied populations were patients with head and neck cancer, followed by rectal, breast, and lung cancer. A majority (80%) of studies evaluated one prehabilitation intervention (i.e., unimodal). Targeted physical exercises were the most common intervention, followed by general physical exercises and technology/apps. Adherence/feasibility was the most common primary outcome, representing 30% of studies. All studies reported data on sex, and 5 (17%) reported data on race and/or ethnicity.

CONCLUSIONS

Prehabilitation interventions have been successfully implemented in patients with cancer undergoing surgical treatment. Based on limited current literature, prehabilitation appears to have a promising effect in reducing morbidity in adult cancer patients requiring RT. Though our review identified many RCTs, they were frequently small sample trials with primary outcomes focused on feasibility, rather than functional status or quality of life. Thus, there is a need for adequately powered, randomized controlled intervention trials to investigate the efficacy of prehabilitation and maximize the treatment outcomes for patients undergoing RT.

Prehabilitation in Patients With Breast Cancer Receiving Neoadjuvant Therapy to Minimize Musculoskeletal Postoperative Complications and Enhance Recovery (PREOPtimize): A Protocol for a Randomized Controlled Trial

OBJECTIVE

The aim of this study is to assess the effects of a prehabilitation program (PREOPtimize), consisting of Nordic Walking and resistance training exercises plus health education among patients with breast cancer, who are receiving neoadjuvant therapy to enhance postoperative functionality of the affected arm. A secondary aim will be to compare the short-term effects of the intervention on other patient-reported outcome measures.

METHODS

This will be an assessor-blind, randomized controlled trial with a parallel group design conducted at a tertiary hospital. A sample of 64 patients with breast cancer scheduled for surgery and undergoing neoadjuvant chemotherapy will be recruited for the trial and randomly allocated to either (1) a prehabilitation program consisting of 2 weekly sessions of 75 minutes of Nordic Walking, muscle strengthening exercises, and health education sessions conducted between the fourth month of treatment and surgery or (2) usual care. Patients in both groups will be assessed at baseline, before surgery, and at 1 and 3 months after surgery. Assessed outcomes include functionality of the affected arm (QuickDash), arm volume, range of motion, handgrip strength, pain, fatigue, functional capacity, physical activity levels, and health-related quality of life. Adherence to the intervention in the prehabilitation group and adverse events will also be recorded.

IMPACT

Prehabilitation for patients affected by breast cancer is rarely implemented in clinical practice. The results obtained with the PREOPtimize trial could show that prehabilitation is a feasible intervention for patients with breast cancer receiving neoadjuvant therapy that might enhance postoperative recovery of upper arm function as well as improve overall physical performance and health-related quality of life.

Social-cognitive, demographic, clinical, and health-related correlates of physical activity and sedentary behaviour in newly diagnosed women with breast cancer

PURPOSE

Identifying correlates of physical activity and sedentary behaviour allows for the identification of factors that may be targeted in future behaviour change interventions. This study sought to determine the social-cognitive, demographic, clinical, and health-related correlates of physical activity and sedentary behaviour in individuals recently diagnosed with breast cancer.

METHODS

Data were collected from 1381 participants within 90 days of diagnosis in the Alberta Moving Beyond Breast Cancer (AMBER) Cohort Study. Physical activity and sedentary behaviour were measured with ActiGraph GT3X+® and activPALTM devices, respectively, for seven consecutive days. Correlates were collected via a self-reported questionnaire, medical record extraction, or measured by staff.

RESULTS

Multivariable models were fitted for sedentary behaviour, light physical activity, and moderate-to-vigorous physical activity. Greater sedentary behaviour was associated with higher body fat percentage (BF%) (ß=0.044; p<0.001) and being single (ß=0.542; p<0.002). Lower light physical activity was associated with higher BF% (ß=-0.044; p<0.001), higher body mass index (ß=-0.039; p<0.001), greater disease barrier influence (ß=-0.006; p<0.001), a HER2-positive diagnosis (ß=-0.278; p=0.001), and being single (ß=-0.385; p= 0.001). Lower moderate-to-vigorous physical activity was associated with higher BF% (ß =-0.011; p=0.001), greater disease barrier influence (ß=-0.002; p<0.001), and being of Asian (ß=-0.189; p=0.002) or Indian/South American (ß=-0.189; p=0.002) descent. Greater moderate-to-vigorous physical activity was associated with having greater intentions (ß=0.049; p=0.033) and planning (ß=0.026; p=0.015) towards physical activity.

CONCLUSION

Tailoring interventions to increase physical activity for individuals recently diagnosed with breast cancer may improve long-term outcomes across the breast cancer continuum.

A narrative review of heart failure with preserved ejection fraction in breast cancer survivors

Advances in breast cancer (BC) treatment have contributed to improved survival, but BC survivors experience significant short-term and long-term cardiovascular mortality and morbidity, including an elevated risk of heart failure with preserved ejection fraction (HFpEF). Most research has focused on HF with reduced ejection fraction (HFrEF) after BC; however, recent studies suggest HFpEF is the more prevalent subtype after BC and is associated with substantial health burden. The increased HFpEF risk observed in BC survivors may be explained by treatment-related toxicity and by shared risk factors that heighten risk for both BC and HFpEF. Beyond risk factors with physiological impacts that drive HFpEF risk, such as hypertension and obesity, social determinants of health (SDOH) likely contribute to HFpEF risk after BC, impacting diagnosis, management and prognosis.Increasing clinical awareness of HFpEF after BC and screening for cardiovascular (CV) risk factors, in particular hypertension, may be beneficial in this high-risk population. When BC survivors develop HFpEF, treatment focuses on initiating guideline-directed medical therapy and addressing underlying comorbidities with pharmacotherapy or behavioural intervention. HFpEF in BC survivors is understudied. Future directions should focus on improving HFpEF prevention and treatment by building a deeper understanding of HFpEF aetiology and elucidating contributing risk factors and their pathogenesis in HFpEF in BC survivors, in particular the association with different BC treatment modalities, including radiation therapy, chemotherapy, biological therapy and endocrine therapy, for example, aromatase inhibitors. In addition, characterising how SDOH intersect with these therapies is of paramount importance to develop future prevention and management strategies.

Evaluating the effect of upper-body morbidity on quality of life following primary breast cancer treatment: a systematic review and meta-analysis

PURPOSE

Improvements in breast cancer management continue to increase survival and life expectancy after treatment. Yet the adverse effects of treatment may persist long term, threatening physical, psychological, and social wellbeing, leading to impaired quality of life (QOL). Upper-body morbidity (UBM) such as pain, lymphoedema, restricted shoulder range of motion (ROM), and impaired function are widely reported after breast cancer treatment, but evidence demonstrating its impact on QOL is inconsistent. Therefore, the aim of the study was to conduct a systematic review and meta-analysis evaluating the effect of UBM on QOL following primary breast cancer treatment.

METHODS

The study was prospectively registered on PROSPERO (CRD42020203445). CINAHL, Embase, Emcare, PsycInfo, PubMed/Medline, and SPORTDiscus databases were searched for studies reporting QOL in individuals with and without UBM following primary breast cancer treatment. Primary analysis determined the standardised mean difference (SMD) in physical, psychological, and social wellbeing scores between UBM + /UBM - groups. Secondary analyses identified differences in QOL scores between groups, according to questionnaire.

RESULTS

Fifty-eight studies were included, with 39 conducive to meta-analysis. Types of UBM included pain, lymphoedema, restricted shoulder ROM, impaired upper-body function, and upper-body symptoms. UBM + groups reported poorer physical (SMD =  - 0.99; 95%CI =  - 1.26, - 0.71; p < 0.00001), psychological (SMD =  - 0.43; 95%CI =  - 0.60, - 0.27; p < 0.00001), and social wellbeing (SMD =  - 0.62; 95%CI =  - 0.83, - 0.40; p < 0.00001) than UBM - groups. Secondary analyses according to questionnaire showed that UBM + groups rated their QOL poorer or at equal to, UBM - groups across all domains.

CONCLUSIONS

Findings demonstrate the significant, negative impact of UBM on QOL, pervading physical, psychological, and social domains.

IMPLICATIONS FOR CANCER SURVIVORS

Efforts to assess and minimise the multidimensional impact of UBM are warranted to mitigate impaired QOL after breast cancer.

Implementing and sustaining a breast cancer prospective surveillance rehabilitation program: an institutional perspective

BACKGROUND

The prospective surveillance model (PSM) is an evidence-based rehabilitation care delivery model that facilitates functional screening and intervention for individuals undergoing cancer treatment. While PSM is empirically validated and feasible in practice, implementation into cancer care delivery has languished. The purpose of this manuscript is to characterize the barriers and facilitators to implementing PSM in a breast cancer center and to share policy and process outcomes that have sustained the model in practice.

METHODS

The PSM implementation was undertaken as a quality improvement initiative of our cancer center. We retrospectively assessed barriers to implementation and define those according to the Consolidated Framework for Implementation Research (CFIR). Implementation strategies are defined based on the Expert Recommendations for Implementation Change (ERIC) taxonomy. Breast center policy changes and stakeholder-reported process improvement outcomes at the clinic and system level are described.

RESULTS

PSM implementation facilitation was driven primarily by adapting the model to align with the cancer center workflow, engaging interdisciplinary stakeholders as program champions, enhancing knowledge and awareness among cancer care providers, and changing infrastructure to support the model. System and clinic-level policy and process changes included the development of clinical pathways, EHR order sets and automated referrals, new staffing models, and adapted clinical workflows.

CONCLUSION

Our report provides insight on implementing the PSM at a single institution in a cancer care delivery setting. Successful implementation strategies addressed individual, clinic, and system-level barriers and facilitated process and policy changes that have enabled PSM sustainment. Improving integration of rehabilitation services into oncology care has significant implications for survivorship care by enhancing proactive management of functional morbidity.

IMPLICATIONS FOR CANCER SURVIVORS

Improving integration of rehabilitation services into oncology care has significant implications for survivorship care by enhancing proactive management of functional morbidity.

Outcomes of a Multi-Modal Hospital-Associated Home-Based Cancer Prehabilitation Program

OBJECTIVE

To assess the impact of a "one-stop", multi-modal, hospital-associated-home-based prehabilitation model, helmed by a small core team, on newly diagnosed gastrointestinal and urological cancer patients planned for surgery.

METHODS

This is a retrospective study in a tertiary public hospital, involving all newly diagnosed gastrointestinal and urological cancer patients planned for surgery. The primary outcome measure was the 6-minute walk test (6MWT). Other outcomes included physical, psychological and quality-of-life measures, and patient satisfaction surveys, taken at baseline, pre-operatively (post-prehabilitation), and at 3 months post-operatively.

RESULTS

When comparing the baseline to pre-operatively (post-prehabilitation), there was a statistically significant improvement in the 6MWT (21.52 m, p<0.001), 30-Second Sit to Stand test (STS) (1.08 repetitions, p<0.001), Timed Up and Go test (TUG) (0.83 seconds, p=0.014) and Hospital Anxiety and Depression Scale (HADS) (total score 1.77, p<0.001). These were sustained (6MWT: 0.22, p=0.964; STS: 0.08 repetitions, p=0.863; TUG: 0.04 seconds, p=0.939) or further improved (HADS total score 2.06, p=0.003) at 3 months post-operatively. There was also a statistically significant improvement in the EuroQol-5 dimension health score (health-related quality-of-life measure) from baseline to 3 months post-operatively (7.04 points, p=0.001), with more than 90% overall patient satisfaction reported.

CONCLUSION

Prehabilitation applied via our model resulted in significant improvements in functional capacity, psychological and quality-of-life outcomes, sustained at 3 months post-operatively, and is a feasible and effective approach that is well-received by our patients.

Perspectives on the Direction of Cancer Prehabilitation in the Pandemic and Beyond

Growing attention has been placed on cancer prehabilitation in the recent years as the number of publications increase. The real-world application of prehabilitation remains heterogeneous and its implementation has been challenging during the COVID-19 pandemic. However, the pandemic has also provided impetus for change-leveraging technology and digitalization. This paper will discuss the pre-existing models of care, adaptations that had taken place in the pandemic, the model of care in the author's institution, and the future direction of cancer prehabilitation.

Conservative interventions and clinical outcome measures used in the perioperative rehabilitation of breast cancer patients undergoing mastectomy: a scoping review

Background

Mastectomy is the first-line treatment approach for more than 90% of breast cancer patients. The numerous physical impairments associated with this surgical procedure negatively impact the patient’s quality of life. To date, rehabilitation resources available for breast cancer patients undergoing mastectomy within the institutions affiliated to the Centre intégré universitaire de soins de santé et de services sociaux de la Mauricie-et-du-Centre-du-Québec (CIUSSS-MCQ) are lacking and do not always seem to reflect the particularities of breast cancer care pathways. The purpose of this review was to identify and describe the conservative interventions and the clinical outcome measures used in the perioperative physical rehabilitation of women with breast cancer who are awaiting or have undergone mastectomy. We also aimed to report on the barriers and facilitators to study participation and completion.

Methods

MEDLINE, CINAHL, and the Cochrane Library were searched from inception to January 2021, and we updated the search on July 11, 2022. We included peer-reviewed English and French literature with quantitative designs, describing conservative interventions and clinical outcome measures used within rehabilitation programs designed for women who were awaiting or had undergone mastectomy. Paired reviewers independently reviewed all citations and articles using a two-phase screening process and independently extracted the data.

Results

Of the 6080 articles identified, 57 met the inclusion criteria. Most interventions were multimodal, which combined exercise with patient education, manual therapy, and/or lymphatic drainage. The most frequently used objective measures of physical function were shoulder range of motion, muscle strength, and signs of lymphedema. In contrast, the primary patient-reported outcome measures were quality of life, shoulder function, and pain. Undergoing another breast surgery, death, and cancer recurrence were the most reported barriers to study completion.

Conclusion

This scoping review reports on the heterogeneity and wide range of conservative interventions and clinical outcome measures used in the physical rehabilitation of breast cancer patients who had undergone or were scheduled to undergo mastectomy. Tailoring interventions to breast cancer patients’ needs and promoting outpatient rehabilitation interventions appear to be better suited to the particularities of breast cancer care pathways. Further research is needed to better identify barriers and facilitators to study participation and completion.

The Application of Whole-Process Case Management in Patients with Triple-Negative Breast Cancer

Objective

To explore the application of professional whole-process case management during nursing in patients with triple-negative breast cancer.

Methods

This study recruited 60 patients with triple-negative breast cancer who were diagnosed and treated at Department of Breast Surgery in our hospital assessed for eligibility between June 2018 and June 2020, and we assigned them at a ratio of 1 : 1 via the random number table method to receive either general nursing (control group) or professional whole-process case management plus general nursing (observation group). We analyzed and evaluated the hospitalization, the indwelling time of drainage tube, complications, recovery, quality of life, posttraumatic growth, and nursing satisfaction between these two groups at registration, discharge, and the sixth month after surgery, respectively.

Results

Professional whole-process case management achieved a shorter duration of drainage tube placement and hospitalization and a lower incidence of postoperative complications versus general nursing (P < 0.05). Moreover, the observation group had got better recovery (P < 0.05) and a better quality of life at discharge and 6 months after surgery (P < 0.05). Professional whole-process case management obtained higher scores of posttraumatic growth and higher nursing satisfaction versus general nursing (P < 0.05).

Conclusion

Whole-process case management promotes the postoperative recovery of patients with triple-negative breast cancer and shortens the duration of drainage tube indwelling and hospitalization, which lowers the incidence of postoperative complications, improves their quality of life, and enhances nursing satisfaction.

Preoperative Body Image Factors Are Associated with Complications after Breast Reconstruction

BACKGROUND

Psychological factors are broadly understood to contribute to overall health, but their contribution to wound healing is less well defined. Limited data exist on the association of preoperative psychological factors such as body image and postoperative complications. The present study analyzed the association between preoperative body image factors and postoperative complications following breast reconstruction.

METHODS

This was a prospective cohort study of 302 breast cancer patients undergoing breast reconstruction from 2011 to 2015. All patients completed the BREAST-Q; demographics, surgical details, and postoperative complications were recorded. The association of body image factors by means of the BREAST-Q and postoperative complications was analyzed.

RESULTS

On univariate analysis, patients who reported lower preoperative satisfaction with how they appeared in the mirror unclothed, or felt less self-confident or attractive, were significantly more likely to develop an infection postoperatively. Preoperative satisfaction scores were not associated with complications when analyzed in a multivariate fashion. On binomial logistic regression analysis, after controlling for age, body mass index, reconstruction technique, and use of radiotherapy, patients who reported less preoperative satisfaction with how comfortably bras fit or how they appeared in a mirror unclothed were at an increased risk for delayed wound healing.

CONCLUSIONS

Patients with lower preoperative body satisfaction were found to have an increased incidence of infections and delayed wound healing. Although postoperative outcomes are multifactorial, the data suggest that baseline psychological factors such as body image may play a role in postoperative outcomes. Broader use of prehabilitative therapies, targeted at psychosocial factors, may warrant further investigation to optimize postoperative outcomes.

Colorectal cancer pain upon diagnosis and after treatment: a cross-sectional comparison with healthy matched controls

BACKGROUND

The current study sought to explore whether cancer pain (CP) already exists in patients at colorectal cancer (CRC) diagnosis before treatment compared with patients with colorectal cancer (CRC) after treatment and a healthy matched control group. The study also sought to examine whether factors related to physical health status could enhance pain processes.

METHODS

An observational cross-sectional study was conducted following the STROBE checklist. Twenty-nine newly diagnosed and forty post-treatment patients with CRC and 40 healthy age/sex-matched controls were included for comparison. Pain, local muscle function, and body composition outcomes were assessed by a physiotherapist with > 3 years of experience. ANCOVA and Kruskal-Wallis tests were performed, with Bonferroni and Dunn-Bonferroni post hoc analyses and Cohen's d and Hedge's effect size, as appropriate.

RESULTS

The analysis detected lower values of pressure pain threshold (PPT) points, the PPT index, and abdominal strength and higher values of self-reported abdominal pain in newly diagnosed patients, with even more marked results observed in the post-treatment patients, where lower lean mass and skeletal muscle index values were also found than those in the healthy matched controls (p < 0.05). In the post-treatment and healthy matched control groups, positive associations were observed between the PPT lumbar dominant side points and abdominal isometric strength and lean mass, and negative associations were observed between the lumbar dominant side points and body fat (p < 0.05).

CONCLUSION

Upon diagnosis, patients with CRC already show signs of hyperalgesia and central sensitization and deteriorated physical conditions and body composition, and this state could be aggravated by subsequent treatments.

Routine cancer treatments and their impact on physical function, symptoms of cancer-related fatigue, anxiety, and depression

Background and purpose

Breast cancer can be a major challenge for affected women. Knowledge of the physical function, symptoms of cancer-related fatigue, anxiety, and depression based on the cancer treatment may help to guide adequate support.

Methods

For this prospective observational study, we collected data from seventy-nine women with a mean age 54.6 ± 9.5 years prior to the onset of breast cancer treatment (T0) and after (T1/T2). Handgrip strength test (HGS), six-minute walk test (6MWT), the phase angle (PhA), the hospital anxiety and depression scale (HADS), and functional assessment of chronic illness therapy-fatigue (FACIT-F) were used to collect data from four treatment subgroups SC, surgery + chemotherapy; SCR, surgery + chemotherapy + radiation therapy; SR, surgery + radiation therapy; and S, surgery.

Results

A mixed ANOVA revealed a significant interaction between time and group for PhA, F = 8.55, p < 0.01; HGS, F = 3.59, p < 0.01; 6MWT, F = 4.47, p < 0.01; and FACIT-F, F = 2.77, p < 0.05 with most pronounced deterioration seen in group SCR (PhA 4.8°; HGS 27.5 kg, 6MWT 453.4 m, FACIT-F 33.8 points). HADS data displayed moderate anxiety and depression predominantly after treatment.

Conclusion

Our study showed that the extent of change in physical function, symptoms of fatigue, anxiety, and depression depends on the treatment conditions. The potentially higher risk of impaired function due to the prevalence of values below a critical threshold requires early initiated multidisciplinary support.

Prehabilitation, enhanced recovery after surgery, or both? A narrative review

This narrative review presents a biological rationale and evidence to describe how the preoperative condition of the patient contributes to postoperative morbidity. Any preoperative condition that prevents a patient from tolerating the physiological stress of surgery (e.g. poor cardiopulmonary reserve, sarcopaenia), impairs the stress response (e.g. malnutrition, frailty), and/or augments the catabolic response to stress (e.g. insulin resistance) is a risk factor for poor surgical outcomes. Prehabilitation interventions that include exercise, nutrition, and psychosocial components can be applied before surgery to strengthen physiological reserve and enhance functional capacity, which, in turn, supports recovery through attaining surgical resilience. Prehabilitation complements Enhanced Recovery After Surgery (ERAS) care to achieve optimal patient outcomes because recovery is not a passive process and it begins preoperatively.

Lifestyle and Pain following Cancer: State-of-the-Art and Future Directions

This review discusses chronic pain, multiple modifiable lifestyle factors, such as stress, insomnia, diet, obesity, smoking, alcohol consumption and physical activity, and the relationship between these lifestyle factors and pain after cancer. Chronic pain is known to be a common consequence of cancer treatments, which considerably impacts cancer survivors' quality of life when it remains untreated. Improvements in lifestyle behaviour are known to reduce mortality, comorbid conditions (i.e., cardiovascular diseases, other cancer, and recurrence) and cancer-related side-effects (i.e., fatigue and psychological issues). An inadequate stress response plays an important role in dysregulating the body's autonomic, endocrine, and immune responses, creating a problematic back loop with pain. Next, given the high vulnerability of cancer survivors to insomnia, addressing and treating those sleep problems should be another target in pain management due to its capacity to increase hyperalgesia. Furthermore, adherence to a healthy diet holds great anti-inflammatory potential for relieving pain after cancer. Additionally, a healthy diet might go hand in hand with weight reduction in the case of obesity. Consuming alcohol and smoking have an acute analgesic effect in the short-term, with evidence lacking in the long-term. However, this acute effect is outweighed by other harms on cancer survivors' general health. Last, informing patients about the benefits of an active lifestyle and reducing a sedentary lifestyle after cancer treatment must be emphasised when considering the proven benefits of physical activity in this population. A multimodal approach addressing all relevant lifestyle factors together seems appropriate for managing comorbid conditions, side-effects, and chronic pain after cancer. Further research is needed to evaluate whether modifiable lifestyle factors have a beneficial influence on chronic pain among cancer survivors.

Correlation between physical status measures and frailty score in patients undergoing pancreatic resection

BACKGROUND

This study aimed to assess the correlation between validated measures of physical status in a prehabilitation regimen with an established frailty score and analyze changes in these measures after completion of a directed prehabilitation program among patients undergoing elective pancreatic resection.

METHODS

Adult patients undergoing pancreatic resection from 2019-2021 were enrolled in a pilot prehabilitation program. Three validated measures of physical status were used: the 6-minute walk test, grip strength, and chair-stand test. The prehabilitation program comprised 7,500 steps, 30 grip strength exercises, and 100 chair-stand exercises daily. Patients' frailty score was calculated using the Modified Johns Hopkins Frailty score. Changes in physical status measures after prehabilitation and postoperative outcomes were compared.

RESULTS

Thirty-two patients with a median age of 69.0 years (interquartile range = 59.5-76.3 years) were included. Patients' median duration of participation was 21.5 days (interquartile range = 16-29 days). There was a negative correlation between increasing frailty score and baseline the 6-minute walk test (R² = 0.17) and chair-stand test (R² = 0.18). Patients' mean the 6-minute walk test decreased at the end of the prehabilitation program, while grip strength and chair-stand test were unchanged. When stratified by low or intermediate and high frailty scores, the differences in the 6-minute walk test and chair-stand test were unchanged. Hospital duration of stay, complications, and 90-day readmission rates were not different between frailty groups (P > .05).

CONCLUSION

Correlation of physical status measures with frailty score suggests only one of these measures is sufficient to estimate patients' preoperative physical status. A longer, more comprehensive prehabilitation program or an expedited operation are likely the best strategies to improve patient outcomes.

Exploring the impact of exercise and mind-body prehabilitation interventions on physical and psychological outcomes in women undergoing breast cancer surgery

PURPOSE

To compare the impact of exercise and mind-body prehabilitation interventions on changes in quality of life and cancer treatment-related symptoms in women with newly diagnosed breast cancer.

METHODS

The following describes a secondary analysis of a randomized window of opportunity trial (The Pre-Operative Health and Body Study). Forty-nine women were randomized to participate in either an exercise prehabilitation intervention or a mind-body prehabilitation intervention from the time of enrollment to surgery. Participants (N = 47) completed measures of quality of life, anxiety, depression, and stress at the time of enrollment (T1), post-intervention/surgery (T2), and one-month post-surgery (T3). Changes in outcome measures between groups were compared over time using longitudinal models.

RESULTS

Mind-body group participants experienced significant improvements in cognitive functioning in comparison to exercise group participants between T1 and T3 (difference in average change: -9.61, p = 0.04, d = 0.31), otherwise, there were no significant differences between groups. Within group comparisons demonstrated that both groups experienced improvements in anxiety (exercise: average change = -1.18, p = 0.03, d = 0.34; mind-body: average change = -1.69, p = 0.006, d = 0.43) and stress (exercise: average change = -2.33, p = 0.04, d = 0.30; mind-body: average change = -2.59, p = 0.05, d = 0.29), while mind-body group participants experienced improvements in insomnia (average change = -10.03, p = 0.04, d = 0.30) and cognitive functioning (average change = 13.16, p = 0.0003, d = 0.67).

CONCLUSIONS

Both prehabilitation interventions impacted cancer treatment-related symptoms. Further work in larger groups of patients is needed to evaluate the efficacy of prehabilitation interventions on quality of life in women with breast cancer. Pre-operative exercise and mind-body interventions may impact physical and/or psychological effects of cancer diagnosis and treatment in women with breast cancer.

Chemotherapy-induced peripheral neuropathy and rehabilitation: A review

Chemotherapy-induced peripheral neuropathy (CIPN) is a common complication after chemotherapy that can damage the sensory, motor, autonomic, or cranial nerves in approximately 30%-60% of patients with cancer. CIPN can lead to detrimental dose modifications and/or premature chemotherapy discontinuation due to patient intolerance. The long-term impact of CIPN is particularly challenging and can have a profound impact on the quality of life (QoL) and survivorship. However, this condition is often underdiagnosed. No agents have been established to prevent CIPN. Pre-chemotherapy testing is recommended for high-risk patients. Duloxetine is considered a first-line treatment, whereas gabapentin, pregabalin, tricyclic antidepressants, and topical compounding creams may be used for neuropathic pain control. Home-based, low-to-moderate walking, and resistance exercise during chemotherapy can reduce the severity and prevalence of CIPN symptoms, especially in older patients. Pre-habilitation and rehabilitation should be recommended for all patients receiving cytotoxic chemotherapies. The purpose of this article is to review common chemotherapeutic drugs causing CIPN, risk factors, diagnosis and treatment of CIPN, and evidence of the benefits of rehabilitation.

Physical Activity: A Feasibility Study on Exercise in Men Newly Diagnosed With Prostate Cancer

BACKGROUND

Physical activity (PA) has been shown to improve patient-centered care for cancer-related symptoms, treatment-related side effects, and health-related quality of life.

OBJECTIVES

This feasibility study aimed to explore PA preferences and changes in functional capacity and symptoms during a two-week self-prescribed PA intervention prior to treatment in men newly diagnosed with prostate cancer.

METHODS

Men newly diagnosed with prostate cancer were recruited from a community hospital, part of an academic comprehensive cancer center in the southeastern United States. An individualized PA intervention prescription was developed using baseline measures. Baseline and two-week measures consisted of functional capacity, PA participation, and symptom impact. Descriptive statistics and t tests were used.

FINDINGS

Thirteen men aged an average of 66.14 years (SD = 6.82) participated. Participants significantly improved functional capacity. Most common PAs were walking (n = 9) and yard work (n = 6).

Exercise levels and preferences on exercise counselling and programming among older cancer survivors: A mixed-methods study

OBJECTIVES

To assess exercise levels and exercise counselling /programming preferences among older cancer survivors.

MATERIALS AND METHODS

A mixed-methods study design was employed. Quantitative instruments on exercise levels, exercise counselling and programming preferences, frailty status, and cancer-related symptoms were administered to 290 post-treatment older cancer survivors aged ≥65. Twelve participants with different exercise levels and different views on exercise counselling and programming were purposively selected to participate in semi-structured interviews.

RESULTS

Overall, 58.3% of participants did not meet the recommended exercise guidelines, and 44.1% were not engaging in any vigorous or moderate exercise. Frail survivors were less likely to meet the guidelines (aOR = 0.194, 95%CI = 0.053, 0.712) compared to their robust counterparts. However, 66.9% and 62.8% of participants expressed a definite or possible interest in receiving exercise counselling and participating in an exercise program, respectively. Particularly, survivors who are male, did not receive chemotherapy, are less educated, and have higher symptom burden were less likely to show interest. Most preferred low-intensity exercise (59.8%) and wanted to start the exercise program after treatment (68.2%), which differs from the literature on general adult survivors. The major trigger to initiate and maintain exercise behaviors was the benefits of exercise and a common barrier to exercising was lack of time.

CONCLUSION

Most older cancer survivors did not meet the recommended exercise guidelines, but they were open to exercise counselling and programming. Reviewing education on the benefits of exercise is especially important after treatment completion to promote healthy lifestyles.

Neurotoxicity prevention with a multimodal program (ATENTO) prior to cancer treatment versus throughout cancer treatment in women newly diagnosed for breast cancer: Protocol for a randomized clinical trial

A current challenge in breast cancer (BC) patients is how to reduce the side effects of cancer and cancer treatments and prevent a decrease in quality of life (QoL). Neurotoxic side effects, especially from chemotherapy, are present in up to 75% of women with BC, which implies a large impact on QoL. There is a special interest in the preventive possibilities of therapeutic exercise (TE) for these neurological sequelae, and the benefits of TE could be improved when it is combined with vagal activation techniques (VATs). This superiority randomized controlled trial aims to examine the feasibility and efficacy of an 8-week multimodal intervention (ATENTO) based on moderate-vigorous intensity and individualized TE (aerobic and strength exercises) and VAT (myofascial and breathing exercises), on neurotoxicity prevention in women with BC before starting adjuvant chemotherapy (ATENTO-B) versus throughout adjuvant chemotherapy (ATENTO-T). A sample of 56 women newly diagnosed with BC, as calculated with a power of 85%, will be randomly allocated into these two groups. This study could provide an impetus for the introduction of early multimodal intervention methods to prevent neurotoxicity and consequently avoid the QoL deterioration that BC patients presently suffer throughout their treatments.

Attenuating Treatment-Related Cardiotoxicity in Women Recently Diagnosed With Breast Cancer via a Tailored Therapeutic Exercise Program: Protocol of the ATOPE Trial

OBJECTIVE

Therapeutic exercise is already used to ameliorate some of the side effects of cancer treatment. Recent studies examined its preventive potential regarding treatment-related toxicity, which can increase the risk of functional decline and lead to disease recurrence and death. This trial will examine whether the Tailored Therapeutic Exercise and Recovery Strategies (ATOPE) program, performed before treatment, can mitigate the onset and extent of cardiotoxicity beyond that achieved when the program is followed during treatment in recently diagnosed breast cancer patients.

METHODS

The intervention has a preparatory phase plus 12 to 18 sessions of tailored, high-intensity exercise, and post-exercise recovery strategies. A total of 120 women recently diagnosed with breast cancer, at risk of cardiotoxicity due to anticancer treatment awaiting surgery followed by chemotherapy and/or radiotherapy, will be randomized to either group. In a feasibility study, measurements related to recruitment rate, satisfaction with the program, adherence to them, the retention of participants, safety, and adverse effects will be explored. In the main trial, the efficacy of these interventions will be examined. The major outcome will be cardiotoxicity, assessed echocardiographically via the left ventricular ejection fraction. Other clinical, physical, and anthropometric outcomes and biological and hormonal variables will also be assessed after diagnosis, after treatment, 1 year after treatment ends, and 3 years after treatment ends.

CONCLUSION

Given its potential effect on patient survival, the mitigation of cardiotoxicity is a priority, and physical therapists have an important role in this mitigation. If the ATOPE intervention performed before treatment returns better cardioprotection results, it may be recommendable that patients recently diagnosed follow this program.

IMPACT

The ATOPE program will highlight the need for a physical therapist intervention from the moment of diagnosis, in the prevention or mitigation of cardiotoxicity, in women with breast cancer. It could help physical therapists to establish an adequate therapeutic exercise dose adapted to breast cancer patients and to propose correct therapeutic exercise prescription according to the assimilation of the sessions.

Multiphasic Prehabilitation Across the Cancer Continuum: A Narrative Review and Conceptual Framework

The field of cancer survivorship has significantly advanced person-centered care throughout the cancer continuum. Within cancer survivorship, the last decade has seen remarkable growth in the investigation of prehabilitation comprising pre-treatment interventions to prevent or attenuate the burden of oncologic therapies. While the majority of evidence remains in the surgical setting, prehabilitation is being adapted to target modifiable risk factors that predict poor treatment outcomes in patients receiving other systemic and localized anti-tumor treatments. Here, we propose a multiphasic approach for prehabilitation across the cancer continuum, as a conceptual framework, to encompass the variability in cancer treatment experiences while adopting the most inclusive definition of the cancer survivor.

Prehabilitation is the Gateway to Better Functional Outcomes for Individuals with Cancer

Prehabilitation is a clinical model that introduces components of rehabilitation to patients prior to undergoing intensive medical interventions, such as surgery, in order to optimize function and improve tolerability to the intervention. Cancer care introduces a continuum of sequential or concurrent intensive anti-neoplastic medical interventions that are known to be detrimental to a patient's function. Prehabilitation evidence has grown across several areas of oncology care delivery demonstrating that a multi-modal rehabilitative intervention, delivered prior to oncology-direct therapies, leads to better functional outcomes and improves important endpoints associated with surgery and cancer treatment. This commentary article provides a brief history of the emergence of prehabilitation in cancer care delivery, reviews the current evidence base and guidelines for prehabilitation, and offers insights for future implementation of this model as a standard in oncology care. A prehabilitation program is an optimal starting point for most patients undergoing anti-neoplastic therapy as it serves as a gateway to improving functional outcomes throughout the cancer continuum. Future research in prehabilitation should aim to reach beyond measuring functional outcomes and to explore the impact of this model on important disease treatment endpoints such as tumor response to oncology-directed treatment, impact on treatment-related toxicities, and disease progression.

The Feasibility of Prehabilitation as Part of the Breast Cancer Treatment Pathway

Background

There is compelling support for implementing prehabilitation to optimize perioperative risk factors and to improve postoperative outcomes. However, there is limited evidence studying the application of multimodal prehabilitation for patients with breast cancer.

Objective

To determine the feasibility of multimodal prehabilitation as part of the breast cancer treatment pathway.

Design

This was a prospective, cohort observational study. Breast cancer patients undergoing surgery were recruited. They were assigned to an intervention or control group according to patient preference.

Setting

UK prehabilitation center.

Participants

A total of 75 patients were referred during the study period. Forty eight patients (64%) did not participate; 20 of those opted to be in the control group. Twenty four patients engaged with prehabilitation and returned completed questionnaires. In total, 44 patients were included in the analysis.

Interventions

The program consisted of supervised exercise, nutritional advice, smoking cessation, and psychosocial support.

Outcome Measures

Feasibility was determined by the center's ability to deliver the program. This was measured by the number of patients who wanted to access the service, compared with those able to. Service uptake, patient satisfaction, and project costs were recorded. Patient‐reported outcomes (PROs) and the use of healthcare resources were also evaluated.

Results

A total of 61 patients (81%) wanted to participate; 24 (32%) were able to partake and return questionnaires. Reasons for nonparticipation included surgery within weeks, full‐time commitments, and transportation difficulties. A total of 25 (93%) prehabilitation patients recorded high satisfaction with the program. There was a significant reduction in anxiety among prehabilitation patients. There were no significant improvements in the other PROs. There were no changes to hospital length of stay, readmissions, and complications.

Conclusions

Multimodal prehabilitation is a feasible intervention. Logistical challenges need to be addressed to improve engagement. These results are limited and would require a larger sample to confirm the findings. Work on a thorough cost‐benefit analysis is also required.

Third-Variable Effects: Tools to Understand Who, When, Why, and How Patients Benefit From Surgical Prehabilitation

Prehabilitation is a new field of research that aims to optimize modifiable surgical risk factors before surgery to improve patient-oriented outcomes preoperatively and postoperatively. As with any new intervention, the pressing questions that arise include what interventions work, for whom they work, and when do they work best? Given that prehabilitation can be resource intensive, and that preoperative patient characteristics are likely to produce variation in response to treatment, establishing answers to these questions is critical for successful implementation of prehabilitation in clinical practice. The objective of this review article is to describe the illuminating potential of including "third-variable effects" into the integration of research design; by planning for and including measurements of mediators, moderators, and confounders in the design and analysis of prehabilitation research, we can begin to answer practical, clinically relevant questions.

Feasibility of Prehabilitation Prior to Breast Cancer Surgery: A Mixed-Methods Study

Background

Breast cancer surgery results in numerous acute and long-term adverse outcomes; the degree to which these can be mitigated or prevented through prehabilitation is unknown.

Methods

We conducted a longitudinal, single-arm, mixed-methods study to examine the feasibility of prehabilitation in 22 women undergoing breast cancer surgery. All participants received an individualized exercise prescription including upper quadrant-specific resistance and mobility training and aerobic exercise for the duration of their surgical wait time. Feasibility was assessed by recruitment, adherence, attrition, and intervention-related adverse event rates. An exploratory investigation of intervention efficacy was conducted via a 6-min walk test, upper-quadrant strength and range of motion, volumetric chances associated with lymphedema, and participant-reported quality of life, fatigue, pain, and disability. Outcome assessments were conducted at baseline, prior to surgery, and at six and 12 weeks after surgery. Semi-structured interviews with a subset of participants (n = 5) and health-care providers (H; n = 2) were conducted to provide further insights about intervention feasibility. Qualitative data were analyzed using a hybrid inductive and deductive thematic analysis approach.

Results

Recruitment and attrition rates were 62 and 36%, respectively. Average prehabilitation duration was 31 days (range = 7–69 days). Seventy six percent of participants complied with at least 70% of their prehabilitation prescription. There was a clinically significant increase in the 6-min walk distance from baseline to the preoperative assessment (57 m, 95% CI = −7.52, 121.7). The interviews revealed that the intervention was favorably received by participants and HCPs and included suggestions that prehabilitation (i) should be offered to all surgical candidates, (ii) is an avenue to regain control in the preoperative period, (iii) is a facilitator of postoperative recovery, and (iv) is an opportunity to provide education regarding postoperative rehabilitation protocols. A preference for multimodal prehabilitation (including dietetic and psychological counseling) was also highlighted.

Conclusion

Our findings suggest that surgical prehabilitation in women with breast cancer is feasible. Data are hampered by study sample size and lack of a control group. Thus, randomized controlled trials to examine prehabilitation efficacy in people with breast cancer, especially interventions employing a multimodal strategy, are warranted.

Pain Management in Breast Surgery: Recommendations of a Multidisciplinary Expert Panel-The American Society of Breast Surgeons

Opioid overdose accounted for more than 47,000 deaths in the United States in 2018. The risk of new persistent opioid use following breast cancer surgery is significant, with up to 10% of patients continuing to fill opioid prescriptions one year after surgery. Over prescription of opioids is far too common. A recent study suggested that up to 80% of patients receiving a prescription for opioids post-operatively do not need them (either do not fill the prescription or do not use the medication). In order to address this important issue, The American Society of Breast Surgeons empaneled an inter-disciplinary committee to develop a consensus statement on pain control for patients undergoing breast surgery. Representatives were nominated by the American College of Surgeons, the Society of Surgical Oncology, The American Society of Plastic Surgeons, and The American Society of Anesthesiologists. A broad literature review followed by a more focused review was performed by the inter-disciplinary panel which was comprised of 14 experts in the fields of breast surgery, anesthesiology, plastic surgery, rehabilitation medicine, and addiction medicine. Through a process of multiple revisions, a consensus was developed, resulting in the outline for decreased opioid use in patients undergoing breast surgery presented in this manuscript. The final document was reviewed and approved by the Board of Directors of the American Society of Breast Surgeons.

Network-Based Approach to Identify the Antiproliferative Mechanisms of Bruceine D in Breast Cancer From the Cancer Genome Atlas

Bruceine D (BD) is a natural compound extracted from a Chinese herb Brucea javanica that has been used for anti-inflammatory and anti-cancer treatment. However, little is reported about BD's effects in breast cancer tumorigenesis. In this paper, we aimed to investigate the effect of BD in breast cancer and elucidate the potential mechanism of BD by integrated multiple databases. Our data suggested BD inhibited MCF-7 and MDA-MB-231 cells proliferation and promoted cells apoptosis. We integrated multiple bioinformatics analysis strategies to identify genes, hub modules and pathways associated with BD treatment. Three key pathways, including AMIT_SERUM_RESPONSE_40_MCF10A, BILD_HRAS_ONCOGENIC_SIGNATURE, and NAGASHIMA_NRG1_SIGNALING_UP were identified to be associated with therapeutic effects of BD in breast cancer. Additionally, we validated the key genes by using quantitative real-time PCR and western blot. In conclusion, these findings revealed potential molecular mechanisms of BD to treat breast cancer by affecting AMIT_SERUM_RESPONSE_40_MCF10A, BILD_HRAS_ONCOGENIC_SIGNATURE, and NAGASHIMA_NRG1_SIGNALING_UP pathways and regulating expression of ZFP36, EGR1, and FOS.

Clinically Integrated Physical Therapist Practice in Cancer Care: A New Comprehensive Approach

Best practice recommendations in cancer care increasingly call for integrated rehabilitation services to address physical impairments and disability. These recommendations have languished primarily due to a lack of pragmatic, generalizable intervention models. This perspective paper proposes a clinically integrated physical therapist (CI-PT) model that enables flexible and scalable services for screening, triage, and intervention addressing functional mobility. The model is based on (1) a CI-PT embedded in cancer care provider clinics, and (2) rehabilitation across the care continuum determined by the patient's level of functional mobility. The CI-PT model includes regular screening of functional mobility in provider clinics via a patient-reported mobility measure-the Activity Measure for Post-Acute Care, a brief physical therapy evaluation tailored to the specific functional needs of the individual-and a tailored, skilled physical therapist intervention based on functional level. The CI-PT model provides a pragmatic, barrier-free, patient-centric, data-driven approach to integrating rehabilitation as part of standard care for survivors of cancer. The model standardizes CI-PT practice and may be sufficiently agile to provide targeted interventions in widely varying cancer settings and populations. Therefore, it may be ideal for wide implementation among outpatient oncological settings. Implementation of this model requires a shared approach to care that includes physical therapists, rehabilitation administrators, cancer care providers, and cancer center administrators.

The Role and Scope of Prehabilitation in Cancer Care

OBJECTIVES

To recognize cancer prehabilitation as a pretreatment regimen to increase functional status for patients requiring cancer treatment. This article presents current evidence addressing the efficacy and benefits of prehabilitation regimens in different cancer survivor populations.

DATA SOURCES

Studies and case reports in the PubMed database.

CONCLUSION

Cancer prehabilitation may improve outcomes. Prehabilitation may include targeted or whole-body exercise, nutrition, education, psychologic counseling, and smoking cessation. Opportunities exist to further improve access to and delivery of multimodal prehabilitation, and nurses play a critical role in connecting patients to these services.

IMPLICATIONS FOR NURSING PRACTICE

Oncology nurses who are knowledgeable of cancer treatment-related effects are poised to assess survivors for existing impairments, advocate for prehabilitation for existing and potential morbidities, and monitor functional status over time. As patient educators, they are key to informing cancer survivors about the role of prehabilitation.

Nutrition Education Services Described on National Cancer Institute (NCI)-Designated Cancer Center Websites

For women diagnosed with breast cancer, healthy weight and enhanced nutrition may improve outcomes. The goal of this study is to examine the nutrition education services available on National Cancer Institute (NCI)-Designated Cancer Centers' websites. In 2017, websites of all 61 NCI-Designated Cancer Centers that provide adult clinical care were reviewed at least twice. Websites were analyzed for the existence and type of expert-directed nutrition education services for breast cancer survivors. Of the 61 websites analyzed, 49 (80%) provided information about nutrition education. Twenty (33%) included only nutrition counseling, three (5%) only nutrition classes, and 26 (42%) both counseling and classes. Forty-six websites included information about nutrition counseling; of these, 39 had an easily identifiable description. Thirty-seven class options were offered, 22% were specific to breast cancer, 16% to subgroups such as young women, 41% were nutrition-only classes, and 24% included skills education. Nutrition services are an important part of breast cancer treatment. This study demonstrated that most NCI-designated cancer centers offered counseling. However, the type of information that was offered varied and services were not always specific to patients with breast cancer. Further research is needed to confirm the presence of services, assess patient access, and demonstrate their efficacy in promoting optimal survivor outcomes.

Differentially expressed gene profile and relevant pathways of the traditional Chinese medicine cinobufotalin on MCF‑7 breast cancer cells

Cinobufotalin is a chemical compound extracted from the skin of dried bufo toads that may have curative potential for certain malignancies through different mechanisms; however, these mechanisms remain unexplored in breast cancer. The aim of the present study was to investigate the antitumor mechanism of cinobufotalin in breast cancer by using microarray data and in silico analysis. The microarray data set GSE85871, in which cinobufotalin exerted influences on the MCF‑7 breast cancer cells, was acquired from the Gene Expression Omnibus database, and the differentially expressed genes (DEGs) were analyzed. Subsequently, protein interaction analysis was conducted, which clarified the clinical significance of core genes, and Gene Ontology and Kyoto Encyclopedia of Genes and Genomes were used to analyze cinobufotalin‑related pathways. The Connectivity Map (CMAP) database was used to select existing compounds that exhibited curative properties similar to those of cinobufotalin. A total of 1,237 DEGs were identified from breast cancer cells that were treated with cinobufotalin. Two core genes, SRC proto‑oncogene non‑receptor tyrosine kinase and cyclin‑dependent kinase inhibitor 2A, were identified as serving a vital role in the onset and development of breast cancer, and their expression levels were markedly reduced following cinobufotalin treatment as detected by the microarray of GSE85871. It also was revealed that the 'neuroactive ligand‑receptor interaction' and 'calcium signaling' pathways may be crucial for cinobufotalin to perform its functions in breast cancer. Conducting a matching search in CMAP, miconazole and cinobufotalin were indicated to possessed similar molecular mechanisms. In conclusion, cinobufotalin may serve as an effective compound for the treatment of a subtype of breast cancer that is triple positive for the presence of estrogen, progesterone and human epidermal growth factor receptor‑2 receptors, and its mechanism may be related to different pathways. In addition, cinobufotalin is likely to exert its antitumor influences in a similar way as miconazole in MCF‑7 cells.

The effect of preoperative exercise on upper extremity recovery following breast cancer surgery: a systematic review

Prehabilitation benefits among patients undergoing various oncological surgeries have been demonstrated. However, the effects of presurgical exercise and fitness on postoperative ipsilateral upper extremity recovery outcomes in patients with breast cancer surgery are less evident. A systematic review was performed to assess the effects of preoperative exercise and fitness on postmastectomy recovery. Systematic literature search was performed in 12 electronic databases. Study eligibility was accessed using the PICOS (Participants, Interventions, Comparison, Outcome and Study Design) criteria. Six eligible studies were found: three cohort-control and three prospective observational studies. One randomized-controlled trial showed that prehabilitation was beneficial in shoulder range of motion (ROM) and upper extremity functional recovery. One cohort-control study demonstrated that preoperative exercises reduced postoperative pain without increasing the risk of developing a seroma. A prospective cohort study showed that preoperatively active individuals had a significantly better chance of feeling recovered physically at 3 weeks after surgery. Baseline ipsilateral grip strength, shoulder flexion, and abduction ROM were reliable predictors of shoulder flexion and abduction ROM and grip strength improvements at 1 month following breast cancer surgery. One study showed that preoperative conditioning alone without postoperative rehabilitation was insufficient to aid recovery. Implementing exercise program and optimizing preoperative fitness, especially shoulder ROM, before breast cancer surgery in conjunction with individualized rehabilitation program may benefit postmastectomy ipsilateral upper extremity recovery.
