Cancer prehabilitation and its role in improving health outcomes and reducing health care costs

Occupational therapy rehabilitation for sarcoma patients following limb salvage surgery: a scoping review

Introduction: Sarcomas are rare cancers of bone and soft tissue, and limb salvage surgery is the standard treatment followed by multidisciplinary rehabilitation. The scoping review aimed to summarize the evidence for occupational therapy intervention for adult sarcoma patients following limb salvage surgery.Methods: A review of the literature using a scoping framework was undertaken starting with a systematic database search, followed by an analysis of the literature. The literature was described using a numerical analysis, and the following headings; (a) rehabilitation, (b) activity limitations and participation restrictions, (c) functional outcomes.Findings: Seventeen articles met the review criteria, papers were diverse in study location, type, population, methods and outcomes used. Following limb salvage surgery patients experience functional deficits, activity limitations and participation restrictions in life roles and loss of previous identity. Prehabilitation can influence functional outcomes. Functional activity was found to plateau at 4-12 months following limb salvage surgery, with some patients identifying a need for further rehabilitation.Conclusion: The review identified limited evidence guiding occupational therapy practice for sarcoma patients following limb salvage surgery. Further research is needed to demonstrate the effectiveness of occupational therapy intervention in the early and late stages of rehabilitation and develop evidence based guidelines.Implications for rehabilitationSarcoma patients experience activity limitations and participation restrictions in activities of daily living, work and leisure following limb salvage surgery.Prehabilitation and early intervention can influence functional outcomes.Functional ability may plateau at 4-12 months following limb salvage surgery.Some groups of patients will benefit from late rehabilitation to maximize their rehabilitation potential.

Prehabilitation for adults diagnosed with cancer: A systematic review of long-term physical function, nutrition and patient-reported outcomes

OBJECTIVE

Prehabilitation is increasingly being used to mitigate treatment-related complications and enhance recovery. An individual's state of health at diagnosis, including obesity, physical fitness and comorbidities, are influencing factors for the occurrence of adverse effects. This review explores whether prehabilitation works in improving health outcomes at or beyond the initial 30 days post-treatment and considers the utility of prehabilitation before cancer treatment.

METHODS

A database search was conducted for articles published with prehabilitation as a pre-cancer treatment intervention between 2009 and 2017. Studies with no 30 days post-treatment data were excluded. Outcomes post-prehabilitation were extracted for physical function, nutrition and patient-reported outcomes.

RESULTS

Sixteen randomised controlled trials with a combined 2017 participants and six observational studies with 289 participants were included. Prehabilitation interventions provided multi-modality components including exercise, nutrition and psychoeducational aspects. Prehabilitation improved gait, cardiopulmonary function, urinary continence, lung function and mood 30 days post-treatment but was not consistent across studies.

CONCLUSION

When combined with rehabilitation, greater benefits were seen in 30-day gait and physical functioning compared to prehabilitation alone. Large-scale randomised studies are required to translate what is already known from feasibility studies to improve overall health and increase long-term cancer patient outcomes.

Follow the trail: Using insights from the growth of palliative care to propose a roadmap for cancer rehabilitation

Despite research explicating the benefits of cancer rehabilitation interventions to optimize physical, social, emotional, and vocational functioning, many reports document low rates of referral to and uptake of rehabilitation in oncology. Cancer rehabilitation clinicians, researchers, and policy makers could learn from the multidisciplinary specialty of palliative care, which has benefited from a growth strategy and has garnered national recognition as an important and necessary aspect of oncology care. The purpose of this article is to explore the actions that have increased the uptake and integration of palliative care to yield insights and multimodal strategies for the development and growth of cancer rehabilitation. After examining the history of palliative care and its growth, the authors highlight 5 key strategies that may benefit the field of cancer rehabilitation: 1) stimulating the science in specific gap areas; 2) creating clinical practice guidelines; 3) building clinical capacity; 4) ascertaining and responding to public opinion; and 5) advocating for public policy change. Coordinated and simultaneous advances on these 5 strategies may catalyze the growth, utilization, and effectiveness of patient screening, timely referrals, and delivery of appropriate cancer rehabilitation care that reduces disability and improves quality of life for cancer survivors who need these services.

Contemporary Opportunity for Prehabilitation as Part of an Enhanced Recovery after Surgery Pathway in Colorectal Surgery

The implementation of upfront, preoperative habilitation ("prehabilitation"), as opposed to postoperative habilitation (rehabilitation), provides a unique opportunity to optimize surgical outcomes, while ensuring that patients receive necessary conditioning that may otherwise be significantly delayed by postoperative complications. In this review, opportunities to design, implement, monitor, and evaluate a surgical prehabilitation program in colorectal surgery are discussed, and broken down to include emotional, physical, and nutritional aspects of care in the preoperative setting.

High-intensity interval training in the therapy and aftercare of cancer patients: a systematic review with meta-analysis

PURPOSE

This review and meta-analysis aimed to evaluate the effects of high-intensity interval training (HIIT) compared to usual care (UC) or moderate-intensity training (MIE) on physical fitness and health-related outcomes in cancer patients across all stages of therapy and aftercare.

METHODS

Databases were systematically searched in accordance with the PRISMA guidelines until October 4th, 2018. Eligibility criteria included adult patients of various cancer types, performing HIIT vs. UC or MIE. Outcomes of interest included physical fitness (cardiorespiratory fitness [VO_2peak] and functional capacity) and health-related outcomes (body composition, quality of life, cancer-related fatigue, and blood-borne biomarkers). Mean differences (MD) were calculated and pooled to generate effect sizes for VO_2peak.

RESULTS

The search identified 1453 studies, out of which 12 articles were included. The average duration of interventions was 6.7 ± 3.0 weeks, with 2.8 ± 0.5 sessions per week. The meta-analysis for VO_2peak showed superiority of HIIT compared to UC (MD 3.73; 95% CI 2.07, 5.39; p < 0.001) but not MIE (MD 1.36; 95% CI - 1.62, 4.35; p = 0.370). Similarly, no superior effects of HIIT compared to MIE were found for quality of life or changes in lean mass, while evidence was provided for a larger reduction in fat mass.

CONCLUSION

This systematic review showed that short-term HIIT induces similar positive effects on physical fitness and health-related outcomes as MIE but seems to be superior compared to UC. Thus, HIIT might be a time-efficient intervention for cancer patients across all stages of therapy and aftercare.

IMPLICATIONS FOR CANCER SURVIVORS

High-intensity interval training (HIIT) is superior compared to usucal care in improving physical fitness and health-related outcomes in cancer patients across all stages of therapy and aftercare. Currently, there is no evidence for the benefits of HIIT compared to aerobic training of moderate intensity (MIE) for changes in cardiorespiratory fitness, lean mass and patient-reported outcomes. Reductions in fat mass may be more pronounced in HIIT compared to MIE when training is performed in aftercare.

Symptom-based interventions to promote quality survivorship

Survival alone is no longer an adequate outcome for persons with brain tumors; the quality of the survivorship experience should be viewed with equal importance. Symptom management is a significant component of quality survivorship care. Regardless of their histology, brain tumors and therapies used to treat them produce symptoms that affect an individual's ability to function in everyday life. Common symptoms include fatigue, cognitive impairment, distress, and sleep disturbance. Symptom-based interventions for persons with brain tumors focus on prevention, self-management, and prescriptive interventions targeted to these problems. Unfortunately, little evidence exists to support many interventions, making it challenging for clinicians to provide concrete recommendations. Research is needed to provide evidence in support of symptom-based interventions while novel approaches to these challenging problems are developed.

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.

Physical activity and exercise during preoperative pancreatic cancer treatment

PURPOSE

Guidelines recommend exercise to cancer survivors, but limited data exists regarding exercise among patients undergoing preoperative cancer treatment. We examined differences in weekly self-reported exercise and accelerometer-measured physical activity among participants in a home-based exercise program administered during preoperative treatment for pancreatic cancer.

METHODS

Participants were encouraged to perform at least 60 min/week of moderate-intensity aerobic exercise and at least 60 min/week of full-body strengthening exercises concurrent with chemotherapy, chemoradiation therapy or both sequentially and received resistance equipment, program instruction, and biweekly follow-up calls to encourage adherence. Self-reported aerobic and strengthening exercise minutes were measured using daily logs, and physical activity was measured objectively using accelerometers.

RESULTS

Fifty participants (48% female, mean age 66 ± 8 years) participated for an average of 16 ± 9 preoperative weeks. Participants reported overall means of 126 ± 83 weekly minutes of aerobic exercise and 39 ± 33 weekly minutes of strengthening exercise in daily logs. Participants performed 158.7 ± 146.7 weekly minutes of accelerometer-measured moderate-to-vigorous physical activity. There were no significant differences in exercise or physical activity between treatment phases.

CONCLUSIONS

These findings suggest that it is feasible to target the entire preoperative course for exercise prescription. Although participants exceeded aerobic exercise recommendations on average, we observed low strengthening exercise adherence and wide variability in self-reported exercise and accelerometer physical activity variables. These findings suggest that additional support, including program adaptations, may be necessary to overcome barriers to exercise or improve motivation when prescribing exercise in this clinical scenario.

Balance and Gait Impairment: Sensor-Based Assessment for Patients With Peripheral Neuropathy

BACKGROUND

Individuals with peripheral neuropathy (PN) frequently experience balance and gait impairments that can lead to poor physical function, falls, and injury. Nurses are aware that patients with cancer experience balance and gait impairments but are unsure of optimal assessment and management strategies.

OBJECTIVES

This article reviews options for balance and gait assessment for patients diagnosed with cancer experiencing PN, describes advantages and limitations of the various options, and highlights innovative, clinically feasible technologies to improve clinical assessment and management.

METHODS

The literature was reviewed to identify and assess the gold standard quantitative measures for assessing balance and gait.

FINDINGS

Gold standard quantitative measures are burdensome for patients and not often used in clinical practice. Sensor-based technologies improve balance and gait assessment options by calculating precise impairment measures during performance of simple clinical tests at the point of care.

Older Age, Early Symptoms and Physical Function are Associated with the Severity of Late Symptom Clusters for Men Undergoing Radiotherapy for Prostate Cancer

AIMS

To identify symptom clusters and predisposing factors associated with long-term symptoms and health-related quality of life after radiotherapy in men with prostate cancer.

MATERIALS AND METHODS

Patient-reported outcomes (PROs) data from the Medical Research Council RT01 radiotherapy with neoadjuvant androgen deprivation therapy trial of 843 patients were used. PROs were collected over 5 years with the University of California, Los Angeles Prostate Cancer Index (UCLA-PCI) and the 36 item Short-Form Health Survey (SF-36). Symptom clusters were explored using hierarchical cluster analysis. The association of treatment dose, baseline patient characteristics and early symptom clusters with the change in severity of PROs over 3 years was investigated with multivariate linear mixed effects models.

RESULTS

Seven symptom clusters of three or more symptoms were identified. The clusters were stable over time. The longitudinal profiles of symptom clusters showed the onset of acute symptoms during treatment for all symptom clusters and significant recovery by 6 months. Some clusters, such as physical health and sexual function, were adversely affected more than others by androgen deprivation therapy, and were less likely to return to pretreatment levels over time. Older age was significantly associated with decreased long-term physical function, physical health and sexual function (P < 0.001). Both baseline and acute symptom clusters were significant antecedents for impaired function and health-related quality of life at 3 years.

CONCLUSIONS

Men with poorer physical function and health before or during treatment were more likely to report poorer PROs at year 3. Early assessment using PROs and lifestyle interventions should be used to identify those with higher needs and provide targeted rehabilitation and symptom management.

Role of the Speech-Language Pathologist (SLP) in the Head and Neck Cancer Team

While treatments for head and neck cancer are aimed at curing patients from disease, they can have significant short- and long-term negative impacts on speech and swallowing functions. Research demonstrates that early and frequent involvement of Speech-Language Pathologists (SLPs) is beneficial to these functions and overall quality of life for head and neck cancer patients. Strategies and tools to optimize communication and safe swallowing are presented in this chapter.

Exercise program design considerations for head and neck cancer survivors

The present study aimed to establish exercise preferences, barriers, and perceived benefits among head and neck cancer survivors, as well as their level of interest in participating in an exercise program. Patients treated for primary squamous cell carcinoma of the head and neck between 2010 and 2014 were identified from the hospital database and sent a postal questionnaire pack to establish exercise preferences, barriers, perceived benefits, current physical activity levels, and quality of life. A postal reminder was sent to non-responders 4 weeks later. The survey comprised 1021 eligible patients of which 437 (43%) responded [74% male, median (interquartile range) age, 66 (60-73) years]. Of the respondents, 30% said 'Yes' they would be interested in participating in an exercise program and 34% said 'Maybe'. The most common exercise preferences were a frequency of three times per week, moderate-intensity, and 15-29 min per bout. The most popular exercise types were walking (68%), flexibility exercises (35%), water activites/swimming (33%), cycling (31%), and weight machines (19%). Home (55%), outdoors (46%) and health club/gym (33%) were the most common preferred choices for where to regularly exercise. Percieved exercise benefits relating to improved physical attributes were commonly cited, whereas potential social and work-related benefits were less well-acknowledged. The most commonly cited exercise barriers were dry mouth or throat (40%), fatigue (37%), shortness of breath (30%), muscle weakness (28%) difficulty swallowing (25%), and shoulder weakness and pain (24%). The present findings inform the design of exercise programs for head and neck cancer survivors.

Feasibility of Presurgical Exercise in Men With Prostate Cancer Undergoing Prostatectomy

BACKGROUND

Prostatectomy is associated with short- and long-term morbidity, which includes attenuation of muscle function and deterioration of lean body mass. Physical function is a known predictor of morbidity and mortality, with initial evidence indicating that presurgical exercise is associated with fewer postsurgical complications and shorter hospitalization. The aim was to determine the feasibility of a supervised presurgical exercise program for prostate cancer (PCa) patients scheduled for prostatectomy.

METHODS

Ten men (68+6.4 years old) with localized PCa undertook a 6-week resistance and aerobic exercise program prior surgery. Training was undertaken twice weekly and patients were assessed at baseline, presurgery, and 6 weeks postsurgery. Outcome measures included muscle and physical performance, body composition, urinary incontinence and questionnaire.

RESULTS

Muscle strength increased by 7.5% to 24.3% ( P < .05) from baseline to presurgery but decreased to pretraining levels postsurgery, except for knee extensor strength ( P = .247). There were significant improvements ( P < .05) in the 6-m fast walk (9.3%), 400-m walk (7.4%), and chair rise (12.3%) at presurgery. Following surgery, improvements in physical performance were maintained. There was no change in lean or fat mass prior to surgery, but lean mass declined by 2.7 kg ( P = .014) following surgery. There were no adverse effects from the exercise program.

CONCLUSIONS

Exercise undertaken prior to prostatectomy improved muscle and physical performance, with functional benefits maintained 6 weeks postsurgery. Presurgical exercise for PCa patients has the potential to facilitate recovery by improving physical reserve capacity, especially in men with poor muscle nd physical performance.

The short-term impact of colorectal cancer treatment on physical activity, functional status and quality of life: a systematic review

BACKGROUND

Physical activity, functional status and quality of life (QoL) are important determinants of the quality of life (QoL) after colorectal cancer (CRC) treatment; however, little is known on how the treatment impacts these outcomes. Having this understanding could help clinicians develop and implement strategies that would enhance or maintain the QoL of CRC patients.

OBJECTIVES

To identify the impact of curative CRC treatment (surgery with or without radiotherapy and/or chemotherapy) on physical activity, functional status and QoL within one year of treatment or diagnosis.

INCLUSION CRITERIA TYPES OF PARTICIPANTS

Colorectal cancer survivors aged 18 years and over.

TYPES OF INTERVENTIONS

Curative CRC treatment, which was surgery with or without radiotherapy and/or chemotherapy.

TYPES OF STUDIES

Pre- and post-observational and experimental studies.

OUTCOMES

Physical activity, ability to perform activities of daily living (functional status) and QoL.

SEARCH STRATEGY

CINAHL, Embase, MEDLINE, OpenGrey and ProQuest Dissertations and Theses were used to obtain published and unpublished studies in English. The date range was the start of indexing to February 2015.

METHODOLOGICAL QUALITY

All studies were assessed independently by two reviewers for relevance, eligibility and methodological quality.

DATA EXTRACTION

Data from included papers were extracted using a modified data extraction tool. Data that were presented graphically were extracted using online software.

DATA SYNTHESIS

The differences between postoperative and baseline values were calculated using the Review Manager 5.3.5 (Copenhagen: The Nordic Cochrane Centre, Cochrane) calculator and expressed as mean difference and their corresponding 95% confidence interval. Where possible, study results were pooled in statistical meta-analysis. The physical activity, functional status and some QoL results are presented in a narrative and table form.

RESULTS

A total of 23 studies were included in this review: two studies (N = 2019 patients) evaluated physical activity, two studies (N = 6908 patients) assessed functional status and 22 studies (N = 2890 patients) measured QoL. Physical activity was observed to decrease at six months after treatment. The functional status of CRC patients decreased, particularly in the elderly (Summary of findings 1 and 2). As for QoL, only the physical and functional aspects were seen to decline up to six months, but scores almost returned to baseline levels at one year after treatment. The QoL studies that used the European Organization for Research and Treatment of Cancer QLQ-C30 tool were pooled in statistical meta-analysis and summarized in Summary of findings 2. The results must be interpreted carefully due to the heterogeneity of studies and scarcity of recent studies.

CONCLUSION

In spite of the limitations, it is likely that the physical and functional capacity of CRC survivors deteriorates after treatment.

IMPLICATIONS FOR PRACTICE

The period between diagnosis and treatment provides an opportunity for clinicians to implement interventions (e.g. exercise interventions) that could enhance or restore the physical and functional capacity of CRC survivors.

IMPLICATIONS FOR RESEARCH

The paucity of studies and heterogeneity need to be addressed. The outcomes for colon and rectal cancer survivors, ostomates and non-ostomates must be analyzed separately.

Cancer Prevention in the Survivorship Setting

OBJECTIVES

To describe how nurses can use risk reduction and health promotion activities to facilitate surveillance of late effects and secondary cancers in long-term cancer survivors.

DATA SOURCES

Literature review on survivorship, nursing practice, cancer prevention, and survivorship; articles published in peer-reviewed scientific journals; and Web-based or professional organization resources.

CONCLUSION

Appropriate participation in screening activities, early detection of cancer, and further advances in treatment have contributed to the rise in cancer survivors. A demand for nurses with clinical experience and competence in survivorship care will follow.

IMPLICATIONS FOR NURSING PRACTICE

Oncology nurses have an essential role in providing safe and high-quality care throughout the survivorship experience, which can contribute to better long-term outcomes.

Cancer Prehabilitation for Patients Starting from Active Treatment to Surveillance

The purpose of this brief summary is to introduce the concept of cancer prehabilitation and the role of oncology nurses in prehabilitation care. Cancer prehabilitation has been defined by Sliver and Baima (2013) as "a process on the cancer continuum of care that occurs between the time of cancer diagnosis and the beginning of acute treatment." The evidence supports the notion that prehabilitation programs can improve physical and psychological health outcomes and decrease overall health care costs. The care model for cancer prehabilitation should include timely and efficient assessment throughout the care continuum with a focus on improving outcomes in cancer at every stage. During the cancer journey, three types of assessment with different aims are included: (1) prehabilitation assessment pretreatment, (2) rehabilitation assessment at early post treatment, and (3) health promotion assessment at the end of treatment. Specific prehabilitation assessment and interventions for treatment-related complications or major side-effects should be considered. Teaching, counseling, discharge planning, and coordination should also be part of an oncology nurse's role in cancer prehabilitation. It is suggested that cancer care managers or navigators be trained in the assessment of their patients' physical and psychological status once the cancer diagnosis has been identified and the patient has decided to receive active treatment, especially for those waiting for surgery at home. Oncology nurses could increase their competence with prehabilitation care by gaining knowledge about cancer-related treatments and their outcomes for specific cancers and by strengthening the ability to assess the functional status and psychological distress of their patients.

Psychological effects of androgen-deprivation therapy on men with prostate cancer and their partners

The clinical benefits of androgen-deprivation therapy (ADT) for men with prostate cancer (PC) have been well documented and include living free from the symptoms of metastases for longer periods and improved quality of life. However, ADT comes with a host of its own serious side effects. There is considerable evidence of the adverse cardiovascular, metabolic, and musculoskeletal effects of ADT. Far less has been written about the psychological effects of ADT. This review highlights several adverse psychological effects of ADT. The authors provide evidence for the effect of ADT on men's sexual function, their partner, and their sexual relationship. Evidence of increased emotional lability and depressed mood in men who receive ADT is also presented, and the risk of depression in the patient's partner is discussed. The evidence for adverse cognitive effects with ADT is still emerging but suggests that ADT is associated with impairment in multiple cognitive domains. Finally, the available literature is reviewed on interventions to mitigate the psychological effects of ADT. Across the array of adverse effects, physical exercise appears to have the greatest potential to address the psychological effects of ADT both in men who are receiving ADT and in their partners.
