Factors affecting upper limb functional recovery after mastectomy with immediate breast reconstruction: a prospective study. Physiother Theory Pract 2024:1-11. [PMID: 38616681 DOI: 10.1080/09593985.2024.2343043] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Accepted: 04/08/2024] [Indexed: 04/16/2024]
Abstract
BACKGROUND Little is known about the differences in postoperative shoulder function following two common approaches for immediate breast reconstruction (IBR): abdominal-based breast reconstruction and implant-based breast reconstruction (ABR and IMBR). It was hypothesized that postoperative upper limb function would differ between the ABR and IMBR due to incomplete detachment of the pectoral muscles. PURPOSE This study aimed to investigate the factors for shoulder function recovery post-IBR and compare recovery outcomes between ABR and IMBR. METHODS This single-center prospective follow-up study included 60 patients who underwent IBR for 4 months postoperatively. Patients were invited to complete functional measurements 1 and 4 months postoperatively. The primary outcome was improvement in upper limb disability based on the Q-DASH score. Secondary outcomes were functional shoulder recovery markers: shoulder flexibility, strength, movement accuracy, scapular alignment, body schema accuracy, and neuropathic pain. Repeated-measures analyzes of variance and linear regression were performed. RESULTS Within-group differences were found for most variables (p < .05) except for neuropathic pain (p = .929). However, there was no overall main group effect (p > .05). Multivariate regression analysis established significant models for ABR and IMBR (R2 = 0.430, p = .002 and R2 = 0.442, p < .001, respectively). However, the variables included in the model showed between-group differences. CONCLUSION Postoperative shoulder function was comparable between the two IBR approaches. However, different factors were associated with improved upper limb disability between ABR and IMBR. Acute rehabilitation focused on resolving muscle tightness and pain may help mitigate upper limb disabilities following IBR.Trial registration number: KCT 0006501.

Abstract
Purpose Although exercise is recommended for cancer survivors with chemotherapy-induced peripheral neuropathy (CIPN), the effective types of exercise for preventing and treating CIPN remain unclear. This systematic review and network meta-analysis (NMA) aimed to evaluate the comparative effects of exercise on CIPN. Methods We included relevant randomized controlled trials (RCTs) identified in a 2019 systematic review that evaluated the effects of exercise on CIPN and conducted an additional search for RCTs published until 2023. We evaluated the risk of bias for each RCT; the comparative effectiveness of exercise on patient-reported quality of life (QOL) through an NMA; and the effectiveness of exercise on QOL scores, patient-reported CIPN symptoms, and pain through additional meta-analyses. Results Twelve studies (exercise, n = 540; control, n = 527) comparing 8 exercise interventions were included in the analysis. All studies were determined to have a high risk of bias. The meta-analyses showed significantly improved QOL [standard mean differences (SMD) 0.45; 95% confidence interval (CI) = 0.12 to 0.78] and CIPN symptoms (SMD 0.46; 95% CI = 0.11 to 0.82). No severe adverse events were reported. Pain tended to improve with exercise (SMD 0.84; 95% CI = -0.11 to 1.80). An NMA suggested that the interventions of a combination of balance and strength training showed a significant improvement in QOL scores compared to the control. Conclusion Exercise interventions may be beneficial for improving QOL and CIPN symptoms. High-quality large clinical trials and data are needed to conclude that exercise is beneficial and safe.

Abstract
BACKGROUND Colorectal cancer is one of the most common malignancies worldwide. Oxaliplatin, which is used as adjuvant chemotherapy, affects quality of life by causing oxaliplatin-induced peripheral neuropathy in colorectal cancer patients. OBJECTIVES This study examined the effects of an application (app)-based physical activity program for alleviating peripheral neuropathy symptoms in colorectal cancer patients undergoing chemotherapy. METHODS This was a randomized controlled study that included 34 patients undergoing chemotherapy after being diagnosed with colorectal cancer. Outcomes were compared between patients who participated in a 6-week app-based physical activity program (experimental group; n = 17) and who received standard booklet education (control group; n = 17). Data were collected using questionnaires, and exercise time was recorded to evaluate intervention adherence. RESULTS Significant differences were observed between the groups in peripheral neuropathy symptoms (F = 8.93, P = .002), interference with activities (Z = -2.55, P = .011), and quality of life (F = 7.65, P = .003). The experimental group showed significantly higher average exercise times at 1 to 4 weeks (Z = -2.10, P = .026), 5 to 6 weeks (Z = -4.02, P < .001), and 1 to 6 weeks (Z = -3.40, P = .001) than the control group. CONCLUSIONS The app-based physical activity program had a positive effect on participants' exercise adherence and reduced peripheral neuropathy symptoms. Thus, we propose the adoption of a mobile health app that can be used at any time or place as an intervention for preventing or alleviating adverse effects during the treatment of cancer patients. IMPLICATIONS FOR PRACTICE An app-based physical activity program using the mobile health app can be used as a nursing intervention to manage symptoms and increase the health behavior adherence in cancer patients.

Abstract
OBJECTIVE This study aimed to investigate the impact of 6 wks of at-home sensory-motor exercises on balance and fatigue levels in women with multiple sclerosis, a progressive autoimmune disease affecting the central nervous system. Multiple sclerosis symptoms can significantly reduce quality of life. DESIGN In this quasi-experimental study, 26 female patients with multiple sclerosis aged 20-40 yrs with an expanded disability status scale of 0-4 were randomly assigned to control and experimental groups. The experimental group performed sensory-motor exercises for 6 wks, three sessions a week, and for 1 hr at home. Balance and fatigue were evaluated with Sharpened-Romberg tests (for static balance), a 6-step test of Get-Up and Go (for dynamic balance), and a Fatigue Severity Scale. At the end of the sixth week, these tests were re-evaluated like the pretest stage. RESULTS Experimental group showed better static balance and Fatigue Severity Scale than control group, but no difference in dynamic balance. CONCLUSIONS Considering the outbreak of COVID-19 and the resultant lockdown, the importance of exercise and physical activities in patients with multiple sclerosis, and the positive effects of sensory-motor exercises at home in the present study, these kinds of sensory-motor workouts are highly recommended to improve balance and reduce the fatigue in patients with multiple sclerosis.

Non-pharmacological therapy for chemotherapy-induced peripheral neurotoxicity: a network meta-analysis of randomized controlled trials. BMC Neurol 2023; 23:433. [PMID: 38082216 PMCID: PMC10712106 DOI: 10.1186/s12883-023-03485-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2023] [Accepted: 12/01/2023] [Indexed: 12/18/2023] Open
Abstract
BACKGROUND Chemotherapy-induced peripheral neurotoxicity (CIPN) is the most common adverse effect in patients undergoing chemotherapy, and no effective interventions are currently available for its prevention and treatment. Non-pharmacological therapies appear to be beneficial for the prevention and treatment of CIPN, but it remains unclear which therapy is most effective. The aim of this study was to identify the most effective non-pharmacological therapy for CIPN patients. METHODS PubMed, Web of Science, Embase, and Cochrane Library were searched for randomized controlled trials on non-pharmacological therapies for CIPN. The primary outcomes included pain and peripheral neuropathological symptoms, and the secondary outcomes included quality of life, sensory and motor symptoms. The pairwise analysis and a network meta-analysis were performed using a random effects model. RESULTS A total of 46 articles were included in this study, involving 2,878 participants. Our study showed that massage was more effective in pain-alleviating compared with acupuncture [SMD = 0.81, 95%CI (0.04, 1.57)], vitamin and gabapentin [SMD = 2.56, 95%CI (1.39, 3.74)], and usual care and placebo [SMD = 0.9, 95%CI (0.31, 1.49)]. As for attenuating peripheral neuropathological symptoms, massage was more effective than usual care and placebo [SMD = 0.75, 95%CI (0.33, 1.17)], sensorimotor training [SMD = 1.17, 95%CI (0.24, 2.10)], electrostimulation [SMD=-1.18, 95%CI (-2.14, -0.21)], multimodal exercise [SMD=-0.82, 95%CI (-1.57, -0.08)], and resistance training [SMD = 1.03, 95%CI (0.11, 1.95)]. Massage was also more effective than other non-pharmacological therapies in improving quality of life, sensory and motor symptoms. CONCLUSIONS According to our study, massage has advantages in alleviating pain, improving quality of life, and improving peripheral neuropathological symptoms and has better effect than other non-pharmacological interventions, representing certain clinical significance. However, the results of this study should be interpreted with caution due to the limitations of the included studies. In the future, more high-quality multi arm randomized controlled trials can be attempted to provide direct comparisons of the relative effects of non-pharmacological interventions.

Abstract
Importance Chemotherapy-induced peripheral neuropathy (CIPN), one of the most common and severe adverse effects of chemotherapy, is associated with worse quality of life among survivors of ovarian cancer. Currently, there is no effective treatment for CIPN. Objective To evaluate the effect of a 6-month aerobic exercise intervention vs attention-control on CIPN among women treated for ovarian cancer in the Women's Activity and Lifestyle Study in Connecticut (WALC) to provide evidence to inform the guidelines and recommendations for prevention or treatment of CIPN. Design, Setting, and Participants This prespecified secondary analysis evaluated the Women's Activity and Lifestyle Study in Connecticut (WALC), a multicentered, open-label, population-based, phase 3 randomized clinical trial of an aerobic exercise intervention vs attention control for CIPN in patients who were diagnosed with ovarian cancer. Only WALC participants who received chemotherapy were included in this analysis. Participants were randomized 1:1 to either a 6-month aerobic exercise intervention or to attention control. All analyses were conducted between September 2022 and January 2023. Interventions The exercise intervention consisted of home-based moderate-intensity aerobic exercise facilitated by weekly telephone counseling from an American College of Sports Medicine/American Cancer Society-certified cancer exercise trainer. Attention control involved weekly health education telephone calls from a WALC staff member. Main Outcomes and Measure Change in CIPN was the primary outcome in this secondary analysis. This outcome was represented by CIPN severity, which was self-measured by participants at baseline and 6 months using the Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity scale, with a score range of 0 to 44. A mixed-effects model was used to assess the 6-month change in CIPN between the exercise intervention and attention control arms. Results Of the 134 participants (all females; mean [SD] age, 57.5 [8.3] years) included in the analysis, 69 were in the exercise intervention arm and 65 were in the attention control arm. The mean (SD) time since diagnosis was 1.7 (1.0) years. The mean (SD) baseline CIPN scores were 8.1 (5.6) in the exercise intervention arm and 8.8 (7.9) in the attention control arm (P = .56). At 6 months, the self-reported CIPN score was reduced by 1.3 (95% CI, -2.3 to -0.2) points in the exercise intervention arm compared with an increase of 0.4 (95% CI, -0.8 to 1.5) points in the attention control arm. The between-group difference was -1.6 (95% CI, -3.1 to -0.2) points. The point estimate was larger among the 127 patients with CIPN symptoms at enrollment (-2.0; 95% CI, -3.6 to -0.5 points). Conclusions and Relevance Findings of this secondary analysis of the WALC trial indicate that a 6-month aerobic exercise intervention vs attention control significantly improved self-reported CIPN among patients who were treated for ovarian cancer. While replication of the findings in other studies is warranted, incorporating referrals to exercise programs into standard oncology care could reduce CIPN symptoms and increase quality of life in patients with ovarian cancer.

Initial observations on sexual dysfunction as a symptom of chemotherapy-induced peripheral neuropathy. GERMAN MEDICAL SCIENCE : GMS E-JOURNAL 2023; 21:Doc08. [PMID: 37426888 PMCID: PMC10326524 DOI: 10.3205/000322] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Figures] [Subscribe] [Scholar Register] [Received: 12/16/2021] [Revised: 01/14/2023] [Indexed: 07/11/2023]
Abstract
Introduction Peripheral neuropathy (PNP) in feet and/or hands and sexual dysfunction are common side effects of cancer therapies. In patients with other diseases, there is evidence of an association between peripheral nervous system disorders and sexual dysfunction due to the impact of impaired neuronal control on genital organ sensitivity. In cancer patient interviews, it has now been observed that PNP and sexual dysfunction may be related. The aim of the study was to investigate the potential association between PNP, sexual dysfunction, and physical activity behavior. Methods Ninety-three patients with PNP of the feet and/or hands were interviewed in August/September 2020 in a cross-sectional study regarding medical history, sexual dysfunction and functionality of the genital organs. Results Thirty-one persons who participated in the survey provided seventeen evaluable questionnaires (four men, thirteen women). Nine women (69%) and three men (75%) reported sensory disorders of the genital organs. Three men (75%) had erectile dysfunction. All men who had sensory symptoms of the genital organs received chemotherapy, and one man also received immunotherapy. Eight women were sexually active. Five (63%) of them reported genital organ symptoms and mainly lubrication disorders. Four (80%) of the five sexually inactive women reported genital organ symptoms. Eight of the nine women with sensory symptoms of the genital organs received chemotherapy, and one woman received immunotherapy. Discussion Our limited data suggest genital organ sensory symptoms in chemotherapy and immunotherapy patients. Genital organ symptoms do not appear to be directly related to sexual dysfunction, and the association between PNP and genital organ symptoms appears to be more pronounced in sexually inactive women. Chemotherapy could cause sensory symptoms of the genital organs and sexual dysfunction by damaging genital organ nerve fibers. Chemotherapy and anti-hormone therapy (AHT) could trigger a disturbance of the hormone balance, which in turn could be causative for sexual dysfunction. It remains open whether the cause of these disorders is the symptomatology of the genital organs or the altered hormone balance. The significance of the results is limited due to the small number of cases. To our knowledge, this study is the first of its kind in cancer patients and allows a better understanding of the association between PNP, sensory symptoms of the genital organs, and sexual dysfunction. Conclusion In order to be able to narrow down the cause of these initial observations in cancer patients more precisely, larger studies are needed that can relate the influence of cancer therapy-induced PNP, physical activity level and hormone balance to sensory symptoms of the genital organs and sexual dysfunction. The methodology of further studies should take into account the frequent problem of low response rates in surveys on sexuality.

Abstract
PURPOSE OF REVIEW Chemotherapy-induced peripheral neuropathy (CIPN) is a debilitating and often painful condition that occurs after administration of chemotherapeutic agents. The primary objective of this systematic review was to appraise the literature on conservative, pharmacological, and interventional treatment options for CIPN pain. RECENT FINDINGS There is level I evidence supporting modest to moderate improvement in CIPN pain from duloxetine treatment, as well as short-term modest improvement from physical therapy and acupuncture. Although opioid and cannabis administration may provide short-term modest improvement, administration is commonly limited by side effects. Generally, most studies reported no clinical benefit from yoga, topical neuropathic agents, gabapentinoids, and tricyclic antidepressants. Evidence is currently equivocal for scrambler therapy and transcutaneous electrical nerve stimulation. Finally, evidence on neuromodulation options is limited to mostly case reports/series and one observational study highlighting moderate improvement with auricular nerve stimulation. This systematic review provides an overview of conservative, pharmacologic, and interventional treatment modalities for CIPN pain. Furthermore, it provides a level of evidence and degree of recommendation based on the United States Preventive Services Task Force (USPSTF) criteria for each specific treatment modality.

Abstract
This article discusses chemotherapy-induced peripheral neuropathic pain (CIPNP) and its associated neuropathic pain syndrome that occurs in patients with malignant neoplasms (MN) during cytostatic therapy. The overall prevalence of CIPNP in patients with malignant neoplasms associated with chemotherapy with neurotoxic drugs is estimated, according to various sources, to be about 70%. The pathophysiological mechanisms of CIPNP have not been fully studied, but it is known that they are based on: impaired axonal transport, oxidative stress, induction of apoptosis, DNA damage, dysfunction of voltage-gated ion channels, and central mechanisms. It is important to recognize CIPNP in the clinical symptoms of patients with cancer treated with cytostatics, since these disorders can lead to serious restrictions in the motor, sensory and autonomic functions of the upper and lower extremities, as well as reduce the quality of life and daily functioning of such patients, forcing them to adjust the dose of chemotherapy drugs, transfer the next cycles and even interrupt the treatment of cancer carried out according to vital needs. In addition to the clinical examination, scales and questionnaires have been developed to identify symptoms of CIPNP, but it is most important for neurological and oncological specialists to know and be able to recognize such symptoms in patients. The mandatory research methods for identifying the symptoms of polyneuropathy include electroneuromyography (ENMG), which allows you to assess muscle activity, functional characteristics and the state of the function of peripheral nerves. The methods used to reduce symptoms are screening patients for the development of CIPNP and identifying patients at high risk of CIPNP and, if necessary, reducing the dose or changing cytostatics. Methods for correcting this disorder using different classes of drugs require more detailed study and further research.

Design of a multinational randomized controlled trial to assess the effects of structured and individualized exercise in patients with metastatic breast cancer on fatigue and quality of life: the EFFECT study. Trials 2022; 23:610.

Abstract
Background Many patients with metastatic breast cancer experience cancer- and treatment-related side effects that impair activities of daily living and negatively affect the quality of life. There is a need for interventions that improve quality of life by alleviating fatigue and other side effects during palliative cancer treatment. Beneficial effects of exercise have been observed in the curative setting, but, to date, comparable evidence in patients with metastatic breast cancer is lacking. The aim of this study is to assess the effects of a structured and individualized 9-month exercise intervention in patients with metastatic breast cancer on quality of life, fatigue, and other cancer- and treatment-related side effects. Methods The EFFECT study is a multinational, randomized controlled trial including 350 patients with metastatic breast cancer. Participants are randomly allocated (1:1) to an exercise or control group. The exercise group participates in a 9-month multimodal exercise program, starting with a 6-month period where participants exercise twice a week under the supervision of an exercise professional. After completing this 6-month period, one supervised session is replaced by one unsupervised session for 3 months. In addition, participants are instructed to be physically active for ≥30 min/day on all remaining days of the week, while being supported by an activity tracker and exercise app. Participants allocated to the control group receive standard medical care, general written physical activity advice, and an activity tracker, but no structured exercise program. The primary outcomes are quality of life (EORTC QLQ-C30, summary score) and fatigue (EORTC QLQ-FA12), assessed at baseline, 3, 6 (primary endpoint), and 9 months post-baseline. Secondary outcomes include physical fitness, physical performance, physical activity, anxiety, depression, pain, sleep problems, anthropometric data, body composition, and blood markers. Exploratory outcomes include quality of working life, muscle thickness, urinary incontinence, disease progression, and survival. Additionally, the cost-effectiveness of the exercise program is assessed. Adherence and safety are monitored throughout the intervention period. Discussion This large randomized controlled trial will provide evidence regarding the (cost-) effectiveness of exercise during treatment of metastatic breast cancer. If proven (cost-)effective, exercise should be offered to patients with metastatic breast cancer as part of standard care. Trial registration ClinicalTrials.govNCT04120298.

Whole-body vibration training for inpatient children and adolescents receiving chemotherapy for first cancer diagnosis: an exploratory feasibility study.

Abstract
AbstractWhole-body vibration (WBV) is a feasible and potentially beneficial exercise strategy for managing neuromuscular impairments like decreased strength or flexibility, mobility limitations and bone health in pediatric cancer survivors. However, as starting rehabilitation as early as possible is recommended to preserve physical function, this study investigated the feasibility of WBV for patients receiving cancer treatment for first cancer diagnosis. Eleven patients (various types of cancer, ages 7–17) participated in the supervised WBV intervention concomitant to acute cancer treatment, which involved chemotherapy. Training was implemented as part of a general exercise program and offered 3 days per week during hospitalization (warm-up, four progressive training exercises comprising 60–120 s, 21–27 Hz, 2 mm peak-to-peak-displacement). Feasibility, which was defined as the absence of WBV-related serious adverse events leading to study dropout, was primarily evaluated. Training documentation was additionally analyzed. As a main result, no serious adverse events leading to study dropout were reported. However, two incidents of bleeding (adverse events) were observed in patients with bleeding tendencies and low platelets (thrombocytes < 30,000/μL). After adjusting the platelet count threshold for WBV participation to 30,000/μL, no further incidents occurred. Moreover, due to WBV-related side effects like physical exhaustion, 11% of all training sessions had to be stopped and another 11% required reductions in the vibration load. Patients participated in 48% of the planned sessions. While main reasons for non-attendance were medical issues (35%), only few WBV sessions were missed, not completed or needed modifications due to motivational issues. Consequently, WBV seems to be feasible for inpatient pediatric patients receiving chemotherapy for first cancer diagnosis, given a sufficiently high platelet count of at least 30,000/μL. Although WBV tolerance and training motivation appear high, patient’s reduced medical condition during hospitalization can negatively impact training progression and attendance. Future research is required to confirm our findings on feasibility and to assess efficiency of WBV training for pediatric cancer patients receiving cancer treatment.

Abstract
OBJECTIVE It has been reported that local vibration therapy can benefit recovery after peripheral nerve injury, but the optimized parameters and effective mechanism were unclear. In the present study, we investigated the effect of local vibration therapy of different amplitudes on the recovery of nerve function in rats with sciatic nerve injury (SNI). METHODS Adult male Sprague-Dawley rats were subjected to SNI and then randomly divided into 5 groups: sham group, SNI group, SNI + A-1 mm group, SNI + A-2 mm group, and SNI + A-4 mm group (A refers to the amplitude; n = 10 per group). Starting on the 7th day after model initiation, local vibration therapy was given for 21 consecutive days with a frequency of 10 Hz and an amplitude of 1, 2 or 4 mm for 5 min. The sciatic function index (SFI) was assessed before surgery and on the 7th, 14th, 21st and 28th days after surgery. Tissues were harvested on the 28th day after surgery for morphological, immunofluorescence and Western blot analysis. RESULTS Compared with the SNI group, on the 28th day after surgery, the SFIs of the treatment groups were increased; the difference in the SNI + A-2 mm group was the most obvious (95% confidence interval [CI]: [5.86, 27.09], P < 0.001), and the cross-sectional areas of myocytes in all of the treatment groups were improved. The G-ratios in the SNI + A-1 mm group and SNI + A-2 mm group were reduced significantly (95% CI: [-0.12, -0.02], P = 0.007; 95% CI: [-0.15, -0.06], P < 0.001). In addition, the expressions of S100 and nerve growth factor proteins in the treatment groups were increased; the phosphorylation expressions of ERK1/2 protein in the SNI + A-2 mm group and SNI + A-4 mm group were upregulated (95% CI: [0.03, 0.96], P = 0.038; 95% CI: [0.01, 0.94], P = 0.047, respectively), and the phosphorylation expression of Akt in the SNI + A-1 mm group was upregulated (95% CI: [0.11, 2.07], P = 0.031). CONCLUSION Local vibration therapy, especially with medium amplitude, was able to promote the recovery of nerve function in rats with SNI; this result was linked to the proliferation of Schwann cells and the activation of the ERK1/2 and Akt signaling pathways.

Abstract
The diagnosis and treatment of cancer are associated with impairment at the physical and at psychological level. In addition, side effects are a potentially treatment-limiting factor that may necessitate dose reduction, delay, or even discontinuation of therapy, with negative consequences for outcome and mean survival. Numerous studies have shown that physical activity and sports and exercise therapy programs are not only practicable but also recommendable for oncologic patients during the acute phase and in the aftercare. Furthermore, nutrition plays an important role in all stages of tumor therapy. A timely integration of a nutrition therapy and physical activity in the form of physiotherapy and sports therapy serves to prevent and reduce treatment-associated side effects. Evidence-based recommendations on cancer prevention through nutrition therapy, physical activity, and sports and exercise therapy should be integrated into treatment plans for oncology patients as well as in health care services for the general population. Individual counselling by trained nutrition and exercise specialists may be advisable to receive concrete recommendations on the respective tumor entity or specific side effects. This mini review is based on a selective literature search in the PubMed database and Cochrane Central Register of Controlled Trials on the subjects of healthy diet and physical activity in primary prevention and follow-up about cancer.

Rehabilitation, exercise, and related non-pharmacological interventions for chemotherapy-induced peripheral neurotoxicity: Systematic review and evidence-based recommendations. Crit Rev Oncol Hematol 2022; 171:103575. [PMID: 34968623 PMCID: PMC10658987 DOI: 10.1016/j.critrevonc.2021.103575] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2021] [Revised: 12/23/2021] [Accepted: 12/24/2021] [Indexed: 12/22/2022] Open
Abstract
Pharmacological strategies for chemotherapy-induced peripheral neurotoxicity (CIPN) are very limited. We systematically reviewed data on rehabilitation, exercise, physical therapy, and other physical non-pharmacological interventions and offered evidence-based recommendations for the prevention and treatment of CIPN. A literature search using PubMed, Web of Science and CINAHL was conducted from database inception until May 31st, 2021. 2791 records were title-abstract screened, 71 papers were full-text screened, 41 studies were included, 21 on prevention and 20 on treatment of CIPN. Treatment type, cancer type, chemotherapy compounds were heterogeneous, sample size was small (median: N = 34) and intention-to-treat analysis was lacking in 26/41 reports. Because of the methodological issues of included studies, the reviewed evidence should be considered as preliminary. Exercise, endurance, strength, balance, and sensorimotor training have been studied in low-to-moderate quality studies, while the evidence for other treatments is preliminary/inconclusive. We offer recommendation for the design of future trials on CIPN.

Abstract
Background: Chemotherapy-induced peripheral neuropathy (CIPN) is a common and debilitating side effect of cancer treatment with no effective preventative strategy or definitive treatment. Purpose: To synthesize empiric literature from randomized controlled trials (RCTs) of pharmacological and nonpharmacological management of CIPN. Data Sources: Articles published between January 1, 2010, and February 28, 2021, were identified using keywords searching Medline, PubMed, CINAHL, Web of Science, Cochrane Library, and Embase. Study Selection: RCTs that recruited individuals who were post-chemotherapy and experienced persistent CIPN symptoms. Data Extraction and Synthesis: Three independent reviewers screened a total of 2023 abstracts. After screening, full-text review, and quality appraisal, 22 articles were included in this review. Data related to study design, participant characteristics, interventions, controls, outcome measures, and relevant findings were extracted from full texts. Descriptive quantitative summaries were calculated and narrative analysis was performed. Results: Of the 22 studies, 4 investigated pharmacologic treatments, 2 compared acupuncture to pharmacologic treatments, and 16 studies examined nonpharmacologic treatments. Pharmacologic studies reported mixed results with evidence of participant response varying by history of chemotherapeutic agent. Acupuncture, exercise/physical therapy, and neurofeedback appear to be effective treatments for CIPN. Evidence regarding biophysical agents and cognitive-behavioral therapy is equivocal. Scrambler therapy is not supported. Limitations: Studies included in this review share several limitations, including widely variable outcome measures, small and demographically homogenous samples, and nonstandardized treatment protocols. Conclusion: This scoping review summarized the current body of high-quality RCTs investigating treatment for CIPN. The majority of studies in this review reports benefits of pharmacologic and nonpharmacologic interventions, although management may require a multipronged approach and should be tailored to the individual. Clinical implications are proposed and suggestions made for future research include implementation of standardized intervention protocols, use of outcome measures representative of the spectrum of CIPN symptoms, and stratification by the chemotherapeutic agent.

Abstract
INTRODUCTION Chemotherapy-induced peripheral neurotoxicity (CIPN) remains a significant toxicity in cancer survivors without preventative strategies or rehabilitation. Exercise and physical activity-based interventions have demonstrated promise in reducing existing CIPN symptoms and potentially preventing toxicity, however there is a significant gap in evidence due to the lack of quality clinical trials and appropriate outcome measures. AREAS COVERED We systematically reviewed outcome measures in CIPN exercise and physical rehabilitation studies with expert panel consensus via the Peripheral Nerve Society Toxic Neuropathy Consortium to provide recommendations for future trials. Across 26 studies, 75 outcome measures were identified and grouped into 16 domains within three core areas - measures of manifestations of CIPN (e.g. symptoms/signs), measures of the impact of CIPN and other outcome measures. EXPERT OPINION This article provides a conceptual framework for CIPN outcome measures and highlights the need for definition of a core outcome measures set. The authors provide recommendations for CIPN exercise and physical rehabilitation trial design and outcome measure selection. The development of a core outcome measure set will be critical in the search for neuroprotective and treatment approaches to support cancer survivors and to address the gap in the identification of effective rehabilitation and treatment options for CIPN.

Abstract
OPINION STATEMENT Chemotherapy-induced peripheral neuropathy (CIPN) is a common toxicity associated with treatment with platinum-based agents, taxanes, vinca alkaloids, and other specific agents. The long-term consequences of this condition can result in decreased patient quality of life and can lead to reduced dose intensity, which can negatively impact disease outcomes. There are currently no evidence-based preventative strategies for CIPN and only limited options for treatment. However, there are several strategies that can be utilized to improve patient experience and outcomes as more data are gathered in the prevention and treatment setting. Before treatment, patient education on the potential side effects of chemotherapy is key, and although trials have been limited, recommending exercise and a healthy lifestyle before and while undergoing chemotherapy may provide some overall benefit. In patients who develop painful CIPN, our approach is to offer duloxetine and titrate up to 60 mg daily. Chemotherapy doses may also need to be reduced if intolerable symptoms develop during treatment. Some patients may also try acupuncture and physical therapy to help address their symptoms, although this can be limited by cost, time commitment, and patient motivation. Additionally, data on these modalities are currently limited, as studies are ongoing. Overall, approaching each patient on an individual level and tailoring treatment options for them based on overall physical condition, their disease burden, goals of care and co-morbid health conditions, and willingness to trial different approaches is necessary when addressing CIPN.

Abstract
INTRODUCTION Peripheral neuropathies are a prevalent, heterogeneous group of diseases of the peripheral nervous system. Symptoms are often debilitating, difficult to treat, and usually become chronic. Not only do they diminish patients' quality of life, but they can also affect medical therapy and lead to complications. To date, for most conditions there are no evidence-based causal treatment options available. Research has increased considerably since the last review in 2014 regarding the therapeutic potential of exercise interventions for patients with polyneuropathy. OBJECTIVE Our objective in this systematic review with meta-analysis was to analyze exercise interventions for neuropathic patients in order to update a systematic review from 2014 and to evaluate the potential benefits of exercise on neuropathies of different origin that can then be translated into practice. METHODS Two independent reviewers performed a systematic review with meta-analysis according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Inclusion criteria according to the PICOS approach were: neuropathic patients, exercise interventions only, an inactive or non-exercising control group, and solely randomized controlled trials with the following outcome parameters: neuropathic symptoms, balance parameters, functional mobility, gait, health-related quality of life, and HbA1c (glycated hemoglobin). RESULTS A total of 41 randomized, controlled trials met all inclusion criteria, 20 of which could be included in the quantitative analysis. Study quality varied from moderate to high. Current data further support the hypothesis that exercise is beneficial for neuropathic patients. This is best documented for patients with diabetic peripheral neuropathy (DPN) (27 studies) as well as for chemotherapy-induced peripheral neuropathy (CIPN) (nine studies), while there are only few studies (five) on all other causes of neuropathy. We found standardized mean differences in favor of the exercise group of 0.27-2.00 for static balance, Berg Balance Scale, Timed-up-and-go-test, nerve conduction velocity of peroneal and sural nerve as well as for HbA1c in patients with DPN, and standardized mean differences of 0.43-0.75 for static balance, quality of life, and neuropathy-induced symptoms in patients with CIPN. CONCLUSION For DPN, evidence-based recommendations can now be made, suggesting a combination of endurance and sensorimotor training to be most beneficial. For patients with CIPN, sensorimotor training remains the most crucial component. For all other neuropathies, more high-quality research is needed to derive evidence-based recommendations. Overall, it seems that sensorimotor training has great potential to target most neuropathies and combined with endurance training is therefore currently the best treatment option for neuropathies.

Abstract
Peripheral nerve injury is a complex condition with a variety of signs and symptoms depending on the severity and nerves involved. Peripheral nerve damage may lead to sensory and motor functions deficits and even lifelong disability, causing important socioeconomic costs worldwide. Despite the increase in knowledge of the mechanisms of injury and regeneration, a full functional recovery is still unsatisfying in the majority of patients. It is well known that exercise promotes physical and psychological well-being, by ameliorating general health. In the last years, there has been a growing interest in evaluating the effects of exercise on the peripheral nervous system. Experimental works with rodent models showed the potential utility of exercise following peripheral nerve injuries, as evinced by increasing axon regeneration, muscle reinnervation, better recovery of strength, muscle mass and higher expression of neurotrophic factors. Moreover, clinical evidence showed positive trends in favour of physical therapy following peripheral nerve damage based on the improvement of range of motion (ROM), muscle power grade and pain. After a brief overview of peripheral nerve anatomy and the different types of nerve injury, the present review aims to summarize the impact of exercise on peripheral nerve regeneration. Some clinical evidence regarding the effect of exercise after peripheral nerve injury will also be discussed.

Abstract
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.

Abstract
BACKGROUND Chemotherapy-induced peripheral neuropathy (CIPN) is a common, unpleasant and usually long-lasting side effect of neurotoxic chemotherapeutic agents. This study aimed to investigate the preventive potential of sensorimotor- (SMT) and resistance training (RT) on CIPN. METHODS Patients (N = 170) were randomised to SMT, RT or usual care (UC). Both exercise groups trained 3×/week for a total of 105 min/week during neurotoxic chemotherapy (mean length: 20 weeks). Before and 3 weeks after neurotoxic chemotherapy, CIPN signs/symptoms were assessed via Total Neuropathy Score (TNSr; primary endpoint) and EORTC QLQ-CIPN15 questionnaire. In addition, balance (centre of pressure), muscle strength (isokinetic), quality of life (QoL, EORTC QLQ-C30) and relative chemotherapy dose intensity (RDI) were investigated. The follow-up period covered 6 months after the end of chemotherapy. RESULTS Intention-to-treat analyses (N = 159) revealed no differences regarding CIPN signs/symptoms. Exploratory per-protocol analyses (minimum training attendance rate 67%; N = 89) indicated that subjectively perceived sensory symptoms in the feet increased less during chemotherapy in the adherent exercisers (pooled group: SMT+RT) than in the UC group (-8.3 points (-16.1 to -0.4); P = 0.039, ES = 1.27). Furthermore, adherent exercisers received a higher RDI (96.6 ± 4.8 vs. 92.2 ± 9.4; P = 0.045), showed a better course of muscular strength (+20.8 Nm (11.2-30.4); P < 0.001, ES = 0.57) and QoL (+12.9 points (3.9-21.8); P = 0.005, ES = 0.64). During follow-up, CIPN signs/symptoms persisted in all groups. CONCLUSIONS This study demonstrates that SMT and/or RT alleviate subjectively perceived sensory CIPN symptoms in the feet and other clinically relevant cancer therapy-related outcomes, if an appropriate training stimulus is achieved.

Abstract
INTRODUCTION/AIMS Clinically, the chemotherapeutic agent oxaliplatin can cause peripheral neuropathy, impaired balance, and muscle wastage. Using a preclinical model, we investigated whether exercise intervention could improve these adverse conditions. METHODS Mice were chronically treated with oxaliplatin alone or in conjunction with exercise. Behavioral studies, including mechanical allodynia, rotarod, open-field, and grip-strength tests, were performed. After euthanasia, multiple organs and four different muscle types were dissected and weighed. The cross-sectional area (CSA) of muscle fibers in the gastrocnemius muscle was assessed and gene expression analysis performed on the forelimb triceps muscle. RESULTS Oxaliplatin-treated mice displayed reduced weight gain, mechanical allodynia, and exploratory behavior deficits that were not significantly improved by exercise. Oxaliplatin-treated exercised mice showed modest evidence of reduced muscle wastage compared with mice treated with oxaliplatin alone, and exercised mice demonstrated evidence of a mild increase in CSA of muscle fibers. DISCUSSION Exercise intervention did not improve signs of peripheral neuropathy but moderately reduced the negative impact of oxaliplatin chemotherapy related to muscle morphology, suggesting the potential for exploring the impact of exercise on reducing oxaliplatin-induced neuromuscular toxicity in cancer patients.

Type of exercise may influence postural adaptations in chemotherapy-induced peripheral neuropathy. Ann Clin Transl Neurol 2021; 8:1680-1694.

Abstract
OBJECTIVE Traditional posturography measurements characterize postural instability in patients with chemotherapy-induced peripheral neuropathy (CIPN), while underlying postural control mechanisms remain unclear. Taking a model-based approach can yield insights into these mechanisms. This study's aim was to characterize the modifications in postural control of CIPN patients associated with exercise in relation to the postural behavior of healthy control participants (hCON) via an exploratory approach. METHODS Thirty-one CIPN patients were randomly assigned to two interventions (balance plus moderate endurance training vs. moderate endurance training only) and exercised twice per week over 12 weeks. Baseline data were compared to 36 matched hCONs. We recorded spontaneous sway and postural reactions to platform tilts using Optotrak and a Kistler force platform pre- and post-intervention. Data interpretation relied on a model-based parameter identification procedure. RESULTS Spontaneous sway amplitudes were larger and postural reactions smaller, with a relative phase advance, in our pre-intervention patients than the hCONs. Post-intervention, spontaneous sway, and postural reactions were reduced and the sensory-motor ratio larger in both groups, while the postural reaction timing differed between groups. INTERPRETATION The abnormally small postural reactions in CIPN patients before the intervention can be interpreted as the consequence of abnormally strong velocity control-a strategy modification that may serve as a prediction mechanism to compensate for the lack of timely and accurate proprioceptive signals. While both groups reduced postural sway and showed an adapted sensory-motor ratio post-intervention, the interventions seemed to trigger different velocity control strategies. This study emphasizes the need for taking a more differentiated perspective on intervention effects.

Abstract
Abstract
Purpose
Reduced physical performance due to therapy-related dysfunctions in children diagnosed with cancer contributes to insufficient physical activity levels. It is therefore essential that relevant functions are restored. Whole-body vibration (WBV) training, a neuromuscular stimulating exercise intervention, could have the potential to target those functions adequately. Therefore, the aim of this study was to evaluate the feasibility of a combined supervised and home-based WBV intervention with children after inpatient oncological treatment.
Methods
Eight children aged 6–21 years were included after cessation of their inpatient oncological treatment. They performed a 12-week WBV training including one supervised and two home-based sessions per week according to a standardized training protocol. Feasibility, adherence and compliance to the vibration protocol were documented. Subjective benefits and satisfaction were assessed using a questionnaire.
Results
Study participants attended 84.03 ± 13.09% of WBV sessions. No serious adverse events occurred. Some patients reported side effects partially resulting in modifications of the vibration protocol by therapists. Almost all children regarded the intervention as beneficial.
Conclusion
A combined supervised and home-based WBV intervention with children after inpatient oncological treatment is feasible and safe. The beneficial potential regarding relevant sensory and motor dysfunctions is now to be investigated.

Abstract
BACKGROUND Peripheral neurotoxicity is common in patients with digestive malignancies receiving chemotherapy containing oxaliplatin, and there is still no effective drug to prevent or treat this complication. METHODS Seventy-nine patients receiving chemotherapy containing oxaliplatin were included, and the relationship between chemotherapy regimens, cycles, and cumulative dose of oxaliplatin and peripheral neurotoxicity was analyzed. Patients were divided into two groups of control or intervention. Twenty-eight patients in the control group received routine chemotherapy care, and 51 patients in the intervention group underwent two-week exercise rehabilitation program. Patients' Functional Assessment of Cancer Therapy/Gynecologic Oncology Group - Neurotoxicity (FACT/GOG-Ntx), functional tests, and Brief Pain Inventory(BPI) scores as well as interference life scores were assessed before intervention and two weeks after the intervention. RESULTS In the intervention group, 52.9% patients previously exercised regularly. The FOLFOX regimen was more common in peripheral neurotoxicity (73.4%), and the median oxaliplatin cycles for neurotoxicity was 9 (ranging from 1 to 16). The mean cumulative dose of oxaliplatin was 1080.02 ± 185.22 mg, both the cycles and cumulative dose were positively correlated with the occurrence of peripheral neurotoxicity. Compared with control, the scores of FACT/GOG-Ntx, functional tests, and BPI were significantly decreased in the intervention group (p < 0.05). CONCLUSION Chemotherapy cycles and cumulative doses were in relation with OIN , and exercise rehabilitation program could effectively alleviate OIN.<br />.

Abstract
An analytical review of the methods of cancer patients' rehabilitation with peripheral polyneuropathy induced by cytostatics (PNPIC) was carried out. Studies from electronic databases were investigated: Scopus, Web of Science, MedLine, World Health Organization, The Cochrane Central Register of Controlled Trials, ScienceDirect, US National Library of Medicine National Institutes of Health, PubMed Cancer, eLIBRARY, CyberLeninka. Despite the improvement of anticancer therapy and an increase in patients' life expectancy, the emerging peripheral polyneuropathy remains an urgent problem, since it significantly affects both the patients' life quality and the selection of adequate therapy. The frequency of detection of PNPIC is 90%, after discontinuation of treatment; symptoms of damaged peripheral nerve fibers remain in 30% of patients. The clinical symptoms of PNPIC are varied and most often include numbness in the extremities and / or increased sensitivity to thermal or mechanical stimuli, neuropathic pain. Currently, to prevent PNPIC, treatment is being modified with a reduction in the duration of courses and doses of cytostatics, and interruption of treatment. Official guidelines do not recommend any prophylaxis other than the possible use of duloxetine or a topical gel containing baclofen, amitriptyline, and ketamine. Over the past few years, there has been no significant progress in the prevention and treatment of PNPIC. The most common drug treatment method in clinical practice is the prescription of vitamins B. Among the non-drug treatment methods of PNPIC, the authors used acupuncture, electro-acupuncture, manual therapy, massage, gymnastics, yoga, sensorimotor training, general vibration therapy, percutaneous electro-neuro-stimulation, electro-analgesia, local cryotherapy, hydrotherapy, low-intensity alternating magnetic radiation. The studies included in the review are heterogeneous in design and protocol, number of patients, and time points for assessing outcomes. In connection with the existing differences, it is not possible to carry out a comparative analysis of the results of these rehabilitation types and to give an unambiguous answer about their effectiveness. As the analysis has shown, peripheral PNPIC is well known all over the world, however, the search for methods of its treatment is far from complete.

Abstract
Chemotherapy-induced peripheral neuropathy (CIPN) is an unsolved and potentially life-compromising problem for most patients receiving neurotoxic chemotherapy. It manifests with numbness, tingling, and possibly neuropathic pain and motor and autonomic symptoms. This review aims to provide an evidence synthesis that prepares nurses to comprehensively assess, provide supportive care for, and critically evaluate the literature on CIPN. The prevalence, significance, characteristics, mechanisms, and risk factors of CIPN will be discussed, as well as nursing-relevant evidence on the assessment, prevention, and management of CIPN. The importance of critical literature evaluation before clinical implementation to reduce physical and financial harms to patients will also be highlighted.

Chemotherapy-induced peripheral neuropathy: longitudinal analysis of predictors for postural control. Sci Rep 2021; 11:2398. [PMID: 33504885 PMCID: PMC7840973 DOI: 10.1038/s41598-021-81902-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2020] [Accepted: 01/12/2021] [Indexed: 11/09/2022] Open
Abstract
Impaired postural control is often observed in response to neurotoxic chemotherapy. However, potential explanatory factors other than chemotherapy-induced peripheral neuropathy (CIPN) have not been adequately considered to date due to primarily cross-sectional study designs. Our objective was to comprehensively analyze postural control during and after neurotoxic chemotherapy, and to identify potential CIPN-independent predictors for its impairment. Postural control and CIPN symptoms (EORTC QLQ-CIPN20) were longitudinally assessed before, during and three weeks after neurotoxic chemotherapy, and in three and six months follow-up examinations (N = 54). The influence of peripheral nerve function as determined by nerve conduction studies (NCS: compound motor action potentials (CMAP) and sensory action potentials (SNAP)), physical activity, and muscle strength on the change in postural control during and after chemotherapy was analyzed by multiple linear regression adjusted for age and body mass index. Postural control, CIPN signs/symptoms, and CMAP/SNAP amplitudes significantly deteriorated during chemotherapy (p < .01). During follow-up, patients recovered from postural instabilities (p < .01), whereas CIPN signs/symptoms and pathologic NCS findings persisted compared to baseline (p < .001). The regression model showed that low CMAP and high SNAP amplitudes at baseline predicted impairment of postural control during but not after chemotherapy. Hence, pre-therapeutically disturbed somatosensory inputs may induce adaptive processes that have compensatory effects and allow recovery of postural control while CIPN signs/symptoms and pathologic peripheral nerve function persist. Baseline NCS findings in cancer patients who receive neurotoxic chemotherapy thus might assist in delineating individual CIPN risk profiles more precisely to which specific exercise intervention programs could be tailor-made.

Abstract
PurposeHematopoietic stem cell transplant (HSCT) patients can suffer from long-term transplant-related complications that affect their quality of life and daily activities. This study, a narrative review, aims to report the impact of HCT complications, the benefits of rehabilitation intervention, the need for long-term care and highlights the research gap in clinical trials involving rehabilitation.Design/methodology/approachA comprehensive search strategy was performed on several databases to look for relevant articles published from 1998 to 2018. Articles published in English with the following terms were used: hematopoietic stem cell transplant, chronic graft-versus-host disease, rehabilitation, exercise, physical therapy, occupational therapy. A patient/population, intervention, comparison, and outcomes (PICO) framework was employed to ensure that the search strategies were structured and precise. Study year, design, outcome, intervention, sample demographics, setting and study results were extracted.FindingsOf the 1,411 records identified, 51 studies underwent title/abstract screening for appropriateness, 30 were reviewed in full, and 19 studies were included in the review. The review found that, for the majority of patients who underwent HSCT and developed treatment-related complications, rehabilitation exercises had a positive impact on their overall quality of life. However, exercise prescription in this patient group has not always reflected the scientific approach; there is a lack of high-quality clinical trials in general. The review also highlights the need to educate healthcare policymakers and insurance companies responsible for rationing services to recognise the importance of offering long-term follow-up care for this patient group, including rehabilitation services.Practical implicationsA large number of HSCT patients require long-term follow-up from a multidisciplinary team, including rehabilitation specialists. It is important for healthcare policymakers and insurance companies to recognise this need and take the necessary steps to ensure that HSCT patients receive adequate long-term care. This paper also highlights the urgent need for high-quality rehabilitation trials to demonstrate the feasibility and importance of rehabilitation teams.Originality/valueHealthcare policymakers and insurance companies need to recognise that transplant patients need ongoing physiotherapy for early identification of any functional impairments and appropriate timely intervention.

Abstract
PURPOSE Chemotherapy-induced peripheral neuropathy (CIPN) is challenging for oncologists. Many publications mention the high incidence of CIPN and the lack of effective preventive/management strategies and robust diagnostic tools. This cross-sectional study was aimed at assessing the practice of French oncologists for CIPN prevention, diagnosis and management. METHODS This web-based survey was sent to French oncologists by the regional cancer networks. Incidence and impact of CIPN were assessed using visual analogue scales (VAS) and diagnostic strategies were recorded. Also recorded were the drugs used to prevent or manage CIPN and their perceived efficacy and safety (VAS). RESULTS Among the 210 oncologists included, the perceived incidence of CIPN was about 36.2 ± 22.1% of patients. About 99.5% of oncologists declared that they assess CIPN during medical follow-up. The use of drugs to prevent CIPN was reported by 9.6% of oncologists (group B vitamins (35.0%) and calcium and magnesium infusion (25.0%)). In the case of CIPN, the therapeutic adjustment of neurotoxic anticancer drugs is performed by 99.0% of oncologists (chemotherapy change (49.8%), dose reduction (30.9%) or interruption (19.3%)). The pharmacological management of CIPN was declared by 72.9% of oncologists. The main drugs used are pregabalin (75.8%), amitriptyline (32.7%) and gabapentin (25.5%). Duloxetine (ASCO recommendation) is used by only 11.8% of oncologists. CONCLUSION Oncologists were clearly aware of CIPN risks, but its incidence tended to be underestimated and the ASCO recommendations for the management of CIPN were not followed. The prevention, diagnosis and management of CIPN remain problematic in clinical practice in France. TRIAL REGISTRATION ClinicalTrials.gov : NCT03854864.

Impact of whole-body vibration exercise on physical performance and bone turnover in patients with monoclonal gammopathy of undetermined significance. J Bone Oncol 2020; 25:100323. [PMID: 33083217 PMCID: PMC7551327 DOI: 10.1016/j.jbo.2020.100323] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2020] [Revised: 09/17/2020] [Accepted: 09/21/2020] [Indexed: 12/18/2022] Open
Abstract
OBJECTIVE Monoclonal Gammopathy of Undetermined Significance (MGUS) is a risk factor for reduced physical performance, osteoporosis, and fractures due to compromised musculoskeletal metabolism. In this condition it is unknown whether whole-body vibration (WBV) exercise favorably alters physical performance and bone metabolism. METHODS To evaluate the effect of three-months WBV exercise (30 min; 2x/week) including an optional three-month extension on physical performance, bone metabolism and bone mineral density. Endpoints included functional assessments, bone turnover markers and bone mineral density assessed by peripheral quantitative computed tomography of the tibia. RESULTS Fifteen MGUS patients (median age 62.0, nine female) completed the first three months of which ten completed the three-month extension. Measures of physical functioning including chair rise test, timed up and go and 6-minute walk test improved (p = 0.007; p = 0.009; p = 0.005) after three and six months of WBV exercise. Total tibial bone mineral density remained unaltered (p > 0.05). WBV exercise tended to increase levels of sclerostin (p = 0.093) with a transient increase in osteoclast resorption markers (N-terminal telopeptide of collagen type 1, tartrate resistant acid phosphatase 5b) after three months while Dickkopf-1 (p = 0.093), procollagen I N-terminal propeptide (p = 0.074) and total alkaline phosphatase (p = 0.016) appeared to decline. No exercise-related adverse events were reported. CONCLUSION WBV exercise in MGUS patients improves indicators of physical performance. Observed trends in bone turnover markers and changes in distal tibial bone mineral density may indicate a regulatory effect of WBV exercise on bone metabolism and warrants further evaluation by large scale studies.

Abstract
OBJECTIVES To evaluate for differences in demographic and clinical characteristics, as well as subjective and objective measures of chemotherapy-induced peripheral neuropathy (CIPN), among different exercise groups. SAMPLE & SETTING Cancer survivors (N = 290) were recruited from throughout the San Francisco Bay Area. METHODS & VARIABLES Based on the recommended 150 minutes or more of exercise per week, survivors were classified into the no exercise (NoEx), less exercise (LessEx), or recommended exercise (RecEx) group. Survivors completed self-report questionnaires and underwent sensory and balance testing. RESULTS Compared to the RecEx group, survivors in the NoEx group had less education, were less likely to be married/partnered, had a lower household income, had a higher level of comorbidity, and had poorer functional status. No differences were found among the groups in CIPN duration; pain intensity scores; or changes in light touch, cold, and pain sensations. IMPLICATIONS FOR NURSING Clinicians can recommend walking as a therapeutic option for survivors with CIPN and refer them to physical therapy.

Abstract
Sensor technologies for health care, research, and consumers have expanded and evolved rapidly. Many technologies developed in commercial or engineering spaces, lack theoretical grounding and scientific evidence to support their need, safety, and efficacy. Theory is a mechanism for synthesizing and guiding knowledge generation for the discipline of nursing, including the design, implementation, and evaluation of sensors and related technologies such as artificial intelligence and machine learning. In this paper, three nurse scientists summarize their presentations at the Council for the Advancement of Nursing Science 2019 Advanced Methods Conference on Expanding Science of Sensor Technology in Research discussing the theoretical underpinnings of sensor technologies development and use in nursing research and practice. Multiple theories with diverse epistemological roots guide decision-making about whether or not to apply sensors to a given use; development of, components of, and mechanisms by which sensor technologies are expected to work; and possible outcomes.

Abstract
Background Despite the increasing knowledge of the etiology of neuropathic pain, this type of chronic pain is resistant to available analgesics in approximately 50% of patients and therefore is continuously a subject of considerable interest for physiologists, neurologists, medicinal chemists, pharmacologists and others searching for more effective treatment options for this debilitating condition. Materials and methods The present review article is the first of the two articles focused on chemotherapy-induced peripheral neuropathy (CIPN). Results CIPN is regarded as one of the most common drug-induced neuropathies and is highly pharmacoresistant. The lack of efficacious pharmacological methods for treating CIPN and preventing its development makes CIPN-related neuropathic pain a serious therapeutic gap in current medicine and pharmacotherapy. In this paper, the most recent advances in the field of studies on CIPN caused by platinum compounds (namely oxaliplatin and cisplatin), taxanes, vinca alkaloids and bortezomib are summarized. Conclusions The prevalence of CIPN, potential causes, risk factors, symptoms and molecular mechanisms underlying this pharmacoresistant condition are discussed. Graphic abstract ![]()

Out of balance - Postural control in cancer patients before and after neurotoxic chemotherapy. Gait Posture 2020; 77:156-163.

Abstract
BACKGROUND Chemotherapy-induced peripheral neuropathy (CIPN) is a serious side effect deriving from neurotoxic chemotherapeutic agents. The underlying nerve injury can affect proprioception causing impaired postural control, gait difficulties and a higher risk of falling. Overall, the symptoms and functional limitations negatively affect patients' independence and quality of life. RESEARCH QUESTION Our objective was to analyze postural control in cancer patients before and after neurotoxic chemotherapy and to compare these data to healthy controls. METHODS Participants were 35 cancer patients (PAT) and 35 healthy, one-to-one gender, age, height, and weight matched controls (HMC). Postural control of HMC was tested once, whereas PAT were tested prior to (PATpre) and three weeks after completion of neurotoxic chemotherapy (PATpost). Temporal, spatial and frequency domain measures of the center of pressure (COP) were calculated using a force plate. The following balance conditions were analyzed: bipedal stance with open (BPEO) and closed eyes (BPEC), semi-tandem (STEO, STEC) and monopedal stance (MPEO). CIPN was assessed clinically (Total Neuropathy Score) and via questionnaire. Time and group differences were determined by using Wilcoxon-signed-rank tests. Spearman correlation was applied to analyze associations between severity of CIPN and postural control. RESULTS PATpost showed significantly increased temporal and spatial measures of the COP (p < .05) - both after neurotoxic chemotherapy (PATpre-PATpost) and in comparison to HMC. Withdrawal of visual control resulted in greater temporal and spatial COP displacements in PATpost than in the comparative groups (PATpre, HMC). Correlation analyzes revealed moderate associations of COP measures with clinical CIPN measures and low to none for the questionnaires. SIGNIFICANCE Three weeks after completion of neurotoxic chemotherapy, PATpost showed significant balance deficits compared to PATpre and HMC. Especially the deficits in the standing conditions with closed eyes may indicate an impaired proprioception. This hypothesis is supported by the finding that stronger CIPN symptoms were associated with poorer postural control. However, future studies need to take further influencing factors on postural control into account (e.g. strength) in order to generate efficacious rehabilitation measures.

Abstract
CONTEXT Recent, albeit, limited evidence suggests that body mass index (BMI) may be a modifiable risk factor to reduce the deleterious effects of chemotherapy-induced peripheral neuropathy (CIPN) in cancer survivors. OBJECTIVES To evaluate for differences in demographic, clinical, pain, sensation, and balance characteristics among three BMI groups. We hypothesized that as BMI increased, survivors would report higher pain intensity scores and have significant decrements in measures of sensation and balance. METHODS A total of 416 survivors with CIPN were evaluated using subjective and objective measures of CIPN. Survivors were divided into three BMI groups (i.e., normal weight, overweight, and obese). Differences among the BMI groups were evaluated using parametric and nonparametric statistics. RESULTS Of the 416 survivors, 45.4% were normal weight, 32.5% were overweight, and 22.1% were obese. Compared with the normal-weight group, survivors in the other two groups had lower functional status scores, a higher comorbidity burden, higher pain intensity scores, and higher interference scores. In addition, compared with the normal-weight group, survivors in the other two BMI groups had significantly worse balance scores. CONCLUSION Our findings support the hypothesis that as BMI increased, pain sensation and balance characteristics worsened. Our findings suggest that nutritional counseling as well as exercise and weight management programs in survivors with CIPN may improve these clinically important problems.

Abstract
Background Chemotherapy-induced peripheral neuropathy (CIPN) remains as a big unsolved challenge for cancer patients and oncologists. However, there is no effective treatment to prevent and cure it. This systematic review and meta-analysis chiefly aimed to assess the effectiveness and safety on the method of activating blood and dredging collaterals in traditional Chinese medicine (TCM) for reducing CIPN. Methods Two authors comprehensively searched all the randomized controlled trials (RCTs) via PubMed, Cochrane, China National Knowledge Infrastructure (CNKI), and Wanfang Database of China Science Periodical Database (CSPD). The Review Manager (RevMan) 5.0 was used to conduct the meta-analysis. Results 20 trials including 1481 participants were analyzed. 15 trials tested the incidence of all-grade CIPN which was significantly lower in intervention arm and 16 trails presented that the result of high-grade CIPN was the same. The total effective rate of the use of Chinese herbs was 77.19% versus 45.79% in the comparator group. Besides, the use of Chinese herbs statistically promoted the sensory nerve conduction velocity (SNCV) and the motor nerve conduction velocity (MNCV). Besides, the quality of life (QoL) in the intervention group was better than the comparator one. Herbs-related adverse events were skin allergy, skin chap, and scald, which could be managed well. Conclusions The work involving studies of the effectiveness and safety on TCM for reducing CIPN proves to be encouraging. Herbs with the function of activating blood and dredging collaterals were found to potentially promote the curative effects as well as making improvements of SNCV and MNCV. However, in the future, more double-blind, multicenter, large-scale RCTs and more comprehensive researches are still required.

Abstract
BACKGROUND Chemotherapy-induced peripheral neuropathy (CIPN) is a dose-limiting adverse effect of taxanes. We sought to evaluate the effect of exercise on taxane CIPN in women with breast cancer. PATIENTS AND METHODS Women (n = 27) were randomized to immediate exercise (IE, during taxane chemotherapy) or delayed exercise (DE, after chemotherapy). Supervised aerobic, resistance, and balance training was offered 3 days a week for 8-12 weeks. CIPN symptoms and quality of life were assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ) C30 and CIPN20 (scored from 0 to 100). The percentage of participants reporting moderate to severe sensory symptoms ('3/4' or '4/4' for CIPN20 sensory items) was also evaluated, along with clinical sensory testing at the lower limb (vibration sense and pinprick). Taxane treatment adherence, including relative dose intensity, was extracted from patient medical records. Assessments occurred at: baseline (before taxane chemotherapy), pre-cycle 4 (before the final taxane cycle), the end of chemotherapy, and follow-up (10-15 weeks after chemotherapy). RESULTS No differences in the EORTC QLQ CIPN20 symptom scores were detected between groups at any time point. At pre-cycle 4, there was a significant difference between groups in patient-reported moderate to severe numbness in the toes or feet (IE: n = 1, 9%, DE: n = 7, 50%, P = .04) and impaired vibration sense in the feet (IE: n = 2, 18%, DE: n = 10, 83%, P < .01). Overall global health status/quality of life was higher in IE compared to DE at the end of chemotherapy (P = .05), yet both groups had worse CIPN20 sensory (Δ24.3 ± 4.6, P < .01) and motor symptom scores (Δ10.5 ± 1.9, P < .01) relative to baseline. By the end of chemotherapy, no differences between groups were found for moderate to severe numbness in the toes or feet (P = 1.0) or impaired vibration sense in the feet (P = .71). More IE participants received ≥ 85% relative dose intensity (IE: n = 12, 100%, DE: n = 10, 67%, P < .05). CONCLUSION Exercise may attenuate CIPN over the course of taxane chemotherapy and possibly improve taxane adherence in women with breast cancer. These findings, as well as whether exercise can attenuate CIPN by the end of taxane chemotherapy, should be confirmed in larger trials.

Mobility in survivors with chemotherapy-induced peripheral neuropathy and utility of the 6-min walk test. J Cancer Surviv 2019; 13:495-502. [PMID: 31172429 DOI: 10.1007/s11764-019-00769-7] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2019] [Accepted: 05/17/2019] [Indexed: 10/26/2022]
Abstract
BACKGROUND Chemotherapy-induced peripheral neuropathy (CIPN) is a significant and often lasting side effect of cancer treatment, with increasing CIPN severity associated with increasing deficits in balance, gait, and mobility. The 6-min walk test (6MWT) is a widely validated and utilized measure of general physical functioning and mobility, although its utility in a CIPN context is unclear. This study aimed to determine the utility of the 6MWT as an assessment of mobility deficits in a CIPN cohort and utilize the 6MWT to compare mobility data from CIPN patients to those of healthy and clinical populations. METHODS Cancer survivors exposed to neurotoxic chemotherapies (N = 100; mean 17 ± 13 months post-treatment; mean age 59 ± 13 years) completed a single cross-sectional assessment of patient-reported and objective CIPN, mobility (6MWT), and disability. RESULTS CIPN symptoms were reported in the majority of the cohort (87%). Increasing age, patient-reported and objective CIPN symptoms, and disability were associated with decreasing 6MWT distance (.48 ≤ R ≤ .63; p < .001) in bivariate models. Multiple regression models of 6MWT distance included age, sex, and patient-reported or objective CIPN severity as significant independent correlates (.62 ≤ R ≤ .64; p < .03). 6MWT distances in patients with CIPN symptom severity above the cohort mean were consistent with mean values reported in diabetic neuropathy and clinical populations. CONCLUSIONS Increased CIPN symptoms are associated with increased mobility deficits. The 6MWT demonstrates promising utility as a mobility assessment in a CIPN cohort. IMPLICATIONS FOR CANCER SURVIVORS The impact of the progression of CIPN on mobility deficits in survivors emphasizes the need for effective interventions to treat and prevent CIPN.

Abstract
Background Chemotherapy-induced peripheral neuropathy (CIPN) can affect functional performance and quality of life considerably. Since balance training has proven to enhance physical function, it might be a promising strategy to manage CIPN-induced functional impairments. Methods Fifty cancer survivors with persisting CIPN after finishing their treatment were randomly allocated to an intervention (IG) or active control group (CG). The IG did endurance plus balance training, the CG only endurance training (twice weekly over 12 weeks). Pre- and post-assessments included functional performance, cardiorespiratory fitness, vibration sense, and self-reported CIPN symptoms (EORTC QLQ-CIPN20). Results Intention-to-treat analyses (n = 41) did not reveal a significant group difference (CG minus IG) for sway path in semi-tandem stance after intervention (primary endpoint), adjusted for baseline. However, our per-protocol analysis of 37 patients with training compliance ≥70% revealed: the IG reduced their sway path during semi-tandem stance (− 76 mm, 95% CI -141 – -17; CG: -6 mm, 95% CI -52 – 50), improved the duration standing on one leg on instable surface (11 s, 95% CI 8–17; CG: 0 s, 95%CI 0–5) and reported decreased motor symptoms (−8points, 95% CI -18 – 0; CG: -2points 95% CI -6 – 2). Both groups reported reduced overall- (IG: -10points, 95% CI -17 – -4; CG: -6points, 95% CI -11 – -1) and sensory symptoms (IG: -7points, 95% CI -15 – 0; CG: -7points, 95% CI -15 – 0), while only the CG exhibited objectively better vibration sense (knuckle: 0.8points, 95% CI 0.3–1.3; IG: 0.0points, 95% CI -1.1 – 0.9; patella: 1.0points, 95% CI 0.4–1.6: IG: -0.8points, 95% CI -0.2 – 0.0). Furthermore, maximum power output during cardiopulmonary exercise test increased in both groups (IG and CG: 0.1 W/kg, 95% CI 0.0–0.2), but only the CG improved their jump height (2 cm, 95% CI 0.5–3.5; IG: 1 cm, 95% CI -0.4 – 3.2). Conclusion We suppose that endurance training induced a reduction in sensory symptoms in both groups, while balance training additionally improved patients’ functional status. This additional functional effect might reflect the IG’s superiority in the CIPN20 motor score. Both exercises provide a clear and relevant benefit for patients with CIPN.

Abstract
INTRODUCTION Chemotherapy-induced peripheral neuropathy (CIPN) is a prevalent and clinically meaningful side effect of cancer treatment. CIPN is induced by neurotoxic agents, causing severe sensory and/or motor deficits, resulting in disability and poor recovery, reducing patients' quality of life and limiting medical therapy. To date, effective treatment options are lacking. Whole-body vibration (WBV) training can attenuate motor and sensory deficits. We are conducting a two-armed, multicentre, assessor-blinded, randomised controlled trial, to investigate the effects of WBV on relevant symptoms of CIPN and determine the training characteristics. METHODS AND ANALYSIS In this ongoing study, 44 patients who have completed therapy in the past 3 months, with a neurologically confirmed CIPN are assessed before and after a 12-week intervention and follow-up. The intervention group receives WBV twice a week. Exercises are individually tailored according to the initially determined optimal neuromuscular response. The control group receives care as usual.Primary endpoint is the patient reported reduction of CIPN-related symptoms (Functional Assessment of Cancer Therapy/Gynaecology Oncology Group-Neurotoxicity). Secondary endpoints are compound muscle action potentials, distal motor latency, conduction velocity, F-waves from the tibial and peroneal nerve, antidromic sensory nerve conduction studies of the sural nerve, normalised electromyographic activity, peripheral deep sensitivity, proprioception, balance, pain, the feasibility of training settings, quality of life and the level of physical activity. AIM, ETHICS AND DISSEMINATION The study was approved by both responsible ethics committees. (1) Our results may contribute to a better understanding of the effects of WBV on motor and sensory functions and (2) may provide information whether WBV at the most effective setting, is feasible for neuropathic patients. (3) Our results may also contribute to improve supportive care in oncology, thereby enhancing quality of life and enabling the optimal medical therapy. All results will be published in international peer-reviewed journals as well as a manual for clinical practice. TRIAL REGISTRATION NUMBER NCT03032718.
