The Efficacy of Acupuncture in Chemotherapy-Induced Peripheral Neuropathy: Systematic Review and Meta-Analysis

Effects of acupuncture-related intervention on chemotherapy-induced peripheral neuropathy and quality of life: An umbrella review

BACKGROUND

Numerous studies have explored the role of acupuncture-related treatments in alleviating chemotherapy-induced peripheral neuropathy (CIPN) and improving the quality of life for patients with cancer, resulting in mixed findings. This umbrella review aimed to synthesize existing systematic reviews (SRs) to deliver an updated assessment of the certainty of evidence concerning the effects of acupuncture-related treatments on CIPN and quality of life among a diverse group of patients with cancer.

METHODS

This umbrella review considered eligible SRs published on one of nine electronic databases between inception and August 2024. It included adult patients with cancer of any stage who were undergoing chemotherapy. Interventions encompassed acupuncture, either alone or with electrical stimulation or moxibustion, and transcutaneous electrical acupoint/nerve stimulation (TEAS). The outcomes analyzed were changes in CIPN, nerve conduction velocity (NCV), and quality of life.

RESULTS

The outcomes were evaluated using data obtained from 14 SRs that demonstrated moderate to high methodological and reporting quality. The findings showed that acupuncture (either alone or combined with electrical stimulation) and TEAS effectively alleviated CIPN symptoms, reduced CIPN pain, improved NCV, and enhanced quality of life.

CONCLUSION

The findings of this umbrella review indicate that these benefits were usually noticeable by the second week of treatment, persisted until the sixth week, and then gradually declined. Sensory nerve recovery occurred more rapidly than motor nerve recovery, often within 1.5 weeks. Although acupuncture combined with moxibustion or acupressure also enhanced patient outcomes, there was insufficient information available for further study analysis.

Perineural Electrical Dry Needling and Neural Mobilization for Chemotherapy-Induced Peripheral Neuropathy: Case Report

Background: Chemotherapy-induced peripheral neuropathy (CIPN) affects 20-85% of individuals exposed to neurotoxic chemotherapeutic agents. Perineural electrical dry needling (PEDN) and neural mobilization (NM) interventions may be beneficial in the management of chronic neurogenic pain; however, there is a paucity of research on the efficacy of both interventions for CIPN. Methods: Three patients were referred to an outpatient physical therapy clinic with chronic neuropathic pain associated with CIPN. Each underwent PEDN and NM twice weekly until goals were met or progress stalled. The primary outcome measure was the Numeric Pain Rating Scale (NPRS). Secondary outcomes included the Global Rating of Change (GROC) and the Lower Extremity Functional Scale (LEFS). All outcome measures were assessed at evaluation and discharge. Results: At discharge, patients A and B exceeded the minimum clinically important difference (MCID) for the primary and secondary outcome measures, indicating decreased neuropathic pain and improved lower extremity function. Patient C improved in all outcome measures but only experienced clinically meaningful changes in the NPRS and LEFS, not the GROC. Conclusions: Following 4-8 sessions of PEDN and NM, three patients with CIPN demonstrated clinically meaningful improvements in chronic lower extremity neuropathic pain and function. PEDN and NM may be beneficial in the management of patients presenting with chronic neuropathic pain secondary to CIPN.

Exploration of the quantitative-effectiveness association between acupuncture temporal parameters and chemotherapy-induced peripheral neuropathy in cancer patients: a dose-response meta-analysis of randomized controlled trials

Background

Chemotherapy-induced peripheral neuropathy (CIPN) is one of the commonly reported symptoms impacting cancer survivors. This study evaluated and compared the effectiveness of acupuncture treatments for CIPN.

Methods

We searched six databases from their inception to August 2024 to identify eligible randomized controlled trials (RCTs). Primary outcome were pain scores. Secondary outcomes were quality of life including FACT/GOG-Ntx and EORTC QLQ-C30. The robust error meta-regression (REMR) method was used to evaluate the dose-response relationship across treatment parameters, including number of sessions, frequency, and duration.

Results

In total, 11 RCTs featuring 740 participants were included. The meta-analysis demonstrated that the primary analysis achieved a significant reduction in pain scores, with a standardized mean difference of [SMD= -1.23, 95% CI = (-2.22, -0.24); P < 0.01; I² = 95%], improvement quality of life including FACT/GOG-Ntx [SMD = 0.95, 95% CI = (0.02, 1.88); P < 0.01; I² = 93%] and EORTC QLQ-C30 [SMD = 0.36, 95% CI = (0.03, 0.68); P = 0.14; I² = 46%]. The nonlinear dose-response analysis suggests that pain improvement achieves the MCID at 16 treatment sessions, over 8 weeks, with a frequency of twice per week. Furthermore, analysis of the treatment duration chart shows that acupuncture maintains therapeutic effects during the follow-up period. Sensitivity analysis confirmed the robustness of these findings.

Conclusion

Acupuncture demonstrates significant potential in managing CIPN, particularly through individualized treatment regimens. The identified time-dose-response relationship suggests that tailoring acupuncture frequency and duration can to optimize pain relief in CIPN patients. Future high-quality studies and large-scale multicenter clinical trials are needed to validate these findings.

Navigating Alternative Medicine Preferences in Palliative Care: Challenges and Collaborative Solutions

Integrating alternative medicine into palliative care presents unique opportunities and challenges for healthcare providers. This article examines two clinical cases that illustrate the complexities of navigating patient preferences for alternative therapies within evidence-based palliative care. The first case involves a 50-year-old woman with metastatic breast cancer who prioritized the use of herbal poultices and natural remedies following her faith as a Seventh-day Adventist. Despite her initial resistance to conventional treatments, the collaborative efforts of the palliative care team facilitated compromises that improved her quality of life, including the use of radiotherapy to manage bleeding and opioids for pain relief in her final days. The second case highlights a 68-year-old man with advanced pulmonary fibrosis who preferred herbal infusions in his oxygen humidifier, homeopathic remedies, and Reiki while declining opioids due to concerns about side effects. The team addressed his symptom management needs through patient-centered communication and interdisciplinary collaboration, incorporating safer alternatives and supportive therapies without compromising his values. These cases underscore the importance of balancing respect for patient autonomy with the imperative to provide safe and effective care. Key strategies include interdisciplinary collaboration, empathetic communication, and incorporating complementary therapies that align with patient values while mitigating risks. By fostering trust and maintaining flexibility, palliative care teams can effectively address the diverse needs of patients who seek alternative medicine, ensuring holistic and patient-centered care. The discussion provides actionable recommendations for integrating alternative medicine preferences into palliative care practice, emphasizing the need for ongoing education, monitoring, and collaboration to navigate these complex situations effectively.

Topical menthol for chemotherapy-induced peripheral neuropathy: a randomised controlled trial in breast cancer

OBJECTIVES

Chemotherapy-induced peripheral neuropathy (CIPN) symptom is one of the side effects of paclitaxel in breast cancer patients. This randomised controlled study was conducted to investigate the effect of topical menthol applied on the hands and feet of breast cancer patients receiving chemotherapy on CIPN symptoms.

METHODS

60 breast cancer patients receiving chemotherapy were randomly assigned to an intervention group (n=30), which received topical menthol treatment, or a control group (n=30), which received standard care. Both groups continued their routine pharmacological treatments throughout the study. The intervention group applied 1% menthol topically to their hands and feet two times a day. The effect of the intervention on CIPN symptoms was evaluated 3 weeks and 6 weeks after the intervention.

RESULTS

The intervention group showed a significantly greater improvement in CIPN symptoms over time compared with the control group, with an effect size of η2=0.214 for the group×time interaction. Additionally, the intervention group exhibited a notable positive change in the exposure subscale of the CIPN rating scale, with an effect size of η2=0.114.

CONCLUSIONS

Topical application of menthol significantly mitigates the symptoms of CIPN in breast cancer patients. This study supports the use of menthol as an effective adjunctive treatment for CIPN.

Acupuncture in the treatment of chemotherapy-induced peripheral neuropathy: a meta-analysis and data mining

Background

The efficacy and acupoint selection of acupuncture in treating chemotherapy-induced peripheral neuropathy (CIPN) remain controversial. This study aims to explore the specific efficacy and acupoint selection of acupuncture in treating CIPN through a meta-analysis and data mining.

Methods

Searching for clinical trials on acupuncture treatment for CIPN in 8 databases, evaluating its efficacy and safety through a meta-analysis, and exploring its acupoint selection through data mining.

Results

The meta-analysis included 21 studies and 2,121 patients, showing that compared with the control group, the acupuncture group could significantly improve neuropathic pain intensity (SMD = -0.66, 95% CI [-1.07, -0.25], p = 0.002), significantly reduce the NCI-CTCAE (MD = -0.29, 95%CI [-0.50, -0.08], p < 0.01), significantly reduce the FACT-NXT score (MD = 2.09, 95% CI [0.73,3.45], p < 0.05), significantly increase the motor conduction velocities (MCV) of median nerve (MD = 2.38, 95% CI [2.10, 2.67], p < 0.001), the sensory conduction velocities (SCV) of the median nerve (MD = 0.56, 95 %CI [-1.45, 2.57], p = 0.58), the SCV of the tibial nerve (MD = 1.78, 95% CI [0.50, 3.05], p < 0.01), and the SCV of sural nerves (MD = 4.60, 95% CI [0.17, 9.02], p < 0.05), as well as improving the quality of life score (MD =7.35, 95% CI [1.53, 13.18], p = 0.01). Data mining showed that the core acupoints for acupuncture treatment of CIPN were LI4, ST36, LI11, LR3, and SP6.

Conclusion

Acupuncture can improve the neuropathic pain intensity, the intensity of the CIPN, MCV of the median nerve, SCV of the tibial nerve and peroneal nerve, quality of life, and has good safety in CIPN patients. LI4 (Hegu), ST36 (Zusanli), LI11 (Quchi), LR3 (Taichong), and SP6 (Sanyinjiao) are the core acupuncture points for treating CIPN, and this protocol has the potential to become a supplementary treatment for CIPN.

Gabapentinoids for chemotherapy-induced peripheral neuropathy: systematic review and meta-analysis

INTRODUCTION

Chemotherapy-induced peripheral neuropathy (CIPN) affects patients' quality of life and treatment effectiveness. Gabapentinoids, like gabapentin and pregabalin, are often used for CIPN treatment, but their efficacy and safety remain uncertain. This study reviews and analyses randomised controlled trial data on this topic.

MATERIALS/METHODS

We searched PubMed, Embase and Cochrane CENTRAL until 29 August 2022 for studies on gabapentinoid use in CIPN. Meta-analysis was performed using RevMan V.5.4 and the Metafor package in R. Outcomes included pain scores, quality of life and adverse drug events.

RESULTS

For the prevention setting, our meta-analysis shows that pregabalin did not significantly improve average pain (standardised mean difference (SMD) -0.14, 95% CI -0.51 to 0.23; I2=26% (95% CI 0% to >98%)) or quality of life (mean difference (MD) 2.5, 95% CI -4.67 to 9.67; p=0.49) in preventing CIPN compared with placebo. However, it showed a potential trend towards reducing the worst pain (SMD -0.28, 95% CI -0.57 to 0.01; I2=0% (95% CI 0% to 98%; p=0.06)). For the treatment setting, some studies have shown a potential therapeutic effect of gabapentinoids. However, the results are not consistent between studies. Given the studies' heterogeneity, a meta-analysis in treatment setting was not performed.

CONCLUSION

There is limited evidence to support the use of gabapentinoids in CIPN. In prevention setting, gabapentinoids do not significantly prevent CIPN. In treatment setting, studies have been inconsistent in their conclusions, lacking definitive benefits over placebo. More comprehensive and higher quality research is needed in the future.

Acupuncture-related interventions improve chemotherapy-induced peripheral neuropathy: A systematic review and network meta-analysis

BACKGROUND

The previous effects of acupuncture-related interventions in improving chemotherapy-induced peripheral neuropathy (CIPN) symptoms and quality of life (QoL) remain unclear in terms of pairwise comparisons.

AIMS

This systematic review and network meta-analysis aimed to determine the hierarchical effects of acupuncture-related interventions on symptoms, pain, and QoL associated with CIPN in cancer patients undergoing chemotherapy.

METHODS

Nine electronic databases were searched, including PubMed, Embase, Cochrane Library, EBSCO, Medline Ovid, Airiti Library, China National Knowledge Infrastructure (CNKI), China Journal full-text database (CJFD), and Wanfang. Medical subject heading terms and text words were used to search for eligible randomized controlled trials published from database inception to May 2023.

RESULTS

A total of 33 studies involving 2,027 participants were included. Pairwise meta-analysis revealed that acupuncture-related interventions were superior to usual care, medication, or dietary supplements in improving CIPN symptoms, CIPN pain, and QoL. Furthermore, network meta-analysis indicated that acupuncture plus electrical stimulation (acupuncture-E) had the greatest overall effect among the various interventions. The surface under the cumulative ranking curve (SUCRA) revealed that acupuncture-E ranked the highest in improving CINP symptoms. Acupuncture alone was most effective in reducing CIPN pain, and acupuncture plus moxibustion (acupuncture-M) ranked highest in enhancing QoL.

CONCLUSION

This finding suggests that acupuncture-related interventions can provide patients with benefits in improving CIPN symptoms, pain, and QoL. In particular, acupuncture-E could be the most effective approach in which the provided evidence offers diverse options for cancer patients and healthcare professionals.

IMPLICATION FOR THE PROFESSION AND/OR PATIENT CARE

These findings provide valuable insights into the potential benefits of acupuncture-related interventions for managing symptoms, pain, and QoL associated with CIPN in patients undergoing chemotherapy. Among the various interventions studied, overall, acupuncture-E had the most significant impact and was effective for a minimum duration of 3 weeks. On the other hand, transcutaneous electrical acupoint/nerve stimulation (TEAS) was identified as a noninvasive and feasible alternative for patients who had concerns about needles or the risk of bleeding. It is recommended that TEAS interventions should be carried out for a longer period, preferably lasting 4 weeks, to achieve optimal outcomes.

TRIAL REGISTRATION

The study protocol was registered in the International Prospective Register of Systematic Reviews.

Head-to-Head Comparison of Electroacupuncture and Laser Acupuncture Effects on Autonomic Regulation and Clinical Effects in Dysmenorrhea: A Randomized Crossover Clinical Trial

Introduction: Electroacupuncture (EA) has been applied in dysmenorrhea and has shown good efficacy. The mechanisms of EA are associated with autonomic nervous system adjustments and neuroendocrine regulation. Laser acupuncture (LA), however, has been widely investigated for its noninvasiveness. However, it remains uncertain whether LA is as effective as EA. This study aimed to compare EA and LA head to head in dysmenorrhea. Methods: A crossover, randomized clinical trial was conducted. EA or LA was applied to selected acupuncture points. Participants were randomized into two sequence treatment groups who received either EA or LA twice per week in luteal phase for 3 months followed by 2-month washout, then shifted to other groups (sequence 1: EA > LA; sequence 2: LA > EA). Outcome measures were heart rate variability (HRV), prostaglandins (PGs), pain, and quality-of-life (QoL) assessment (QoL-SF12). We also compared the effect of EA and LA in low and high LF/HF (low frequency/high frequency) status. Results: Totally, 43 participants completed all treatments. Both EA and LA significantly improved HRV activity and were effective in reducing pain (Visual Analog Scale [VAS]; EA: p < 0.001 and LA: p = 0.010) and improving QoL (SF12: EA: p < 0.001, LA, p = 0.017); although without intergroup difference. EA reduced PGs significantly (p < 0.001; δ p = 0.068). In low LF/HF, EA had stronger effects than LA in increasing parasympathetic tone in respect of percentage of successive RR intervals that differ by more than 50 ms (pNN50; p = 0.053) and very low-frequency band (VLF; p = 0.035). Conclusion: There is no significant difference between EA and LA in improving autonomic nervous system dysfunction, pain, and QoL in dysmenorrhea. EA is prominent in PGs changing and preserving vagus tone in low LF/HF; yet LA is noninvasive for those who have needle phobia. Whether LA is equivalent with EA and the mechanism warrants further study. Clinical trial identification number: NCT04178226.

The Efficacy of Neuromodulation Interventions for Chemotherapy-Induced Peripheral Neuropathy: A Systematic Review and Meta-Analysis

Purpose

To determine the efficacy and safety of a neuromodulation intervention regimen in the treatment of chemotherapy-induced peripheral neuropathy (CIPN).

Patients and Methods

Systematic searches were conducted in seven English databases. Randomized controlled trials of all neuromodulation interventions (both invasive and non-invasive) for the treatment of CIPN were selected. Group comparisons of differences between interventions and controls were also made. We divided the outcomes into immediate-term effect (≤3 weeks), short-term effect (3 weeks to ≤3 months), and long-term effect (>3 months).

Results

Sixteen studies and 946 patients with CIPN were included. Among immediate-term effects, neuromodulation interventions were superior to usual care for improving pain (SMD=-0.77, 95% CI -1.07~ 0.47), FACT-Ntx (MD = 5.35, 95% CI 2.84~ 7.87), and QOL (SMD = 0.44, 95% CI 0.09~ 0.79) (moderate certainty); neuromodulation loaded with usual care was superior to usual care for improving pain (SMD=-0.47, 95% CI -0.71 ~ -0.23), and QOL (SMD = 0.40, 95% CI 0.12 ~ 0.69) (moderate certainty). There were no statistically significant differences between the neuromodulation interventions regimen vs usual care in short- and long-term outcomes and neuromodulation vs sham stimulation from any outcome measure. There were mild adverse events such as pain at the site of stimulation and bruising, and no serious adverse events were reported.

Conclusion

Neuromodulation interventions had significant immediate-term efficacy in CIPN but had not been shown to be superior to sham stimulation; short-term and long-term efficacy could not be determined because there were too few original RCTs. Moreover, there are no serious adverse effects of this therapy.

Contributions of neuroimmune interactions to chemotherapy-induced peripheral neuropathy development and its prevention/therapy

Chemotherapy-induced peripheral neuropathy (CIPN) is a debilitating sequela that is difficult for both clinicians and cancer patients to manage. Precise mechanisms of CIPN remain elusive and current clinically prescribed therapies for CIPN have limited efficacy. Recent studies have begun investigating the interactions between the peripheral and central nervous systems and the immune system. Understanding these neuroimmune interactions may shift the paradigm of elucidating CIPN mechanisms. Although the contribution of immune cells to CIPN pathogenesis represents a promising area of research, its fully defined mechanisms have not yet been established. Therefore, in this review, we will discuss (i) current shortcoming of CIPN treatments, (ii) the roles of neuroimmune interactions in CIPN development and (iii) potential neuroimmune interaction-targeting treatment strategies for CIPN. Interestingly, monocytes/macrophages in dorsal root ganglia; microglia and astrocytes in spinal cord; mast cells in skin; and Schwann cell near peripheral nerves have been identified as inducers of CIPN behaviors, whereas T cells have been found to contribute to CIPN resolution. Additionally, nerve-resident immune cells have been targeted as prevention and/or therapy for CIPN using traditional herbal medicines, small molecule inhibitors, and intravenous immunoglobulins in a preclinical setting. Overall, unveiling neuroimmune interactions associated with CIPN may ultimately reduce cancer mortality and improve cancer patients' quality of life.

Complementary and alternative medicine in relation to chemotherapy-induced peripheral neuropathy: A narrative review

PURPOSE

To summarizes the available evidence on the effectiveness, safety, and feasibility of complementary and alternative medicine (CAM) in the management of chemotherapy-induced peripheral neuropathy (CIPN).

METHODS

We searched for systematic reviews, and meta-analyzes published up to April 2023 in the Pubmed and Web of Science databases. The latest original research on related topics was also reviewed. The search was restricted to English-language papers. Two independent reviewers performed a quality assessment of the identified literature.

RESULTS

The results of 35 systematic reviews and meta-analyzes were included in this study. Preliminary evidence suggests that CAM, including acupuncture, physical activity (PA), herbal and nutritional supplements, mind-body therapies, touch therapy, and non-invasive neuromodulation techniques, have shown tremendous potential for the prevention and treatment of CIPN. Of these, there is strong evidence supporting acupuncture, PA, and herbal medicine. However, existing clinical studies are also limited by the heterogeneity of study methods, insufficient sample size, and poor study design. Further studies are needed to validate the efficacy of CAM in patients with CIPN and to elucidate potential therapeutic mechanisms.

CONCLUSIONS

Current research has reached a preliminary conclusion suggesting the potential efficacy of certain CAMs in the management of CIPN. Future clinical trials should incorporate more robust study design protocols and larger sample sizes to enhance the validity of findings.

Herbal compounds as promising therapeutic agents in precision medicine strategies for cancer: A systematic review

BACKGROUND

The field of personalized medicine has gained increasing attention in cancer care, with the aim of tailoring treatment strategies to individual patients for improved outcomes. Herbal medicine, with its long-standing historical use and extensive bioactive compounds, offers a rich source of potential treatments for various diseases, including cancer.

OBJECTIVE

To provide an overview of the current knowledge and evidence associated with incorporating herbal compounds into precision medicine strategies for cancer diseases. Additionally, to explore the general characteristics of the studies included in the analysis, focusing on their key features and trends.

SEARCH STRATEGY

A comprehensive literature search was conducted from multiple online databases, including PubMed, Scopus, Web of Science, and CINAHL-EBSCO. The search strategy was designed to identify studies related to personalized cancer medicine and herbal interventions.

INCLUSION CRITERIA

Publications pertaining to cancer research conducted through in vitro, in vivo, and clinical studies, employing natural products were included in this review.

DATA EXTRACTION AND ANALYSIS

Two review authors independently applied inclusion and inclusion criteria, data extraction, and assessments of methodological quality. The quality assessment and biases of the studies were evaluated based on modified Jadad scales. A detailed quantitative summary of the included studies is presented, providing a comprehensive description of their key features and findings.

RESULTS

A total of 121 studies were included in this review for analysis. Some of them were considered as comprehensive experimental investigations both in vitro and in vivo.

Electroacupuncture use for treatment of taxane-induced peripheral neuropathy in patients with breast cancer: protocol for a pilot, randomised, blinded, sham-controlled trial (EA for CIPN)

INTRODUCTION

Chemotherapy-induced peripheral neuropathy (CIPN) is a common dose-limiting side effect of neurotoxic chemotherapy. Acute symptoms of CIPN during treatment can lead to dose reduction and cessation. Trials using electroacupuncture (EA) to treat established CIPN postchemotherapy have shown some efficacy. The current trial aims to assess the feasibility and preliminary efficacy of using EA to treat CIPN during chemotherapy.

METHODS AND ANALYSIS

The current study is a single-centre, 1:1 randomised, sham-controlled pilot study set in a tertiary cancer hospital in Sydney, Australia, and will recruit 40 adult patients with early breast cancer undergoing adjuvant or neoadjuvant paclitaxel chemotherapy. Patients who develop CIPN within the first 6 weeks of chemotherapy will receive either true EA or sham-EA once a week for 10 weeks. The coprimary endpoints are recruitment and adherence rate, successful blinding of patients and compliance with the follow-up period. Secondary endpoints are mean change of CIPN symptoms from randomisation to end of treatment, sustained change in CIPN symptoms at 8-week and 24-week follow-up postchemotherapy, proportion of subjects attaining completion of 12 weeks of chemotherapy without dose reduction or cessation, change in acupuncture expectancy response pretreatment, during treatment and posttreatment. The primary assessment tool for the secondary endpoints will be a validated patient-reported outcome measure (European Organisation for Research and Treatment of Cancer Quality of Life Chemotherapy-Induced Peripheral Neuropathy) captured weekly from randomisation to week 12 of chemotherapy.

ETHICS AND DISSEMINATION

The study protocol (2021/ETH12123) has been approved by the institutional Human Research Ethics Committee at St Vincent's Hospital Sydney and Chris O'Brien Lifehouse. Informed consent will be obtained prior to starting study-related procedures. The results will be disseminated in peer-reviewed journals and at scientific conferences.

Current Insights into Carpal Tunnel Syndrome: Clinical Strategies for Prevention and Treatment

BACKGROUND

Carpal tunnel syndrome (CTS) is a condition that is caused by medial nerve compression, resulting in symptoms such as numbness, tightness, or weakness in the hand.

OBJECTIVES

The aim of the study was to find out the genetic modulation, mechanism, available treatment, and recommendation for carpal tunnel syndrome at its specific stage.

METHODS

Almost 200 papers were searched for this review article, and 145 articles were selected. The literature was collected from different sources like Google scholar, PubMed, a directory of open-access journals, and science.gov by using keywords, such as treatment, risk factors, recommendation, and clinical features of carpal tunnel syndrome.

RESULTS

The most efficient non-surgical treatment is methylprednisolone acetate, which reduces inflammation by acting on the glucocorticoid receptor in conjunction with immunofilling. It has also been used successfully as a second-line drug for the treatment of patients with mild or moderate conditions in order to provide relief. New non-pharmacological options include laser therapy in acupuncture, transcutaneous electric nerve stimulation (TENS), and sham therapy. Modern treatments like TENS, laser therapy, splints, and injections of methylprednisolone acetate have been demonstrated to be helpful in sporadic situations. For patients with mild and moderate problems, more research should be conducted that includes the combination of these surgical and non-surgical treatments.

CONCLUSION

We propose a multifunctional panel construct and define standard data items for future research into carpal tunnel syndrome. A discussion on idiopathic carpal tunnel syndrome, risk factors, combination of therapies, using guidelines-based recommendations and treatment should be initiated.

Non-pharmacological therapy for chemotherapy-induced peripheral neurotoxicity: a network meta-analysis of randomized controlled trials

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.

Living with chemotherapy-induced peripheral neuropathy: a nested qualitative study

BACKGROUND

Chemotherapy-induced peripheral neuropathy (CIPN) is a dose-limiting side-effect for patients undergoing a variety of chemotherapy regimens. These effects can have a detrimental impact on patients' quality of life and ability to perform everyday tasks.

OBJECTIVE

This study aimed to explore the experience of living with CIPN prior to and while participating in a randomised study of acupuncture versus a control wait group.

DESIGN

The study was nested within a randomised trial (n=120) with participants randomised to acupuncture or to control (wait list for acupuncture).

METHOD

Participants (n=23) volunteered to be interviewed either by telephone (n=20) or face to face (n=3). The audiotapes produced were transcribed verbatim and analysed using a thematic approach.

RESULTS

Four themes developed; these included daily life with CIPN, signs and symptoms, interacting with others and management of CIPN. Patients reported compromised dexterity and ability to safely carry out activities. They were often reliant on help and sought out information from others living with the condition. There were also concerns about the lack of effectiveness and the side-effects of medication prescribed.

CONCLUSION

Participants were self-selecting volunteers across different cancer groups, but the information gathered could influence future study designs and increase understanding of the impact of CIPN on patients' lives.

An umbrella review of the evidence to guide decision-making in acupuncture therapies for chemotherapy-induced peripheral neuropathy

BACKGROUND

Acupuncture therapy is believed to have therapeutic potential for patients suffering from chemotherapy-induced peripheral neuropathy (CIPN). This umbrella review aims to summarize and evaluate the evidence from current systematic reviews/meta-analyses (SRs/MAs) on the effectiveness of acupuncture treatment for CIPN.

METHODS

We conducted a comprehensive search in eight electronic databases for SRs/MAs that included RCTs on acupuncture treatment for CIPN. Two separate researchers independently evaluated the methodological quality, reporting quality, and evidence quality of the SRs/MAs that were included in the study. Additionally, we examined the extent of overlap among the included RCTs by calculating the corrected covered area (CCA). Furthermore, we assessed the dependability of the effect sizes by conducting excess significance tests. We conducted a quantitative synthesis of all RCTs included in the SRs/MAs to obtain objective and updated conclusions. Furthermore, we also conducted an analysis of the acupuncture points used in RCTs.

RESULTS

This umbrella review includes 9 SRs/MAs, and their methodological quality, risk of bias, reporting quality, and evidence quality were all deemed unsatisfactory. Out of the 9 SRs/MAs, 28 RCTs were included, with a total CCA of 25.4%, indicating a high degree of overlap. The test of super-significance did not yield any significant results. Our updated meta-analysis suggests that CIPN patients can benefit from acupuncture therapy, as indicated by effectiveness in measures including BPI-SF, VAS, FACT-NTX, NRS, SCV, and NCI-CTCAE. Egger's test and sensitivity analysis demonstrate the reliability and stability of this conclusion. The commonly used acupuncture points in the current RCTs include ST36, LI11, LI4, LR3, and SP6.

CONCLUSION

Based on the existing evidence, acupuncture is effective and safe for patients with CIPN, as it can significantly improve effective rate, pain symptoms, quality of life, and nerve conduction velocity. However, given the low quality of current evidence, we should be cautious in interpreting this conclusion.

The Effects of Complementary Therapies on Patient-Reported Outcomes: An Overview of Recent Systematic Reviews in Oncology

Many patients with cancer make use of complementary medicine alongside conventional medicine, but clinicians in oncology often lack the knowledge to adequately advise patients on the evidence base for complementary therapies. This study aims to provide an overview of recently published systematic reviews that assess the effects of complementary therapies on patient-reported health outcomes in patients with cancer. Systematic reviews, including a meta-analysis of at least two randomized controlled trials, were identified from the PubMed, Embase, Cochrane Library, CINAHL and PsycINFO databases. The methodological quality was assessed with AMSTAR 2. One hundred systematic reviews were included. The results suggest that several complementary therapies can improve health outcomes reported by patients with cancer, such as acupuncture to relieve pain, music interventions to reduce anxiety and yoga to improve cancer-related fatigue. The side effects related to complementary therapy use are generally mild. The results remain inconclusive for some intervention-outcome combinations. Many of the included systematic reviews insufficiently assessed the causes and impact of bias in their interpretation of the results. This overview of systematic reviews can support clinicians in counselling their patients on this topic and provide directions for future research and clinical practice guidelines in the field of complementary medicine.

Use of acupuncture with acupressure in addition to standard-of-care cryotherapy to decrease chemotherapy-associated neuropathy in patients with gastrointestinal malignancies receiving oxaliplatin-based chemotherapy: Study protocol for a randomized, controlled pilot and feasibility study

BACKGROUND

Oxaliplatin is a key chemotherapeutic agent in the treatment of local and metastatic gastrointestinal (GI) malignancies. Dose density and treatment adherence can be limited by chemotherapy-induced peripheral neuropathy (CIPN). Early research suggests CIPN incidence and severity may be mitigated by acupuncture, but rigorous data in GI oncology patients is limited. Here, we describe the protocol of a randomized, waitlist-controlled pilot study testing the use of preemptive of acupuncture plus acupressure to decrease CIPN and chemotherapy-related toxicities.

METHODS

Patients with a GI malignancy (n = 56) with planned 5-fluorouracil (5-FU) and oxaliplatin IV (FOLFOX, FOLFIRINOX) every 2 weeks are being recruited. Additional concurrent anti-neoplastic agents may be used. Enrolled patients are randomized 1:1 to a 3-month intervention of Arm A: acupuncture with acupressure and standard-of-care treatment, or Arm B: standard-of-care alone. In Arm A, on days 1 and 3 of each chemotherapy cycle a standardized acupuncture protocol is administered and patients are taught self-acupressure to perform daily between chemotherapy treatments. Patients in both arms are given standard-of-care oral and peripheral (hands/feet) ice chip cryotherapy during oxaliplatin administration. CIPN and other symptoms are assessed at baseline, 6 weeks, and 3 months from registration. The primary endpoint is CIPN severity at 3 months (EORTC-CIPN 20). Additional endpoints evaluate CIPN incidence (CTCAE, Neuropen, tuning fork); incidence of pain, fatigue, nausea, oral dysesthesia, and anxiety; and feasibility (recruitment, retention, adherence, acceptability). If warranted, trial results will inform the design of a multi-center trial to expand testing of the intervention to a larger patient cohort.

Acupuncture effect on dumping syndrome in esophagus cancer patients with feeding jejunostomy: A study protocol for a single blind randomized control trial

INTRODUCTION

Esophagus cancer patients are at risk for malnourishment. Feeding jejunostomy is used in advanced esophagus cancer patients in order to support and supplement the patients' nutrition needs. In dumping syndrome, the food is rapidly introduced into the intestine at a rate that is faster than normal, it is associated with both digestive system and vasoactive symptoms. Dumping syndrome has an association with both esophagus cancer patients and feeding jejunostomy. In the mid and long term, dumping syndrome is an important issue that contributes to the risk of malnourishment in advanced esophagus cancer patients. In recent studies, acupuncture was effective in regulating digestive symptoms. Acupuncture is considered to be a safe intervention, that was previously shown to be effective in treating digestive-related symptoms.

METHODS

Sixty advanced esophageal cancer patients post-feeding jejunostomy will be divided into 2 equal groups, an intervention group (n = 30) and a control group (n = 30). Patients in the intervention group will receive acupuncture using the following acupoints: ST36 (Zusanli), ST37 (Shangjuxu), ST39 (Xiajuxu), PC6 (Neiguan), LI4 (Hegu), and Liv 3 (Taichung). Patients in the control group will receive shallow acupuncture on 12 non-acupoints (sham points), 1 cm from the above mention points. Patients and assessors will be blind to trial allocation. Both groups will receive acupuncture twice a week for 6 weeks. The main outcome measurements are: body weight, BMI, Sigstad's score, and the Arts' dumping questionnaire.

DISCUSSION

There are no previous studies that have examined the use of acupuncture on patients with dumping syndrome. This single-blind randomized control trial will investigate the effect of acupuncture on dumping syndrome in advanced esophagus cancer patients with feeding jejunostomy. The results will determine if verum acupuncture can affect dumping syndrome and prevent weight loss.

The Holistic Philosophy of Traditional Chinese Medicine and Conflicts With Modern Medicine

Traditional Chinese medicine (TCM) has sparked the public's attention for its potential in new drug development and its holistic view toward health, which is totally different from the reductionistic science of modern medicine. Although many scholars try to connect TCM with precision medicine or apply new methods and technology to integrate TCM with modern medicine, the misunderstandings and gap between TCM and modern medicine limit the development of evidence-based TCM. Traditional Chinese medicine is actually a medical science encompassing not only medicine but also philosophy and art in direct contrast to molecular-based modern medicine. As more and more multidisciplinary studies are being published, finding ways to integrate TCM with modern or precision medicine through artificial intelligence, new study design and technology may become a critical issue. This article aims to briefly review the unique philosophy of TCM and its conflicts with modern medicine, with a focus on the potential integration of TCM and modern medicine. We also provide insight for the key attributes of TCM and the associated investigation with Western research approaches.

Bibliometric Analysis of Acupuncture Therapy for Cancer Pain Over the Past 10 Years

PURPOSE

Cancer pain is a common symptom of cancer patients and greatly affects quality of life. Acupuncture has certain curative effects on cancer pain. The aim of this study was to analyze and visualize the current status and research trend of acupuncture treatment for cancer pain over the last 10 years and provide directions for future development.

METHODS

A search of the Web of Science Core Collection from 2012-01-01 to 2022-08-20 was performed to collect studies related to acupuncture therapy for cancer pain. CiteSpace was used to conduct bibliometric analysis and visualization from the perspective of the volume of annual publications, journals, nations, institutions, authors, keywords, and references.

RESULTS

A total of 302 studies were included in the analysis. The number of publications increased steadily with some fluctuations over the past decade. Integrative Cancer Therapies was the journal with the most relevant publications, and the Journal of Clinical Oncology was the most frequently cited journal. China had the highest volume of publications, and the USA contributed most to international collaboration. The most prolific institution was Memorial Sloan Kettering Cancer Center. The most productive author was Mao JJ, and the most influential author was Lu WD. "Acupuncture" was the top keyword in frequency and centrality. The references with the highest frequency and centrality were published by HE, Y, and Ting Bao, respectively.

CONCLUSION

A stable development trend has formed in this field. The overall collaborative network needs to be strengthened. Breast cancer and multiple myeloma, electroacupuncture and bee venom acupuncture, postoperative pain, peripheral neuropathic pain syndrome, and aromatase inhibitors-associated arthralgia syndrome are research hotspots in this field. Randomized controlled trials (RCTs), evidence-based evaluations and mechanisms (cancer-induced bone pain) are research trends and frontiers.

Data mining analysis reveals key acupoints and meridians for the treatment of chemotherapy-induced peripheral neuropathy

OBJECTIVE

To explore effective acupoints and combinations for the treatment of chemotherapy-induced peripheral neuropathy (CIPN) METHODS: Clinical controlled trials and randomized controlled trials of acupuncture for CIPN were sourced from PubMed, Embase, Web of Science, and Chinese databases, including the Wanfang database, VIP Journals database, and China National Knowledge Infrastructure database. The quality of eligible research was evaluated based on CONSORT and STRICTA statements. The common acupoints, meridians, and acupoint combinations were determined from acupuncture prescriptions reporting positive effects and were analyzed using SPSS 23.0 and SPSS Modeler 14.1. Finally, a complex network was constructed using Cytoscape 3.8.2 to explore the core acupoints.

RESULTS

The quality of 24 clinical trials was evaluated, and 20 acupuncture prescriptions that reported positive outcomes were included in subsequent data mining analysis. The most frequently used acupoints are ST36, LI11, LI4, LR3, and SP6. Meanwhile, they are also the core acupoints in acupuncture prescriptions according to the complex network with 28 nodes and 177 edges. The most commonly used meridians were the large intestine, stomach, and spleen. Acupoint combinations of LI11 and ST36, SP6 and ST36 were frequently used.

CONCLUSION

Our study provides a reference for the selection of effective acupoints for CIPN treatment and a basis for the effective use of this form of traditional Chinese medicine. Furthermore, we found limitations in the design and implementation of the available clinical research, which should be minimized in future studies.

Integrative Medicine for Pain Management in Oncology: Society for Integrative Oncology-ASCO Guideline

PURPOSE

The aim of this joint guideline is to provide evidence-based recommendations to practicing physicians and other health care providers on integrative approaches to managing pain in patients with cancer.

METHODS

The Society for Integrative Oncology and ASCO convened an expert panel of integrative oncology, medical oncology, radiation oncology, surgical oncology, palliative oncology, social sciences, mind-body medicine, nursing, and patient advocacy representatives. The literature search included systematic reviews, meta-analyses, and randomized controlled trials published from 1990 through 2021. Outcomes of interest included pain intensity, symptom relief, and adverse events. Expert panel members used this evidence and informal consensus to develop evidence-based guideline recommendations.

RESULTS

The literature search identified 227 relevant studies to inform the evidence base for this guideline.

RECOMMENDATIONS

Among adult patients, acupuncture should be recommended for aromatase inhibitor-related joint pain. Acupuncture or reflexology or acupressure may be recommended for general cancer pain or musculoskeletal pain. Hypnosis may be recommended to patients who experience procedural pain. Massage may be recommended to patients experiencing pain during palliative or hospice care. These recommendations are based on an intermediate level of evidence, benefit outweighing risk, and with moderate strength of recommendation. The quality of evidence for other mind-body interventions or natural products for pain is either low or inconclusive. There is insufficient or inconclusive evidence to make recommendations for pediatric patients. More research is needed to better characterize the role of integrative medicine interventions in the care of patients with cancer.Additional information is available at https://integrativeonc.org/practice-guidelines/guidelines and www.asco.org/survivorship-guidelines.

Acupuncture for cancer-related conditions: An overview of systematic reviews

BACKGROUND

Acupuncture is commonly used for cancer-related conditions worldwide, and evidence is increasing year on year. There is a need to summarize the evidence of acupuncture for cancer-related conditions comprehensively and critically.

OBJECTIVE

To evaluate and summarize the systematic reviews (SRs) that assess the effects and safety of acupuncture for cancer-related conditions, and to inform clinical practice and future studies.

METHODS

A comprehensive search was conducted on Pubmed, Embase, the Cochrane Library, Web of Science, CNKI, VIP, Sinomed, and Wanfang from their inception to October 16, 2021. SRs of randomized controlled trials (RCTs) on acupuncture for cancer-related conditions were to be included. Two reviewers screened the eligible articles, and four reviewers in pair extracted data and assessed the methodological quality/risk of bias of all included reviews by AMSTAR 2 and ROBIS tools. The overlap of primary studies was measured by calculating corrected covered areas. Data from the included reviews were synthesized with a summary of meta-analysis or narrative description.

RESULTS

Fifty-one SRs of RCTs on acupuncture for cancer-related conditions were included and synthesized. The methodological quality of SRs included 1 "high", 5 "low" and 45 "very low" by AMSTAR 2. Sixteen SRs assessed as low risk of bias (31.37%), and 35 SRs had high risk of bias (68.63%) by ROBIS. Acupuncture showed effective on systemic conditions in relation to different cancers, including cancer-related pain (17 SRs, 80 RCTs), fatigue (7 SRs, 18 RCTs), insomnia (4 SRs, 10 RCTs), quality of life (2 SRs, 15 RCTs); conditions in relation to chemo-radiotherapy, including nausea and vomiting (3 SRs, 36 RCTs) and bone marrow suppression (2 SRs, 21 RCTs); and conditions in relation to specific cancers, including breast cancer-related menopause (3 SRs, 6 RCTs), hot flashes (12 SRs, 13 RCTs), arthralgia (5 SRs, 10 RCTs), and nasopharyngeal cancer-related dysphagia (1 SRs, 7 RCTs). Acupuncture appeared to have benefit for patients with lymphoedema (3 SRs, 3 RCTs), gastrointestinal function (5 SRs, 27 RCTs), and xerostomia (4 SRs, 7 RCTs). Limited evidence showed inconsistent results on acupuncture for chemotherapy-induced peripheral neuropathy (3 SRs, 6 RCTs), depression and anxiety (3 SRs, 9 RCTs). Acupuncture was regarded as a safe therapy for cancer patients as no severe adverse events related were reported.

CONCLUSION

Evidence from SRs showed that acupuncture is beneficial to cancer survivors with cancer-related pain, fatigue, insomnia, improved quality of life, nausea and vomiting, bone marrow suppression, menopausal symptoms, arthralgia, and dysphagia, and may also be potential for lymphoedema, gastrointestinal function, and xerostomia. For neuropathy, depression and anxiety, acupuncture should be used as an option based on individual conditions. Acupuncture is relatively safe without serious adverse events. More well-designed clinical trials of acupuncture are recommended on cancer-related depression and anxiety, arthralgia, xerostomia, gastrointestinal dysfunction and dysphagia.

Acupuncture in hematologic malignancies and hematopoietic cell transplantation

Acupuncture is an integrative medicine modality that has been used historically and studied recently for managing various symptoms and diseases. Patients with hematological malignancies often experience a high symptom burden including pain, fatigue, nausea, vomiting, and insomnia. Pharmacological interventions are the mainstay of managing these symptoms, although they may not provide adequate control or are not well tolerated due to side effects. There have been many randomized controlled trials of acupuncture on reduction of these symptoms. In this review, we will summarize the current evidence on the effect of acupuncture on the management of common symptoms experienced by patients with hematological malignancies and the current understanding of acupuncture's mechanism of action. The evidence is the strongest for reducing pain and nausea vomiting, less strong for symptoms such as peripheral neuropathy, fatigue, constipation, insomnia, night sweat, and pruritus.

Research Hotspots and Trends on Acupuncture for Neuropathic Pain: A Bibliometric Analysis from 2002 to 2021

Purpose

In this study, we aimed to systematically determine the trend, research hotspots, and directions of the future development of acupuncture for neuropathic pain (NP) by bibliometric analysis.

Methods

Based on the relevant literature on acupuncture for NP in the databases of Web of Science from January 2002 to December 2021, Citespace software and VOSviewer were used to determine the use of acupuncture for the treatment of NP. The annual publications, countries, authors, research institutions, keywords, co-cited references, and journals were analyzed to explore the research hotspot and development trends in this field.

Results

A total of 1462 records of acupuncture for NP from 2002 to 2021 were obtained. Chingliang Hsieh (20) is the most effective author and Han JS (585 co-citations) is the most influential author. The most productive institutions and countries are Kyung Hee UNIV (88) and China, respectively (480). UNIV Maryland of the USA has the highest centrality (0.12). Evidence-based complementary and alternative medicine (89) is the most prolific journal, and Pain is the most influential journal (4200 co-citations). Ji-sheng Han (2003) is the most frequently cited article (158 co-citations). Electroacupuncture, bee-venom acupuncture, and percutaneous electrical stimulation are the most commonly studied acupuncture types. The analgesic mechanism of acupuncture and acupuncture-neuroimaging was a research hotspot over the years. The clinical evidence of acupuncture for NP should be further studied in the future.

Conclusion

The study using bibliometric analysis methods to investigate the publications on acupuncture for NP so as to provide potential research directions in the future.

The effectiveness and safety of acupuncture for chemotherapy-induced peripheral neuropathy: A systematic review and meta-analysis

Objectives

This systematic review and meta-analysis aimed to evaluate the effectiveness and safety of acupuncture on chemotherapy-induced peripheral neuropathy (CIPN).

Methods

We searched for relevant randomized controlled trials (RCTs) in PubMed, Cochrane Library, and Embase databases from their inception to 1 April 2022. The Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity (FACT/GOG-Ntx), Brief Pain Inventory-Short Form (BPI-SF), the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core30 (EORTC QLQ-C30), Numerical Rating Scale (NRS), and adverse events were the outcome measures. All studies had at least one of these outcome measures. Mean differences (MDs) with 95% confidence intervals (CIs) were assessed in the meta-analysis using the RevMan 5.3 software.

Results

Five studies were included in the analysis. The results showed that acupuncture and placebo acupuncture were not significantly different in reducing chemotherapy-induced neurotoxicity and functional disability (random-effects estimates; MD: 4.30; 95% CI: −0.85~9.45; P = 0.10; I² = 74%). Acupuncture was better than placebo acupuncture in reducing pain severity and pain interference with patients' daily function (fixed-effect estimates; MD: −1.14; 95% CI: 1.87 to −0.42; P = 0.002; I² = 13%). Acupuncture was not significantly different from placebo acupuncture in relieving CIPN symptoms (MD: −0.81; 95% CI: −2.02 to 0.40, P = 0.19). Acupuncture improved quality of life better than placebo acupuncture (MD: 10.10; 95% CI: 12.34 to 17.86, P = 0.01). No severe adverse events were recorded in all five studies.

Conclusion

This meta-analysis suggests that acupuncture may be more effective and safer in reducing pain severity and pain interference with patients' daily function than placebo acupuncture. Additionally, acupuncture may improve the quality of life of patients with CIPN. However, large sample size studies are needed to confirm this conclusion.

A randomised, pragmatic clinical trial of ACUpuncture plus standard care versus standard care alone FOr Chemotherapy Induced peripheral Neuropathy (ACUFOCIN)

PURPOSE

Chemotherapy-induced peripheral neuropathy (CIPN) is a dose limiting toxicity posing a major clinical challenge for managing patients receiving specific chemotherapy regimens (e.g., Taxanes). There is a growing body of literature suggesting acupuncture can improve CIPN symptoms. The purpose of the ACUFOCIN trial was to collect preliminary data on the safety, feasibility, acceptability and initial effectiveness of acupuncture as a treatment for CIPN, comparing use of acupuncture plus standard care (Acupuncture) against standard care alone (Control).

METHOD

At a tertiary cancer centre, a pragmatic, randomised, parallel group design study was used to investigate the effectiveness of a 10-week course of acupuncture. Participants experiencing CIPN of ≥ Grade II, recording a 'Most Troublesome' CIPN symptom score of ≥3 using the "Measure Yourself Medical Outcome Profile" (MYMOP 2), were randomised to 'Acupuncture' or 'Control' arms. Clinicians were blinded to allocated groups, however as it was not possible to blind participants, it cannot be guaranteed they did not disclose study allocation within their clinic assessments. The primary outcome measure was the number of patients reporting a ≥ 2-point improvement (success) in their MYMOP2 score at week 10. 100 participants (120 to allow for attrition) were required for a hypothesised improvement in success proportions from 30% to 55% using a primary analysis model with logistic regression adjusted for stratification factors and baseline MYMOP2 scores. Feasibility and acceptability of study design was addressed through percentage return of primary outcome, retention rate and a nested qualitative study.

RESULTS

Primary MYMOP2 outcome data at week 10 was available for 108/120 randomised participants; this is greater than the 100 participants required to adequately power the study. There were 36/53 (68%) successes in 'Acupuncture' compared to 18/55 (33%) in 'Control'. Beneficial effects were seen in the secondary outcome data, including clinicians' grading of neuropathy, EORTC, QLQ-CIPN20, QLQ-C30 summary scores and patient reported pain scores. There were no serious adverse events reported within the study and only 16 acupuncture associated events, none of which required intervention.

CONCLUSION

A 10-week course of acupuncture resulted in measurable improvement in participants symptoms of CIPN. The results warrant further investigation.

Role of Inflammation, Oxidative Stress, and Mitochondrial Changes in Premenstrual Psychosomatic Behavioral Symptoms with Anti-Inflammatory, Antioxidant Herbs, and Nutritional Supplements

Premenstrual syndrome (PMS) significantly lowers the quality of life and impairs personal and social relationships in reproductive-age women. Some recommendations are that inappropriate oxidative stress and inflammatory response are involved in PMS. Various nutritional supplements and herbs showed neuro-psycho-pharmacological activity with antioxidant and anti-inflammatory properties. This study aims to determine the systematic review of randomized controlled trials (RCTs) of herbal medicine and nutritional supplements in PMS. We also comprehensively highlighted the role of oxidative stress, inflammation, and mitochondrial changes on PMS with the application of computational intelligence. We used PRISMA and research question-based techniques to collect the data for evaluation of our study on different databases such as Scopus, PubMed, and PROSPERO from 1990 to 2022. The methodological quality of the published study was assessed by the modified Jadad scale. In addition, we used network visualization and word cloud techniques to find the closest terms of the study based on previous publications. While we also used computational intelligence techniques to give the idea for the classification of experimental data from PMS. We found 25 randomized controlled studies with 1949 participants (mean ± SD: 77.96 ± 22.753) using the PRISMA technique, and all were high-quality studies. We also extracted the closest terms related to our study using network visualization techniques. This work has revealed the future direction and research gap on the role of oxidative stress and inflammation in PMS. In vitro and in vivo studies showed that bioactive molecules such as curcumin, allicin, anethole, thymoquinone, cyanidin 3-glucoside, gamma-linoleic acid, and various molecules not only have antioxidant and anti-inflammatory properties but also other various activities such as GABA-A receptor agonist, serotonergic, antidepressant, sedative, and analgesic. Traditional Unani Herbal medicine and nutritional supplements can effectively relieve PMS symptoms as they possess many bioactive molecules that are pharmacologically proven for the aforementioned properties. Hence, these biomolecules might influence a complex physical and psychological disease process like PMS. However, more rigorous research studies are recommended for in-depth knowledge of the efficacy of bioactive molecules on premenstrual syndrome in clinical trials.

Pharmacological and Nonpharmacological Management of Chemotherapy-Induced Peripheral Neuropathy: A Scoping Review of Randomized Controlled Trials

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.

Clinical Efficacy and Potential Mechanisms of Acupoint Stimulation Combined With Chemotherapy in Combating Cancer: A Review and Prospects

Although chemotherapy is the first-line treatment strategy for a variety of tumors, its side effects have limited its efficacy. This review summarizes the progress on the use of acupoint stimulation to combat chemotherapy-associated side effects, including chemotherapy-induced peripheral neuropathy (CIPN), cognitive impairment (CICI), and gastrointestinal toxicity (GI), as well as myelosuppression and immunosuppression. It was found that acupoint stimulation attenuated CIPN and GI by modulating the 5-hydroxytryptamine system in dorsal root ganglia, the dorsal horn of the spinal cord, and the duodenum by reducing oxidative stress and neuroinflammation. Acupoint stimulation also alleviated GI by activating vagal activity in the nucleus tractus solitarius and promoting the secretion of gastrointestinal neuropeptide hormones. Acupoint stimulation restored both bone marrow hematopoiesis and immune function to combat cancer. In addition, the combination of acupoint stimulation and chemotherapy could inhibit tumor growth by promoting tumor cell apoptosis and the enrichment of chemotherapeutic agents in tumor tissue and by modulating the tumor immune microenvironment and normalizing the vasculature. Multiple evidence also indicates that neuroimmune regulation may be involved in the effects of acupoint stimulation. In conclusion, the evidence suggests that acupoint stimulation can alleviate the side effects of chemotherapy and can also assist chemotherapeutic agents in inhibiting tumor growth, which expands the clinical application of acupoint stimulation in cancer treatment. However, more high-quality clinical studies are needed to confirm the clinical value of acupoint stimulation.

Oral Administration of East Asian Herbal Medicine for Peripheral Neuropathy: A Systematic Review and Meta-Analysis with Association Rule Analysis to Identify Core Herb Combinations

This review aimed to comprehensively assess the efficacy and safety of oral East Asian herbal medicine (EAHM) for overall peripheral neuropathy (PN). In addition, an Apriori algorithm-based association rule analysis was performed to identify the core herb combination, thereby further generating useful hypotheses for subsequent drug discovery. A total of 10 databases were searched electronically from inception to July 2021. Randomized clinical trials (RCTs) comparing EAHM with conventional analgesic medication or usual care for managing PN were included. The RCT quality was appraised using RoB 2.0, and the random effects model was used to calculate the effect sizes of the included RCTs. The overall quality of evidence was evaluated according to the Grading of Recommendations Assessment, Development, and Evaluation. By analyzing the constituent herb data, the potential association rules of core herb combinations were explored. A total of 67 RCTs involving 5753 patients were included in this systematic review. In a meta-analysis, EAHM monotherapy and combined EAHM and western medicine therapy demonstrated substantially improved sensory nerve conduction velocity, motor nerve conduction velocity, and response rate. Moreover, EAHM significantly improved the incidence rate, pain intensity, Toronto clinical scoring system, and Michigan diabetic neuropathy score. The evidence grade was moderate to low due to the substantial heterogeneity among the studies. Nine association rules were identified by performing the association rule analysis on the extraction data of 156 EAHM herbs. Therefore, the constituents of the herb combinations with consistent association rules were Astragali Radix, Cinnamomi Ramulus, and Spatholobi Calulis. This meta-analysis supports the hypothesis that EAHM monotherapy and combined therapy may be beneficial for PN patients, and follow-up research should be conducted to confirm the precise action target of the core herb.

Oral administration of East Asian herbal medicine for peripheral neuropathy: A protocol for systematic review and meta-analysis with using association rule analysis to identify core herb pattern

BACKGROUND

Peripheral neuropathy (PN) is one of the most common medical problems encountered. Since the pathophysiology and symptom manifestation characteristics of PN are very diverse, it is difficult to provide an appropriate treatment. East Asian herbal medicine (EAHM) has long contributed to the treatment of neurological and pain disorders. The goal of this systematic review is to measure the efficacy and safety of EAHM for PN and to identify core herb patterns. In order to derive a more conservative result, a random effect model will be applied regardless of the significance of heterogeneity.

METHODS

We will search 10 databases to identify suitable studies. There will be no restrictions regarding language or publication date. Primary outcomes will be nerve conduction velocity and response rate. Secondary outcomes will be any objective tool that can measure the efficacy of EAHM, and adverse events will be included. We will perform a meta-analysis of trials with the same intervention and outcome with comparator in a similar population. Meanwhile, in order to explore significant potential correlation in herb preparation, association rule analysis based on the Apriori algorithm will be performed on the collected composition data of herbal medicines.

RESULTS

This study will provide scientific evidence for the treatment of EAHM for PN.

CONCLUSIONS

Based on the results of this review, it is expected that the efficacy and safety of EAHM for PN can be confirmed. In addition, through additional analysis using data mining techniques, it will be possible to present a core herb pattern related to this research topic.

Research Trends of Acupuncture Therapy on Cancer Over the Past Two Decades: A Bibliometric Analysis

Purpose:

Acupuncture has been used for managing cancer-related symptoms. However, there are still few studies concerning the overall trends in acupuncture therapy on cancer based on bibliometric analysis. This study aims to demonstrate the current status and trends in this field over the past 2 decades.

Methods:

Articles were retrieved from the Web of Science from 2000 to 2019. CiteSpace was used for co-authorship network of countries/institutions, dual-map analysis, and detecting the keywords with citation bursts. VOSviewer was used to construct networks based on co-authorship and co-citation analysis of authors, and co-occurrence of keywords.

Results:

A total of 927 articles and reviews were included in the final analysis. The number of publications has steadily increased with some fluctuations among years. The country and institution contributing most to this field are the USA and Memorial Sloan Kettering Cancer Center. Mao JJ was the most productive author and Molassiotis A ranked first in the cited authors. The co-occurrence analysis revealed 5 clusters (including “clinical trials,” “clinical studies on chemotherapy/radiation-induced symptoms,” “CAM therapy for cancer,” “clinical studies on vasomotor symptoms,” and “systematic reviews”). Most recent keyword bursts were “neuropathic pain,” “arthralgia,” “prevention,” “supportive care,” and “integrative medicine”.

Conclusions:

The annual publication output would increase rapidly in the next decade, which shows a promising future in this research field. Future research hotspots would focus on the role of acupuncture in neuropathic pain, arthralgia, prevention, supportive care, and integrative medicine.

The effects of exercise on chemotherapy-induced peripheral neuropathy symptoms in cancer patients: a systematic review and meta-analysis

PURPOSE

To conduct a systematic review and meta-analysis of current studies to determine whether exercise affects chemotherapy-induced peripheral neuropathy (CIPN) symptoms in cancer patients.

DESIGN

The Medline, Embase, Cochrane Library, CINAHL, PubMed, and National Central Library databases, and the reference lists of the included studies were surveyed. The Consolidated Standards of Reporting Trials (CONSORT) extension checklist for non-pharmacologic treatment was used to evaluate the literature.

SETTING AND PARTICIPANTS

Exercise interventions offered in hospitals or at home. A total of 178 participants from 5 studies were assessed in the meta-analysis, with their mean age ranging from 48.56 to 71.82 years.

METHODS

The randomized control trials were summarized in a systematic review. The effects of the exercise interventions were compiled for meta-analysis. A forest plot was constructed using a fixed effect model to obtain a pooled mean difference.

RESULTS

The pooled results indicated that exercise interventions significantly improved the CIPN symptoms of the participants (mean difference: 0.5319; 95% confidence interval: 0.2295 to 0.8344; Z = 3.45; P = 0.0006). A combination of exercise protocols including a nerve gliding exercise intervention was found to have improved CIPN symptoms. In addition, a sensorimotor-based exercise intervention was found to have reduced CIPN-induced loss of postural stability.

CONCLUSIONS AND IMPLICATIONS

The findings indicated that the effects of exercise could improve CIPN symptoms in cancer patients. Nevertheless, further investigations of different exercise protocols and intensity of intervention utilizing larger sample sizes and more specific outcome measures will further inform the best practices for cancer patients.

Peripheral Neuropathy under Oncologic Therapies: A Literature Review on Pathogenetic Mechanisms

Peripheral neurologic complications are frequent adverse events during oncologic treatments and often lead to dose reduction, administration delays with time elongation of the therapeutic plan and, not least, worsening of patients’ quality of life. Experience skills are required to recognize symptoms and clinical evidences and the collaboration between different health professionals, in particular oncologists and hospital pharmacists, grants a correct management of this undesirable occurrence. Some classes of drugs (platinates, vinca alkaloids, taxanes) typically develop this kind of side effect, but the genesis of chemotherapy-induced peripheral neuropathy is not linked to a single mechanism. This paper aims from one side at summarizing and explaining all the scattering mechanisms of chemotherapy-induced peripheral neuropathy through a detailed literature revision, on the other side at finding new approaches to possible treatments, in order to facilitate the collaboration between oncologists, hematologists and hospital pharmacists.

Integrative Oncology Education: An Emerging Competency for Oncology Providers

A growing number of cancer patients use complementary and alternative therapies during and after conventional cancer treatment. Patients are often reluctant to discuss these therapies with their oncologist, and oncologists may have limited knowledge and confidence on how to advise patients on the appropriate use. Integrative oncology is a patient-centered, evidence-informed field that utilizes mind-body practices, lifestyle modifications and/or natural products interwoven with conventional cancer treatment. It prioritizes safety and best available evidence to offer appropriate interventions alongside conventional care. There are few opportunities for oncologists to learn about integrative oncology. In this commentary, we highlight the Integrative Oncology Scholars (IOS) program as a means to increase competency in this growing field. We provide an overview of several integrative oncology modalities that are taught through this program, including lifestyle modifications, physical activity, and mind-body interventions. We conclude that as more evidence is generated in this field, it will be essential that oncology healthcare providers are aware of the prevalent use of these modalities by their patients and cancer centers include Integrative Oncology trained physicians and other healthcare professionals in their team to discuss and recommend evidence-based integrative oncology therapies alongside conventional cancer treatments to their patients.

Evaluating Acupuncture for the Treatment of Chemotherapy-induced Peripheral Neuropathy: An Integrative Review

The purpose of this integrative review of the literature is to synthesize the current evidence and identify gaps in knowledge regarding the effectiveness of acupuncture to treat chemotherapy-induced peripheral neuropathy (CIPN). PubMed, CINAHL, Web of Science, and Cochrane Review databases were searched using inclusion criteria: keywords acupuncture, cancer, and peripheral neuropathy, published in English, between 2009 and 2019. Sixteen articles met the inclusion criteria. The literature indicates that acupuncture is generally well tolerated by patients with cancer, and a majority of patients with CIPN reported decreased pain and increased quality of life after receiving acupuncture treatment. A comprehensive understanding of the ability of acupuncture to treat CIPN is limited by variability of acupuncture techniques and inconsistency in measures of evaluation.

Integrative Therapies in Cancer Pain

Integrative medicine is an approach to medical care that embraces all effective therapies including complementary treatments such as acupuncture and hypnosis. There is growing use of complementary therapies in the cancer patient population, making it important that health care providers be aware of both the risks and benefits of treatments that lie outside of the traditional allopathic medicine paradigm. This chapter will explore some of the most common and well-investigated complementary therapies for the treatment and prevention of cancer-related pain. This will include discussions of: acupuncture, dietary supplements, massage, guided imagery and cryotherapy among others. The goal of this is to provide a framework for discussions between medical providers and their patients to ensure safety, discussion of all available treatments, and to facilitate open lines of communication.

Effectiveness of Acupuncture Treatment on Chemotherapy-Induced Peripheral Neuropathy: A Pilot, Randomized, Assessor-Blinded, Controlled Trial

Objective

This pilot study aims to evaluate the effectiveness and safety of acupuncture in the treatment of chemotherapy-induced peripheral neuropathy (CIPN).

Methods

This study was a pilot randomized controlled trial, which was conducted with cooperation between Beijing University of Chinese Medicine (BUCM), China, and Tehran University of Medical Science (TUMS), Iran. Forty participants with CIPN were randomly assigned (1 : 1) to receive twelve sessions of acupuncture (20 minutes each session over 4 weeks) or take one 300 mg tablet of vitamin B1 and three 300 mg capsules of gabapentin per day for 4 weeks, after which both groups were followed up for 4 weeks. The primary endpoint was CIPN symptom severity measured by the Numerical Rating Scale (NRS). The secondary endpoints included sensory neuropathy grade evaluated by the National Cancer Institute-Common Toxicity Criteria for Adverse Events (NCI-CTCAE), neurophysiological assessment of CIPN by the nerve conduction study (NCS), and the patient overall satisfaction with treatment. Safety was assessed at each visit.

Results

The NRS and NCI-CTCAE sensory neuropathy grading scales decreased significantly over time in both groups (both P < 0.001), with a significantly higher reduction in the acupuncture group (P < 0.001 and P = 0.03, respectively). In addition, the acupuncture group showed a higher overall satisfaction with the treatment at the end of treatment and after 4 weeks follow-up, in comparison with the vit B1 and gabapentin group (P = 0.01 and P = 0.001, respectively). The NCS (except for the latency of the sural nerve) in the acupuncture group improved significantly (P < 0.05), while improvement in the vit B1 and gabapentin group was not observed (P > 0.05).

Conclusion

Our study revealed that acupuncture, as a kind of traditional Chinese therapeutic method, is significantly effective and safe in the treatment of CIPN. Moreover, acupuncture is more effective than using vitamin B1 and gabapentin as the conventional treatment. Trial registration. This trial is registered with the Iranian Registry of Clinical Trials (IRCT20190615043900N1).
