Comparative efficacy of different acupuncture therapies on cancer-related insomnia: protocol for a systematic review and network meta-analysis

Exploring the mechanisms and current status of acupuncture in alleviating tumor metabolism and associated diseases: Insights from the central nervous system and immune microenvironment

Acupuncture, as a traditional Chinese medical treatment, has garnered increasing attention in recent years in fields such as tumor metabolism, the central nervous system, and the immune microenvironment. This paper aims to explore the fundamental principles, mechanisms, and research status of acupuncture therapy for tumor-related diseases. Firstly, we introduce the basic principles of acupuncture therapy, including the theories of meridians and its theoretical basis in tumor treatment. Secondly, we systematically review the mechanisms of acupuncture therapy for tumor-related diseases, discussing how acupuncture alleviates side effects such as pain, depression, fatigue, and gastrointestinal discomfort caused by conventional treatments through modulation of the immune microenvironment, central nervous system, and endocrine system. Subsequently, we discuss the current research status of acupuncture therapy for tumor-related diseases, as well as the application of current research methods and technologies in elucidating acupuncture mechanisms. Additionally, by combining clinical practice with different types of tumor-related diseases as experimental subjects, we demonstrate the application effectiveness and clinical practice experience of acupuncture in tumor treatment. Finally, a comprehensive assessment of acupuncture therapy for tumor-related diseases is provided, summarizing its limitations and prospecting future directions, including interdisciplinary collaboration and personalized treatment. In conclusion, acupuncture, as a feasible adjunctive therapy, is closely related to the central nervous system and the immune microenvironment, holding potential significant value in tumor treatment.

Acupuncture for cancer-related insomnia: systematic review and meta-analysis of randomised controlled trials

BACKGROUND

Acupuncture has been demonstrated to be a safe and effective treatment for insomnia in patients without cancer. A lack of evidence, however, supports its application in the treatment of cancer-related insomnia (CRI).

OBJECTIVE

To conduct a systematic review and meta-analysis to assess the efficacy as well as safety of acupuncture for alleviating insomnia in patients with cancer.

METHODS

A systematic search was conducted using four electronic databases (PubMed, EMBASE, Scopus and the Cochrane Library) to select publications published in peer-reviewed journals written in English. The OR was calculated, along with their 95% CIs. We assessed heterogeneity using Cochrane Q, I2 statistics and the appropriate p value. The analysis used RevMan V.5.3.

FINDINGS

The present meta-analysis comprised 561 individuals from 10 randomised controlled trials (RCTs) across age cohorts. Acupuncture intervention improves Pittsburgh Sleep Quality Index (PSQI) scores and CRI more than control, with a pooled OR of 1.66 (95% CI 1.12 to 2.46), OR of 5.90 (95% CI 2.64 to 13.23) for electroacupuncture, OR of 2.30 (95% CI 1.48 to 3.58) for auricular-acupuncture and 2.72. Acupuncture improved the Insomnia Severity Index (ISI) and CRI more than control approaches, with ORs of 1.31 (95% CI 0.69 to 2.48), 5.29 (95% CI 2.18 to 12.84), 3.17 (95% CI 1.35 to 7.44) and 1.64 (95% CI 1.00 to 2.68).

CONCLUSION

The change in PSQI and ISI scores showed that acupuncture moderately improved insomnia in patients with cancer. Acupuncture is safe and effective, enabling subsequent clinical treatments.

Efficacy and safety of non-pharmacological interventions for cancer-related insomnia: a study protocol for a systematic review and network meta-analysis

INTRODUCTION

Cancer-related insomnia (CRI), a significant concurrent symptom of cancer, profoundly impacts patients. Non-pharmacological interventions include cognitive behavioural therapy, mindfulness-based stress reduction programmes, bright light, acupuncture, exercise and music therapies and tai chi. These approaches, unlike pharmacological treatments, exhibit minimal adverse effects, without drug-drug interactions. They are a promising treatment strategy for CRI patients. However, a comprehensive comparative study evaluating the efficacy and safety of all non-pharmacological interventions for CRI is lacking. Accordingly, we aim to conduct a relatively comprehensive systematic review and network meta-analysis.

METHODS AND ANALYSIS

We will conduct an extensive search across various databases, including Pubmed, Web of Science, Cochrane Library, Embase, Google Scholar, China National Knowledge Infrastructure (CNKI), China Biomedical Literature Database (CBM), Wanfang and Vip databases (VIP). The search will focus on non-pharmacological therapeutic interventions related to CRI in randomised controlled trials published from the inception of these databases until 15 May 2024. The primary outcomes of this study will encompass the Pittsburgh Sleep Quality Index (PSQI) and the Insomnia Severity Index (ISI), while the secondary outcomes will evaluate sleep parameters, fatigue levels, anxiety-depressive mood, quality of life and any potential adverse effects. Paired meta-analyses and network meta-analyses will be conducted utilising ADDIS V.1.16.8, Stata V.14.2 and V.R4.1.2. Bias risk will be independently assessed using the Cochrane Risk of Bias tool (ROB V.2.0), and the evidence quality will be evaluated according to Grading of Recommendations Assessment, Development, and Evaluation (GRADE) standards.

ETHICS AND DISSEMINATION

There are no ethical issues as this study did not conduct any experiments, surveys, or human trials. We will ensure that the findings are shared through pertinent channels.

Efficacy and safety of acupuncture for the treatment of insomnia in breast cancer patients: A systematic review and meta-analysis

BACKGROUND

Breast cancer-related insomnia is one of the most common symptoms in patients with breast cancer, and acupuncture has been increasingly used in the treatment. However, there has been no meta-analysis that specifically explores the efficacy and safety of acupuncture in treating insomnia related to breast cancer.

OBJECTIVE

The aim of this review was to systematically analyze the existing literature through a meta-analysis to evaluate the effectiveness and safety of acupuncture for breast cancer-related insomnia.

METHODS

Six medical databases were comprehensively searched for previous randomized controlled trials (RCTs) up to April 2024. The Pittsburgh Sleep Quality Index (PSQI) score was the primary outcome. The secondary outcomes include the Insomnia Severity Index (ISI), Sleep Onset Latency (SOL), Wake After Sleep Onset (WASO), Total Sleep Time (TST), and Sleep Efficiency (SE), and the later four outcomes were measured by Actiwatch and sleep diary, respectively.

RESULTS

A total of seven articles with 434 participants were included. The meta-analysis revealed that acupuncture produced a significant improvement in the total PSQI score (MD 95 %CI = -2.16[-2.88, - 1.45], P < 0.001), but had no statistical significance on ISI scores compared with controls (MD 95 %CI = -1.53[-3.97, 0.91], P = 0.22). From the Actiwatch, there was no substantial disparity observed in the enhancement of Sleep Onset Latency (SOL) (MD 95 %CI = -6.40[-13.19, 0.39], P = 0.06), Wake After Sleep Onset (WASO) (MD 95 %CI = -1.45[-7.09, 4.20], P = 0.62), or Total Sleep Time (TST) (MD 95 %CI = 3.54 [-4.71, 11.79], P = 0.40) between the experimental group and the control group. However, a significant distinction was observed in Sleep Efficiency (SE) improvement (MD 95 %CI = 2.43 [0.14, 4.72], P = 0.04). From the sleep diary, there was a significant difference in the amelioration of SOL (MD 95 %CI = -9.15[-16.48, - 1.81], P = 0.01), TST (MD 95 %CI = 29.92 [16.74, 43.10], P < 0.001), and SE (MD 95 %CI = 4.57 [1.92, 7.23], P = 0.0007) between the experimental group and the control group. However, no significant divergence was observed in the improvement of WASO (MD 95 %CI = 4.53[-4.81, 13.87], P = 0.34). All reported acupuncture-related adverse events were mild in severity.

CONCLUSIONS

Acupuncture can partially alleviate insomnia symptoms in breast cancer patients. Moreover, acupuncture is safe and may serve as a dependable alternative therapy in clinical settings. Owing to the limited number of studies included, potential biases of heterogeneous interventions, and methodological weaknesses of long-term follow-up, more high-quality RCTs with large sample sizes should be conducted to evaluate acupuncture treatment.

Efficacy of acupuncture therapy on cancer-related insomnia: a systematic review and network meta-analysis

Objectives

Cancer-related insomnia (CRI) takes a toll on many cancer survivors, causing distressing symptoms and deteriorating the quality of life. Acupuncture therapy has been used for CRI already. However, it is still uncertain which acupuncture regime is best for CRI. The primary objective of this review is to conduct a comparative evaluation and ranking of the effectiveness of different acupuncture therapies for CRI.

Methods

Randomized controlled trials (RCTs) that were published up to July 31, 2023, from 8 databases (PubMed, Embase, Cochrane library, Web of Science, China National Knowledge Infrastructure, Wanfang Database, VIP Database, and China Biology Medicine disc) were integrated in this study. Trials that met the inclusion criteria were evaluated the risk of bias. Pittsburgh sleep quality index (PSQI) was used to assess the efficacy of different acupuncture therapies as the primary outcome. Then, STATA 15, R, and OpenBUGS were applied to perform the network meta-analysis. PRISMA statements were followed in this network meta-analysis.

Results

A total of 37 studies were included in this review, involving 16 interventions with 3,246 CRI participants. Auriculotherapy + moxibustion [surface under the cumulative ranking curve (SUCRA) 98.98%] and auriculotherapy (SUCRA 77.47%) came out top of the ranking, which were more effective than control, medicine, usual care and sham acupuncture.

Conclusion

Auriculotherapy + moxibustion and auriculotherapy + acupuncture emerged as the top two acupuncture regimes for CRI and future studies should pay more attention to CRI.
