UNLABELLED: Chemotherapy-induced peripheral neuropathy (CIPN) can cause loss of independence and poor quality of life (QoL) due to severe disabilities, but in spite of its importance there is still a lack of data for the management of CIPN. Acupuncture has showed promising results and may be a cost-effective option for the treatment.
OBJECTIVES: To evaluate the effect of acupuncture treatment on neurological symptoms of CIPN and QoL of oncological patients.
METHODS: We performed a clinical, single-centre, randomised and controlled pilot study that involved 33 adult patients with cancer and CIPN randomised into two groups (control and acupuncture treated with 10 sessions, two times per week). Both groups were subjected to a complete physical examination and clinical assessment with National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) Scale V.2.0, FIM Scale, European Organisation for the Research and Treatment of Cancer Quality of Life Questionnaire Core (EORTC QLQ-C30) Scale and Visual Analogue Scale for pain before and 5 weeks after treatment.
RESULTS: There were no adverse events, and we found statistical differences in groups in physical (p=0.03) and function (p=0.04) domains of EORTC QLQ-C30 when comparing control and acupuncture groups. About NCI CTCAE Scale and neuropathy sensory symptoms, we found better results in acupuncture group, comparing pretreatment and post-treatment analyses (p=0.01). In control group, we have no differences after 5 weeks (p=0.11).
CONCLUSION: Although these results suggest an interesting effect of acupuncture on this patient population, the clinical significance has remained unclear. Given the tendency towards benefit and the lack of adverse effects, the authors recommend a follow-up acupuncture trial using higher follow-up time and better sample size.
TRIAL REGISTRATION NUMBER: NCT02309164.
<b>CONTEXT: </b>Preliminary trials report that Scrambler Therapy, a form of electroanalgesia, may improve discomfort from chemotherapy-induced peripheral neuropathy (CIPN).<b>OBJECTIVE: </b>The objective of this phase II, randomized controlled trial was to evaluate the efficacy of Scrambler therapy vs. transcutaneous electrical nerve stimulation (TENS) in treating CIPN.<b>METHODS: </b>Fifty patients were accrued for the first half of this two-part, crossover trial consisting of a 2-week treatment period with either Scrambler or TENS, followed by an 8-week observation period, and then crossover treatment. Twenty-two patients proceeded to the crossover phase. The primary means of assessment was patient-reported outcomes, including symptom severity scales and Global Impression of Change questionnaires. Symptoms were assessed daily during the treatment period and weekly during an 8-week observation period.<b>RESULTS: </b>A 50% or greater reduction in primary symptom (pain or tingling) score on the last day of treatment was achieved by 6 of 10 Scrambler-treated patients (60%) and 3 of 12 TENS-treated patients (25%) after crossover (P = 0.11). By day 4 of treatment, the two arms diverged with respect to mean change in primary symptom score; this effect was largely carried through to the end of the two-week treatment period. Similarly, Scrambler therapy appeared better than TENS when assessed by Global Impression of Change for neuropathy, pain, and overall quality of life.<b>CONCLUSIONS: </b>Similar findings from the initial randomization and crossover phases of this study support further evaluation of the efficacy of Scrambler therapy in alleviating CIPN symptoms. Evaluation in a larger, randomized controlled trial with standardized treatment is warranted.
BACKGROUND: Chemotherapy-induced peripheral neuropathy (CIPN) is a common, debilitating side effect that worsens quality of life and increases the risk of falls in cancer survivors. Evidence of yoga's safety and efficacy in treating CIPN is lacking.
METHODS: In a randomized controlled study, we assigned breast and gynecological cancer survivors with persistent moderate-to-severe CIPN pain, numbness, or tingling with a score of 4 or greater (0-10 numeric rating scale [NRS]) for at least 3 months after chemotherapy to 8 weeks of usual care or yoga focused on breathwork and musculoskeletal conditioning. Primary endpoint was treatment arm differences for NRS, and secondary endpoints were Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity subscale (FACT/GOG-Ntx), and Functional Reach Test after week 8. We tested treatment arm differences for each outcome measure using linear mixed models with treatment-by-time interactions. All statistical tests were two-sided.
RESULTS: We randomly assigned 41 participants into yoga (n = 21) or usual care (n = 20). At week 8, mean NRS pain decreased by 1.95 points (95% confidence interval [CI] = -3.20 to -0.70) in yoga vs 0.65 (95% CI = -1.81 to 0.51) in usual care (P = .14). FACT/GOG-Ntx improved by 4.25 (95% CI = 2.29 to 6.20) in yoga vs 1.36 (95% CI = -0.47 to 3.19) in usual care (P = .035). Functional reach, an objective functional measure predicting the risk of falls, improved by 7.14 cm (95% CI = 3.68 to 10.59) in yoga and decreased by 1.65 cm (95% CI = -5.00 to 1.72) in usual care (P = .001). Four grade 1 adverse events were observed in the yoga arm.
CONCLUSION: Among breast and gynecological cancer survivors with moderate-to-severe CIPN, yoga was safe and showed promising efficacy in improving CIPN symptoms.
This randomized clinical trial investigates the effect of acupuncture vs a sham procedure or usual care for chemotherapy-induced peripheral neuropathy symptoms.
BACKGROUND: Chemotherapy‐induced peripheral neuropathy (CIPN) is one of the most debilitating long‐term side effects in breast cancer survivors. We conducted a randomized controlled pilot trial to assess the feasibility, safety, and effects of an acupuncture intervention on CIPN in this population. Patients and METHODS: Women with stage I–III breast cancer with grade 1 or higher CIPN after taxane‐containing adjuvant chemotherapy were randomized 1:1 to an immediate acupuncture (IA) arm or to a waitlist control group (CG). Participants in the IA arm received 18 sessions of acupuncture over 8 weeks, then received no additional acupuncture. Patients in the CG arm received usual care over 8 weeks, followed by nine sessions of acupuncture over 8 weeks. Measures including Patient Neurotoxicity Questionnaire (PNQ), Functional Assessment of Cancer Therapy—Neurotoxicity subscale (FACT‐NTX), and Brief Pain Inventory—short form (BPI‐SF) were collected at baseline and at 4, 8, and 16 weeks after enrollment. RESULTS: Forty women (median age, 54) were enrolled (20 to IA and 20 to CG), with median time between completion of chemotherapy and enrollment of 14 months (range 1–92). At 8 weeks, participants in the IA arm experienced significant improvements in PNQ sensory score (−1.0 ± 0.9 vs. −0.3 ± 0.6; p =.01), FACT‐NTX summary score (8.7 ± 8.9 vs. 1.2 ± 5.4; p =.002), and BPI‐SF pain severity score (−1.1 ± 1.7 vs. 0.3 ± 1.5; p =.03), compared with those in the CG arm. No serious side effects were observed. CONCLUSION: Women with CIPN after adjuvant taxane therapy for breast cancer experienced significant improvements in neuropathic symptoms from an 8‐week acupuncture treatment regimen. Additional larger studies are needed to confirm these findings. Implications for Practice: Chemotherapy‐induced peripheral neuropathy (CIPN) is a toxicity that often persists for months to years after the completion of adjuvant chemotherapy for early breast cancer. In a randomized pilot trial of 40 breast cancer survivors with CIPN, an 8‐week acupuncture intervention (vs. usual care) led to a statistically and clinically significant improvement in subjective sensory symptoms including neuropathic pain and paresthesia. Given the lack of effective therapies and established safety profile of acupuncture, clinicians may consider acupuncture as a treatment option for mild to moderate CIPN in practice. Chemotherapy‐induced peripheral neuropathy (CIPN) is a common side effect of chemotherapy. This article describes results of a study that evaluated the feasibility and benefits of acupuncture in breast cancer survivors with CIPN symptoms.
<b>INTRODUCTION: </b>Chemotherapy-induced peripheral neuropathy (CIPN) is a prominent clinical problem, with limited effective therapies. Preliminary non-randomized clinical trial data support that Scrambler Therapy is helpful in this situation.<b>METHODS: </b>Patients were eligible if they had CIPN symptoms for at least 3 months and CIPN-related tingling or pain at least 4/10 in severity during the week prior to registration. They were randomized to receive Scrambler Therapy versus transcutaneous electrical nerve stimulation (TENS) for 2 weeks. Patient-reported outcomes (PROs) were utilized to measure efficacy and toxicity daily for 2 weeks during therapy and then weekly for 8 additional weeks.<b>RESULTS: </b>This study accrued 50 patients, 25 to each of the 2 study arms; 46 patients were evaluable. There were twice as many Scrambler-treated patients who had at least a 50% documented improvement during the 2 treatment weeks, from their baseline pain, tingling, and numbness scores, when compared with the TENS-treated patients (from 36 to 56% compared with 16-28% for each symptom). Global Impression of Change scores for "neuropathy symptoms," pain, and quality of life were similarly improved during the treatment weeks. Patients in the Scrambler group were more likely than those in the TENS group to recommend their treatment to other patients, during both the 2-week treatment period and the 8-week follow-up period (p < 0.0001). Minimal toxicity was observed.<b>CONCLUSIONS: </b>The results from this pilot trial were positive, supporting the conduct of further investigations regarding the use of Scrambler Therapy for treating CIPN.
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 <i>P</i> < 0.001), with a significantly higher reduction in the acupuncture group (<i>P</i> < 0.001 and <i>P</i> = 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 (<i>P</i> = 0.01 and <i>P</i> = 0.001, respectively). The NCS (except for the latency of the sural nerve) in the acupuncture group improved significantly (<i>P</i> < 0.05), while improvement in the vit B1 and gabapentin group was not observed (<i>P</i> > 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. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
Painful chemotherapy-induced peripheral neuropathy (CIPN) is a debilitating and treatment-resistant sequela of many chemotherapeutic medications. Ligands of α2δ subunits of voltage-gated Ca2+ channels, such as pregabalin, have shown efficacy in reducing mechanical sensitivity in animal models of neuropathic pain. In addition, some data suggest that pregabalin may be more efficacious in relieving neuropathic pain in subjects with increased sensitivity to pinprick. We hypothesized that greater mechanical sensitivity, as quantified by decreased mechanical pain threshold at the feet, would be predictive of a greater reduction in average daily pain in response to pregabalin vs placebo. In a prospective, randomized, double-blinded study, 26 patients with painful CIPN from oxaliplatin, docetaxel, or paclitaxel received 28-day treatment with pregabalin (titrated to maximum dose 600 mg per day) and placebo in crossover design. Twenty-three participants were eligible for efficacy analysis. Mechanical pain threshold was not significantly correlated with reduction in average pain (<i>P</i> = 0.97) or worst pain (<i>P</i> = 0.60) in response to pregabalin. There was no significant difference between pregabalin and placebo in reducing average daily pain (22.5% vs 10.7%, <i>P</i> = 0.23) or worst pain (29.2% vs 16.0%, <i>P</i> = 0.13) from baseline. Post hoc analysis of patients with CIPN caused by oxaliplatin (<i>n</i> = 18) demonstrated a larger reduction in worst pain with pregabalin than with placebo (35.4% vs 14.6%, <i>P</i> = 0.04). In summary, baseline mechanical pain threshold tested on dorsal feet did not meaningfully predict the analgesic response to pregabalin in painful CIPN.

<b>BACKGROUND: </b>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.<b>METHODS: </b>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).<b>RESULTS: </b>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).<b>CONCLUSION: </b>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.<b>Trial Registration: </b>German Clinical Trials Register (DRKS) number: DRKS00005419 , prospectively registered on November 19, 2013.
