Chemotherapy-induced peripheral neuropathy (CIPN) in breast cancer survivors: a comparison of patient-reported outcomes and quantitative sensory testing

AbstractPurposeCIPN is a common, debilitating, and dose-limiting side effect of chemotherapy. Here, we describe characteristics of patients with CIPN using both patient-reported outcomes (PRO) and quantitative sensory testing (QST).MethodsBreast cancer survivors with persistent moderate to severe CIPN defined by a rating of 4 or greater on a 0 –10 Numeric Rating Scale (NRS) from two ongoing clinical trials were included. PROs included the Neuropathic Pain Scale (NPS) and Functional Assessment of Cancer Therapy-Gynecologic Oncology Group/Neurotoxicity (FACT/GOG-Ntx). QST included tactile and vibration detection threshold measurements. Da ta were analyzed using descriptive statistics and Spearman correlation coefficients.Results49 female patients with a mean age of 61  years were assessed; 63% were Caucasian. Mean NRS scores were 4.2, 5.7, and 4.3 on 0–10 scale for pain, numbness, and tingling, respectively. Mean NPS score was 41.0 on a 0–100 scale, and the mean FACT/GOG-Ntx score was 25.8 on a 0–44 scale. QST showed mild to moderate impairments in tactile and vibration perception. The FACT/GOG-Ntx subscale for numbness was negatively correlated with tactile and vibration thresholds in both hands and feet (bothp

This study aimed to prospectively explore severity and prevalence of chemotherapy-induced peripheral neuropathy (CIPN) and examine the correlation between clinician-assessed (objective) and patient-reported (subjective) CIPN in breast cancer survivors receiving taxane.MethodsThis was a prospective, longitudinal study. Purposive sampling was adapted to enroll women newly diagnosed with breast cancer and about to receive taxane. The CIPN was assessed after breast cancer diagnosed and before chemotherapy (T1), before cycle 1 to 4 taxane infusion (T2 to T5), and after chemotherapy completion (T6 to T8). Total Neuropathy Score ...

This study was undertaken to investigate the analgesic effects of electrical stimulation on docetaxel-induced neuropathic pain in mice and to identify associated changes in ultrasound vocalizations. Peripheral neuropathy was induced with intraperitoneally injected docetaxel (5 mg/kg) on 3 times every 2 days in male ICR mice. Electrical wrist stimulation was administered and pain behavior signs were evaluated by von Frey filaments and thermal stimulation on the hind paw. Ultrasound vocalizations were measured using ultrasound microphones, after electrical stimulation. After mice developed docetaxel-induced neuropathi...

Conclusion Contactin-1 IgG has a distinct sensory predominant presentation commonly associated with neuropathic pain, with demyelinating changes on electrophysiologic studies. A paraneoplastic cause should be considered. Testing of contactin-1 IgG among cases with similar presentations may guide immunotherapy selection, especially second-line immunotherapy consideration.

ConclusionThis is an initial report demonstrating the potential of rTMS for the treatment of CIPN. We suggest rTMS could be potentially beneficial and effective as a treatment for pain and dysesthesia in patients with CIPN.

This study aimed to compare the efficacy and safety of pregabalin (150  mg daily) and duloxetine (60 mg daily) for managing TIPN in breast cancer patients.MethodsThis randomized, double-blind, Phase II clinical trial was carried out at a chemotherapy center affiliated to Mazandaran University of Medical Sciences. Patients with breast cancer who received paclitaxel or docetaxel and had a grade 1 or more neuropathy (based on the National Cancer Institute Common Terminology Criteria for Adverse Events version (NCI-CTCAE v4.03), and who had score 4 or higher neuropathic pain severity [based on the visual analog scale...

This study aims to evaluate the efficacy and safety of the concurrent use of two complementary and alternative therapies: electroacupuncture (EA) and Chuna manual therapy (CMT), with pregabalin, which is the conventional pharmacotherapy for neuropathic pain. Methods/design: This is an open-label, parallel, assessor-blinded randomized controlled trial, which includes 90 patients with colorectal and breast cancer, who developed CIPN. After a 2-week preparation period, the patients are divided into three groups (pregabalin administration group, pregabalin + EA treatment group, and pregabalin + CMT treatment group), treated...

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 impro...
