Chemotherapy dose reduction due to chemotherapy induced peripheral neuropathy in breast cancer patients receiving chemotherapy in the neoadjuvant or adjuvant settings: a single-center experience

Abstract: Purpose: Taxanes are a cornerstone treatment in early and advanced stage breast cancer and in other common solid tumor malignancies; however, the development of chemotherapy induced peripheral neuropathy (CIPN) often necessitates dose-reduction, which may hamper the effectiveness of the drug and compromise survival outcomes especially when used in the adjuvant setting. Limited literature is available on the prevalence and severity of dose reduction due to CIPN. We sought to determine the frequency and severity of CIPN-induced dose reduction in early stage breast cancer patients who received taxane-based chemotherapy in the neoadjuvant or adjuvant settings. Methods: We conducted a retrospective single-institution breast cancer clinic chart review of 123 newly diagnosed breast cancer patients and treated with taxane-based neoadjuvant/adjuvant chemotherapy at the University of Maryland Greenebaum Cancer Center between January 2008 and December 2011. Results: Forty-nine of 123 (40%; 95% CI: 31-49%) patients required dose reduction. Twenty-one (17%; 95% CI: 11-25%) of these patients were dose-reduced specifically due to CIPN that developed during treatment. The median relative dose intensity (received dose/planned dose) for the 21 CIPN-induced dose reduction patients was 73.4% (range, 68.0-94.0%). Patients with diabetes appeared to have a higher risk of taxane-induced dose reduction (p-value=0.01). African-American patients and those treated with paclitaxel (rather than docetaxel) experienced a higher-risk of CIPN-induced dose reduction (p-values are <0.001 and 0.001, respectively). Conclusions: The incidence of CIPN-associated dose reduction in our patient population was 17%. African-American patients, diabetics and subjects treated with paclitaxel had a higher risk for CIPN-associated dose reduction in our study.

A Pilot Study of Acupuncture in Treating Bortezomib-Induced Peripheral Neuropathy in Patients With Multiple Myeloma

Abstract: Background. Peripheral neuropathy is the dose limiting toxicity of bortezomib in patients with multiple myeloma (MM). Objectives. To examine the safety, feasibility and efficacy of acupuncture in reducing bortezomib-induced peripheral neuropathy (BIPN) symptoms. Methods. Patients with MM experiencing persistent BIPN ≥grade 2 despite adequate medical intervention and discontinuation of bortezomib received 10 acupuncture treatments for 10 weeks (2×/week for 2 weeks, 1×/week for 4 weeks, and then biweekly for 4 weeks). Responses were assessed by the Clinical Total Neuropathy Score (TNSc), Functional Assessment of Cancer Therapy/Gynecologic Oncology Group–Neurotoxicity (FACT/GOG-Ntx) questionnaire, and the Neuropathy Pain Scale (NPS). Repeated-measures analysis of variance was used to test for monotonic decline in scores on each of the measures. Serial serum levels of proinflammatory and neurotrophic cytokines were obtained at baseline and weeks 1, 2, 4, 8, and 14. Results. Twenty-seven patients with MM were ...

Patient‐reported outcomes in women with breast cancer enrolled in a dual‐center, double‐blind, randomized controlled trial assessing the effect of acupuncture in reducing aromatase inhibitor‐induced musculoskeletal symptoms

Abstract: Background Aromatase Inhibitors (AIs) have been associated with decrements in patient-reported outcomes (PROs).
