Incidence of chemotherapy-induced peripheral neuropathy within 12 weeks of starting neurotoxic chemotherapy for multiple myeloma or lymphoma: a prospective, single-center, observational study

Role of alpha-lipoic acid in counteracting paclitaxel- and doxorubicin-induced toxicities: a randomized controlled trial in breast cancer patients

BACKGROUND AND OBJECTIVE

Paclitaxel and doxorubicin are associated with neurotoxicity and cardiotoxicity respectively. This study aimed at investigating the role of alpha-lipoic acid (ALA) in counteracting paclitaxel-induced neuropathy and doxorubicin-associated cardiotoxicity in women with breast cancer.

PATIENTS AND METHODS

This randomized double-blind placebo-controlled prospective study included 64 patients with breast cancer who were randomized into control group (n = 32) which received 4 cycles of doxorubicin plus cyclophosphamide (every 21 days) followed by weekly doses of paclitaxel for 12 weeks plus placebo tablets once daily and ALA group (n = 32) which received the same chemotherapeutic regimen plus ALA 600 once daily for 6 months. Patients were assessed by National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE version 4.0) for grading of neuropathy and by 12-item neurotoxicity questionnaire (Ntx-12). The assessment included also echocardiography and evaluation of serum levels of brain natriuretic peptide (BNP), tumor necrosis factor-alpha (TNF-α), malondialdehyde (MDA), and neurotensin (NT). Data were analyzed by paired and unpaired t-test, Mann-Whitney U test, and chi-square test.

RESULTS

As compared to placebo, ALA provoked significant improvement in NCI-CTCAE neuropathy grading and Ntx-12 score after the end of 9th and 12th weeks of paclitaxel intake (p = 0.039, p = 0.039, p = 0.03, p = 0.004, respectively). At the end of the chemotherapy cycles, ALA resulted in significant decline in serum levels of BNP, TNF-α, MDA, and neurotensin (p < 0.05) as compared to baseline data and placebo.

CONCLUSION

Alpha-lipoic acid may represent a promising adjuvant therapy to attenuate paclitaxel-associated neuropathy and doxorubicin-induced cardiotoxicity in women with breast cancer.

Efficacy of Siriraj, in-house-developed, frozen gloves for cold therapy reduction of chemotherapy-induced peripheral neuropathy in gynecological cancer patients: randomized controlled trial

OBJECTIVES

The primary objective of this study was to investigate the efficacy of cold therapy in reducing paclitaxel-based, chemotherapy-induced, peripheral neuropathy (CIPN). The secondary objective was to establish the incidence of CIPN arising from paclitaxel administration.

MATERIALS AND METHODS

The study enrolled gynecological cancer patients who were aged over 18 years and receiving chemotherapy which included paclitaxel (175 mg/m² every 3 weeks). The patients were allocated to control and cold-therapy groups by computer randomization. During paclitaxel administration, frozen gloves developed in-house by Siriraj Hospital were worn-with a cold pack inside-on both hands and both feet by the cold-therapy patients. The CIPN incidence was evaluated by FACT/GOG-Ntx (version 4) at each chemotherapy cycle and at the 1-month follow-up after treatment completion.

RESULTS

There were 79 patients (control arm, 40; study arm, 39). The CIPN incidences in the control and cold-therapy groups were 100% and 48.7%, respectively. CIPN was significantly decreased in the intervention group between the first cycle and the 1 month follow-up after chemotherapy cessation (P value < 0.001). Four patients discontinued the cold therapy due to pain, but there were no serious adverse effects due to the therapy.

CONCLUSION

The Siriraj Hospital, in-house-developed, frozen gloves can reduce CIPN effectively as part of cold therapy for paclitaxel-based chemotherapy. The benefits of using the gloves are apparent from the first chemotherapy cycle to the 1-month, post-treatment follow-up assessment.

Self-Reported Severity, Characteristics, and Functional Limitations of Chemotherapy-Induced Peripheral Neuropathy

BACKGROUND

The early identification of chemotherapy-induced peripheral neuropathy (CIPN) (e.g., numbness or tingling in the fingers or toes) is important due to its frequency and the few effective treatment options available. The identification of common patient-reported CIPN characteristics and associated functional limitations may help to facilitate patient-clinician discussions of CIPN in practice.

AIMS

To quantify the severity, duration, location, characteristics, and associated functional limitations of chemotherapy-induced peripheral neuropathy (CIPN) in patients receiving neurotoxic chemotherapy.

DESIGN

Exploratory secondary analysis of a prospective, two-phase study SETTING: Breast, gastrointestinal, and multiple myeloma clinics at Dana-Farber Cancer Institute.

PARTICIPANTS

142 individuals who planned to receive at least three more cycles of neurotoxic chemotherapy after consent.

METHODS

Participants self-reported CIPN using standardized measures (i.e., PRO-CTCAE™ Numbness and Tingling Items or 0-10 numerical rating scale of worst CIPN pain intensity) and/or study team generated follow up questions about CIPN location, duration, characteristics, and functional limitations prior to three consecutive clinic visits (T1, T2, T3). Participants' responses to the CIPN self-report questionnaires were described by chemotherapy type and age.

RESULTS

Over approximately 36.5 days (T1-T3), the percentage of participants reporting at least mild CIPN increased from 59.3% to 71%. At T3, patients with non-painful (n = 98) or painful neuropathy (n = 34) frequently reported symptoms in the fingers (non-painful = 83.5%, painful = 76.5%) or toes (non-painful = 49.5%, painful = 41.2%) and characterized symptoms as numbness (non-painful = 54.1%, painful = 50%) or tingling (non-painful = 68.4%, painful = 82.4%). Self-reported CIPN functional limitations (n = 55) included difficulties with buttoning a shirt (38.2%) or walking (25.5%). Paclitaxel-related CIPN (n = 33) was frequently characterized as "continuous" (30.3%), whereas oxaliplatin-related CIPN (n = 51) was frequently characterized as "intermittent" (41.2%). Young adults (15-39 years old, n = 15) frequently reported moderate-severe non-painful CIPN (46.7%), painful CIPN (40%), and CIPN interference (33.3%).

CONCLUSIONS

Consistent with qualitative research, participants frequently described CIPN as numbness and/or tingling in the fingers and/or toes.

Impact of Chemotherapy-Induced Peripheral Neuropathy on Quality of Life in Patients with Advanced Lung Cancer Receiving Platinum-Based Chemotherapy

Chemotherapy-induced peripheral neuropathy (CIPN) is a common adverse effect of neurotoxic anticancer drugs that may affect quality of life (QoL). Purpose: The purposes of this study were to: assess the levels of CIPN, anxiety, depression, CIPN–related QoL, and general QoL; and identify the factors related to CIPN–related QoL and general QoL in patients with advanced lung cancer (LC) receiving platinum-based chemotherapy. This cross-sectional study examined patients with advanced LC who received platinum-based chemotherapy from the thoracic oncology inpatient wards of a medical center in northern Taiwan. Structured questionnaires were used to measure patients’ CIPN (European Organization for Research and Treatment of Cancer quality of life questionnaire–chemotherapy–induced peripheral neuropathy 20), anxiety (Hospital Anxiety and Depression Scale Depression Scale [HADS]), depression (HADS), CIPN-related QoL (Functional Assessment of Cancer Therapy /Gynecologic Oncology Group-Neurotoxicity subscale [FACT/GOG–Ntx]), and general QoL (Functional Assessment of Cancer Therapy–General Input [FACT-G]). Of 93 patients with advanced LC, 53.8% reported CIPN–sensory impairment and 47.3% reported CIPN–motor impairment. The most common CIPN symptoms were difficulty getting or maintaining an erection (only for men > 65 years) and difficulty in climbing stairs or getting up out of a chair. Poor CIPN–related QoL (FACT/GOG–Ntx) was associated with more CIPN–sensory and more CIPN–motor impairment. Poor general QoL (FACT-G) was associated with a higher level of depression, a higher level of anxiety, and receipt of more chemotherapy cycles. More than half of LC patients report impairment related to CIPN, calling for holistic treatment to improve QoL.
