Cryotherapy

PURPOSE: This randomized phase II study was conducted to investigate the efficacy of cryotherapy in preventing peripheral neuropathy and dermatological adverse events in breast cancer patients treated with weekly paclitaxel.

METHODS: Patients treated with 12 weekly doses of paclitaxel for breast cancer were randomized (1:1) into a cryotherapy or control group. The primary endpoint was the percentage of patients with a marked decrease in the Functional Assessment of Cancer Therapy-Neurotoxicity (FACT-NTX) score. The secondary endpoints were Patient Neurotoxicity Questionnaire (PNQ), Common Terminology Criteria for Adverse Event (CTCAE) for peripheral neuropathy, and FACT-Taxane score.

RESULTS: Forty-four patients were randomly assigned to the cryotherapy (n = 22) or control groups (n = 22). The percentage of patients with a marked decrease in FACT-NTX scores was significantly lower in the cryotherapy group than in the control group (41 vs. 73%, p = 0.03). The incidence of CTCAE grade ≥ 2 sensory (p = 0.001) and motor peripheral neuropathy (p = 0.01), and PNQ grade D or higher for sensory peripheral neuropathy (p = 0.02), and decrease in the FACT-Taxane score (p = 0.02) were also significantly lower in the cryotherapy group than in the control group. There were no serious side effects associated with cryotherapy.

CONCLUSION: Cryotherapy is an effective approach for prevention of peripheral neuropathy and dermatological adverse events in breast cancer patients treated with weekly paclitaxel.
