Safety of compression therapy using newly developed gloves for oxaliplatin induced neuropathy prevention.

Abstract

501 Background: Oxaliplatin (l-OHP) is a key drug commonly used in primary and metastatic colorectal cancer treatment. However, l-OHP is associated with non-hematological adverse effects, including peripheral neuropathy (PN). About 90% of patients who received l-OHP experience PN after single dose of l-OHP and PN is likely to be negatively associated with quality of life. There is no established effective prophylactic management for chemotherapy induced PN according to the 2014 American Society of Clinical Oncology (ASCO) guideline. Recently, compression of hands during injection of drugs has been reported to be effective for chemotherapy induced PN. We developed new gloves for compression therapy which are reusable and low cost. We prospectively analyzed the safety of the gloves. Methods: Patients who received l-OHP were eligible for this phase Ⅰ study. Wrist and hand size were measured and appropriate size of gloves were selected. The pressure of hands is estimated as 20-33 hPa. Patients start to wear the gloves on both hands, from 30 min before the injection of l-OHP until 30 min after the injection. Peripheral neuropathy was evaluated at each treatment cycle using common terminology criteria for adverse events (CTCAE) version 4.0. Results: Between October 2017 and August 2018, fourteen patients (median age 66 years [range 39– 79years], 7 male and 7 female) were enrolled and were evaluated. No patients withdrew from this study. No safety concerns were identified for any safety variables assessed during the trial. CTCAE grade 2 or higher sensory PN was observed in four (28.6%) patients. The average time until grade 1 or more neuropathy appeared was 27.8 days and average dose of l-OHP was 225mg. Conclusions: Compression therapy by the new gloves had no safety concerns, demonstrating a profile favorable for further development for prevention of oxaliplatin induced PN.
