Cryocompression to Reduce Peripheral Neuropathy in Gynecologic Cancer: A Randomized Controlled Trial.

Objective: To investigate the efficacy of cryocompression therapy to prevent chemotherapy-induced peripheral neuropathy.
Methods: This single-institution, randomized, self-controlled trial of cryocompression enrolled gynecologic cancer patients planned for five to six cycles neurotoxic chemotherapy. Exclusion criteria were prior neurotoxic chemotherapy or baseline peripheral neuropathy. Participants were randomized to cryocompression on dominant versus non-dominant hand and foot (treatment), with no intervention on the opposite side (control). Compression socks and gloves and ice bags were applied 15 minutes before, during, and 15 minutes after infusion. Primary outcome measures included the PNQ (Patient Neurotoxicity Questionnaire) and the Semmes-Weinstein monofilament test; secondary outcomes included the FACT/GOG-NTX (Functional Assessment of Cancer Therapy/Gynecologic Oncology Group - Neurotoxicity) and patient acceptability and tolerability. Sixty patients completing the study were necessary to detect a 70% reduction in the odds of PNQ grade C or higher peripheral sensory neuropathy with 80% power.
Results: Ninety-one patients were enrolled from January 2021 to October 2022; 69 were eligible for final analysis. Of the 91 patients, 64.8% were White, 30.8% were Black, and 1.1% were Hispanic or Latina. With successive cycles, more patients had sensory PNQ grade C or higher neuropathy on the control side compared with the cryocompression side. Cryocompression decreased the odds of sensory neuropathy (PNQ grade C or higher) by 46% at final visit (odds ratio 0.54, 95% CI 0.31-0.94; P =.03). There was no difference in tactile sensitivity based on the monofilament test between sides at the final visit. At the final visit, average FACT/GOG-NTX-11 (Functional Assessment of Cancer Therapy/Gynecologic Oncology Group - Neurotoxicity 11 Item Version) scores were significantly lower on the cryocompression than the control side (estimate -0.97, 95% CI -1.89 to -0.06; P =.04), as were FACT/GOG-NTX-4 (Functional Assessment of Cancer Therapy/Gynecologic Oncology Group - Neurotoxicity 4 Item Version) scores (estimate -0.35, 95% CI -0.64 to -0.05; P =.02). More than 85% of patients assessed the intervention as acceptable and tolerable.
Conclusions: Cryocompression therapy reduces subjective chemotherapy-induced peripheral sensory neuropathy in patients who are receiving paclitaxel or cisplatin for gynecologic cancer.
