Cryotherapy for prevention of chemotherapy induced peripheral neuropathy in breast cancer

Peripheral neuropathy is a well-described complication of chemotherapy. There are no known treatments to reverse peripheral neuropathy. Chemotherapy-induced peripheral neuropathy is a dose-limiting toxicity in cancer treatment and is debilitating. Cryotherapy, or the use of cold garments/ice bags applied to extremities during chemotherapy, is a method to prevent or minimize treatment related neuropathy. There is no standard method of providing cryotherapy currently. A review of the literature was performed revealing that a variety of cryotherapy methods exist. While small studies suggest potential preventive effect of some forms of cryotherapy, consistent results from well-designed randomized studies are lacking. A small benefit from the use of cryotherapy to prevent peripheral neuropathy might exist, but conflicting studies exist. In light of the low cost to implement ice bags during chemotherapy and the low risk of toxicity, the use of ice bags may be reasonable during taxane chemotherapy for the treatment of breast cancer.
