Patients with cancer who experience chemotherapy-induced peripheral neuropathy (CIPN) may experience improvement with exercise, according to a study published in Supportive Care in Cancer.
CIPN is a commonly occurring morbidity associated with cancer therapy; approximately 50% of patients who receive taxane, platinum, or vinca-alkaloid–based chemotherapy experience peripheral neuropathy, but effective therapeutic options are limited.
For this study, researchers evaluated the outcomes of 456 patients with cancer treated with CIPN-inducing chemotherapy regimens. Patients were randomly assigned to receive either chemotherapy or chemotherapy plus the Exercise for Cancer Patients (EXCAP) program, in which patients undergo moderate-intensity walking and resistance exercises for 6 weeks. All patients reported CIPN symptoms preintervention and postintervention.
Of the 456 patients enrolled, 355 completed both intervention assessments and were eligible for evaluation. Reasons for study drop-out included feeling overwhelmed, experienced some medical issue, or no reasons were given. Exercise-arm assignment, limited education, older age, and greater baseline fatigue were factors found to be significantly associated with study incompletion upon multivariate analysis.
After 6 weeks of chemotherapy, CIPN severity unexpectedly worsened compared with baseline reports, but to a lesser extent among patients assigned to the exercise arm. Analysis showed that the increases in CIPN symptoms of hot/coldness in hands/feet and numbness/tingling were lower by .46 units (P =.045) and 0.42 units (P =.076), respectively, among patients in the exercise arm compared with the control arm.
Patients who were older (P =.086), male (P =.028), and had breast cancer (P =.076) experienced greatest reduction of symptoms with exercise.
The authors concluded that exercise “is a promising tool that clinicians should consider prescribing for patients receiving taxane-based, platinum-based, and vinca alkaloid-based drugs, especially for geriatric patients.
