Aromatase inhibitors (AIs) are used as a treatment in breast cancer; however, a side effect of their use is often the development of aromatase inhibitor induced arthralgia (AIA), which manifests as pain in the joints, muscle weakness and reduced grip strength. Subsequently, many individuals stop taking AIs, resulting in poorer disease prognosis. Tart cherries (TC) have been shown in studies to help relieve joint pain and pain associated with exercise and so this RCT aimed to determine the effect of TC consumption on 60 breast cancer patients with AIA. The results showed that after 6-weeks individuals given TC had less pain, with some individuals reporting no pain at all. It was concluded that TC is a reliable and safe option for the management of AIA in breast cancer patients. This study could be used by healthcare professionals to recommend TC as an adjunct to aromatase inhibitor therapy in individuals with breast cancer who are experiencing pain.
BACKGROUND
Aromatase Inhibitor induced Arthralgia (AIA) can cause noncompliance leading to decreased breast-cancer survival. Effective interventions for AIA are limited. Tart cherry (TC) showed beneficial effect on musculoskeletal pain. 48 patients (Pts) randomized to TC versus placebo over 6 weeks, TC (23pts) had 34.7% mean pain decrease versus 1.4% in Placebo (25pts). TC can improve AIA in nonmetastatic breast-cancer patients.
METHODS
Randomized, placebo-controlled, double-blind trial. Eligible patients with NMHPBC on AI for at least 4 weeks were randomized to TC concentrate [50 tart cherries] vs. placebo (P) [syrup] in 1:1 model. Patients instructed to consume 1 Oz of concentrate in 8 Oz water daily for 6 weeks, and document their pain intensity at baseline, weekly and at study completion in a diary using Visual Analog Scale (VAS), with 0 mm indicating no pain, and 100 mm indicating highest pain.
RESULTS
Sixty patients were enrolled. Two patients did not complete the study due to diarrhea, and 10 patients were noncompliant. Forty-eight patients were included in the final analysis. TC group (23 pts) had 34.7% mean decrease in pain compared to 1.4% in P group (25 pts). This difference was statistically significant (Mann-Whitney U Test, P = .034).
CONCLUSIONS
Tart cherry can significantly improve AIA in nonmetastatic breast cancer patient.
