Abstract

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.
