COMPACT was an open-label, multicenter, noninterventional study (NCT00857012) conducted in Germany. This study provided the first prospective data from routine clinical practice on the relationship between arthralgia and patient compliance during the first year of adjuvant anastrozole therapy in postmenopausal women with hormone receptor-positive early breast cancer. Arthralgia may contribute to noncompliance and clinical outcomes in these patients.This prospective study evaluated the relationship between arthralgia and compliance during the first year of adjuvant anastrozole therapy in postmenopausal women with hormone receptor-positive early breast cancer. COMPliance and Arthralgia in Clinical Therapy (COMPACT) was an open-label, multicenter, noninterventional study conducted in Germany. Patients had started adjuvant anastrozole 3-6 months before the study start. The primary end points were arthralgia, compliance, and the relationship between compliance and arthralgia, assessed at specific time points. Overall, 1916 patients received upfront anastrozole. Mean arthralgia scores were increased from baseline at each visit up to 9 months. Compliance with anastrozole therapy gradually decreased over time from baseline to 9 months (P < 0.001). At 9 months, investigators estimated that > 95% of patients were compliant versus patient reports of < 70%. There was a significant association between arthralgia mean scores and noncompliance at 6 months (P < 0.0001), 9 months (P < 0.0001), and overall (P < 0.0001). Over time, new events or impairment of existing arthralgias were reported in 14% (3 months), 11% (6 months), and 9% (9 months) of patients. Arthralgia is important in the clinical management of women with early breast cancer and may contribute to noncompliance and clinical outcomes.
