OBJECTIVE
To assess the effectiveness and safety of a product containing diosmin, coumarin, and arbutin (Linfadren®) in addition to complex decongestive therapy (CDT) on the management of patients with a breast cancer-related lymphedema (BCRL).
METHODS
Fifty outpatients (average age of 56.2 ± 2.7 years, range 28-71) with a BCRL were enrolled for this study. Patients were randomly assigned (1:1 ratio) to receive either CDT consisting of skin care, manual lymphatic drainage, remedial exercises, and elastic compression garment (control group, n = 25) or CDT plus Linfadren® (study group, n = 25). Patients were evaluated before and after treatment and 3 months after the end of treatment. Primary outcomes were reduction of upper limb excess volume (EV) and percentage reduction of excess volume (%REV). Secondary outcomes were improvement in Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) questionnaire, and patient's perception of treatment effectiveness (PPTE).
RESULTS
Addition of Linfadren® to CDT yielded an additional reduction of primary outcomes both after treatment (EV, - 521 ml vs. - 256 ml, P < 0.0001; %REV, - 66.4% vs. - 34%, P = 0.02) and at 3-month follow-up (EV, - 59 ml vs. + 24 ml, P < 0.0001; %REV, - 73.6% vs. - 31.4%, P = 0.004). Moreover, statistically significant differences were found between the two groups for the secondary outcomes after treatment (QuickDASH, P = 0.006; PPTE, P = 0.03) and at 3-month follow-up (QuickDASH, P = 0.006; PPTE, P = 0.02). No patient showed adverse events.
CONCLUSIONS
Linfadren® in addition to CDT was a safe and effective therapy for reducing BCRL and was better than CDT alone.
