PURPOSE: To investigate whether termination of bisphosphonates (BPs) affects resolution of bone exposure and symptomatic disease in patients with established medication-related osteonecrosis of the jaw (MRONJ).
PATIENTS AND METHODS: The studied population included 84 patients with established MRONJ who discontinued BP therapy before treatment (n = 21), at treatment initiation (n = 38), or later (or never) in the treatment course (n = 25). These 3 groups were compared using Kaplan-Meier curves and log-rank tests for differences in the respective times to resolution of 1) bone exposure for any treatment modality, 2) bone exposure not requiring radical surgery, and 3) disease symptoms.
RESULTS: Patients who continued BPs after the start of treatment exhibited significantly delayed resolution of symptoms (median 12 months; 95% confidence interval 8 to 15) compared with those who discontinued BPs before (3 months; 2 to 5) and at (6 months; 3 to 7) presentation (P < .005).
CONCLUSIONS: Independent of treatment modality and MRONJ stage at presentation, discontinuing BP before or at treatment initiation is associated with faster resolution of MRONJ symptoms compared with continuing the drug throughout jaw treatment. Patients should be counseled that continuing their BP medication after an established MRONJ diagnosis (compared to stopping the BP at diagnosis) may delay resolution of maxillofacial symptoms by approximately 6 months.
