Objective: To summarize the clinical features of osteonecrosis of the jaw (ONJ) in multiple myeloma (MM) patients treated with bisphosphonate.
Methods: The clinical data of 4 patients with bisphosphonate-related (ONJ) in MM were reported and literatures were reviewed.
Results: In these patients, 3 males and 1 female, aged 59-73, pamidronate combined with chemotherapy, high dose glucocorticosteroid, and anti-angiogenic drug had been used for 12-44 months before the occurrence of ONJ. In treatment of ONJ conservative debridement of necrotic bone, systematic use of antibiotics, use of chlorhexidine acetate gargle, and withdrawal of bisphosphonates were preferable to aggressive surgical measures.
Conclusion: Long-term use of bisphosphonates combined with chemotherapy in MM may cause ONJ that involves both mandible and maxilla. No satisfactory therapy is currently available.
