A rare complication of prolonged bisphosphonate treatment: The osteonecrosis of jaw in a patient with metastatic prostate cancer

Abstract

Bisphosphonates are frequently used for the treatment of bone metastases. We described a 71 years old male with the previous diagnosis of bone metastatic prostate cancer and who underwent hormonotherapy combined with zolendronic acid treatment during 7.5 years and presented the complaints of severe jaw pain and inability of chewing. It was determined that the findings of increased PSA with osteonecrotic area on jaw at radiological imaging. He was urgently diagnosed with the diagnosis of osteonecrosis of jaw related to the long-term zolendronic acid treatment. Bisphosphonate treatment was stopped, and he was treated with conservative treatment, and the disorder was improved by this management. This unclear disorder is required more detailed studies on the terms of ethiology, treatment style, follow-up at the treatment period, and management of complications with the aim of applying these agents more safely.
