Oral Complications of Chemotherapy and Head/Neck Radiation (PDQ®): Supportive care - Health Professional Information [NCI] - Oral Toxicities Not Related to Chemotherapy or Radiation Therapy

It is advisable to discuss with the patient's physician whether discontinuing bisphosphonate therapy will not put the patient's general health at risk. Obtaining an informed consent from the patient before execution of the proposed drug discontinuation and therapy is important.

Spontaneous and asymptomatic BON

Patients may present with asymptomatic exposed necrotic bone anywhere in the oral cavity, although the mylohyoid plate on the posterior mandible and the mandibular tori are the most frequently affected sites. In this case, local measures and effective oral hygiene are important, as is systematic reevaluation of the patient to ensure resolution.

Effects on quality of life

The number of patients who develop BON is small compared with the large number of people who take bisphosphonates. However, some lesions can progress to large sizes and cause severe changes in a patient's quality of life.[1,2] Advanced mandibular lesions, for instance, can cause necrosis of the cortical bone, increasing the risk of fractures.[1] Advanced and nonresponsive infections may require hospitalization and intravenous antibiotic therapy.[1] Advanced cases of BON may require extensive jawbone resection.[29] Therefore, this adverse effect of bisphosphonate therapy may negatively affect quality of life.

New trends

The discontinuation of tobacco use to favor the healing process has been recommended.[30] (Refer to the PDQ summary on Smoking in Cancer Care for more information.) However, the role of tobacco and other comorbidities in the process of BON formation requires further investigation.[9] Several cases of oral osteonecrosis have been reported with drugs other than bisphosphonates, including the following:[31,32]

  • A human monoclonal antibody that inhibits the receptor activator of nuclear factor kappa beta ligand and is under investigation.
  • The antiangiogenic drugs being tested in advanced cancer cases, including bevacizumab, sunitinib, and sorafenib.
