Although their efficacy in reducing skeletal related events is important in the supportive management of the myeloma patient, post-marketing experience with this class of agents, particularly the more potent intravenous agents pamidronate and zoledronic acid, have raised cautionary notes regarding the potential side effects of these agents. The focus of this session is to review the risk factors, incidence, prevention strategies and management of bisphosphonate-related osteonecrosis of the jaw. In addition, pathophysiology, incidence and monitoring for renal dysfunction during chronic therapy with these agents are reviewed.

Epidemiologic and experimental studies have suggested the combination of bisphosphonates and dexamethasone results in osteonecrosis of the jaw more often than either agent alone. The goal of this study was to assess the combination of these 2 drugs in a large animal model previously shown to be susceptible to exposed bone in the oral cavity when treated with bisphosphonates. Skeletally mature beagle dogs were untreated controls or treated with zoledronic acid (ZOL), dexamethasone (DEX), or ZOL plus DEX. ZOL and DEX were given at doses based on those used in humans. All animals underwent single molar extraction at 7 and 8 months after the start of the study. Extraction sites were obtained at month 9 for assessment of osseous healing using micro-computed tomography and histology. No animals were observed to have exposed bone after dental extraction, yet 1 animal treated with ZOL and 1 treated with ZOL plus DEX had severely disrupted extraction sites as viewed by computed tomography and histology. These 2 animals had an intense periosteal reaction that was less obvious but still present in all ZOL-treated animals and absent from untreated animals. There was no significant difference in bone volume within the socket among groups at 4 or 8 weeks after healing, yet the ratio of surface to volume was significantly higher in animals treated with ZOL plus DEX at 8 weeks compared with control animals. These findings suggest a more complex pathophysiology to osteonecrosis of the jaw than is implied by previous epidemiologic studies and those in rodents and raise questions about the potential role of DEX in its etiology.

The patient had initially presented to a dentist after experiencing pain and "stiffness" of her jaw on the left side. A diagnosis of myofascial pain syndrome was made, and the patient was treated with a soft diet and a nonsteroidal antiinflammatory agent. However, over the course of the next 3 weeks the pain and trismus progressively worsened and was now associated with a left preauricular swelling. The patient was referred to an otolaryngologist, who made the presumptive diagnosis of acute parotitis and placed the patient on a first generation cephalosporin. During the following 2 weeks, the left facial swelling and pain worsened significantly despite her compliance wilh the antibiotic regimen. At that time, she presented to our institution for further evaluation.

Due to the relatively low incidence of ONJ, these studies necessitate the use of specimens from patients who have had ONJ for various durations. The goal of this study was to determine if properties, specifically bone morphology assessed by micro-computed tomography (micro-CT), were influenced by the duration of ONJ. Sequestra from 31 patients with confirmed ONJ for between 3 weeks and 42 months prior to obtaining the tissue were scanned using micro-CT to determine bone volume/tissue volume (BV/TV) and bone surface/volume (BS/TV). There was no significant correlation between the sequestra bone morphology (either BV/TV or BS/ TV) and the duration of ONJ. We interpret this as evidence that studies should not be concerned about assessing tissue properties from patients that have had ONJ for different durations. Furthermore, the lack of difference in morphology with continued duration of ONJ suggests that the majority of changes to the bone tissue occur early on in the disease progression.

Computed tomography could represent a useful tool for early detection of BRONJ, yet its effectiveness would necessitate changes in tissue density. The aim of this study was to quantify bone matrix density of tissue from patients with BRONJ. Patients and Methods: Bone samples from 13 patients with confirmed BRONJ were scanned by use of high-resolution micro-computed tomography. Mean density and density distribution were assessed and compared with mandible samples from cadaveric controls (n ϭ 8; age range, 43-94 years). Results: The bone matrix in BRONJ samples had a significantly higher mean density (ϩ8.5%, P ϭ .01) compared with cadaveric samples. The higher density in BRONJ tissue was evident in a clear shift in the tissue density profile. In controls, less than 5% of the tissue had a density above the median gray-scale value, whereas on average, BRONJ tissue had approximately 15% of the tissue density in this range. By use of z score analyses of mean density values, a large degree of heterogeneity is evident among BRONJ specimens, with some samples having z scores of 0 and others having z scores well above 6 compared with controls. Conclusions: On the basis of these findings, higher tissue density appears to manifest in only a subset of BRONJ patients, suggesting that density may have limitations as a biomarker for early detection of this condition.

A retrospective cohort multicenter study was designed. Patients from the University of Tennessee Medical Center, New York University Medical Center, and New York Center for Orthognathic and Maxillofacial Surgery were enrolled who had been treated with intravenous bisphosphonate medications for an underlying diagnosis of cancer and who had been clinically diagnosed with bisphosphonate-related osteonecrosis of the jaws (BRONJ). The institutional review boards approved the present study. The primary predictor variable was the clinical presence of BRONJ. The primary outcome variable was the microscopic presence of metastatic cancer in the osteonecrotic jaw specimens. A total of 744 sites of BRONJ were clinically diagnosed. Of these sites, 552 (74%) were diagnosed in patients who had received intravenous bisphosphonate medications. Of these 552 sites, 357 (65%) underwent microscopic evaluation through biopsy, sequestrectomy, or resection with curative intent. Of the 357 sites of BRONJ subjected to microscopic analysis, 19 (5.3%) sites were diagnosed with 20 cancers in 16 patients. Albeit rare, the presence of cancer in a BRONJ specimen represents 1 explanation for the development of osteonecrosis in patients exposed to intravenous bisphosphonate medications in whom a clinical diagnosis of BRONJ has been applied. Additional molecular information is needed to provide an explanation for this observation.

The efficacy of these agents in treating and preventing the significant skeletal complications associated with these conditions has had a major positive impact for patients and is responsible for their widespread use in medicine. Despite these benefits, osteonecrosis of the jaws has recently emerged as a significant complication in a subset of patients receiving these drugs. Based on a growing number of case reports and institutional reviews, bisphosphonate therapy may cause exposed and necrotic bone that is isolated to the jaw. This complication usually presents following simple dento-alveolar surgery, and can cause a significant adverse effect on the quality of life for most patients. The pathogenesis for this complication appears to be related to the profound inhibition of osteoclast function and bone remodeling.
