Purpose: Bisphosphonates (BPs) effectively treat metastatic bone disease, hypercalcemia, and osteoporosis. BP exposure, however, may be associated with osteonecrosis of the jaw (ONJ). The aim of the present study was to estimate the magnitude of the association between intravenous (IV) BP exposure and ONJ, and to identify potential confounders.
Materials And Methods: Using a case-control study design, the investigators identified and adjudicated a sample of cases with ONJ and matched them randomly with 5 controls per case. The controls were matched to cases on age, gender, cancer type, and date of cancer diagnosis. The medical records were abstracted and data on BP exposure, cancer therapy, and comorbidities were recorded. Statistical analyses were carried out using conditional logistic regression in Stata 9.0 (Stata Corp, College Station, TX).
Results: Thirty cases of ONJ were identified at Massachusetts General Hospital from February 2003 through February 2007. Zoledronate was found to confer significant risk toward development of ONJ (adjusted odds ratio = 31.8, P < .05). Although a trend toward increased risk was noted for pamidronate, this association was not significant after controlling for zoledronate. Obesity and smoking were associated significantly with ONJ development, whereas oral BPs had no effect.
Conclusion: In this study, cancer patients who had received zoledronate exhibited a significant 30-fold increase in their risk to develop ONJ. More studies are needed to elucidate the exact role of obesity and smoking in the development of ONJ, and the complex interactions of IV BPs with other chemotherapies during cancer treatment.

Objective: Cyclin-dependent kinase (CDK)-4/6 inhibitors have significantly improved outcomes in several cancers but can also induce various organ system toxicities, including musculoskeletal disorders. This study aimed to comprehensively characterize the musculoskeletal adverse events (MSAEs) associated with CDK4/6 inhibitors based on real-world data.
Methods: Reports of MSAEs linked to CDK4/6 inhibitors from the first quarter (Q1) of 2015 and 2023 Q4 were extracted from the FAERS.

Background/purpose: Bisphosphonate-related osteonecrosis of the jaw (BRONJ), a complication arising from the use of bisphosphonates (BPs), inflicts long-term suffering on patients. Currently, there is still a lack of effective treatments. This study aimed to explore the preventive effects of propranolol (PRO) on BRONJ in vitro and in vivo, given PRO's potential in bone health enhancement.

Background: Medication-related osteonecrosis of the jaw (MRONJ) is a rare but potentially severe condition that significantly affects the quality of life of patients with cancer. This study evaluated MRONJ in patients with cancer treated with zoledronic acid (ZOA) and denosumab (Dmab).
Methods: The survey investigated patients who were diagnosed with MRONJ at the Department of Oral and Maxillofacial Surgery after receiving either ZOA or Dmab at the Saitama Medical Center, Saitama Medical University, between April 1, 2022, and March 31, 2023.

Objectives: In advanced stages of osteoradionecrosis, medication-related osteonecrosis of the jaw, and osteomyelitis, a resection of sections of the mandible may be unavoidable. The determination of adequate bony resection margins is a fundamental problem because bony resection margins cannot be secured intraoperatively. Single-photon emission computed tomography (SPECT-CT) is more accurate than conventional imaging techniques in detecting inflammatory jaw pathologies.

Rationale: Osteoporosis is an abnormal reduction in bone mass and bone deterioration, leading to increased fracture risk. Alendronate belongs to the bisphosphonate class of drugs, which inhibit bone resorption by interfering with the activity of osteoclasts (bone cells that break down bone tissue). This is an update of a Cochrane review first published in 2008.
