Abstract

Background: Medication-related osteonecrosis of the jaw (MRONJ) is a challenging condition often associated with long-term use of anti-resorptive medications. Accurate diagnosis is essential, but predicting the prognosis is particularly difficult due to the high likelihood of recurrence after surgery. This study assesses the utility of quantitative values from bone SPECT/CT as predictors of surgical outcomes in MRONJ patients.

Materials and methods: We analyzed a cohort of 57 MRONJ patients who underwent surgical treatment. Preoperative bone SPECT/CT scans were used to obtain the maximal SUV (SUVmax) of MRONJ lesions and the ratio of the SUVmax to the mean SUV of a reference region (rSUVmax). Logistic regression analysis was performed to evaluate the relationship between preoperative SUVmax and rSUVmax and surgical outcomes, adjusting for confounders such as age, sex, diabetes, type of bone-modifying agent, MRONJ-affected sites, and stage.

Results: Both SUVmax and rSUVmax values increased with the progression from MRONJ stage 1 to stage 3 and were higher in the No Resolution group compared to the Complete Resolution group. Multivariate logistic regression analysis revealed that higher rSUVmax values were significantly associated with poor surgical outcomes (OR, 1.51; 95% CI, 1.07-2.14), whereas SUVmax values were not significantly associated (OR, 1.05; 95% CI, 0.98-1.13). Preoperative MRONJ stages did not significantly predict MRONJ resolution.

Conclusion: rSUVmax from bone SPECT/CT may serve as a valuable prognostic tool for assessing MRONJ severity and predicting surgical outcomes. Incorporating rSUVmax measurements into clinical practice could enhance decision-making and improve patient management.

Clinical trial registration: None.

期刊介绍： EJNMMI Research publishes new basic, translational and clinical research in the field of nuclear medicine and molecular imaging. Regular features include original research articles, rapid communication of preliminary data on innovative research, interesting case reports, editorials, and letters to the editor. Educational articles on basic sciences, fundamental aspects and controversy related to pre-clinical and clinical research or ethical aspects of research are also welcome. Timely reviews provide updates on current applications, issues in imaging research and translational aspects of nuclear medicine and molecular imaging technologies. The main emphasis is placed on the development of targeted imaging with radiopharmaceuticals within the broader context of molecular probes to enhance understanding and characterisation of the complex biological processes underlying disease and to develop, test and guide new treatment modalities, including radionuclide therapy.
