Clinical trials

This prospective observational cohort study aims to develop and evaluate an early warning and risk prediction model for medication-related osteonecrosis of the jaw (MRONJ) based on multimodal data fusion. Eligible participants will include adults who have received bone-modifying agents, including bisphosphonates or denosumab, for at least 24 months for osteoporosis or bone metastases and who are scheduled to undergo clinically indicated invasive oral procedures. The study will not assign any treatment or intervention. All oral procedures will be performed as part of routine clinical care. Clinical characteristics, medication exposure, oral examination findings, cone-beam computed tomography imaging data, and biological samples including saliva, blood, urine, and gingival crevicular fluid will be collected. Proteomic and metabolomic analyses will be performed to identify candidate biomarkers associated with MRONJ risk. Participants will be followed prospectively after the oral procedure to assess wound healing, clinical symptoms, imaging changes, and the occurrence of MRONJ. The study will evaluate whether a multimodal model combining clinical, imaging, and biological data can predict the risk of MRONJ after invasive oral procedures.

The goal of this \[type of study:clinical trial\] is to \[learn about\] in \[Clinical IVB stage oral squamous cell carcinoma patients\]. The main question it aims to answer are: • \[Observing the effectiveness and safety of the combination of Adebrelimab and TP regimen in neoadjuvant therapy for clinical IVB stage oral squamous cell carcinoma patients\] Participants will \[Received treatment with Adebrelimab combined with TP regimen, followed by surgery after 2 cycles of neoadjuvant therapy. After surgery, radiotherapy and chemotherapy combined with immunotherapy were chosen based on the patient\'s condition, with a total follow-up of two years.\].

The purpose of this study is to investigate the survival benefit of neoadjuvant anti-PD-1 immunotherapy plus TP chemotherapy compared with TP chemotherapy or up-front surgery in resectable locally advanced oral squamous cell carcinoma.
