Slieker FJB, et al. - In this investigation involving 95 patients, researchers created prediction models that calculate postoperative 2- and 5-year mortality probabilities among patients with squamous cell carcinoma of the maxilla (MSCC). Between 2000 and 2015, data were collected from the medical records of patients who had undergone surgery for MSCC. To evaluate calibration and discriminatory ability, internal validation was performed. Participants in the study were patients with MSCC. Mortality was associated with age, neck treatment, surgical margins, bone invasion, spindle growth, and vasoinvasive growth. Findings suggested that new prediction models can be used to calculate the MSCC-specific mortality probability.
