Prognostic Nomograms for Predicting Overall Survival and Cancer‐Specific Survival of Patients With Malignant Pheochromocytoma and Paraganglioma

Abstract: BackgroundMalignant pheochromocytoma and paraganglioma (PPGL) are rare tumors with few prognostic tools. This study aimed to construct nomograms for predicting 3- and 5-year survival for patients with malignant PPGL.MethodsThe patient data was retrieved from the Surveillance, Epidemiology, and End Results (SEER) database. A total of 764 patients diagnosed with malignant PPGL from 1975 to 2016 were included in this study. The patients were randomly divided into two cohorts; the training cohort (n = 536) and the… Show more

“…A clinical nomogram is a valid and reliable prediction model that combines multiple prognostic factors to accurately calculate and predict individual survival ( 25 ). Nomograms have been used extensively in many previous studies, such as those on oropharyngeal cancer ( 26 ), young breast cancer ( 27 ), low-grade endometrial stromal sarcoma ( 28 ), and both malignant pheochromocytoma and paraganglioma ( 29 ). In terms of liver cancer, a nomogram has been constructed to predict OS in PHNET cases by Zhang et al ( 13 ); however, this report did not take into account the effect of competing events on PHNET-specific death, which lowered the confidence of the results.…”
