متن کاملA prognostic nomogram for prediction of recurrence in desmoid fibromatosis.
OBJECTIVE To construct a postoperative nomogram to estimate the risk of local recurrence for patients with desmoid tumors. BACKGROUND The standard management of desmoid tumors is resection, but many recur locally. Other options include observation or novel chemotherapeutics, but little guidance exists on selecting treatment. METHODS Patients undergoing resection during 1982-2011 for primary...
متن کاملDevelopment and validation of a prognostic nomogram for IgA nephropathy
IgA nephropathy (IgAN) shows strong heterogeneity between individuals. IgAN prognosis is associated with pathological lesions and clinical indicators. However, simple tools for evaluating the clinical prognosis remain inadequate. Our objective was to develop an intuitive estimation tool for predicting the IgAN prognosis. 349 patients with IgAN at The Chinese People's Liberation Army General Hos...
