Univariate and Multivariate Analyses of Factors Associated with Local Tumor Progression by Using the Competing-Risks Regression Model
Note.—All examined variables displayed significance at univariate analysis; however, only the biopsy result and the minimal margin size maintained significance at multivariate analysis. Multivariate analysis data were calculated with the competing-risks model. N = necrotic-negative biopsy, V = viable-tumor positive biopsy.
