Fig. 3From: Prognostic relevance of topoisomerase II α and minichromosome maintenance protein 6 expression in colorectal cancerKaplan-Meier survival analysis of the cumulative overall survival (a, c) and progression-free survival (b, d) of patients with colorectal carcinoma stratified by the UICC stages I + II, III and IV. Each subset was analysed in respect to topoisomerase II α (a, b) and minichromosome maintenance protein 6 expression (c, d). P-values were calculated by Log rank testsBack to article page
