From: Pretreatment platelet count improves the prognostic performance of the TNM staging system and aids in planning therapeutic regimens for nasopharyngeal carcinoma: a single-institutional study of 2,626 patients

Figure 3

Receiver operating characteristic (ROC) curves for survival prediction with TNM classification alone (stages I–II and III–IV) or with the addition of pretreatment platelet count ( ≤300 × 10 9 /L and >300 × 10 9 /L) to TNM classification in the 2,626 patients with nasopharyngeal carcinoma. A, overall survival. B, locoregional recurrence–free survival. C, distant metastasis–free survival. The P value was the comparison of area under the curves (AUCs) between the addition of platelet count to TNM classification and TNM classification alone.
