Fig. 1From: Pretreatment prognostic factors of survival and late toxicities for patients with nasopharyngeal carcinoma treated by simultaneous integrated boost intensity-modulated radiotherapySurvival comparisons of NPC patients by different pretreatment biomarkers based on the cutoff point through ROC curve analysis: (a) Failure-free survival for those with monocyte percentage < 7.2% vs. ≥ 7.2%; (b) Overall survival for those with L/M ratio ≥ 4.3 vs. < 4.3; (c) Locoregional relapse-free survival for those with gross tumor volume < 67.5 ml vs. ≥ 67.5 mlBack to article page
