Five-year survival in different tumor stages by frailty status. Kaplan-Meier plots of 5-year survival in frail versus nonfrail patients are stratified according to TNM classification of malignant tumors (TNM) stage. (A): TNM stages 0–II (localized disease; n = 108; log rank p < .001). (B): TNM stage III (regional disease; n = 45; log rank p = .007). (C): TNM stage IV (distant mestastases; n = 21; log rank p = .2).
