Development and validation of novel nomograms to predict survival of patients with tongue squamous cell carcinoma

Figure 2 Nomograms predicting the 3- and 5-year overall survival and cancer-specific survival in patients with squamous cell carcinoma of the tongue. A: Nomogram predicting the 3- and 5-year overall survival (OS) in patients with squamous cell carcinoma of the tongue (TSCC); B: Nomogram predicting the 3- and 5-year cancer-specific survival (CSS) in patients with TSCC. The points for each variable were summed, and the probabilities of 3- and 5-year OS and CSS were predicted based on the total number of points (shown at the bottom of the nomogram). For example, consider a 60-year-old unmarried patient with moderately differentiated T2 and N1 stage cancer on the anterior 2/3 of tongue who underwent neck dissection and postoperative chemotherapy. Top red lines represent the points for each variable, the sum (209) of these points is the total score, and the bottom red line indicates the probabilities of 3- (64%) and 5-year (55%) overall survival.
