From: A nomogram to predict lymph node metastasis risk for early esophageal squamous cell carcinoma
Nomogram to predict the LNM risk for each patient. The patient’s nomogram calculated the risk of LNM as 59%. Nomogram calculations are as follows: size ≥2.5 cm, which corresponds to 61 points; low differentiation, which corresponds to 100 points; pT1b, which corresponds to 85 points; this equals 246 total points, corresponding to a LNM rate of 59%
