A nomogram for patients with early-stage upper aerodigestive tract natural killer/T-cell lymphoma. To use the nomogram, an individual patient’s value is located on each variable axis, and a line is drawn upward to determine the number of points received for each variable value. The sum of these numbers is located on the total points axis, and a line is drawn downward to the survival axes to determine the likelihood of 5-year OS (a) and PFS (b) rates. Site primary site of the lymphoma, LDH pretreatment level of serum lactate dehydrogenase, ECOG eastern cooperative oncology group, LN regional lymph node
