N2 - Objectives. Radiation therapy (RT), with or without chemotherapy,can cause significant acute toxicity amongpatients treated for head and neck cancer (HNC), but predicting,before treatment, who will experience a particulartoxicity or symptom is difficult. We created and evaluated 2multivariate models and generated a nomogram to predictsymptom severity during RT based on a patient-reportedoutcome (PRO) instrument, the MD Anderson SymptomInventory-Head and Neck Module (MDASI-HN).Study Design. This was a prospective, longitudinal, questionnairebasedstudy.Setting. Tertiary cancer care center.Subjects and Methods. Subjects were 264 patients with HNC(mostly oropharyngeal) who had completed the MDASI-HNbefore and during therapy. Pretreatment variables were correlatedwith MDASI-HN symptom scores during therapywith multivariate modeling and then were correlated withthe composite MDASI-HN score during week 5 of therapy.Results. A multivariate model incorporating pretreatmentPROs better predicted MDASI-HN symptom scores duringtreatment than did a model based on clinical variables andphysician-rated patient performance status alone (Akaike informationcriterion = 1442.5 vs 1459.9). In the most parsimoniousmodel, pretreatment MDASI-HN symptom severity (P<.001), concurrent chemotherapy (P = .006), primary tumor site(P = .016), and receipt of definitive (rather than adjuvant) RT(P = .044) correlated with MDASI-HN symptom scores duringweek 5. That model was used to construct a nomogram.Conclusion. Our model demonstrates the value of incorporatingbaseline PROs, in addition to disease and treatmentcharacteristics, to predict patient symptom burden duringtherapy. Although additional investigation and validation arerequired, PRO-inclusive prediction tools can be useful forimproving symptom interventions and expectations forpatients being treated for HNC.
