Background This study investigates cutoff scores for the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire‐Core 30‐questions (EORTC QLQ‐C30) and head and neck cancer‐specific module (QLQ‐H&N35) to identify patients with head and neck cancer who may require clinical attention. Methods Ninety‐six patients with head and neck cancer completed the EORTC QLQ‐C30/H&N35 and questions on supportive care needs. For all EORTC domains with the ability to discriminate between patients with and without unmet needs (area under the receiver operating characteristic curve [AUC] ≥0.70), the accuracy (eg, sensitivity and specificity) of potential cutoff scores were calculated. Results Cutoff scores (sensitivity ≥0.80 and specificity ≥0.60) of 90 (functioning domains) and 5 to 10 (symptom domains) were found on 7 of 28 continuous EORTC QLQ‐C30/H&N35 domains. Borderline cutoff scores (sensitivity ≥0.70 and specificity ≥0.60 or sensitivity ≥0.80 and specificity ≥0.50) were found on 5 other domains. Conclusions This study provided cutoff scores on the EORTC QLQ‐C30 and H&N35 based on patients' perceptions of their needs for supportive care. Future research is needed on the replicability of these cutoff scores. © 2015 Wiley Periodicals, Inc. Head Neck 38 : E1493–E1500, 2016
