The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) is a cancer-specific HRQL instrument and consists of 30 items. Two items reflect overall global health status. The remaining items are divided into five functional and nine symptom scales.The EORTC head and neck cancer module (QLQ-H&N35) is designed to be used in combination with the EORTC QLQ-C30 and focuses on issues specific for the HNC population. It consists of 35 items divided into seven symptoms scales and eleven single items.Items are responded to using Likert scales and responses are converted into scores from 0 to 100. Higher scores reflect better HRQL on the functional scales and higher levels of symptoms on the symptoms scales [All of the above-mentioned HRQL instruments are considered reliable, valid, and are used both in clinical and research settings.
