|
| E.2.2 | Secondary objectives of the trial |
(1)Pain scores (spontaneous and functional, i.e. while chewing and swallowing of a standardized portion of food , e.g. a cracker) during the 5 days of treatment, obtained using a “Pain Diary”and a once daily phone interview. (2)Multidimensional assessment of pain at the oral lesion using the ‘German Pain Questionnaire’ (DSF). (3)Presence and severity of central (nausea, vomiting, sedation) and local (burning, dry mouth) opioid-related side effects. (4)Dose and timing of the current, standard medication for treatment of pain
