What was measured

EORTC QLQ-H\&N35 is a 35-item questionnaire to assess QoL of head and neck cancer participants and consists of 7 multi-item scales (pain in the mouth, problems with swallowing, senses, speech, social eating, social contact, and sexuality). Participant responses to the pain scale (Items 31-34) were scored on a 4-point scale (1=Not at all to 4=Very much). Raw scores were standardized by linear transformation so that scores ranged from 0 to 100; a higher score indicated more problems. Per protocol, the change from baseline in EORTC QLQ-H\&N35 pain symptoms (Items 31-34) combined score for all randomized participants in the pembrolizumab + SOC arm was presented.

Analysis population: All randomized participants in the pembrolizumab + SOC treatment group who received at least one dose of study treatment and had at least one EORTC QLQ-H\&N35 assessment data available for this outcome measure at Baseline and at Week 4. Per protocol, this outcome measure was only reported in participants in the pembrolizumab + SOC arm.

Groups in this outcome

Pembrolizumab + Standard of Care (SOC)

Neoadjuvant treatment: Participants received 200 mg pembrolizumab by intravenous (IV) infusion administered on Day 1 of a 21-day cycle for 2 cycles (up to 6 weeks) prior to surgery. Adjuvant treatment: Following surgical resection, participants received 200 mg pembrolizumab, IV infusion, on Day 1 of a 21-day cycle for 15 cycles (up to 45 weeks) plus investigator's choice of SOC treatment regimen consisting of radiotherapy, with or without cisplatin 100 mg/m\^2, IV infusion, on Day 1 of a 21-day cycle for 3 cycles (up to 9 weeks).

Standard of Care (SOC)

Adjuvant treatment: Following surgical resection, participants received investigator's choice of SOC treatment regimen consisting of radiotherapy, with or without cisplatin 100 mg/m\^2, IV infusion, on Day 1 of a 21-day cycle for 3 cycles (up to 9 weeks).
