What was measured

EORTC QLQ-C30 is a questionnaire to assess the overall QoL of cancer patients. Participant responses to questions regarding GHS ("How would you rate your overall health during the past week?") and QoL ("How would you rate your overall quality of life during the past week?") were scored on a 7-point scale (1= Very poor to 7=Excellent). The combined score of GHS (Item 29) and QoL (Item 30) were computed by averaging the raw scores of the 2 items and then applying a linear transformation to standardize the average score, so that the combined scores ranged from 0-100. A higher score indicated a better outcome. Per protocol, the change from baseline in GHS and QoL 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-C30 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).
