Abstract: BACKGROUND: In the PLATINUM (ClinicalTrials.gov: NCT03984357) trial, nivolumab plus chemoradiotherapy sparing concurrent cisplatin demonstrated efficacy and safety in nasopharyngeal carcinoma (NPC). Herein, patient-reported outcomes (PROs) on quality of life (QoL), tolerability, and social reintegration are reported. METHODS: Patients with T4N1M0/T1-4N2-3M0 NPC were assessed for general and head-and-neck-specific QoL (using the European Organization for Research and Treatment of Cancer and the Functional Assessment of Cancer Therapy) and tolerability (using the PRO-specific Common Terminology Criteria for Adverse Events). Analyses included change over time, effect of the treatment phase on QoL, time-to-event analysis, and a comparison of PROs and clinician-reported outcomes (CROs) in toxicity. FINDINGS: Among 152 patients, 44.1% achieved social reintegration, and 51.3% were satisfied with their current life. Radiotherapy dominated QoL deterioration rather than induction chemotherapy (pooled mean difference, -18.51; 95% confidence interval [CI], -29.50 to -7.52; p = 0.001), and its removal dominated QoL improvement rather than that of nivolumab (pooled mean difference, -7.62; 95% CI, -10.05 to -5.19; p < 0.001). Patients without social reintegration had greater deterioration in speech (hazard ratio [HR], 0.60; 95% CI, 0.38 to 0.94; p = 0.027) and swallowing functions (HR, 0.59; 95% CI, 0.39 to 0.89; p = 0.011). Under-reporting of decreased appetite severity by CROs vs. by PROs in all three treatment phases was associated with poorer social reintegration (p = 0.002) and reduced failure-free survival (3 years, 86.1% vs. 95.0%; p = 0.021). CONCLUSIONS: Social reintegration is a practical composite indicator of favorable PROs in NPC. Interventions targeting speech, swallowing, and decreased appetite might promote better recovery.
