Patient-reported outcomes in immunotherapy for head and neck cancer

BackgroundData about patient-reported outcomes (PROs) among patients with head and neck squamous cell carcinoma (HNSCC) treated with immune checkpoint inhibitors are sparse. Our exploratory study evaluated PROs in patients with HNSCC starting treatment with immune checkpoint inhibitor monotherapy or combination therapy with cetuximab. MethodsPatients were recruited prior to receipt of their first checkpoint inhibitor therapy infusion. Participants completed measures of checkpoint inhibitor toxicities and quality of life (QOL) at on-treatment clinic visits. ResultsAmong patients treated with checkpoint inhibitor monotherapy (n = 48) or combination therapy (n = 38) toxicity increased over time (p < 0.05), while overall QOL improved from baseline to 12 weeks, with stable or declining QOL thereafter (p < 0.05). There were no group differences in change in toxicity index or QOL. Toxicity index scores were significantly higher in the combination group at 18-20 weeks and 6 months post-initiation of immune checkpoint inhibitor (p < 0.05). There were no significant group differences at baseline, the 6-8 week (p = 0.13) or 3-month (p = 0.09) evaluations. The combination group reported better emotional well-being at baseline than the monotherapy group (p = 0.04), There were no other group differences QOL at baseline or later timepoints. ConclusionsDespite increasing patient-reported toxicity, checkpoint inhibitor monotherapy and combination therapy were associated with similar transient improvements, then worsening, of QOL in patients with HNSCC.

Automated summary

This study examined patient-reported outcomes among patients with head and neck squamous cell carcinoma (HNSCC) treated with immune checkpoint inhibitors. The results showed that although toxicity increased over time, overall quality of life improved after 12 weeks of treatment and then remained stable or declined. There were no significant differences in quality of life or toxicity between monotherapy and combination therapy.
