Abstract
Simple SummaryElderly patients with recurrent or metastatic head and neck squamous cell carcinoma are a unique subset because they are at increased risks of miserable prognosis. Although cisplatin, 5-fluorouracil plus cetuximab (EXTREME) is the most commonly used regimen, chemotherapy de-escalation strategy was suggested in elderly patients due to toxicity. Herein, an oral tegafur–uracil is usually substituted for 5-fluorouracil and combined with cisplatin plus cetuximab (UPEx) as a novel agent for elderly patients with recurrent or metastatic head and neck squamous cell carcinoma. The median progression-free survival was 5.4 months in UPEx and 5.8 months in EXTREME (p = 0.451). The median overall survival was 10.8 months in UPEx and 10.2 months in EXTREME (p = 0.807). Grade 3/4 adverse events were much fewer in UPEx than in EXTREME (p < 0.001). Our study demonstrated that UPEx is effective with improving safety profiles. We suggested UPEx might be a better treatment option for elderly patients with recurrent or metastatic head and neck squamous cell carcinoma.There are increasing incidences of elderly patients with recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC). However, the treatment is not yet established. We conducted a propensity score matching analysis to evaluate the efficacy and safety of tegafur–uracil versus 5-fluorouracil in combination with cisplatin plus cetuximab in elderly patients with R/M HNSCC. Elderly patients with R/M HNSCC treated with cetuximab-containing chemotherapy were recruited into this study. In order to reduce the selection bias, propensity score matching was performed. Kaplan–Meier curves were plotted for progression-free survival (PFS) and overall survival (OS). Toxicities were graded according to the National Cancer Institute’s Common Terminology Criteria V3.0. After propensity sore matching, 54 patients with tegafur–uracil, cisplatin plus cetuximab (UPEx), and 54 patients with 5-fluorouracil, cisplatin plus cetuximab (EXTREME) were identified. The median PFS was 5.4 months in UPEx and 5.8 months in EXTREME (p = 0.451). The median OS was 10.8 months in UPEx and 10.2 months in EXTREME (p = 0.807). The overall response rate (ORR) and disease control rate (DCR) were insignificant in both arms, accounting for 61% versus 59% (p = 0.680) and 72% versus 70% (p = 0.732) in the UPEx arm and the EXTREME arm, respectively. A multivariate analysis showed that age and ECOG PS were, independently, predictors. Grade 3/4 adverse events were much fewer in UPEx than in EXTREME (p < 0.001). Both cetuximab-containing chemotherapies are effective in elderly patients with R/M HNSCC. Safety profiles are improved when tegafur–uracil is substituted for 5-fluorouracil. Further prospective studies are warranted to validate our conclusions.

Head and neck squamous cell carcinoma is the sixth most common cancer worldwide [1]
Baseline characteristics were presented in Eastern Cooperative Oncology Group Performance Status (ECOG PS) of 2
Our study showed that UPEx is an effective regimen with tolerable toxic profiles for elderly patients
Summary
Head and neck squamous cell carcinoma is the sixth most common cancer worldwide [1]. The Global Burden of Disease study estimated 890,000 new cases in 2017, representing 5.3% of all cancer patients [2]. The prognosis of patients with recurrent or metastatic. HNSCC (R/M HNSCC) remains poor, with median overall survival (OS) at around. Patients with R/M HNSCC are a unique subset because they are at increased risk of poor prognosis. Half of patients were newly diagnosed to have head and neck cancer at ages over 60 years, and 70% of these patients died at ages over 70 years [4]. The treatment of elderly patients with R/M HNSCC deserves close attention and multi-disciplinary consensus
