Global longitudinal assessment of treatment outcomes in recurrent/metastatic nasopharyngeal carcinoma: GLANCE-NPC study.

Aim: Given a lack of standard of care treatment for recurrent/metastatic nasopharyngeal carcinoma (R/M NPC), we assessed treatment patterns and overall survival in the real-world setting. Materials & methods: A retrospective chart review was conducted in patients who initiated first-line systemic therapy in Taiwan and South Korea between January 2012 and June 2013 with follow-up through December 2015. Results: Among 154 R/M NPC patients, all patients in Taiwan (n = 104) had distant metastases, whereas in South Korea (n = 50) 42% had distant metastases. Patients with distant metastases generally received systemic therapy only (71%) for whom median overall survival was 23 months (95% CI: 18-32). Conclusion: Prognosis in R/M NPC with distant metastases remains poor, underscoring the need for more efficacious treatments.

Lay abstract Nasopharyngeal carcinoma is an invasive cancer affecting the area behind the nose and above the back of throat. When this cancer returns or spreads to another part of the body, patients receive chemotherapy options with the goal of prolonging survival. To understand chemotherapy approaches used in everyday practice and their effectiveness, we conducted a review of medical records in Taiwan and South Korea. We studied 154 patients who started a first chemotherapy between January 2012 and June 2013 and followed patients through December 2015. Patients whose cancer spread in another part of their body generally received chemotherapy without radiation and lived 23 months on average. Our findings show that more effective treatments must be developed to help prolong survival.

Global treatment patterns and outcomes among patients with recurrent and/or metastatic head and neck squamous cell carcinoma: Results of the GLANCE H&N study.

OBJECTIVES: Given a lack of universally-accepted standard-of-care treatment for patients with recurrent/metastatic head and neck squamous cell carcinoma (R/M HNSCC), study objectives were to assess treatment utilization and survival outcomes for R/M HNSCC in the real-world setting. MATERIALS AND METHODS: A multi-site retrospective chart review was conducted in Europe (Germany, United Kingdom, Italy, Spain), Asia Pacific (Australia, South Korea, Taiwan), and Latin/North America (Brazil and Canada) to identify patients who initiated first-line systemic therapy for R/M HNSCC between January 2011 and December 2013. Patients were followed through December 2015 to collect clinical characteristics, treatment and survival data. RESULTS: Among 733 R/M HNSCC patients across 71 sites, median age was 60 years (inter-quartile range 54-67), 84% male, and 70% Eastern Cooperative Oncology Group performance status 0-1; 32% had oral cavity and 30% oropharyngeal cancers. The most common first-line regimen across all countries consisted of platinum-based combinations (73%), including platinum + 5-fluorouracil (5-FU) (26%), cetuximab + platinum ± 5-FU (22%), or taxane + platinum ± 5-FU (16%). However, use of different platinum-based combinations varied substantially; administration of cetuximab + platinum ± 5-FU was frequent in Italy (81%), Germany (46%) and Spain (38%), whereas use in other countries was limited. Median follow-up was 22.6 months (95% confidence interval [CI]: 21.5-24.6 months). Median real-world overall survival was only 8.0 months (95% CI: 7.0-8.0), with one-year survival reaching only 30.9% (95% CI: 27.5-34.3). CONCLUSION: Systemic therapies used in clinical practice for patients with R/M HNSCC vary substantially across countries. Prognosis remains poor in this patient population, highlighting the need for newer, more efficacious treatments.
