Trends and Efficacy of Definitive Radiotherapy in Elderly Head and Neck Cancer Patients

Strategic Insights -

Elderly patients with locally advanced head and neck squamous cell carcinoma (HNSCC) are increasingly being diagnosed. The effectiveness of definitive radiotherapy (RT) regimens in this age group remains unclear. A large German cancer registry dataset was used to investigate RT regimen trends and their impact on overall survival (OS) and locoregional recurrence (LRR) in elderly HNSCC patients.

Key Takeaways:

  • The number of elderly patients diagnosed with locally advanced HNSCC is rising due to increasing life expectancy.
  • Platinum-based chemotherapy combined with radiotherapy (RCTx) was the most frequently used regimen, but its use decreased in patients aged 70 years.
  • Overall survival (OS) and locoregional recurrence (LRR) rates were analyzed in patients receiving definitive RT alone or combined with chemotherapy (RCTx) or cetuximab (RT-Cet).
  • RT-Cet was associated with poorer outcome particularly in patients aged 70 years, indicating the need for age-adapted, biology-informed treatment strategies.
  • The proportion of elderly patients receiving definitive RT regimens increased significantly over time, from 26% to 57% among younger patients.
  • A retrospective analysis of 84,046 HNSCC cases from 2000 to 2022 was conducted to assess RT administration trends in patients aged 70 years and over.
  • Research was conducted by the German cancer registry group and published in the European Journal of Cancer.

Statistics:

  • 84,046 HNSCC cases from 2000 to 2022 were analyzed in this study.
  • The proportion of elderly patients receiving definitive RT regimens increased significantly over time, from 26% to 57%.
  • OS rate in patients aged 70 years was 2.31 times higher when receiving RT alone compared to RT-Cet.
  • LRR rate in patients aged 70 years was 1.45 times higher when receiving RT-Cet compared to RT alone.
