[Comment] Retraction and republication—De-escalation of adjuvant radiotherapy in HPV-associated oropharyngeal cancer

In September, 2025, The Lancet Oncology published results of the phase 3 MC1675 study on de-escalated adjuvant radiotherapy versus standard adjuvant treatment for human papillomavirus-associated oropharyngeal squamous cell carcinoma.1 After publication, the corresponding author alerted us to numerical errors present in table 1 caused by a mistranscription of the number of patients in each category of nodal staging by AJCC 7th edition staging and AJCC 8th edition staging. These errors did not affect other data, findings, or interpretation in the paper and we have thus corrected the online version as of Dec 22, 2025.
