The randomised trial enrolled 40 patients with an indication for curative surgery with or without radiotherapy; the study aimed to improve patients’ clinical prospects through immunotherapy and de-escalate surgery and radiotherapy. Dr Zuur shared the promising results of the immunotherapy, stating 90% of patients who refused surgery displayed disease-free survival of 1 year.
