Long-term Outcomes of Early-stage Nasopharyngeal Carcinoma Patients Treated with Radiotherapy Alone

A retrospective analysis was conducted using systematic records from the Department of Radiation Oncology at our hospital. The study included patients diagnosed with nasopharyngeal carcinoma through endoscopic pathological reports from January 1, 1984, to December 31, 2022. Eligible patients had baseline imaging (CT or MRI) prior to treatment, received definitive radiotherapy at our institution, and were followed up long-term with complete medical records.
