Clinical significance of post-chemoradiotherapy 2-[F]FDG PET/CT response in locally advanced nasopharyngeal carcinoma: A real-world study.

Oral Oncol

February 2025

Department of Nuclear Medicine, Sun Yat-Sen University Cancer Center, State Key Laboratory of Oncology in South China, Collaborative Innovation Center of Cancer Medicine, Guangdong Key Laboratory of Nasopharyngeal Carcinoma Diagnosis and Therapy, Guangzhou 510060, China. Electronic address:

Purpose: To investigate the prognostic value of post-chemoradiotherapy 2-[F]FDG PET/CT in locally advanced nasopharyngeal carcinoma (LANPC) and develop an accurate prognostic model based on the 2-[F]FDG PET/CT results.

Methods: 900 LANPC patients who underwent pretreatment and post-chemoradiotherapy 2-[F]FDG PET/CT from May 2014 to August 2022 were included in the study. We divided the patients into two distinct cohorts for the purpose of our study: a training cohort comprising 506 individuals, included from May 2008 to April 2020, and a validation cohort consisting of 394 individuals, included from May 2020 to August 2022.

This case study details a 36-year-old woman who presented with urinary symptoms following a hysterectomy.

Case: Here, we report the case of a 60-year-old woman diagnosed with LAPC through pathological biopsy who subsequently underwent targeted immunotherapy following the failure of a gemcitabine, oxaliplatin, and S-1 (G&S) chemotherapy regimen.

A 65-year-old patient presented with recurrent, locally advanced poorly differentiated thyroid cancer despite 2 neck surgeries, and with newly diagnosed brain and skull base metastases. He was treated with palliative stereotactic radiosurgery to the brain and skull base lesions. Thereafter, as no targetable genetic alteration was identified and antiangiogenic multikinase inhibitors were deemed at high risk of hemorrhagic complications, off-label systemic therapies were considered.
