The impact of the COVID‐19 pandemic on nasopharyngeal carcinoma extent at FDG PET/MR staging: The NPCOVIPET study

Background To evaluate the impact of coronavirus disease 2019 (COVID‐19) pandemic on disease extent in patients with nasopharyngeal carcinoma (NPC) using 18 fuorodeoxyglucose (FDG) positron emission tomography (PET)/magnetic resonance imaging (MRI). Methods This retrospective cohort study included b...

Description
Summary:Background To evaluate the impact of coronavirus disease 2019 (COVID‐19) pandemic on disease extent in patients with nasopharyngeal carcinoma (NPC) using 18 fuorodeoxyglucose (FDG) positron emission tomography (PET)/magnetic resonance imaging (MRI). Methods This retrospective cohort study included biopsy‐proven, newly diagnosed NPC patients using whole‐body FDG PET/MR staging in two selected intervals: 1 May 2017 to 31 January 2020 (Group A, the pre‐COVID‐19 period), and 1 February 2020 to 30 June 2021 (Group B, the COVID‐19 period). Results Three‐hundred and ninety patients were included. No significant difference was observed in terms of T classification, N classification, overall stage, N stations, and M stations between the two groups (p > 0.05). For the involved neck node levels, more patients had developed level Vc metastasis in the group B (p = 0.044). Conclusion Although the overall stage was not affected, more patients with NPC had developed level Vc metastasis in the era of COVID‐19.
