Use of [¹⁸F]Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography after Curative Treatment of Non-Small-Cell Lung Cancer Patients: A Nationwide Cohort Study.

ABSTRACT: [¹⁸F]Fluorodeoxyglucose positron emission tomography/computed tomography ([¹⁸F]FDG PET/CT) is a valuable imaging tool in the post-treatment management of non-small-cell lung cancer (NSCLC). This study aimed to investigate the trends in utilization and factors associated with the use of [¹⁸F]FDG PET/CT after curative-intent treatment. Data from 13,758 NSCLC patients diagnosed between 2007 and 2020 identified in the Danish Lung Cancer Registry, who underwent curative-intent treatment, were analyzed using multivariable regression. The results showed a significant increase in the use of [¹⁸F]FDG PET/CT scans, from 10.4 per 100 patients per year in 2007 to 39.6 in 2013, followed by a period of stability. Higher utilization rates were observed in patients who received radiotherapy (22% increase compared to surgical resection) and in patients with stage II-III disease (14% and 20% increase compared to stage I, respectively). Additionally, utilization was increased when other diagnostic procedures were performed, such as MRI, ultrasound, endoscopy, and biopsy. These findings highlight an increasing reliance on [¹⁸F]FDG PET/CT in post-treatment NSCLC, especially after radiotherapy and in patients with locally advanced disease, where treatment-induced radiographic changes and an increased risk of recurrence present a significant diagnostic challenge.

Project description:BackgroundTo investigate the current knowledge and attitudes towards [18F]fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/computed tomography (CT) among non-radiologist medical staff in China.MethodsThis cross-sectional study was conducted between November 18, 2022, and December 6, 2022, at the First Affiliated Hospital (Southwest Hospital) of the Army Medical University (Third Military Medical University) among non-radiologist staff (medical, nursing, and others). The questionnaire survey (Cronbach's α = 0.887) included 28 items: 10 on demographics, 11 on knowledge (maximum score of 22), and seven on attitudes (maximum score of 35). The factors influencing knowledge and attitudes were identified using multivariable logistic regression analysis.ResultsThis study analyzed 631 valid questionnaires. The mean knowledge score was 7.16 ± 6.48 (32.55%), indicating poor knowledge. The mean attitude score was 22.859 ± 2.36 (65.29%), indicating positive attitudes. Nursing (OR = 0.301, 95%CI: 0.159-0.571), other occupations (OR = 0.426, 95%CI: 0.200-0.905), departments with high volumes of PET/CT prescriptions (OR = 0.419, 95%CI: 0.269-0.652), radioprotection training (OR = 2.520, 95%CI: 1.576-4.030), underwent (or a relative) a PET/CT (OR = 1.713, 95%CI: 1.063-2.761), and contact with 1-10 (OR = 2.429, 95%CI: 1.627-3.627) or > 10 (OR = 3.575, 95%CI: 1.762-7.252) patients per month were independently associated with higher knowledge scores. Only the knowledge scores (OR = 1.063, 95%CI: 1.032-1.094) were independently associated with higher attitude scores.ConclusionNon-radiologist medical staff members in China have poor knowledge but positive attitudes toward PET/CT. This study identified knowledge areas worth improving in future training interventions. Radioprotection training appears particularly useful in improving the knowledge of PET/CT, which should translate into more favorable attitudes.Trial registrationNot applicable.
