Article Synopsis
- - The study examined the real-world effects of stereotactic body radiotherapy (SBRT) in patients with stage I non-small cell lung cancer (NSCLC), focusing on acute toxicity and 90-day mortality rates among 7,279 patients treated between 2017 and 2021.
- - Acute toxicity occurred in 3.8% of patients, while 90-day mortality was at 1.7%, with certain factors like age, sex, and lung function impacting these outcomes.
- - The findings suggest that SBRT has a low rate of acute toxicity and acceptable mortality, with developed prediction models aiding in identifying patients at higher risk for adverse effects.

Purpose: To determine the influence of PTV-margin (0 mm versus 2 mm) on the incidence of pseudoprogression (PP) and local tumour control (LC) in patients treated with stereotactic radiotherapy (SRT) for solitary brain metastases.
Methods: Patients were treated on Novalis LINAC. Three dose schedules were used depending on the PTV-size.
Purpose: The study compared interobserver variation in the delineation of the primary tumour (GTVp) and lymph nodes (GTVln) between three different 4DCT reconstruction types; Maximum Intensity Projection (MIP), Mid-Ventilation (Mid-V) and Mid-Position (Mid-P).
Material And Methods: Seven radiation oncologists delineated the GTVp and GTVln on the MIP, Mid-V and Mid-P 4DCT image reconstructions of 10 lung cancer patients. The volumes, the mean standard deviation (SD) and distribution of SD (SD/area) over the median surface contour were compared for different tumour regions.
