Trial Outcomes & Findings for One Fraction Simulation-Free Treatment With CT-Guided Stereotactic Adaptive Radiotherapy for Patients With Oligometastatic and Primary Lung Tumors (NCT NCT06236516)

NCT ID: NCT06236516

Last Updated: 2026-05-01

Results Overview

Feasibility is defined as the successful completion of the ONE STOP workflow through treatment delivery in at least 70% of patients. Successful completion of the workflow is defined as ONE STOP plan creation and delivery of the fraction using the study workflow in one on-table attempt. Unsuccessful completion of the workflow is defined as multiple attempts of the ONE STOP workflow for one patient without treatment delivery such that the study workflow is abandoned and a traditional one-, three-, or five-fraction plan is delivered.
