Randomized Controlled Trial Multicenter Study Comparative StudyLong-term Follow-up on NRG Oncology RTOG 0915 (NCCTG N0927): A Randomized Phase 2 Study Comparing 2 Stereotactic Body Radiation Therapy Schedules for Medically Inoperable Patients With Stage I Peripheral Non-Small Cell Lung Cancer.
To present long-term results of RTOG 0915/NCCTG N0927, a randomized lung stereotactic body radiation therapy trial of 34 Gy in 1 fraction versus 48 Gy in 4 fractions. ⋯ No excess in late-appearing toxicity was seen in either arm. Primary tumor control rates at 5 years were similar by arm. A median survival time of 4 years for each arm suggests similar efficacy, pending any larger studies appropriately powered to detect survival differences.
