Hot-spot SBRT vs standard SBRT for early-stage NSCLC
Official title: (PRESTO) A Randomized Phase II Trial Evaluating Hotspots in Stereotactic Ablative Radiotherapy for Early-Stage Non-Small Cell Lung Cancer
Run by Roswell Park Cancer Institute · NCT07718672 · Data updated 2026-11-12
This trial tests whether adding intentional high-dose hot spots to SBRT improves tumor control in people with early-stage non-small cell lung cancer.

Is this trial a fit for you?
✓Likely a good fit
Adults (≥18) with biopsy-proven T1-3N0 NSCLC suitable for SABR, including those with multiple primary lesions under certain conditions.
✕Probably not a fit
Patients with larger or more advanced disease, worse performance status, or intolerance to SBRT may not benefit.

What this trial studies
This phase 2 study compares two SBRT approaches for early-stage NSCLC: SBRT with hotspot planning versus standard SBRT without hotspot emphasis. Primary goal is to see if hotspot planning improves local tumor control. Secondary goals include effects on progression-free survival, overall survival, toxicity, quality of life, and exploratory immune and biomarker changes. The trial also looks at how tumor size and beta-blocker use may influence outcomes and interactions with patient-reported stress and QoL measures.
Why it matters
Potential benefit: If successful, patients could experience better tumor control and possibly longer survival with acceptable toxicity.
How similar studies have gone: Prior SBRT approaches have shown benefit in early-stage NSCLC, but hotspot-based planning is a newer approach with limited clinical precedent.

Inclusion Criteria: * Age ≥ 18 years * Have an Eastern Cooperative Oncology Group (ECOG) performance status of ≤ 2 * Diagnosed with T1-3N0 biopsy-proven NSCLC of the lung. Multiple primary lung tumors are allowed; however, each lesion requires histologic confirmation * Metachronous lung tumors as defined as a new lung lesion in the setting of a historically treated lung cancer are allowed under certain conditions. The previous lung cancer must have been treated greater than 6 months prior to protocol therapy and this cancer must be considered controlled * Eligible for SABR * Participants of child-bearing potential must agree to use adequate contraceptive methods (e.g., hormonal or barrier method of birth control; abstinence) prior to study entry. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately * Participant must understand the investigational nature of this study and sign an Independent Ethics Committee/Institutional Review Board approved written informed consent form prior to receiving any study related procedure Exclusion Criteria: * Patients with a history of a prior lung cancer will be excluded only if the previous treatment is within 6 months of the protocol therapy * Mixed small cell and non-small cell lung cancer * History of allogeneic organ transplantation * History of primary immunodeficiency * Patients must not have undergone prior radiation to overlapping regions of the chest that, in the opinion of the treatment physician, will interfere with protocol treatment * Active autoimmune disease that has required systemic treatment in the last 2 years. Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency) is not considered a form of systemic treatment and is allowed * Known EGFR or ALK mutation * Past medical history of interstitial lung disease (ILD), drug-induced ILD, radiation pneumonitis which required steroid treatment, or any evidence of clinically active ILD * Pregnant or nursing female participant * Unwilling or unable to follow protocol requirements
