Official title
Elimination of PTV Margins Based on Online Adaptive Stereotactic Radiotherapy for Centrally Located Early-stage Non-small Cell Lung Cancer: a Prospective, Single-arm, Phase II Study
Overview
This study aims to explore the safety and efficacy of eliminating the PTV (planning target volume) margins based on online adaptive stereotactic radiotherapy for patients with centrally located early-stage non-small cell lung cancer (NSCLC).
Interventions
- Radiation Online adaptive SBRT
Online adaptive SBRT (without PTV expansion margin). The total dose will be 39-42Gy/3 fractions, administered once daily. FBCT and 4DCT will be acquired.
Primary outcome measures
- Incidence of grade 3 or higher SBRT-related toxicity [Time frame: 1-year]
Secondary outcome measures (3)
- Objective response rate [Time frame: 2 months after radiotherapy]]
- Local control rate [Time frame: 2-year]
- Progression-free survival [Time frame: 2-year]
Eligibility criteria
Inclusion criteria
- Histologically confirmed untreated early-stage non-small cell lung cancer (T1-2N0M0), or recurrent disease (rT1-2N0M0) that is inoperable or where the patient is unwilling to undergo surgery.
- Centrally located lung cancer.
- Age 18 years or older, regardless of gender.
- ECOG performance status score of 0-2.
- Serum hemoglobin ≥ 80 g/L, platelets ≥ 100,000/μL, absolute neutrophil count ≥ 1,500/μL.
- Serum creatinine ≤ 1.25 times the upper normal limit (UNL) or creatinine clearance ≥ 60 ml/min.
- Serum bilirubin ≤ 1.5 times UNL, AST (SGOT) and ALT (SGPT) ≤ 2.5 times UNL, alkaline phosphatase ≤ 5 times UNL.
- FEV1 ≥ 0.5 L.
- Normal CB6 range.
- The patient and their family agree and sign the informed consent form.
Exclusion criteria
- Any other disease or condition that contraindicates radiotherapy (e.g., active infections, within 6 months post-myocardial infarction, symptomatic heart disease including unstable angina, congestive heart failure, or uncontrolled arrhythmias).
- Pregnant or breastfeeding women, women who have not undergone pregnancy testing, and pregnant individuals.
- Individuals with substance abuse issues, chronic alcoholism, or AIDS.
- Individuals with uncontrollable seizures or loss of self-control due to psychiatric disorders.
- Individuals with a history of severe allergies or specific sensitivities.
Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
