Study Arms (1)
The study group
EXPERIMENTALPatients in the study group will receive online adaptive stereotactic body radiotherapy (without PTV expansion margin). The total dose will be 39-42Gy/3fractions, administered once daily. Both FBCT and 4DCT will be acquired before initiating treatment at each fraction.
Interventions
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.
Eligibility Criteria
You may qualify if:
- 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.
You may not qualify if:
- 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.
