Early Versus Late Concurrent Chemoradiation for Limited Stage Small-cell Lung Cancer

A Randomized Phase III Trial for Timing of Radiation in Concurrent Chemoradiation for Limited Stage Small-cell Lung Cancer

The purpose of the study is to evaluate the efficacy and toxicity of different timing of concurrent chemoradiation in the treatment of limited disease status Small-cell lung cancer.

Inclusion Criteria:

• histologically confirmed small-cell lung cancer
• limited disease status
• with evaluable disease
• 18 years or older
• ECOG performance status 0,1,2
• expected survival time should be 12 weeks or longer
• Adequate organ function as evidenced by the following; Absolute neutrophil count > 1.5 x 109/L; platelets > 100 x 109/L; total bilirubin ≤1.5 UNL; AST and/or ALT < 5 UNL; creatinine clearance ≥ 50mL/min
• Written informed consent form

Exclusion Criteria:

1. Uncontrolled systemic illness such as DM, CHF, unstable angina, hypertension or arrhythmia
2. Patients with active infection requiring antibiotics
3. Pregnant or nursing women ( Women of reproductive potential have to agree to use an effective contraceptive method)
4. Prior history of malignancy within 5 years from study entry except for a adequately treated basal cell or squamous cell skin cancer or in situ cervical cancer, well-treated thyroid cancer
5. previous history of chemotherapy or radiotherapy
