- Patients with contralateral mediastinal and ipsilateral supraclavicular lymphadenopathy were also included.
- The patients should be between 18 and 75 years old without previous thoracic radiotherapy, chemotherapy or biotherapy.
- Karnofsky performance status was ≥ 80.
- Forced expiratory volume at 1 second (FEV1) ≥ 1 L.
- Had measurable or assessable disease.
- Neutrophilic granulocyte ≥ 1.5×109/L, haemoglobin ≥ 100 g/L, platelet count ≥ 100×109/L.
- Serum creatine and bilirubin < 1.5 × the upper normal limit (UNL), aminotransferase < 2 × UNL.
- Weight loss was less than 10% within 6 months before diagnosis.
- Written informed consent was required from all patients.
Exclusion Criteria:
- Patients were ineligible if they had a history of other malignant diseases except for non-melanomatous skin cancer and carcinoma in situ of the cervix, or any contraindications for chemoradiotherapy, malignant pleural and/or pericardial effusion.

control arm
For patients who are randomized to study arm, (i.e. to irradiate the post-chemotherapy tumor extent) the clinical target volume-tumor (CTV-T) includes the post-chemotherapy gross tumor volume-tumor (GTV-T) with a margin of 0.8 cm. Chemotherapy includes etoposide 100mg/m2 d1-d3 combine with cisplatin 80mg/m2 d1 at 21-day interval for 4 cycles. Radiotherapy will be administered with cycle 3 chemotherapy(1.5 Gy twice daily to 45 Gy in 30 fractions over 3 weeks)
