Inclusion Criteria:

1. Patients must have FDG-avid and histologically or cytologically proven non-small cell lung cancer.
2. Age 1 8-75.
3. Zubrod performance status 0-2.
4. Stage III ( American Joint Committee on Cancer AJCC, 7th ed.).
5. No prior radiation to the thorax that would overlap with the current treatment field.
6. Adequate bone marrow, renal and hepatic functions as assessed by the following: Hemoglobin \>/= 10.0 g/dl, Platelet count \>/= 1 00,000/mm\^3,absolute granulocyte count (AGC) ≥2 × 10\^9 cells/L,bilirubin and Aspartate transaminase ≤1.5 ×upper limit of normal (ULN), Creatinine \</=1 .5 times ULN.
7. A signed informed consent must be obtained prior to therapy.

Exclusion Criteria:

1. Patients with any component of small cell lung carcinoma are excluded from this study.
2. Patients with evidence of a malignant pleural or pericardial effusion are excluded.
3. Prior radiotherapy that would overlap the radiation fields.
4. Uncontrolled concurrent illness including, but not limited to: Chronic Obstructive Pulmonary Disease(COPD) exacerbation or other respiratory illness, serious uncontrolled infection, symptomatic congestive heart failure (CHF),unstable angina pectoris, uncontrolled hypertension,or psychiatric illness/social situations that would limit compliance with the study requirements.
5. Known hypersensitivity to paclitaxel.
6. Any other condition or circumstance that would, in the opinion of the Investigator, make the patient unsuitable for participation in the study.
