INTERVENTION: Experimental group:Cumulative radiotherapy 66 Gy, 2Gy×19f, once/day.;Control group:Cumulative radiotherapy 60 Gy, 2Gy×16f, once/day.; CONDITION: Non‐small cell lung cancer PRIMARY OUTCOME: Tumor SUVmax;hypoxia area;radiotherapy dose; SECONDARY OUTCOME: Tumor volume;Tumor retraction rate; INCLUSION CRITERIA: 1. Pathological examination confirmed non‐small cell lung cancer (NSCLC); 2. Locally advanced NSCLC that is surgically inoperable or the patient refuses surgery; 3. The lesion area indicated by PET is SUVmax >= 2.5; 4. Blood routine, liver, kidney function and heart function are basically normal.
