Abstract: Current studies show that postoperative adjuvant radiotherapy (PORT) may improve local control and overall survival for ⅢAN2 NSCLC. With modern radiotherapy technology and techniques, the adverse effect of PORT is moderate and tolerated. Besides, modern PORT doesn′t decrease the survival. Investigation concerning postoperative target volume for PORT is rare, so that definite agreement has not been reached. Available informations suggest that clinical target volume should include bronchial stump, involved lymph nodes, ipsilateral hilar nodes, subcarinal nodes and ipsilateral lower paratracheal nodes.
