Abstract

The primary treatment of lung cancer depends on tumor stage. Chest CT scan and bronchoscopy are used to define the TNM stage and resectability. In case of lung cancer without mediastinal lymph node enlargement or direct mediastinal involvement (clinical stage I-IIb + T3N1) surgical treatment is recommended. The use of adjuvant chemotherapy has to be defined, but will be indicated in stage II and IIIa. Expected 5-year survival achieves 40 to 80 % depending on tumor stage. Exceeds the shorter diameter of mediastinal lymph nodes in chest CT scan more than 1 cm (or in case of positive PET scan) mediastinoscopy is indicated. In case of N2-disease and after tumor response to preoperative chemotherapy (about 60 %) secondary resection of the tumor leads to higher 5-year survival rates (20-40 %) compared to patients without induction therapy (5-20 %). In these patients and after unexpected detection of solitary lymph node metastasis by primary resection adjuvant mediastinal radiotherapy should be added. If the tumor has infiltrated the mediastinum or the upper sulcus (T3/4) and/or mediastinal lymph nodes are obviously tumor burden (e. g. > 3 cm, N2 bulky, N3) radical primary resection may not be possible. In these patients combined radi...Continue Reading
