Objective. Evaluation of the effects of mediastinal lymph node dissection (ND2) on the outcome in octogenarians with primary lung cancer. Methods. The outcome and post-operative complications were retrospectively investigated in 35 octogenarians with lung cancer; 22 underwent standard operation (ND2 group), 13 underwent limited resection (ND0-1 group). Results. Five-year survival rate was 22.2% and 43.8% in ND2 and ND0-1 group, respectively (p<0.05). In cases of pathological stage I, the survival rate was shorter in the ND2 group (30.8%), than in the ND0-1 group (50.0%). Standard operation with dissection of mediastinal nodes increased the incidence of postoperative cardiac complications (p<0.05). Conclusion. It can be concluded that standard lung operation with mediastinal lymph node dissection leads to higher mortality in octogenarians with lung cancer.
