abstract = {Background: The aim of the study is to analyse 5-year survival and prognostic factors in patients operated due to lung cancer with postoperatively confirmed metastases to N2 group nodes.
Methods: In the years 2007–2015, 1,148 patients with lung cancer were treated surgically. A postoperative histopathological study confirmed N2 feature in 150 patients. One hundred and ten patients, in whom a 5-year survival analysis was possible to perform, were included in such analysis. The patients underwent the following procedures: pneumonectomy, 31 patients; lobectomy, 61; bilobectomy, 10; and wedge resection, 8. All patients were subjected to supplementary treatment after the surgery.
Results: Five-year survival was achieved in 23 patients (21%). The patients’ survival did not depend on the type of surgery, type of tumour, its location or presence of metastases in N1 nodes (P=0.82, P=0.51, P=0.36 and P=0.23, respectively). A statistically significant correlation was observed (P=0.01) between the 5-year survival of a patient and the occurrence of metastases only in one group of lymph nodes of the N2 feature (22 patients, 20%). Involvement of three or more mediastinal nodal groups resulted in survival shorter than 5-year.
Conclusions: (I) In patients with the N2 feature, the type of performed surgery, type of tumour and the occurrence of metastases in the lymph nodes of the lung hilum do not affect 5-year survival; (II) involvement of only one nodal group allows to achieve 5-year survival in 20% of patients; (III) involvement of three and more nodal groups with the N2 feature results in decreased 5-year survival.},
