Abstract

During 10 years from 2004 to 2014 we treat for 94 patients who have NSCLC with N2 were operated in Thong Nhat hospital. Staging was based on AJCC 1997.
Primary outcomes are mortality rate, morbidities. Over all survial, disease freed survival, 5 years survival.
All patients underwent lobectomy or pneumonectomy with lymph node dissection. Adjuvant chemotherapy with platinum based regimen were given for all patients.
78 patients (83,0%) underwent lobectomy, 2 patients (2,1%) underwent bilobectomy, 3 patients (3,2%) underwent pneumonectomy; 3 patients (3,2%) underwent endoscopic lobectomy, 8 patients (8,5%) underwent explorative operation. 62 cases (66,0%) have mediastinal lymph node on CT scan before operation. 42 cases (44,7%) with N2 are positive on histologic findings.*
No mortality, 1 cases had post operation bleeding, 1 case had atelectasia, 2 cases had prolonged air leak.
5 years survival is 19,1%, in group with N2 positive is 14,3% and in group N2 negative is 23,1%
