[Survival and prognostic factors in resected satellite-nodule T4 non-small cell lung cancer].

Objective: To study the survival and prognostic implication in surgically resected satellite-nodule T4 (T4 satellite) non-small cell lung cancer (NSCLC).

Methods: From January 1995 to March 2005, the complete resection was performed to 42 patients with NSCLC who were postoperatively identified as pathologic-stage T4 satellite. Survival and associations between clinicopathological parameters and prognosis were analyzed.

[Impact of different mediastinal lymphadenectomy on clinical-stage IA non-small cell lung cancer].

Objective: To study the role of different lymphadenectomy in the treatment of selected clinical-stage IA non-small cell lung cancer.

Methods: All 115 postoperative patients admitted from January 1997 to May 2002 with pathologic-stage T1 who had been preoperatively diagnosed as clinical-stage I A non-small cell lung cancer were divided into a radical systematic mediastinal lymphadenectomy (LA) group and a mediastinal lymph node sampling (LS) group. Impacts on morbidity, N staging, overall survival (OS) and disease-free survival (DFS) were evaluated in each group respectively.
