Patients and Methods
Approval for the study was obtained from the Hospital Ethics Committee.
General Information
In all, 213 cases with stage T1-2N0M0, central-type NSCLC were finally enrolled in the present study. All patients underwent lobectomies, with or without bronchoplastic or angioplastic operations, or both. The mean age was 60.4 ± 10.6 years (range, 12 to 80 years); 183 patients (85.9%) were male and 30 (14.1%) were female. There were 133 (62.4%) squamous cell carcinomas, 39 (18.3%) adenocarcinomas, and 41 (19.3%) other histologic types. Tumor size ranged from 0.5 to 5 cm (mean 3.42 ± 1.19 cm).
Comment
Non-small cell lung cancers of the hilar region are commonly defined as stage I if there is no lymph node metastasis and the tumor diameter is less than 5 cm, regardless of possibly varied resection extent and surgical techniques. For these central-type lung cancers, however, conditions T1/T2 possibly comprise a wide range of disease composites, considering the various kinds of involved hilar structures. Practically, it could also be quite confusing that tumors requiring complicated and
