Aims:
To analyse the outcome of patients with pT1 NSCLC treated at our institution by antero-lateral thoracotomy, anatomical lung resections and mediastinal lymph node dissection between 1980 and 2001.
Methods:
Follow-up data were obtained retrospectively from 1980 to 1990 and prospectively after 1990. Survival was analysed using the Kaplan-Meier method.
Results:
Histopathological examinations revealed mediastinal lymph node infiltration in 27.6% (pN1 17.8% and pN2 9.8%). pN2 was classified in 14.1% of adenocarcinomas compared to 6.2% of squamous cell carcinomas. Median overall survival of patients with pT1 carcinomas was 89+16 months (median+standard error). Histopathological N-classification indicates differential prognostic and therapeutic implications in pT1 adeno- and squamous cell carcinomas.
Conclusions:
Complete lymph node dissection is required for all patients with T1 NSCLC treated by either open surgery or VATS resection. Histopathological N-classification indicates differential prognostic and therapeutic implications in pT1 adeno- and squamous cell carcinomas.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
