Remediastinoscopy after neoadjuvant therapy for XXXX .

Despite technical difficulties due to mediastinal @entity82 , remediastinoscopy can be a valuable tool in the restaging of @entity1149 after neoadjuvant therapy. The aim of our study was to evaluate the feasibility, sensitivity and accuracy of remediastinoscopy. From November 1994 to July 2001 we performed a remediastinoscopy in 27 @entity1 after neoadjuvant therapy. Their age ranged from 35 to 80 years (mean 61.9+/-11.9). In all 27 @entity1 it was possible to perform a remediastinoscopy without major technical difficulties and take biopsies of the lymph nodes that were initially invaded by @entity5 . Remediastinoscopy was positive in 11 @entity1 (40.7%) and negative in 16 (59.3%). In the 11 @entity1 with a positive remediastinoscopy a complete resection was not judged possible and therefore, an unnecessary thoracotomy was avoided. In four @entity1 , remediastinoscopy turned out to be false negative. So, in our series, sensitivity was 73%, specificity 100% and accuracy 85%. The positive and negative predictive values were 100 and 75%, respectively. Previous mediastinoscopy is no contra-indication for a repeat one after neoadjuvant therapy. Although sensitivity and accuracy are lower than that of a first mediastinoscopy, remediastinoscopy is useful to select @entity1 for surgical resection after induction therapy.
