title: How effective is the routine mediastinal blockdissection in the surgery of non-small cell lung cancer?
abstract: The performance of ipsilateral mediastinal blockdissection as a routine in every non-small cell lung cancer (NSCLC) operation gives us a chance to judge the accuracy of the preoperative CT examination. The accuracy rate of the CT in our 316 cases was 70.6%, the false positive rate was 69.6%, the false negative rate was 18.2%. Taking into account the 18.2% false negative rate and the slightly better survival of patients operated with routine blockdissection compared to the survival of a group of patients who had mediastinal blockdissection only if suspicion of tumour spread arose, we consider the procedure reasonable in every NSCLC operation.
