Different indications for repeat mediastinoscopy: single institution experience of 79 cases.
OBJECTIVE
Different indications exist for repeat mediastinoscopy or remediastinoscopy (reMS). Presently, it is a valuable restaging tool in non-small cell lung cancer (NSCLC). Not only does it provide pathological evidence of mediastinal downstaging, it also selects those patients who will benefit from a subsequent surgical resection and determines prognosis. However, other indications for reMS exist. The authors reviewed their overall experience with reMS.


METHODS
From June 1994 until September 2007, 79 reMS were performed in 75 patients (65 men and 10 women). Mean age was 67.4 years (range 35 to 85 years).


RESULTS
ReMS was performed after induction therapy in 54 cases (68.4%), for recurrent lung cancer in 7 cases (8.9%), metachronous second primary lung cancer in 2 cases (2.5%), for lung cancer occurring after an unrelated disease such as sarcoidosis in 1 case (1.2%), for an inadequate first procedure in 8 cases (10.1%) and for a non-malignant disease such as sarcoidosis or lymphoma in 7 cases (8.9%). ReMS was technically feasible in all patients. There was no mortality. One hemorrhage was encountered from a bronchial artery during reMS which was controlled by packing and one tear in the bronchial wall which was treated conservatively. In patients with lung cancer (71 patients), reMS was positive in 29 cases (40.8%). ReMS provided a definitive diagnosis in 3 patients with sarcoidosis and in one patient with lymphoma .


CONCLUSIONS
Although mostly performed as a restaging procedure after induction therapy in non-small cell lung cancer, reMS can also safely be performed for other indications providing pathological evidence of mediastinal involvement.
