The indications for transcervical mediastinoscopy in patients with small peripheral bronchial carcinoma.
A series of 80 patients with roentgenographic evidence of bronchial carcinomas 3 centimeters or less in size was analyzed as to the incidence of mediastinal lymph node metastases. Forty patients underwent transcervical mediastinoscopy prior to thoracotomy and 40 patients did not. Three patients with large cell undifferentiated carcinoma had mediastinal lymph node metastases which could be detected by transcervical mediastinoscopy. None of the 40 patients who did not undergo mediastinoscopy had palpable evidence of mediastinal lymph node metastases at thoracotomy. The survival rates for the two groups of patients were similar. On the basis of this study, we have concluded that mediastinal exploration is not routinely indicated in patients with peripheral T1, N1, M0 lesions.
