The Mean

Accurate preoperative staging of the mediastinum is important in the treatment of non-small-cell lung cancer. Enlarged mediastinal lymph nodes on chest computed tomography are positive for malignancy on mediastinoscopy in only half of these patients. After negative mediastinoscopy, some positive nodes are found at thoracotomy. The aim of this study was to attempt to remove all lymph nodes accessible by cervical mediastinoscopic lymphadenectomy and reevaluate the same mediastinal stations at thoracotomy for missed lymph nodes. Between 1999 and 2003, 30 patients with operable non-small-cell lung cancer and enlarged mediastinal lymph nodes (>1 cm in diameter on computed tomography) that were negative on cervical mediastinoscopy underwent pulmonary resection with complete lymph node dissection. The total number of lymph nodes dissected in these 30 patients was 329 (143 at mediastinoscopy and 186 at thoracotomy); the mean numbers of nodes dissected were 4.8 at mediastinoscopy and 6.2 at thoracotomy. Ten (6.5%) residual lymph nodes were detected at thoracotomy in mediastinal stations R4, L4, and 7. The low number of missed lymph nodes demonstrates the accuracy of the technique of cervical mediastinoscopic lymphadenectomy.

Small Series

The value of computed tomography (CT) and of 57Co-bleomycin scintigraphy (57Co-BLM) in staging the mediastinal lymph nodes was compared in 28 patients suffering from non-small-cell lung cancer. The results were assessed against the pathological findings obtained during thoracotomy or mediastinoscopy. CT staging of the mediastinum had a sensitivity of 75%, a specificity of 80%, an accuracy of 79%, a positive predictive index of 60% and a negative predictive index of 89%. 57Co-BLM scintigraphic staging had a sensitivity of 43%, a specificity of 94%, an accuracy of 80%, a positive predicitive index of 75% and a negative predictive index of 81 %. In this small series these differences were not statistically significant; it thus appears that CT and 57Co-BLM are of equal value in staging the mediastinum. Mediastinoscopy is not contributory in case of a negative CT or 57Co-BLM. A positive CT or 57Co-BIM, however, indicates the need for histological verification of the mediastinal findings.
