Popis: Objectives: The purpose of this study was to determine the most suitable candidates for scalene lymph node biopsy to detect non-palpable scalene lymph node metastasis (N3-scalene) in non-small cell lung cancer patients. Methods: Standard cervical mediastioscopies and ipsilateral scalene lymph node biopsies were performed preoperatively by a single surgeon on 121 consecutive patients with non-small cell lung cancer scheduled to have surgical resection between January 1997 and August 2002, who had neither evidence of distant metastasis on imaging diagnosis nor palpable supraclavicular lymph nodes. Results :N 3-scalene was detected in six patients (5.0%), who all had nonsquamous cell carcinoma, including one (1.0%) out of 98 patients with negative standard cervical mediastinoscopy and five (21.7%) out of the remaining 23 patients with positive mediastinal lymph node involvement. There was a significant difference in the incidence of the N3-scalene between the two groups ðP , 0:01Þ: Five patients with N3-scalene had metastatic lesions in the multilevel mediastinal lymph node station on the same side as the cancer (multilevel N2), and accounted for 31.3% of 16 patients with multilevel N2 disease. The N3-scalene was detected in 5 (45.5%) of 11 patients with lung cancer classified as non-squamous cell carcinoma with multilevel N2 disease. Conclusions: The results of the present study suggest that non-palpable scalene lymph node biopsy is indicated for lung cancer patients diagnosed as having non-squamous cell carcinoma with mediastinoscopic multilevel N2 disease. q 2003 Elsevier B.V.
