In 169 patients with lung cancer the usefulness of physical examination and Daniel's biopsy in detection of metastases to supraclavicular and scalene lymph nodes were evaluated. In 35 patients with palpable lymph nodes and in 25 patients with nonpalpable lymph nodes metastases were confirmed by histological examination. The sensitivity, the specificity and the likelihood ratio of physical examination in detection lymph nodes metastases were respectively: 58%, 86% and 4.1. In 6 patients (5%) among 119 with nonpalpable lymph nodes the positive Daniel's biopsy was the diagnostic procedure. In 5 patients with non-small carcinoma and in 3 patients with malignant mesothelioma positive results of Daniel's biopsy enabled a change of cancer staging and giving up the eventual surgical operation.
