2 Figure 1 Study design. The flow chart describes the diagnostic procedures used for a mediastinal lymph node analysis of lung cancer patients. To prevent false-negative results, patients with negative endobronchial ultrasound-guided fine-needle aspiration were subjected to mediastinoscopy, and patients with negative mediastinoscopy were treated by surgical resection.

3 Figure 2 Comparison between quantitative melanoma antigens 1–6 and melanoma antigens 12 expression. The relative quantification values of melanoma antigens 1–6 and 12 gene expression were plotted against each other on a logarithmic scale for endobronchial ultrasound-guided fine-needle aspiration samples (A, Spearman's [rho] correlation coefficient, r = 0.422; p < 0.001) and mediastinoscopy samples (B, Spearman's [rho] correlation coefficient r = 0.257; p = 0.004).

4 Figure 3 Mediastinal lymph node metastasis of a squamous carcinoma of the lung. A, Histological specimen showing compact formations of tumor cells (⋆) within a desmoplastic stroma containing few rests of lymphatic tissue (L). Hematoxylin and eosin (HE)staining, 100-fold magnification. B, Cell cluster of an endobronchial ultrasound-guided fine-needle aspiration specimen with a group of tumor cells adjacent to residual lymphocytes of the lymph node. Note intracellular keratinization in one of the tumor cells (⇓). HE staining of the liquid-based cytology, 200-fold magnification.
