Fig 1 Intramediastinal spread of metastasis related to the primary tumor sites. Open circles indicate skip metastasis; closed circles indicate non–skip metastasis. (LLL = left lower lobe; LUL = left upper lobe; RLL = right lower lobe; RML = right middle lobe; RUL = right upper lobe.)

Fig 3 Kaplan-Meier survival plots for 94 non–small cell lung cancer patients with single-level N2 disease subdivided according to skip (n = 50; red lines) or non–skip (n = 44; green lines) status. The difference in survival between the two groups was significant (p = 0.015). The survival curves are combined with lines representing the 90% confidence interval.

Fig 4 Immunohistochemical staining for D2-40 (A). In comparison with consecutive hematoxylin and eosin–stained section (B), D2-40 staining was detected predominantly in lymphatic vessels. No immunostaining was identified in the tumor cells or blood vessels.

Fig 5 Immunohistochemical staining for vascular endothelial growth factor-C. Vascular endothelial growth factor-C antigens were mainly identified in the cytoplasm of tumor cells.
