Table 4.
Percentage of all involved thoracic lymph node stations in upper vs. lower esophageal cancers. (i.e., cervical nodes represented 5% of the total number of FDG-avid nodal stations in upper thoracic tumors)
| Tumor location | ||
|---|---|---|
| Thoracic nodal stations | Upper thoracic | Lower thoracic/GE junction |
| Cervical | 5 | 1 |
| 1 (Supraclavicular) | 27 | 4 |
| 2 (Upper paratracheal) | 11 | 2 |
| 3A (Prevascular) | 5 | 0 |
| 3P (Retrotracheal) | 17 | 5 |
| 4 (Lower paratracheal) | 13 | 7 |
| 5 (Aortopulmonary window) | 2 | 1 |
| 6 (Para-aortic) | 1 | 1 |
| 7 (Subcarinal) | 5 | 5 |
| 8 (Paraesophageal, below carina) | 6 | 19 |
| 9 (Pulmonary ligament) | 0 | 0 |
| 10, 11 (hilar) | 6 | 5 |
