EOD Primary Tumor
Notes
**Note 1:** **Locally advanced, resectable tumor** * Code 500 describes locally advanced, but potentially resectable tumor. **Note 2:** **Locally advanced, unresectable tumor** * Codes 600 and 700 describes locally advanced, technically unresectable tumor.| Code | Description | SS2018 T |
