SSF10 Path Stage Group Selection

Description

This table uses SSF10 to determine which Path Stage Group calculation table will be used.

Notes

**Note:** Since both omental and peritoneal gastrointestinal stromal tumors (GIST) are coded with the same ICD-O-3 topography code (C48.1), this Site-Specific Factor must be used to identify the appropriate TNM stage table.
