Appendix
Grade Category Calculation Table
- Note:  The Grade Category is based on CS Site-Specific Factor 11, Histopathologic Grading.  The Grade Category is not the same as histologic grade (G); it is an intermediate variable used to derive stage.  Note that the category C2 includes high grade for mucinous tumors and G2 and G3 (moderately differentiated and poorly differentiated) for non-mucinous tumors.
