Grade-Breast: How is this field coded for a breast tumor described as "intermediate nuclear grade"? See Discussion.
Guidelines for selecting grade for breast primaries prioritize nuclear grade right after B&R grade. The conversion table displays only numeric values for nuclear grade. How is grade coded for tumors in which nuclear grade is described by terminology? Does it make a difference if the tumor is invasive or in situ?
Example 1: Ductal carcinoma, intermediate nuclear grade.
Example 2: Ductal carcinoma, high nuclear grade.
Example 3: Ductal carcinoma, moderate nuclear grade.
Example 4: DCIS, intermediate nuclear grade.
Use the table on page C-607 of the 2007 SEER manual. The terms "low," "intermediate," and "high" appear in the column labeled "BR Grade." Use this column to determine the appropriate grade code when grade is described using these terms. If the grade of an in situ tumor is described using these terms, use the table to determine the appropriate code for the grade field.
