Inquiry Details
References:
2015 SEER Manual, 95. See Grade for Sarcomas
Question:
Grade/Sarcoma--Breast: Is the correct grade for high grade angiosarcoma of the breast a code 3 or 4? The breast usually uses a three grade system but sarcoma is not a typical histologic type of the breast.
Discussion:
Answer:
Assign grade code 4 using the sarcoma table. Nottingham or Bloom-Richardson (BR) Score/Grade does not apply to angiosarcomas. This is a good question and points out needed clarification of the grade rules.
