Question:
Solid Tumor Rules (2018)/Histology--Endometrium: Is the histology for a serous carcinoma, high-grade endometrial primary 8441/3 (serous carcinoma) or 8461/3 (high grade serous carcinoma)? See Discussion.
Discussion:
Path report reads: 7/15/2019 A. Endometrium, curettings: Serous carcinoma, high grade. B. Endometrial polyp, curettings: Serous carcinoma, high grade.
If coded to 8461/3, according to AJCC, this would not be an ideal code (since it is outdated). Also, endometrium is not included in the suggested site codes for 8461/3 according to the 8/22/2018 ICD-O-3 update.
Answer:
Code histology for this endometrial primary to serous carcinoma 8441/3. Capture "high grade" in the grade field as instructed in the grade coding manual.
"High grade serous carcinoma" has specific clinical and histopathologic features found in ovarian tumors.
