Comedocarcinoma is a kind of breast cancer that demonstrates comedonecrosis, which is the central necrosis [1] of cancer cells within involved ducts. Comedocarcinomas are usually non-infiltrating and intraductal tumors, characterized as a comedo-type, high-grade ductal carcinoma in situ (DCIS).
DCIS has been classified according to the architectural pattern of the cells (solid, cribriform, papillary, and micropapillary), tumor grade (high, intermediate, and low grade), or the presence or absence of comedo histology; [8] or, in the case of the apocrine cell-based in situ carcinoma, apocrine ductal carcinoma in situ, it may be ...
The sum of these grades is a number between 3 and 9. The score is called a Bloom Richardson Grade (BR) and is expressed [sum of the grades]/9. For example, cells that were graded 2 on all three parameters would result in a BR score of 6/9. A score of 5 and under is considered low. 6 to 7 is considered intermediate. 8 to 9 is considered high. [26]
Papillary carcinomas of the breast (PCB), also termed malignant papillary carcinomas of the breast, are rare forms of the breast cancers. [1] The World Health Organization (2019) classified papillary neoplasms (i.e. benign or cancerous tumors) of the breast into 5 types: intraductal papilloma, papillary ductal carcinoma in situ (PDCIS), encapsulated papillary carcinoma (EPC), solid-papillary ...
Last August, she revealed her diagnosis on her podcast, explaining that she “was diagnosed with high-grade DCIS with micro-invasion.” According to Breastcancer.org , DCIS “is breast cancer ...
G (1–4): the grade of the cancer cells (i.e. they are "low grade" if they appear similar to normal cells, and "high grade" if they appear poorly differentiated) S (0–3): elevation of serum tumor markers; R (0–2): the completeness of the operation (resection-boundaries free of cancer cells or not) Pn (0–1): invasion into adjunct nerves
