DCIS

Ductal carcinoma in situ of the breast click to access explanations in the original CAP template

There is different protocol for biopsy specimen

Non-essential elements are identified by "+" sign.

Microscopic descriptions:

- Tumor histology and immunohistochemical studies:

- Histologic type (WHO 6e):	Ductal carcinoma in situ (DCIS) Paget disease Encapsulated papillary carcinoma in situ Solid papillary carcinoma in situ Other, specify:
- Sizes (Extent) of DCIS:	Size (mm x mm x mm) : DCIS blocks : Total blocks :
+ Architectural patterns:	Comedo Cribriform Micropapillary Papillary Solid Solid papillary carcinoma in situ Encapsulated papillary carcinoma in situ Paget disease (DCIS involving nipple skin) Other, specify:
- Nuclear grade:	Grade I (low) Grade II (intermediate) Grade III (high) Other (specify): Cannot be determined (explain):
- Necrosis:
+ Microcalcifications:	Not identified Present in DCIS Present in non-neoplastic tissue Other (specify):

Please use the Breast IHC/DISH template for reporting ER and PR.

Specify Prior Biomarkers on Additional Foci of Invasion (if relevant; i.e., if foci differ in histologic type, grade, or biomarker status; specify tumor identifier for each; may repeat up to 10x).

Surgical margins (distance of the closest margin is required): * Please try to measure all relevant margins. There are differences in management between margins that are directly involved, <2 mm and >= 2mm.

- Anterior margin:
- Posterior margin:
- Superior margin:
- Inferior margin:
- Medial margin:
- Lateral margin:
- Other margins (specify):

Regional lymph nodes:

- Number of lymph nodes with isolated tumor cells (0.2 mm or less and < or = 200 cells):
- Size of largest metastatic deposit (mm), specify site:
- Size of largest lymph node involved (mm), specify site:
- Extranodal extension:

Distant Metastasis: Not applicable Not identified Non-regional lymph node(s) (specify): Lung (specify): Liver (specify): Bone (specify): Brain (specify): Other (specify): Cannot be determined:

Pathologic Stage Classification (AJCC 8e):

- TNM Descriptors:	r (recurrent) y (post treatment) m (multiple primary synchronous tumors in a single organ)
- Primary tumor (pT):
- Regional lymph nodes modifier:	sn Sentinel node(s) evaluated (< 6 lymph nodes) f Nodal metastasis confirmed by FNA or biopsy
