I am sending here generally how we sign out the invasive carcinoma for excision or mastectomy specimens. Below you can see what we describe in our final report. It is not neccesary for you to do the same also. Just for your referecne. I once studied and work in several hospitals in the US. Every one is different in term of the report. However, the priniciples are same.

Breast (Re-)excision/mastectomy for invasive and in situ carcinoma

SECTION A (INVASIVE CA)

-Invasive ductal carcinoma, _________,(no special type, pure mucinous type, pure tubular type etc.) type.

-Invasive ductal carcinoma, mixed __________(__%) and _________(___%) types.

-Invasive lobular carcinoma, classical type, with a solid / alveolar / trabecular growth pattern(s).

-Invasive lobular carcinoma, pleomorphic type.

-Invasive lobular carcinoma, mixed pleomorphic (___%) and classical (_____%) types.

-Invasive mixed ductal and lobular carcinoma.

SECTION B (Grade)

Nottingham Grade I / II / III (tubule formation: _____, nuclear pleomorphism: ________, mitotic activity: _______; total score: ___/9).

SECTION C (Size)

The invasive tumor measures __________cm in largest dimension (give microscopic size if it is a small tumor;  use the gross dimension for large tumor).

SECTION D (In-situ CA)

Ductal carcinoma in situ (DCIS), nuclear grade 1 / 2 / 3, solid / cribriform / papillary / micropapillary / apocrine type(s)

with minimal / moderate / comedo necrosis.

Lobular involvement by DCIS is present.

The DCIS constitutes  ____% of the total tumor mass, and is present admixed with and away from the invasive component / and is present admixed with the invasive component / and is present away from the invasive component.

The DCIS is present in _____ of ______ slides (Give this information in cases of extensive intraductal component).

Lobular carcinoma in situ (LCIS) is also identified, with pagetoid extension into ducts.

SECTION E (Lympho-vascular space Invasion)

Lympho-vascular space invasion is identified.

No lympho-vascular space invasion is noted.

SECTION F (Surgical Margins)

Negative:

Resection margins are negative for carcinoma.

Resection margins are negative for invasive carcinoma.

Resection margins are negative for ductal carcinoma in situ.

Invasive carcinoma is _____cm from the nearest ____________________marigin.

Ductal carcinoma in situ is ______cm from the nearest ____________________marigin.

Pleomorphic lobular carcinoma in situ is _______ cm from the nearest ____________________marigin.

Positive:

Rare / A few / Multiple focus/foci of invasive carcinoma extends to the ____________________ margin(s).

Rare / A few / Multiple foci of ductal carcinoma in situ extends to the _____________________ margin(s).

Rare / A few / Multiple foci of pleomorphic lobular carcinoma in situ extends to the _________________ margin(s).

Do not report the margin for classic lobular carcinoma in situ.

Negative inked margins but tumor <1mm from margin:

Inked margins are negative for carcinoma. However, rare / a few / multiple focus/foci of invasive carcinoma is/are <1mm to the _________________ margin(s).

Inked margins are negative for carcinoma. However, rare / a few / multiple focus/foci of ductal carcinoma in situ is/are <1mm to the _________________ margin(s).
