prompt1 : extract information from  breast pathology report. List the histological classification, i.e. type of cancer or DCIS, subtype, description of any necrosis, any mention of tumor infiltrating lymphocytes,  histological grade, nuclear grade,  lymphovascular invasion, calcification, receptor status, IHC and any other ancillary testing results.  List out and expand the main points.
prompt2 : The report is - Subtype LumA, SPECIMEN. A. Sentinel node left breast. B. Left breast. C. Left sentinel node. CLINICAL NOTES. PRE-OP DIAGNOSIS: Left breast cancer. FROZEN SECTION DIAGNOSIS. A. Benign on frozen section. C. Benign on frozen section. GROSS DESCRIPTION. A. Received fresh in a container labeled "A. sentinel. node. left breast" is a portion of soft to rubbery tissue, 2.6 x. 2 x 0.7 cm. Externally much of the specimen is fatty. On cut. surface, there is some tan-pink lymph node tissue, with prominent. fat replacement. The specimen is entirely submitted for frozen. section in three blocks. B. Received fresh in a container labeled "left breast" is. a 33 x 16 x 3.5 cm mastectomy specimen, partially surfaced. by a 20 x 11 cm tan-pink wrinkled skin ellipse, with a 1.6 cm in. diameter everted nipple. There is no gross lesion on the skin. surface. There is an arrow indicating superior. The deep aspect of. the specimen is inked and the specimen is serially sectioned,. revealing a 3.3 x 3.3 x 2 cm tan-white firm indurated mass which is. 1.3 cm from the deep margin. The mass is located centrally but. slightly laterally, with the closest margin the aforementioned deep. margin, with the tumor not grossly near a margin. The specimen. outside the mass lesion consists of yellow adipose tissue with. interspersed tan-white tissue, without additional focal lesion. No. lymph nodes are identified with the breast. RS-10. GROSS DESCRIPTION. BLOCK SUMMARY: B1,B2 - entire nipple, and skin; B3 - deep margin. deep to tumor; B4-B6 - tumor (sections do not include margin) ; B7. inner upper quadrant; B8 - inner lower quadrant; B9 - outer lower. quadrant; B10 - outer upper quadrant. C. Received fresh in a container labeled "left sentinel. node" is a portion of soft to rubbery tan-yellow tissue, 2. X 1.5 X 0.7 cm. On cut surface, the specimen is predominantly. fatty,. with some identifiable tan-pink lymph node tissue. It is entirely. submitted for frozen section in two blocks. MICROSCOPIC DESCRIPTION. A,C. The lymph nodes are negative for malignancy. In. addition to examining serial H&E stained sections,. immunostains with antibodies to keratin (AE1/AE3) are examined,. without specific staining, supporting the interpretation that the. lymph nodes are negative for malignancy. B. The following template summarizes the findings in this. part: Invasive carcinoma: Present in the mass lesion in the breast in. part. B. Histologic type: Invasive ductal carcinoma. Histologic grade: Overall grade: 1. Architectural score: 2. Nuclear score: 2. Mitotic score: 1. MICROSCOPIC DESCRIPTION. Greatest dimension (pT) : 3.3 cm (pT2). Specimen margins: Negative for tumor. Vessel invasion: Not identified. Calcification Present focally. Nipple: Negative for tumor. Invasion of skin or chest wall: Not identified. Ductal carcinoma in situ: Present very focally, with the vast. majority of the carcinoma in this specimen invasive carcinoma. Histologic pattern: Cribriform. Nuclear grade: 1-2. Central necrosis: Absent. Specimen margins: Negative. Calcification: Not identified within DCIS. Description of non-tumorous breast: Fibrocystic changes. Prognostic markers: Previously performed on a prior specimen at an. outside institution. 4x3,14x2,15x3,20x5. DIAGNOSIS. A,C. Lymph nodes, left sentinel, excisions -. Negative for malignancy. B. Breast, left, excision -. Invasive ductal carcinoma (see microscopic description). Skin, nipple, and margins negative for malignancy. M.D. (Electronic Signature). --- End Of Report ---.

expanded version (tokens=1258) : 
 Histological classification: Invasive ductal carcinoma and ductal carcinoma in situ (Cribriform)

Subtype: LumA

Nuclear grade: 1-2

Lymphovascular invasion: Not identified

Calcification: Present focally

Receptor status: Prognostic markers previously performed on a prior specimen at an outside institution (details not provided)

Tumor infiltrating lymphocytes: Not mentioned

Histologic grade: Overall grade: 1. Architectural score: 2. Nuclear score: 2. Mitotic score: 1.

Ancillary testing results: Immunostains with antibodies to keratin (AE1/AE3) were examined to confirm the absence of malignancy in the lymph nodes

Other details: No invasion of skin or chest wall, margins are negative for tumor, and nipple is negative for tumor. Fibrocystic changes were observed in non-tumorous breast tissue.

Overall, the report confirms the presence of invasive ductal carcinoma and ductal carcinoma in situ, both classified under the LumA subtype. Histologic grading indicates lower grade features. The margins, lymph nodes, and nipple are negative for malignancy. The presence of calcification is noted. Prognostic markers were performed previously on a prior specimen at an outside institution.

prompt : Please generate a succinct report in 75 words from the above information. Exclude any filler words or sentences. If something is not mentioned or specified, exclude it from the report. Low verbosity.

final output (tokens=1405) : 
 Report: Invasive ductal carcinoma and ductal carcinoma in situ (Cribriform) are present. They are classified under the LumA subtype with favorable histologic grade. No invasion of skin or chest wall, and margins are negative for tumor. Lymph nodes and nipple do not show any malignancy. Calcification is present focally. Prognostic markers were performed previously on a prior specimen at an outside institution, and non-tumorous breast shows fibrocystic changes.
