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.

prompt2 : The report is - Subtype Basal, SPECIMEN. A. Left axillary sentinel node. B. Left breast tissue. CLINICAL NOTES. PRE-OP DIAGNOSIS: Left breast cancer. FROZEN SECTION DIAGNOSIS. A) Lymph node, left axillary sentinel node, excision - One lymph. node negative for metastatic carcinoma (0/1) . GROSS DESCRIPTION. A. Received fresh for frozen section labeled "left. axillary sentinel node" are irregularly-shape fragments. of. fibroadipose tissue that measure 2.5 x 2.2 x 1.2 cm. in dimension. Within the tissue a lymph node is identified that measures 1.6 cm. in maximum dimension. The lymph node is bisected and frozen as AFS1. and AFS2. B. Received fresh in a container labeled "left breast. tissue" is an 8 x 7 x 5 cm. portion of soft tan-yellow. breast tissue partially covered with a 4.5 x 2 cm. tan-pink. wrinkled. skin ellipse. There are orienting sutures present. The specimen. is. inked as follows based upon the orienting sutures: superior -. orange; anterior - blue; posterior - black; inferior - green. The. specimen is sectioned from medial to lateral. On cut surface,. there. is a 2.8 x 2.8 x 2.5 cm. tan white-pink indurated mass, which is. 1.1. cm. from the nearest margin, which is the inferior posterior. margin. The specimen away the mass consists of yellow adipose tissue with. scant interspersed tan tissue. RS-10. BLOCK SUMMARY: B1 - medial margin; B2 - lateral margin; B3,B4 -. tumor to nearest margin (inferior/posterior) ; B5, 6 - tumor to. posterior/deep margin; 7 - superior margin; 8 - skin to tumor; 9,10. - specimen away from mass lesion. GROSS DESCRIPTION. MICROSCOPIC DESCRIPTION. A. Serial H&E stained sections and immunostains with. antibodies to keratin (AE1-AE3) are examined, and the. sentinel lymph node is negative for malignancy. B. The following template summarizes the findings in this. part: Invasive Carcinoma: Present. Histologic type : Invasive ductal carcinoma. Histologic grade: Overall grade: 3. Architectural score: 3. Nuclear score: 3. Mitotic score: 3. Greatest dimension (pT) : 2.8 cm. (pT2). Specimen margins: Negative. Vessel invasion : Not definitively identified. Calcification: There is necrosis within invasive carcinoma which. has focal calcification. Ductal carcinoma in situ: Present focally. Histologic pattern: Solid. Nuclear grade : 3. Central necrosis: Absent. Extensive intraductal component : Absent. Specimen margins: Negative. MICROSCOPIC DESCRIPTION. Description of non-tumorous breast: Changes compatible with. reaction. to prior biopsy. Fibrocystic changes. Prognostic markers: Previously performed (see. 4x2,14,15,20x2. [A few of the antibodies used in our laboratory may be classified. as. analyte specific reagents. These antibodies are monitored and. controlled in our laboratory and their performance for in vitro. diagnosis is well described in the medical literature. They have. not been cleared or approved by the FDA. ]. DIAGNOSIS. A. Lymph node, left axially sentinel, excision -. Negative for malignancy. B. Breast, left, biopsy -. Invasive ductal carcinoma, margins negative for malignancy. (Electronic Signature). --- End Of Report ---.

expanded version (tokens=1184) : 
 Histological classification: The histologic type is invasive ductal carcinoma (IDC), and the subtype is basal.

Necrosis: There is necrosis within invasive carcinoma which has focal calcification.

Tumor infiltrating lymphocytes: The report does not mention any tumor infiltrating lymphocytes.

Histological grade: The overall grade is 3, with an architectural score of 3, nuclear score of 3, and mitotic score of 3.

Nuclear grade: Nuclear grade of invasive carcinoma is 3.

Lymphovascular invasion: The report does not mention lymphovascular invasion.

Calcification: There is necrosis within invasive carcinoma which has focal calcification.

Ancillary testing results: Prognostic markers were previously performed, but the report does not mention the specific results. 

Receptor status: The report does not mention receptor status or IHC results for estrogen receptor, progesterone receptor, or HER2/neu.

In summary, the report mentions that the left breast biopsy showed invasive ductal carcinoma with margins negative for malignancy and an overall grade of 3. There is also necrosis within invasive carcinoma which has focal calcification. The report does not mention lymphovascular invasion or receptor status. Prognostic markers were previously performed, but the specific results are not mentioned in this report.

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=1312) : 
 Left breast biopsy showed invasive ductal carcinoma with margins negative for malignancy and an overall grade of 3. The subtype is basal, and there is necrosis with focal calcification. No tumor infiltrating lymphocytes or lymphovascular invasion are mentioned. Prognostic markers were previously performed, but the report does not specify the results, nor does it mention receptor status or IHC results.
