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 Basal, Patierit. CLINICAL HISTORY: Infiltrating ductal cancer by incisional biopsy. GROSS EXAMINATION: A. "Left breast". Received fresh is a 600 gram, 17 x 14 x 4 cm breast with a. 7. x 5 x 2.5 cm axillary tail. There is a 15 x 10 cm skin ellipse with a 4 cm. in diameter areolar and a 1 cm in diameter nipple. 5 cm superior and lateral. to the nipple is a 2.5 cm well-healed scar. On cut section, a 5.5 x 4 x 3.5. cm firm tan-white mass lies deep to the skin incision. Within the mass is a. 1. x 1 x 1 cm hemorrhagic capsule. The mass appears well-circumscribed but. approaches to within 2 mm of the deep margin. No other lesions are noted. BLOCK SUMMARY: A1-A2- nipple. A3- scar and previous biopsy capsule. A4-A5- representative sections of tumor. A6-A7- deep margin. A8- upper inner quadrant. A9- lower inner quadrant. A10- lower outer quadrant. All- upper outer quadrant. A12- six lymph node candidates, proximal third. A13- five lymph node candidates, middle third. A14- five lymph node candidates, distal third. A15- four lymph node candidates, distal third. A16- four lymph node candidates, distal third. B. "Rotter's node". Received fresh is a 1.2 x 0.7 x 0.5 cm firm node which is. bisected and submitted in toto in Block B1. MICROSCOPIC EXAMINATION: The carcinoma is growing as rounded masses composed of nests and trabeculae. of carcinoma. There is extensive necrosis. 10 mitoses per 10 high power fields. are present. The pattern of growth makes it difficult to be certain what is. invasive and what is in-situ with cancerization of the lobules. DIAGNOSIS: A. "LEFT BREAST" (MASTECTOMY). BREAST WITH RESIDUAL INFILTRATING DUCTAL CARCINOMA, NSABP HISTOLOGIC GRADE. 3, NUCLEAR GRADE MODERATELY-DIFFERENTIATED. SIZE IS 5.5 x 4 x 3.5 CM. INCLUDING PRIOR BIOPSY CAVITY. LESS THAN 5% IDENTIFIABLE AS INTRADUCTAL CARCINOMA, SOLID AND COMEDO TYPES. THE CARCINOMA IS WITHIN 1 MM OF THE DEEP MARGIN. NO LYMPHATIC INVASION IS SEEN. BENIGN CHANGES OF THE BREAST INCLUDING APOCRINE METAPLASIA AND DUCT. ECTASIA. NIPPLE WITH NO PATHOLOGIC DIAGNOSIS. 26 LYMPH NODES WITH NO EVIDENCE OF MALIGNANCY. B. "ROTTER'S NODE" (EXCISION) : eBrowser Result for: 1 of 2. ONE LYMPH NODE, POSITIVE FOR CARCINOMA. eBrowser Result for;. 2 of 2.

expanded version (tokens=1050) : 
 Histological Classification: The report indicates that the patient has residual infiltrating ductal carcinoma in the left breast. The subtype of the cancer is Basal.

Grade: The NSABP histologic grade of the cancer is 3, and the nuclear grade is moderately differentiated.

Necrosis: There is extensive necrosis present within the cancerous masses.

Tumor Infiltrating Lymphocytes: No evidence of lymphatic invasion is reported.

Lymphovascular Invasion: No mention of any lymphovascular invasion is made.

Calcification: The report does not mention any calcification.

Receptor Status: There is no information provided about the receptors in the report.

Ancillary Testing Results: No other ancillary testing results are reported.

Overall, the patient has residual Basal infiltrating ductal carcinoma in the left breast, which is moderately differentiated, with extensive necrosis and no lymphatic invasion. The tumor was present within 1mm of the deep margin. Additionally, the report mentions benign changes of the breast including apocrine metaplasia and duct ectasia. There was also one lymph node, positive for carcinoma, identified in the Rotter's node.

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=1202) : 
 The patient has residual infiltrating ductal carcinoma in the left breast, with a subtype of Basal. The NSABP histologic grade is 3, and the nuclear grade is moderately differentiated. Extensive necrosis is present, with no lymphatic invasion. The tumor was observed within 1mm of the deep margin, and one lymph node was found to be positive for carcinoma in Rotter's node. Additionally, benign changes of the breast including apocrine metaplasia and duct ectasia were noted.
