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 - Breast, right, simple mastectomy: Infiltrating ductal carcinoma, Nottingham grade III (of III), forming a. well circumscribed mass (4.2 x 4.0 x 3.0 cm) (AJCC pT2) in the lower outer quadrant. Extensive tumor. necrosis is present. There is no associated in situ component. The nipple is uninvolved. The surgical. resection margins are negative for tumor. The closest margin (deep) is free by 0.3 cm. The surrounding. breast tissue shows non-proliferative fibrocystic changes. Lymph nodes, right axillary sentinel Nos. 1A, 1B, IC, and 2, excision: Multiple (4) right axillary sentinel. lymph nodes are negative for tumor. Blue dye is identified in lymph nodes Nos. 1A and 1B. No blue dye. is present in lymph nodes 1C or 2 [AJCC pNO(sn)]. Immunohistochemical cytokeratin stain was. performed on the paraffin embedded sentinel lymph node tissue and confirms the H&E impression. HER2/neu protein overexpression is negative, score of 1+, according to the interpretation guidelines in. the FDA-approved HercepTest. Estrogen: Negative, 0% nuclear staining. Progesterone: Negative, 0% nuclear staining. ER (Estrogen Receptor) test was developed and its performance characteristics determined by. It has not been cleared or approved by the U.S. Food. and Drug Administration.

Overall, this report describes a well-circumscribed mass consistent with infiltrating ductal carcinoma with extensive tumor necrosis. The tumor is negative for estrogen and progesterone receptors and HER2/neu protein overexpression. Sentinel lymph nodes are negative for tumor involvement.

final output (tokens=808) : 
 Report: This is a pathology report for right simple mastectomy. The invasive ductal carcinoma forming a well-circumscribed mass of 4.2 x 4.0 x 3.0 cm, belonging to Nottingham grade III with extensive tumor necrosis, negative sentinel lymph node involvement and no associated in situ components. The tumor is negative for estrogen and progesterone receptors but HER2/neu protein overexpression was negative (score of 1+). All surgical margins were free from the tumor.
