PR: Negative Allred Score: 0 = Proportion Score 0 + Intensity Score 0. COMMENT: The Allred score for estrogen and progesterone receptors is calculated by adding the sum of the. proportion score (0 = no staining, 1 = <1% of cells staining, 2 = 1 - 10% of cells staining, 3 = 11-30% of. cells staining, 4 = 31-60% of cells staining, 5 = >60% of cells staining) to the intensity score (1 = weak. intensity of staining, 2 = intermediate intensity of staining, 3 = strong intensity of staining), with a scoring. range from 0 to 8. ER/PR positive is defined as an Allred score of >2 and ER/PR negative is defined as an Allred score. of less than or equal to 2. METHODOLOGY: Tissue was fixed in 10% neutral buffered formalin for no less than 8 and no longer than 24 hours. Immunohistochemistry was performed using the mouse anti-human ER (ER 1D5, 1:100) and PR (PGR. 136, 1:100) provided by. following the manufacturer s instructions. This. assay was not modified. Interpretation of the ER/PR immunohistochemical stain is guided by published. results in the medical literature, information provided by the reagent manufacturer and by internal. review of staining performance. SYNOPTIC REPORT - BREAST HER-2 RESULTS. Specimen: Surgical Excision. Block Number: B44. Interpretation: NEGATIVE. Intensity: 1+. % Tumor Staining: 5%. Fish Ordered: METHODOLOGY: Tissue was fixed in 10% neutral buffered formalin for no less than 8 and no longer than 24 hours. Her2 analysis was performed using the FDA approved Dako HercepTest (TM) test kit. using rabbit anti-human HER2. This assay was not modified. External kit-slides. provided by the manufacturer (cell lines with high, low and negative HER2 protein expression) and in-. house known HER2 amplified control tissue were evaluated along with the test tissue. Adequate, well. preserved, clear-cut invasive carcinoma was identified for HER2 evaluation. Interpretation of the HER2. immunohistochemical stain is guided by published results in the medical literature, information provided. by the reagent manufacturer and by internal review of staining performance. This assay has been validated according to the 2007 joint recommendations and guidelines from. ASCO and CAP and from the NCCN HER2 testing in Breast Cancer Task Force. The Pathology. Department takes full responsibility for this test's performance. CLINICAL HISTORY: year old with left breast ca. PRE-OPERATIVE DIAGNOSIS: Left breast ca.

expanded version (tokens=2578) : 
 The breast pathology report indicates the following:

- Histological classification: Invasive ductal carcinoma with squamous features and necrosis, measuring 9 cm.
- Subtype: Basal.
- Description of any necrosis: Present.
- Any mention of tumor infiltrating lymphocytes: None identified.
- Histological grade: SBR grade 3.
- Nuclear grade: 3.
- Lymphovascular invasion: None identified.
- Calcification: Not mentioned in the report.
- Receptor status: ER negative, PR negative, HER2 negative.
- IHC and any other ancillary testing results: Allred score for estrogen and progesterone receptors is 0 and HER2 score is 1+. Axillary dissection revealed metastases to five of thirty-four lymph nodes with extranodal extension; all additional axillary nodes were negative for metastases. Lobular carcinoma in situ (LCIS) was also identified.

In summary, the report describes a large invasive ductal carcinoma with squamous features and necrosis, classified as basal subtype, with high-grade characteristics and negative hormone receptor and HER2 receptor status. Five out of thirty-four lymph nodes examined were positive for metastases with extranodal extension, and no lymphovascular invasion was identified. LCIS was also noted.

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=2697) : 
 Basal subtype invasive ductal carcinoma with squamous features, nuclear grade 3 and necrosis identified in left breast biopsy. ER negative, PR negative, HER2 negative. Axillary dissection revealed 5 out of 34 lymph nodes positive for metastases with extranodal extension. No lymphovascular invasion identified. LCIS noted in specimen.
