prompt2 : The report is - Final Surgical Pathology Report. Procedure: Diagnosis. A. Sentinel lymph node, left axilla, biopsy: A single lymph node is. negative for malignancy. B. Breast, left, excisional biopsy: Invasive lobular carcinoma,. Nottingham grade 2. Note: The margins are negative for malignancy. C. Breast, posterior lateral margin, biopsy: Focal lobular carcinoma. in situ, negative for invasive carcinoma. Microscopic Description: A. A single lymph node is negative for malignancy. [At the request of some staff oncologists and in keeping with the. opinion of some experts in breast pathology, immunohistochemical stains. for keratin were not used on the sentinel lymph node sections in this. case. These stains can be obtained if desired. Our paraffin blocks. are retained for 10 years. (Weaver DL et al. New Engl J Med 364:412,. 2011. Schwartz GF et al. Cancer 94(10):2542,. B.

expanded version (tokens=1192) : 
 Based on the information in the report, here are the main points:

- The patient underwent a surgical procedure for a breast biopsy and sentinel lymph node biopsy in the left axilla.
- The sentinel lymph node was negative for malignancy.
- The breast biopsy revealed invasive lobular carcinoma, Nottingham grade 2, with a tumor size of 1.7 cm and no evidence of vessel invasion or calcification.
- A focal lobular carcinoma in situ was also present in the posterior lateral margin biopsy.
- The margins were negative for malignancy.
- The tumor had a low mitotic index (0 mitoses/10 HPFs) and was positive for CK5/6 and E-cadherin.
- No lymphovascular invasion was mentioned.
- No receptor status information was provided in the report but it notes that these markers are available if needed.
- Ancillary testing included immunohistochemical stains, which were not used on the sentinel lymph node sections but were used to reveal negative E-cadherin status in the lobular carcinoma in situ tissue.
- Information on any tumor infiltrating lymphocytes was not provided.
- The report includes gross descriptions and specimen details for each biopsy.

final output (tokens=1352) : 
 Patient underwent surgical biopsy of left breast and sentinel lymph node in axilla. The sentinel lymph node was negative, while the breast biopsy showed invasive lobular carcinoma (Nottingham grade 2) with a tumor size of 1.7 cm, negative for vessel invasion and calcification. Lobular carcinoma in situ was present in posterior lateral margin biopsy. The margins were uninvolved. The tumor had a low mitotic index and positive CK5/6 and E-cadherin markers. No information on receptor status or lymphovascular invasion was provided.
