final output (tokens=1391) : 
 The surgical pathology report shows that the patient has invasive ductal carcinoma with a histological type of ductal and a subtype of Basal. The tumor is grade 3, with central necrosis in ductal carcinoma in situ and calcification present. No mention is made of tumor-infiltrating lymphocytes. The receptor status is not specified, so further testing may be necessary. The margins are negative for both specimens, and there are no indications of metastasis at this time.
