Nephrocalcinosis, once known as Albright's calcinosis after Fuller Albright, is a term originally used to describe the deposition of poorly soluble calcium salts in the renal parenchyma due to hyperparathyroidism.
Medullary breast carcinoma is a rare type of breast cancer [1] that is characterized as a relatively circumscribed tumor [2] with pushing, rather than infiltrating, margins. It is histologically characterized as poorly differentiated cells with abundant cytoplasm and pleomorphic high grade vesicular nuclei. [ 3 ]
Staging breast cancer is the initial step to help physicians determine the most appropriate course of treatment. As of 2016, guidelines incorporated biologic factors, such as tumor grade, cellular proliferation rate, estrogen and progesterone receptor expression, human epidermal growth factor 2 (HER2) expression, and gene expression profiling into the staging system.
Invasive carcinoma NST accounts for half of all breast cancer diagnoses in women and is the most common type of invasive breast cancer. It is also the most commonly diagnosed form of male breast cancer. Invasive carcinoma NST is classified by its microscopic, molecular, and genetic features.
By conducting a meta-analysis of four large breast cancer trials including nearly 3,000 patients, the researchers have discovered that an abnormality on chromosome 17, called CEP17, is associated with a worse outcome for patients, but also that its presence is a highly significant indicator that the tumor will respond to anthracyclines.
Medullary carcinoma may refer to one of several different tumors of epithelial origin. As the term "medulla" is a generic anatomic descriptor for the mid-layer of various organ tissues, a medullary tumor usually arises from the "mid-layer tissues" of the relevant organ. Medullary carcinoma most commonly refers to: Medullary thyroid cancer
CEA levels may also be raised in gastric carcinoma, pancreatic carcinoma, lung carcinoma, breast carcinoma, and medullary thyroid carcinoma, as well as some non-neoplastic conditions like ulcerative colitis, pancreatitis, cirrhosis, [12] COPD, Crohn's disease, hypothyroidism [13] as well as in smokers.

While it is no longer considered the most efficient all-around chemotherapy, it retains a great importance in the treatment of elderly patients with luminal cancers and may become important for the treatment of estrogen receptor negative androgen receptor positive luminal (GATA3 expressing) breast cancer.
