Atypical ductal hyperplasia (ADH) is the term used for a benign lesion of the breast that indicates an increased risk of breast cancer. [1]The name of the entity is descriptive of the lesion; ADH is characterized by cellular proliferation (hyperplasia) within one or two breast ducts and (histomorphologic) architectural abnormalities, i.e. the cells are arranged in an abnormal or atypical way ...
Larger size, nodal spread, and metastasis have a larger stage number and a worse prognosis. The main stages are: Stage 0 which is in situ disease or Paget's disease of the nipple. Stage 0 is a pre-cancerous or marker condition, either ductal carcinoma in situ (DCIS) or lobular carcinoma in situ (LCIS).
The first signs and symptoms may appear if the cancer advances. Because of the lack of early symptoms, DCIS is most often detected at screening mammography. In a few cases, DCIS may cause: A lump or thickening in or near the breast or under the arm; A change in the size or shape of the breast
The Nottingham prognostic index (NPI) is used to determine prognosis following surgery for breast cancer. [1] [2] Its value is calculated using three pathological criteria: the size of the tumour; the number of involved lymph nodes; and the grade of the tumour. [1]
The World Health Organization published the first tumour response criteria in 1981. However the specification documents were unclear which led to criteria adjustments and inconsistent conclusions. In the mid-1990s, an International Working Party was created to simplify and standardize response criteria; it then published RECIST in 2000.
It is important to correctly identify, as it can be confused with atypical ductal hyperplasia, cribriform ductal carcinoma in situ (DCIS), and adenoid cystic carcinoma. [ 1 ] Histomorphologic features
Syndrome of inappropriate antidiuretic hormone secretion (SIADH), also known as the syndrome of inappropriate antidiuresis (SIAD), [2] is characterized by a physiologically inappropriate release of antidiuretic hormone (ADH) either from the posterior pituitary gland, or an ectopic non-pituitary source, such as an ADH-secreting tumor in the lung. [1]
Under current OPTN/ONUS guidelines, patients with cirrhosis and HCC who meet these criteria may be considered for transplantation. [2] Depending on the treatment algorithm, additional factors such as advanced liver disease (as classified by Child-Pugh score ) or evidence of portal hypertension may also affect suitability for transplantation.
