What is a multicentric tumor?
Multicentric: Having more than one center. A term often applied to tumors. A minority of Wilms tumors are multicentric and appear to represent separate tumors. A multicentric breast cancer involves two or more distinct primary tumors, usually in different quadrants of the breast.
What is multicentric breast disease?
A multicentric breast cancer is a term given to a breast cancer where there are two or more breast cancers separated by normal breast tissue (often taken as 5 cm of separation 4). It is related to but distinct from the term multifocal breast cancer.
Is multifocal breast cancer common?
Multifocal and multicentric breast cancer (MMBC) is common, with a reported incidence of 9–75%. Incidence varies according to the extent of breast tissue sampling, but this wide range of reported incidence also reflects the lack of a standard definition of MMBC.
Is multicentric breast cancer rare?
Breast cancer in which there is more than one tumor, all of which have formed separately from one another. The tumors are likely to be in different quadrants (sections) of the breast. Multicentric breast cancers are rare.
Which is the most aggressive form of breast cancer?
Triple-negative breast cancer (TNBC) is considered an aggressive cancer because it grows quickly, is more likely to have spread at the time it’s found and is more likely to come back after treatment than other types of breast cancer. The outlook is generally not as good as it is for other types of breast cancer.
What is multicentric HCC?
Multicentric occurrence (MO) and intrahepatic metastasis (IM) are characteristic in the development of HCC with chronic liver diseases that are caused by hepatitis B virus (HBV) or hepatitis C virus (HCV)[8-13].
What is multicentric study?
A multi-centric study is a study that is conducted at more than one research or medical center. The benefits of such studies include a large number of subjects from different geographic places and the ability to compare results from all of them.
Which breast CA is multicentric and bilateral?
Multicentric breast cancer is a similar type of cancer. More than one tumor develops, but in different quadrants of the breast. Anywhere from 6 to 60 percent of breast tumors are multifocal or multicentric, depending on how they’re defined and diagnosed. Multifocal tumors can be noninvasive or invasive.
What is the difference between multifocal and multicentric?
The presence of two or more foci of cancer within the same breast quadrant is defined as multifocal, while the presence of two or more foci of cancer in different quadrants of the same breast is defined as multicentric.
What does Multifocality mean?
1 : having more than one focal length multifocal lenses. 2 : arising from or occurring in more than one focus or location multifocal seizures.
What neoadjuvant chemotherapy means?
Neoadjuvant chemotherapy is delivered before surgery with the goal of shrinking a tumor or stopping the spread of cancer to make surgery less invasive and more effective. Adjuvant chemotherapy is administered after surgery to kill any remaining cancer cells with the goal of reducing the chances of recurrence.
