Biopsy News and Research

RSS

Biopsy is the removal of cells or tissues for examination by a pathologist. The pathologist may study the tissue under a microscope or perform other tests on the cells or tissue. There are many different types of biopsy procedures. The most common types include: (1) incisional biopsy, in which only a sample of tissue is removed; (2) excisional biopsy, in which an entire lump or suspicious area is removed; and (3) needle biopsy, in which a sample of tissue or fluid is removed with a needle. When a wide needle is used, the procedure is called a core biopsy. When a thin needle is used, the procedure is called a fine-needle aspiration biopsy.

Voluntary living liver donors should undergo a careful, but quick, workup

...and their desire for altruism should not be hampered by negativism from the transplant community, say the authors of a new study in the April issue of Liver Transplantation, the official journal of the American Association for the Study of Liver Diseases (AASLD) and the International Liver Transplantation Society (ILTS).

Biopsy may underestimate prostate cancer in overweight men

Obese and overweight men who are diagnosed with prostate cancer by biopsy are more likely than healthy weight men to actually have a more aggressive case of the disease than the biopsy results would indicate, according to a study led by a Duke University Medical Center researcher.

Optical biopsy finds cancers in first tests on human tissue

In its first laboratory tests on human tissue, a light-based probe built by researchers at Duke University's Pratt School of Engineering almost instantly detected the earliest signs of cancer in cells that line internal organs.

Annual computed tomography screening identifies a high proportion of patients with early-stage lung cancer

Lung cancer remains the leading cause of cancer death in both men and women, killing more people than breast, prostate and colon cancers combined, according to the American Cancer Society (ACS). According to the study, the estimated cure rate for lung cancer in the absence of screening is approximately 5 percent, but increases significantly when the cancer is diagnosed and treated at its earliest stage.

New way to identify which men need a second prostate biopsy

A researcher in the Oregon Health & Science University Cancer Institute and Portland Veterans Affairs Medical Center has found a way to identify which men need a second prostate biopsy because they may be harboring life-threatening prostate cancer even though they were given a clean bill of health after their first biopsy.

Researchers discover markers that identify breast cancer subtypes resistant to Herceptin

Using gene chips to profile tumors before treatment, researchers at Harvard and Yale Universities found markers that identified breast cancer subtypes resistant to Herceptin, the primary treatment for HER2-positive breast cancer. They say this advance could help further refine therapy for the 25 to 30 percent of breast cancer patients with this class of tumor.

Injections with "dermal fillers" containing hyaluronic acid may partially restore sun-damaged skin

Injectable skin fillers have become increasingly popular for correcting the lines and wrinkles associated with aging, as well as acne scars and other skin conditions, according to background information in the article.

Link between MRI contrast agent and nephrogenic systemic fibrosis

New research has shown a possible association between a popular magnetic resonance imaging (MRI) contrast agent and the incidence of a rare disease called nephrogenic systemic fibrosis (NSF) in patients with kidney disease, according to an editorial appearing in the March issue of Radiology.

New guidelines for assessing lymphoma response to treatment

The guidelines will provide clinicians worldwide with uniform criteria to compare and interpret clinical trials of lymphoma treatments and should facilitate the development of new therapies.

Testosterone replacement therapy appears to be safe - has little effect on the prostate gland

Preliminary research suggests that testosterone replacement therapy for men with low testosterone levels appears to have little effect on the prostate gland, contrary to some reports that this therapy may be harmful, according to a study in the November 15 issue of JAMA: The Journal of the American Medical Association.
