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.

Radiofrequency ablation (RFA) is an effective, longlasting treatment for small kidney tumors in selected patients

Massachusetts General Hospital (MGH) researchers have shown that radiofrequency ablation (RFA) - a minimally invasive way of destroying tissue - is an effective, longlasting treatment for small kidney tumors in selected patients.

New complete muscle grown in the lab

A multinational team of researchers has grown new muscle complete with its own network of blood vessels in the laboratory, and implanted the new muscle in a living mouse. The accomplishment is a first for tissue engineering, according to a report in the June 19 issue of Nature Biotechnology.

New genetic test may detect risk of malignant hyperthermia (MH) from anesthesia

A rare but potentially life-threatening inherited condition called malignant hyperthermia (MH) may strike surgical patients who receive common drugs for general anesthesia.

New genetic test may detect risk of rare complication from anesthesia

A rare but potentially life- threatening inherited condition called malignant hyperthermia (MH) may strike surgical patients who receive common drugs for general anesthesia.

Multisequential MRI approach improves heart inflammation diagnosis

A multisequential approach to cardiovascular magnetic resonance scans that highlight different aspects of heart structure and function may offer a better and safer way to identify potentially deadly inflammation of the heart muscle, according to a new study (PDF) in the June 7, 2005, issue of the Journal of the American College of Cardiology.

Simple blood test can quickly identify type of congestive heart failure

A simple blood test can quickly identify what type of congestive heart failure (CHF) a patient has, improving diagnostic accuracy; eliminating the need for extensive diagnostic tests, such as heart muscle biopsy or exploratory surgery; and enabling the patient to be treated sooner, according to a study published in the June 7 Journal of the American College of Cardiology.

First study to examine liver injury in patients with obstructive sleep apnea (OSA)

Many patients with obstructive sleep apnea (OSA) are obese and therefore at risk of having fatty liver, a condition in which fat accumulates in the liver cells. But the link between OSA and liver injury independent of weight has yet to be examined.

Obesity appears to increase the risk of prostate cancer

The obesity study examined the association between body mass index - weight to height ratio - and prostate cancer in 787 men undergoing biopsy due to an elevated tumor marker in the blood or an abnormal physical exam at a Veterans Affairs hospital in California between 1998 and 2002.

Drug used to treat enlarged prostate may improve the accuracy of prostate biopsies

The drug, dutasteride, suppresses blood flow in benign tissue of the prostate, allowing radiologists to better target cancer tissue using Doppler ultrasound, said Elizabeth Ives, MD, a research fellow at Thomas Jefferson University Hospital in Philadelphia and lead author of the study.

Ultrasound-guided percutaneous biopsies are a safe and effective alternative to endoscopic biopsies

In most cases (61%) a diagnosis was possible after two passes with the biopsy needle. There were no major complications. In 14 of the patients, malignancy was diagnosed; eight patients had benign results.

New blood tests for both prostate and colon cancer

Tessera Inc., a Seattle-based biomedical company is, in collaboration with Dr. Robert Getzenberg, Director of the Brady Urological Research Institute at Johns Hopkins University, developing blood tests for both prostate and colon cancer and expects to commence clinical trials on EPCA (Early Prostate Cancer Antigen), its first blood test for prostate cancer, before the end of this year.

Gluten exposure at 4 to 6 months of age lowers risk of celiac disease

Children with gluten exposure from cereal grains at 4 to 6 months of age have a lower risk of celiac disease than children with exposure before or after this time period, according to a study in the May 18 issue of JAMA.

Jefferson researcher’s results show promise for metastatic eye melanoma

But now, by simultaneously revving up the immune system and choking off the tumor’s oxygen supply, oncologists at Jefferson Medical College and the Kimmel Cancer Center at Thomas Jefferson University in Philadelphia may have found a better way to battle this deadly cancer.

Patients with suspicious axillary lymph nodes in their breasts should first undergo ultrasound-guided fine-needle aspiration to avoid unnecessary surgery

Currently, breast cancer patients undergo axillary lymph node dissection for accurate staging and control of the cancer. In many cases, this major procedure can be replaced by sentinel lymph node biopsy, which is a more simple and less invasive surgical procedure, but many still have to undergo axillary dissection after the sentinel lymph node biopsy.

Identifying high-risk prostate cancer means more prudent treatment decisions

While prostate cancer is a very common diagnosis, it is a deadly disease in relatively few men. One in 6 men will develop prostate cancer during his lifetime. However, of these, only one in 10 cases will be life-threatening.

Cancer can be found earlier in high-risk men if more aggressive screening criteria used

Men at high risk of developing prostate cancer should undergo aggressive screening for the disease. That is the recommendation following a Fox Chase Cancer Center study of 520 men at high-risk of developing prostate cancer in which 25 percent were diagnosed with the disease despite having a low PSA. The findings were presented today at the American Society of Clinical Oncology 41st Annual Meeting.

Breast CT may improve on mammography - more gentler, more accurate

A new breast screening technology that may be able to detect tumors earlier than mammography -- without the need for uncomfortable breast compression -- is being tested in patients at the University of California, Davis, Medical Center.

Scalpel-free surgery could reduce risk of HIV and Hepatitis exposure for health care workers in city hospitals

While the incidence of disease from HIV and hepatitis is increasing in the United States, little is known about their prevalence in patients undergoing surgery. Now, researchers have shown that nearly 40 percent of surgeries at The Johns Hopkins Hospital occur in patients who tested positive for a bloodborne germ.

If you eat too much fat, it can go straight to your liver and damage it

In obese people with nonalcoholic fatty liver disease (NAFLD), fat from the diet ends up "stuck" in the liver, where it doesn't belong. It was known that the livers of NAFLD patients accumulated fat, but its origin was unknown.

Breast cancer detector that uses electricity instead of X-rays

A painless, portable device that uses electrical current rather than X-ray to examine breasts for cancer is under study at the Medical College of Georgia.
