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.

Neuroscientists discover gene responsible for HDLS

A global team of neuroscientists, led by researchers at Mayo Clinic in Florida, have found the gene responsible for a brain disorder that may be much more common than once believed. In the Dec. 25 online issue of Nature Genetics, the researchers say they identified 14 different mutations in the gene CSF1R that lead to development of hereditary diffuse leukoencephalopathy with spheroids.

CLND may help reduce papillary thyroid cancer recurrence rates

Papillary thyroid cancer accounts for the majority of all thyroid malignancies, which primarily impact women. A new study indicates that routinely removing lymph nodes in the neck in these cancer patients may help prevent the disease from coming back.

Mammography appears to detect women with low-risk breast cancer

As a woman ages, her chances of being diagnosed with a lower-risk breast tumor increase, according to a novel study led by UCSF which found that for women over 50, a substantial number of cancers detected by mammograms have good prognoses.

SonoCiné AWBU effective in detecting small cancers not detectable with mammography

SonoCiné, Inc., the leading innovator of Automated Whole Breast Ultrasound (AWBU) screening systems for early detection of breast cancer announced today the publication of two important scientific papers reporting on the effectiveness of SonoCiné AWBU in detecting small cancers not detectable with digital mammography.

Study unveils mechanisms behind neurological effects of penitrem A

The mould fungus Penicillium crustosum occurs relatively frequently in food and animal fodder stored in temperate conditions. This mould produces powerful neurotoxins, for example penitrem A, which causes symptoms that are difficult to distinguish from those of other neurological diseases.

Metabolomx' colorimetric sensor array can identify subtype of lung cancer

Metabolomx, a diagnostic company focused on the detection of the metabolomics signature of cancer from exhaled breath, today announces publication of results from the first clinical study demonstrating a breath test that can both detect lung cancer and differentiate between types of lung cancer in humans.

Hologic receives FDA approval for Cervista HTA system to detect cervical cancer

Hologic, Inc., a leading developer, manufacturer and supplier of premium diagnostic products, medical imaging systems and surgical products dedicated to serving the healthcare needs of women, announced today that the U.S. Food and Drug Administration (FDA) has approved its Cervista HTA (high throughput automation) system for use with the Company's previously approved Cervista human papillomavirus (HPV) HR test.

Potential breakthrough test would predict breast cancer progression, recurrence

A Queensland University of Technology (QUT) PhD student has developed a potential breakthrough test for predicting the likelihood of the spread or return of breast cancer.

U.S. DoD awards $11M to study two different ways to treat PTSD in war veterans

A team of researchers who have pioneered novel treatments for post-traumatic stress disorder (PTSD) has been awarded an $11 million, four-year grant from the U.S. Department of Defense to investigate the differences between virtual reality and traditional prolonged exposure therapy.

LTCRT participates in GPS study that seeks to personalize cancer care

The Lawson Translational Cancer Research Team (LTCRT) of the Lawson Health Research Institute is one of five groups participating in a new study that seeks to personalize cancer drug treatment.

No change toward more aggressive biopsy follow-up of PSA tests, finds study

After the US Prostate Cancer Prevention Trial found cancer in many men with low levels of prostate specific antigen (PSA), many debated which PSA level should lead to a biopsy recommendation. The US Preventive Screening Task Force (USPSTF) recently concluded, amid considerable controversy, that the evidence does not support recommending PSA screening for men under 75 years old at all, because the risks outweigh the benefits.

Low-volume high-intensity exercise training may help treat type 2 diabetes

Regular exercise has proven benefits in preventing and treating type 2 diabetes, but many patients find it tough to meet the American Diabetes Association guidelines of 150 minutes of moderate to vigorous exercise a week.

HER2 proteins do not predict breast cancer patient's outcome after Herceptin treatment

Precisely quantifying the amount of three different HER growth proteins, along with several other proteins believed linked to breast cancer, did not predict a patient's outcome after treatment for HER2-Positive Breast Cancer with Herceptin, say Mayo Clinic researchers.

PSA testing that combines blood test with other factors can help men avoid prostate biopsies

Prostate cancer screening that combines an adjusted blood test with other factors including the size of the gland, the patient's overall weight and family history, can help up to one-quarter of men avoid biopsies and the risks associated with them, a Beth Israel Deaconess Medical Center-led research team says.

MRI can predict breast cancer prognosis

Quantitative magnetic resonance imaging measures were associated with prognostic tumor markers, demonstrating the potential of magnetic resonance imaging for prediction of disease prognosis and stratification of patients to appropriate therapies, according to preliminary data presented at the 2011 CTRC-AACR San Antonio Breast Cancer Symposium, held Dec. 6-10, 2011.

Lawson researchers exploit hunger hormone to identify prostate cancer

Non-invasive imaging detects prostate cancer earlier than ever before, but can't accurately distinguish between malignant and benign disease. According to Lawson Health Research Institute's Drs. John Lewis and Len Luyt, a new molecular imaging probe could be the answer.

Fatty livers burn more fat, not less

When our livers become loaded with fat, it isn't because they are slacking. A new study of human patients in the December Cell Metabolism shows that fatty livers actually burn more fat, not less. All that "hard work" may be at the root of the organ damage that comes with nonalcoholic fatty liver disease (NAFLD), a condition associated with insulin resistance that affects about one in three in the U.S. population.

Treatments for lymphoma with no side effects

Larry Conrad went in for his annual physical on his 50th birthday. During his exam, his doctor found swollen lymph nodes in his armpits and groin. Conrad had a cough and said he'd lost weight because he 'felt full all the time'. His doctor ordered a series of tests, and Conrad was diagnosed with Non-Hodgkin's lymphoma, the most common type.

New method reveals complete set of aberrant signaling pathways that give rise to cancers

One major obstacle in the fight against cancer is that anticancer drugs often affect normal cells in addition to tumor cells, resulting in significant side effects. Yet research into development of less harmful treatments geared toward the targeting of specific cancer-causing mechanisms is hampered by lack of knowledge of the molecular pathways that drive cancers in individual patients.

Study reveals no clear advantage of one implant type over another

More than 270,000 Americans get hip replacement surgeries every year -- a number that is projected to double in the next decade as the population ages. With various options for implants, including metal-on-polyethylene, metal-on-metal and ceramic-on-ceramic, there have been questions about which kind works best.
