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.

Study finds low rate of breast cancer recurrence after nipple-sparing mastectomy

Women with breast cancer who undergo nipple-sparing mastectomy (NSM) have a low rate of cancer returning within the first five years when most recurrences in the breast are diagnosed, findings of a single-center study show.

Lymph node removal may not be needed for all melanoma patients, study finds

Many patients with melanoma need a sentinel-lymph-node biopsy to determine if cancer cells have spread there, but a positive finding doesn't mean all the lymph nodes in the area must be removed, according to new international study.

MGH researchers identify novel mechanism behind resistance to angiogenesis inhibitors

A Massachusetts General Hospital research team has identified a novel mechanism behind resistance to angiogenesis inhibitors - drugs that fight cancer by suppressing the formation of new blood vessels.

Diabetes leads to increase in autonomic and small fiber neuropathy

Autonomic and small fiber neuropathy used to be considered rare conditions. But with approximately 30 million Americans affected by diabetes – one of the main underlying causes for these diseases – it's an emerging problem.

Optical clearing technique reveals fine structure of the heart

A technique borrowed from neuroscience to see through brain tissue is helping scientists to see the fine structure of the heart.

Modified skin biopsy could provide faster and better diagnosis of inherited, fatal nerve disease

Johns Hopkins physicians report success in a small study of a modified skin biopsy that hastens the earlier diagnosis of an inherited and progressively fatal nerve disease and seems to offer a clearer view of the disorder's severity and progression.

Discarding donated kidneys based on biopsy results may be inappropriate, say researchers

Researchers have found that discarding donated kidneys on the basis of biopsy findings may be inappropriate. The findings, which appear in an upcoming issue of the Journal of the American Society of Nephrology, may help address the organ shortage by keeping valuable organs from being thrown away.

Neural network model judges images to predict melanoma with high degree of accuracy

It's a mark on your skin you've never noticed before. It's a spot with irregular borders, or a mole that seems to be changing. Maybe it's a wound that does not heal.

Anti-asthma drug shows blood glucose improvement among some patients with type 2 diabetes

After 12 weeks of taking an anti-asthma drug, a subset of patients with type 2 diabetes showed a clinically significant reduction in blood glucose during a randomized, double blind, placebo-controlled clinical trial, report University of California San Diego School of Medicine and University of Michigan researchers.

Liquid biopsies provide more information about disease course in non-invasive manner

A new study, to be presented at the ESMO 19th World Congress on Gastrointestinal Cancer, shows that so-called "liquid biopsies", blood tests that detect circulating tumour DNA (ctDNA), may not only sound an early alert that a treatment's effect is diminishing, but may also help explain why -sometimes offering clues about what to do next.

Study: Postponing lymph node biopsy after melanoma diagnosis does not affect long-term outcomes

Postponing lymph node biopsy more than 30 days after melanoma diagnosis doesn't adversely impact long-term clinical outcomes, according to new study findings published online as an "article in press" on the Journal of the American College of Surgeons website ahead of print publication.

DNA methylation can provide effective markers for major cancers, study reveals

In a new study, published online in the July 26 issue of PNAS, researchers at University of California San Diego School of Medicine, with colleagues in Xijing Hospital and Sun Yat-sen Cancer Center in China, report that DNA methylation can provide effective markers for at least four major cancers, not only correctly differentiating malignant tissues from normal, but also providing information on prognosis and survival.

Study finds link between upper GI infections and protein implicated in Parkinson’s disease

Acute and chronic infections in a person's upper gastrointestinal tract appear to be linked to Parkinson's disease, say scientists at Georgetown University Medical Center and their collaborators at the National Institutes of Health and other institutions.

New approaches to early detection of Parkinson's disease on the horizon

Detecting Parkinson's disease before non-reversible symptoms occur: New approaches to early detection are meant to ensure just that. They are based on detection of alpha-synuclein in the skin or intestines.

New 10-minute test uses drops of blood or saliva for early detection of cancers

Researchers at Ram Group's Israeli bio-sensor division have developed a new molecular diagnostics test for early detection of cancers that takes just ten minutes and uses just a couple drops of blood or saliva.

Could a blood test predict how cancer spreads in children?

Traditionally, we use biopsies to try to predict how cancer spreads. There are a number of molecular markers that are used, but biopsy is a limited approach. Now, the current trend is to use liquid biopsy, which is basically a blood sample.

Researchers design new system that enables speedy analysis of laparoscopic procedures

Laparoscopy is a surgical technique in which a fiber-optic camera is inserted into a patient's abdominal cavity to provide a video feed that guides the surgeon through a minimally invasive procedure.

New laser imaging 'bowl' could reduce stages involved in spotting breast cancer

In a bid to make the world's first while-you-wait test for breast cancer, European scientists are developing a comfortable hemispherical bowl lined with laser sources and ultrasound detectors with the potential to reduce the stages in spotting the disease into a single appointment.

New guidelines for ultrasound-based risk stratification system to identify thyroid nodules that warrant biopsy

Nodules -- a type of abnormality detected by ultrasound -- are extremely common in the thyroid gland. Up to two-thirds of adults have nodules in this gland, and most are benign or only cause a slow-growing cancer that is no threat to life.

Scientists develop new three-in-one blood test that could transform prostate cancer treatment

Scientists have developed a three-in-one blood test that could transform treatment of advanced prostate cancer through use of precision drugs designed to target mutations in the BRCA genes.
