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.

New AI system can evaluate endoscopic findings of ulcerative colitis with accuracy

Assessments of patients with ulcerative colitis, which is a type of inflammatory bowel disease, are usually conducted via endoscopy and histology. But now, researchers from Japan have developed a system that may be more accurate than existing methods and may reduce the need for these patients to undergo invasive medical procedures.

AI helps reveal apparent cellular distinctions between black and white cancer patients

Scientists at Case Western Reserve University are using Artificial Intelligence (AI) to reveal apparent cellular distinctions between black and white cancer patients, while also exploring potential racial bias in the rapidly developing field of AI.

Study provides new evidence about optimal way to treat BRCA carriers with breast cancer

Commonly known as the breast cancer genes, the BRCA gene family plays a role in repairing damaged DNA. Inherited mutations in the genes BRCA1 or BRCA2 raise the risk of developing breast, ovarian, prostate and other cancers.

Combined biopsy more likely to detect aggressive prostate cancers than standard biopsy alone

Using a combination of magnetic resonance imaging (MRI) to target and sample suspicious prostate tissue along with a standard prostate biopsy is significantly more likely to detect the most aggressive prostate cancers than standard biopsy alone.

New method maps 3D forces exerted by tiny cell clusters

A team of researchers has developed a new technique to map the three-dimensional forces that clusters of human cells exert on their surrounding environment. The method could potentially help scientists better understand how tissue forms, how wounds heal or how tumors spread.

Researchers detect a novel cause of acquired lipodystrophy

Nonalcoholic fatty liver disease (NAFLD) is mostly diagnosed in overweight and obese people. However, severe forms of NAFLD can also be detected in rare genetic diseases such as lipodystrophy or in patients with HIV, putting them at a high risk for developing liver failure, diabetes and cardiovascular diseases.

New inhalation therapy could relieve lung fibrosis in mice and rats

A new study published in the journal Nature Communications in February 2020 shows that secretions from stem cells in the lung can be utilized to nebulize injured lungs due to several types of lung fibrosis in rats and mice. This could well result in the development of less invasive and more effective therapies for lung fibrosis.

Johns Hopkins researchers make progress in the development of noninvasive urine test for prostate cancer

Researchers at the Johns Hopkins Kimmel Cancer Center have made significant progress toward development of a simple, noninvasive liquid biopsy test that detects prostate cancer from RNA and other specific metabolic chemicals in the urine.

Brain imaging may help predict when liquid biopsy will benefit individual glioblastoma patients

Tracking brain cancer with a blood test instead of a surgical biopsy may greatly improve quality of life for glioblastoma (GBM) patients and provide critical information for their care, but it is not feasible in all cases.

Biomarkers in blood samples can predict clinical response to immunotherapy in metastatic NSCLC

Non-small cell lung cancer patients with higher measures of tumor mutations that show up in a blood test generally have a better clinical response to PD-1-based immunotherapy treatments than patients with a lower measure of mutations.

Aggressive cancers set up a structural framework to keep the immune system at bay

Aggressive colorectal cancers set up an interactive network of checkpoints to keep the immune system at bay, scientists report.

Simple blood test could be used by GPs to aid in earlier brain tumor diagnosis

A new simple blood test for brain tumors that could be used by GPs in primary care is being developed thanks to funding of nearly £500,000 by Cancer Research UK.

New evidence-based clinical guidelines for surgical treatment of thyroid disease

The first set of comprehensive, evidence-based clinical guidelines for surgical treatment of thyroid disease - developed by an expert panel assembled by the American Association of Endocrine Surgeons - was published today by Annals of Surgery.

New label-free microscopic techniques provide better visualization of extracellular vesicles

The Biophotonics Imaging Lab at the Beckman Institute for Advanced Science and Technology has developed imaging techniques that investigate tissues without using any staining or labels.

New biomarkers for diagnosis and prognosis of lung cancer identified

Applying bioinformatics to resolve biological problems. This is the objective of the research group of the University of Malaga "BI4NEXT", which, in one of its latest studies, developed in the Supercomputing and Bioinnovation Center based on biobank samples, has identified new biomarkers for the diagnosis, prognosis and even treatment of lung cancer.

UCLA study finds new way for tracking treatment of rare liver disease in children

UCLA researchers who previously found that intravenous administration of fish oil can treat a rare but potentially deadly form of liver disease in children have now monitored levels of a small molecule at the center of the disorder to track treatment results.

Intratumoral heterogeneity linked to chemotherapy resistance in small-cell lung cancer

Small cell lung cancer accounts for 14% of all lung cancers and is often rapidly resistant to chemotherapy, resulting in poor clinical outcomes.

New molecular 'fishing' technology can find individual molecules in blood

Like finding a needle in a haystack, Liviu Movileanu can find a single molecule in blood. Movileanu, professor at Syracuse University, and recently graduated Ph.D. student Avinash Thakur will present their research on Monday, February 17 at the 64th Annual Meeting of the Biophysical Society in San Diego, California.

Drinking cocoa could relieve peripheral arterial disease

Someday, according to a new study, doctors might prescribe chocolate or cocoa to help patients with peripheral arterial disease to walk easier. The study published in February 2020 in the journal Circulation Research of the American Heart Association (AHA) reports a significant improvement in walking distance in patients following regular cocoa consumption.
