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.

Simple test could help predict best treatment for cystic fibrosis patients

Several cutting-edge treatments have become available in recent years to correct the debilitating chronic lung congestion associated with cystic fibrosis. While the new drugs are life-changing for some patients, they do not work for everyone.

Pioneering research project aims to develop better diagnostic tests for NAFLD

A pioneering European research project aims to lead to new diagnostic tests to assess patients with non-alcoholic fatty liver disease (NAFLD) and identify those most at risk for developing severe inflammation and liver scarring.

Use of Prostate Health Index cuts down need for uncomfortable biopsies

The Prostate Health Index is a cost-effective tool used by urologists to detect prostate cancer. It reduces the risk of over diagnosis, and cuts down on the need to send men for unnecessary and often uncomfortable biopsies.

New technique holds promise to screen cancer cells for drug susceptibility

Doctors have many drugs available to treat multiple myeloma, a type of blood cancer. However, there is no way to predict, by genetic markers or other means, how a patient will respond to a particular drug. This can lead to months of treatment with a drug that isn't working.

Researchers receive £1.3 million to develop sight-saving imaging technology

Staff at the University of Liverpool's Department of Eye & Vision Science have been awarded £1.3 million by the National Institute for Health Research's Intervention for Innovation (i4i) program to develop a state-of-the-art Ultra-Sensitive Optical Coherence Tomography system.

Genetic diversity of tumor tissues can be barrier to precision medicine in gastric and esophageal cancers

A new study focused on describing genetic variations within a primary tumor, differences between the primary and a metastatic branch of that tumor, and additional diversity found in tumor DNA in the blood stream could help physicians make better treatment choices for patients with gastric and esophageal adenocarcinoma.

ATS and JRS publish new guidelines for diagnosis and management of LAM

The American Thoracic Society and the Japanese Respiratory Society have published additional clinical practice guidelines regarding four specific questions related to the diagnosis of lymphangioleiomyomatosis (LAM) and management of pneumothoraces in patients with LAM.

Novel AR glasses help doctors to locate lymph nodes during surgery

Malignant tumors often form metastases that spread to other parts of the body via the lymphatic system. High surgical skills are required to identify the precise location of the affected lymph nodes, enabling them to be completely removed.

Common genetic fusion event could help identify patients with low-risk prostate cancer

Establishing the way in which a genetic alteration called a TMPRSS2-ERG gene fusion forms in a prostate cancer, rather than the presence of the gene fusion itself, could help identify patients with prostate cancer with a low risk of spreading, which might determine the best course of treatment for the patient.

German scientists develop new nuclear medicine test to identify kidney transplant infection

German scientists have developed a novel nuclear medicine test that can determine whether a kidney transplant patient has developed infection in the transplanted tissue.

Study reveals link between circulating tumor cells and relapse in late-stage melanoma patients

A study revealing a connection between circulating tumor cells (CTCs) and relapse in stage IV melanoma patients points to liquid biopsy as a potential predictor of patients at high risk for disease progression. CTCs, tumor cells shed into the bloodstream or lymphatic system, can lead to additional tumor growth and/or metastasis to distant sites.

Gelatin promotes faster healing of the blood brain barrier after injury

Researchers already know that gelatin-covered electrode implants cause less damage to brain tissue than electrodes with no gelatin coating. Researchers at the Neuronano Research Centre at Lund University in Sweden have now shown that microglia, the brain's cleansing cells, and the enzymes that the cells use in the cleaning process, change in the presence of gelatin.

Newly developed tool to analyze synovial tissue may lead to better rheumatoid arthritis therapies

A newly developed tool to analyze the cellular and molecular profiles of synovial tissue and peripheral blood may help unlock clues about rheumatoid arthritis and lead to better therapies, according to new research findings presented this week at the 2017 ACR/ARHP Annual Meeting in San Diego.

Excess weight linked to higher degree of synovitis in RA patients

Excess weight is linked to a higher degree of synovitis in people with rheumatoid arthritis and can affect their treatment response, according to new research findings presented this week at the 2017 ACR/ARHP Annual Meeting in San Diego.

Research reveals presence of potential autoantigen in patients with aggressive kidney disease

New research reveals the presence of abundant levels of a certain protein in the kidneys of patients with fibrillary glomerulonephritis (FGN). In FGN, large amounts of protein become trapped in the millions of filtering units-;or glomeruli-;that make up the kidney.

First-of-its-kind nonsynthetic, decellularized graft one step closer to clinical trials

Researchers at the University of Minnesota have created a new lab-grown blood vessel replacement that is composed completely of biological materials, but surprisingly doesn't contain any living cells at implantation. The vessel, that could be used as an "off the shelf" graft for kidney dialysis patients, performed well in a recent study with nonhuman primates.

Surveillance rather than surgery can be safe option for women with FEA lesions

The detection of certain non-cancerous "high risk" breast lesions can lead to surgical treatment in women, but one of the largest studies of a specific type of high-risk lesion, flat epithelial atypia (FEA), calls for close observation, rather than surgical removal of these lesions in most cases, according to study results published on the web site of the Journal of the American College of Surgeons in advance of print.

Artificial intelligence to support cancer detection, study says

A novel artificial intelligence powered endoscopic system developed in Japan has been proved to automatically detect colorectal adenomas at the time of colonoscopy.

What men need to know: Prevention, diagnosis, and treatment of prostate cancer

Prostate cancer is the second leading cause of cancer death in men. Next to skin cancers, prostate cancer is the most common cancer diagnosed in American men.

New blood test can reliably detect breast cancer in women with dense and non-dense breast tissue

A new study published in PLOS ONE demonstrates that Videssa® Breast, a multi-protein biomarker blood test for breast cancer, is unaffected by breast density and can reliably rule out breast cancer in women with both dense and non-dense breast tissue. Nearly half of all women in the U.S. have dense breast tissue.
