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.

Surgeons use patients' own stem cells to rebuild damaged corneas

Surgeons at Massachusetts Eye and Ear have replaced the ocular surface of four patients who each experienced chemical burns to one eye by using their own stem cells taken from the other healthy eye, in a technique known as "cultivated autologous limbal epithelial cell transplantation" (CALEC).

Vaping-related lung injuries have suggestive patterns on CT scans

Injuries to the lungs from vaping have suggestive patterns on CT scans that could help physicians make accurate diagnoses and reduce unnecessary biopsies, according to a new study published in the journal Radiology: Cardiothoracic Imaging.

Researchers identify how promising therapy may work to improve adverse effects of NAFLD

A team led by researchers at Massachusetts General Hospital (MGH) has taken an important step forward in the goal of developing a potential treatment for non-alcoholic fatty liver disease (NAFLD), the most common form of chronic liver disease.

Study highlights the need to standardize training around evaluating urine sediment tests

A new study shows that nephrologists do not always agree on their interpretation of images from urine sediment tests, which are frequently ordered to evaluate a variety of kidney diseases.

Cells lining the nose are key entry point for coronavirus, shows study

Scientists at Johns Hopkins Medicine, experimenting with a small number of human cell samples, report that the "hook" of cells used by SARS-CoV-2 to latch onto and infect cells is up to 700 times more prevalent in the olfactory supporting cells lining the inside of the upper part of the nose than in the lining cells of the rest of the nose and windpipe that leads to the lungs.

ARDS may not be the primary lung iInjury in COVID-19

A new Italian study published on the preprint server medRxiv in August 2020 shows that this may not be an adequate explanation, since ARDS is a nonspecific diagnosis. Instead, they say, antemortem lung biopsy shows a “Covid pattern” of acute lung injury, which could guide the application of therapeutics.

Tiny packages of materials released by tumors may serve as biomarkers for detecting cancers

Because cancer is easier to successfully treat when it's caught early, a major goal in cancer research is to develop new ways to find tumors at early stages, before they start to spread.

Developing a blood test for prostate cancer

Professor Pockley among researchers from the John van Geest Cancer Research Centre have recently developed a blood test for the detection of prostate cancer.

First clinical trial could become an effective way to deliver chemotherapy to abdominal cancer patients

City of Hope surgical researchers are the first in the nation to open a clinical trial that could one day become an effective way to deliver chemotherapy to abdominal cancer patients who currently have very few treatment options.

Researchers identify a useful biomarker for intestinal diseases

Enzymes used by bacteria to break down mucus in the gut could provide a useful biomarker for intestinal diseases, according to new research published in Nature Communications.

FDA approves first companion diagnostic that uses liquid biopsy and NGS technology

Today, the U.S. Food and Drug Administration approved the first liquid biopsy companion diagnostic that also uses next-generation sequencing (NGS) technology to identify patients with specific types of mutations of the epidermal growth factor receptor (EGFR) gene in a deadly form of metastatic non-small cell lung cancer (NSCLC).

Researchers use patient-specific tumor organoid to optimize chemotherapy for appendix, colon tumors

A patient-specific tumor organoid model is being used to identify the most effective chemotherapy protocol to treat appendix and colon tumors, a personalized medicine approach that is showing promise.

A new method to diagnose brain tumors without any incisions

Brain tumors are typically diagnosed using MRI imaging, as taking a sample for a tissue biopsy is risky and may not be possible due to tumor location or a patient's poor health conditions.

Novel technology tests the presence of thin membrane protrusions on breast cancer cells

Researchers at the University of Maryland School of Medicine (UMSOM) have developed a novel technology to test for the presence of thin membrane protrusions called "microtentacles" on breast cancer cells, which can help predict whether a tumor is likely to spread.
