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 machine learning method detects the pH of a cell to identify whether it is cancerous

Cancerous cells differ from healthy cells in various significant ways. This helps identify them as harmful.

Immune cells in cerebrospinal fluid could be biomarkers to predict immunotherapy response

Results from a study led by Joan Seoane, Director of Preclinical and Translational Research co-program at VHIO and ICREA Professor, show that immune cells accessing cerebrospinal fluid faithfully recapitulate the characteristics of cells identified in brain metastasis, and could therefore constitute novel biomarkers of response to immune-based therapies.

Unique proteomics-based technology can help diagnose breast cancer more accurately

Breast cancer could be identified more precisely than existing methods using blood specimens and exclusive proteomics-based technology.

Triple drug combination keeps people with metastatic colon cancer disease free for longer time

Researchers from SWOG Cancer Research Network, a cancer clinical trials group funded by the National Cancer Institute (NCI), part of the National Institutes of Health, have shown that a triple drug combination - of irinotecan, cetuximab, and vemurafenib - is a more powerful tumor fighter and keeps people with metastatic colon cancer disease free for a significantly longer period of time compared with patients treated with irinotecan and cetuximab.

Women who experience food or housing insecurity have greater risk for undiagnosed breast cancer

Women who experience food or housing insecurity may be at risk for undiagnosed breast cancer due to lapses in follow-up appointments, according to research being presented at the annual meeting of the Radiological Society of North America (RSNA).

Unrelated mutations can lead to false positive results in men with advanced prostate cancer

Unrelated mutations, when present in the blood, can lead to false positive results in men with advanced prostate cancer who are undergoing liquid biopsies.

Experimental AI platform predicts best approach to cancer treatment

The U.S. Food and Drug Administration (FDA) has given final approval to only 4% of all cancer therapeutic drugs being developed.

Imaging technique could replace invasive tissue biopsies to determine cancer drug resistance

Imaging techniques could replace the need for invasive tissue biopsies in helping rapidly determine whether cancer treatments are working effectively, according to researchers at the University of Cambridge.

Researchers identify a driver of drug resistance in some cancers

Patients with BRCA1/2 mutations are at higher risk for breast, ovarian and prostate cancers that can be aggressive when they develop - and, in many cases, resistant to lifesaving drugs.

Detection of cancer using different kind of liquid biopsy

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. One approach that's being studied are liquid biopsies.

Triple-negative breast cancer's ecosystem reveals potential therapeutic targets

Researchers from the Garvan Institute of Medical Research have uncovered four new subtypes of cells within triple-negative breast cancer, which contain promising new therapeutic targets for the aggressive disease.

Enzyme in the gut could provide 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.

Researchers develop new method to diagnose brain tumor without 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.

Deep learning algorithm can infer molecular alterations in cancer from histology images

Researchers at the University of Chicago Medicine Comprehensive Cancer Center, working with colleagues in Europe, created a deep learning algorithm that can infer molecular alterations directly from routine histology images across multiple common tumor types.

Gene biomarker can distinguish between atopic dermatitis and psoriasis with 100% accuracy

Mount Sinai researchers have pinpointed a single gene biomarker, nitride oxide synthase 2 (NOS2) that can distinguish atopic dermatitis (AD) and psoriasis with 100 percent accuracy using adhesive tape strips, a non-invasive alternative to skin biopsy.
