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.

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.

CNIO and HKUST researchers identify how some gliomas acquire chemoresistance

A team led by Massimo Squatrito, Head of the Seve Ballesteros Foundation Brain Tumour Group at the Spanish National Cancer Research Centre, have made important findings of how some gliomas can acquire chemoresistance.

A blood test may be an easy way to predict who will benefit from immunotherapy

A test which detects changing levels of tumour fragments in the blood may be an easy, non-invasive and quick way to predict who will benefit from immunotherapy, a treatment option for advanced cancers.

Avoiding care during the pandemic could mean life or death

These days, Los Angeles acting teacher Deryn Warren balances her pain with her fear. She's a bladder cancer patient who broke her wrist in November. She still needs physical therapy for her wrist, and she's months late for a cancer follow-up.

Researchers report a liquid biopsy for COVID-19

A new study published on the preprint server medRxiv in July 2020 reports the potential of cell-free DNA as a marker of the severity of disease in COVID-19. This could help triage patients as well as provide a prognostic marker.

Aerobic exercise may be more important for improvement in patients with fatty liver diseases

A new study from Trinity College Dublin highlights that fitness may be a more important clinical endpoint for improvement in patients with fatty liver diseases during exercise trials, rather than weight loss.

Deep learning algorithm can identify genetic alterations from routine histological images of tumors

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.

New cancer imaging system hastens cancer detection

A new study highlights a novel imaging system that utilizes near-infrared light, which makes the procedure less invasive and produces faster results.

24 Jul 2020

Novel imaging system can diagnose cancer more efficiently than conventional methods

Cancer diagnosis requires a lengthy process of multiple analyses of tissue biopsies, impeding the quick and early detection of cancers.

Newly identified gene biomarker can distinguish atopic dermatitis and psoriasis with excellent 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. The research will be published online today in the Journal of Allergy and Clinical Immunology.

How to decide whether or not to start treatment for prostate cancer?

You have been diagnosed with prostate cancer and your doctor gives you the option of not being treated, but of remaining under observation: is there any objective way you can decide to be treated or not treated? What should you do?

Rare inherited mutation in TP53 gene confers risk of multiple cancers

Rare inherited mutations in the body's master regulator of the DNA repair system – the TP53 gene – can leave people at a higher risk of developing multiple types of cancer over the course of their lives.
