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 tool predicts which cancer patients will respond positively to immunotherapy

An international group led by Dr Banafshe Larijani, an Ikerbasque researcher seconded to the Biofisika Institute (UPV/EHU-University of the Basque Country, CSIC), has developed a new diagnostic method making it possible to accurately predict which cancer patients will respond positively to immunotherapy.

Study could pave the way for potential urine test to diagnose liver fibrosis

Fifty fragments of proteins, termed peptides, have been identified in the urine of liver fibrosis patients in a new study that could pave the way for a potential diagnostic urine test for the condition if further validated.

Ultrasound reveals a possible role of SARS‐CoV‐2 in acute testicular infection

A single-center study from Wuhan in China presents ultrasound imaging evidence supporting the notion that the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can cause infection of the testis or epididymis – and put patients at risk for further complications. The paper can be found in the Journal of Ultrasound in Medicine.

Underrepresented minorities are at increased risk for AL amyloidosis

Despite being theoretically at an increased risk for AL amyloidosis, underrepresented minorities make up only a small percentage of patients seen at specialized treatment centers for this disease.

HSS presents research related to rheumatology and orthopedic surgery at 2020 ACR annual meeting

At this year's American College of Rheumatology virtual meeting, Hospital for Special Surgery (HSS) presented exciting research related to rheumatology and orthopedic surgery.

Active surveillance is a safe and viable option for men with low-risk prostate cancer

Men undergoing active surveillance for prostate cancer have very low rates - one percent or less - of cancer spread (metastases) or death from prostate cancer, according to a recent study published in The Journal of Urology®, an Official Journal of the American Urological Association.

A substantial minority of middle-aged adults have liver fibrosis

A substantial minority of participants from the Framingham Heart Study, (nearly nine percent), had potentially clinically significant liver fibrosis (scarring). This the first study of this size and scale done in the United States.

Study shows SARS-CoV-2 direct heart muscle cell infection, cell death, loss of contractility

In the study, published on the pre-print journal bioRxiv, the researchers revealed that SARS-CoV-2-infected EHTs manifested the typical characteristics of myocarditis or heart inflammation. These include the stimulation of immune cells, heart cell death, and decreased contractile force generation.

Study identifies key clinical features of chronic nonbacterial osteomyelitis

New research presented at ACR Convergence, the American College of Rheumatology's annual meeting, identified key clinical features of chronic nonbacterial osteomyelitis (CNO), which leads to an important step toward the development of much-needed classification criteria for a disease that affects children and young adults worldwide.

Researchers develop novel chemo-immunotherapy agent to treat pancreatic tumors

Pancreatic cancer is highly lethal: according to the National Cancer Institute, only about 10 percent of patients remain alive five years after diagnosis.

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.

Experts release new guidance for endoscopists on how to assess colorectal lesions

Early identification and removal of cancerous colorectal polyps is critical to preventing the progression of colorectal cancer and improving survival rates.

Improving sensitivity of liquid biopsy using 'loosely stacked' detection layers

By detecting DNA fragments in body fluids like urine, some types of cancer can already be traced in an early stage. But in order to capture them, detection sensitivity has to be improved.

Tumor suppressor gene represses 'jumping genes'

About half of all tumors have mutations of the gene p53, normally responsible for warding off cancer. Now, UT Southwestern scientists have discovered a new role for p53 in its fight against tumors: preventing retrotransposons, or "jumping genes," from hopping around the human genome.

Multimodal mapping of immune landscape in pancreatic cancer could guide personalized therapies

Pancreatic cancer has remained resistant to immunotherapies that are revolutionizing the treatment of many types of cancer.

Researchers create AI system that matches tumors to best drug combinations

Only 4 percent of all cancer therapeutic drugs under development earn final approval by the U.S. Food and Drug Administration (FDA).

Tumor DNA in spinal fluid can help track children with aggressive brain tumors

For many cancers, doctors are increasingly looking to the DNA that solid tumors shed into the blood stream to help with diagnosis and monitoring. But brain cancer has been a different story thanks to the natural blockade created by the blood-brain barrier.

Scientists develop a way to accurately detect and monitor common pediatric brain cancer

A team of scientists at Texas A&M University, Baylor College of Medicine and Texas Children's Hospital have developed a way to more accurately both detect and monitor a common type of pediatric brain cancer, setting the stage for giving clinicians a real-time view into how the cancer responds to treatment.

Scientists use gold nanorod scattering to identify changes in macrophages

Every biological system is naturally equipped with a defense mechanism to protect against abnormal changes caused by either local, environmental, or biochemical alteration. White blood cells play the role of such a 'soldier' in our immune response.
