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.

Telemedicine approach remains a viable alternative for lung cancer screening

A novel telemedicine lung cancer screening effort during the COVID-19 pandemic shows that virtual single-visit screenings are just as effective as single-visit screenings done in person at the hospital, according to a study presented at the American College of Surgeons Virtual Clinical Congress 2021.

Cell-free DNA can help detect measurable residual disease in children with medulloblastoma

Scientists at St. Jude Children's Research Hospital have shown that cell-free DNA from cerebrospinal fluid (CSF) can be used to detect measurable residual disease (MRD) in children treated for the brain tumor medulloblastoma.

High levels of cancer-fighting immune cells could indicate a better chance of survival

Cancerous tumors are made up of many more components than just malignant cells from the tissue of origin. Immune cells can be recruited to the tumor site and form what is known as the tumor microenvironment.

Study shows how tissue-derived T cells can damage other organs in stem cell transplant patients

More than 40,000 allogeneic hematopoietic stem cell transplants are carried out worldwide every year, mostly for patients suffering from leukemia or other diseases of the hematopoietic system.

Kidney transplant patients are more susceptible to harmless bacterium, finds study

It's a pervasive bacterium found in soil and water that rarely causes disease, but a new national review of nocardia infection in people who have had a kidney transplant shows that when it occurs it most commonly causes pneumonia and brain abscess, and reminds their physicians to stay on the lookout for it, investigators say

Israeli Pfizer COVID vaccine/myocarditis study, 136 cases out of 5 million

A new study, published in the New England Journal of Medicine, aimed to present clinical, epidemiological, and follow-up findings of myocarditis cases diagnosed in temporal proximity to COVID-19 vaccination and explore the possibility of a causal relationship between the two.

New technology shows great promise for early diagnosis of Alzheimer’s disease

A technology developed by scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) shows great promise for diagnosing Alzheimer's disease before symptoms arise, potentially changing the course of research and treatment for this condition, which affects millions of people worldwide and is estimated to be the sixth leading cause of death in the United States.

Acute myocarditis extremely rare after COVID mRNA vaccination in adults

Now, a new study published in the journal JAMA Internal Medicine evaluated the incidence of acute myocarditis and clinical outcomes among adults who received the mRNA vaccine in an integrated health care system in the United States.

Scientists find new possibilities for treatment of lung cancers in 'never smokers'

Despite smoking's well-known role in causing lung cancer, a significant number of patients who develop lung tumors have never smoked. While scientists are still working to understand what spurs cancer in so-called "never-smokers," a study led by scientists at Washington University School of Medicine in St. Louis demonstrates new possibilities for treating these baffling tumors.
