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.

Brazilian researchers identify new species of parasite in fatal case of visceral leishmaniasis

Brazilian researchers believe they have identified in patients treated at the University Hospital (HU) in Aracaju, state of Sergipe, a new species of parasite that can cause a disease similar to visceral leishmaniasis but is resistant to the treatments currently available.

Higher levels of genetic mutations linked to improved outcomes in lung cancer patients

According to new findings by Yale Cancer Center scientists, higher levels of genetic mutations in a tumor biopsy are linked to improved clinical outcomes in patients using pembrolizumab (Keytruda) to treat non-small cell lung cancer (NSCLC).

Pioneering melanoma test to be made available within two years

Scientists have developed a pioneering new test that can more accurately predict whether melanoma, a type of skin cancer, is likely to return.

Clinical trial to evaluate efficacy and safety of new treatment for giant cell arteritis

An international, multicenter phase II clinical trial is evaluating the efficacy and safety of mavrilimumab co-administered with a 26-week corticosteroid taper in patients with giant cell arteritis.

High-dose radiation effective for men whose prostate cancer has spread, trial shows

A randomized clinical trial of targeted, high-dose radiation for men with oligometastatic prostate cancer has shown the treatment to be an effective and safe option for patients who wish to delay hormone-suppression therapy.

Study shows miRNAs in semen as non-invasive biomarkers for prostate cancer

Researchers of the Human Molecular Genetics group at the Bellvitge Biomedical Research Institute, led by Dr. Sara Larriba, in collaboration with Dr. Francesc Vigués and Dr. Manel Castells of the Urology Service of Bellvitge University Hospital, show the usefulness of certain molecules, the miRNAs in semen, as non-invasive biomarkers for prostate cancer.

New genetic test could help avoid unnecessary prostate cancer surgery

Men who develop prostate cancer could avoid having unnecessary surgery or radiotherapy thanks to a new, more precise genetic test which is being trialed in Leeds.

UAB researchers find key role for IgG autoantibodies in IgA nephropathy

The most common form of the kidney disease called glomerulonephritis is IgA nephropathy.

Transperineal prostate biopsy minimizes risk of infection, may increase detection rate

Loyola Medicine is among the first centers to offer a new minimally invasive prostate biopsy that minimizes the risk of infection and may increase the cancer detection rate.

Men at high risk of breast cancer may benefit from screening, study shows

Men at high risk of developing breast cancer may benefit from mammography, or breast X-ray, screening for the disease, a new study shows.

PSA testing can help detect prostate cancer in men with BRCA2 gene fault

Men with the BRCA2 gene fault have an increased risk of prostate cancer and could benefit from PSA (prostate specific antigen) testing to help detect the disease earlier, according to researchers funded by Cancer Research UK.

New liquid biopsy test may be more predictive of patient's immunotherapy response

A new liquid biopsy test could detect microsatellite instability (MSI) and tumor mutational burden (TMB), indicating that it could help determine which patients are likely to respond to immune checkpoint inhibitors.

Non-invasive accurate blood test for prostate cancer

For men, one of the most dreaded moments could be hearing, “We’re not yet sure, but your PSA is high; you’ll have to come for further tests.” This could start a chain of events which ends in the diagnosis of prostate cancer - including a prostate biopsy, and ending in a major surgery for prostate removal.

Novel technology makes biopsies less invasive and more informative

A team of researchers from the National University of Singapore has developed a novel technology that could sensitively and accurately detect and classify cancer cells, as well as determine the disease aggressiveness from the least invasive biopsies.

Simple blood test found to efficiently, accurately detect aggressive prostate cancer

A new and simple blood test has been found to efficiently and accurately detect the presence of aggressive prostate cancer, according to research by Queen Mary University of London.

Liquid biopsies provide complete picture of genetic alterations linked to cancer drug resistance

Many patients see their tumors shrink in response to a drug, only to have them come back with a vengeance as they evolve to fend off the treatment. Oncologists want to be able to quickly detect cancer drug resistance as it emerges in their patients and identify another drug the tumors will still respond to.
