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.

Combined DNA and protein 'liquid biopsy' more accurate in identifying early-stage pancreatic cancer

Johns Hopkins scientists say they have developed a blood test that spots tumor-specific DNA and protein biomarkers for early-stage pancreatic cancer.

Liquid biopsies show potential use for cancer screening

A new study has shown the potential of analyzing cell-free DNA (cfDNA) present in patients’ blood for cancer markers in early cancer detection. This technique was used in some instances for patients who already were diagnosed with a cancer as reported by some studies.

Blood biopsy helps identify targetable genetic alterations in patients with cancer of unknown primary

Using fragments of circulating tumor DNA in blood, University of California San Diego School of Medicine researchers were able to identify theoretically targetable genetic alterations in 66 percent of patients with cancer of unknown primary (CUP), a rare disease with seven to 12 cases per 100,000 people each year.

Researchers develop and validate new assay that detects gene fusions in solid tumors

An assay that identifies a peculiar but important abnormality in cancer cells has been developed and validated by researchers at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute.

Study shows how breast cancer cells spread late in disease development

Breast cancer cells that spread to other parts of the body break off and leave the primary tumor at late stages of disease development, scientists from the Wellcome Trust Sanger Institute and their collaborators have found.

New LF-OCT technology enables more accurate imaging of cellular processes in the eye

Optical Coherence Tomography (OCT) is a high-resolution live imaging technique that can be used for early detection of retinal diseases, such as age-related macular degeneration, diabetes-related conditions, glaucoma or vascular occlusions, for example.

Studies show how endoscopic procedures can improve outcomes and care

Gastrointestinal Endoscopy, the monthly peer-reviewed scientific journal of the American Society for Gastrointestinal Endoscopy, features a study reporting that a simpler procedure for collecting biopsy specimens during various procedures can improve patient care, and a study showing how a relatively new procedure, POEM, has been adapted to help an additional set of patients with gastroparesis, a troubling stomach problem.

Researchers develop potential stem cell treatment for several lung conditions

A team of scientists from the UNC School of Medicine and North Carolina State University has developed promising research towards a possible stem cell treatment for several lung conditions, such as idiopathic pulmonary fibrosis (IPF), chronic obstructive pulmonary disease (COPD), and cystic fibrosis -- often-fatal conditions that affect tens of millions of Americans.

FDA gives its nod to new drug Imbruvica (Ibrutinib) for chronic Graft versus Host Disease

The U.S. Food and Drug Administration (FDA) yesterday in a press release informed about the approval of Imbruvica (ibrutinib) for the treatment of adult patients with chronic graft versus host disease (cGVHD) who have previously failed with one or more treatment. This is the first drug that the FDA has given its approval to in this disease condition.
