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.

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.

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.

Quest Diagnostics Health Trends study: HPV screening less likely to detect cervical cancer than cotesting

A Health Trends study from researchers at Quest Diagnostics and the University of Pittsburgh Medical Center provides new evidence that the HPV screening test is significantly less likely to detect cervical cancer and precancer than cotesting, a method which combines HPV and Pap testing using the same specimen.

No-biopsy diagnosis for adults with suspected celiac disease could cut long NHS waiting lists

The British Society of Gastroenterology has issued interim guidance, pending the publication of its new Coeliac Guidelines in 2021, so that some adults with suspected coeliac disease can now be diagnosed based on blood test results alone, cutting out the long wait for an endoscopy with biopsy.
