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.

Triple drug combination keeps people with metastatic colon cancer disease free for longer time

Researchers from SWOG Cancer Research Network, a cancer clinical trials group funded by the National Cancer Institute (NCI), part of the National Institutes of Health, have shown that a triple drug combination - of irinotecan, cetuximab, and vemurafenib - is a more powerful tumor fighter and keeps people with metastatic colon cancer disease free for a significantly longer period of time compared with patients treated with irinotecan and cetuximab.

Researchers identify a driver of drug resistance in some cancers

Patients with BRCA1/2 mutations are at higher risk for breast, ovarian and prostate cancers that can be aggressive when they develop - and, in many cases, resistant to lifesaving drugs.

Detection of cancer using different kind of liquid biopsy

Because cancer is easier to successfully treat when it's caught early, a major goal in cancer research is to develop new ways to find tumors at early stages, before they start to spread. One approach that's being studied are liquid biopsies.

Researchers develop new method to diagnose brain tumor without incisions

Brain tumors are typically diagnosed using MRI imaging, as taking a sample for a tissue biopsy is risky and may not be possible due to tumor location or a patient's poor health conditions.

Deep learning algorithm can infer molecular alterations in cancer from histology images

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.

Gene biomarker can distinguish between atopic dermatitis and psoriasis with 100% 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.
