Biopsy News and Research RSS Feed - Biopsy News and Research

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.
Neurosurgeon performs first endoscopic removal of spinal tumor at Rhode Island Hospital

Neurosurgeon performs first endoscopic removal of spinal tumor at Rhode Island Hospital

The spinal tumor grew back. Even though the 16-year old patient endured surgery a year earlier to remove and diagnose the lesion, it was back and its cause unknown. Determined to identify the tumor tissue and set the patient on an appropriate treatment regimen, Albert Telfeian, M.D., a neurosurgeon at Rhode Island Hospital and Hasbro Children's Hospital, performed the first reported case of extracting the tumor endoscopically while the patient was awake and under a local anesthetic.

Researchers identify chemical pathway associated with seizures, shorter survival in patients with malignant glioma

Researchers identify chemical pathway associated with seizures, shorter survival in patients with malignant glioma

Researchers at the University of Alabama at Birmingham have identified a chemical pathway that may be associated with seizures and shorter patient survival in some patients with malignant glioma, the most common and deadly form of brain tumor. In findings published May 27 in Science Translational Medicine, the researchers suggest that a transporter known as SXC is responsible for boosting levels of glutamate in the brains of some glioma patients.

Researchers call for improving screening accuracy to reduce false-positive mammograms

Researchers call for improving screening accuracy to reduce false-positive mammograms

The psychological strain of being told that you may have breast cancer may be severe, even if it turns out later to be a false alarm. This is the finding of new research from the University of Copenhagen, which has just been published in the scientific journal Annals of Family Medicine. [More]
Six research teams awarded grant to accelerate discovery of new drugs for brain, nervous system disorders

Researchers reveal molecular steps that allow pancreatic cancer to spread to the liver

Researchers reveal molecular steps that allow pancreatic cancer to spread to the liver

An international team led by Weill Cornell Medical College investigators has illuminated the precise molecular steps that enable pancreatic cancer to spread to the liver -- the event that makes the most common form of the disease lethal. By understanding this process, investigators say their discovery can lead to targeted treatments that delay metastasis, and could offer clinicians a new biomarker to test for the earliest signs of pancreatic cancer.

Researchers report new label-free chemical imaging that provides similar information as molecular stains

Researchers report new label-free chemical imaging that provides similar information as molecular stains

Histopathology is a cornerstone of modern biomedical research. Yet, the practice of histopathology has evolved just a few times -- non-specific stains in the late 19th century, immunohistochemical staining in the mid-to-late 20th century and digital imaging/computerized analysis at the turn of the 20th century. In all cases, prepared biopsy samples are stained and examined under a light microscope. [More]
