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.

Non-invasively measuring liver stiffness with transient elastography accurately identifies advanced liver disease without biopsy

Non-invasively measuring liver stiffness with transient elastography accurately diagnoses patients with late-stage liver disease, reports a new study in Clinical Gastroenterology and Hepatology, the official journal of the American Gastroenterological Association (AGA) Institute.

Endoscopic ultrasound 99.1 percent accurate in diagnosing pancreatic neoplasms

Researchers from St. Louis University School of Medicine in Missouri report that EUS and EUS-FNA is 99.1 percent accurate in diagnosing pancreatic neoplasms (abnormal growths or tumors) in patients who were referred for endoscopic ultrasound (EUS) because of CT and/or MRI reports of two common, though somewhat ambiguous findings - enlargement of head of pancreas (HOP) or dilation of the pancreatic duct (PD).

Sniffing out skin cancer by smell

According to researchers in the U.S. the smell skin gives off could indicate the presence of skin cancers. They say cancers such as basal cell carcinomas can be identified by the odour on the skin.

SpectraScience awarded U.S. patent for correcting image misalignment

SpectraScience, Inc. has announced that it has been awarded a patent for correcting image misalignment between at least two images in a sequence of images due at least in part to tissue sample movement. The patent, U.S. Patent No. 7,406,215, is titled "Methods and systems for correcting image misalignment."

Research team creates human ALS motor neurons

A team of researchers from the Harvard Stem Cell Institute (HSCI) and Columbia University, in a collaboration catalyzed by the Project A.L.S./Jenifer Estess Laboratory for Stem Cell Research, has demonstrated that pluripotent stem cells generated from a patient with ALS (amyotrophic lateral sclerosis) can be directed to differentiate into motor neurons - the very brain cells destroyed by ALS.

Researchers locate and image prostate cancer as it spreads to lymph nodes

Using an engineered common cold virus, UCLA researchers delivered a genetic payload to prostate cancer cells that allowed them, using Positron Emission Tomography (PET), to locate the diseased cells as they spread to the lymph nodes, the first place prostate cancer goes before invading other organs.

Circulating tumor cells can reveal genetic signature of dangerous lung cancers

Using a miniature laboratory-on-a-chip device, a team of investigators at the Massachusetts General Hospital, led by Daniel Haber, M.D., Ph.D., and Mehmet Toner, Ph.D., both members of the MIT-Harvard Center for Cancer Nanotechnology Excellence (CCNE), has developed a method that detects and analyzes the genetic signature of rare tumor cells in the bloodstream.

AMDL granted FDA clearance to market blood test for colorectal cancer

AMDL has announced that the US Food and Drug Administration (FDA) has issued a letter of substantial equivalence to an existing predicate device and granted clearance to market the AMDL-ELISA DR-70(R) (FDP) as a safe and effective blood test for monitoring patients who have been previously diagnosed with colorectal cancer (CRC).

Microchip-based device determines the genetic signature of lung tumors

Massachusetts General Hospital (MGH) investigators have shown that an MGH-developed, microchip-based device that detects and analyzes tumor cells in the bloodstream can be used to determine the genetic signature of lung tumors, allowing identification of those appropriate for targeted treatment and monitoring genetic changes that occur during therapy. A pilot study of the device called the CTC-chip will appear in the July 24 New England Journal of Medicine and is receiving early online release.
