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.

MD Anderson, Transgenomic partner to evaluate use of ICE COLD-PCR

Transgenomic, Inc. today announced that it has begun a collaboration with The University of Texas MD Anderson Cancer Center to evaluate the use of the Company's very high sensitivity ICE COLD-PCR mutation detection technology in analysis of DNA isolated from circulating tumor cells (CTCs) in blood samples from patients with advanced cancer.

Panel of 10 serum protein biomarkers could help in lung cancer diagnosis

A panel of serum biomarkers could help predict the level of lung cancer risk in high-risk patients, offering doctors an option before proceeding with a biopsy. Research presented in the April 2012 issue of the International Association for the Study of Lung Cancer's (IASLC) Journal of Thoracic Oncology shows that a panel of 10 serum protein biomarkers could help in the lung cancer diagnosis.

New national effort to accelerate development of therapies for neurological diseases

The National Institute for Neurological Disorders and Stroke (NINDS) has selected Columbia University College of Physicians and Surgeons and Weill Cornell Medical College to participate in a new national effort to accelerate the development of therapies for people with neurological diseases.

Tumors can be more complex than imagined earlier: Study

Researchers speculate that cancers may be more complex that they knew. And that's why a single tissue sample taken from a single tumor may not be the best way to figure out a course of treatment they claim.

First ever analysis of genetic variation between different regions of same tumour

Taking a sample from just one part of a tumour may not give a full picture of its 'genetic landscape', according to a landmark study published in the New England Journal of Medicine.

Ultrasound-based TE more accurate in detecting hepatic fibrosis

Researchers from the Mayo Clinic confirm that ultrasound-based transient elastography (TE) provides excellent diagnostic accuracy for detecting cirrhosis due to recurrent infection with hepatitis C virus (HCV) infection following liver transplantation.

On-site pathology evaluations cut operating time, reduce costs of breast cancer care

Nearly one in three women who have breast cancer surgery will need to return to the operating room for additional surgery after the tumor is evaluated by a pathologist.

Study aims to develop noninvasive method to analyze interstitial cystitis

A pilot study led by University of Kentucky researchers shows that the gene expression analysis of urine sediment could provide a noninvasive way to analyze interstitial cystitis in some patients.

Women over 40 have better prognosis after mammography screening

Based on a study of nearly 2,000 breast cancer patients, researchers at the Swedish Cancer Institute in Seattle say that, in women between the ages of 40 and 49, breast cancers detected by mammography have a better prognosis. The study appears in the March issue of Radiology.

Targeting versican protein may help stop breast cancer metastasis

Oncologists have known that in order for cancer cells to spread, they must transform themselves so they can detach from a tumor and spread to a distant organ. Now, scientists at Weill Cornell Medical College have revealed critical steps in what happens next -- how these cells reverse the process, morphing back into classical cancer that can now grow into a new tumor.

OICR launches Phase III Active Surveillance Magnetic Resonance Imaging Study Trial

Dr. Nicole Onetto, Deputy Director and Chief Scientific Officer of the Ontario Institute for Cancer Research (OICR), today announced the launch of an innovative Phase III clinical trial that aims to determine whether multi-parametric magnetic resonance imaging (MRI) coupled with transrectal ultrasound (TRUS) guided biopsy (called fusion technology) can accurately identify men with prostate cancer who are at risk of developing aggressive disease.

Low choline intake increases risk of liver scarring in menopausal women with NAFLD

Menopausal women with non-alcoholic fatty liver disease (NAFLD) who don't consume enough of the essential nutrient choline appear to be at higher risk for liver scarring, according to research led by scientists at Johns Hopkins Children's Center.

Gen-Probe receives FDA approval for PROGENSA PCA3 assay

DiagnoCure, Inc., a Quebec life sciences company that develops and commercializes high‐value cancer diagnostic tests, announced today that the US Food and Drug Administration (FDA) has approved Gen-Probe's PROGENSA PCA3 (Prostate Cancer Antigen 3) assay, the first molecular test to help determine the need for repeat prostate biopsies in men who have had a previous negative biopsy.

Heart attack scars mended using stem cells

Researchers from United States have successfully healed the scars caused by a heart attack using stem cells gathered from the patient's own heart. The amount of scar tissue was halved in the small safety trial reported in the Lancet medical journal. The authors said there was also an “unprecedented” increase in new heart muscle.

Machine-learning methods show that patients with severe brain injury could communicate accurately

Only by employing complex machine-learning techniques to decipher repeated advanced brain scans were researchers at NewYork-Presbyterian/Weill Cornell able to provide evidence that a patient with a severe brain injury could, in her way, communicate accurately.

Link between coronary artery disease and prostate cancer

In a large analysis of men participating in a prostate drug trial, researchers at the Duke Cancer Institute found a significant correlation between coronary artery disease and prostate cancer, suggesting the two conditions may have shared causes.
