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.
Breast ultrasound examination may eliminate need for biopsy in teens with breast lumps

Breast ultrasound examination may eliminate need for biopsy in teens with breast lumps

If a lump is found in the breast of an adolescent girl, she often will undergo an excisional biopsy. However, breast cancer is rare in adolescents, and the vast majority of teenage breast lumps turn out to be benign masses that are related to hormones and often go away over time. [More]

MRI technique may help detect cancerous cells

MRI technique may help detect cancerous cells

Imaging tests like mammograms or CT scans can detect tumors, but figuring out whether a growth is or isn't cancer usually requires a biopsy to study cells directly. Now results of a Johns Hopkins study suggest that MRI could one day make biopsies more effective or even replace them altogether by noninvasively detecting telltale sugar molecules shed by the outer membranes of cancerous cells.

GFT505 demonstrates dose-dependent efficacy on primary endpoint in phase 2 NASH trial

GFT505 demonstrates dose-dependent efficacy on primary endpoint in phase 2 NASH trial

GENFIT, today announces topline results of the phase 2 GOLDEN-505 trial in NASH. Due to the unexpected rate of resolution of NASH in patients randomized to placebo who had early NASH (NAS of 3, placebo response rate>57%), along with the high number of sites for a limited sample size, the study as initially designed did not enable the trial to meet directly the primary endpoint.

New imaging technique could give precise information about structures inside tissues, cells

New imaging technique could give precise information about structures inside tissues, cells

One infrared scan can give pathologists a window into the structures and molecules inside tissues and cells, enabling fast and broad diagnostic assessments, thanks to an imaging technique developed by University of Illinois researchers and clinical partners. [More]

Vitamin D3 and metformin show promising results in preventing colorectal cancer

Vitamin D3 and metformin show promising results in preventing colorectal cancer

The concept was simple: If two compounds each individually show promise in preventing colon cancer, surely it's worth trying the two together to see if even greater impact is possible. [More]

Scientists use optical radiation to treat cancer at the cellular level

Wanting to achieve early cancer detection, a group of scientists from the Center for Research in Optics (CIO) of Guadalajara, in Mexico, seeks to address the problem from the cell with optical radiation. [More]
Women diagnosed with DCIS or atypia should seek second opinions, says study

Women diagnosed with DCIS or atypia should seek second opinions, says study

While doctors almost always agree on a pathological diagnosis of invasive breast cancer, there is room for improvement when diagnosing atypia (or atypical ductal hyperplasia-ADH) and DCIS (ductal carcinoma in-situ), Anna Tosteson, ScD and Tracy Onega, PhD from Dartmouth-Hitchcock's Norris Cotton Cancer Center have found.

Promising new treatment for hereditary breast/ovarian cancer

European scientists recently discovered a novel therapy to treat a subgroup of patients with hereditary breast/ovarian cancer. Both the EU and the US have approved an accelerated procedure to market this promising new treatment with few side effects. [More]
MRI more accurate, safe and less painful than liver biopsy in measuring total body iron balance

MRI more accurate, safe and less painful than liver biopsy in measuring total body iron balance

Investigators at The Saban Research Institute of Children's Hospital Los Angeles have demonstrated that MR imaging of the liver is more accurate than liver biopsy in determining total body iron balance in patients with sickle cell disease and other disorders requiring blood transfusion therapy.

New diagnostic method replaces surgery for bowel tumor assessment

New diagnostic method replaces surgery for bowel tumor assessment

A new study at the MedUni Vienna's Comprehensive Cancer Center is assessing patients with metastasised bowel cancer to determine whether it is possible to characterise tumour and better control resistance mechanisms with a blood test. The aim of this is to spare patients the stress of having tissue removed via biopsies and to make the targeted use of therapy easier. [More]

Biomarker for compilation of Risk Score for non-alcoholic steatohepatitis

Biomarker for compilation of Risk Score for non-alcoholic steatohepatitis

40 percent of people in the EU suffer from non-alcoholic steatohepatitis (fatty liver disease), a disease which is becoming increasingly more frequent as a result of diabetes and excess weight in an affluent society. Currently, it is not possible to forecast the further course of the disease - right up to cirrhosis and cancer of the liver. Furthermore, an increased risk of heart attack and kidney damage exists. In future, this should become possible using a Risk Score with different biomarkers. [More]
