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.

Mayo Clinic provides new strategy for designing better treatments for juvenile dermatomyositis

Mayo Clinic researchers, working with colleagues at the University of Minnesota and University of Pittsburgh, are the first to describe a new role for a specialized cell of the immune system in children suffering from a rare muscle-damaging disease known as juvenile dermatomyositis (JDM).

Those most at risk of Alzheimer's would allow loved ones enroll them in research

According to a new survey most people at high risk of Alzheimer's disease would be willing to have their loved ones enroll them in research studies when they could no longer give consent themselves.

Early diagnosis guarantees therapeutic success in breast cancer

Breast cancer is the most common tumour amongst the female population. In recent years its prevalence has increased considerably without the reasons thereof being very clear, although lifestyle changes such as first pregnancy taking place at a later age or the reduction in the period of breast-feeding may play an important role.

Breast magnetic resonance imaging helps doctors select best treatment for early breast cancers

Breast magnetic resonance imaging enhances patient selection for accelerated, partial breast irradiation by detecting previously unsuspected, microscopic lesions within the breast, according to a study presented October 17, 2005, at the American Society for Therapeutic Radiology and Oncology's 47th Annual Meeting in Denver.

Performing a sentinel node biopsy prior to mastectomy and reconstruction gives best results

Altering the standard step-by-step procedure that takes women facing a mastectomy from diagnosis to surgery to reconstruction can improve the process and help in determining if immediate reconstruction is the best course of action, according to new research from the University of North Carolina at Chapel Hill.

Frequency and cause of errors in cancer diagnosis

Procedures used to obtain and examine tissue for cancer diagnosis are prone to error that frequently results in harm, according to a new study published in the November 15, 2005 issue of CANCER, a peer-reviewed journal of the American Cancer Society.

Tonsils reveal information that helps understand lupus

By snipping out and analyzing tiny samples of patients' tonsils, scientists have identified a key cellular checkpoint that is somehow bypassed in lupus patients, where harmful immune cells that normally are squelched by the body are mistakenly granted access.

Minimally invasive needle breast biopsies and sentinel node biopsies should be performed more routinely than they currently are

Physicians should strive to replace traditional, invasive procedures for diagnosing breast cancer with proven, less-invasive diagnostic methods, according to an international panel of breast cancer experts convened at the Keck School of Medicine of the University of Southern California.

Cells inside the hair follicle are true multipotent stem cells

Using an animal model, a research team led by Yann Barrandon at the EPFL (Ecole Polytechnique Federale de Lausanne) and the CHUV (Lausanne University Hospital) has discovered that certain cells inside the hair follicle are true multipotent stem cells, capable of developing into the many different cell types needed for hair growth and follicle replacement.

Treatment of Nonalcoholic Fatty Liver Disease (NAFLD) in children

The Nonalcoholic Steatohepatitis (NASH) Clinical Research Network has launched its second clinical trial to study NASH, a liver disease that resembles alcoholic liver disease but occurs in patients who drink little or no alcohol. The first trial, launched in January of this year, focuses on adults, while the second trial studies the disease in children.

Digital mammography and breast cancer in older women

Digital mammography that uses computers to detect breast cancer found significantly (up to 28%) more cancers than screen film mammography in women 50 and younger, premenopausal and perimenopausal women, and women with dense breasts, according to results from one of the largest breast cancer screening studies ever performed.

Combining optical tomography with standard ultrasound imaging can help distinguish early-stage breast cancer

A new study shows that combining a technology called optical tomography with standard ultrasound imaging can help distinguish early-stage breast cancer from non-cancerous lesions--and potentially reduce the number of breast biopsies performed. The study appears in the October issue of the journal Radiology.

Computer-aided detection useful in detecting small tumors in young women

A computer-aided detection system not only helps radiologists detect more breast cancers, but also helps detect smaller tumors in younger women, a new study shows.

22 biomarkers that provide a more accurate screening for prostate

Researchers at the University of Michigan Comprehensive Cancer Center have identified a panel of 22 biomarkers that together provide a more accurate screening for prostate cancer than the current prostate specific antigen, or PSA, test.

Digital mammography detects more cancers than screen film mammography

A landmark breast cancer screening trial shows that digital mammography detected more cancers - up to 28 percent more - than screen film mammography in women 50 and younger, premenopausal and perimenopausal women, and women with dense breasts.

3D gradient-echo MRI examinations useful in detecting most lethal of all major cancers

The study included 57 patients who had clinical symptoms of pancreatic cancer. All had contrast enhanced 3D gradient-echo MRI examinations.

New way to assess risk of breast cancer recurrence

Currently, the best way to predict whether a breast cancer is likely to recur is to determine whether tumor cells have invaded the lymph nodes near the breast.

Toluidine blue dye reveals oral cancers

A team of Canadian scientists may have discovered a way to use a simple dye as a litmus test to identify abnormal areas of the mouth that may become cancers.

Scientists help narrow the search for BRCA1 carriers

Cancer Research UK scientists have identified a new test which may help narrow the search for breast cancer patients likely to carry the faulty BRCA1 gene.

Experimental immunusuppressant drug preserves transplanted kidneys

An international team of transplant physicians has shown that the investigational drug belatacept (LEA29Y) preserves transplanted kidney function as effectively as cyclosporine, the drug most commonly used to prevent the immune system from rejecting transplanted organs.
