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.

Q. What turns an obese person into a person with diabetes? - A. Leptin

Twin epidemics of obesity and type 2 diabetes are bearing down on the world's population, threatening the lives of hundreds of millions of people. But scientists are still trying to determine how the two conditions are linked, and what it takes to turn an obese person into a person with diabetes.

Patients can now swallow pill-sized, disposable cameras to help diagnose diseases of the esophagus

Patients can now swallow pill-sized, disposable cameras to help gastroenterologists diagnose and evaluate diseases of the esophagus, or swallowing tube. This new diagnostic tool is a further modification of capsule endoscopy, which has been used clinically since late 2001 to examine the small intestines.

Confocal imaging promises early detection of skin cancer

Detecting skin cancer early saves lives, but is a job for specialists. A new European system based on confocal imaging promises to improve detection and diagnosis rates by 20 per cent and to speed up the whole process considerably.

MRI useful in assessment of suspected breast cancer patients

If a mammogram or sonogram suggests that a woman has breast cancer, an MRI should be done to help determine whether there actually is a cancer and if so, what are the woman’s best treatment options, a new study shows.

Way to detect early signs of testicular cancer

Danish researchers have discovered a way to detect early signs of testicular cancer before it has started to spread. Their findings are the first step towards developing a simple screening test for men at risk of the disease.

People with osteoporosis should be screened for celiac disease

Results of a new study suggest that the higher prevalence of celiac disease in individuals with osteoporosis than in the general population may justify screening of patients with osteoporosis for celiac disease, according to an article in the February 28 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

Diagnosis of prions in patients should utilize novel strategy, conformation-dependent immunoassay

A technique for detecting prions in tissue, developed in recent years by UCSF scientists, is significantly more sensitive than the diagnostic procedures currently used to detect the lethal particles in samples of brain tissue from patients, according to a study performed by a UCSF team.

Why some lung cancers stop responding to the drugs erlotinib (Tarceva) and gefitinib (Iressa)

Researchers at Memorial Sloan-Kettering Cancer Center (MSKCC) have found an explanation for why some lung cancers stop responding to the drugs erlotinib (Tarceva) and gefitinib (Iressa).

"Frank Must Die" boy to undergo revolutionary surgery

A 9-year-old boy with brain cancer, who gained international attention when his mother launched an online auction to pay for his biopsy, will undergo the surgery at no cost thanks to internationally renowned surgeon Hrayr Shahinian, M.D. of the Skull Base Institute.

Role of ethnicity in nonalcoholic fatty liver disease

The first study to examine nonalcoholic fatty liver disease (NAFLD) among different ethnic and racial groups in the United States finds that Hispanics may be at a higher risk of developing the condition. The study is published in Hepatology, the official journal of the American Association for the Study of Liver Diseases (AASLD). Published by John Wiley & Sons, Inc., Hepatology is available online via Wiley InterScience.

Researchers attack cervical cancer

As more and more promising results of clinical trials on vaccination against human papillomaviruses are published, the more likely it becomes that an HPV vaccine will be the first licensed immunization against a sexually transmitted disease.

Many women at high risk for breast cancer are foregoing tamoxifen

Many women at high risk for breast cancer are foregoing tamoxifen, the first FDA-approved drug for prevention of breast cancer, due to concerns about side effects, increased risk of other cancers, and lack of information, a new study by researchers in Boston shows. The study was published in the December 14 in the Journal of Clinical Oncology.

Breast MRI moderately useful for detecting breast cancer

In women with breast lesions that are suspicious for cancer, based on clinical examination or mammography, performing a breast MRI has high sensitivity but only moderate specificity for detecting breast cancer, but does not necessarily eliminate the need for tissue sampling, according to a study in the December 8 issue of JAMA.

Heart Hospital begins experimental cell therapy

Physicians at the Heart Hospital became the first team in the UK to treat a patient with an experimental new therapy designed to repair damage to cardiac muscle resulting from a heart attack. If successful, this treatment would give doctors the ability to improve the hearts of people with heart failure, rather than just treating the symptoms.

New non-surgical technique that can help doctors determine when breast cancer has invaded the lymph nodes

A key question after a cancer diagnosis is whether the cancer has spread to nearby lymph nodes. Researchers at the University of Michigan Comprehensive Cancer Center have found a new non-surgical technique that can help doctors determine when breast cancer has invaded the lymph nodes, sparing some women an extra trip to the operating room.

Virtual colonoscopy raises issues for further study

The American Society for Gastrointestinal Endoscopy (ASGE) has reacted with caution to claims of the benefits of computed tomography (CT) colonography, also referred to as virtual colonoscopy, compared to standard colonoscopy.

New computer-aided diagnosis (CAD) methods for cancer

Not all masses are cancer. When a person undergoes a scan to identify a lump or nodule, the radiologist looks at the texture, the borders and the shape to determine if it is malignant or just a benign growth.
