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.

Aspirin lowers PSA levels

The use of aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs) is significantly associated with lower PSA levels, especially among men with prostate cancer, say researchers at Vanderbilt University.

Gail model no better than coin flip in predicting risk of breast cancer

A statistical model commonly used to predict the risk of breast cancer in women was not accurate when used to evaluate women with atypical hyperplasia, according to a new Mayo Clinic study published in the Oct. 14, 2008, issue of the Journal of Clinical Oncology.

New model helps estimate radiation skin doses during CT-guided interventional procedures

A new model that would allow interventional radiologists (radiologists who specialize in fine needle aspiration, fine needle biopsy and radiofrequency ablation) to better estimate patient radiation skin doses during CT guided interventional procedures has been developed according to a study performed at the Agios Savvas and Konstantopoulio Hospitals in Athens, Greece.

YM Biosciences reports on early trials of nimotuzumab in brain metastases and high-grade glioma

YM BioSciences Inc. has announced data from two clinical trials of nimotuzumab, its humanized monoclonal antibody that targets the epidermal growth factor receptor (EGFR). Preliminary results from the two trials which are evaluating nimotuzumab in combination with radiation therapy for the treatment of brain metastases and high-grade gliomas, conducted by YM's licensor, were presented at the 2008 EORTC-NCI-AACR annual meeting recently held in Geneva, Switzerland.

Sensitive ultrasound to spot early-stage cancer

European researchers have developed highly sensitive ultrasound equipment that can detect tiny quantities of reflective microbubbles engineered to stick to specific tumour cells. The technique should pick up tumours early and improve patients' chances of survival.

NIH tackles urologic chronic pelvic pain disorders

The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), part of the National Institutes of Health (NIH), announces awards to eight academic research centers to conduct collaborative studies of urologic chronic pelvic pain disorders by looking for clues outside the bladder and prostate. The total research investment for the five-year project is estimated to be up to $37.5 million.

CDC MMR/autism study - wrong questions asked, wrong children studied, wrong conclusions NAA says

A Centers for Disease Control and Prevention (CDC) study released today claims there is no link between the MMR vaccine and autism. The National Autism Association (NAA) says this study does nothing to dispel the growing public concern over a vaccine-autism connection and raises several questions concerning design and methodology.

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.
