Alarming number of women undergo open surgery when minimally invasive biopsy has demonstrated equivalent accuracy, less cost and reduced risk of scarring A special report published in the October issue of the Journal of the American College of Surgeons indicates that an alarming 35% of initial diagnostic breast biopsies in the United States are still being done using unnecessary open surgical techniques. This in spite of the fact that it costs as much as three times more than the much less...

Researchers have developed a new breast biopsy technique that could lead to decreased procedure times and reduced patient discomfort and morbidity, according to a study performed at Roberts Research Institute, the University of Western Ontario and London Health Sciences Centre, London, ON, Canada. The new technique uses a mechanical arm to guide the needle for the biopsy and has a braking system to allow for accurate placement of the needle and to avoid needle motion.Breast biopsy procedures,...

After a review of 284 cases, specialists at the Brain Tumor Center at the University of Cincinnati (UC) Neuroscience Institute have concluded that performing a stereotactic needle biopsy in an area of the brain associated with language or other important functions carries no greater risk than a similar biopsy in a less critical area of the brain.The retrospective study, led by Christopher McPherson, MD, director of the division of surgical neuro-oncology at UC and a Mayfield Clinic...

Stereotactic vacuum-assisted breast needle biopsy, a common minimally invasive biopsy method used in the US, is more effective with an 11-gauge needle than the 14-gauge needle decreasing a physician's chances of false-negative diagnoses, according to a study performed at the Stanford University School of Medicine in Stanford, CA.The study included 1,280 breast lesions that were consecutively biopsied using a 14-gauge or 11-gauge vacuum needle. Results showed that cancer was missed in 3/68...

By Lachar, Whitney A Shahab, Imran; Saad, A Joe * Context.-Lymphomas have traditionally been diagnosed on excisional biopsies of lymph nodes in order to evaluate tissue architecture and cytomorphology. Recent lymphoma classification schemes emphasize immunophenotypic, genetic, and molecular aspects in addition to morphology as diagnostic features. Core needle biopsies are increasingly being used to obtain tissue for diagnosis in patients with lymphadenopathy and a clinical suspicion of...

LOS ANGELES, Oct. 6 - 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. In a consensus paper published in October's Journal of the American College of Surgeons (JACS), 23 leading surgeons, radiologists, pathologists and oncologists say minimally invasive...

Inserting biopsy needles through the skin appears to be a safe and reliable alternative to surgery for obtaining diagnostic samples of a suspected solid tumor in children, according to results of a study by investigators at St. Jude Children's Research Hospital. The technique, called percutaneous ("through the skin") core-needle biopsy, provides samples of tissue suitable for accurate initial diagnosis of a solid tumor, the researchers say. In addition, the findings contradict the belief of...
