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.

Long-term use of mechanical ventilation contributes to the deterioration of human diaphragm muscle

A new study by University of Pennsylvania School of Medicine shows, for the first time in humans, that ventilators combined with diaphragm disuse contributes to muscle atrophy in the diaphragm in as little as eighteen hours.

Uneven use of less-invasive breast cancer staging test reported

The use of sentinel lymph node biopsy (SLNB) during breast cancer surgery increased substantially from 1998 through 2005, according to an article published online March 25 in the Journal of the National Cancer Institute.

Nonalcoholic fatty liver disease related to cardiovascular fitness

Patients with nonalcoholic fatty liver disease (NAFLD) have suboptimal levels of cardiovascular fitness, muscle strength, body composition and physical fitness, according to a new study.

MRI opens up promising new avenues for non-invasive diagnoses and classification of cancer

Doctors diagnose and prescribe treatment for brain tumors by studying, under a microscope, tumor tissue and cell samples obtained through invasive biopsy or surgery.

New study confirms that PROGENSA PCA3 can improve accuracy of prostate cancer diagnosis

New clinical data from a study of 570 men published in the peer-reviewed Journal of Urology support the use of PROGENSA PCA3 as a tool for diagnosing prostate cancer. The study confirms that PROGENSA PCA3, the world's first gene-based urine test to help detect prostate cancer, can provide clinicians with valuable information that helps guide diagnosis.

Family communication impacts attitude about genetic counseling/testing for breast cancer

Whether or not relatives talk about the family's history of cancer significantly impacts attitudes and knowledge about genetic counseling and testing for those at moderate risk of developing breast cancer, according to a new preliminary study presented today at the American Society for Preventive Oncology meeting in Bethesda, Md.

New technique detects early stages of colon cancer without a biopsy

Doctors may one day be able to detect early stages of colon cancer without a biopsy, using a new technique developed by researchers at the Stanford University School of Medicine.

Routinely used diagnostic approaches: only limited diagnostic sensitivity for bile duct cancer?

Surgery is the only curative treatment in patients with bile duct cancer.

A long-term survival offered by resection of solid-pseudopapillary tumor of the pancreas?

The article published in volume 14 issue 6 of World Journal of Gastroenterology reports on one patient who presented to Dr Cosimo Sperti of University of Padua, Padova, Italy, in 2001 after an exploratory laparotomy performed in another hospital for an unresectable pancreatic cystic mass that had infiltrated the portal vein.

Discovery could lead to much-needed kidney failure treatment

The unwanted activation of an important cell-signaling pathway may play a role in two kidney problems that are major causes of end-stage renal disease, scientists at the Albert Einstein College of Medicine of Yeshiva University have found.

COX-2 expression is marker for cancer development in some benign breast biopsies

It's a good news, bad news situation. Some women who have a breast biopsy are told that while they don't have cancer, they do have atypical hyperplasia -- cells that aren't quite normal and might become cancerous someday.

Biopsy techniques have made PSA test less predictive

Prostate specific antigen (PSA) levels typically have correlated with prostate biopsy results in the detection of prostate cancer, but that correlation no longer exists for men with a normal prostate exam, according to a new study published in the April 15, 2008 issue of CANCER, a peer-reviewed journal of the American Cancer Society.

New way to assess a woman's risk for invasive breast cancer

Researchers at the University of California, San Francisco have developed a way to quickly estimate a woman's risk for invasive breast cancer.

Research in diabetes surgery suggests origins of disease

Growing evidence shows that surgery may effectively cure Type 2 diabetes -- an approach that not only may change the way the disease is treated, but that introduces a new way of thinking about diabetes.

Serum fibrosis markers correlate with liver fibrosis stage in patients with advanced chronic hep C

A prospective study of patients with advanced chronic hepatitis C (CHC) revealed that a 3-variable model of serum fibrosis markers, including serum HA, TIMP-1 and platelet count, could identify cirrhosis with better accuracy than other published models.

Gold nanoparticle-based colorimetric assay for the direct detection of cancerous cells

Early detection of tumors is one of the Holy Grails of cancer research, an achievement that would greatly improve cancer therapy and prognosis. Two new reports describe different but promising approaches to solving this problem.

Real-time imaging device may improve surgery for congenital colon disease

Researchers at Cedars-Sinai Medical Center are developing a spectral imaging system that could result in shorter operating times for infants undergoing surgery for Hirschsprung's disease, according to a mouse study reported in the Journal of Biophotonics.
