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.

Insomnia linked to GERD in nonalcoholic fatty liver disease

Insomnia appears to be relatively common in patients with nonalcoholic fatty liver disease and may occur, at least in part, as a result of gastroesophageal reflux disease symptoms, report researchers.

Thyroid ultrasound imaging may identify patients with low risk of cancer, can help postpone biopsy

Thyroid ultrasound imaging could be used to identify patients who have a low risk of cancer for whom biopsy could be postponed, according to a study by Rebecca Smith-Bindman, M.D., of the University of California, San Francisco, and colleagues.

Noninvasive urine test can accurately monitor risk of kidney rejection

Levels of a protein in the urine of kidney transplant recipients can distinguish those at low risk of developing kidney injury from those at high risk, a study suggests. The results also suggest that low levels of this protein, called CXCL9, can rule out rejection as a cause of kidney injury.

New data analyzing technique via MR imaging identify tumors' response to anti-angiogenesis therapy

A new way of analyzing data acquired in MR imaging appears to be able to identify whether or not tumors are responding to anti-angiogenesis therapy, information that can help physicians determine the most appropriate treatments and discontinue ones that are ineffective.

DLBCLs resistant to chemotherapy can be reprogrammed to respond using azacitidine

A phase I clinical trial showed diffuse, large B-cell lymphomas (DLBCLs) resistant to chemotherapy can be reprogrammed to respond to treatment using the drug azacitidine, according to a study published in Cancer Discovery, a journal of the American Association for Cancer Research.

New treatment technique uses nanoparticles to attack cancer

Researchers at the University of Georgia are developing a new treatment technique that uses nanoparticles to reprogram immune cells so they are able to recognize and attack cancer. The findings were published recently in the early online edition of ACS Nano.

Researchers discover the origin of HPV-related tonsillar cancer

American and European research shows an alarming increase in the rate of tonsillar cancer related to the human papilloma virus (HPV), a sexually transmitted virus. Experts suggest a similar trend has emerged in Canada, but it had yet to be confirmed through scientific analysis.

New microfluidic chip can capture live CTCs from patient's blood

Tumor cells circulating within a patient's bloodstream can carry cancer from a primary tumor site to distant sites of the body, spreading the disease.

Standardizing care for penile cancer

Penile cancer is rare, with an average of 1,200 new cases per year in the United States, but it can be debilitating and lethal. Without evidenced-based treatment approaches, outcomes have varied widely. Philippe E. Spiess, M.D., an associate member in the Department of Genitourinary Oncology at Moffitt Cancer Center, presented new National Comprehensive Cancer Network Clinical Practice Guidelines in Oncology to standardize care for penile cancer in an article that appeared in the July issue of the Journal of the National Comprehensive Cancer Network.

Frozen sperm taken by biopsy from testicles may help couples conceive through IVF

Frozen sperm taken by biopsy from testicles in men with no sperm in their semen is as effective as fresh sperm taken by biopsy in helping couples conceive through in vitro fertilization (IVF), according to a study at Washington University School of Medicine in St. Louis.

Electronic communication unlikely to be widely adopted by physician practices

Patients like it and so do health organizations, but electronic communications in clinical care will likely not be widely adopted by primary care physicians unless patient workloads are reduced or they are paid for the time they spend phoning and emailing patients, both during and after office hours.
