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.

Prostate size growth not necessarily a predictor of development of cancer

New Mayo Clinic research studied the association between prostate-specific antigen (PSA) levels and prostate size and found that routine annual evaluation of prostate growth is not necessarily a predictor for the development of prostate cancer. However the study suggests that if a man's PSA level is rising quickly, a prostate biopsy is reasonable to determine if he has prostate cancer.

World's smallest gastrointestinal videoscope with four-way angulation and NBI

Olympus today introduced the world's smallest gastrointestinal videoscope to offer four-way angulation and Narrow Band Imaging™ (NBI) to detect upper gastrointestinal abnormalities. The super-slim scope is 5.5 mm in diameter at the distal end, as well as the insertion tube, and offers exceptional insertion capability to enhance patient comfort. The scope also features NBI, Olympus' proprietary imaging technology that filters white light to consist of specific wavelength bands enabling enhanced observation of microvessels and subtle changes on the mucosa.

Minimally invasive surgical techniques as effective as traditional open surgery in treating rectal cancers

Laparoscopic surgery has been used in the treatment of intestinal disorders for close to 20 years, but its benefits have only recently begun to be extended to people with rectal cancer. In a prospective study of 103 patients who underwent straightforward or "hand-assisted" laparoscopic surgery for rectal cancer, a team of colon and rectal surgeons at NewYork-Presbyterian Hospital/Weill Cornell Medical Center has shown that the minimally invasive approach can be as effective as traditional open surgery in treating rectal cancers.

NIDA supports new drug detection research

Every time a person snorts cocaine, it doesn't just go to his or her head: It also provokes a response in the immune system, creating special biomolecules that may serve as a permanent record of each exposure.

Study: Patients with difficult to treat hepatitis C are half as likely to initiate treatment

A new study by Mount Sinai researchers has for the first time found that patients with more difficult to treat forms of hepatitis C are half as likely to initiate treatment for the disease, when compared to patients with hepatitis C that is easier to treat. Marital status also affected whether patients chose treatment, as did whether or not they had other diseases.

Prepubertal boys with cancer can bank on their testicular tissue for preserving fertility

For parents of children with cancer, the hopeful news is that pediatric survival rates have steadily improved for decades. Among the bad news-treatments that enable survival often cause infertility.

New technique to identify patients more likely to survive advanced melanoma

Although the chances of surviving advanced melanoma aren't very good with current therapies, some patients can live for years with cancer that has spread beyond the skin to other organs. Now it may be possible to identify which patients are more likely to survive by analyzing the activity of hundreds of genes involved in the immune response and gene proliferation, according to researchers at NYU Langone Medical Center.

Elevated PSA levels in men are not necessarily a predictor of the need for a prostate biopsy: Study

Researchers at Wake Forest University School of Medicine and the University of Wisconsin-Madison have discovered that some elevated prostate-specific antigen (PSA) levels in men may be caused by a hormone normally occurring in the body, and are not necessarily a predictor of the need for a prostate biopsy.

Results of LightTouch Non-invasive Cervical Cancer Detection Device trial presented

Results of the FDA pivotal clinical trial for the LightTouch™ Non-invasive Cervical Cancer Detection Device conducted by Guided Therapeutics, Inc.

Boosting NAD+ after spinal cord injury may prevent permanent nerve death

Substances naturally produced by the human body may one day help prevent paralysis following a spinal cord injury, according to researchers at Weill Cornell Medical College. A recent $2.5 million grant from the New York State Spinal Cord Injury Research Board will fund their research investigating this possibility.
