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.

African American men with prostate cancer have significantly lower PSA density than Caucasian men

A new study published in The Journal of Urology revealed that African American men with Gleason score 3+3=6 prostate cancer (PCa) produce less prostate specific antigen (PSA) and have significantly lower PSA density (PSAD) than Caucasian men. These findings could have important implications when selecting patients for inclusion in active PCa surveillance programs.

High diversity among circulating tumor cells predicts survival, treatment resistance in prostate cancer patients

Research teams at Memorial Sloan Kettering Cancer Center and Epic Sciences have found that greater diversity among circulating tumor cells (CTCs) in the blood of advanced prostate cancer patients predicts not only shorter overall survival, but also the development of resistance to key anti-androgen therapies.

Study identifies several risk factors linked to low patient-accrual rates in cancer clinical trials

A new study by researchers at the Hutchinson Institute for Cancer Outcomes Research at Fred Hutchinson Cancer Research Center and the University of Washington has found that 20 percent of cancer clinical trials fail to draw enough participants to render verdicts on experimental therapies.

Enteric nerves of irritable bowel syndrome patients respond poorly to inflammatory substances

For the first time, biopsies of patients with irritable bowel syndrome have shown that the nerves in their gut wall respond poorly to a cocktail of inflammatory substances. This refutes the previous theory that patients with irritable bowel syndrome have an overly sensitive gut.

Research opens door to validation studies in multiple tumor types of liquid biopsy

Pancreatic cancer tumors spill their molecular secrets into the blood stream, shedding their complete DNA and RNA wrapped inside protective lipid particles that make them ripe for analysis with a liquid biopsy, researchers at The University of Texas MD Anderson Cancer Center report online at the Annals of Oncology.

Repeating abnormal PSA tests can reduce unnecessary biopsies

For more than 20 years, the prostate-specific antigen (PSA) test has been used to help screen for prostate cancer, but in recent years, some task forces have called for this blood test to be abandoned because it leads to many unnecessary biopsies.
