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.

Causes of hepatitis and potential therapies that may improve care presented in study

Hepatitis, a potentially serious disease caused by a virus that attacks the liver, is a major problem worldwide. Hepatitis A is generally food-borne, while hepatitis B and C spread primarily through parenteral or sexual routes. Hepatitis B and C can be life-long, potentially deadly chronic infections.

Inexpensive, simple urine test that could identify impending kidney failure

Johns Hopkins researchers have developed the basis of an inexpensive, simple urine test that identifies impending kidney failure or rejection following transplant surgery. Their work, presented this week in a special invited lecture to the American Transplant Congress in Boston, Mass., is based on proteins found in urine, and could lead to a urine test kit that may allow many patients to skip painful biopsies.

Fatty liver disease (NAFLD) in obese children has distinct characteristics different from those found in adults

Potentially life-threatening non-alcoholic fatty liver disease (NAFLD) in obese children has distinct characteristics, often different from those found in adults, according to a University of California, San Diego (UCSD) School of Medicine study led by Jeffrey Schwimmer, M.D., assistant professor of pediatrics.

Obesity epidemic and its impact on prostate cancer

Recent federal reports have identified obesity as epidemic in the United States, and that that greater body mass index can be associated with a number of debilitating health conditions, such as heart disease and diabetes.

Relationship between PSA score and prostate cancer has steadily declined

Results of a new study indicate that the relationship between PSA score and prostate cancer has steadily declined during the last 20 years, an important finding given that PSA score is often used to determine whether biopsy for prostate cancer testing is necessary.

No evidence of CJD associated with the Garden State Racetrack

The Department of Health and Senior Services released a report today on an investigation of a suspected cluster of Creutzfeldt-Jakob Disease (CJD) associated with the Garden State Racetrack.

Cervical Dysplasia treatment linked to water breaking too early

Two treatments for removing precancerous tissue from the cervix are associated with an increased risk of preterm delivery (delivery before 37 weeks gestation) caused by the pregnancy complication known as preterm premature rupture of membranes (PPROM).

Chemical thumbprint can help determine if tumor is returning or dying

Brain tumor survivors live with the constant worry that their cancer might come back. And even if they have a brain scan every few months to check, doctors often can't tell the difference between new cancer growth and tissue changes related to their treatment with radiation or chemotherapy.

Researchers profile over 6000 genes in the two primary types of normal breast cells

For several years, scientists have attempted to identify gene expression changes, using microarrays or ‘DNA chips’, in order to understand and predict breast cancer onset, progression, and clinical outcome.

Pediatric thyroid cancer is most common amongs teenage girls

Thyroid carcinoma is the third most common tumor malignancy in children. This pediatric cancer shares several characteristics with adult thyroid cancer patients including common cellular subtypes that are papillary, follicular and medullary; a female to male ratio is approximately 6:1; and a cervical nodal disease that can be observed at the time of presentation in 30-60 percent in both papillary and follicular malignancies.

Certain cells from a mother can cause immunity illness in children

Certain cells from a mother persist in their children’s bodies and can provoke an immune response in which the child’s body attacks itself, according to Mayo Clinic research published in the current issue of the Journal of Immunology (http://www.jimmunol.org).

Extraction of RNA from Archived Formalin-Fixed, Paraffin-Embedded Tissue

For the first time, Fox Chase Cancer Center researchers have demonstrated the ability to extract RNA from formalin-fixed, paraffin-embedded tissue samples archived for up to five years. What's more, the technology used retrieves high-quality samples, allowing researchers to identify cancer-related genetic changes. Accepted as a "late-breaking" abstract, the research was presented today at the 95th Annual Meeting of the American Association for Cancer Research by Renata Coudry, M.D., a research pathologist at Fox Chase Cancer Center.
