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.

Spinal muscular atrophy may lead to cardiac dysfunction: Study

Along with skeletal muscles, it may be important to monitor heart function in patients with spinal muscular atrophy (SMA). These are the findings from a study conducted by Nationwide Children's Hospital and published online ahead of print in Human Molecular Genetics. This is the first study to report cardiac dysfunction in mouse models of SMA.

Researchers recommends robotic prostatectomy over traditional open surgery method

While sharp debate continues among medical professionals as to whether a radical prostatectomy performed with the assistance of a robotic device is more beneficial than the traditional open surgery method, research just published by investigators at The Cancer Institute of New Jersey (CINJ) shows new evidence supporting the safety of the robotic procedure - including what is believed to be one of the lowest complication rates to date. CINJ is a Center of Excellence of UMDNJ-Robert Wood Johnson Medical School.

Scientists develop laser probe for early detection of oral cancer

UC Davis researchers have developed a laser probe for the early detection of oral cancer. A trial with human subjects shows that the device could also be used during surgery to locate the edges of a tumor.

New MIC platform measures cell-signaling pathways in brain tumor samples at single-cell level

New technologies for the diagnosis of cancer are rapidly changing the clinical practice of oncology. As scientists learn more about the molecular basis of cancer, the development of new tools capable of multiple, inexpensive biomarker measurements on small samples of clinical tissue will become essential to the success of genetically informed and personalized cancer therapies.

New trend in management of post-liver transplantation biliary strictures

Endoscopic intervention has emerged to become the first line treatment for benign biliary strictures following liver transplantation. The current endoscopic approach involves repetitive dilatation of the stricture and placement of multiple large-diameter parallel plastic stents with frequent stent exchange to prevent biliary infection.

VBDS secondary to nevirapine use in HIV-positive, pregnant female: Report

Vanishing bile duct syndrome refers to a group of disorders characterized by destruction and disappearance of intrahepatic (inside the liver) bile ducts. Multiple causes have been identified including infections, malignancies, autoimmune conditions and adverse effects of medications. The usual course of this condition is variable and many patients with VBDS respond to treatment of the underlying condition and/ or removal of the offending agent. However, others progress to cirrhosis and end stage liver disease requiring liver transplantation.

Functional MRI can be used to assess tumor viability

Pancreatic ductal adenocarcinoma (the disease commonly referred to as pancreatic cancer) carries the worst prognosis of any cancer. As current treatments offer minimal benefit, entirely new approaches are needed. Given the success of local therapies, as opposed to intravenous systemic therapies, for liver diseases (such as hepatocellular carcinoma), it is thought that similar local therapies may benefit patients with pancreatic cancer. To develop such therapies, it would be useful to devise targets that are easy to obtain and can indicate the efficacy of these new therapies in models of pancreatic cancer.

Despite all advancements in melanoma diagnosis, rapid treatment remains critical: Report

Twenty-five years after publishing the mnemonic "ABCD" to facilitate the early diagnosis of melanoma, the group who came up with that moniker says early detection remains a key factor in lowering mortality from malignant melanoma. Darrell S. Rigel, M.D. and colleagues from the Ronald O. Perelman Department of Dermatology at New York University School of Medicine say that, despite all of the advances in melanoma diagnosis, timely recognition, detection, and rapid treatment of melanoma remain critical.

Scientists unveil nanoparticle for photoacoustic imaging

Spotting a single cancerous cell that has broken free from a tumor and is traveling through the bloodstream to colonize a new organ might seem like finding a needle in a haystack. But a new imaging technique from the University of Washington is a first step toward making this possible.UW researchers have developed a multifunctional nanoparticle that eliminates the background noise, enabling a more precise form of medical imaging - essentially erasing the haystack, so the needle shines through. A successful demonstration with photoacoustic imaging was reported today (July 27) in the journal Nature Communications.

Report shows most men with low PSA undergo aggressive therapy

Study on treatment needs of prostate cancer patients with low level PSA

Controversy has long existed over the benefit of the prostate specific antigen (PSA) test used to screen for the presence of prostate cancer, and there has been little study to document the risk profile of men who have a PSA level at or below what is considered 'normal.' New research published in the latest edition of Archives of Internal Medicine (Vol. 170, No. 14) by a team of investigators at The Cancer Institute of New Jersey (CINJ), further explores this population. The findings show that most men with prostate cancer who tested below the normal PSA level and had low-risk disease nevertheless underwent aggressive treatment. CINJ is a Center of Excellence of UMDNJ-Robert Wood Johnson Medical School.
