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.

Alnylam reports new results from investigational RNAi therapeutic programs

Alnylam Pharmaceuticals, Inc. (Nasdaq: ALNY), the leading RNAi therapeutics company, announced today preliminary results from its ongoing Phase 2 open-label extension (OLE) studies with patisiran and revusiran, both investigational RNAi therapeutics targeting transthyretin (TTR) for the treatment of hereditary TTR-mediated amyloidosis (hATTR amyloidosis).

Annual repeat CT scans can eliminate need for biopsy or surgery in NSNs

Annual low-dose computed-tomography (CT) screening can eliminate the need for biopsy or surgery in nonsolid lung nodules, according to a new study published online in the journal Radiology.

Endometrial scratching in women appears to increase chance of clinical pregnancy, live birth

There is a much disputed claim that "injury" to the lining of the uterus - whether inadvertent or deliberate - increases the chance of embryo implantation and thus the chance of pregnancy in certain groups of women having IVF.

Scientists reveal how new adult-born neurons evolve in olfactory bulb of mice

Scientists from the Institut Pasteur and the CNRS were able to make real-time observations over a period of several months that reveal how new adult-born neurons are formed and evolve in the olfactory bulb of mice.

New technique can help identify aggressive forms of DCIS

When a woman is diagnosed with the earliest stage of breast cancer, how aggressive should her treatment be? Will the non-invasive cancer become invasive? Or is it a slow-growing variety that will likely never be harmful?

Study shows low incidence of cancer in patients with large colorectal polyps

For the majority of patients with large or difficult to remove colorectal polyps (growths in the colon), the incidence of cancer is actually lower than previously thought, and using more advanced endoscopic techniques that spare the colon may be a better, safer alternative to a traditional operation in certain cases, according to study results published online in the Journal of the American College of Surgeons in advance of print publication.

Scientists create protein signatures for accurate diagnosis of prostate cancer

Researchers at the Ontario Institute for Cancer Research and University Health Network in Toronto, along with researchers at the Eastern Virginia Medical School, have created protein signatures that accurately diagnose prostate cancer and can distinguish between patients with aggressive versus non-aggressive disease using a simple urine sample.

Screening PSA levels in younger men could accurately predict future risk of prostate cancer

Prostate cancer screening with prostate-specific antigen (PSA) has been shown to reduce death and the spread of prostate cancer to other parts of the body, but the PSA test remains highly controversial as it frequently leads to over diagnosis and over treatment of men who may not be at risk.

MRI-guided focal laser ablation could be feasible, safe in prostate cancer patients

Prostate cancer patients may soon have a new option to treat their disease: laser heat. UCLA researchers have found that focal laser ablation - the precise application of heat via laser to a tumor - is both feasible and safe in men with intermediate risk prostate cancer.

Intrinsic subtyping of breast cancer can aid prognosis, treatment of tumor patients

Published in JAMA Oncology, Principal Investigator of Vall d´Hebron Institute of Oncology´s Translational Genomics Group, Team Leader of translational genomics and targeted therapeutics in solid tumors at the August Pi I Sunyer Biomedical Research Institute, and Head of Medical Oncology at the Hospital Clínic in Barcelona, Aleix Prat has led a study showing the intrinsic subtyping of breast cancer by means of a genomic test as the most important prognostic factor in advanced or metastatic hormone-sensitive breast cancer.
