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.

New liquid biopsy chip captures circulating tumor cells with greater sensitivity

Researchers at Worcester Polytechnic Institute have developed a chip made of carbon nanotubes that can capture circulating tumor cells of all sizes and types, and can do so with far greater sensitivity than existing technologies.

Adjuvant radiotherapy may help treat locally advanced prostate cancer

Some 5,400 men are diagnosed with prostate cancer in Finland every year. Although in most cases prostate cancer can be cured, approximately 900 men every year die of it.

An unexpected developmental hierarchy in a rare disease affecting young children

Langerhans cell histiocytosis is a rare disease affecting primarily young children. While LCH may heal by itself without treatment in some patients, others require intensive chemotherapy and suffer from long-term consequences, or may even succumb to the disease.

Fat cells may be egging on melanoma cells to become more aggressive

A new study has shown that fat cells could be implicated in the transformation of the melanoma cells in the skin into highly malignant cells that spread to the different organs of the body. A team from the Tel Aviv University, led by Prof. Carmit Levy and Dr. Tamar Golan of the Department of Human Genetics and Biochemistry at TAU's Sackler School of Medicine published their findings in the journal Science Signaling this week.

DCCNet demonstrates use of Parsortix system for single cell CTC analysis

ANGLE plc, a world-leading liquid biopsy company, is pleased to announce that one of its leading customers, the Disseminated Cancer Cell Network, Duesseldorf, an interdisciplinary team of cancer researchers and clinicians, has published new results in a peer-reviewed journal of work done to develop a “robust, reliable and cost-efficient workflow” for enrichment of single circulating tumor cells.

Diet and nutrition influence microbiome in colonic mucosa

Diet is important in maintaining human health, but its underlying mechanism is not yet fully understood. Now, a team of researchers sheds light on the connection of diet and health, and it has something to do with the microbiome composition in human colonic mucosa.

Using machine learning algorithm to accurately diagnose breast cancer

Breast cancer is the leading cause of cancer-related death among women. It is also difficult to diagnose. Nearly one in 10 cancers is misdiagnosed as not cancerous, meaning that a patient can lose critical treatment time.

Prevalence of anal cancer precursors is higher in women living with HIV than previously reported

The prevalence of anal high-grade squamous intraepithelial lesions (HSIL), which precede anal cancer, is much higher in women living with HIV than previously reported, a multi-site, national study involving hundreds of patients has found.

Strengthening muscles may be better way to protect from health hazards rather than losing fat

Focusing on strengthening our muscles rather than losing fat may be a better way to protect ourselves from weight-related hazards like diabetes and cardiovascular disease, investigators say.

Collagen powder found to be effective in wound closure

Collagen powder is just as effective in managing skin biopsy wounds as primary closure with non-absorbable sutures, according to a first-of-its-kind study published in the Journal of Drugs in Dermatology by a team of physician researchers at the George Washington University.

Common cold virus strain could be a breakthrough in bladder cancer treatment

Scientists in the UK have found a new way to treat bladder cancer, using a strain of one of the viruses that cause the common cold. The virus is called Coxsackie virus CVA21, and it was found to be oncolytic, or tumor-destroying.

IU-connected startup working to enable precision medicine for mental health issues, chronic pain

A new startup company founded on science developed at Indiana University is working to enable precision medicine by commercializing the first objective tests for mental health issues, including suicide risk, post-traumatic stress disorder and depression, and for pain, all of which historically have been difficult to measure for patients and health care providers alike.

Physicians trained in dermatoscopy can improve odds for early detection of melanoma

Primary care physicians trained in dermatoscopy can improve odds for early detection of melanoma while reducing the need for invasive biopsies, according to a study in The Journal of the American Osteopathic Association.

New biomarker in urine can help detect aggressive prostate cancer

A team of researchers from UCLA and the University of Toronto have identified a new biomarker found in urine that can help detect aggressive prostate cancer, potentially saving hundreds of thousands of men each year from undergoing unnecessary surgeries and radiotherapy treatments.

New treatment method for glioblastoma shows indication of benefit

Glioblastoma is an aggressive brain tumour that usually occurs in late adulthood. Just two years after diagnosis, only 13.6% of patients are still alive. Standard treatment consists of surgery, followed by radiation and chemotherapy.

New prostate cancer test could bring an end to unnecessary biopsies

Researchers have developed a new urine test to diagnose aggressive forms of prostate cancer, which could mean an end to the unnecessary treatment of men with non-aggressive cancers.

PET/CT can aid in earlier diagnosis and treatment assessment of tuberculosis

Research presented at the Society of Nuclear Medicine and Molecular Imaging's 2019 Annual Meeting shows that molecular imaging with 18F-FDG positron emission tomography/computed tomography can evaluate tuberculosis at the molecular level, effectively identifying diseased areas and guiding treatment for patients.
