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.

Finding better treatments to eradicate infection caused by H. pylori bacterium

Helicobacter pylori (H. pylori) is one of the most common bacterial infections worldwide, affecting more than 40 % of the population and is one of the causes of digestive symptoms, such as epigastric discomfort, heaviness or bloating of the stomach, or of other more serious diseases, such as the development of gastric and duodenal ulcers, gastric lymphoma or gastric cancer.

Cell-free DNA employed to identify measurable residual disease

Researchers demonstrated that cell-free DNA from CSF could be employed to examine MRD in children treated for the brain tumor medulloblastoma.

High tumor-infiltrating lymphocytes could indicate a better chance of survival in esophageal cancer

Cancerous tumors are made up of many more components than just malignant cells from the tissue of origin. Immune cells can be recruited to the tumor site and form what is known as the tumor microenvironment.

Scientists show how skin T cells can damage other organs in stem cell transplant patients

More than 40,000 allogeneic hematopoietic stem cell transplants are carried out worldwide every year, mostly for patients suffering from leukemia or other diseases of the hematopoietic system.

Study discovers actionable DNA errors remain stable over time

A single analysis of the entire tumor DNA is mostly sufficient to identify all DNA errors that might be relevant for treating metastatic cancer.

Analyses of DNA tags may lead to better understanding of treatment approaches for cancers

Cell-free DNA (cfDNA) shed into the blood was discovered in the late 1940s but with rapid advances in genomics and computational analytics in just the past few years, researchers at Georgetown Lombardi Comprehensive Cancer Center now believe that studying tags, or modifications to this type of DNA, may lead to a better understanding of how to assess, and possibly modulate, treatment approaches for cancer and other diseases.

New method yields 10 times more accessible details of gene activity in individual cells

Researchers have devised a way to multiply by more than ten-fold the accessible details of gene activity in individual cells. It's a big leap in the effort to understand cancer development, brain function, immunity and other biological processes driven by the complex interactions of multitudes of different cell types.

Scientists are paving the way for cancer treatments with fewer side effects

In recent years, immunotherapy has revolutionized the field of cancer treatment. However, inflammatory reactions in healthy tissues frequently trigger side effects that can be serious and lead to the permanent discontinuation of treatment.

New nano-sized particles can improve the detection of tumors within the body

Nano-sized particles have been engineered in a new way to improve detection of tumors within the body and in biopsy tissue, a research team in Sweden reports.

Cells within the center of a tumor have the highest chance of spreading around the body

Researchers from the Francis Crick Institute, Royal Marsden, UCL and Cruces University Hospital have found that cells from different parts of kidney tumors behave differently, and surprisingly, cells within the center of a tumor are the most aggressive and have the highest chance of spreading around the body.

New technology efficiently detects gene mutation in blood with low error rate

Next-generation gene sequencing (NGS) technologies --in which millions of DNA molecules are simultaneously but individually analyzed-- theoretically provides researchers and clinicians the ability to noninvasively identify mutations in the blood stream.

Immune cells in cerebrospinal fluid could be biomarkers to predict immunotherapy response

Results from a study led by Joan Seoane, Director of Preclinical and Translational Research co-program at VHIO and ICREA Professor, show that immune cells accessing cerebrospinal fluid faithfully recapitulate the characteristics of cells identified in brain metastasis, and could therefore constitute novel biomarkers of response to immune-based therapies.
