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.

Study proposes a new, noninvasive way to detect kidney transplant rejection

Patients can spend up to six years waiting for a kidney transplant. Even when they do receive a transplant, up to 20 percent of patients will experience rejection.

Newly identified biomarker could predict response to immune checkpoint inhibitors

A team of Roswell Park Comprehensive Cancer Center researchers has identified a new biomarker that could predict response to immune checkpoint inhibitors (ICI) shortly after patients with non-small cell lung cancer (NSCLC) initiate therapy.

Researchers confirm a threshold value for non-invasive imaging biomarker

Breast cancer is the commonest fatal cancer in women. Early detection increases a woman's chances of recovery. Magnetic Resonance Imaging (MRI) is an accurate technique for detecting and classifying tumors in breast tissue.

New biomarker discovery could help guide treatment of active sarcoidosis

Low blood levels of immune cells called lymphocytes, in combination with higher levels of inflammation on PET/CT scans, are indicators of active sarcoidosis -- an inflammatory disease that attacks multiple organs, particularly the lungs and lymph nodes -- which disproportionately affects African Americans.

Long-term steroid treatment may not be necessary for kidney transplant patients

Long-term use of a medication used to treat kidney transplant patients may not be necessary in individuals with low-to-moderate risk of organ rejection, according to the results of a study led by a University of Cincinnati transplant researcher.

Combination therapy produces clinical benefit for early stage non-small cell lung cancer

The first randomized Phase II clinical trial to report on single and combined neoadjuvant immune checkpoint inhibitor therapy in stage I-III non-small cell lung cancer (NSCLC) found combination therapy produced a significant clinical benefit, as assessed by major pathologic response (MPR) rate, as well as enhanced tumor immune cell infiltration and immunological memory.

Liquid biopsy can help gauge the effectiveness of therapy for colorectal cancer

A new study from Washington University School of Medicine in St. Louis demonstrates that a liquid biopsy examining blood or urine can help gauge the effectiveness of therapy for colorectal cancer that has just begun to spread beyond the original tumor.

HKBU and CUHK jointly develop Spermine Risk Score for diagnosis of prostate cancer

Researchers from Hong Kong Baptist University and the Faculty of Medicine at The Chinese University of Hong Kong have jointly developed the Spermine Risk Score which, coupled with the use of a urine test, provides a non-invasive and more reliable method for the diagnosis of prostate cancer.

Biomarkers could help discriminate cancer therapy-associated kidney injury from other causes

A study by Mayo Clinic researchers published in Kidney International Reports finds that immune checkpoint inhibitors, may have negative consequences in some patients, including acute kidney inflammation, known as interstitial nephritis. Immune checkpoint inhibitors are used to treat cancer by stimulating the immune system to attack cancerous cells.

Combining PD-1 and VEGF inhibitors with chemotherapy can help control cholangiocarcinoma

Cholangiocarcinoma (CCA) is considered as a diverse group of epithelial cancers characterized by poor outcomes. Cholangiocarcinoma can be divided into three types according to the original position: Intrahepatic Cholangiocarcinoma (ICC), Perihilar Cholangiocarcinoma (PCC), and Distal Extrahepatic Tumors (DET).
