Circulating Tumor DNA Detects Early Melanoma Growth

According to the National Cancer Institute, there were 91,270 new cases of melanoma in 2018, making up more than 5% of all new cancer cases. There were 9,320 estimated deaths in 2018, and 91.8% of patients survive five years or longer. More...

Methylation-Based Liquid Biopsy Test Detects Liver Cancer

Hepatocellular carcinoma (HCC) represents about 75% of liver cancers in the USA and already has well-established screening criteria focused largely on individuals with cirrhosis, who are screened every six months using ultrasound with or without blood testing for alpha- fetoprotein, according to guidelines. More...

Liquid Biopsy Detects Cancer across Multiple Biomarkers

Although biomarker-directed therapy is in its infancy in prostate cancer compared to some other tumor types, there is a great need for predictive biomarker testing, and great interest in noninvasive methods. However, comprehensive analysis of patients' cell-free DNA has been limited to date. More...

Genes Identified That Predispose People to Chronic Kidney Disease

Chronic kidney disease (CKD) affects 10% to 15% of the population worldwide and is now recognized as the most rapidly increasing contributor to global burden of disease. The costs related to CKD and end-stage renal disease (the terminal manifestation of CKD) are an enormous burden for all healthcare systems around the world. More...

Levels of IgA Nephropathy Associated with Disease Severity

IgA nephropathy (IgAN) is the most common cause of primary glomerulonephritis. IgAN is associated with a poor prognosis, about 20% to 40% of patients with IgAN progress slowly to end-stage renal failure 20 to 25 years after diagnosis. More...

Sensitive Tumor Detection Uses Cell-Free DNA Methylomes

A combination of "liquid biopsy," epigenetic alterations and machine learning has been used to develop a blood test to detect and classify cancer at its earliest stages. The method holds promise of being able to find cancer earlier when it is more easily treated and long before symptoms ever appear. More...

Biomarker Found for Prostate Cancer Treatment Response

Prostate cancer is one of the most common cancers in males and has one of the highest five-year survival rate when diagnosed in the localized stage. When diagnosed in the advanced stage or when a localized tumor relapses after the initial local treatment, the usual procedure is to fight it using male hormone (androgen) deprivation therapy.
