Liquid Biopsy for CRC Screening May Not Be Ready for Prime Time
While screening for colorectal cancer (CRC) with a blood-based test would result in better outcomes than no screening at all, it would likely result in worse outcomes than currently available tests — while increasing costs — according to two modeling studies published in Gastroenterology. In the first, models suggested that compared with no screening at […]
Alzheimer’s Blood Test Predicts Who Might Benefit Most From Anti-Amyloid Drugs
Plasma phosphorylated tau 217 (p-tau217) outperformed p-tau181, p-tau231, and other blood-based biomarkers to identify which patients might benefit most from anti-amyloid Alzheimer’s drugs, a cohort study showed. Plasma p-tau217 helped rule out two groups who would not likely benefit: those who were amyloid-negative, and those who were amyloid-positive but had a high tau burden, reported […]
