Clinicians typically classify meningiomas—the most common type of brain tumor—into three grades, ranging from slow-growing to aggressive. But a new multi-institutional study suggests that appearances may be deceiving. If a tumor shows activity in a gene called telomerase reverse transcriptase, it tends to recur more quickly, even if it looks low-grade under the microscope.
Mayo Clinic researchers have developed a promising way to deliver treatment directly to cholangiocarcinoma tumors, a rare and aggressive bile duct cancer with limited treatment options, using milk-derived nanoparticles that act like guided delivery vehicles. The study points to a potential targeted genetic therapy designed to attack cancer cells while sparing healthy tissue.
