Scientists are studying a new type of medicine made from circular RNA, which is RNA shaped like a circle instead of a line. Because of their circular shape, these medicines may stay in the body longer and work better than current RNA medicines. Researchers are testing these circular RNA medicines to treat cancer, immune system diseases, and rare diseases.
WHY IT MATTERSCircular RNA therapeutics could eventually offer longer-lasting treatments for rare diseases with fewer doses needed, but patients should know that claims about safety and effectiveness vary depending on how the medicine is made—there's no one-size-fits-all answer yet.

Scientists have discovered that certain rare genetic diseases are caused by mutations in genes that help cells copy their DNA. These genes normally produce proteins that untangle special twisted DNA structures called G-quadruplexes that get in the way during copying. When these proteins don't work properly, cells can't copy their DNA correctly, leading to problems like weak immune systems, slow growth, birth defects, and increased cancer risk.
WHY IT MATTERSUnderstanding which genes cause these G-quadruplex problems could help doctors diagnose patients with unexplained immunodeficiency, growth delays, or birth defects, and may eventually lead to targeted treatments for these currently untreatable conditions.

Doctors from around the world created a network called the International Neuroblastoma Risk Group to share information about neuroblastoma, a type of cancer that starts in nerve cells. They combined data from over 25,000 patients to help researchers understand the disease better and develop better treatment plans. This teamwork model shows how rare cancer research can be improved when hospitals and countries work together.
WHY IT MATTERSPatients with neuroblastoma now benefit from standardized treatment approaches and risk classifications developed through this international collaboration, which means more consistent and potentially better care regardless of where they receive treatment.

Researchers studied whether the amount of cancer in a patient's body before treatment affects how well two immunotherapy drugs work together. They looked at 722 patients with rare cancers who received nivolumab and ipilimumab (two drugs that help the immune system fight cancer). The study wanted to understand if patients with smaller tumors do better than those with larger tumors when treated with these combination drugs.
WHY IT MATTERSIf baseline tumor size predicts treatment response in rare cancers, doctors could better counsel patients on expected outcomes and identify which patients might benefit most from this dual immunotherapy approach before starting treatment.

Researchers reviewed 78 studies about early satiety (feeling full quickly after eating small amounts) in cancer patients. They found this symptom is common but often overlooked, and doctors don't have consistent ways to measure or describe it. The review shows there are big gaps in how we understand and treat this problem for cancer patients.
WHY IT MATTERSEarly satiety causes cancer patients to eat less and lose weight, which can weaken their ability to fight cancer and recover from treatment—but doctors rarely screen for or address this specific symptom.
