WhiMSICAL is a global clinical trial inviting Waldenstrom's Macroglobulinemia (WM) patients to provide their clinical data which will help advance current knowledge and understanding of this disease. CART-WHEEL (Center for Analysis of Rare Tumors) is a database designed to address some of the barriers facing effective research into rare cancers. Show your support and spread the word. If you are a WM patient or know of one, send them to www.cart-wheel.org and complete a simple survey.
