This is a retrospective (take a look back at events that already have taken place), non-interventional, multicenter (when more than one hospital or medical school team work on a medical research study) study to review medical records of adult participants with a diagnosis of CLL, MM or NHL anytime since 01 January 2006. Only data available from clinical practice will be collected. All eligible participants at participating centers will be included regardless of participant's demographics, prior or current treatments for disease, or clinical outcome. The period of observation will span from 01 January 2006 through present, but all eligible participants must be followed for a minimum of 1 year, unless the participant died within that first year. Participant demographic parameters, standard therapies, treatment patterns and outcomes will be primarily quantified.
