Patients in this study have been diagnosed with CLL or SLL and will be starting or have recently started treatment for CLL or SLL.
This observational study is research that aims to collect data over time on how a certain treatment is used and its effects, without any change to normal care. This means that routine clinical practice is followed. Any treatment given follows normal routine and is decided by you and your doctor. This study will not alter or interfere with the normal care patients receive in any way.
The purpose of this observational study is to build a registry that will provide information on regimens used to treat chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). Sometimes CLL and SLL can return (relapse) after treatment, or get worse (progress) during a course of treatment. If this happens, a new treatment is needed. The registry will collect the following information from patients regular care medical records for review and study: patients medical history and medications, patients cancer treatment and side effects, the results of patients regular care laboratory tests, and the results of cancer care and treatment procedures performed as part of patients regular care. The registry study will also collect information on how out-of-pocket costs impact cancer care and treatment. The registry that will be built from information gathered from this study can help doctors decide what to do in situations when a new treatment is needed. Importantly, they can also gather information to help doctors learn which treatments are most effective in these situations.
