Disease state overview
What is CLL/SLL?
CLL and SLL are cancers caused by abnormal B cells (also known as B lymphocytes). B cells are a type of white
blood cell
found in blood and bone marrow. When B cells develop normally, they help protect the body from infection and
disease.1,2
In CLL, cancer cells are found mostly in the blood and bone marrow. In SLL, cancer cells are found mostly in
the lymph
nodes and spleen. The treatment for CLL and SLL is very similar because they are both caused by abnormal B
cells.1

What is WM?
WM is a hematologic cancer that starts in B cells. The cancer cells in people with WM are similar to those of
multiple
myeloma and non-Hodgkin lymphoma.1
WM cells make large amounts of a certain type of antibody known as a macroglobulin. The buildup of this
antibody can
lead to many of the symptoms of WM, including excess bleeding, problems with vision, and nervous system
problems.1
WM cells grow mainly in the bone marrow, where they can crowd out normal blood cells. This may result in
anemia, a
weakened ability to fight infection, and increased bleeding and bruising.1

What is FL?
FL is a type of B-cell lymphoma, a form of non-Hodgkin lymphoma. It is a slow-growing cancer that may appear
in the
lymph nodes, bone marrow, and other organs. Symptoms of FL—such as swollen lymph nodes, fever, and drenching
night
sweats—are similar to those of non-Hodgkin lymphoma.1
Healthcare providers consider FL a chronic illness, as symptoms often subside after treatment and then come
back. This
cycle of remission-relapse-remission means people who have FL feel as if they’re never able to say they’re
“done” with
treatment.1

What is MCL?
MCL is a rare, aggressive form of non-Hodgkin lymphoma.
It is caused by the rapid growth and spread of cancerous
B cells.1
Patients with MCL generally present with enlarged lymph
nodes in the throat, liver, or gastrointestinal tract.1 Patients
may also have an enlarged spleen detected upon physical
examination.2
Because MCL is often diagnosed at a later stage of the
disease, it may spread to other sites in the body, including
the bone marrow, bloodstream, gastrointestinal tract, or
other sites not involving lymph nodes.3

What is MZL?
MZL comprises a group of slow-growing non-Hodgkin
lymphomas. MZL is a B-cell lymphoma that develops in a
type of lymphatic tissue called the marginal zone, which is
present in the blood, bone marrow, lymph nodes, spleen, or
other organs, and accounts for approximately 5% to 10% of all
cases of non-Hodgkin lymphoma.2
Extranodal MZL is the most common form of MZL. Other
types are nodal MZL and splenic MZL.2
MZL is more commonly diagnosed in people over the age
of 65. Because MZL is slow-growing, it may be years before
patients experience symptoms or the condition is detected.3
