1 Christie Asleson Hematology/Immunology

2 Chronic lymphocytic leukemia (CLL) is cancer of the blood and bone marrow. The term "chronic" comes from that it progresses more slowly than other types of leukemia. The term "lymphocytic" comes from the cells affected by the disease Overview

3 15,000 ppl each year in the United States It is the most common type of leukemia in adults. Most of those who get it are older than 55. Average age is 72 More common in men In some people can remain slow-growing for years and never need treatment. Overview

4 Lymphocytes evolve from immature cells called hematopoietic stem cells. Healthy lymphocytes evolve through their life cycle eventually die. In CLL, changes in the diseased cells prevent them from maturing properly. They have a longer life span. Over time, accumulate in the bone marrow and in the tissues of the lymphatic system Interfering with other immune system functions. How it develops

5 Many people with chronic lymphocytic leukemia have no symptoms. Those who do develop signs and symptoms may experience: Enlarged, but painless, lymph nodes Fatigue Feve r Nigh sweats t Weight loss Frequent infection Pain in the upper left portion of the abdomen, which may be caused by an enlarge spleen n Symptoms

6 Inherited or genetics, traits and exposure to cancer-causing agents in the environment. Relatives such as a parent, child, or sibling, with CLL Most cases its associated with specific gene mutation Risk Factors

7 Many types of tests are performed Tests can reveal abnormatlities in cells Amount of blood cells Changes in bone marrow Other factors in deciding the course of treatment Common Tests Used: Cytogenetic studies, Immunohisto-chemistry studies,Flow cytometry, and Molecular genetic studies Diagnosis

8 In the BloodBlood Test Complete Blood Count Low numbers of RBC Platelet levels low Normal WBC levels diminished Diagnosis cont.

9 Bone Marrow Aspirates & BiopsiesPhysical Examination Doctor will check: Lymph Nodes Spleen Liver First sign can be enlarged spleen or liver Bone Marrow biopsies- remove small peice of bone and marrow for examination Aspirate- Withdraw Small sample of liquid bone marrow Diagnosis cont.

10 Classify or stage each patients CLL according to how far the disease has progressed Rai System Stage 0 Stage I Stage II Stage III Stage IV Classification

11 No treatment yet that is considered a cure They are designed to slow progression of disease CLL develops very slowly Treatment

12 Radiation Therapy Used in rare cases Uses high-energy rays Destroys cancer cells Controls enlarged lymph nodes or spleen Treatment Cont.

13 Stem Cell Transplant For some patients Obtain stem cells by filtering from blood stream Then treated with high- dose of chemo. Doctors then transplant harvest stem cells Treatment Cont.

14 On going Care: People with CLL are likely to see their physician often to monitor the disease and to determine if it is progressing. These check-ups may include a physical exam, blood tests, bone marrow aspirates, biopsies, and radiographic studies. Treatment Cont.

15 Out come depends on a few things Change in DNA? Lymphocytes spread throughout bone marrow? The Stage of CLL Treatment helping or not? General Health Prognosis

16 5 year Survival rate Treatment and responses to treatment vary greatly The five-year relative CLL survival rates by race and sex were: ~ 74.3% for Caucasian men ~ 77.1% for Caucasian women ~53.8% for African American men ~ 62.2 %for African American women. Prognosis: What are the Survival Rates?
