3. INTRODUCTION Cancer of hematopoietic system are disorders that result from proliferation of malignant cells. Malignant cells are originated in bone marrow, thymus, and lymphatic tissue. B lood cells that originate in bone marrow are called hematopoietic cells. Blood cells that originate in lymph are called lymphoid cells. Leukemia (Cancer of Bone marrow) Lymphoma (Cancer of lymphoid tissue)

4. DEFINITION Leukemia is a malignant disease of the blood- forming organs. Leukemia is a malignant progressive disease in which the bone marrow & other blood forming organs produce increased no. of immature / abnormal leucocytes, these suppresses the production of normal blood cells, leading to anemia & other symptoms.

5. INCIDENCE (in India) About 3-4 per 100,000 population. These people account for 30% to 52% of all childhood cancers in males, and 19% to 52% in females .

6. ETIOLOGY AND RISK FACTORS The exact cause is unknown. Several factors are associated with leukemia include: 1. Genetic factor -A high incidence of acute leukemia & chronic lymphocytic leukemia is reported in certain families.

7. - Hereditary abnormalities associated with an increased incidence of leukemia are Down's syndrome, Fanconi's aplastic anemia, Trisomy of 13 (Patau's syndrome), etc. - Identical twins, fraternal twins, and siblings of children with leukemia are also at increased risk.

8. 2. Over-exposure to ionizing radiation and chemicals: Can become a major risk factor for development of leukemia, with disease developing years after initial exposure. Alkylating agents used to treat other cancers, especially in combination with radiation therapy, increase a person's risk of leukemia. Workers exposed to chemical agents, such as benzene (an aromatic hydrocarbon), are at a much higher risk.

9. 3. Congenital abnormalities: - Down's syndrome. 4 . The presence of: -Primary immunodeficiency -Infection with the Human T-cell Leukemia Virus Type-1 (HTLV-1).

10. PATHOPHYSIOLOGY The pathophysiology of leukemia involves: Abnormal proliferation of leukocytes Failure of leukocytes to mature Metabolic complications Abnormal leukocytes cannot perform the primary function Abnormal cells crowd the bone marrow, lymph nodes, and spleen Infection and bleeding are two common perils

11. TYPES There are 4 major types on the basis of acute versus chronic, the term acute and chronic refers to cell maturity and nature of disease onset: Acute lymphocytic leukemia. Acute myelogenous leukemia. Chronic lymphocytic leukemia. Chronic myelogenous leukemia.

12. Primary diff. b/w the four types is the rate of progression and where the cancer develops. Chronic leukemia cells do not mature all the way, so they are not as capable of defending against infections as normal lymphocytes. Acute leukemia cells begin to replicate before any immune functions have developed.

13. 1. Acute lymphocytic leukemia: Most common type of leukemia in children, andaccounts for 15% in adults. In this type , immature lymphocytes proliferatein bone marrow. most are of B-cell origin. Age of onset: - Before 14 year of age . - peak incidence in b/w 2-9 years of age, - and in older adults

14. Clinical manifestations: Fever, pale skin, bleeding, anorexia, fatigue and weakness. Bone , joint and abdominal pain. Generalized lymphadenopathy, infection, weight loss. Hepatomegaly mouth sores, splenomegaly, headache. Increased ICP (nausea, vomiting, lethargy, cranial nerve dysfunction)

15. Diagnostic evaluation: - Low RBC count, Hb , low platelet count. - Low, or high WBC count. - Transverse lines of rarefaction at ends ofmetaphysis of long bones on X-rays. - Hyper cellular bone - marrow with lymphoblast. - Lymphoblast also possible in CSF. - Presence of Philadelphia chromosomes (20-25% cases).

16. 2. ACUTE MYELOGENOUS LEUKEMIA: This type represents only 1/4th of all leukemias , in which 85% of this type in adults. It is characterized by uncontrolled proliferation of myeloblasts , precursors of granulocytes. There is hyperplasia of bone marrow.

17. AGE OF ONSET: - Its onset is often abrupt & dramatic, a patient may have serious infections and abnormal bleeding from the onset of disease. - Increase in incidence with advancing age, peakincidence b/w 60 and 70 year of age.

18. CLINICAL MANIFESTATIONS Fatigue Weakness Headache Mouth anemia, bleeding, fever, infection ,sores, sternal tenderness - Gingival hyperplasia, minimal hepato-splenomegaly & lymphadenopathy

19. Diagnostic evaluation: Low RBC count, Hb , Low platelet count, low to high WBC count with myeloblasts High LDH, greatly hypercellular bone marrow with myeloblasts .

20. 3. CHRONIC LYMPHOCYTIC LEUKEMIA: It is most common type in adults. It is characterized by production and accumulation of functionally inactive but long. lived, small, mature-appearing lymphocytes. The type of lymphocytes involved is usually B -cell. The lymphocytes infiltrate the organ.

21. Lymphadenopathy is present throughout the body, and there is an increased incidence of infection because of T-cell deficiencies or hypogammaglobulinemia . Pressure on nerves from enlarged lymph nodes cause pain and even paralysis . • Onset: - 50-70 years of age, rare below 30 year of age.

22. . Clinical manifestations: - No symptoms frequently. - Disease is often detected during examination for unrelated conditions, chronic fatigue, anorexia. - Splenomegaly & lymphadenopathy. - Hepatomegaly, may progress to fever, night sweats, weight loss.

23. Diagnostic evaluation: - Mild anemia and thrombocytopenia with diseaseprogression ; total WBC count >100,000/micro L. - Hemolytic anemia (4-11%). - Thrombocytopenia purpura (2-4%). - Hypogammaglobulinemia .

24. 4. CHRONIC MYELOGENOUS LEUKEMIA It is caused by excessive development of mature neoplastic granulocytes in the bone marrow. The excess neoplastic granulocytes move into peripheral blood in massive no. and ultimately infiltrate the liver & spleen . These cells contain a distinctive cytogenetic abnormality, the Philadelphia chromosomes, which serves as a disease marker and results from translocation of genetic material between chromosomes 9 and 22.

25. . Age of onset: - 25 to 60 year of age, peak incidence around 45 year of age . Clinical manifestations: No symptoms are seen earlier. Fatigue and weakness, fever, sternal tenderness, weight loss, joint pain, pain in bone, massive splenomegaly, increase in sweating, to 60 year of age, peak incidence around 45 year of age.

26. Diagnostic findings: - Low RBC count, Hb , Hct . - High platelet count early, lower count later. - Presence of Philadelphia chromosomes in 90% Of patients.

27. CLINICAL MANIFESTATION • Clinical features of leukemia relate to the problems caused by bone marrow failure andformation of leukemic infiltrates •As leukemia progresses: Fewer normal blood cells are produced - Abnormal WSC continue to accumulate ( don'tgo through apoptosis)

28. - The leukemic cells infiltrate the patient's organs, leading to problems such as splenomegaly, hepatomegaly , lymphadenopathy, bone pain, meningeal irritation and oral lesions. - Solid masses resulting from collection of leukemic cells called chlormas can also occur.

29. DIAGNOSTIC EVALUATION • A history collection. Physical examination. Peripheral blood evaluation ( WBC & platelets count) • Bone marrow examination (sampling from hipbone). • Lumbar puncture and CT scan are done to determine the presence of leukemic cells outside of blood & bone marrow.

30. MANAGEMENT PHARMACOLOGICAL MANAGEMENT It includes the chemotherapy, which is a major form of treatment for leukemia. This drug treatment use chemicals to kill leukemia cells. This can be a drug or a combination of drugs. these can be in form of pill or IV injection .

44. • NURSING MANAGEMENT: >Assessment: > Nursing diagnosis: 1.Ineffective protection / risk for infection related to neutropenia or leukocytosis secondary to leukemia or treatment. Intervention: •Assessing client. •handwashing techniques. • Client isolation.

45. Low bacteria diet (excluding fruits & vegetables). Daily bath with antibacterial soap. Maintain oral hygiene. Daily stool softeners (to reduce anal fissures). Perineal cleansing for every bowel movement. Avoid rectal suppositories & rectal thermometer. Temperature should be taken (oral, axilla, tympanic) every 4 hourly, report if more than 100.5 °F or lower than 97.5°F ( because fever is only the symptom in neutropenic client).

46. 2. Decreased cardiac output related to thrombocytopenia secondary to either leukemia or treatment . INTERVENTION: • Institute bleeding precautions: - Provide a soft toothbrush for oral hygiene - Avoid commercial mouthwash containing alcohol. - Avoid blowing or picking nose, straining at bowel movements, douching or using tampons, using razorsduring neutropenic phase .

47. Don't administer IM/SC inj. Do not insert rectal suppository. Avoid aspirin containing drugs. Avoid urinary catheterization, if needed then only lesser sized. Avoid mucosal trauma during suctioning. Remove all sharp objects around client. Use pressure reducing mattress, proper change the position Use only paper tape ,avoid strong adhesive (can cause skin adhesions).

48. 3. Fatigue related to side effects of treatments, low haemoglobin levels, pain, lack of sleep. INTERVENTION: • Assess for anemia. • Assess for physical, mental and treatment related causes of fatigue. • Encourage exercise to maintain strength. • Allow for rest.

49. 4. imbalanced nutrition less than body requirements related to anorexia, pain or fatigue. INTERVENTION : • Administer anti-emetics. (before meal/ drinking). • Administer local IV analgesics. • Provide high Cho meals & oral supplements .Weight daily. • If client can not tolerate oral foods for an extended period, begin TPN, as ordered. • Monitor intake.

50. 5. Disturbed body image resulting from alopecia, weight loss and fatigue. Intervention: • Before treatment, inform client about the potential for hair loss over entire body. •Encourage use of hats, etc as desired. • Explain the temporary nature of alopecia. • Encourage him to balance rest with exercise to maintain muscle tone without developing severe fatigue.

51. SUMMARY LEUKEMIA is a blood cancer caused by a rise in the number of WBC’s in your body. Those white blood cells crowd out the red blood cells and platelets that your body needs to be healthy. Extra white blood cells don’t work right . Types : 1. acute lymphocytic leukemia(ALL) , 2. acute myelogenous leukemia(AML), 3. chronic lymphocytic leukemia(CLL), chronic myelogenous leukemia(CML) Caused by smoke, radiation, chemotherapy, family history, down syndrome

52. Cont… Diagnosed by: blood test , bone marrow biopsy, spinal tap, imaging test Treatment: radiation , biologic therapy, stem cell transplant.
