  5. 5. Cellular Review• Evolve 3D Cellular Differentiation on web site
  6. 6. Oncology• Biology of abnormal cancer cells• They have continuous or inappropriate, usually faster growth or larger growth patterns• They have no specific morphology and often do not resemble their parent cells = anaplastic• They do not respond to signals for apoptosis = programmed cell death
  7. 7. Oncology• Biology of abnormal cancer cells• Have a large nuclear – cytoplasmic ratio; the nucleus may occupy most of the cell area• They lose some or all of their normal cell functions• They do not make fibronectin, and thus cannot connect easily and break off easily
  8. 8. Oncology• Biology of abnormal cancer cells• They are able to migrate throughout the body = metastasis• They invade other tissues and types of cells.• They are not controlled by contact• They have more or less chromosomes than the parent cells = aneuploid or a mutation of the genes
  9. 9. Oncology• Cancer development• Initiation – there are many theories as to when the genes in the cells are damaged, maybe in utero, from physical or chemical exposure, latent oncogenes, viruses, or a lack of suppressor genes from our parents, and at this point the cell is not dividing.
  10. 10. Oncology• Skin cells
  11. 11. Oncology• Cancer development• Promotion - the stage when the abnormal cell starts to divide, may be stimulated by environmental changes, hormones, drugs, or irritants
  12. 12. Oncology• Cancer development• Progression – the phase when the abnormal cells have continued to grow into a Primary tumor, may produce angiogenesis factors which supply blood and vascular nourishment to the tumor. The tumor may have subcolonies of cells with different genes and features
  13. 13. Oncology• Cancer development• Metastasis the movement of cancer cells into other organs of the body, thus creating new tumor sites.
  14. 14. Oncology• Cancer grading and staging• Cancer is graded upon the resemblance to normal cells = G(The higher the number, the worse the grade of cancer) i.e. G1, G2, G3, G4• Staging is based upon• the presence of a primary tumor = T• involvement in lymph nodes = N• and appearance of metastasis = M• Numbers of the stage range from x = none to 3 or 4 for each letter
  15. 15. Oncology• Is this a high grade or low grade cancer?• Case study Julie has a breast lump in her right breast, and has also found one in her right armpit. Biopsy and lumpectomy were performed. The tumor was graded G3, T2, N2, M1.
  16. 16. Is this a high grade or low grade cancer?1. High2. Low 0% 0% w gh Lo Hi
  17. 17. Oncology• Julie opted to have a lymphectomy of her right arm lymph nodes, and started radiation treatment right away. Her doctor also suggested that she start Adriamycin IV chemotherapy to get any cells that the radiation might miss.
  18. 18. Oncology• Cancer Risks• #1 = advancing age• #2 = smoking tobacco• Hormones – Prempro caused a substantial increase in breast cancer on the HERS trial• Genetic inheritance of oncogenes and autoimmune diseases• Environmental exposure• Excessive intake of dietary fats

  22. 22. Oncology• The 60 year old client with small cell lung cancer is concerned that his grown children also might develop the disease. What is the nurses best response? – A. “This disease is a random event and there is no way to prevent it.” – B. “Because this disease is inherited as a dominant trait, your children have a 50% risk for developing it.” – C. “Cigarette smoking is the main cause of this disease, and helping your children not to smoke will decrease their risk.” – D. “ Lung cancer can be avoided by decreasing dietary intake of fats and increasing the amount of regular aerobic exercise.”
  23. 23. Oncology• Cancer statistics• The top four cancers found in the United States are:• Lung• Breast C• Prostate• Colorectal

  66. 66. Oncology• Nursing interventions for radiation TX• Assess incidence and severity of side effects• Maximize radiation protection, all wastes will be radioactive if isotopes are injected• Shielding for staff
  67. 67. Oncology• Malignant Lymphomas – 2 types• Hodgkins Lymphoma – most common cancer in 10 to 20 year olds (young adults). Associated with an inflammatory process related to +EBV/mono infection.• Diagnosis: Classic Reed-Steinberg cell with two mirrored nuclei, CT scan• Symptoms: Extreme fatigue, enlarged lymph nodes that are painless. May progress to weight loss fevers, night sweats
  68. 68. Oncology• Malignant Lymphomas – 2 types• Hodgkins Lymphoma• Treatment – combined radiation and chemotherapy, stem cell transplants if resistant type or recurring• 85% curable• (90% in some institutions)
  69. 69. Oncology• Malignant Lymphomas – 2 types• Non-Hodgkins Lymphoma – 3 times more common than Hodgkin’s lymphoma, can either be T-cell lymphomas, or B-cell lymphomas• Can be low grade or high grade disease. B-cell lymphomas = 50% and usually are more aggressive tumors. Since they grow faster, they are also more sensitive to radiation and chemotherapy
  70. 70. Oncology• Malignant Lymphomas – 2 types• Non-Hodgkins Lymphoma• Diagnosis: bone marrow biopsy, CT scan, lymphoma panel with CD markers• Symptoms- adenopathy, spleenomegaly with vague abdominal pain, back pain, and since immunity B or T-cell function is affected- the patient is more prone to infections. Subcutaneous T-cell lymphoma is a classic discoid rash on the upper body and trunk that does not respond to steroids or creams.• NHL can progress rapidly to leukemia if untreated.
  71. 71. Oncology• Malignant Lymphomas – 2 types• Non-Hodgkins Lymphoma• Treatments: Monoclonal antibodies, chemotherapy with Fludara/Fludarabine, radiation therapy, and bone marrow implants
  72. 72. Oncology• Leukemia– hematopoeitic cancer of the stem cells. These stem cells proliferate into non-functional immature white cells.• More children get leukemia than any other type of cancer and it is the #1 cause of death in children.• Anyone can get leukemia at any age.
  73. 73. Oncology• Leukemia -4 types• Acute lymphoblastic leukemia (ALL)• Acute myelogenous leukemia (AML)• Chronic Lymphocytic leukemia (CLL)• Chronic myelogenous leukemia (CML)• Anagram – ALL AniMals are CLearLy CaMeLs
  74. 74. Oncology• Leukemia –ALL suspected cause is a T-cell virus (HTLV-1) – 85% is seen in children, 25% in adults 30-to-40 y.o.• Diagnosis: peripheral blood smear after abnormally high white count, bone marrow biopsy shows lymphoblasts >50%m may have decrease in platelets. Lumbar puncture to determine CSF involvement
  75. 75. Oncology• Leukemia –ALL• Symptoms – fatigue, anorexia, malaise, weight loss, bleeding, infections, headaches, adenopathy, spleenomegaly, gingival hypertrophy, hepatomegaly, bone or joint pain• Treatment: complete response is a bone marrow aspirate with < 5% blasts. Chemotherapy – vincristine, prednisone, danorubicin, methotrexate,• Maintenance therapy – 6 weeks of• 6-mercaptopurine and methotrexate low dose therapy
  76. 76. Oncology• Leukemia – AML – more common in patient’s with chromosomal genetic disorders, exposure to benzene or radiation. Use of alkylating agents for breast, ovarian, or myeloma are associated with a later malignancy of this type.• Symptoms- are like ALL with the additions of anemia, thrombocytopenia, visual disturbances, epistaxis (nosebleeds), headache with vomiting, dysphagia, papilladema, menorrhagia (lots more bleeding problems)
  77. 77. Oncology• Leukemia – AML• Diagnosis: peripheral blood smear shows Auer bodies (rods), platelets less than 20,000/mm3, bone marrow biopsy• Prognosis – poor prognosis if patient has already received radiation or chemotherapy, or has a WBC >100,000
  78. 78. Oncology• Leukemia – AML• Treatment: Cytaribine chemotherapy in combination therapy with Danorubicin or doxirubicin, works 65% of the time.• Bone marrow transplant or stem cell transplant.
  79. 79. Oncology• Leukemia – CLL – staged 0-5• chronic diseases have more mature cells, majority of CLL is B-cell proliferation – 95%. Only 5% are T- cells, more common in people with autoimmune diseases, i.e. SJogren’s, SLE, hemolytic anemia• Symptoms: skin and respiratory infections, fatigue, thrombocytopenia, anemia, spleenomegaly
  80. 80. Oncology• Leukemia – CLL• Diagnosis- peripheral blood smear, bone marrow biopsy• Treatments: Gleevac – drug of choice; chemotherapy in combinations, spleenectomy, radiation therapy to spleen, bone marrow transplant, stem cell transplants
  81. 81. Oncology• Leukemia – CML (last is the CaMeL) - More common after radiation exposure, benzene exposure, less common than the other types of leukemia, and occurs most often between 50-60 y.o.• Diagnosis: hallmark is the presence of the Philadelphia Chromosome, Chromosome #22 is missing part of the long arm which is translocated to Chromosome #9. This is present in 95% of those patients with CML.• WBC >100,000 with proliferation of all types of mature and immature white cells.• Bone marrow biopsy
  82. 82. OncologyLeukemia – CML• Symptoms: same as other leukemias with chronic fever, sternal tenderness and dyspnea – usually due to severe anemias• Treatments: chemotherapy with Bisulfan and hydroxurea, other combination chemos,• Interferon alpha 2b to suppress the expression of the Philadelphia chromosome.• Bone marrow transplant or stem cells
  83. 83. Oncology• Bone marrow and stem cell implantsNew treatments for:Acute myelogenous leukemias (AML)Acute lymphoblastic leukemias (ALL)Myelodysplasia syndromes (MDS)Chronic myelogenous leukemias that do not respond to chemotherapy (CML)Blast crisisPediatric acute leukemiasNon-Hodgkins lymphomaLarge B-Cell lymphomaMultiple myelomas
  84. 84. Bone marrow and stem cell implants
  85. 85. Oncology• Bone marrow and stem cell implants• Procedure= multiple punctures• Marrow acquisition from donor or when patient is in remission, or stem cells from umbilical blood of a matching sibling or family member• Marrow is filtered to purge tumor cells, fat and bone particles, then place in a blood bag for cryopreservation.
  86. 86. Oncology• Bone marrow and stem cell implantsPreparing Recipient:• Marrow recipient is given high dose chemotherapy alone or in combination with radiation to suppress immune system, open spaces in the marrow, and kill remaining cancer cells.• Bone marrow is thawed and infused through a central venous catheter
  87. 87. Oncology• Bone marrow and stem cell implantsPreparing Recipient:• Stem cells are infused after thawing• Post-procedure:• Patient is supported through the period of aplasia, 10 to 30 days, while in reverse isolation and on graft immunosuppressants,• Observed for signs of Graft-versus- host disease and/or infection
  88. 88. Oncology• The waves of the future:• Stem Cell Research• Oncogene therapy – now that cancer cells are being genetically tagged, we can tell which growth factors are present, and which enzymes turn off the gene. Soon all gene markers will have a pill that matches the enzyme, i.e. IRESSA is a tyramine kinase inhibitor, and stops the tumors growth that use tyramine kinase
  89. 89. Oncology• Stem Cell Induction – there are new drugs out for stem cell induction to immunosuppress the patient, even in deadly cancers, i.e. Multiple Myeloma. Recently, the combination of lenalidomide(Revalamid), bortezomib (Velcade) and dexamethasone produced a98% response rate in patients
  90. 90. Oncology• The waves of the future:• Cancer vaccines• Oncology is the science of cancer and treatment of all cancer patients. It is one of the most demanding and rewarding fields in medicine.• The future is open for a cure.
