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
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
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
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
Oncology Skin cells
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
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
Oncology Cancer development Metastasis
the movement of cancer cells into other organs of the body, thus creating new tumor sites.
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
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
Is this a high grade or low grade cancer?
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
Oncology Cancer Risks #1 = advancing age #2 = smoking tobacco

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

Oncology Malignant Lymphomas – 2 types
Hodgkin's 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
69
Oncology Malignant Lymphomas – 2 types Hodgkin's Lymphoma
Treatment – combined radiation and chemotherapy, stem cell transplants if resistant type or recurring 85% curable (90% in some institutions)
70
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
71
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.
72
Oncology Malignant Lymphomas – 2 types Non-Hodgkins Lymphoma
Treatments: Monoclonal antibodies, chemotherapy with Fludara/Fludarabine, radiation therapy, and bone marrow implants
73
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.
74
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
75
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
76
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
77
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)
78
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
79
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.
80
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
81
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
82
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 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
83
Oncology Leukemia – 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
84
Oncology Bone marrow and stem cell implants New treatments for:
Acute myelogenous leukemias (AML) Acute lymphoblastic leukemias (ALL) Myelodysplasia syndromes (MDS) Chronic myelogenous leukemias that do not respond to chemotherapy (CML) Blast crisis Pediatric acute leukemias Non-Hodgkins lymphoma Large B-Cell lymphoma Multiple myelomas
85
Bone marrow and stem cell implants
86
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.
87
Oncology Bone marrow and stem cell implants Preparing 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
88
Oncology Bone marrow and stem cell implants Preparing 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
89
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
90
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 a 98% response rate in patients
91
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.
