5 Cellular Review Evolve 3D Cellular Differentiation on web site

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 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. G 1, G 2, G 3, G 4 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? 1.High 2.Low

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 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

19 Oncology Cancer risks High alcohol consumption Low dietary vegetables and fiber (sources of antioxidants) Previous Viral infections: Hepatitis B or C Herpes viruses Papilloma viruses (HPV) Retrovirus HTLV –I

20 Oncology Types of cancer cells are named for their site of origin: Adenocarcinoma Carcinoma in situ (CIS) Squamous Basal cell Astrocytomas Melanomas Sarcomas Lymphomas

21 Oncology Symptoms of Cancer Cachexia – weight loss,unexplained Anorexia Anemia Impaired immune response Pain – when the cancer is large enough to compress nerves or organs Lymphadema – when the tumor blocks lymph or circulatory flow Motor or sensory deficits

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 Cancer statistics The top four cancers found in the United States are: Lung Breast Prostate Colorectal C

24 Oncology Cancer statistics Prostate cancer is the most common site of cancer and the 2 nd most common cause of cancer death in the United States The first cause of death in males is Lung Cancer

25 Oncology

26 Cancer statistics Lung cancer has annual new cases (incidence) of 173,770 people per year: 93,110 males and 80,660 females Annual mortality: 160,440 per year consisting of 92,000 males and 68,510 females

27 Oncology Cancer statistics 28% of all cancer deaths are due to lung cancer This is the leading cause of cancer death in both men and women There are more deaths from lung cancer than prostate, breast, and colorectal cancers combined

28 Oncology Cancer statistics Risks for lung cancer: Smoking (75-80% of cases) Occupational exposure Nutrition/Diet Genetic factors

29 Oncology Cancer statistics Prostate cancer is number two cause of cancer in men Breast Cancer is number two cause of cancer in women Most common non-malignant or non- fatal cancer is non-melanoma type skin cancers

30 Oncology The client says that she has heard that the origin of most cancers is “genetic”. What is the nurse’s best response? –A. “The development of most cancers is predetermined and not affected by environmental factors.” –B. “Cancers arise in cells that have been damaged,which may be in the genes”. –C. “ The majority of cancers are inherited” –D. “Cancer is more common among males than females.”

31 Oncology Lab tests for cancer Ultrasounds to determine size CT scan with contrast– the golden standard Genetic markers – BRCA 1 and BRCA 2 Tumor markers: CEA – general carcinogenic antigen PSA – prostate antigen CA-125 – ovarian CA-25,27 – breast HER 2 NEU – breast tissue needed

32 Oncology Lab tests for cancer Liver function tests CBC with diff Renal function tests PET scan – looks for metastasis using a radioactive glucose solution PT, PTT, Fibrinogen, Fibrin levels

33 Oncology Lab tests for cancer Pathology slide of tumor: (Should be kept for a period of years) Determines type of tumor Source of tumor Aggression of tumor – whether fast growing, differentiated, or non- differentiated Used to determine tumor growth factors and susceptibility to certain chemotherapies

34 Oncology Chemotherapy Prevention chemotherapy – for high risk patients, precancerous lesions, or history of cancer Antioxidants, vitamins Aldara cream 3x weekly for precancerous skin lesions Aspirin Protease inhibitors

35 Oncology Chemotherapy - typically started after surgical dissection of tumor, unless the tumor is non- operative Usually given by a long term venous access device, i.e. PICC line, implanted ports, or direct catheratization to the tumor. Chemotherapy is usually potent and horribly scarring on normal veins

36

37 Oncology Chemotherapy Biochemotherapy – used as in-patient or outpatient settings for cancer, MS, and viral treatments: Alpha interferon – (IFN)- Alpha 2a, Roferon, Intron-A- used for leukemias, AIDS, Hep-C Beta interferon – Beta 1b – used for renal carcinoma, melanoma, AIDS, MS, Hepatitis A, B

38 Oncology Chemotherapy/Biochemotherapy Interleukin I (IL-1) Interleukin 2 (IL-2), Proleukin– stimulates growth of T-cells and NK cytotoxic cells – used investigationally for melanoma in Stage II to Stage IV cases on a monthly basis with a 80% non- recurrence rate

39 Oncology Chemotherapy/Biochemotherapy Tumor necrosis factor (TNF) – selectively targets abnormal cells, in nature is produced by NK cells

40 Oncology Chemotherapy/Biochemotherapy Vaccines HPV vaccine for cervical cancer Melanoma vaccine - for stage II only at this time, or malignant melanoma

41 Oncology Chemotherapy/Biochemotherapy Monoclonal antibodies – used for treatment of cancer, rheumatoid arthritis, transplants, and other autoimmune diseases.

61 Oncology Radiation therapy All types of cells are injured or destroyed by concentrated radiation. Rapidly dividing cells are the most sensitive.

62 Oncology Radiation therapy Types : Gamma knife Local beam treatment Local seeding ARC – stereotactic Radioimmunotherapy Fractionation Total body irradiation Particle beam therapy, i.e. proton or neutron therapy

63 Oncology Radiation therapy side effects Side effects depend on the amount and area being irradiated Fatigue Nausea and vomiting Mild anemia Leukopenia Diarrhea Pain

64 Oncology Radiation therapy side effects: Erythema/burns Fatigue Pneumonitis Esophagitis Dysphasia (Please educate your patients on these as doctors are notoriously bad at pre-educating their patients).

65 What side effects of radiation therapy would you expect to see in a 48-year-old woman with breast cancer? 1.Debilitating fatigue 2.Mucositis 3.hair loss 4.nausea and vomiting

66 What are some of the educational issues for patients receiving radiation treatment 1.Burns 2.Anemia 3.Skin care 4.Diet 5.All of the above

67 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

68 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 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. Oncology

74 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/mm 3, 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.
