Exam 3 Flashcards
(173 cards)
Risk Factors for Heme Cancers
Genetic Damage (Ionizing Radiation)
Drug and Chemical Exposures (Benzenes and alkylating agents)
Genetics?
Viruses
Leukemia
Malignant disease of blood forming organs
WBC precursors proliferate in the bone arrow and lymphatic tissue
Leukemia Cell Types
Acute lymphocytic Leukemia
Acute Myeloid Leukemia
Chronic Lymphocytic Leukemia
Chronic Myeloid Leukemia
Acute Leukemia
Rapid Onset and Progression
100% Mortality within days/months if left untreated
Acute lymphocytic leukemia- most common in children, second most common in adults
Acute myeloid leukemia- most common in adults, second most common in children
Chronic Leukemia
Slower onset and progression
Survival weeks/years
-can sometimes change to acute
Leukemia S/Sx
Fatigue, Weakness
Enlarged lymph nodes
Bleeding, bruising, petechiae (Low platelets)
Infection that doesn’t heal, fever
Flu like symptoms that just won’t go away
Upper abdominal pain or feeling of fullness
Sometimes asymptomatic
(Bone marrow is busy making all the leukemia cells, no room to make the normal RBC and platelets. Thromobocytopenia and anemia are often common)
Leukemia Diagonsis
CBC= first thing they look at, blast cells in the WBC differential are NEVER normal, it means the patient has leukemia
Bone marrow aspiration and biopsy
LP for acute lymphocytic leukemia’s (have an affinity for the cerebrospinal fluid)
Leukemia Treatment
Chemo (Induction, consolidation, maintenance)
Radiation
Nursing Diagnoses
Risk for infection Risk for injury Activity intolerance Fatigue Impaired oral mucous membranes Impaired nutrition: less than body requirements Anxiety Risk for disturbed body image Risk for social isolation
Lymphoma Cell Types
Hodgkins (Reed-Sternberg Cell)
Non-Hodgkins (Small cell or large cell)
Hodgkins Lymphoma Signs and symptoms
- Painless enlargement of one or more lymph nodes on one side of the neck (Cervival, Supraclavicular, mediastinal)
- Medastinal Mass
- Pruritis (Severe Itching)
- Pain after drinking alcohol
- “B” symptoms (leads to more aggressive treatment) = Fever, Night sweats, Unintentional weight loss of > 10%
Lymphoma Diagnosis
Rule out of infection first, excisional biopsy of affected lymph node (Reed sternberg cell if present it is always diagnostic of lymphoma), Staging (CXR, CT of chest, abdomen, and pelvis, CBC, Platelets, ESR, bone marrow asipiration and bx)
Lymphoma Treatment
Goal: hodgkins- cure, NHL- control
Radiation therapy - used for early stage hodgkins
Chemotherapy - used for late stage hodgkins and NHL
Bone marrow trasnplant
Multiple Myeloma Histology
Malignancy of plasma cells (most mature forms of B-lymphocytes)
chronic disease with long term survivors but use to be fatal
Multiple Myeloma Epidemiology
Elderly (Mean age of dx is 68yo)
Occupation exposures (Farmers, petroleum workers, woodworkers, leather workers, nuclear industry workers.
Most common hematologic cancer in AA
Multiple Myeloma S/Sx
Bone pain (back or ribs, lytic lesions/osteoporosis on xray, fractures, hypercalcemia)
Renal failure
Fatigue (Anemia)
Headache, Blurred Vision
Multiple Myeloma Treatment
Considered incurable (Sx can be controlled sometimes allowing patients to live for several years, bone marrow transplants have increased the possibilities)
Chemo and RT
Bisphosphonates (Decrease pathological fractures) - aredia, zometa
Plasmapheresis (Remove blood from large chain immune complexes that are produced in cancer cells)
Thalidomide (Anti-myeloma properties)
Nursing Diagnoses for MM
Risk for infection
Risk for injury
Acute/Chronic Pain
Bone Marrow Transplant
Diseases (Leukemias, myeloma, myelodysplastic syndromes)
Eligibility
Types (Autologous (own cells), allogeneic (others cells), stem cell)
Bone Marrow Transplant Process
Bone marrow conditioning -Total body irradiation -Chemotherapy -Monoclonal Antibodies -The goal of the conditioning pase is to completely knock out the patients own bone marrow to allow the body to accept the donor bone marrow Bone marrow harvesting from donor Bone marrow infusion to recipient
Bone Marrow Transplant Supportive Care
- Transfusions (PRBC and platelets)
- Antibiotics (to prevent infection)
- Nutrition (Tube feeding, TPN)
- Strict protective isolation (neutropenic procautions)
Engraftment
When the donor marrow has engrafted into the patient;’s bone and begins producing cells
Uncontrollable Breast Cancer Risk Factors
Female gender Increasing Age Family hx Personal hx hx of bx: atypical hyperplasia Manarche before 12, menopause after 50 Bearing few or no children Having first child after 30 Not breast feeding
Breast Cancer Risk Factors
Increasing age and female sex
High hormone levels for a long period
(Estrogen promotes the growth of about two-thirds of breast cancers)
Family history is less significant, only 5-10% inherited mutations of the brca1and2 gene
Oral contraceptive use, prolonged post-menopausal hormone replacement therapy, and benign proliferative breast disease all increase the risk (Dutal hyperplasia, lobular hyperplasia, and papillomas)
