Oncology and Such Flashcards
What is the pathogenesis of cancer?
- uncontrolled growth and spread of abnormal cells
- starts with some carcinogen, oncogene
- changes in a single cell: altered cell DNA, normal controls on cell growth are ineffective resulting in rapid cellular proliferation
- cells keep mutating-why we see in elderly
- cancer-relevant genes discovered
What group are most cancers in?
70% are in 65 years old and up
What are oncology risk factors?
- advancing age
- exposure to viruses: HPV
- lifestyle or personal behaviors
- geographic location and environment
- ethnicity, herditary
- stress
- precancerous lesions
- exposure to hormones
- socioeconomic status
- occupation: fumes, etc
- inflammatory bowel disease: increased risk of cancer
When do cancers usually develop symptoms?
when they metastasize?
What cancers have screening?
breast, tongue, mouth, colon, rectum, cervix, prostate, testis, skin
Tell me about tumors/neoplasms
- benign or malignant
- -better survival rate; metastases
- carcinoma in situ: encapsulated, can be removed easily
- primarily-cells that are local to the structure: determines the type of treatment
- secondary-result of metastasized cancer cells from the primary site
Metastases
cells break away from the primary tumor and travel via the blood or lymphatic system where they infiltrate organ tissue and grow in a new tumor
dysplasia
disorganization of cells
-Pap smear
Hyperplasia
abnormal growth of abnormal cells-onset of tumor
differentiation
don’t look like original cells
-stage four, poor prognosis
Tumor types
benign
- non-invasive
- non-metastatic: invasive (basal cell-skin cancer), doesn’t metastasize to another organ
malignant
- invasive
- metastatic (carcinoma, sarcoma): malignant tumor made up of epithelial cells tending to infiltrate surrounding tissue and metastasize (85% of all cancers)
Classifications of Neoplasm
- basis of cell type
- tissue of origin
- degree of differentiation: biopsy
- anatomic site
- benign vs. malignant

BRAIN BREAK
classifications on page 52 slide 2
acute vs chronic leukemia
- acute: accumulation of immature lymphoid or myeloid cells in the bone marrow and peripheral blood

What are the 3 main leukemia symptoms?
- anemia
- infection
- bleeding tendencies-thrombocytopenia
AML: who, tx, survival
- acute myelogenous
- most common in adults; difficult to treat in children

- long term survival 60%, 75% with complete remission will relapse in 2 years
CML: what, signs, tx, outcomes
- chronic myelogenous
- philadelphia chromosome
- fatigue, fever, night sweats, splenomegaly

Childhood cancer survivors: brain function
- increased risk with brain tumors or ALL
- brain cells in the early years grow very quickly, making them very sensitive to radiation
- cognitive impairments: lower IQ, problems with memory and attention, poor hand-eye coordination, slower development over time,behavioral problems; non-verbal skills like math more likely to be affected
- seizures & headaches
- effects on pituitary gland: poor appetite, fatigue, listlessness, cold inolerance
Childhood cancer survivors:vision
- most common in retinoblastomas
- radiation can cause cataracts, slow bone growth causing changes in eye shape as child grows
- chemotoxic to eye and may lead to blurred vision, double vision, glaucoma
- children with stem cell transplants may be at higher risk for eye problems if they develop chronic graft-versus-host disease
- other late effects: dry eye, watery eye, discolored sclera, poor vision, light sensitivity, poor night vision, tumors on the eyelid, drooping eyelid
Childhood cancer survivors: hearing
- chemo, radiation, and antibiotics may cause hearing loss (especially high-pitched sounds, higher risk in children who are young at the time of treatment)

- trouble with background noise
Childhood cancer survivors: growth
- delayed growth
- radiation: head and neck can affect overall growth and development by damaging the pituitary
- may affect bones, height, full maturity
- very young children most likely to be effective
- growth hormone may reverse some effects when pituitary gland is damaged
Childhood cancer survivors: thyroid
- affected by radiation or surgery to the head and neck or some stem cell transplants
- affect growht, development, metabolism
- most often hypothyroidism-extreme fatigue, dry skin, unexplained weight gain, constipation, slowed bone growth, thinning hair
- hyperthyroidism less likely but possible
- greater risk for thyroid nodules
Childhood cancer survivors: muscle and bone
- bone, soft tissue, muscle and blood vessels sensitive to radiation during times of rapid growth (young children and growing children at greatest risk)
- late effects: unequal growth, bone pain, joint stiffness, changes in gait, increase susceptibility to fractures, decreased calcium
- high doses of chemo or corticosteroids to treat leukemia or lymphoma can cause osteonecrosis
- gait changes, proximal muscle weakness
Childhood cancer survivors: sexual development- males
- radiation and chemo can reduce sperm production
- treatments that alter testosterone can lead to failure to complete puberty, delayed or accelerated puberty, decreased sexual desire or impotence
Childhood cancer survivors: sexual development- females
- high doses of chemo can damage ovaries causing changes in menstrual cycle-more at risk after puberty
- at risk for early menopause and reduced fertility-early menopause increases risk for OP and coronary heart disease
- increased risk for miscarriage, low birght weight, premature birth
Childhood cancer survivors: heart and lungs
- increased cardiac mortality in adult survivors
- chemo: damage to heart muscle, dysrhythmias, decreased left ventricular function associated with reduced contractility and excessive afterload; fibrosis and pneumonitis
- radiation: CHF, dysrhythmias, heard valve abnormalities, and damage to coronary arteries; decrease lung volume, SOB, constant cough, pulmonary fibrosis, pneumonitis, increased risk of infections, increased risk for lung cancer, decreased chest wall growth
- heart transplants
- increased SOB, increased arhythmias-red flags
- watch activity levels and changes in CV response
- more likely to have a heart attack
Childhood cancer survivors: teeth
- mostly effects from chemo or radiation in children who were treated before the age of 5
- include small teeth, missing teeth or delayed development, abnormal tooth enamel, increased risk of cavities, sensitivity to hot or cold, gum disease, short roots
- salivary glands affected: decreased saliva and dry mouth
- malnourished
- dry mouth: increased risk of fungal infections in mouth->sores
- -stay hydrated
Childhood cancer survivors: obesity
- ALL and brain tumors at greatest risk due to chronic steroid therapy and cranial radiation
- more likely to have diabetes type 2
- development of metabolic syndrome: obesity, HTN, dyslipidemia or impaired glucose tolerance
- -increased cholesterol
Childhood cancer survivors: second cancers

Does everyone exposed to HIV get it? Do they all get AIDs?
no and no
Pathogenesis of HIV
- progressive destruction of Tcell (cell mediated immunity)
- destroys and inactivates T4 lymphocytes (CD4 cells); macrophages and B cells also affected
- -every system relies on CD4 cells
- migrates from serum into tissue to blood destroying lymphocytes
- cell containing CD4 antigen serve as a receptor during DNA replication
- HIV contains reverse transcriptase
- -HIV viruses take over CD4; dropping CD4 determines tx, when they get symptoms
- high mutation rate
What is the first sign of HIV/AIDS usually?
- worst flu they’ve ever had, reoccuring flus or pneumonias
- infection they can’t get rid of
- fluctuations in CD4/T cell counts
What are symptoms in the early stages? Middle? Late?
- skin infections, fatigue, night sweats, weight loss
- mild symptoms increase
- pneumocystis pneumonia, CMV, neurologic (coma), cancer
What are five symptoms of aids?
- fatigue, depression
- frequent recurrent infections (enlarged lymph glands, joint pain)
- diarrhea (malnutrition, weight loss)
- Kaposi’s sarcoma (w/ it and under 60-get tested)
- altered neurologic function
What do infections look like for HIV patients?
1 or 3 forms
- immunodeficiency with unusual malignancies and opportunistic infections (25-40% have Hep C)
- autoimmunity such as RA, pneumonitis and production of autoimmune antibodies
- neurologic dysfunction, AIDs, dementia, HIV encephalopathy and peripheral neuropathies
What is the difference between acute infection and clinical latency and AIDS?
- acute: CD4>500
- latency: CD4=200-500
- AIDS: CD4=<200
