Ch. 23 Pediatric Cancer

the three main consequences of leukemia: s/s

anemia - bone pain (limping), lethargy, pallor, anorexia infection - fever, lymphadenopathy, abnormal WBC count, unresponsive to antibiotics bleeding - bruising purpura, nosebleeds

non-hodgkin's lymphoma

cause - incidence increases with age only 2% in children - uknown risk factors - immune system dysfunction s/s - may develop in any lymph system organ (spleen, tonsils, intestines, thymus gland) - pain or swelling - enlarged lymph odes - cervical, axillary, or inguinal area - respiratory probs - weight loss, fever, night sweats diagnosis - x-rays, labs, lymph node biopsy prognosis - rapid disease progression, lower long term survival rates than hodgkins treatment - chemo, radiation, stem cell transplant, targeted drugs, immunotherapy

hodgkin's disease/lymphoma

cause - more common in teens and young adults (15-39) - unknown, may be r/t viral infection - more common in those with HIV, epstein-barr, exposure to ionizing radiation, fam hx - possibly due to pesticides/herbicides s/s - painless, non-tender, enlarged lymph nodes - cervical, supraclavicular, inguinal, or axillary mediastinal mass - fever, weight loss, night sweats, cough, abdominal discomfort, nausea, slow insidious progression diagnosis - clinical manifestations and lymph node biopsy - presence of reed-sternburg cells, large multi-nucleated cells treatment - chemo with/without radiation prognosis - long term survival rate excellent considerations - address fatigue, pain, monitor for infection/fever

considerations/treatment/interventions for BOTH bone tumors

diagnosis - radiology test and biopsies treatment - surgery (removal or tumor or amputate), radiation, chemo, targeted therapy, cyrosurgery considerations - cure rates around 75-85% depending on severity for both, watch long term side effects such as infertility, organ damage, and mental health issues - may metastisize interventions - phantom limb pain - chemo affects - monitor PT progress - prosthesis care - stress importance to follow up

brain tumors

patho - a tumor that arises from any cell within the cranium - life threatening even if non-cancerous s/s - increased head size and ICP - HA first thing in AM - vomiting (^ICP) - sluggish pupils, dilated, or unequal - weak hand grasp diagnostics - MRI, CT, LP, PET scan, brain tissue removal during surgery to diagnose type of tumor treatment - surgery - chemo - radiation - steroids (dexamethasone) - anticonvulsants (fosphenytoin and phenytoin) interventions - monitor for seizures - assess pupils, neuro checks, neuro status can change rapidly - elevate HOB 30 degrees - meds to prevent vomiting and ^ICP

wilm's tumor

patho - malignant renal tumor - peak age at diagnosis 2-5years - in small children large lump in abdomen may first be noticed by parents when dressing or bathing s/s - usually painless - hematuria, HTN, pain infrequent unless tumor ruptures - aniridia (absence of iris) - hemihypertrophy (increased size of half the body) - urinary defects treatment - radiation, chemo, surgery considerations - do not palpate the abdomen!! to prevent rupture of encapsulated tumor, spreads cancer cells

retinoblastoma

patho - malignant tumor of retina, noticed in infancy or early childhood - can be slow or fast growing s/s - leukocoria (cats eye reflex) whitish glow in the pupil noticed in flash photos - strabismus - red painful eyes - blindness treatment - removal of eye, fitted for prosthesis

rhabdomyosarcoma

patho - most common pediatric soft tissue sarcoma - starts in skeletal or smooth muscle cells - causes tumors all over but commonly in head/neck, GI, extremities, and trunk - important to assess all lesions - 5 year survival rate of 65% - most common in children<10 cause - unknown, genetic and environmental links diagnosis - biopsy treatment - surgery (complete removal) and chemo

treatment/considerations of leukemia

treatment - chemotherapy is most common, often followed by radiation - stem cell or bone marrow transplants (autologous or allogenic) considerations - assessment: vague complaints such as fatigue, limb pain, night sweats lack of appetite, HA, bleeding issues, and malaise - total treatment time around 2 years

bone tumor: ewing sarcoma

- 2nd most malignant bone tumor in children - can occur in any bone but most common in pelvis, thigh, upper arm, or ribs - cancer of primitive nerves found within bone, cartilage, or soft tissue) - can occur at any age, but most common in children/adolescents during rapid growth s/s - pain in the affected area that gets progressively worse - swelling and tenderness risk factors - more common in europeans, less common in africans or east asians

side effects of chemo and radiation

- NV (give antiemetics before and after) - anorexia, constipation, diarrhea, mouth ulcers (mouth care) - hair loss, may have different color and texture when grows back - neutropenia

causes of childhood cancer

- chemical carcinogens and drugs - radiation exposure - viruses - most of time unknown - increased risk with downs syndrome

common treatments of cancer in pediatric pts

- chemotherapy - surgery - radiation - stem cell transplantation - newer immunotherapy

medical emergencies to monitor for after chemo or radiation

- hemorrhagic cystitis - tumor lysis syndrome - septic shock

most common types of cancer

- leukemia (33%) - brain tumors (25%) - lymphomas (8%)

lymphomas

- malignant tumors or lymphocytes - represent about 1/4 of childhood cancers 2 types - non-hodgkins lymphoma - hodgkins lymphoma

bone tumor: osteosarcoma

- most common primary bone tumor in children - tumor of osteoblasts - usually found in long bones (common at metaphyses around knee) - mostly commonly seen in teens (15) s/s - bone pain, warm mass or lump that can be felt through skin, limping, limited movement, broken bone, fever

cancers unique to children

- neuroblastoma - wilms tumor - rhabdomyosarcoma - retinoblastoma

lymph nodes

- normally small, mobile, non-tender, not warm to touch - infectious process if quickly enlarging, warm, firm, reddened, tender - possibly cancerous if slowly enlarging, firm, non-tender

leukemia patho/cause/diagnosis

- proliferation of immature WBCs, these cells then compete with other body cells for space and nutrients leading to low RBCs and platelets - apoptosis: increased rate of cell growth and decreased cell death - most common type of cancer: acute lymphocytic leukemia cause - unknown - genetic links (identical twins and down syndrome) - exposure to radiation - treatment with anticancer agents diagnosis - microscopic exam of blood shows proliferation of immature leukocytes - bone marrow aspiration or biopsy (confirmation test) - lumbar puncture for presence of CNS disease and staging
