Oncology Flashcards
Immunodeficiencies that predisposed to cancer?
Wiskott-Aldrich syndrome – lymphoma and leukemia
X linked lymphoproliferative disease – lymphoma
Most common causes of cancer in pediatrics?
Leukemia >brain tumors >lymphoma >neuroblastoma >tissue sarcoma > Wilms tumor >bone tumor
Cancer related to:
- Down syndrome
- Turner’s
- Trisomy 13
- Trisomy 18
- Kleinfelter (3)
- Leukemia (ALL/AML)
- Chondroblastoma
- Leukemia, teratoma
- Wilms tumor, neurogenic tumor
- Leukemia, germs cell tumors, breast cancer
Cancer related to:
- Fanconi anemia
- Xeroderma pigmentosa
- Ataxia telangiectasias
- Bloom syndrome
- Leukemia
- Basal/squamous cell carcinoma, melanoma
- Hodgkins, non-Hodgkin’s, leukemia, sarcomas
- Leukemia, lymphoma, solid tumors, GR malignancy
Cancer associated with:
- Beckwith-Weidemann syndrome
- Neurofibromatosis I
- Neurofibromatosis II
- Wilms tumor, hepatoblastoma, rhabdomyosarcoma, and adrenocortical carcinoma
- Brain tumors, lymphoma, leukemia, schwannoma
- Acoustic aroma
Abdominal mass – two cancers?
Truncal/extremity masses – two cancers?
Wilms tumor, neuroblastoma
Rhabdomyosarcoma, bone tumor
Most common childhood cancer? The most common phenotype? Marker? Clinical features? Diagnosis?
ALL; pre-B-cell phenotype; common acute lymphocytic leukemia and teaching (CALLA)
- Fever bone/joint pain
- Pallor, bruising, hepatosplenomegaly, lymphadenopathy
- Testicular pain, epistaxis may also be present
Marrow replacement with blasts; no staging system
Favorable prognostic outcome with ALL if?
White female 1-9 years with WBC <50,000, no organ involvement, CALLA positive
Stages of ALL treatment?
- Induction – destroy cancer cells (methotrexate, vincristine, L-asparaginase, corticosteroids)
- Consolidation – prevent CNS involvement (methotrexate, cranial irradiation if over 5)
- Maintenance – three years of chemotherapy
- Bone marrow transplant for high-risk children/relapse
Tumor lysis syndrome – Electrolyte abnormalities (and complications)?
- Hyperuricemia (Renal insufficiency)
- hyperkalemia (Cardiac dysrhythmias)
- hyperphosphatemia (Hypocalcemia with tetany)
Treatment side effect that causes:
- Pancreatitis?
- Cardiomyopathy?
- Cystitis?
- Hormonal problems?
- L-asparaginase
- Doxorubicin
- Cyclophosphamide
- Irradiation
Childhood AML – associated with (4)? clinical features? Diagnosis? Management?
Down syndrome, Fanconi anemia, Kostmann syndrome, neurofibromatosis
Similar to ALL but with more CNS involvement (fever hepatosplenomegaly, gingival hypertrophy, bleeding, bone pain)
Blood smear and bone marrow biopsy
Intensive myeloablative therapy and bone marrow transplant
Juvenile CML – chromosomes affected? Chromosome abnormality not present? Clinical features? Treatment? Prognosis?
7, 8; Philadelphia chromosome not effected
Fever, chronic eczematous rash, lymphadenopathy, petechia, anemia, moderate leukocytosis
BM transplant; Usually Fatal
Hodgkin’s lymphoma – associated with? Clinical features? Diagnosis? Management? Prognosis?
EBV
Painless cervical/supraclavicular lymphadenopathy
Redd-Sternberg cell
Chemotherapy/radiation therapy
Excellent
Hodgkin’s disease versus non-Hodgkin’s lymphoma:
- Symptoms onset
- Common location
- Systemic symptoms
- Abdominal findings
- Painless lymphadenopathy
- SVC syndrome
- Airway compression
- Slow versus rapid
- “Cervical/supraclavicular versus the abdominal, mediastinal, supraclavicular
- Common versus rare
- Rare versus common
- Common in both
- Rare versus common
- Rare versus common
