Oncology Flashcards
Work in progress-cards soley from Nelson's
Most common childhood cancers
leukemia or lymphoma
Peak incidence of embryonal tumors (neuroblastomas and retinoblastomas)
first 2 years of life
Peak incidence of ALL
2-5 yrs
Common symptoms for T-cell ALL and Non-Hodgkin Lymphoma
lymphadenopathy and organomegaly
General differences between malignant and infectious/inflammatory masses
malignant masses are firm, fixed, nontender. infectious/inflammory masses are softer, mobile, tender
Common metabolic emergency often seen in treatment of leukemia and lymphoma where large amounts of phosphate, potassium, and uric acid are released from lysed cells
tumor lysis syndrome
Define adjuvant therapy
chemotherapy administration after removal of the primary tumor
Protein kinase inhibitor that targets the effects of the t(9;22) translocation of chronic myeloid leukemia and acute lymphoblastic leukemia
Imatinib mesylate
Common extramedullary site for ALL
testes
Clinical presentation includes: older males (8-10), high WBC count, mediastinal masses, cervical lymphadenopathy, hepatosplenomegaly, CNS involvement
T-cell ALL
Characterized by immature blast cells, anemia, thrombocytopenia, and low/nml/high WBC count
acute leukemia
Why is treatment of AML different than ALL?
nonmyelosuppressive drugs are not effective for AML
Classification of low risk in ALL
1-9 yrs old, initial WBC count < 50,000, and favorable cytogenics t(12;21) translocation
Overall cure rate for childhood ALL and AML
ALL-80%. AML-50%
What do the following have in common: small noncleaved cell (Burkitt), lymphoblastic, and large cell?
histologic subtypes of NHL
