AML, Lung Ca Flashcards
(43 cards)
What is the most common leukemia in adults?
AML
What is the most common leukemia in children?
ALL
What lab finding is characteristic of acute leukemia?
Pancytopenia with circulating blasts
What cytogenetic abnormality is associated with acute promyelocytic leukemia (APL)?
t(15;17)
Which acute leukemia is associated with Auer rods?
AML
What is the treatment for APL (M3 subtype of AML)?
ATRA (all-trans retinoic acid) + arsenic trioxide
What serious complication can occur after ATRA initiation in APL?
Differentiation syndrome (fever, pulmonary infiltrates, hypotension)
Which leukemia has a high risk of DIC?
APL (a subtype of AML)
What cell marker is positive in AML?
Myeloperoxidase (MPO+)
What cell markers are typical in ALL?
TdT+ (marker of immature lymphoid cells), CD10+ (CALLA), CD19+ (B-cell)
What cytogenetic change in ALL has a poor prognosis in adults?
Philadelphia chromosome t(9;22)
What CNS prophylaxis is required in ALL?
Intrathecal methotrexate (± cytarabine)
What signs and symptoms may suggest ALL?
Bone pain, hepatosplenomegaly, lymphadenopathy, CNS involvement
What age group is ALL most common in?
Children (ages 2–10)
What is tumor lysis syndrome, and when does it occur?
Rapid cell lysis after chemo; ↑K⁺, ↑phosphate, ↓Ca²⁺, ↑uric acid → renal failure
How is tumor lysis syndrome prevented?
IV fluids, allopurinol or rasburicase
What is the most common cause of death during induction therapy for AML?
Infection or bleeding (due to pancytopenia)
What is the best initial test for suspected acute leukemia?
CBC with peripheral smear
What is required for definitive diagnosis of AML or ALL?
Bone marrow biopsy with >20% blasts
What treatment is used in AML (non-APL)?
Cytarabine + anthracycline (e.g., daunorubicin or idarubicin)
When is stem cell transplant considered in acute leukemias?
Poor prognostic markers or relapsed/refractory disease
What are the two major categories of lung cancer?
Small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC)
What are the main subtypes of NSCLC?
Adenocarcinoma, squamous cell carcinoma, large cell carcinoma
Which lung cancer is most common in non-smokers and women?
Adenocarcinoma
