Leukemia/Lymphoma/Multiple Myeloma Flashcards
Leukocytosis
WBC greater than 10,000
Acute Myeloid Leukemia Epidemiology
Most common ACUTE leukemia in adults. White, males 65yo.
Acute Myeloid Leukemia Definition
accumulation of luekemic blasts in blood and bone marrow. With reduced production of normal cells (neutrophils, erythrocytes, platelets)
Acute Myeloid Leukemia Associations
Chemical exposure, some genetics, Myelodysplastic syndrome.
Acute Myeloid Leukemia Presentation
Anemia: angina, dyspnea with exertion, fatigue, pallor.
Neutropenia: delayed healing, enterocolitis, fever, infection, oral lesions, perianal abscesses, pneumonia, sinusitis.
Thrombocytopenia: bleeding, conjunctival hemorrhages, eccymoses, epistaxis, gingival bleeding, petechiae.
Acute Myeloid Leukemia prognosis
Good in younger patients. Poor if developed from myelodysplastic syndrome.
Acute Myeloid Leukemia CBC
elevated/decreased WBC, cytopenias, blasts
Acute Myeloid Leukemia peripheral smear
Auer Rods: elongated needles in neutrophils, clumps of azurophilic granule material.
Acute Myeloid Leukemia metabolic panel
elevated creatine and liver function tests. altered electrolytes. Elevated uric acid and LDH.
Acute Myeloid Leukemia bone marrow biopsy
Blasts greater than 20%.
Acute Myeloid Leukemia treatment
Induction: chemo
consolidation: stem cell transplant
Myelodysplastic syndrome Definition
ineffective hematopoiesis with cytopenia. Can progress to AML.
Myelodysplastic syndrome epidemiology
males, 60 years old. chemical exposure can be treatment related (chemo 4-6 years later).
Myelodysplastic syndrome treatment
hematopoietic growth factors, immunomodulatory agents, hypomethylating agents, immunosuppressants
Tumor Lysis syndrome Definition
Oncological emergency. Massive tumor cell lysis causes release of cellular contents (K, Pi, nucleic acids etc.)
Tumor Lysis syndrome causes
Initiation of cytotoxic treatment and can occur spontaneously.
Tumor Lysis syndrome treatment
Prevention! fluids, diuresis, monitoring. Xanthine oxidase inhibitors, monitor cardiac function, seizure precautions, dialysis, treat the hyperkalemia and phosphatemia.
Chronic Myelogenous Leukemia Epidemiology
Males around 50yo. Risk factors are ionizing radiation and benzene.
Chronic Myelogenous Leukemia definition
Clonal malignancy of B-lymphocytes. Due to transposition of 9 and 22 on the philadelphia chromosome.
Chronic Myelogenous Leukemia presentation
fatigue, malaise, abdominal fullness, splenomegaly, B symptoms (fever, weight loss and night sweats).
Chronic Myelogenous Leukemia Chronic Phase
Lasts 5-6 years 80% are diagnosed here. WBC is greater than 10,000. High chance of remission if caught here.
Chronic Myelogenous Leukemia Accelerated Phase
Anemia, fatigue, malaise, flu-like symproms. 10-19% of blasts.
Chronic Myelogenous Leukemia Blast Crisis Phase
20% or more are blasts. Fever extramedullary blasts and splenomegaly.
Chronic Myelogenous Leukemia diagnosis
bone marrow biopsy shows philadelphia chromosome.
Chronic Myelogenous Leukemia treatment
Tyrosine Kinase inhibitors like Gleevac(imantinib) or an allogenic stem cell transplant=curative.
Chronic Myelogenous Leukemia Complications
Tumor lysis syndrome, hyperluekocytosis, Hyperviscosity.
