Leukemia And Lymphoma Flashcards
N. What’s the most common malignant disease in children?
Acute lymphocytic leukemia

Chronic myeloid leukemia
N. Name the cell type that is predominantly present in acute leukemia?
Early hemopoietic progenitor cells
N. What are the steps in diagnosis acute lymphocytic leukemia?
Blood film, imunnophemotyping, genetic analysis
N. In acute lymphocytic leukemia, if the chromosomes abnormalities was ( less than 46 chromosomes = hypodiploidy, or there’s BCR-ABL ( Philadelphia t 9:22) . We know the prognosis is…..
Poor
N. Treatment of acute lymphocytic leukemia consists of 3 steps. Name them?
Remission induction: initial chemotherapy that kills most of the tumors cells /
Consolidation : blocks of intensive chemotherapy to kill the rest of cancer cells /
Maintenance : less intensive treatment is given for 1-2 years taken as tablet or injection
N. What are the most important drugs used for treatment of acute lymphocytic leukemia? 4
Steroids (to kill lymphoblasts) / vincristine (affect microtubules) / daunorobicine ( chemotherapy) / Asparaginase (⬇️ aminoacids
N. Other drugs used in acute lymphocytic leukemia are….? 3
Cytosine arabinoside ( analogue) / CNS chemotherapy: by high dose IV or directly by intrathecal chemotherapy / bone marrow transplantation
N. acute myeloid leukemia affects all ages, it may develop from pre malignant condition & genetic analysis is very important. True or false.
True
N. What’s the most common concern/complication of acute promyelocytic leukemia?
Disseminated intravascular coagulation ( DIC )
N. Acute promyelocytic leukemia is caused by t …. : ….. translocation
t 15:17 translocation
N. What’s the name of the drug used in acute promyelocytic leukemia in conjunction with chemotherapy?
All- trans retinoic acid ( ATRA )
N. Cure rates for A.L.L in children is 85% while AML is only 50% in children and <8% in adults >65 years. True or false.
True
N. …….is common site for relapse in acute lymphocytic leukemia.
CNS
N. Chronic lymphoid leukemia develops from accumulation of a clone of …..cells in the bone marrow, blood, lymph nodes which is used for diagnosis
B cells ( which have phenotype CD5+ CD23+ )
N. Most of chronic lymphoid leukemia cases are discovered in routine check up and therefore the treatment in mild cases is watch and wait. True or false?
True
N. What’s the standard treatment in chronic lymphoid leukemia after the watch and wait phase?
Antibody against B cells ( CD20 ) with chemotherapy ( usually 6 courses are given )
N. What’s the MOA for the new tablet used to treat chronic lymphoid leukemia?
Blocks B cell receptors signaling through inhibition of BTK or PI3K delta
N. In treating chronic myeloid leukemia the ptn is giving a tablet that acts only on CML tumor cells by inhibiting the bcr-abl kinase protein. What is the tablet called ?
Imatinib
N. In ptn with CML resistant to imatinib tablet, what’s the new other alternative drug?
Tyrosin kinase inhibitors
N. Ebstian bar virus ( EBV is ) ass with ………… lymphoma
Hodgkin lymphoma
N. What’s the characteristic feature that is found in biopsy for Hodgkin lymphoma ptn?
Reed-Sternberg ( RS ) cells ( they have bilobed nuclei and derived from B cell and express CD15, CD30 )
N. What’s the standard chemotherapy regimen used in Hodgkin lymphoma?
ABVD ( adriamycin, bleomycin, vinblastine, dacarbazine )
N. In diagnosis of lymphoma we use biopsy with PET scan that involves injection of ……..glucose
Flurodeoxyglucose (FDA )
