Malignancies 2 Flashcards
malignancies from the lymphoid line
b cell neoplasms: lymphoma, myeloma
t cell neoplasms
amyloidosis
most common type of lymphoid neoplasm
non hodgkin lymphoma –> diffuse large b cell lymphoma, indolent follicular lymphoma
most common cancer in children
acute lymphoblastic leukemia
clinical picture of lymphoid malignancies
lymphadenopathy
splenomegaly
constitutional symptoms: weight loss, night sweats, irritable
anemia, thrombocytopenia
infectious agents associated with lymphoid malignancies
ebv, htlv-1, hiv, hepatitis c virus, h. pylori, hhv 8
associated syndromes with all
trisomy 21
bloom syndrome
fanconi anemia
common causes of all
idiopathic!!
ionizing radiation
chemicals, drugs
clinical manifestations of all
lymphadenopathy and organomegaly
cns involvement
testicular seeding
special chemo technique used in all
intrathecal chemo
reason why males have to be treated longer for all
testicular seeding: chemo cannot penetrate testis
diagnosis for all
morphology cytochemical analysis (-) myeloperoxidase immunophenotyping flow cytometry, cytogenetics, fish markers
induction phase for all treatment
use heavy chemo to induce remission
consolidation and maintenance phase of all treatment
to prolong remission or achieve cure
if refractory: bone marrow transplant, tki
length of all treatment
2-3 years, longer for males
clinical presenting features of all
fever!! bleeding bone pain lymphadenopathy splenomegaly hepatosplenogmegaly!!
lab findings for all
leukocyte <10,000
hgb <7
platelet <20,000
lymphoblast L1 > L2 > L3
patho of chronic lymphocytic leukemia
proliferation of mature lymphocytes
characteristics of cll
no lymphoblasts
patients are in immunodeficient state
indolent course = can just observe
peripheral smear in cll
mature lymphocytes (chromatin does not show) scattered among lymphocytes are basket cells/smudge cells
staging of cll
