Lymphoma Flashcards
CD20/21+, CD5- CD10+, BCL-6+, BCL2+, t(14;18)
follicular lymphoma
cyclin D1 translocation and disease
t(11q14), mantle cell lymphoma (MCL)
when to treat follicular lymphoma
GELF positive: B symptoms Splenomegaly Pleural effusion or ascites 3 node sites >3 cm one node >7 cm cytopenias leukocytes or plts <100 leukemia
Single agent rituxan in follicular lymphoma
Data shows single agent robust activity
74% RR 4 weeks of weekly ritux
RESORT trial maintenance was not helpful for OS, prefer retreat when recurrs
PRIMA trial
relapse risk determined by FLIPI
given R+ chemo of some kind then maintenance ritux for 2 years 375 mg/m2 every 8 weeks or not
PFS 75 vs 58 but no OS
stage I or stage II low grade treatment
confirm stage with PET and BMB
Local radiation preferred with high long term cure DFS and about 40% cure rates
B cell lymphoma with >15 centroblasts/hpf and solid sheets of centroblasts and treatment
grade 3B follicular lymphoma is treated with R-CHOP, >65 and poor PS BR
Gastric MALT t(11;18) translocation/FISH
predicts a lack of benefit to H. pylori therapy <5%, treat for H pylori and do radiation or rituximab if contraindicated
Marginal Zone lymphoma
Marginal zone is marginal
Splenic marginal zone is associated with Hep C and treatment of hep c can induce remission.
Immunophenotype tend to be “bland” CD20/22+ but
CD5-, CD10-, CD25-, CyclinD-, CD 103-
CD23+/-
Mantle cell lymphoma maintenance therapy
Yes after aggressive therapies
Elderly or not transplant eligible after R-CHOP but not BR
3 years showed improved OS
first line therapy for mantle cell lymphoma
agressive vs non-aggressive
R-CHOP/R-HyperCVAD
aggressive features for mantle cell lymphoma
ki67>30%
blastoid variant
features for increased risk of CNS involvement in DLBCL
4-6 risk factors CNS IPI age >60 LDH elevated PS>1 Stage III or IV Extranodal involvement >1 site
Independent factors that support auto use Testicular high grade double hit leg primary IE of the breast kidney or adrenal gland
cHL immunophenotype
CD 30+, CD15+/-, CD2-+/-, PAX5+ MUM1+
CD 30+, CD15+/-, CD2-+/-, PAX5+ MUM1+
