- rapid progression
Is auto HSCT an option in 1st remission for follicular lymphoma?
no
In FL, what treatment would you use if pt was given 1L rituxan and had remission for >6mo?
retreatment with rituxan
how do you treat grade 3b FL (defined as >15 centroblasts with solid sheets of centroblasts)
as DLBCL; RCHOP
Maintenance therapy for FL for pts who present with high tumor burden?
Rituximab q2-3mo for 2 years
Tx for R/R FL that targets EZH2?
tazemetostat (methyltransferase inh)
MALT lymphoma that is H. pylori positive that carry this mutation are resistant to H. pylori -directed ABx.
t(11;18). need to add ISRT
Splenic MZL is associated with which virus?
Hep C
SMZL immunophenotype?
CD20+, CD22+, negative for CD5, CD10 and cyclin D1. lacks CD25 and CD103 which are positive in hairy cell leuk
Tx SMZL?
splenectomy or Rituxan. treat Hep C if positive as this may cause lymphoma to regress
low intensity regimens for mantle cell lymphoma?
BR
R-CHOP
VR-CAP
R2
BR + Cytarabine
ibrutunib dose in mantle cell lymphoma?
560mg PO daily
Aggressive treatment regimen for mantle cell should include?
cytarabine
high risk scenarios for CNS relapse in DLBCL?
- high CNS IPI score
- testicular lymphoma
- double or triple hit
primary cutaneous DLBCL, leg type - stage IE DLBCL of breast
- kidney or adrenal involvement
Treatment approach for nasal NK/T-cell lymphomas?
chemo RT. all regimens contain asparaginase
virus associated with PEL?

Rosai Dorfman Disease
Tx for Rosai Dorfman Disease? localized disease?
First observe as 80% spontaneously improve; surgery; multifocal disease treated with COBIMETINIB, cladribine, cytarabine, MTX, or prednisone
treatment approach for T-PLL? (T-prolymphocytic leuk)
alemtuzumab-based therapy
breast-implant associated lymphoma?
anaplastic large-cell lymphoma (7-9 years after implant)
Do plasmablastic lymphomas express CD20? Virus association?
No; HIV – treat with EPOCH and IT chemo
preferred tx for ALCL ALK+? Second line?
BV-CHP; alectinib or crizotinib
Ppx needed for polatuzumab?

Castleman’s disease aka giant lymph node hyperplasia is defined as active when:
- fever
- increase serum CRP >20
- 3 of the following symptoms: LAD, large spleen, edema, effusion, ascites, cough, nasal obstruction, xerostomia, rash, central neurologic symptoms, jaundice, AIHA
Treatment for pulmonary lymphomatoid granulomatosis (PLG)?
Asymptomatic: withdraw implicated medication (azathioprine, methotraxate, etc) and observe
