MZL facts Flashcards
gastric MALT % with HP
66%
BM involvement in MALT
< 10%
no need for BMB
MZL-IPI
MZL subtype (nodal or disseminated)
LDH
Cytopenias (Hb <12, Lymphocyte < 1000, Platelets <100 × 109/L)
POD24 in MALT
inferior OS
increased risk of transformation
MLT-IPI
age>70
LDH> ULN
Stage III/IV
HP eradication in gastric MALT
70% CR
Tests after eradication of HP
confirm eradication 6 weeks after Tx, and 2 weeks after PPI discontinuation
repeat endoscopy 3 mon after eradication
Timing of endoscopic FU after eradication
not sooner than 3 months after eradication
then- every 3 mon for 12 months. define disease progression only after 12 months,
pts predicted to not respond to eradication in gastric MALT
t(11:18)
HP negative
Tx with RT
Tx of ocular MALT
Doxycycline 6 months- pulsatile
50-75% ORR
RT dosage for ocular MALT
4 Gy
in order to reduce catarct
ocular MALT pathogen
C. psittaci
Bronchial MALT Tx
Surgical resection
RT for remaining lympoma
RX4 for no resectable tumors
Dural EMZL
More common than DLBCL of dura
usually diagnosed after resection
Tx choice is RT if not already resected
Colonic EMZL
rare
usually polypectomy is enough
