HL Flashcards
Factors in the IPS for Hodgkins
“SAW MEAL”
Stage IV
Age >/= 45
WBC >/=15
Male
Erythrocytes <105
Albumin <40
Lymphocytes <0.6 or 8% of WBCs
Low Risk (0‐1) Intermediate Risk (2‐3) High Risk (4‐7)
How does nLPHL differ (from HL) with respect to:
Clinical course
Age of onset
Relationship to NHL
Clinical course: More indolent, less BSx, early stage disease,
LAD but not contiguous (popcorn) usually only symptom (liver, spleen, medistinal involvement rare)
DO have high relapse.
Age: Age of onset 40s. cHL bimodal peak at 20-30 and 60s.
-mostly male
Relationship to NHL Risk of transformation to aggressive NHL–>30% at 20 years
nLPHL immunophenotype and histologic findings.
LP cells are typically CD20+, BLC6+, CD15-, and CD30-, CD 45+.
L&H ‘popcorn’ cells instead of Reed-Sternberg cells
Treatment of nLPHL
- Limited stage-RT
2. Advanced stage- No consensus- single agent Ritux( if frail), R-CHOP, ABVD, R-CVP, BEACOPP
What is the molecular target of Brentuximab Vedotin?
What is the mechanism of Vedotin?
Microtubule disrupting agent (MMAE is the actual drug)
Antibody drug conjugate →binds to CD30, internalized and releases MMAE which binds to the tubules and disrupts the cellular microtubule network, inducing cell cycle arrest (G2/M phase) and apoptosis.
What are two indications for immediate therapy for hypereosinophilia of unclear etiology outside of end-organ dysfunction?
o Very high PB eos (>100)
o Signs/symptoms or leukostasis
What are four treatments for hypereosinophilic syndrome?
- Glucocorticoids
- Imantinib (PDGFRA/B)
- Hydroxyurea
- INF-alpha
- Anti IL-5 (Mepoluzimab)
- Alemtuzumab (anti-CD52)
- HSCT
- Ruxolitinib (if JAK-2 positive)
- FGFR1- pemigatinib, sorefenib, ponatinib
Name a drug associated with lymphadenopathy
Phenytoin
Causes of death in 2 groups of echelon I study
ECHELON-1 trial (NEJM 2018)
o ABVD vs A+AVD for frontline cHL
o Incl: Stage III/IV cHL, previously untreated
Primary endpoint: modified PFS (death, progression, new cancer tx, non-complete response)
82.1% vs 77.2% at 24.6 months (p=0.04)
–>more neutropenia and peripheral neuropathy in Brentuximab group. More pulmonary toxicity in ABVD.
What were the criteria for enrollment in the AETHERA trial in HL?
AETHERA trial (Lancet 2015)
o Do patients with unfavourable RFs pre-autoSCT benefit from maintenance BV post auto-SCT
o Incl: Primary refractory, initial remission duration of < 12 mo, or extranodal involvement at start of salvage.
o median PFS 42.9 mo for BV versus 24.1 mo for placebo.
o Most frequent AE was peripheral neuropathy, neutropenia
