Q

How does nLPHL differ (from HL) with respect to:
Clinical course
Age of onset
Relationship to NHL

A

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.

A

LP cells are typically CD20+, BLC6+, CD15-, and CD30-, CD 45+.

L&H ‘popcorn’ cells instead of Reed-Sternberg cells

Q

What is the molecular target of Brentuximab Vedotin?

What is the mechanism of Vedotin?

A

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.

Q

Causes of death in 2 groups of echelon I study

A

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.

Q

What were the criteria for enrollment in the AETHERA trial in HL?

A

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
