Hodgkin Lymphoma Flashcards by Michael Pierro

What is the classic pathology finding in Hodgkin Lymphoma?

Reed-Sternberg cells surrounded by inflammation
RS cells recruit inflammatory cells, and then only make up 10% or less of the whole tumor

FDG uptake is less than mediastinum. Deauville?

FDG is moderately increased compared to the liver, but is improved from baseline, no new sites of disease. Deauville?

What drugs are in ABVD?

Doxorubicin
Bleomycin
Vinblastine
Dacarbazine

Treatment options for early stage, favorable HL

PET Adapted ABVD after 2C
If PET negative, then ISRT 20 Gy or ABVD x1C + ISRT 30 Gy
If PET DS3, then AVD 4C or ABVDx2+ 30Gy ISRT
If PET DS4, then 2C ABVD and anothher PET.

Treatment for nonbulky unfavorable early stage HL?

PET-Adapted ABVD (if non-bulky)

Patient with newly diagnosed advanced stage HL is treated with ABVD. PET after C2 shows Deauville 2. What to do?

Omit bleomycin and do AVD for 4 more cycles

What treatment regimen provides the best disease control in advanced stage HL?

Escalated BEACOPP
(Bleo, Etop, Doxo, Cyclophos, Vincristine, Procarbazine, Pred)

Significant toxicities with BEACOPP (2)

Infertility
MDS/AML

For those with advanced stage HL, which patients would benefit most from Brentuximab vedotin + AVD? (3)

Younger patients (<60) Multiple extranodal sites Stage IV

Treatment options for advanced stage HL? (2)

N-AVD (Nivolumab, Doxo, Vinblast, Dacarbazine) BrECADD (Bv, Etop, Cyclophos, Doxo, Dacarbazine, Dex) PET-Adapted ABVD Bv-AVD (not as good as N-AVD but that's a new regimen)

N-AVD was compared to Bv-AVD. What what the PFS comparison?

N-AVD was better across subgroups

What was the treatment outcome difference between BrECADD and escBEACOPP

BrECADD improved PFS and was less toxic

What is the general treatment paradigm for R/R HL?

Salvage chemotherapy followed by autoHCT

What are examples of salvage chemotherapy regimens used in R/R HL? (4)

ICE, DHAP, GVP, GDP

What is prognostic after salvage chemotherapy for good outcomes?

PET negative CR prior to autoHCT

Treatment options for R/R HL after autoHCT? (3)

Brentuximab vedotin Nivo Pembro (should be done before BV)

Who is eligible for BV consolidation therapy after AutoHCT? (4)

Relapse within 1 year of frontline therapy Extranodal disease at relapse PET+ at time of transplant >1 salvage therapy

How to sequence BV and Pembro in R/R HL?

Pembro first

Treatment of Stage I Nodular LP HL?

RT alone

Early stage treatment of Nodular LP HL?

R-CVP

Treatment of advanced Nodular LP HL?

R-CHOP R-CVP

In patients with HL who received RT, how do you manage secondary cancer risk?

Mammograms yearly after mediastinal/axillary RT (or MRI in pts <30) Start 8-10 years after treatment or at 40 years old

Treatment for bulky favorable early stage HL? (3)

ABVD x4 + 30 Gy IF RT BEACOPP x2 + ABVD x2 + 30 Gy ISRT ABVD x6

Describe the PET-Adapted approach to ABVD in unfavorable early HL?

2 cycles of ABVD - then PET. If PET is DS 1-3, then AVD x4C is given, or ABVDx2 + ISRT 30 Gy. If PET is DS 4-5, then escBEACOPPx2. Then another PET. If that's DS1-3, then BEACOPPx2 or ISRT 30 Gy

What type of HL is treated distinctly from classic HL and other variants? How is it treated differently?

Nodular lymphocyte predominant HL It's CD19 and CD20+, so Rituximab based regimens are useful

Describe the PET-adapted approach to favorable, early stage HL?

After 2C ABVD: DS 1-2: ISRT 20 Gy OR ABVD x1 + ISRT 30 Gy OR ABVD x2C DS 3+: BEACOPP +/- ISRT
