Hodgkin lymphoma

The one linked with EBV
Etiology Cancer of mature B cells
Reed-Sternberg cells quoted as having EBV antigens in 20-40% cases
Epidemiology biphasic incidence – young adults and elderly.
Risk factors: affected sibling, EBV, SLE, post-transplantation, obesity
Clinical presentation Painless cervical/supraclavicular lymphadenopathy
B symptoms; "rubbery" cervical LNA; lymph nodes may be painful on alcohol consumption in 10%. Mediastinal mass can cause SVCO
Pathogenesis
Diagnostic investigations LN excision biopsy
FBC: ↓ Hb, Plt
Lymph node biopsy: Hodgkin-Reed Sternberg cell (“mirror image nuclei”) = ~CD30+
Management 80-90% curable! Radiotherapy has some role but often widespread
➥ Stage I-II = 2x ABVD + 20Gy radiotherapy; I-II with risk factors = 4x ABVD
➥ Advanced: 6x ABVD 80-85% cure
➥ Monitor for late toxicity- lung, cardiac, fertility, Ca breast
➥ New: risk-adapted therapy, anti-CD30, checkpoint inhibitors
