Hodgkin Lymphoma Contouring

Question 1

RT as single modality in Hodgkin Lymphoma (LPHL)

Answer 1

RT is relevant for early stage lymphocyte-predominant HL. The CTV should be more generous because microscopic disease is more likely to be present without chemotherapy.

Question 2

ISRT if RT as single modality (LPHL)

Answer 2

Question 3

RT with combined modality treatment in HL

Answer 3

Early stage classical Hodgkin Lymphoma (but it also applies to early-stage DLBCL). In these cases, RT is part of overall treatmen and ist not simply consolidation (even if it a CR in PET). RT is given to allow less Chemo/ RT is compensating for less Chemo.
