Haematology 5 - lymphoma 2 Flashcards
Radiotherapy dilemma in HL
Rdiotherapy can increase cure rate but more patients die of secondary malignancies
CD5+ and CD19+ cells
B-CLL, these cells should have switched off CD5
hODGKIN’S LYMPHOMA epidemiology
M>F (but more common in F in 20-30s)
Bi-modal: 20-29 most common then >60
Which subtype of HL is more common in females?
nodular sclerosing type
Where does HL arise f rom?
GC or post GC
Which virus is HL associated with?
EBV
Diagnostic markers for HL
CD30, CD15, CD20-ve
Most common type of HL
Nodular sclerosing
Classical HL with poor prognosis
Lymphocyte depleted
disorder of the elderly multiple recurrences (HL)
Nodular Lymphcoyte Predominant HL
Difference between NLPHL and Classical HL
Not associated with EBV
No eosinophils or macrophages
Can transform in to high grade B cell lymphoma (NHL)
Negative for CD30 + CD15, positive for CD20
Staging methods for HL
FDG-PET, CT, biopsy
In Ann Arbor staging, what is the spleen considered as?
One giant lymph node
Main complications of nodular sclerosing HL
SVCO, tracheal compression
1st line mx of HL (chemo)
1st: ABVD Adriamycin Bleomycin Vincristine Dacarbazine
Given at 4-weekly intervals, preserves fertility
2nd: PET-CT –> Radiotherapy
Long term consequences of ABVD
Pulmonary fibrosis
Cardiomyopathy
Disadvantages of radiotherpay in HL
Collateral damage + increased risk of breast/lung/skin cancer, leukaemia, myelodysplasia
Mx of patients who relapse?
High dose chemotherapy + autologous SCT
3rd line: anti-CD30 +ANTI-PD1
