Q

How is Hodgkin’s Lymphoma staged and why is this important?

A

Following pathological dx of a LN biopsy patients are ‘staged’ this has prognostic significance + also may determine the best approach for therapy.

FDG-PET/CT scan

Consider biopsy of other site if possibly infiltrated e.g. liver

Q

What is the management for classical Hodgkin’s Lymphoma?

A

Combination chemotherapy - ABVD:

  • Adriamycin
  • Bleomycin
  • Vinblastine

A

Chemotherapy (essential for cure)

Pneumococcal Covid19 Seasonal flu **Avoid live vaccines**
42
Watch and wait is the preferred approach to CLL. When should treatment be given?
**Progressive lymphocytosis:** * \>50% Increase over 2m * Lymphocyte doubling time \<6m **Progressive BM failure:** * Hb \< 100, platelets \<100, neutrophils \<1 **Massive or progressive lymphadenopathy/splenomegaly** **Systemic Sx** **AI cytopenias (treat with immunosuppression not chemotherapy)**
43
What therapy can be offered for CLL patients?
Combination Immuno-chemotherapy (being superseded by targeted Rx) **Targeted Therapy:** * BTK inhibitor * BCL2 inhibitor **Cellular therapy only for relapsed high risk cases:** * Allogeneic SCT * CAR-T therapy
44
Which BCR kinase can be used to treat CLL?
**Ibrutinib (BTK)** Idelalisib (PI3K)
45
Which BCL2 inhibitors can be used to treat CLL?
Venetoclax
46
Which experimental cell based therapies can be used to treat CLL?
Chimeric Antigen Receptor T cells (CAR-T)
47
How does venetoclax work in CLL?
Orally active Bcl 2 inhibitor, permits apoptosis of CLL cells. In high risk CLL p53 mutated 85% response + maintained at >1y. Main risk is tumour lysis syndrome when initiating therapy (potentially fatal).
