19
Q

What is given in combination with high-dose chemo for highly aggressive HNL?

A

CNS/ cranial irradiation

20
Q

What agents are used to treat highly aggressive NHL?

A

R-CHOP is not adequate; need more

21
Q

How do HIV-associated lymphomas present?

A
  1. large B-cell and Burkett’s lymphoma
  2. profound B symptoms
22
Q

What are treatment strategies for HIV associated lymphomas?

A
  1. low dose chemo regimens to decrease immune suppression
  2. concurrent antiretroviral treatment
  3. CNS prophylaxis/ cranial irradiation
23
Q

What is the etiology of HL?

A
  1. infection (EBV)
  2. immunosuppression (HIV, organ transplant)
  3. higher socioeconomic background
24
Q

What is the histology of HL?

A

Reed-Sternberg cells

25
What is the reason Reed-Sternberg cells have an "owl eyes" appearance?
cells have 2 nuclei; possible fusion of reticular cells, B cells, T cells, or both lymphocytes
26
How does HL present?
1. lymphadenopathy (enlarged, painless lymph nodes) 2. "B" symptoms 3. alcohol-induced lymph node pain 4. pruritis
27
What are "B" symptoms?
1. fever >38 degrees C for unknown reason 2. drenching night sweats 3. unexplained weight loss (loss of 10% of body weight in 6 months before diagnosis)
28
How does HL progress?
1. contiguous spread to adjacent lymph nodes 2. more aggressive over time 3. spreads to liver, bone marrow, bone
29
What factors cause a poorer prognosis factor for HL?
1. + "B" symptoms 2. male 3. older age
30
What is the goal of HL treatment?
cure in all patients
31
What agents are used to treat HL?
ABVD: Doxorubicin Bleomycin Vinblastine Dacarbazine
32
What is the treatment of early favorable stage IA and IIA HL?
ABVD (2-4 cycles) + XRT
33
What is the treatment for early unfavorable IB and IIB HL?
ABVD (4-6 cycles) + XRT
34
What is the treatment for advanced favorable IIIA and IVA HL?
ABVD (6-8 cycles)
35
What is the treatment for advanced unfavorable IIIB and IVB HL?
AVBD (6-8 cycles)
36
What is the maximum amount of cycles of AVBD a patient can get?
8 cycles due to Doxorubcin
37
What is the difference between favorable and unfavorable HL?
presence of B symptoms
38
What are side effects with Bleomycin?
1. pulmonary fibrosis 2. hypersensitivity
39
What are side effects with Vinblastine?
1. peripheral neuropathy 2. extravasation 3. constipation
40
What are side effects with Dacarbazine?
1. myelosuppression 2. N/V
41
What are treatments for refractory/ relapsed HL?
1. Brentuximab (antiCD30 monoclonal antibody) 2. alternate chemo 3. stem cell transplant
