Q

How does EBV cause lymphoma

A

Immunosurveillance of EBV infected cells is impaired

Infected B cells escape regulation + proliferate autonomously

Q

Clinical feature of Hodgkin’s lymphoma

A
  1. Painless cervical lymphadenopathy (rubbery sensation)

Coughs due to mediastinal lymphadenopathy

Sweats, weight loss

Pancpcytopenia if effecting bone marrow

Raised lactose dehydrogenase = worse prognosis as increased cell turnover

Q

How is stage 2B-4 Hodgkin’s treated

A

Combination chemotherapy

19
Q

What drugs are used in chemotherapy

A
  1. Adriamycin
  2. Bleomycin
  3. Vinblastine
  4. Dacarbazine
20
Q

What is the future of Hodgkin’s treatment

A

PET scanning to identify (and reduce amount of treatment given)

21
Q

How would a PET scan be implemented in treatment

A
  1. PET scan -> ABVD - > PET SCAN

If PET (+ve) - Escalated BEACON

If PET (-ve) Randomise ABVD v AVD

22
Q

Late effects of hodgkin’s lymphoma ABVD treatment

A
  1. Infertility
  2. Cardiomyopathy (from anthracyclines)
  3. Lung Damage (Bleomycin)
  4. Vinca alkaloid - peripheral neuropathy
  5. Second Cancers
23
Q

Name a low grade NHL

24
Q

Name a high grade NHL

A

Large B cell lymphoma

25
Name a very high grade NHL
Burkitt's Lymphoma
26
How fast do low grade NHLs grow
Slow
27
Are Low grade NHL curable
No
28
What is the median survival rate of low grade NHL
9-11 years
29
How do we treat Indolent NHL
``` Nothing Alkylating Agents Combination Chemotherapy Purine analogues Monoclonal Antibodies Oral targeted agents Bone Marrow transplants ```
30
Where are high grade NHLs presented
Nodes
31
How often is extra nodal involvement in high grade NHL
1/3 of cases
32
How is High grade NHl treated
Early: Short course chemotherapy + RT (R-CHOP + IFRT) Advanced: Combo chemotherapy + monoclonal antibodies (R-CHOP)
33
What monoclonal antibody do we give patents
Rituximab
34
What does Rituximab target
CD20 expressed on B-cells
35
What compound is given during radio-immunotherapy
Zevalin (Yttrium)
36
What is T-cell engaging therapy
Bi-specific antibodies Target CD19 on B cells CD3 on T cells Directs immune system
37
Name a compound used in T cell engaging therapy
Blinatumomab
38
What does A/B mean in staging
A - No systemic symptoms other than pruritus B - Systemic symptoms: Feber, weight loss and night sweats
39
Ann arbour classification of staging
I - confined to single lymph node II - Involvement of two or more lymph nodes on the same side of diaphragm III - Involvement of nodes on both sides IV - spreads beyond lymph nodes (bone marrow)
40
Side effects of CHEMOTHERAPY
``` Myelosuppresion Nausea Alopecia Infection Infertility ```
41
Complications of radiotherapy
Increased risk of secondary malignancies in lung,breast, stomach Increased tosk of IHD, hypothyroidism and lung fibrosis
42
Stage I vs Stage 2 hodgkins
1 is less than 3 areas involved 2 is more than 3 areas involved
43
Extranodal clinical presentations
Skin | Gut, bowel, bone, cns and lung
44
Why is biopsy done
To determine whether it is hodgkins or non-hodgkin’s
