lymphoma Flashcards
What is lymphoma? how can it be classified?
- an over proliferation of lymphocytes - aggregate in lymph nodes causing lymphadenopathy
- Hodgkin’s and non-Hodgkin’s
What are some causes of lymphoma?
- unknown
- infection - EBV, H.pylori
- primary immunodeficiency - ataxia telangiectasia
- secondary immunodeficiency - HIV, transplant pts
- autoimmune disorders
Hodgkin’s and non differ. How do they differ in terms of histology and in terms of symptoms and in terms of incidence?
- histology - Reed-sternberg cells (mirror-nuclei)
- symptoms - non-hodgkin is more widespread lymphadenopathy
- Incidence - Hodg = 20s and 70s, Non= 55-60s
What are the clinical features of lymphadenopathy?
- enlarged, painless, non-tender, ‘rubbery’, superficial lymphadenopathy
- nodes increase and decrease randomly
- alcohol induced lymph pain
- constitutional ‘B’ Sx - fever, night sweats, malaise, weight loss, lethargy , puritis
- 2nd and 7th decade peaks of incidence
Signs of hodgkins lymphoma?
- hepatosplenomegaly
- cachexia
- normocytic anaemia, eosinophilia, raised LDH
investigations for lymphoma?
- tissue biopsy - lymph node histology
- bloods
- +/- bone biopsy
- Ct for staging
-GOLD STANDARD - complete excision of a LN and detailed histology
REED-STERNBERG CELLS
What is the staging system for lymphoma?
ANN ARBOR CLASSIFICATION
Stages 1-4
1 = one area of nodes effected
2 = 2 or more on one side of the diaphragm
3= lymph nodes of both sides of the diaphragm affected
4= beyond lymph node spread (liver, bones marrow)
then A or B
A= no B symptoms
B= B symptoms
How we treating hodgkins?
1-2A= chemo + radio 2B-4= just chemo
combination chemo is ABVD: adriomycin bleomycin vinblastine decarbazine
HoDgkins = abvD (non = RCHOP)
SE = infertility, cardiomyopathy, lung damage, peripheral neuropathy, secondary cancers, psychological issues
Tell me about some the types of non-hodgkins lymphoma?
- they are all lymphomas that DON’T have reed-sternberg cells
- they often have extra nodal involvement such as:
- skin nodes - cutaneous T cell lymphoma
- gastric lymphoma - MALT (mucosa associated lymphoid tissue) - non-MALT gastirc (bad)
- small bowel lymphoma
What’s the classic Non-hodkins treatment?
R-CHOP (becuase it’s nOn-hodgkins)
- Rituximab
- Cyclophosphomide
- hydroxydaunorubicin
- oncovin
- prednisolone
What are some acute presentations of lymphoma?
- infection
- SVC obstruction leading to facial swelling
- ‘fullness of the head’
- dyspnoea
- blackouts
