4 - Lymphomas Flashcards
What is lymphoma?
T, B, NK cells (MC’ly B-cells)
“Cancer of the lymph nodes”
Reed-Sternberg cells, think:
Hodgkins lymphoma
Binucleated cells (owl)
MC lymphoma is which type?
Non-Hodgkin
Most are B-cell in origin
Age for NHL?
Affects any age (more frequent in the elderly)
Follicular lymphoma
Indolent / low grade
Diffuse large B-cell lymphoma
Aggressive, high grade
Etiology of NHL
Chronic inflammation
Chronic infection
Exposures
2 main presentations of NHL
Aggressive or indolent
Indolent NHL presentation?
Peripheral lymphadenopathy
Slow-growing
B type sxs UNCOMMON
Hepatosplenomegaly
Aggressive NHL presentation
B sxs COMMON
Rapidly progressive painless lymphadenopathy
Can be either lymph or extranodal dz (i.e. GI, skin, kidneys)
Abdominal pain/mass, think:
Burkitt lymphoma
Labs for NHL
CBC (anemia) Chem LFTs LDH (elevated) Consider HIV/HBV
Definitive dx of NHL
Excisional bx
Ann Arbor staging
For NHL and HL
A - no B sxs
B - presence of B sxs
1- single node or group
2 - two or more sites, same side of diaphragm
3 - both sides of diaphragm
4 - widespread
Txt for NHL
Chemo + Rituximab
R-CHOP or R-CVP
Radiation added to chemo for limited stage dz (I and II)
Surgery (rarely used alone)
Follicular lymphoma txt?
Asymptomatic pts can be left alone until they develop sxs
Prognosis for NHL
Generally, indolent (low-grade) NHL is not curable
Aggressive — generally curable
International prognostic index
Factors leading to poor outcomes
Old
Ann Arbor III or IV
LDH elevated
2+ extranodal sites
HL ages?
1st peak - young adults, mid-twenties
2nd peak - adults > 55
Sxs HL
Painless, SINGLE lymph node (versus chain for NHL)
Spreads in orderly fashion to contiguous nodes
B sxs in 1/3 of patients
Pruritis / excoriations
Pain in lymph node on ETOH ingestion
DDx for HL
Mono Cat-scratch dz Drug reactions NHL Mets
Dx of HL
Excisional biopsy
Reed-Sternberg cells (owl)
Once dx’d, send to heme-onc
Txt of HL
Based on staging
I and II - short course chemo and rads
III and IV - full-course chemo (probably 12+ weeks)
ABVD = MC chemo used for HL
If relapse of HL after chemo+rads:
Stem cell transplant (if good candidate)
Prognosis for HL?
Stage 1/2 - 90% 10-yr survival
Stage 3/4 - 50% 10-yr survival
