21
Q

t/f survival is long for cll patients with only lymphocytosis

A

true

22
Q

treatment for cll

A

low risk: just observe
high risk, fit: transplantation or FCR chemo
high risk, frail: don’t be agressive

23
Q

t/f patients with mutation in p53 of 17p have better diagnosis

A

false

24
Q

hallmark of hodgkin’s lymphoma

A

reed sternberg cells with owl’s eye appearance

25
Q

symptoms of lymphomas

A

bulky lymph nodes

b symptoms: fever, night sweats, weight loss

26
Q

stage 1 lymphoma

A

single lymph node

27
Q

stage 2 lymphoma

A

> 1 lymph node as long as it’s in one side of the diaphragm

28
Q

stage 3 lymphoma

A

lymph nodes on both sides of diaphragm

29
Q

stage 4 lymphoma

A

involves bone marrow, liver, or other extranodal sites

30
Q

A vs B in lymphoma

A

A: no other symptoms
B: other symptoms

31
Q

diagnostics of lymphomas

A

morphology, cytochemical, immunophenotyping, flow cytometry, imaging (ct form brain to pelvis, pet to see active LNs)
serum chemistry

32
Q

treatment for diffuse large b cell lymphoma

A
RCHOP
Rituximab
Cyclophosphamide
Hydroxydaunomycin
Oncovin
Prednisone

bulky tumor = + radiotherapy

33
Q

early stage hodgkin lymphoma treatment

A

short course chemo

moderate dose radiation targeting of lns

34
Q

nodular lymphocyte predominant hodgkin lymphoma treatment

A

radiation alone, good prognosis

35
Q

advanced stage HL treatment

A

chemo is main, limited role for radiation

36
Q

chemo drugs for HL

A
ABVD
Adriamycin
Bleomycin
Vinblastine
Dacarbazine
37
Q

treatments to consider in HL

A

autologous stem cell transplant

immune checkpoint inhibitors

38
Q

treatments for refractory HL

A

anti cd30 antibody: brentuximab vedotin

39
Q

disorders involving plasma cells

A

myeloma
amyloidosis
waldenstrom’s macroglobulinemia
heavy chain disease

mature b-cell neoplasms = loss of control over igg production

40
Q

symptoms of multiple myeloma

A

CRAB
Calcium is high due to increased bone resorption
Renal failure due to immunoglobulins deposited into kidney
Anemia
Bone pain due to bone resorption

41
Q

diagnosis for multiple myeloma

A

clonal bone marrow cells >/= 10% plasma cells
+ CRAB symptoms
+ other markers like increase in serum free light-chain

42
Q

smear of multiple myeloma cells

A

numerous myeloma cells

normal to have eccentric nucleus and perinuclear clearing

43
Q

skeletal findings in multiple myeloma

A

lytic lesions due to increased osteoclast activity

44
Q

electrophoresis results in multiple myeloma

A

keeps producing one specific type of protein

45
Q

pathophysio of multiple myeloma

A

figure 12

46
Q

high risk multiple myeloma patients

A

have deletion of 17p (tp53 gene)

47
Q

treatment for multiple myeloma

A

chemo followed by autologous stem cell transplant

48
Q

drug given to MM patients eligible for transplant

A

bortezomib (proteosome inhibitor)
- cleans up all cellular protein debris

steroids
immunomodulatory drugs: thalidomide, dexamethasone

49
Q

t/f stem cells are harvested after induction in MM

A

true

50
Q

treatment for MM patients not eligible for transplant

A

give bortezomib + melphalan

51
Q

course of multiple myeloma

A
  • many relapses

- still uncurable
