Q

Pancytopenia seen with leukemia is the result of

A

crowding out from hyperproliferation of blasts

loss of RBC= anemia

Q

CML most common cause

A

translocation of philadelphia
T 9;22

BCR-ABL Oncogene

  1. Stem cell disorder
  2. Characterized bymyeloproliferation
  3. Well-described clinical course

22 is philadelphia

forces continual divisions or premature leukocytes

causes spill over into the blood
splenomegaly

can progress and accelerate in blast crisis

25
CM
Male to female ratio 1.4 to 1 Most frequently b/w ages 40 to 60, but may occur at any age Symptoms related to hypermetabolism: (weight loss, anorexia, night sweats) Splenomegaly is often present Anemia Bruising, epistaxis from platelet dysfunction
26
BCR-ABL causes CML how
turns on tyrosine kinases and leads to build up of premature leukocytes more to liver and spleen causing swelling
27
lab dxs for CML
Lab work up Increased WBC: usually >50K, usually see a complete spectrum of myeloid cells Increased basophils Normocytic anemia Platelet may be increased, normal or decreased Bone marrow is hypercellular PH chromosome positive
28
tx of CML
" Tyrosine kinase inhibitors " Chemotherapy " Interferon " Stem cell transplant -
29
when would we use stem cell transplant for CML
in imatinib failure
30
how do you monitor for pt undergoing tx for CL
check CBC reguarly 6mo Bone marrow biopsy then monitor every three moneths with peripheral blood PCR for BCR-Abl
31
MC type of CLL and when do we see it
B cell Chronic lymphocytic leukemia iv. Peak incidence age 60 to 80 MC in western world
32
tx for CLL
Indolent disease, many patients never need chemotherapy Treat if symptomatic: organomegaly, hemolysis, bone marrow suppression' " Chemotherapy (FCR Therapy - best frontline regimen
33
specific dx for CLL
isolated lymphocytosis w/ leukocytosis > 20K Smudge cells
34
Uncommon B cell lymphoproliferative disorder With a higher prevalence in males
hairy cell leukemia
35
CM of hairy cell leukemia
Peak incidence 40-60 years Clinical presentation: infections, anemia or splenomegaly Lymphadenopathy is very UNCOMMON Pancytopenia is usual
36
tx for Hairy cell
2 CDA or pentostatin | achieve response in >80% patients.
37
tx for non-hodkins
R-CHOP therapy = MC regimen
38
standard dx for lymphoma
biopsy of lymp nodes
39
non-hodkin's lym,phoma dx
Excisional Lymph node biopsy CBC, CMP, LDH, Uric acid, Serum protein electrophoresis CT, CXR for staging Bone marrow biopsy
40
most common non-hodgkin's lymphoma
B cell lymphoma (lymph tumor) comprises 85% of cases T cell and NK cell together comprises 15% of cases.
41
sxs of non-hodgkin's
Lymphadenopathy: Asymmetric painless enlargement of lymph nodes Constitutional symptoms: fever, night sweats, weight loss. Oropharyngeal involvement in 5-10% Infections with extra-nodal involvement: BO, anemia, weakness (spinal cord)
42
reed-sternberg cell is associated with
non-hodgkin
43
describe non-hodkin lymphoma
genetic mutation leads to lymphomas can be nodal or extra-nodal if extranodal can cause GI (MC) BO cause pancytopenia in the bone marrow or spinal cord compression
44
MC form of NHL
indolent follicular lymphoma mean survival is 10 years
45
NHL associated with elevated IgM
Lymphoplasmacytoid lymphoma
46
Second MC type of NHL
Diffuse large B cell lymphoma this one is aggressive
47
2. R-EPOCH
high risk NHL treatment that requires hospitalization
48
types of t cell NHL
Peripheral T cell lymphoma Angiioimmunoblastic lymphadenopathy Mycosis fungoides- causes patches on the skin Sezary syndrome
49
when would you use radiation tx for NHL
consider for stage DLBCL
50
sxs of HL
" Can present at any age: peak incidence in young adults " Mediastinal involvement in 6-11% " Constitutional symptoms can be prominent
51
types of HL
nodular sclerosis mixed cellularity lymphocyte depleted, lymphocyte rich Nodular lymphocyte predominant
52
tx of HL
Treatment " Chemotherapy " Radiation " Both Late effects of Hodgkin's disease and treatment can include secondary lung cancer, myelodysplasia, cardiac disease.
53
Multiple myeloma
Neoplastic proliferation characterized by plasma cell accumulation in the bone marrow, the presence of monoclonal protein in the serum and or urine and related tissue damage.
54
B sxs with HL indicate
Systemic "B” symptoms (advanced disease) (cytokines => Pel-Ebstein fever (cyclical fever that increase & decrease over a period of 1-2 weeks, night sweats), weight loss, anemia, pruritus
55
CM on early HL
firm, non-tender, freely mobile(especially supra clavicular, cervical &mediastinal) .Alcohol may induce lymph node pain.* Hepatosplenomegaly.
56
CD15+, CD30+. "owl-eye appearance" both characteristic of
HL
57
Cancer associated with proliferation of a single clone of plasma cells*
multiple myeloma increase in monoclonal Ab Especially IgG or IgA
58
CM of multiple myeloma
``` Bone pain Recurrent infx Elevated Ca Anemia Kidney failure ```
59
only heme malignancy associated with bone destruction
multiple myeloma
60
dx of multiple myeloma
``` o CBC → anemia and reouleaux formation o Creatinine o ↑ Calcium o ****SPEP: monoclonal M protein spike UPEP --> 24 hr urine - Bence Jones Protein; Bone marrow biopsy ```
61
what bone changes might we see in a pt with multiple myeloma
Skull Radiographs: “punched-out"Ivtic lesions. * Bone scans NOT helpful!
62
tx of multiple myeloma
supportive Autologous stem cell transplant definitive treatment. tPreceded by chemotherapy ex. Thalidomide or alkylating agents ex. Melphalan). Bisphosphonates for bony destruction.
63
Myeloproliferative disorder
Bone marrow disorder characterized by clonal proliferation of one or more hematopoietic components in the bone marrow.
64
three types of myeloproliferative disorder
1. Polycythemia Vera 2. Essential thrombocynthemia 3. myelofibrosis
65
Polycythemia Vera
primarily seen as the increase in RBC but also seen as increase in WBC and platelets
66
Polycythemia sxs
Headache, pruritus, facial plethora, splenomegaly, HTN. Gout can be a result of elevated uric acid. pruritus associated with hot bath
67
tx of polycythemia
Phlebotomy to maintain hct <45 Hydrea can be used for patients who cannot tolerate phlebotomy, or has progressive splenomegaly, thrombocytosis. Interferon is another option. It is less convenient than oral hydrea. Median survival 10-16 years. Transition to myelofibrosis occurs in 30% pts, about 5% progresses to leukemia.
68
hallmark of essential Thrombocynthemia
Sustained increase in platelet count
69
what labs do we see with Thrombocynthemia
ii. Hematocrit is normal iii. Half of patient has JAK-2 mutation o JAK-2 mutation o ↑ Megakaryocytes
70
complications of Thrombocynthemia
iv. Clinical complications: thrombosis and hemorrhage
71
erythormelagia, up to 40% has splenomegaly
polycythemia
72
Polycythemia
o JAK2 mutation o ↓ EPO increased Hct in the absence of hypoxia
73
sustained increase in platelet count is characteristic of this myeloproliferative disorder
essential thrombocytopenia
74
what would you expect to see in the bone marrow of a pt with essential thrombocytopenia
bone marrow shows increase megakaryocytes

excess production of RBCs is characteristics of which myeloproliferative what age gorup do we normally see hthis in
polycythemia 50-60yr median survival 10 years
76
clinical sxs of polycythemia
