Q

What are the symptoms of CML?

A

Triphasic; gradual

Chronic: asymptomatic, may develop fatigue, anorexia, wt loss, fever, excess sweating

Accelerated: splenomegaly causes abd fullness, sx progress w/ bone pain and bruising

Acute “blast crisis”: very pronounced sx

Rarely may get blurred vision, resp distress, priapism

17
Q

In what population will you find Hodgkin lymphoma?

A

Ages 15-45 or over age 50

History of EBV (1/2 of cases)

18
Q

What are the symptoms of Hodgkin lymphoma?

A

painless cervical, supraclavic, and mediastinal lymphadenopathy

possible pain in node after ETOH

A sx: no constitutional sx

B sx: fever, wt loss, night sweats, pruritis, fatigue

19
Q

How are you going to dx Hodgkin lymphoma?

A
  1. r/o other reasons for lymphadenopathy
  2. lymph node bx
20
Q

What will you see in the lymph node bx for Hodgkin’s lymphoma?

A

Reed-Sternberg cells (look like owl eyes)

21
Q

How do you treat Hodgkin lymphoma?

A

Combination chemo

initial tx: radiation therapy

ABVD chemo

22
Q

Who gets Non-Hodgkin lymphoma?

A

Ages 20-40y

Risk with HIV, immudeficiency

23
Q

What are the 2 types of Non-Hodgkins lymphomas?

A

indolent (usually progress to…)

agressive

24
Q

What are the sx of non-hodgkins lymphoma?

A

isolated, painless lymphadenopathy, bone marrow may be involved

may migrate to extralymphatic sites

Burkitt lymphoma comes w/ abd fullness

less likely to have “B” sx

25
Q

How do you diagnose non-hodgkin lymphoma?

A
  1. r/o other causes of lymphadenopathy
  2. Bx lymph nodes
  3. establish staging by CXR, CT, bone marrow bx, LP
26
Q

What will you find in lymph node bx of non-hodgkin lymphoma?

A

I have no effing idea, I just know that you do it.

27
Q

How do you treat non-hodgkin lymphoma?

A

indolent: radiation therapy alone
aggressive: chemo, immunotherapy, autologous stem cell transplantation

28
Q

What exactly is multiple myeloma?

A

malignancy of plasma cells which produces abundant M protein

29
Q

What are the symptoms of multiple myeloma?

A

anemia, bone pain (back/ribs), pathologic fx, infection

rarely renal failure, spinal cord compression, hyperviscosity

30
Q

What will you find on CBC and periph smear of multiple myeloma?

A

pancytopenic with normal cell morphology

31
Q

What studies (other than CBC and smear) will you do for multiple myeloma?

A

Electrophoresis: monoclonal spike

UA: + Bence Jones protein

Radiography: “punched out” regions

32
Q

How do you treat multiple myeloma?

A

Refer to a specialist.

Combo chemo, transplant,

Biphosphonates as adjunt therapy.
