1
Q

These types of cancers arise from bone marrow

A

Blood-borne cancers

2
Q

Blood borne cancers: metastasis

A

Hematogenous = already spread through the body, so doesn’t really metastasize

3
Q

What determines if a cancer is leukemia or lymphoma?

A

% of blast cells present

4
Q

Remember: leukemia =

A

Liquid

5
Q

Remember: lymphoma =

A

Solid

6
Q

Lymphoma: originates in this type of tissue

A

Lymphoid

7
Q

Lymphoma: spread via

A

Infiltration

8
Q

Leukemia is a cancer of the ______ system

A

Hematologic

9
Q

Leukemias spread via

A

Invasion and infiltration

10
Q

What are some of the specific conditions that are bloodborne cancers that we discussed?

A
  • multiple myeloma

- non-Hodgkin’s lymphoma

11
Q

What is multiple myeloma?

A
  • cancer of plasma cells in bone marrow

- results in intense bone pain with pathological fx

12
Q

Multiple myeloma survival

A

5 year ~47%

Bone marrow transplants are improving survival rates

13
Q

Why is the 5 year mark important?

A

Time you’re most likely to get a metastasis

14
Q

What is non-Hodgkin’s lymphoma?

A
  • group of lymphomas affecting lymphoid tissue

- has specific large cells present

15
Q

Who gets non-Hodgkin’s lymphoma?

A
  • all ages

- more common in middle age

16
Q

Risk factors for non-Hodgkin’s lymphoma

A
  • male
  • organ transplants
  • autoimmune disease
  • radiation exposure (lots)
  • AIDS
17
Q

non-Hodgkin’s lymphoma disease course

A
  • unpredictable

- widespread

18
Q

Look for these s/s with non-Hodgkin’s lymphoma

A
  • enlarge lymph nodes
  • fever
  • night sweats
  • weight loss
  • bleeding
  • red skin
  • generalized itching
19
Q

non-Hodgkin’s lymphoma: px

A

Variable based upon category

  • indolent
  • aggressive
20
Q

Primary tumors of nerve tissue: types based on location

A
  • intramedullary
  • extramedullary
  • extradural
  • intracranial
21
Q

Primary tumors of nerve tissue: intramedullary

A

Within spinal cord

22
Q

Primary tumors of nerve tissue: extramedullary

A

Outside the SC

23
Q

Primary tumors of nerve tissue: extradural

A

Outside dura mater

24
Q

80% of primary tumors of nerve tissue are of this type

A

Intracranial

  • 60% primary
  • 40% metastases
25
Q

Primary CNS tumors: Do they metastasize outside the CNS? Why or why not?

A
  • rarely
  • no lymphatic path
  • hematologic spread unlikely
26
Q

These are the most common primary malignant tumors

A

Gliomas

27
Q

What are the types of gliomas we discussed?

A
  • Astrocytomas

- Malignant gliomas

28
Q

What are astrocytomas?

A

Benign low grade tumors

29
Q

Astrocytomas are most commonly found in this group

A

Children

30
Q

Example of malignant glioma

A

Glioblastoma (GBM)

31
Q

GBM survival

A

18-24 mos. at most

32
Q

WHO classification of primary brain tumors according to histology

A
  • Graded I-IV to indicate aggressiveness

- IV is most aggressive
