38
Q

What is clinical staging?

A

PE
Radiographs
Isotopic scans
CT scans

39
Q

What is pathologic staging?

A

Palpation
Resection of lymph nodes
Inspection and biopsy.

Generally the info you obtain during a surgical procedure.

40
Q

What is the first step in managing a cancer pt?

A

Determining the extent of the disease, aka staging it.

41
Q

What is the common way to stage a cancer?

A

TNM
Tumor
Node
Metastasis

42
Q

What is each component of TNM associated with?

A

Tumor is to check the size of the main tumor and if it has spread nearby.

Node is whether it has spread to regional lymph nodes.

Metastasis is whether it has spread beyond its region to other organs.

43
Q

What kind of cancers cannot be staged by something like TNM?

A

Hematopoietic cancers, like leukemia or lymphoma.

44
Q

A

A patient’s likelihood of being able to cope with the physiologic stresses of cancer treatment.

45
Q

What are some markers for physiologic reserve?

A

Age
Karnofsky performance status
Eastern cooperative oncology group performance status (ECOG)

46
Q

How is Karnofsky performance status graded?

A

0-100, 100 being normal.

Has to do with ability to take care of oneself physically.
