Q

What is involved in the grading of cancer?

A

Microscopic assessment of differentiation (how much a cancer resembles the tissue in which it grows); takes into account architectural and nuclear features

Q

What is staging of cancer?

A

its an assessment of size and spread of a cancer,

22
Q

How does the staging of cancer compare to the grading of cancer?

A

Key prognostic factor; more important than grading

23
Q

When is the staging of cancer determined?

A

after final surgical resection of the tumor

24
Q

What is the TNM staging system?

A

T?tumor (size and/or depth of invasion), N?spread to regional lymph nodes; second most important prognostic factor, M?metastasis; single most important prognostic factor

25
Q

In the TNM staging system what is the most important prognostic factor?

A

Metastasis
