Q

Staging is important because

A

it helps in treatment planning
assists the evaluation of treatment modalities
aids prognosis
enables patients to b compared between different cancer centres internationally
research and clinical trials

21
Q

M0

A

no metastasis

22
Q

M1

A

Metastasis present

23
Q

Clinical staging

A

cTNM

based on evidence before treatment

24
Q

Pathological staging

A

pTNM
based on evidence aquired from surgical procedure
can be restaged

25
Q

yTNM

A

stage assesed after chemo or radiation therapy

neoadjuvant therapy

26
Q

rTNM

A

stage for a recurrent tumour after some time disease free

27
Q

aTNM

A

stage determines at autopsy

28
Q

Stage grouping

A

To predict survival rates

so its a uniform grouping system

29
Q

stage 0

A

carcinoma in situ

30
Q

stage 4

A

tumour with distant metastasis

31
Q

Ann Arbor Staging system

A

used for lymphomas

32
Q

Childhood cancers staged using

A

COG and TNM

33
Q

cervix,uterus,ovary,vagina and vulva cancer staging

A

FIGO

34
Q

MAC - Dukes and Modified Aster-collier

A

for colorectual cancer

35
Q

Grading tumour

A

based on differentiation
can be well differentiated and resembles parent tissue and arranged in a similar pattern to parent tissue
Undifferentitated - no resemblance to parent tissue
graded via degree of malignancy

36
Q

Grade 1

A

well differentiated

37
Q

Grade 2

A

Moderately differentiated

38
Q

Grade 3

A

Poorly differentiated

39
Q

Grade 4

A

Undifferentiated

40
Q

Gleason score

A

prostate
grade 1 - no cancer
grade 2 - rare
more than one grade of cancer so the grade of the two most common are added together

41
Q

Scharf Richardson Bloom System

A

Breast

42
Q

Need to be aware of when grading

A

Presence of giant cells, Variation in size, shape and stain of nuclei and number of abnormal mitoses

43
Q

grading sample

A

must be taken from edge of tumour, it is the most evolved in the tumout at that point

44
Q

least differentiation

A

greater mitotic rate and greater number of abnormal mitoses

45
Q

why is grading important

A

to know the behaviour of the tumour, determine choice of treatment, prognosis

46
Q

higher gleason score

A

more active the cancer

47
Q

ISUP grading system

A

simpler

48
Q

ISUP Grade 1

A

gleason score less than 6

low risk

49
Q

ISUP Grade 2

A

gleason score 7

intermediate favourable

50
Q

ISUP Grade 3

A

gleason 7

intermediate unfavourable

51
Q

ISUP 4

A

gleason 8

high risk

52
Q

ISUP 5

A

gleson 9-10

high risk
