Breast lump - usually painless
Pau de orange

Q

How do we diagnose breast cancer?

A

Use a tripple assessment:

  1. clinical score 1-5: normal-clearly malignant
  2. imaging score 1-5
  3. biopsy score 1-5

Q

What are the surgical options for pts with breast cancer?

A
  1. Breast conservation - lumpectomy or wide excision: always give radiotherapy afterwards
  2. Mastectomy

Both procedures will involve some surgery to the axilla

Q

What factors would mean that breast conservation surgery can be done instead of mastectomy?

A
  • Small tumour relative to breast size usually <25%
  • Neoadjuvant chemotherapy - where the pt is given chemo before surgery. this can shrink the tumour making it suitable for lumpectomy
  • No previous radiotherapy to the breast
  • Pt choice

Q

What factors would mean that a mastectomy would be the preferred option over breast conservation?

A
  • large tumour relative to breast size
  • more than one tumour in the same breast esp if in different quadrants
  • patient choice

Q

What type of axillary surgery will a pt with clinically normal nodes undergo?

A

Limited axillary surgery
Sentinel node biopsy
Remove between 1-4 glands under the arm
Identify which nodes are most likely to have cancer in by using a radioactive dye or blue dye

Q

What are the advantages of full axillary clearance?

Q

What are the disadvantages of limited axillary surgery?

A

May need clearance or radiotherapy

20
Q

What do you do if you do a sentinel node biopsy after surgery and you find no axillary disease?

A

No further axillary surgery

21
Q

What do you do if you find large volume axillary disease after surgery?

A

Second axillary clearance

22
Q

What do you do if you find small volume axillary disease after surgery with a low risk cancer?

A

No further treatment

or radiotherapy to axilla

23
Q

What are the two most common types of breast cancer?

A

Ductal

Lobular

24
Q

How does ductal carcinoma feel?

25
How does lobular carcinoma feel?
Diffuse and difficult to feel
26
How are breast cancers graded?
1-3 Grade 1 - slow growing, well differentiated and good prognosis Grade 3 - looks nothing like breast tissue
27
How are breast cancers staged?
``` TNM staging Tumour: T0 - no evidence of a primary T1 - <2cm T2- 2-5 cm T3 - >5cm T4 - extends to chest wall or skin or inflammatory ``` N0 - no nodes N1 - mobile nodes N2 - fixed nodes N3 - internal mammary nodes M0 - no mets M1 - mets Stage 1 - disease confined to the breast Stage 2 - breast and axilla Stage 3 - Locally advanced Stage 4 - mets
28
What is the Nottingham prognostic index?
Looks at patients who have stage 1 and stage 3 cancer and takes into account heir grade, nodes and size to identify those with poor prognosis if only offered surgery Can offer these women adjuvant chemo and hormone therapy
29
What are the 4 types of receptors that can be present in breast cancer?
ER - oestrogen receptor Her-2 - herceptin receptor PgR - progesterone receptor Ki67- marker of proliferation
30
What is the importance of identifying the type of receptor on breast cancer cells?
Prognosis | Guides treatment options
31
What is Predict?
An online calculator tool that takes into account age, tumour size, grade, stage and receptor type and assesses response and prognosis following different treatment options
32
What is oncotype dx?
A multi-gene array - looks for 21 different genes which have prognostic significance and derives a score to see whether she would benefit from chemo or not
33
What are the adjuvant treatments for breast cancer?
``` Tamoxifen Aromatase inhibitors Radiotherapy Chemotherapy Traztuzumab Bisphosphonates ```
34
What is tamoxifen and who is it given to?
Tamoxifen is an inhibitor of the oestrogen receptor on breast cells All pts with ER+ disease who are pre-menopausal
35
What are aromatase inhibitors and who are they given to?
Inhibit the aromatase enzyme responsible for converting androgens to oestrogens in post-menopausal females Only effective in post-menopausal women as it doesn't affect the ovaries production of oestrogen and is better than Tamoxifen after the menopause All pts with ER+ disease who are post-menopausal
36
Who is radiotherapy given to?
All women who have a lumpectomy Women with aggressive disease after mastectomy Used in axilla of pts with positive sentinel node biopsy after surgery
37
Who is chemotherapy given to?
Aggressive disease phenotype: Her 2+ or ER-, grade 3 or node positive, large tumour size, young age So only for women with high risk disease
38
What is Traztuzumab and who is it given to?
A Her-2 targeted therapy used in conjuction with another Her-2 targete therapy called Pertuzamab All Her2+ disease
39
Who gets bisphosphonates and why are they used?
High risk cancer in post-menopausal women with Her2+ disease Improves survival from cancer as reduces the rate of bone mets
40
Are Her 2+ cancers aggressive or not?
They are very aggressive and are well-known markers of poor prognosis and commonly metastesizes to the brain
41
How long is tamoxifen given for?
5 or 10 years
42
What are the side effects of tamoxifen?
``` Hot flushes Nausea Vaginal bleeding Thromboses Endometrial cancer ```
43
What are the side effects of aromatase inhibitors?
Hot flushes | Reduced bone density
44
What are the side effects of trastuzamab?
can cause heart failure
45
When is wire localisation used?
For impalpable cancers that will be operated on
