Invasive lobular carcinoma
Ductal carcinoma in-situ
Lobular carcinoa in-situ

23
Q

Which type of breast cancer can demonstrate “comedo necrosis”?

A

DCIS

24
Q

What is Paget’s disease of the nipple?

A

An eczematoid change of the nipple associated with an underlying brest malignancy

25
Q

When is the mammography screening in the UK?

A

Age 43-73 every 3 years

26
Q

Recall the 2ww, consider 2ww and no 2ww criteria for breast Ca

A

2ww:
>30y, unexplained breast lump
>50y, any breast changes

Consider 2ww:
- Skin changes suggestive of breast Ca
- >30y, unexplained lump in axilla

Non-2ww:
<30y, unexplained breast lump

27
Q

What makes up the triple assesment for breast Ca?

A
  1. History and exam
  2. Imaging (Mammography >35, USS <35, MRI if implants)
  3. Pathology (FNA, core biopsy)
28
Q

Describe the lymphatic drainage of the breast

A

75% to lateral axillary nodes
25% to parasternal nodes and opposite breast

29
Q

Which receptors are all invasive breast cancers tested for?

A

Oestrogen receptor
Progesterone receptor
Her2 receptor

30
Q

What receptors are positive/ negative in low vs high grade breast cancers?

A

Low grade: ER+, PR+, Her2-

High grade: Er-, PR-, Her2 pos

31
Q

What is the receptor status of a basal-like carcinoma of the breast?

A

ER, PR and Her2 neg

32
Q

How does surgery for breast Ca differ depending on whether there is clinical axillary lymphadenopathy or not?

A

If there is CAL: axillary node clearance

If no CAL: USS and SLNB +/- axillary node clearance

33
Q

Recall 4 types of breast tumour that can be managed using wide local excision rather than mastectomy

A

Solitary lesion
Peripheral tumour
Small lesion in large breast
DCIS <4cm

34
Q

What are the indications for post-operative radiotherapy in breast Ca?

A

Following any wide local excision
Following a mastectomy IF:
- T3 or T4 OR
- 4 or more pos LNs

35
Q

When is hormone therapy indicated in breast Ca?

A

If ER+

36
Q

What options are there for hormone therapy in breast Ca?

A
