Q

Symptoms to ask about ?breast disease

A

Lumps: does the lump fluctuate in size? is it getting bigger? does it fluctuate with menstrual cycle? does the lump move when you press it? any skin changes over where the lump is or elsewhere? any thickening of the skin? any other lumps?

Symmetry change: has there been a change in symmetry? any swelling?

Nipple symptoms: any discharge? colour of discharge? bloody? any skin changes around the nipple such as dry skin? itchy? has the nipple changed shape/inverted?

Pain and temperature: is there any pain in the breast? has it been hot to touch?

Q

What is the triple assessment?

A

Clinical assessment: symptoms, risk factors, family history particularly age, HRT and medications

Imaging assessment - if <40 USS, if >40 mammogram

Needle biopsy : core biopsy allows you to test for receptors etc as big chunk, fine needle aspiration of lymph nodes allows you to check for malignancy to see if axillary node clearance is indicated.

Q

Pharamcology tamoxifen

A

Tamoxifen is a selective oestrogen receptor modulator (SERM).

It either blocks or stimulates oestrogen receptors, depending on the site of action.

It blocks oestrogen receptors in breast tissue, and stimulates oestrogen receptors in the uterus and bones.

This means it helps prevent osteoporosis, but it does increase the risk of endometrial cancer.

Q

pharmacology aromatase inhibitors such as Anastrozole

A

Aromatase is an enzyme found in fat (adipose) tissue that converts androgens to oestrogen. After menopause, the action of aromatase in fat tissue is the primary source of oestrogen. Aromatase inhibitors work by blocking the creation of oestrogen in fat tissue

Q

what drug is used for HER2 +ve breast cancer?

what i main complication you need to monitor?

A

Trastuzumab (Herceptin)

a monoclonal antibody that targets the HER2 receptor. It may be used in patients with HER2 positive breast cancer. Notably, it can affect heart function; therefore, initial and close monitoring of heart function is required.

Pertuzumab (Perjeta)
Neratinib (Nerlynx)

Q

when is ‘neoadjuvanant’ chemotherapy used?

A

to downstage a primary lesion or after surgery depending on the stage of the tumour, for example, if there is axillary node disease - FEC-D is used in this situation.

A key reason for considering neo-adjuvant chemotherapy in breast cancer is to try to downsize the tumour before surgery and allow breast conserving surgery rather than mastectomy

Pathophysiology duct ectasia

A

Duct ectasia is a dilatation and shortening of the terminal breast ducts within 3cm of the nipple. It is common and the incidence increases with age. Associated with smoking

40
Q

management of duct ectasia

A

Patients with troublesome nipple discharge may be treated by microdochectomy (if young) or total duct excision (if older).

41
Q

Lumpiness

A

Mammogram:
M1 = normal
M2= benign
M3 = uncertain
M4 = suspicious
M5 = malignant

48
Q

whata re the three types of receptors breast cancer may have?

A

There are three types of receptors:
Oestrogen receptors (ER)
Progesterone receptors (PR)
Human epidermal growth factor (HER2)

49
Q

what is ductal carcinoma in situ?

A

Pre-cancerous or cancerous epithelial cells of the breast ducts
Localised to a single area
Often picked up by mammogram screening
Potential to spread locally over years
Potential to become an invasive breast cancer (around 30%)
Good prognosis if full excised and adjuvant treatment is used

50
Q

what is lobular carcinoma in situ?

A

A pre-cancerous condition occurring typically in pre-menopausal women
Usually asymptomatic and undetectable on a mammogram
Usually diagnosed incidentally on a breast biopsy
Represents an increased risk of invasive breast cancer in the future (around 30%)
Often managed with close monitoring (e.g., 6 monthly examination and yearly mammograms)

51
Q

what is invasice ductal carcinoma NST? what does NST mean?

A

NST means no special/specific type, where it is not more specifically classified (e.g., medullary or mucinous)
Also known as invasive breast carcinoma of no special/specific type (NST)
Originate in cells from the breast ducts
80% of invasive breast cancers fall into this category
Can be seen on mammograms

52
Q

what is invasive lobular carcinoma

A

Around 10% of invasive breast cancers
Originate in cells from the breast lobules
Not always visible on mammograms

53
Q

what is inflammatory breast cancer? what is the pathophysiology of the inflammation?

A

Presents similarly to a breast abscess or mastitis
Swollen, warm, tender breast with pitting skin (peau d’orange)
Does not respond to antibiotics
Worse prognosis than other breast cancers

Pathophysiology
Cancerous cells block the lymph drainage resulting in an inflamed appearance of the breast. This accounts for around 1 in 10,000 cases of breast cancer.

54
Q

what is pagets disease of the nipple?

A

Looks like eczema of the nipple/areolar
Erythematous, scaly rash
Indicates breast cancer involving the nipple

May represent DCIS or invasive breast cancer
Requires biopsy, staging and treatment, as with any other invasive breast cancer

55
Q

how does pagets disease differ from normal eczema of the nipple?

A

Paget’s disease involves the nipple primarily and only latterly spreads to the areolar

(the opposite occurs in eczema).

56
Q

options for reconstruction

A

MASTECTOMY
- Immediate reconstruction, done at the time of the mastectomy
- Delayed reconstruction, which can be delayed for months or years after the initial mastectomy

  • Breast implants (inserting a synthetic implant)
  • Flap reconstruction (using tissue from another part of the body to reconstruct the breast eg lattismus dorsi flap

BREAST-CONSERVING
- may not be necessary

  • Partial reconstruction (using a flap or fat tissue to fill the gap)
  • Reduction and reshaping (removing tissue and reshaping both breasts to match)
57
Q

when should a fibroadenoma be biopsied

A

A size of greater than 4cm attracts a recommendation for core biopsy to exclude a phyllodes tumour.

58
Q

natural history of fibroadenoma

A

The natural history of fibroadenomas is that 10% will increase in size, 30% regress and the remainder stay the same.

59
Q

pathophysiology fibroadenoma

A

Under the age of 25 years the breast is usually classified as undergoing development. Lobular units are being formed and a dense stroma is formed within the breast tissue. This may result in the development of fibroadenomas.

60
Q

management of cysts

A

Symptomatic cysts may be aspirated and following aspiration the breast re-examined to ensure that the lump has gone.

61
Q

most common organism causing infective mastitis

A

Staphylococcus aureus

62
Q

complication mastitis

A

If left untreated, mastitis may develop into a breast abscess. This generally requires incision and drainage.

63
Q

advice breastfeeding/expressing if on flucloxacillin for mastitis

A

Breastfeeding or expressing should continue during treatment.

64
Q

what breast diseases are associated with smoking

A

periductal mastitis and abscesses

duct ectasia

65
Q

fat necrosis pathophysiology

A

Fat necrosis causes a benign lump formed by localised degeneration and scarring of fat tissue in the breast. It may be associated with an oil cyst, containing liquid fat. Fat necrosis is commonly triggered by localised trauma, radiotherapy or surgery, with an inflammatory reaction resulting in fibrosis and necrosis (death) of the fat tissue. It does not increase the risk of breast cancer.

66
Q

how might you need to distinguish between breast cancer and fat necrosis

A

Ultrasound or mammogram can show a similar appearance to breast cancer. Histology (by fine needle aspiration or core biopsy) may be required to confirm the diagnosis and exclude breast cancer.

67
Q

management fat necrosis

A

After excluding breast cancer, fat necrosis is usually treated conservatively. It may resolve spontaneously with time. Surgical excision may be used if required for symptoms.

68
Q

pathophysiology fibrocystic breast change

A

The connective tissues (stroma), ducts and lobules of the breast respond to the female sex hormones (oestrogen and progesterone), becoming fibrous (irregular and hard) and cystic (fluid-filled). These changes fluctuate with the menstrual cycle.

69
Q

how does symptoms of fibrocystic breast change fluctuate with the menstrual cycle

A

Symptoms often occur prior to menstruating (within 10 days) and resolve once menstruation begins. Symptoms usually improve or resolve after menopause.

70
Q

lipomas on examination

A

Soft
Painless
Mobile
Do not cause skin changes

71
Q

what are lipomas

A

Lipomas are benign tumours of fat (adipose) tissue. They can occur almost anywhere on the body where there is adipose tissue, including the breasts

72
Q

management lipoma

A

They are typically treated conservatively with reassurance. Alternatively, they can be surgically removed.

73
Q

pathophysiology galactocele

A

Galactoceles occur in women that are lactating (producing breast milk), often after stopping breastfeeding. They are breast milk filled cysts that occur when the lactiferous duct is blocked, preventing the gland from draining milk. They present with a firm, mobile, painless lump, usually beneath the areola. They are benign and usually resolve without any treatment. It is possible to drain them with a needle. Rarely, they can become infected and require antibiotics.

74
Q

How should you manage a pt w breast cancer with no palpable axillary lymphadenopathy. A pre-operative ultrasound of the axillary nodes comes back negative

A

Sentinal node biopsy during surgery

75
Q

Conplication of axillary node clearance

A

Functional arm impairment

An axillary node clearance can cause functional arm impairment from either the lymphedema (which causes swelling and limited range of motion) or nerve damage given the proximal nature of the nerves that run from the axilla to the lymph nodes being dissected. The specific nerves in question include the long thoracic nerve, axillary nerve, musculocutaneous nerve and radial nerve

76
Q

how to know what to do about axilla with +ve sential node biopsy

A

In patients with breast cancer undergoing breast conserving surgery with adjuvant radiotherapy if, at sentinel node biopsy, less than 3 involved nodes are found then no further management of the axilla is required
