  • Inflammatory breast cancer
46
Q

A

-> Mammogram every 3 years to women aged 50-70.

47
Q

How does breast screening differ for higher risk women

A
  • Annual mammogram
  • Chemoprevention (Tamoxifen if premenopausal, anastrozole if postmenopausal)
  • Risk reducing bilateral mastectomy or bilateral oophorectomy
48
Q

2 week wait referral for suspected breast cancer

A
  • An unexplained breast lump in patients aged 30 or above
  • Unilateral nipple changes in patients aged 50 or above (discharge, retraction or other changes)
49
Q

Assessment following 2 week wait referral

A
  • Clinical assessment (history and examination)
  • Imaging (ultrasound or mammography)
  • Biopsy (fine needle aspiration or core biopsy)
50
Q

Imaging used in breast cancer

A
  1. USS = younger women
  2. Mammograms = older women, better at picking up calcifications
  3. MRI scans = higher risk women and further assessing features of a tumour
51
Q

What is done in breast cancer surgery if the initial USS does not show any abnormal nodes ?

A

Sentinel lymph node biopsy

52
Q

What 3 types of receptor may be seen in breast cancer ?

A
  • Oestrogen receptors (ER)
  • Progesterone receptors (PR)
  • Human epidermal growth factor (HER2)

Triple negative breast cancer = no cancer cells express any. of these receptors

53
Q

what is gene expressing profiling >

A
  • Assessing which genes are present within breast cancer on histology sample
  • Done for women with early breast cancers that are ER positive but HER2 & lymph node negative
  • Helps guide whether to give additional chemotherapy as predicts the risk of breast cancer recurrence as a distal met
54
Q

Common breast cancer mets

A

L : Lungs
L : Liver
B : Bone
B : Brain

55
Q

Explain the surgical options for breast cancer

  • Shrinking of breast tissue
  • Long term skin colour changes (usually darker)
57
Q

3 types of chemotherapy scenarios

A

2. Aromatase inhibitors for postmenopausal women (e.g., letrozole, anastrozole or exemestane)

60
Q

Method of action of tamoxifen and therefore its SE

A
  • Blocks oestrogen receptor in breast tissue and stimulates them in the uterus and bones
  • Helps prevent osteoporosis BUT increases risk of endometrial cancer
61
Q

Give 3 targeted treatments for women with HER2 positive breast cancer

A
  1. Trastuzumab (Herceptin) is a monoclonal antibody that targets the HER2 receptor.
  2. Pertuzumab (Perjeta) is another monoclonal antibody that targets the HER2 receptor.
  3. Neratinib (Nerlynx) is a tyrosine kinase inhibitor, reducing the growth of breast cancers.
62
Q

SE of herceptin

A
  • Can affect heart function and therefore pots require initial and close monitoring of heart function
