Q

Outling the Imaging stage of the Breast Triple Assessment

(MRI can be useful in assessing lobular breast cancers + response to neoadjuvant therapy. Whilst it has high sensitivity, it has a low specificity)

A

Mammography (can be done w/ Contrast)

  • Compression views of breast across 2 views
  • Allows to detect Mass Lesions or Micro-calcifications

USS;

  • More useful in Women <35 and Men (due to tissue density)
  • Also routiney used during core biopsies

Q

Outline the Biopsy/ Histoloy stage of the Breast Triple Assessment

(Required of any suspicious mass/ lesion presenting to the clinic, most commonly via core biopsy)

A

Core Biopsy;

  • Provides histology, allowing differentiation between Invasive and In-situ Carcinoma
  • Higher Sensitvity + Specifcity than FNA

FNA Biopsy; (Fine needle aspiration)

  • Provides Cytology
  • Used if Recurrent Cystic disease, to relieve symptoms

Q

Malignancy suspicion is graded at each stage

Outline how an Overall Risk Index is created by Triple Assessment, to determine if;

  • Benign/ Malignant
  • Further intervention+biopsy needed
A

P= Examination Score, B= Histology score
Imaging (Mammography/ USS) Score= M/U

1= Normal
2= Benign

27
How do Breast Carcinomas-in-situ usually present?
Usually Asymptomatic, found incidentally/ by screening
28
Carcinoma of the breast is the most common cancer in the Western world and accounts for 20% of all cancers in women in the UK, with 1 in 10 women developing breast cancer in their lifetime List the classes of Invasive Breast Carcinoma
- IDC, Invasive Ductal Carcinoma (75-85%) - ILC, Invasive Lobular Carcinoma (10%) Others (5%) - E.g Medullar or Colloid Carcinoma
29
Why is the division of Breast carcinomas into Ductal and Lobular WRONG? Why is it still used as a classification
Almost all breast carcinomas arise in the Terminal Duct Lobular Unit The 2 subtypes behave differently
30
IDCs are the most common breast carcinomas (80% of all cases) List their further classifications Which 3 are Well-circumscribed and show the best Prognoses?
Further subtypes of IDCs; - Tubular* - Cribriform* - Papillary* - Mucinous/ Colloid - Medullary
31
ILCs are; - The 2nd most comon type of breast cancer (10% of all invasive cancers) - More common in older women Describe them
Characterised by diffuse/ stromal pattern of spread, that makes detection harder (hence by diagnosis, tumors are quite large)
32
List RFs for Invasive Breast Cancer | Similar to Breast Carcinomas In-Situ

35
Outline Investigations for Invasive Breast Cancer | Managment is Extensive+Variable
Gold standard: Triple Assessment
36
Which factors affect the Prognosis of Invasive Breast Cancer
- Nodal status (most important) - Size - Grade - Vascular Invasion - Receptor status (all malignancies should be checked for ER, PR and HER2 status, influencing treatment)

42
Outline Investigations for Paget’s Disease
Biopsy to confirm, entire nipple may be removed for histology exam Breast+Axilla exam (strong link to cancer) May need Mammograms, USS, MRI Breast
43
Outline Management of Paget’s Disease
1st line: Surgical - Type depends on how advanced underlying cancer is - IN ALL CASES, Nipple+Areola removed Radiotherapy may be needed if underlying malignancy

Dilation + Shortening of major lactiferous ducts
60
How may Mammary Duct Ectasia present?
- Green/ Yellow Nipple discharge - Palpable mass - Nipple retraction (often slit-like) (Any blood stained discharge requires Triple Assessment)
61
Outline Investigations for Mammary Duct Ectasia
Mammography; - Dilated Calcified ducts w/o any features of malignancy On Biopsy; - Mass contains multiple plasma cells on Histology (AKA ‘Plasma Cell Mastitis’)
62

66
Outline Fat Necrosis Management
Self-limiting Only need Analgesia + Reassurance
67
What is Gynaecomastia? How common is it? (1% of cases-> Breast cancer)
Males develop breast tissue, due to imbalanced Oestrogen and Androgen activity At least 33% of men experienc it in their lifetime (Usually fully reversible)
68
Compare the 2 types of Gynaecomastia
Physiological; - Mostly in teens, due to Delayed Testosterone surge relative to Oestrogen - Less commonly, in Elderly due to decreasing Testosterone w/ increasing age Pathological; - Changes in Oestrogen:Androgen activity ratio
69
List 4 mechanisms of Pathological Gynaecomastia | Changes in Oestrogen:Androgen activity ratio

71
Outline Investigation + Results for Gynaecomastia
Testicular exam Tests: Only if cause unknown; - LFTs, U&Es, Hormone profile if these are normal High LH, Low Testosterone= Testicular failure Low LH, Low Testosterone= Increased Oestrogen High LH, High Testosterone= Androgen resistance or Gonadotrophin-secreting malignancy

Very low malignant potential Can be left alone with follow-ups over a 2yr period Diameter >3cm or Pt preference
76
Describe Ductal Adenomas
Benign Glandular tumour Usually in Older Females Lesions are Nodular, Can mimic Malignancy (So most cases undergo Triple Assessment)
77

Usually in Females 40–50 Mostly in Subareolar region (Usually <1cm from Nipple) Bloody/ Clear nipple discharge Larger ones can present as a mass initially
78
How are Intraductal Papillomas investigated? How are they managed? (Breast cancer risk only increased with Multi-ductal papillomas)
Can appear similar to Ductal Carcinomas on Imaging, so usually need Biopsy Some cases may be excised, most treated with Microdochectomy
79
Describe Lipomas, their prognosis and treatment
Soft, Mobile adiopose tumour Low malignant potential Usually only removed if; - Significantly enlarging - Compressive symptoms - Aesthetic issues
80
What are Phyllodes Tumours? | Describe them
Rare Fibroepithelial tumours, made of Epithelial+Stromal Tissu Large, Grow rapidly and occur in Older people
81
Outline Phyllodes Tumour Investigation, Management and Prognosis (Phyllodes means ‘Leaf’, due to characteristic leaf-like fibrous tissue projections on microscopy)
Hard to differentiate from Fibroadenomas clinically and microscopically Most Phyllodes Tumours; - Widely Excised - Mastectomy if Large lesion - 33% of Phyllodes Tumours have malignant potential - 10% recur after excision
82
How may Benign Breast Tumours present? Investigation+Management: Triple assessment, Reassurance+Routine check-ups. Excised if can’t exclude malignancy
Variable, but generally; - Mobile, Smooth borders Can have Multiple Lumps Pain/ Discomfort if they grow (Malignant: Single lump, Craggy surfaces, Firm, Fixed to different tissue layers)
83
What’s the main Ddx for Gynaecomastia
Pseudogynaecomastia: Adipose in breast region, assosciated with being overweight (Can be tested by pinching to see if there is an obvious disc of breast tissue present, however if not palpable then further imaging and/or histology may be required to definitively exclude)
84
Niipple retraction is often benign Compare the usual causes of Slit-like and Circumferential
Slit-like: Duct Ectasia | Circumferential: Carcinoma
85
How would Fibrocystic change present What condition could this be associated with
Painful thickening, rather than a lump Associated with Breast Cysts
86
What are Cooper’s ligaments? What can happen when they lengten/ loosen/ get damaged? What can happen when they tighten/ constrict (due to cancer, fat atrophy or necrosis)
Connect tissue around chest muscle to under the skin of the breast Sagging/ drooping Puckering/ Dimpling
