Q

What is the appropriate screening for breast cancer?

A
  • 40+ yo in good health = yearly mammograms
  • Clinical breast exam about every 3 years for women in their 20s and 30s
  • If family history is positive, then 10 years earlier than the age of the youngest affected.

  2. Shape
  3. Texture
  4. Tenderness
  5. Location
  6. Fixation
17
Q

When finding/examining a discharge, what are we looking for?

A
  1. Color
  2. Quality
  3. Pressure
18
Q

When finding/examining a nodes, what are we looking for?

A
  1. Axillary

2. Supraclavicular

19
Q

What imaging techniques are used for breast cancer visualization?

A
  1. Mammogram
  2. US and Bx
  3. MRI
20
Q

What is the BIRADS?

A

Breast Imaging Reporting and Data System. Rates on a scale from 0 to 5 – incomplete assessment to high suggestion of malignancy.

21
Q

What is the GOLD standard for initially assessing image detectable lesions in the breast?

A

Needle Biopsy

22
Q

T/F: Most biopsies of the breast require open surgical biopsy

A

False! Only 5-10% should require it.

23
Q

When you have an abnormal biopsy result, what should you do next?

A

Excisional Biopsy – Needle localized breast bx. It goes all the way through to the musculature in the back and then comes back

24
Q

What is the TNM staging?

A

T- Tumor Size
N- Lymph Node
M- Metastasis

25
Q

Staging of Tumor Size

A

1- 5 cm

4- Extends to skin or chest wall

26
Q

Staging of Lymph Nodes

A

0- No lymph node metastases
1- Metastasis to ipsilateral, movable, axillary lymph nodes
2- Metastasis to ipsilateral fixed axillary or IM lymph nodes
3- Metastasis to infraclavicular lymph node or to axillary and IM lymph nodes

27
Q

Staging of Metastasis

A

0- No distant metastasis

1- Distant Metastasis

28
Q

Common metastases sites for breast cancer

A
  1. Lymph Nodes
  2. Lung
  3. Liver
  4. Bone
  5. Brain
29
Q

What are the biomarkers for breast cancer

A
  1. Hormone Receptors (ER/PR = Good)

2. Her2/neu (ERB2) – Epidermal growth factor family = Bad

30
Q

Treatment options for Breast Cancer

A
  1. Surgery
  2. Chemo
  3. Radiation
31
Q

What is the primary treatment for early stage breast cancer?

A

Surgery – Lumpectomy or partial mastectomy, mastectomy, or modified radical mastectomy

32
Q

What are the contraindications for Breast Conservation Therapy?

A
  1. First and second trimester preggo
  2. Multicentricity
  3. Diffuse suspicious microcalcifications
  4. Prior therapeutic RT to breast
  5. Persistent positive margins
  6. Connective Tissue Issues (except RA)
  7. Large Tumor in Small Breast
33
Q

Tell me about Skin, Nipple, Areolar Sparing Mastectomy

A
  • Ideal for early stage breast cancer and/or preventative operations
  • Saving skin facilitates reconstruction
  • Nipple and Areola can be reconstructed in staged procedures.
34
Q

What is the first lymph node of drainage from the breast?

A

Sentinel Lymph Node; Found with radioactive tracer and/or blue dye.

*Allows for histological examination of single node.

35
Q

Challenges with Whole Breast Radiation Therapy

A
  1. Geographic Miss
  2. Collateral Damage
  3. Cosmesis
  4. Delay in starting one or other modality
36
Q

Examples of Collateral Damage from Whole Breast Radiation Therapy

A
  1. Cardiac Ischemia
  2. Lung Cancer
  3. Esophageal Cancer
  4. Contralateral breast cancer
  5. Radiation induced sarcoma
37
Q

Chemotherapeutic Hormone Receptor Modulators

A
  1. Tamoxifen (needs to have a positive receptor)

2. Raloxifen

38
Q

Chemotherapeutic Alternates

A
  1. Steroids
  2. Aromatase Inhibitors (anastrozole) (only Postmenopausal women)
  3. Bilateral oophorectomy
39
Q

Follow up after Breast Cancer Treatment

A
  1. H&P Q 3-6 months for first 5 years, then yearly
  2. Mammogram Q 12 months
  3. Bone density scan if on aromatase inhibitors
  4. Annual GYN exam if on Tamoxifen and uterus present
