A

Micropapillary

18
Q

Profile of metaplastic breast cancer (2)

A
  • Heterogenous group
  • Usually triple negative
19
Q

Modified Scharff-Bloon-Richardson Grading System

A
  • Well-differentiated / low grade (I/III)
  • Intermediate grade (II/III)
  • Poorly differentiated / high grade (III/III)
20
Q

If e-cadherin positive, what is the type of breast cancer?

21
Q

If e-cadherin is negative, what is the type of breast cancer?

22
Q

Profile of breast cancer that tends to metastasize to brain

A
  • Triple negative
  • Her2+
23
Q

3 other common breast lesions aside from carcinomas

A
  • Fibroepithelial lesions
    • Fibroadenoma
    • Phyllodes tumor
  • Papilloma
24
Q

Most common breast tumor in young women

A

Fibroadenoma

NOTE: Usually appears before 30 and can regress after menopause

25
Gross appearance of fibroadenoma
* Round * Rubbery (can compress it) * Well-circumscribed
26
Risk of cancerous progression of fibroadenoma
None
27
Histological profile of fibroadenoma
Biphasic (stromal and epithelial) NOTE: Carcinoma = epithelial only
28
Histological profile of phyllodes tumor
More pronounced stroma; very cellular (can make a sarcoma)
29
7 prognostic factors of breast cancer
* Axillary lymph node status * Tumor size * Vascular invasion * Grade * Tumor subtype * ER/PR expression * Her2 * Overexpression/amplification
30
3 predictive factors of breast cancer
* ER/PR * HER2 * Oncotype DX (RT-PCR -- 21 GENES, RECURRENCE SCORE) * Predict benefit from chemotherapy and hormonal therapy
31
5 treatments for breast cancer
* Surgery * Radiation therapy * Hormonal therapy * Chemotherapy * Targeted therapy: herceptin, lapatinib
32
4 intrinsic subtypes of breast cancer
* Luminal A (ER+ and/or PR+, HER2-) * Luminal B (ER+ and/or PR+, HER2+) * HER2 (ER-) * Basal-Like (Triple negative, cytokeratin 5/6+ and or/ EGFR+)
33
Most common subtype of breast cancer
Luminal A
34
Prognosis of Luminal A breast cancer subtype
* Less aggressive * Lower histological grade * Good prognosis * Hormone responsive
35
Risk factor for Luminal A breast cancer
Associated with increasing age
36
Which Luminal subtype has a worse outcome?
Luminal B
37
Prognosis of HER2+ (ER-) breast cancer subtype
* Highly aggressive * High grade histology * Outcome improved with HER2
38
2 risk factors for HER2+ (ER-) breast cancer subtype
Risk as young age greater than luminal subtypes African American ethnicity may be factor
39
Prognosis of basal-like breast cancer
Aggressive High-grade histology High mitotic rate
40
Risk factors for basal-like breast cancer
Younger age (\<40) More likely premenopausal African American women
