Surgery - Breast Flashcards
US for breast best to detect masses of what size?
> 1cm in diameter
Acute mastitis
- causes
- description
- tx
Usually due to S. aureus. It is a cellulitis (vs breast abscess needing drainage)
Need to r/o breast cancer!
Dicloxacillin
Cephalosporins
Cont breast feeding as can dec progression of mastitis to breast abscess
Mammo guidelines
- Should start at age 40
- DO NOT DO before 20 (breast too dense) or lactation (all is milk)
Fibroadenoma
- description
- management
Young women (< 35 yo)
Firm, mobile, rubbery mass
Increase size/tenderness with menstruation
FNA
Sonogram
OPTIONAL removal
Giant juvenile fibroadenomas
- description
- management
Young adults
Rapid growth
YES remove
To avoid deformity and distortion of breast
Cystosarcoma phyllodes
- description
- management
30-50 yo
LARGE bulky mass that is mobile and arises from lobular tissue
Most benign, but can turn malignant
Core or incisional bx
YES remove
Fibrocystic disease
- description
- management
30s-40s Tender + grow w/ menstrual cycle Usually not increase risk of carcionma Diff histo types: - fibrosis - cystic - sclerosing adenosis (microcalcificatiosn on mammo) - epithelial hyperplasia
Mammo if no dominant or persistent mass
If persistent mass –> aspiration (not FNA)
If aspiration doesn’t disappear –> formal bx needed
Intraductal papilloma
- description
- management
Young women
Grows in lactiferous ducts
No increased cancer risk
Bloody nipple discharge
Mammogram to ID other lesions – will not show papilloma b/c too tiny
Galactogram (dx and for surgery resection)
Breast abscess
- description
- management
In lactating women
I & D
Bx of abscess wall
Treatment for breast cancer during pregnancy
No radiation
No chemo in 1st trimester
OK to keep pregnancy
DCIS
- description
- management
Can’t mets
Usually looks like microcalcifications on mammo
comedo has highest malignant potential
Diffuse lesions: Total simple mastectomy + Sentinel node bx
1 lesion: Lumpectomy + radiation
Breast cancer – resectable
- what do you do?
How about if not resectable?
Resectable:
Lumpectomy + axillary sampling + postop rad
Modified radical mastectomy + axillary sampling (sentinel lymph nodes)
Not resectable:
Chemo
Breast Cancer mets
- where does it go?
- dx?
- Tx?
Brain
<3 vertebral pedicles
Tx breast cancer in premenopausal? postmen?
Pre = tamoxifen
Post = anastrozole
Breast Cancer stage I
Tumor ≤ 2cm in diam
(-) mets
(-) nodes
Breast Cancer stage IIA
Tumor ≤ 2cm in diam + mobile axillary nodes
OR
Tumor 2-5 cm in diam, (-) nodes
Breast Cancer stage IIB
Tumor 2-5cm in diam + mobile axillary nodes
OR
Tumor > 5 cm, (-) nodes
Breast Cancer stage IIIA
Tumor > 5cm + mobile axillary nodes
OR
Any size + fixed axillary nodes, (-) mets
Breast Cancer stage IIIB
Peau d’orange OR Chest wall invasion/fixation OR Inflammatory cancer OR Breast skin ulceration OR Breast skin satellite mets OR Any tumor + ipsilateral internal mammary lymph nodes
Breast Cancer stage IIIC
Any size tumor, (-) mets
+ supraclavicular, infraclavicular, or internal mammary lymph nodes
Breast Cancer stage IV
Distant mets (including ipsilateral supraclavicular nodes) - Loves: lymph nodes, lung/pleura, liver, bones, brain
Metastatic breast cancer to bone - test to dx?
MRI
Mammo results w/ strong correlation with breast cancer
(1) breast calcifications that are
(a) smaller than 2 mm,
(b) punctate, microlinear, or branching,
(c) clustered along ducts or concentrated in clusters >5 calcifications per square centimeter;
(2) stellate-shaped lesions;
(3) masses with ill-defined borders or nodular contours;
(4) solitary dominant masses that are significantly larger than any other mass in either breast; and
(5) areas of increased noneffacing tissue density or distorted breast architecture.
