Breast Cancer Clinical Application Flashcards
(22 cards)
8 Br CA risk factors?
- Age
- Gender
- Nulliparity or late parity
- Early menarche
- Late menopause
- Previous breast cancer
- Family history
- Proliferative changes on biopsy
The Gail Model calculates risk based on: (5)
age age at menarche age at first childbirth family hx proliferative
*If calculated risk > 1.67, consider chemoprevention
ACS Mammo guidelines:
starting at age 40
annually after 40
*Differ for women with genetic mutation or strong family history
ACS Clinical exam guidelines:
every 3 years 20 – 39
annual after 40
*Differ for women with genetic mutation or strong family history
USPSTF Recommendations are against
- routine screening 40 – 49
- teaching routine self exam
(recommends Biennial screening 50 – 74; lecturer was highly critical of this)
Why are MRI’s not favorable breast CA screening tools?
high false (+) rate \$\$\$\$
Why are ultrasounds not favorable breast CA screening tools?
only good with mammogram, not as an isolated screening test
CC (craniocaudal) screening view =
shot from above
MLO (medial lateral oblique) =
shot at 45 degree angle + includes the lateral pectoral muscle
ML (medial lateral) =
shot at 90 degree angle + does not include the lateral pectoral
Which of the Mammogram BIRADS Categories should be referred for biopsy?
4 + 5
suspicious/highly suspicious
What’s the difference between a diagnostic and screening mammogram?
dx: radiologist looks at imaging BEFORE the patient leaves to determine if more imaging needed
Indications for a diagnostic mammo:
- abnormality on physical exam
- abnormality on screening
- history of breast cancer
What are some types of suspicious microcalcifications?
pleomorphic
clustered
linear
increasing in number
What are some types of suspicious masses?
irregular borders
spiculated
increasing in size
In order to do a biopsy of a lesion, it must be:
visible on US
How do you do a biopsy for lesions NOT visible on US?
Stereotactic Biopsy (patient is up on a table over your head..)
What are the indications following biopsy of a lesion?
6 month followup
Xray evaluation of specimen
How does Breast Conservation compare to Mastectomy?
they are equivalent in:
- -Long-term survival
- -Distant disease-free survival
- -Local recurrence (w/ RT)
- -Need for chemo
Contraindications to Breast Conserving Surgery?
- Tumor size (tumor : breast)
- Previous radiation
- Multicentric disease (>1 quadrant)
- Pregnancy
- Persistent positive margins
- Relative if:
collagen vascular disease (e.g. SLE)
multifocal disease
large breasts
Whether or not a patient needs adjuvant therapy depends on:
Tumor size ≥ 1 cm
ER/PR negative ≥ 5 mm
Her 2 positive ≥ 5 mm
Nodes positive
I left off most of the case stuff. She clicked through it, and it seems too complicated for us to really be responsible for.
Maybe if I become a boobie-surgeon I’ll need to learn it in serious depth. But not for today.
