Breast Flashcards
Palpable Breast Mass HPI?
HPI- cyclic pain, nipple dc, skin color changes, personal hx, family hx of breast or ovarian, reproductive hx, hormonal or HRT, trauma, ASK Bone pain, XRT
Palpable Breast Mass PE?
- PE- bilateral breast, size, nipple dc, erythema, adenopathy (ax, supraclavicular nodes, cervical), Palpate the liver
Palpable Breast Mass Ddx?
- DDx- Cyst, fibroadenoma, fat necrosis, ca, lipoma, fibrocystic dz
Palpable Breast Mass Gail, Triple test, needle bx doesn’t match up?
- Note-
- GAIL- 5 yr and lifetime risk could benefit from chemoprevention 50% risk prevention
- Triple Test =US/MMG/CNB is std, 100% accuracy dx benign lesions
- Be careful when the needle biopsy does not match clinical or MMG-need to still excise
BIRADS?
BIRADS- 0- indeterminate 1-Normal (repeat 1yr) 2-Benign (no bx) 3-likely benign (f/u MMG 6mo, follow for 2 yrs then downgrade to 2) 4 - suspicious (needs a bx 40% malignant) 5- Malignant (5% will be normal) 6 - known
Palpable Breast Mass imaging?
- Imaging
- US-for any palpable mass (not good for screening but diagnostic), cyst vs solid
- MMG-Still need, and bilateral
Palpable Breast Mass CNB?
- CNB (clips, receptor status) ((If Palpable)) - at least 14 G multiple passes 10-14 typically all removed (no need for imaging if palpable), better than a surgical bx just as accurate, cheaper, less cosmetic effects, leave clips
Palpable Breast Mass CNB indeterminate ?
CNB results indeterminate, LCIS, atypical hyperplasia, RADIAL scar, papilloma —>excision (30% have DCIS or cancer) and send of ER/PR receptors can be done under local or general
Palpable Breast Mass fibroadenoma?
- Fibroadenoma -most can be left alone AFTER confirmation of core biopsy. May excise if growing, painful, or large >3cm
- Fibroadenoma, Fat Necrosis, Sclerosis (can mimic BCA clinically and path) require local excision and f/u
- prepubescent fibroadenoma >3 cm
Palpable Breast Mass that is a cyst?
Cyst (simple) - clear fluid if collapses f/u in 6mo after FNA aspiration and repeat unto 3 times, if solid component- bx solid component, Bloody fluid send to path
Palpable Breast Mass that is fibrocystic dz?
- Fibrocystic dz - need to r/o cancer or solid mass, Mondors dz, costochondritis and pregnancy once dx-
- 1st decrease caffeine, fat intake, better support, take NSAIDs for pain 2nd primrose oil (prolactin inhibitor), danazol, bromocriptine, tamoxifen (thought increase risk of endometrial cancer-
- f/u 6mo, SBE,CBE, annual MMG
- last resort is mastectomy segmental or total
- 1st decrease caffeine, fat intake, better support, take NSAIDs for pain 2nd primrose oil (prolactin inhibitor), danazol, bromocriptine, tamoxifen (thought increase risk of endometrial cancer-
Palpable Breast Mass thats an abscess?
- Abscess- I and D. may try aspirate with abx c staph coverage
Palpable Breast Mass phyllodes tumor?
- Phylloides tumor (90% benign) no LN- 1-2 cm margins (unless clinically malignant and invading surrounding tissue (20% at which time mastectomy and no LND), CXR, and chemo only if >5cm doxorubicin and ifosfamide
Palpable Breast Mass plasma cell mastitis? Granulomatous mastitis? lactation mastitis? Non lactation mastitis?
- Plasma cell mastitis, duct ectasia and subareolar chronic abscess require I&D, ABX, Subareolar Excision
- Granulomatous mastitis - steroids no surgery
- lactation mastitis - usually staph- tx increase breast pump (dispose) and ABX and if abcess perc drain it
- Non lactation mastitis- usually anaerobe - drainage plus abx
Palpable Breast Mass c palpable LN?
- If palpable LN then need FNA for staging (can help avoid SLNB if + ) - Note
- Can consider neoadj therapy for larger tumors for BCT consideration 80% effective in conv mastectomy —> BCT
Palpable Breast Mass c SLNB steps?
- SLNB
- should be consider with node neg invasive breast cancer and woman undergoing mastectomy for DCIS
- micromets =10% of the hottest node or suspicious palpated LN
- if more than 5 LN and the hottest was removed than stop at five
- if failed mapping then ALND
- Methylene blue can cause anaphylaxis, skin necrosis
Palpable Breast Mass post mastectomy ? and follow up?
- Oncotype- assessed postop for postmen ER positive cases c borderline tumor characteristics assess the benefit of chemo
- triple neg can benefit from chemo
- post mastectomy XRT improve survival and decreases survival in pts c >4 mets LN, >5 cm
- 5000 rads in divided doses
- BCT postop
- 20 yo SBE monthly, CBE q 3yrs
- 40 yo SBE monthly, CBE annually, MMG annually until 70 yrs
- BRCA 25 yrs MMG and consider alt MRI
Suspicious Mammography Abnormality if path dx doesnt match up?
- if path dx doesn’t account for other findings then repeat or do an excisional bx
Suspicious Mammography Abnormality relative CI to BCT?
- BCT must have postop XRT to match the local recurrence rates as a mastectomy
- relative CI to BCT >5cm, large tumor to breast ratio, pregnancy; absolute is T4 (Inflammatory), multi centric, collagen vascular, previous XRT, central subareolar location, breast too small
Suspicious Mammography Abnormality surgical approach?
- surgical approach - Langer lines, periareolar incision (centrally located), if lower half then radial incision
Suspicious Mammography Abnormality mastectomy borders?
- mastectomy borders
- elliptical incision including NAC, bx site and skin over lesion
- develop superior and inferior flap
- Clavicle, lateral border sternum, latissimus dorsi, inframammary fold
- remove all breast tissue, nipple areolar complex and fascia overlying the pec major
- +/- immediate reconstruction - PRS surgeron, tissue expanders, TRAM
- leave drains
Suspicious Mammography Abnormality c axillary dissection?
- Axillary dissection
- en bloc resection level 1/2 LN
- borders- Posteriorly -subscapularis, latissimus dorsi, Medially- chest and serratus anterior, superiorly- axillary vein laterally -Skin
- avoid injury over skeletonize axillary vein, thoracodorsal nerve, long thoracic nerve
DCIS (stage 0) w/u?
- Hx, Dx, RF, Triple test
DCIS (stage 0) what to ask for on imaging?
- usually pleomorphic changes on MMG
- questions to ask path
- How large is it the tumor, multifocal (mastectomy and SLNB because you won’t be able to do one after) or unifocal
- comedo necrosis in the specimen
- How well differentiated (high grade is worst), grade
- ER/PR receptor status
DCIS (stage 0) what if stereotactic bx can’t be done?
- Need tissue dx
- if stererotactic biopsy can’t be done then wireloc bx
DCIS (stage 0) surgery?
- Surgery - BCT vs Simple (total) mastectomy + SLNB (cuz you won’t have another chance and you may find invasive cancer in the specimen)
DCIS (stage 0) BCT CI?
- Contraindications
- Large size, small breast
- previous radiation
- T4 lesions
- central subareolar mass
DCIS (stage 0) c SLNB???
- SLNB can be considered for high grade lesions (controversial) >4cm comedonecrosis, microinvasion. its a must for invasive cancer, o/w no need
- wire loc if needed, check imaging
- create gross 1 cm margins, amputate and orient specimen (permanent) and check X-ray to verify clip and wire
- palpate for any residual disease
- leave clips for whole breast radiation
DCIS (stage 0) c XRT??
- XRT is mandatory
DCIS (stage 0) notes?
- Mastectomy (risk reduction in recurrence but no survival benefit to a BCT)
- Optimal DCIS margin unknown, but a width of 1 mm or more is associated with decreased chance of recurrence
- Stage is upgraded from 0 if micro invasion or occult invasive dz and treat like invasive disease
- Hormone therapy for ER,PR, HER
- Whole breast radiation
- Std follow up CBE and MMG 6mo for 2 years and annual
- Isolated tumor cells in LN- considered node negative, may have gotten there from biopsy manipulation rather than mets
LCIS (detected on bx as usually as an incidental finding)
- High risk path detected incidental finding on CNB (LCIS, atypical hyperplasia) indicates the need for f/u dx surgical wire localization bx which will reveal coexisting cancer 15% of the time so need to do something
LCIS high risk path?
- High risk path detected incidental finding on CNB (LCIS, atypical hyperplasia) indicates the need for f/u dx surgical wire localization bx which will reveal coexisting cancer 15% of the time so need to do something
LCIS margins?
- when detected incidentally margins free aren’t needed
LCIS marker?
- Marker for increase lifetime risk of cancer (1% per year)
LCIS options?
- 3 options after you confirm its just LCIS after your resection
- 1st- close observation / surveillance alone (annual or biannual CBE, annual MMG, possible annual MRI)
- 2nd - chemoprevention tamoxifen pre or raloxifene for post
- 3rd- bilateral Px mastectomy (No axillary staging) -high risk
LCIS with tamoxifen side effect?
- tamoxifen
- avoid getting pregnancy
- nights sweats, hot flashes, DVT, uterine problems, decreased libido
Advanced Breast Cancer w/u?

- T
Advanced Breast Cancer BRCA testing?
- BRCA testing-
- first degree dx BCA
Advanced Breast Cancer risk and benefits BCS vs MRM?
- Discuss risk and benefits
- BCS pros-
- preserve breast, smaller operation, cons-increased recurrence and risk of positive margins requiring more surgery
- MRM-
- decreased recurrence, only one operation unless recon cons-removal of breast, need recon
Advanced Breast Cancer neo adjuvant tx?
- neoadj- no diff in seroma rates, wound infxn, delayed wound healing
Advanced Breast Cancer SLNB vs Mastectomy?
- Mastectomy should try SLNB however after neoadj therapy slight increase in false-negative rates
- if invasion into pec muscle need to resect with specimen
- leave drains
Advanced Breast Cancer when chemo?
- chemo if >1 cm
Advanced Breast Cancer when XRT?
- radiation if 4 or more LN, tumor >5cm
