Treatment options Flashcards
Masectomy
Total: breast
Radical: breast, lymph nodes, pectoralis maj/min (outdated)
Modified radical: breast, lymph nodes, pectoral fascia
ALND: Level 1/2
Indications: DCIS, stage 1/2/3 BC, BC in more than 1 quadrant, Pagets, Inflamm BC, recurrent BC, carrier of gene mutation.
Lumpectomy
Surgical removal of tumor, lymph nodes, radiation/chemo.
Indications: benign breast lumps, high risk lesion, cancerous lesion
Masectomy types
Total: remove breast tissue including skin, aerola, nipple.
Skin sparing: remove breast tissue, nipple, aerola but NOT skin.
Nipple sparing: removal of ONLY breast tissue, spares nipple/aerola
Prophylactic masectomy
Surgical removal of one or both breasts. Done in women with high risk of BC. Reduces risk by 90%. Still a 5-10% of recurrence rate on same breast, less than 2% recurrence on opposite breast.
EBRT
Burns chest wall killing abnormal & normal cells. commonly used in DCIS, lumpectomy & controls spreading CA. Given daily for 5-6 wks. Will begin after surgery 5 wks/after chemo 3-4 wks.
Brachytherapy (internal)
A catheter is connected to a machine that inserts a high dose rad seed sent to the site. Done 3-5 days twice a day.
IORT
Rad therapy given right after lumpectomy. The mass has been removed by surgeon then on the exposed breast tissue a single high dose of rad will be given where mass was.
Chemo
Stops cancer cell growth & rapidly dividing cells. Used w/ other treatments, surgery, drugs, rad therapy.
Chemo neo adjuvant (before surgery)
Shrinks tumor/conserves tissue.
Chemo adjuvant (after surgery)
Recommended if has spread to lymph nodes, premenopausual women (BC aggressive), advanced/metastatic CA, Her 2 (aggressive)
Endocrine therapy
Breast CA hormone +. Estrogen/progesterone receptors feed CA cells. Tamoxifen common. Works by binding to CA cell, blocking ER/PR from binding.
Aromatose inhibitor
Useful with postmenopausal women, decreases amount of estrogen in body.
Side effects: increase risk of osteoporosis, blood clots & heart issues
Anti Her2
Her 2 are protein receptors that stimulate cell growth. 20-25% in CA.
Treatment:
Herceptin. Will block her 2 overstimulation.
Combo of herceptin/chemo. Will shrink tumor.
Ovarian ablation:
Shuts down ovaries to reduce hormone production. Done on premenopausual women. Can be done through surgery, rad, drugs.
Side effects: early menopause, infertility, hot flashes
TNBC
Tumor that does NOT have any receptors. Chemo will work best, neoadjuvant -> surgery -> adjuvant -> rad. Aggressive/difficult to treat. 10-20% of BC.
