Breast Cancer Therapeutics Flashcards
what are risk factors for breast cancer
Age
Family history
Radiation
Estrogen Exposure (endogenous)
Alcohol
Nulliparity
Elevated BMI
what are the tumor suppressor genes associated with breast cancer?
BRCA-1 and BRCA-2
what are the two most common invasive cancer spots in breast cancer?
lobes
ducts
what is an invasive carcinoma
invaded beyond the basement membrane of the duct or lobule
what are the non invasive breast cancers
ductal carcinoma in situ
lobular carcinoma in situ
inflammatory
what is the most aggressive form of breast cancer
inflammatory
describe inflammatory breast cancer
aggressive, rapid onset
poor prognosis
onset is days and weeks
orange peel look
how to test for HER2 status
IHC or FISH testing
what is oncotype DX
-genetic test for expression of 21 genes which fives recurrence score
-can determine if cancer will return and if patient will benefit from chemo
what is treatment for a low risk (< 26) for oncotype DX
hormonal therapy only
what is treatment for a high risk (>=26) for oncotype DX
chemo and HRT
will women < 50 w/ score of 16 to 25 benefit from chemo?
yes they will benefit
general treatment strategies for breast cancer stages I, II, IIIA
breast conserving surgery
mastectomy
neoadjuvant chemo
adjuvant chemo
what is the goal of BC stages I, II, IIIA
goal is to cure
what is the goal for breast cancer stages IIIB and IIIC?
goal is to cure
what is the general treatment strategy for breast cancer stages IIIB and IIIC?
neoadjuvant chemo
adjuvant therapy as needed
what is the treatment goal for stage IV breast cancer
palliative
what is the general treatment strategy for breast cancer
chemo
HRT
biologics
immunotherapy
what is the adjuvant therapy plan for a HR+ LN -/+, HER2 - woman with a tumor less than/equal to 0.5mg
consider adjuvant endocrine therapy
what is the adjuvant therapy plan for a HR+ LN -/+, HER2 - woman with a tumor greater than 0.5mg with an oncogene score of less than 26
adjuvant endocrine therapy
what is the adjuvant therapy plan for a HR+ LN -/+, HER2 - woman with a tumor greater than 0.5mg and an oncogene score of greater than or equal to 26
adjuvant chemo followed by endocrine therapy
what is the adjuvant therapy plan for a HR+ LN -/+, HER2 + woman with a tumor less than 0.5mg
consider adjuvant endocrine therapy +/- chemotherapy with HER2 targeted therapy
what is the adjuvant therapy plan for a HR+ LN -/+, HER2 + woman with a tumor greater than 0.5mg
adjuvant chemo with HER 2 targeted therapy followed by endocrine therapy
what is an adjuvant hormonal therapy option in breast cancer
SERMs
LHRH analogs (ovarian suppression)
Aromatase Inhibitors
what is the SERM for breast cancer
Tamoxifen (pre and post meno)
anti-estrogen effect
major toxicity - Hotflashes
