What are 2 factors that are most prognostic for breast cancer?
tumor size and axillary lymph node status
T/F: If mammogram is normal, you don’t need to biopsy a breast mass
False. You need to do a biopsy
1) How do you treat DCIS?
2) What if it is estrogen-positive DCIS?
1) wide excision (lumpectomy) with breast radiation
2) tamoxifen decreases risk of local recurrence but not survival
Which is better for invasive breast cancer treatment: mastectomy vs lumpectomy with both followed by radiation?
both are the same
For breast tumors that involve the skin, chest wall, or more than one quadrant of the breast, what is the recommended treatment?
mastectomy
For inflammatory breast cancer, what is the best treatment?
neoadjuvant chemo then mastectomy then radiation
What is a contraindication to breast radiation therapy?
previous irradiation
When would a bilateral mastectomy be recommended?
familial breast cancer syndromes
When is axillary lymph node dissection performed? (2)
stentinel lymphe node biopsy is positive or axillary lymph nodes are clinically involved
For patients with breast tumors >5cm, positive surgical margins, skin or chest wall involvement, inflammatory breast cancer, and positive axillary nodes…what is the recommended treatment?
mastectomy followed by chest wall radiation
What staging is adjuvant systemic therapy used in breast cancer?
stages I to III (not metastatic and is curable)
When do you use tamoxifen as adjuvant therapy?
premenopausal women x 10 years. If they become postmenopausal after taking 5 years of tamoxifen, then they benefit from taking aromatase inhibitor for 5 years
For patients on aromatase inhibitors (anastrozole, letrozole, exemestane), how often do you do DEXAs and bisphosphonate therapy?
q1-2 years and treat if T scores
What is indicated in hormone receptor-negative tumors, HER2-positie tuors, high grad tumors, extensive lymphovascular invasion and positive lymph nodes?
adjuvant chemotherapy
T/F: Patients with high risk recurrence scores will benefit when adjuvant chemotherapy is given followed by antiestrogen therapy
True
What can be given as adjuvant therapy with HER2-positive breast cancer? What prework up do you need to do?
trastuzumab; check LV function
If patients are hormone receptor negative or fail antiestrogen therapy, what can be used?
single agent chemotherapy
How do you treat lytic bone metastases in breast cancer?
bisphosphonate and denosumab
If a premenapausal woman cannot take tamoxifen, what do you need to do?
ovarian ablation or suppression
T/F: pregnancy after breast cancer does not increase the risk of recurrence
true
T/F: You need to biopsy new metastatic lesions
True–primary tumor and metastatic tumor estrogen receptor and HER2 status can differ
What are the side effects of 1) aromatase inhibitors? 2) tamoxifen 3) anthracyclines (doxorubicin, epirubicin) 4 trastuzumab 5) bisphosphonates 6) denosumab
1) arthralgia, bone pain, osteoporosis, hyperlipidemia
2) endometrial cancer, VTE disease
3) cardiomyopathy, acute leukemia
4) cardiomyopathy especialy with anthracycline
5) osteonecrosis of jaw especially with dental disease
6) hypocalcemia and osteonecrosis of jaw especially with dental disease
What are the criteria for annual low dose screening CT scan for lung cancer?
smoking for 20 pack years, quit within 15 years
ages: 50-80yo
Where is the best place to biopsy a lung mass?
peripheral lymph node of mediastinal node
