Neoadjuvant
Systemic Therapy |
|
Oncologists: The following patients
with 2.8 centimeter, ER-positive, HER2- negative breast
cancers desire breast-conserving surgery; however, their
breasts are too small to allow a good cosmetic outcome
with lumpectomy at the present time. Which neoadjuvant
regimen would you use?
(See next page for choice of hormonal
therapy) |
|
A majority of oncologists would use neoadjuvant systemic therapy
of some kind in these patients. Note the frequent use (40-75%) of
neoadjuvant chemotherapy alone or in combination with hormonal therapy,
re g a rdless of the patients age. The most commonly utilized
neoadjuvant chemotherapy regimen is AC. Elderly patients are the
only group in whom endocrine therapy alone is used to a significant
extent.

Neoadjuvant
Endocrine Therapy |
|
Oncologists: Of those using
preoperative endocrine therapy, which therapy would
you use in the following women with 2.8 cm, ER-positive,
HER2- negative breast cancers?
|
|
The inappropriate use of aromatase inhibitors in premenopausal
women is most striking. These agents are indicated for postmenopausal
women only. Also of note in postmenopausal women, aromatase inhibitors
are used more often than tamoxifen, reflecting recently reported
neoadjuvant studies indicating greater efficacy. Of the a romatase
inhibitors, anastrozole is more widely utilized among oncologists
than other agents.

Neoadjuvant
Chemotherapy and Trastuzumab |
|
Oncologists: Would you utilize
neoadjuvant chemotherapy and/or trastuzumab in the following
women with ER-negative, HER2-positive breast cancers?
|
|
There are many ongoing randomized clinical trials of neoadjuvant
chemotherapy with and without trastuzumab. A significant number
of oncologists (35-65%) state that they would use trastuzumab in
the neoadjuvant setting at the present time in a non protocol setting.
Of the physicians using neoadjuvant trastuzumab and chemotherapy,
30-50% would use a cytotoxic regimen containing an anthracycline,
despite concerns of cardiotoxicity with these agents in combination.
