Brief Summary: The purpose of this study is to evaluate whether trastuzumab and letrozole are effective and safe in the preoperative treatment for postmenopausal patients with hormone receptor-positive and HER2-positive breast cancer.
Detailed Description: Eligibility criteria

* Ages Eligible for Study: ≥ 20 years
* Invasive cancer (clinical stage IB-IIIB)
* Measurable tumor larger than 1cm
* ECOG status 0 or 1
* Postmenopausal women

* Age ≥55 years and amenorrhea
* Age \<55 years and amenorrhea for ≥12 months with FSH \>30 mIU/ml
* HER2 positive tumor

* 3 positive on IHC
* 2 positive on IHC with HER2 gene amplification on FISH or SISH using a single-probe or dual-probe
* Estrogen receptor positive tumor

* Positive ER expression with Allred score more than PS3/TS8 or modified Allred score more than PS4/TS7
* Eligible cardiac function

* Normal heard evaluated by ECG

* Consider clinically non-significant arrythmia and ischemic change as normal
* LVEF ≥ 55% measured by ECHO or MUGA scan

Outcome measures

* Primary End-point

* The rate of pathologic complete response (pCR)

* No residual invasive cancer in breast
* Secondary End-point

* Clinical Response Rate
* Safety profiles for the preoperative use of concurrent trastuzumab and letrozole
* The rate of breast conservative surgery
* Total pathologic complete response (tpCR)

* No residual invasive cancer in breast and ipsilateral axilla
* Analysis of biomarkers based on baseline specimen and residual tumor
* Ki67 expression
* cDNA microarray: gene expression profiling
* Association between clinical response rate and circulating tumor cells (CTCs)

* CTCs are measured by CytoGen (SEOUL, KOREA)"
