Primary outcomePrimary: Number of Participants Experiencing in Situ Anti-tumor Effect of Tarceva — 8 participants
Summary
RATIONALE: Erlotinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving erlotinib before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.
PURPOSE: This phase II trial is studying how well erlotinib works in treating patients with breast cancer that can be removed by surgery.

Eligibility Criteria
Inclusion Criteria
- Clinical stage I or II (T1 or T2, N0 or N1) invasive mammary carcinoma
- Diagnosis may be made by fine needle aspiration cytology or core biopsy
- A repeat core biopsy is not required for patients who have a paraffin embedded diagnostic core biopsy specimen available for immunohistochemical staining
Exclusion Criteria
- Patients with locally advanced disease who are planning to undergo preoperative neoadjuvant therapy are not eligible*

- Measurable residual tumor at the primary site
- Measurable disease is defined as any mass that can be reproducibly measured by physical examination
- Planning to undergo surgical treatment with either segmental resection or total mastectomy
- Patients with a prior history of contralateral breast cancer are eligible if they have no evidence of recurrence of their initial primary breast cancer
- No locally recurrent breast cancer
- No evidence of distant metastatic disease (i.e., lung, liver, bone, or brain metastases)

- ANC ≥ 1,000/mm^3
- Creatinine ≤ 1.5 times upper limit of normal (ULN)
- Total bilirubin ≤ 1.5 times ULN
- Serum glutamic oxaloacetic transminase (SGOT) and serum glutamic pyruvic transminase (SGPT) ≤ 1.5 times ULN
- Must be at least 18 years old
- Not pregnant or nursing
- Negative pregnancy test
- Fertile patients must use effective contraception
- No serious medical illness that, in the judgement of the treating physician, places the patient at high risk of operative mortality
PRIOR CONCURRENT THERAPY:
- See Disease Characteristics
- No prior chemotherapy for this primary breast cancer
