RATIONALE: Erlotinib may stop the growth of tumor cells by blocking the enzymes necessary for tumor cell growth. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining erlotinib with docetaxel may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combining erlotinib with docetaxel in treating patients who have stage IV or recurrent breast cancer.
OBJECTIVES: * Determine the antitumor effects of erlotinib and docetaxel, in terms of objective response, stabilization of disease, and progression-free survival, in patients with stage IV or recurrent breast cancer. * Determine time to tumor progression in patients treated with this regimen. * Compare time to tumor progression in patients who achieve disease stabilization or response after treatment with this regimen and continue to receive erlotinib versus patients who do not receive additional erlotinib. OUTLINE: Patients receive docetaxel IV over 1 hour once weekly for 3 weeks and oral erlotinib once daily beginning on day 1. Treatment repeats every 4 weeks for a minimum of 6 courses in the absence of unacceptable toxicity or disease progression. Patients achieving maximal tumor response or stabilization of disease after 6 courses may continue to receive erlotinib alone until disease progression. Patients are followed for survival. PROJECTED ACCRUAL: A total of 30 patients will be accrued for this study within 12-14 months.

Docetaxel IV infusion weekly for 3 weeks with a one-week break. One cycle is 4 weeks (28 days). Patients' actual weight will be used to calculate dose.
OSI-774 will be taken 1 hour before or 2 hours after meals. Cycle 1 will be administered at dose level -1.If no grade 3 or 4 toxicity occurs during cycle 1, then the patient may proceed to be treated at dose level 0 for the remaining chemotherapy cycles.

Disease Response (Tumor Measurements)Per RECIST Criteria v. 2000
Response and progression will be evaluated in this study using the criteria by the Response Evaluation Criteria in Solid Tumors (RECIST) Committee. Changes in only the largest diameter (unidimensional measurement) of the tumor lesions are used in the RECIST criteria. Partial Response: At least a 30% decrease in the sum of the longest diameter (LD) of target lesions. Progressive Disease: At least a 20% increase in the sum of the LD of target lesions. Stable Disease: Neither sufficient shrinkage nor sufficient increase.
Time frame: after 6 course (6 months) of combination therapy
Progression Free Survival(PFS)
Progression free survival was defined as time from the start of treatment to the date of cancer progression, or death, and censored at the date of last follow-up for those without disease progression and still alive. Stable disease is measured from the start of the treatment until progression, taking as reference the smallest measurements recorded since the treatment started. Progressive Disease (PD): At least a 20% increase in the sum of the LD of target lesions. Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD.
Time frame: 3 years
Overall Survival as of 2008
Overall survival (OS) was defined as time from the start of treatment to death, and censored at the time of last assessment for survivors.
Time frame: 5 yrs
