Eligibility criteria:
Inclusion Criteria:

Patients must have histologically or cytologically confirmed Breast Cancer, stage IV, including:

"Breast neoplasms malignant and unspecified (incl nipple)","Breast and nipple neoplasms malignant","Breast cancer stage IV","10006202"
Breast neoplasms malignant and unspecified (incl nipple)","Breast and nipple neoplasms malignant","Breast cancer recurrent","10006198"
"Breast neoplasms malignant and unspecified (incl nipple)","Breast and nipple neoplasms malignant","Inflammatory carcinoma of breast stage IV","10021979"
Patients must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded) as >= 20 mm with conventional techniques or as >= 10 mm with spiral CT scan
Patients must have refractory breast cancer, defined as overt clinical tumor progression on most recent treatment with either hormonal therapy, chemotherapy, and/or trastuzumab therapy; patients with up to 3 prior chemotherapy regimens and with any number of biological (hormonal, trastuzumab) regimens for metastatic breast cancer will be eligible
Life expectancy of greater than 3 months as assessed by the patient's primary oncologist
Absolute neutrophil count > 1,500/mcL
Platelets > 100,000/mcL
Hemoglobin >= 8 g/dL
Prothrombin time < institutional upper limit of normal (ULN)
Total bilirubin =< 1.5 x ULN
AST(SGOT)/ALT(SGPT) =< 2.5 × ULN
Creatinine within normal institutional limits
Urinalysis with < 1+ proteinuria
Troponin T or I within normal institutional limits
LVEF >= 45%, as assessed by echocardiogram or nuclear medicine gated study, within 30 days prior to initiating protocol-based treatment
At present, the potential of AZD2171 for clinically significant drug interactions involving the CYP isozymes is unknown; however, studies of the agent in rats indicated possible suppression of CYP1A that may be of biological significance; eligibility of patients receiving any medications or substances known to affect or with the potential to affect the activity or PK of AZD2171 will be determined following review of their case by the Principal Investigator.
AZD2171 has been shown to terminate fetal development in the rat, as expected for a process dependent on VEGF signaling; for this reason, women of child-bearing potential must have a negative pregnancy test prior to study entry; women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately
No therapeutic anti-coagulation; the use of low dose warfarin (1-2 mg/day), intermittent doses of TPA (2 mg x 1), or heparin flushes to prophylax against central venous catheter-associated clots is acceptable
Ability to understand and the willingness to sign a written informed consent document

Exclusion Criteria:

Patients who have had chemotherapy, radiotherapy, or major surgery within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier
Patients may not be receiving any other investigational agents nor have participated in an investigational trial within the past 30 days
Patients may not have been previously treated with an anti-angiogenesis agent
\Patients may not be receiving any medication that may markedly affect renal function (e.g., vancomycin, amphotericin, pentamidine); these medications will also not be permitted after the start of the study
Patients with known brain metastases should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events; a head CT or MRI must be performed at baseline
History of allergic reactions attributed to compounds of similar chemical or biologic composition to AZD2171
Any contraindications/barrier to oral medication
EKG abnormalities of known clinical significance, such as prolonged QT (mean QTc > 470 msec, with Bazett's correction, in screening electrocardiogram or history of familial long QT syndrome); an EKG is required for study entry
Uncontrolled intercurrent illness including, but not limited to hypertension, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
Pregnant women are excluded from this study because AZD2171 is a VEGF inhibitor with known abortifacient effects; because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with AZD2171, breastfeeding should be discontinued if the mother is treated with AZD2171
HIV-positive patients on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with AZD2171; appropriate studies will be undertaken in patients receiving combination antiretroviral therapy when indicated
Patients at increased risk for compromised LVEF requiring concurrent use of drugs or biologics with proarrythmic potential; these drugs are prohibited during studies with AZD2171 (refer to Appendix J for a listing of these agents)
Patients with a New York Heart Association classification of III or IV are excluded (NOTE: patients classified as class II are eligible if controlled on medication and stable with increased monitoring)
