by CT or MRI
- Patients must have at least one "target lesion" to be used to assess response on this

therapy

carcinoma; all hormonal therapy must be discontinued at least 4 weeks prior to
registration

- Left ventricular ejection fraction (LVEF) >= 50%
- Fasting cholesterol less than or equal to 300 mg/dl; fasting triglycerides less than
or equal to 300 mg/dl
- Prothrombin time (PT) such that international normalized ratio (INR) is less than or
equal to 1.5 x ULN (or an in range INR, usually between 2 and 3, if a patient is on a
stable dose of therapeutic warfarin) and a partial thromboplastin time (PTT) less than
or equal to 1.5 times the upper limit of normal
- The patient must provide study-specific informed consent prior to study entry and, for
patients treated in the United States (U.S.), authorization permitting release of
personal health information
- Diabetic patients (type I or II diabetes mellitus) must have baseline hemoglobin
(Hb)A1c levels NOT higher than 8.5% at study entry

150 mmHG or diastolic pressure < 90 mmHG at study entry
- Note: ULN is institutional or laboratory upper limit of normal

within 28 days of registration; the patient and her sexual partner(s) must agree to
use adequate contraception when sexually active for the duration of the study and for

permanent sterilization methods include hysterectomy, bilateral salpingectomy and
bilateral oophorectomy; a postmenopausal state is defined as no menses for 12 months
