POST-PROTOCOL ADJUVANT THERAPY (at physician's discretion - see protocol for recommendations)

Eligibility

• Invasive breast cancer, dxd by core needle or incisional bx (excisional bx not permitted).

• Hormone-receptor poor (both ER & PgR negative or staining present in <10% of invasive cells by IHC).

• HER2-negative (IHC 0-1+ or FISH ratio [HER2 gene copy/chromosome 17] of <2.0 if IHC 2+).

• Resectable, clinical Stg II-IIIA (T2, N0 - T3, N0 or T1-3, N1-2a).  No T4, N2b-3, or M1 disease.  Staging to r/o mets is recommended for Stg III pts.  Multicentric or bilat disease is allowed if target lesion meets eligibility criteria.

• Must undergo pre-tx research bx.

• No prior chemo, hormone therapy, or RT w/therapeutic intent for this cancer.

• Target lesion >1cm, clinically or radiographically.  Palpable or radiographically measurable axillary adenopathy will be recorded, but will not serve as meas disease for prim endpoint.  No axillary disease only (no identifiable tumor in breast that is >1cm on PE or radiographic study).

• No significant hx of bleeding w/i 6 mos pre-regist; no serious or non-healing wound, skin ulcer, or bone fx; no abdominal fistula, GI perforation, or intra-abdominal abscess w/i past 6 mos; no major surgical procedure w/i 28 days pre-randomiz; & no anticipated need for major surgery during study.

• No baseline neuropathy >Grade 2.

• Women or men age >18.

• Zubrod 0-1.

• No pregnant or nursing women.  Women of reproductive potential must have negative pregnancy test at baseline & agree to use effective contraception during study tx.

• No CHF, MI, or unstable angina pectoris; arterial thrombotic event, stroke, or TIA w/i past 12 mos; uncontrolled HTN (systolic >160 or diastolic >90); uncontrolled or symptomatic arrhythmia; or >Grade 2 perip vascular disease.

• Pre-tx MUGA or echo w/LVEF > institutional LLN.

• Granulocytes >1000/mcl; platelets >100,000/mcl; total bili <1.5x ULN; calc or meas CrCl >30ml/min; urine protein <1+ or UPC ratio <1*; serum SGPT <2.5x ULN; Serum ßHCG negative (if applicable); PT/INR <1.5x ULN**.

  *   If urine protein on UA is 1+, pt must have either urine protein:creat ratio <1 or 24-hr urine protein <1gm/24 hrs.

  ** If pt is on therapeutic doses of warfarin, must have INR <3 on stable dose of warfarin, no active bleeding, & no path condition associated w/high risk of bleeding.

• PRE-STUDY REQUIREMENTS:

  Within 16 days pre-regist:  All bloodwork; baseline H&P

  Within 28 days pre-regist:  Mammogram, US, or breast MRI (if used for tumor msmt); serum pregnancy test (if applicable)
