Purpose: Patients with metastatic breast cancer (MBC) refractory to standard therapy have a poor prognosis. We assessed prognostic factors and clinical outcomes for patients with MBC referred to a phase I clinic focused primarily on targeted agents. Patients and Methods: We reviewed the medical records of sequential patients with MBC who presented to our phase I clinic between September 2004 and May 2008 to assess baseline patient characteristics, overall survival (OS), and clinical benefit. Results: A total of 92 patients were identified, with a median age of 53 years (range, 28-83 years). The median number of previous therapies was 5 (range, 1-16 therapies). Of 92 patients, 78 were eligible for and offered ≥ 1 phase I clinical trial. With a median follow-up of 7.4 months, the median OS was 6.7 months (95% CI, 5.2-9.7). In multivariate analysis, independent factors predicting shorter survival were ≥ 10 previous treatments (vs. < 10 previous treatments; hazard ratio [HR], 3.27; 95% CI, 1.37-7.81; P = .008), Eastern Cooperative Oncology Group (ECOG) performance status (PS) 2/3 (vs. 0/1; HR, 2.92; 95% CI, 1.28-6.66; P = .01), and albumin level < 3.5 g/dL (vs. > 3.5 g/dL; HR, 2.88; 95% CI, 1.41-5.89; P = .004). Conclusion: Patients with locally advanced or metastatic breast cancer referred for our phase I studies had a median survival of 6.7 months. Heavily pretreated disease, poor ECOG PS, and/or low albumin levels were associated with significantly shorter survival in a multivariate analysis.
