Low Dose Chemotherapy With Aspirin in Patients With Breast Cancer After Neoadjuvant Chemotherapy

Summary

Patients with stage II-III breast cancer who do not achieve a pathologic complete response to neoadjuvant chemotherapy at the time of surgery will be treated with oral low dose continuous cyclophosphamide and methotrexate (CM) in combination with aspirin following surgery and radiotherapy. The primary endpoint is to assess toxicity and safety with secondary endpoints of cytokine correlates and relapse free survival (RFS) at 2 years. The investigators design tests the null hypothesis (H0) that the true primary toxicity event rate will be 5% or less, against an alternative hypothesis (HA) event rate of 25% or more.
