Neoadjuvant Epirubicin, Cyclophosphamide, and Paclitaxel With or Without Gemcitabine in Treating Women Who Are Undergoing Surgery for Early Breast Cancer
Summary
RATIONALE: Drugs used in chemotherapy, such as epirubicin, cyclophosphamide, paclitaxel, and gemcitabine use different ways to stop tumor cells from dividing so they stop growing or die. Giving combination chemotherapy before surgery may shrink the tumor so that it can be removed during surgery. It is not yet known which combination chemotherapy regimen is more effective in treating early breast cancer. PURPOSE: This randomized phase III trial is studying different regimens of combination chemotherapy to compare how well they work in treating women who are undergoing surgery for early invasive breast cancer.

paper Addition of gemcitabine did not increase pCR PMID 24360787 ↗
paper 70 (17%, 95% CI 14-21) of 404 patients in the epirubicin and cyclophosphamide then paclitaxel group achieved pCR compared with 71 (17%, 14-21) of 408 patients who received additional gemcitabine (p=0·98). PMID 24360787 ↗
paper 82 (20%, 95% CI 16-24) of 406 patients who received paclitaxel with or without gemcitabine followed by epirubicin and cyclophosphamide achieved pCR compared with 59 (15%, 11-18) of 406 patients PMID 24360787 ↗
paper achieved pCR compared with 59 (15%, 11-18) of 406 patients who received epirubicin and cyclophosphamide first (p=0·03). PMID 24360787 ↗
