Alternate Title

Combination Chemotherapy Followed by Radiation Therapy With or Without Surgery in Treating Women With Locally Advanced or Inflammatory Breast Cancer

Basic Trial Information

Phase Type Status Age Sponsor Protocol IDs Phase III Treatment Closed 70 and under Other EORTC-10994 ACCOG-EORTC-10994, SAKK-EORTC-10994, SBGC-EORTC-10994, BIG-1-00, NCT00017095

Objectives

1. Compare neoadjuvant fluorouracil, epirubicin, and cyclophosphamide vs docetaxel and epirubicin followed by radiotherapy and surgery in women with locally advanced, inflammatory, or large operable breast cancer.
2. Compare the progression-free survival of patients treated with these regimens.
3. Compare the distant metastasis-free survival and survival of patients treated with these regimens.
4. Compare the clinical and pathological responses to these regimens in these patients.
5. Compare the toxicity of these regimens in these patients.

Outline

This is a randomized, multicenter study. Patients are stratified according to stage of disease (large T2-3 vs locally advanced or inflammatory), p53 status (negative vs positive vs unknown), and participating center. Patients are randomized to 1 of 2 chemotherapy treatment arms.

• Arm I: Patients receive 1 of 3 chemotherapy regimens comprising fluorouracil, epirubicin, and cyclophosphamide (FEC) (according to participating institution).
  • FEC 100: Patients receive fluorouracil IV over 15 minutes, epirubicin IV over 1 hour, and cyclophosphamide IV over 1 hour on day 1. Treatment repeats every 3 weeks for 6 courses in the absence of disease progression or unacceptable toxicity.
  • Canadian FEC: Patients receive oral cyclophosphamide on days 1-14 and epirubicin IV and fluorouracil IV on days 1 and 8. If oral medications are not tolerated, patients may switch to cyclophosphamide IV on days 1 and 8. Treatment repeats every 4 weeks for 6 courses in the absence of disease progression or unacceptable toxicity.
  • Tailored FEC: Patients receive fluorouracil IV over 15 minutes, epirubicin IV over 1 hour, and cyclophosphamide IV over 1-2 hours on day 1. Patients also receive filgrastim (G-CSF) subcutaneously on days 2-15 or until blood counts recover. Treatment repeats every 3 weeks for 6 courses in the absence of disease progression or unacceptable toxicity.



• Arm II: Patients receive docetaxel IV over 1 hour on days 1, 22, and 43 followed by epirubicin IV over 15 minutes and docetaxel IV over 1 hour on days 64, 85, and 106 in the absence of disease progression or unacceptable toxicity.

Following chemotherapy, patients may undergo loco-regional therapy comprising radiotherapy with or without breast conservation surgery or mastectomy. Patients with estrogen- and/or progesterone-receptor-positive disease also receive tamoxifen or an aromatase inhibitor for 5 years.

Patients are followed every 3 months for 1 year, every 4 months for 1.5 years, and then every 6 months thereafter.
