Trial of Four Schedules of Adjuvant Chemotherapy for Breast Cancer

Name of the Trial
Phase III Randomized Study of Four Schedules of Adjuvant Doxorubicin, Cyclophosphamide, and Paclitaxel in Patients with Node-Positive or High-Risk Node-Negative Breast Cancer (SWOG-S0221). See the protocol summary at http://cancer.gov/clinicaltrials/SWOG-S0221.

Why Is This Trial Important?
Different chemotherapy drugs may affect tumors in different ways. Combining more than one drug and giving them after surgery may be effective in killing any tumor cells not removed surgically. It is important, however, to determine which combination of drugs - and the schedule for administering them - produces the best results while causing the fewest side effects. For example, some drugs may provide additional benefits, such as helping to block blood flow to tumors (a process called antiangiogenesis), and be more tolerable if administered more frequently but in lower doses.

This trial compares the effectiveness of four different treatment schedules using the drugs doxorubicin, cyclophosphamide, and paclitaxel in treating patients who have undergone surgery for stage I, II, or III breast cancer. "Preclinical studies have suggested that a 'metronomic' chemotherapy regimen - the administration of moderate doses more frequently - may optimize the antiangiogenic effects of chemotherapies," said Dr. Budd. "Furthermore, this type of regimen may serve as a ready platform upon which to add future antiangiogenic agents as they become available."

Who Can Join This Trial?
This trial seeks to enroll 4,500 women and men aged 18 and older who have high-risk stage I-III invasive breast cancer and have had their tumors surgically removed. See the full list of eligibility criteria for this trial at http://cancer.gov/clinicaltrials/SWOG-S0221.
