To determine whether economically disadvantaged urban women with locally advanced breast cancer (American Joint Committee on Cancer stages IIB to IIIB) have rates of response to sequential neoadjuvant chemotherapy and radiation, breast salvage rates, overall survival rates, and disease-free survival rates comparable with those previously reported in other socioeconomic groups and to compare these variables in different ethnic groups within the study population.
Prospective, nonrandomized, case series.
Urban county hospital.
Thirty-seven women with locally advanced breast cancer who came to the breast clinic at Cook County Hospital, Chicago, Ill, during a 3-year interval.
Sequential chemoradiation followed by surgery in selected patients.
Main Outcome Measures:
Comparison of clinical response rates, disease-free survival rates, and breast salvage rates between different ethnic groups in the study population.
In the entire group, the overall response rate to neoadjuvant chemotherapy was 73%, with a complete response rate of 32%. Twenty-five percent of patients whose tumors responded incompletely to chemotherapy had a complete response after subsequent radiation. With a mean follow-up of 18.7 months, 65% of patients had no evidence of disease, and breast salvage without evidence of recurrent disease was achieved in 38% of patients. No differences in overall response rates, breast salvage rates, or early disease-free survival rates were observed within different ethnic groups in the study population, and these results are generally comparable with previously reported results in other socioeconomic groups.
These results do not show significant differences in responses to sequential chemotherapy and irradiation, in breast salvage rates, or in survival between different ethnic groups in this study population.(Arch Surg. 1996;131:424-428)
