The purpose of this study was to determine temporal trends in breast-conserving surgery in California from 1988 through 1995. Methods. Logistic regression was used to analyze date on 104 466 cases of early-stage breast cancer reported to the California Cancer Registry. Results. A monotonically increasing trend in breast-conserving surgery was detected after adjustmen tfor age, race/ethnicity, stage at diagnosis, and neighborhood education level. Breast-conserving surgery increased at similar rates among all racial/ethnic groups. Older age, Asian or Hispanic race/ethnicity, late-statge diagnosis, and residence in an undereducated neighborhood were factors associated with lower use of breast-conserving surgery. Conclusions. Although disparities are evident, use of breast-conserving surgery increased steadily in all groups examined in this study.
