Abstract

This study used population-based tumor registry data to describe the patterns of adjuvant hormone therapy and to examine the correlates of hormone therapy for women with breast cancer. The study population included 5101 women (age 20 years) who were diagnosed with breast cancer in 1991 through 1997 in the entire state of New Mexico. Overall, 32% of women with stage I, II, or IIIA breast cancer received adjuvant hormone therapy. The likelihood of receiving adjuvant hormone therapy increased with tumor stage at diagnosis. Women less than 50 years of age were significantly less likely to receive adjuvant hormone therapy compared to those age 50 to 54 years, but there was no significant difference in the use of adjuvant hormone therapy for women age 55 years and older. The use of adjuvant hormone therapy was influenced by hormone receptor status and lymph node status. Patients who received adjuvant chemotherapy were also more likely to receive adjuvant hormone therapy than those who did not. The use of adjuvant hormone therapy alone was relatively stable over time and the use of adjuvant chemotherapy alone increased, but the receipt of chemotherapy combined with hormone therapy decreased from 1991 to 1997. There was no significant difference with age in the use of adjuvant hormone therapy among 55-year-old women compared to those age 50 to 54 years, whereas women less than 50 years of age were significantly less likely to receive this therapy. The use of adjuvant hormone therapy varied significantly by tumor stage, lymph node status, hormone receptor status, and the receipt of adjuvant chemotherapy.
