To investigate the therapeutic effect of anthracycline chemotherapy in advanced breast cancer and its influence on estradiol and tumor size, 136 breast cancer patients in Shan Xi Bethune Hospital were divided into anthracycline chemotherapy group and non anthracycline chemotherapy group. The clinical effects of anthracycline chemotherapy group and non-anthracycline chemotherapy group were observed. The levels of estrone, estradiol and follicle stimulating hormone before and after treatment were measured. The tumor size, adverse reactions and 2-y survival rate of anthracycline chemotherapy group and non anthracycline chemotherapy group were measured after 1-3 courses of treatment. The total effective rate of anthracycline chemotherapy group and non-anthracycline chemotherapy group was 64.7 and 23.5 %, respectively and the total effective rate of non anthracycline chemotherapy group was significantly lower than that of anthracycline chemotherapy group (p 0.05). After treatment, the tumor volume of each group gradually decreased with increased time of drug exposure and the degree of tumor reduction in the non-anthracycline chemotherapy group was lower than that of the anthracycline chemotherapy group (p 0.05). After 2 y of follow-up, the survival rate of anthracycline chemotherapy group was significantly higher than that of non-anthracycline chemotherapy group (p<0.05). The effect of anthracycline on advanced breast cancer was better, the level of serum estradiol decreased, and the volume of tumor decreased.
