title: [Adjuvant hormonal treatment for estrogen receptor-positive breast cancer-a questionnaire survey conducted by Japanese breast cancer society-authorized facilities in Hokkaido].
abstract: According to the Japanese Breast Cancer Society national breast cancer registration, 71.8%of breast cancer cases reported in 2004 and 79.8% of cases reported in 2010 were estrogen receptor(ER)positive. The frequency of ER-positive breast cancer is increasing annually in Japan. Many clinical trials have proven that adjuvant hormonal treatment affects both progression- free survival and overall survival in ER-positive breast cancer cases. However, some clinical questions remain, including those regarding the definition of preoperative hormonal treatment, appropriate dosage period, and therapeutic drug choice. In January 2013, we conducted a questionnaire survey of 53 medical doctors engaged in breast cancer treatment at 15 Japanese Breast Cancer Society-authorized facilities in Hokkaido. This survey included 6 clinical questions about preoperative hormonal treatment, 5 clinical questions about postoperative hormonal treatment for premenopausal breast cancer, and 4 clinical questions about postoperative hormonal treatment for postmenopausal breast cancer. We obtained replies from 35 medical doctors at 27 facilities. The response rate was 66%. We accumulated and analyzed these data. The discussion of questionnaire results in the medical administration field facilitates the sharing of information regarding differences in the approaches of different facilities to breast cancer patients. As a result, standardization of the breast cancer medical treatment system in this area has been accomplished.
