[Questionnaire Survey of Treatment for Elderly Breast Cancer in Yamaguchi Prefecture].

A questionnaire survey was conducted by 17 doctors from 14 hospitals regarding treating elderly breast cancer in Yamaguchi Prefecture. The survey items are the implementation status of the geriatric assessment(GA)for the elderly, the state at the start of treatment(fit/vulnerable/frail), and the setting of restrictions on the indication of surgery and drug treatment (endocrine therapy/chemotherapy/molecular targeted therapy). Only one institution(6%)was used for GA; the tools used were the G8 and Charlson comorbidity index. Regarding surgical treatment, most facilities did not set restrictions according to age or condition. Endocrine and molecular-targeted therapies(anti-HER drugs)are highly tolerated, and most facilities do not have age restrictions. On the other hand, 40% of the respondents set age restrictions on chemotherapy. Four(24%) therapists said they would limit their age to 70 to 75 if the patient had a frail condition. These results tended to be similar to the reports of NCD-registered elderly breast cancer treatment.
