Attitudes towards breast conservation in patients aged over 70 with breast cancer

Background: The majority of breast conserving surgery (BCS) is performed in younger women. There is little published information about the views of women aged over 70 regarding BCS. The aim of this study was to investigate the attitudes of this age group towards BCS, and factors which may influence their treatment decision-making. Methods: A questionnaire was sent to all patients who were aged 70 or over at the time they had breast cancer surgery in NHS Lanarkshire between 1999 and 2013. This detailed surgical options and recommendations, timing of decision making, treatment expectations, psychological and cosmetic concerns and other factors which may have influenced any decision made e.g. travel for radiotherapy and potential side effects. Results: Responses were received from 339 patients, 192 of whom had a mastectomy with the remaining undergoing BCS. In the mastectomy group 18 % (35) would have preferred to have BCS had it been an option, with 40 % (76) of group being happy to take neoadjuvant endocrine therapy to try and facilitate this. However, only 14 % (26) of patients would have considered neoadjuvant chemotherapy with the same aim. Almost half (82) of the mastectomy patients said that the risk of local recurrence following BCS was a factor which influenced their decision. Conclusion: BCS is something that patients aged over 70 are interested in considering in the same way as younger patients. More than a third of patients requiring mastectomy would be willing to take neoadjuvant endocrine therapy to attempt to downstage their tumour to facilitate BCS.
