To assess the rates of breast cancer detected in postoperative surveillance mammograms in women70 Years and overall mortality in this age group.Four hundred and ninety-eight patients were identified retrospectively from a database from a single large UK hospital. Patients were included in the study if they were female, aged70 years at diagnosis of either invasive breast cancer or ductal carcinoma in situ (DCIS), had surgical treatment between 1 January 2010 and 31 December 2014, and no previous diagnosis of breast cancer. Statistical analysis was performed using Excel, using the XThe mean age of women included in this study was 77 years. The mean number of postoperative surveillance mammograms performed per patient was 4.2. In the 5-year follow-up, there was a local recurrence rate of 1.9% (n=6) and a contralateral breast cancer rate of 1% (n=6). The 5-year overall mortality rate was 17.7% (n=88), and the 5-year breast cancer-specific mortality rate was 7.2% (n=36).This study demonstrated low local recurrence and contralateral breast cancer rates during the 5-year follow-up period. Clear discussions therefore need to be held with older patients about the value of postoperative mammographic surveillance. Further research is required regarding patient opinion and experience to help develop more consistent guidelines.
