Abstract P4-10-13: Therapeutic Delays, Mode of Diagnosis and Surgical Treatment of Operable Invasive Breast Cancer (BC) in Elderly Versus Non Elderly Patients in the Community

Abstract

Abstract Background: National mammography screening program covers populations aged 50-74. We wondered whether breast cancer characteristics and treatment delays were influenced by age and screening method in a community-based breast unit. Patients and Methods: We analyzed complete data of prospectively recorded community operable breast cancer cases in a single regional cancer center between Jan 1st, 2005 and Oct 10th, 2007. Pts were eligible if they i. had a final diagnosis of invasive BC ii. were operated as first trt for BC, iii. had no history of other previous malignancy within the past 5 year period. Logistic regression analyses (SAS) were used to determine factors influencing delays between first description of the lesion and first appointment at breast unit. Results: 1044 pts met the inclusion criteria and had full data available. Age did not appear as a predictor of therapeutic delay, with both elderly and non-elderly pts having a median delay of 19 days between first screening/evidence of disease and 1st appointment at the breast unit. 59% of elderly and 65% of non-elderly pts had respectively had their breast cancer diagnosed through mammographic screening. As expected, mammographic screening as mode of discovery of the cancer was highest, among the 688 pts aged 50-74 (73%). Tumors characteristics and surgical treatment did not differ according to age categories elderly/non elderly as described in Table 1. Conservation rates were high in both populations. Conclusion: Despite absence of national mammographic screening program in elderly populations, patterns of screening and care appear efficient in a community-based setting, with absence of therapeutic delays, similar tumor staging and similar accesss to conservative surgery as compared to younger populations.
