- W3130035023 abstract "Abstract IntroductionBreast lymphoedema impacts the quality of life and cosmesis in women undergoing breast conserving surgery for cancer. The assessment of breast lymphoedema is complex and challenging. The varied reported incidence (0-94%) is due to lack of awareness, poor reporting, subjective characterisation, absence of standardised definitions and tools for diagnosis and monitoring. Extensive research has been done on secondary limb and trunk lymphoedema following lymph node surgery and/or radiotherapy. However, there is a lack of data on breast lymphoedema. Disruption of lymphatics due to advanced oncoplastic procedures, axillary surgery, modified incisions and adjuvant radiotherapy may contribute to this problem. The objective of this study is to identify the causes of delayed resolution of breast lymphoedema. Methods A retrospective audit was carried out in women who underwent breast conserving surgery between 2011-2017.Only patients with breast oedema, seen in the lymphoedema clinic were included in the study. Data on body mass index (BMI), types of incisions, breast procedures, axillary surgery, histopathology, adjuvant treatment including the extent of adjuvant radiotherapy was collated from the hospital database. Breast lymphoedema was diagnosed by clinical examination and/or by a Delfin lymph scanner (DLS). DLS is a mobile non-invasive device which uses tissue dielectric constant (TDC) for measuring subcutaneous tissue water. A reading of 45% or higher was accepted as indicative of breast lymphoedema in our unit. Percentage water content (PWC) value was recorded only in 55 patients using DLS. ResultsDuring the study period, 1905 patients underwent breast conserving surgery, out of which 120 (6.3%) were documented as having breast lymphoedema. The median time from surgery to assessment in the lymphedema clinic was 11 months. On univariate analysis, a high BMI (>30) and radiotherapy with boost lead to non-resolution of breast oedema. The median time taken for resolution of symptoms was 18 months. Other factors such as lateral skin crease incisions, single incisions to perform both breast and axillary surgery, oncoplastic procedures and re-excisions were not statistically significant. Using a DLS, the median PWC value was 56% in this cohort. Conclusions Our study shows that high BMI and radiotherapy with boost leads to delayed resolution of breast lymphoedema. The Delfin lymph scanner may be a potential tool for monitoring breast oedema but further prospective studies are required for validation of this tool.
