Introduction: Oncoplastic techniques can help maintain breast shape and position of nipple areolar complex (NAC) in tumours with a higher tumour to breast volume ratio. It is important to ensure long term oncological safety of these techniques. The aim of this study was to determine local recurrence rates and survival of oncoplastic BCS compared to standard operative techniques after long term follow up.
Methods: Between 1998 and 2013 all patients who had BCS at Institute Curie were reviewed. Data on cancer type, size, complications, surgery type, overall survival, local recurrence rates and metastatic incidence were recorded. Statistical analysis was performed using Student's t-test and Wilcoxon for categorical variables, λ2 and Fisher's exact test was used for continuous variable. Significance was set at P value<0.05.
Results: 962 patients has oncoplastic BCS (lateral mammoplasty, omega mammoplasty, superior or inferior pedicle reduction technique). 4371 patients had non-oncoplastic wide local excision. Oncoplastic BCS had loco-regional recurrence rates of 3.5% and 93.3% disease free survival after median follow up of 60 months. There was no difference between groups regarding local recurrence, disease free survival and overall survival at 5 year follow up.
Conclusion: Oncoplastic BCS does not affect locasl recurrence, disease free survival or overall survival compared to simple wide local excision technique for breast cancer
