Abstract

Background

Lipofilling is an increasingly popular technique for breast reconstruction following both mastectomy and breast conserving surgery. However, concerns remain over its oncological safety and its effect on cancer recurrence.

Method

A systematic literature review and meta-analysis was carried out. Patients who had undergone mastectomy and patients who had undergone breast conserving surgery (BCS) were looked at separately in order to investigate whether the addition of lipofilling had a significant effect on locoregional recurrence rate.

Results

Eleven studies were used in the analysis yielding a total of 2382 patients. For patients undergoing mastectomy (mean follow up = 36.2 months: range=12-90) or BCS (mean follow up = 30.2 months: range = 12-60) , the addition of lipofilling was not found to significantly affect the locoregional recurrence rate.

Conclusion

This meta-nalysis demonstrates that lipofilling is an oncologically safe procedure to be incorporated into breast reconstruction following either mastectomy or BCS for breast cancer. However a careful oncological follow up is recommended. In the future, more adequately- powered controlled clinical trials are needed in order to fully understand long term outcomes after lipofilling.
