Level 2 Oncoplastic Surgery for Lower Inner Quadrant Breast Cancers: the LIQ-V Mammoplasty

Background: Oncoplastic surgical techniques offer an option of breast conserving surgery for larger tumors with the use of glandular reshaping to prevent postoperative deformity. A technique for the excision of lower inner quadrant tumors via a V incision is described, the lower-inner quadrant-V (LIQ-V) mammoplasty, and the results of a pilot study are reported.

Methods: Retrospective collection of pre- and postoperative data was collected from patients undergoing a LIQ-V mammoplasty for a LIQ tumor.

Results: Twenty-two patients were operated on between 2004 and 2011 at a mean age of 58 years. The mean follow-up was 55 months. The mean resection weight was 101 g for tumors ranging in size from 4 to 31 mm. The margins were clear in 95% of cases. There was one case of local recurrence and metastatic disease. The cosmetic outcome was judged as excellent in 68% of cases, and no patient required further ipsilateral or contralateral symmetrizing surgery.

Discussion: The deformity often associated with tumors of the LIQ is adequately addressed by this new technique. It has a complication rate comparable to other mammoplasty series and a high rate of clear resection margins. Many oncoplastic surgery techniques are based on inverted T mammoplasty, but these are not suited for all tumor locations. The LIQ-V mammoplasty is an adaptation of the standard techniques that best suit the LIQ. It is oncologically safe and provides disease-free margins, and although the resection volumes are large, the cosmetic outcome is not compromised.
