Influence of resection volume on locoregional recurrence of breast cancer after breast-conserving surgery.
BACKGROUND
The goals of breast-conserving surgery are to provide the survival equivalent of mastectomy, a cosmetically acceptable breast and a low rate of locoregional recurrence in the treated breast. This retrospective study investigated the impact of the resection volume on locoregional recurrence after breast-conserving therapy in patients with early-stage invasive breast cancer.


METHODS
Retrospective data from 185 women who were treated for operable breast tumours by breast-conserving surgery between 1995-1999 at the Martin-Luther-University in Halle/Germany were included in our study. Extent of total resection volume (TRV), tumour volume (V) and difference volume (DV) was compared for the influence on locoregional recurrence.


RESULTS
Our data showed no significant correlation between the risk of locoregional recurrence and the extent of resection volume. Predictors of an increased risk of locoregional recurrence after breast-conserving surgery were large primary tumour, grading, lymphatic vascular invasion, hormone receptor status and lack of radiotherapy or hormonal therapy.


CONCLUSIONS
According to the accuracy of locoregional disease control and maintenance of the breast's shape, our results support conservative surgery in early-stage breast cancer followed by radiotherapy and adjuvant systemic therapy.
