Objective To investigate the effect of operation incision selection on the success rate of sentinel lymph node biopsy and subcutaneous hydrops in breast cancer.
Methods A retrospective analysis of 132 cases of breast cancer were enrolled from the Third Hospital of Nanchang from 2011 to 2013. Sixty-nine cases received breast plus axillary incision surgery, and 63 cases received breast extended to axillary incision surgery. The detection rate of sentinel lymph nodes, incision drainage time and the incidence of subcutaneous effusion were compared between both groups.
Results The successful rate of sentinel lymph node detection in single incision group and double incision group were 96.8% and 97.1%, respectively(P>0.05). When the sentinel lymph nodes were negative, the difference of drainage time between two groups had no statistical significance (P>0.05), the incidence of axillary hydrops of double incision group and single incision group were 23.8% and 7.5% (P<0.05); while when the sentinel lymph nodes were positive, the difference of drainage time between two groups had statistical significance (P<0.05). The incidence of axillary hydrops between two groups were 28.0% and 23.8% (P<0.05).
Conclusion Preoperative axillary lymph node assessment is helpful for negative patients to select single incision, which is beneficial to reduce the incidence of postoperative subcutaneous effusion and drainage time in comparison with double incision group. As for positive patients, preoperative axillary lymph node assessment has no effect on the incidence of postoperative subcutaneous effusion or the time of tube between two types of surgical incision.
