Comparison of mastoscopic and conventional axillary lymph node dissection in breast cancer: long-term results from a randomized, multicenter trial.


ABSTRACT:

Objective

To compare the long-term results of mastoscopic axillary lymph node dissection (MALND) and conventional axillary lymph node dissection (CALND).

Patients and methods

From January 1, 2003, through December 31, 2005, a group of 1027 consecutive patients with operable breast cancer were randomly assigned to 1 of 2 study groups: MALND and CALND. The median follow-up was 63 months. The primary end points of the study were operative outcomes, complication reduction, function conservation, and cosmetics. The secondary end points were disease-free and overall survival.

Results

The mean operative blood loss in the MALND group was less than in the CALND group (P<.001). The patients who underwent MALND had less axillary pain, numbness or paresthesias, and arm swelling (P<.001). The aesthetic appearance of the axilla in the MALND group was much better than that in the CALND group (P=.001 at 6 months and P=.002 at 24 months). A significant difference was found between the 2 groups in distant metastasis (P=.04). The disease-free survival rate was 64.5% in the MALND group and 60.8% in the CALND group (P=.88). The overall survival rate was 81.7% in the MALND group and 78.6% in the CALND group (P=.95).

Conclusion

Compared with CALND, MALND has advantages in operative outcomes, complication reduction, function conservation, and cosmetics.
