Abstract

Abstract:

Objective

To explore the effect of internal mammary node （IMN） dissection with videoassisted thoracoscopic surgery （VATS） on staging and treatment for breast cancer patients.

Methods

Fiftytwo patients with breast cancer whose tumors located in the internal or medial portion of the breast were collected in Cancer Center of Sun Yat-sen University from Nov.2001 to Nov.2006.IMN dissection with VATS was performed after mastectomy.The change of pathologic staging and disease-free survival （DFS）were analyzed after operation.

Results

Of the 52 patients， 20 （38.5% ） had IMN metastasis.In these cases， 6 cases（11.5% ） had only IMN metastasis， 5 cases （9.6% ） had IMN metastasis and 1 to 3 axillary nodes metastasis， and 3 cases（5.8% ） had IMN metastasis and 4 to 9 axillary nodes metastasis， and 6 cases（11.5%） had IMN metastasis and ≥10 axillary nodes metastasis.Twenty cases （38.5% ） changed pathologic staging after internal mammary node dissection with VATS.The 1-， 2-， and 3-year DFS was 100% ， 94.3% ， and 86.2%respectively.

Conclusions

IMN dissection by VATS can not only define the pathologic staging， guide the treatment， but also decrease the locoregional recurrence of breast cancer with tumors located in the internal or medial portion of the breast.
