The correlation analysis on invasive extent, which was evaluated by serial sections at an interval of 0.5 cm from 4 different directions taking the focus as the centre, and the tumor size, axillary lymph nodes metastasis, Her-2 gene overexpression, and his- tologic grading was processed. There was a significant correlation between invasive extent and tumor size （r=-0.766, P〈0.01）, and lymph nodes metastases 0=0.574, P〈0.01）, but there was no significant correlation between invasive extent and Her-2 expression （r=-0.106, P〉0.05）, and histologic grading （r=-0.228, P〉0.05）. The 100% negative rate of infiltration in patients without nipple discharge with tumor size 〈2, 2-3 and 〉3 cm was obtained at 1.5, 2.0 and 2.5 cm away from the tumor respectively. It is concluded that the performance of breast-serving surgery in patients with breast invasive ductal carcinoma should be evaluated by tumor size in combination with axillary lymph nodes involvement to decide the possibility of breast-serving and the secure excision extent.展开更多

Endoscopic subcutaneous mastectomy （ESM） plus immediate reconstruction with implants is an emerging procedure. The objective of this prospective study was to evaluate the clinical outcomes of these two surgical procedures in our clinical setting. Methods From March 2004 to October 2007, 43 patients with breast cancer underwent ESM plus axillary lymph node dissection and immediate reconstruction with implants, while 54 patients underwent BCS. The clinical and pathological characteristics, surgical safety, and therapeutic effects were compared between the two groups. Results There were no significant differences in the age, clinical stage, histopathologic type of tumor, operative blood loss, postoperative drainage time, and postoperative complications between the two groups （P 〉0.05）. The postoperative complications were partial necrosis of the nipple and superficial skin flap in the ESM patients, and hydrops in the axilla and residual cavity in the BCS patients. There was no significant difference in the rate of satisfactory postoperative cosmetic outcomes between the ESM （88.4%, 38/43） and BCS （92.6%, 50/54） patients （P 〉0.05）. During follow-up of 6 months to 4 years, all patients treated with ESM were disease-free, but 3 patients who underwent BCS had metastasis or recurrence -- one of these patients died of multiple organ metastasis. Conclusions After considering the wide indications for use, high surgical safety, and favorable cosmetic outcomes, we conclude that ESM plus axillary lymph node dissection and immediate reconstruction with implants -- the new surgery of choice for breast cancer -- warrants serious consideration as the prospective next standard surgical procedure.展开更多
