Positive FDG uptake in the axilla does not always indicate axillary metastasis. US-guided FNAC is useful to avoid unnecessary ALND in patients with positive F-FDG uptake. However, SLN biopsy is needed in patients with negative US findings of the ALNs and those with negative FNAC.

We have described a novel technique using the wound retractor for SSM or NSM followed by IBR in treating breast cancer patients. This technique can minimize skin incisions without using disposable endoscopic instruments and improve the cosmetic outcome of the reconstructed breast.

An inappropriate skin incision on the breast reduces the cosmetic benefit of breast-conserving surgery (BCS). To improve the cosmetic outcome, we have performed "moving window" operation in which BCS can be performed via a periareolar incision (periareolar approach) and/or axillary incision (axillary approach) under direct visualization. Axillary lymph node dissection is also performed via an axillary incision. The periareolar and axillary approaches were used in 65 and 43 patients, respectively. Average operation time was 130 min in periareolar approach and 131 min in axillary approach. Average blood loss was 37 and 50 ml, respectively. Postoperatively, the surgical margin of breast tissue was histologically confirmed to be negative in 107 (99%) of 108 patients, one patients underwent subsequently reoperation because of positive surgical margin. Fifty-two patients (85%) in periareolar approach and 37 patients (86%) in axillary approach had excellent or good cosmetic results. With a mean follow-up of 36 months, four patients developed in-breast recurrence, but three of them had neoadjuvant chemotherapy before surgery. The moving window operation can improve cosmetic outcome of BCS without compromising oncological safety. Moreover, it can reduce operation time and blood loss in comparison to endoscope-assisted BCS.
