Background: Nipple sparing mastectomy (NSM) can be performed for prophylactic mastectomy and the treatment of selected breast cancer with oncologic safety. The risk of skin and nipple necrosis is a frequent complication of NSM procedure, and it is usually related to surgical technique. However, the role of the breast morphology should be also investigated. Method: We prospectively performed an analysis of 124 NSM from September 2012 to January 2013 at the European Institute of Oncology, Milan, Italy, focusing on necrotic complications. We analyzed the association between the risks of skin necrosis and the breast morphology of the patients. Results: Among 124 NSM in 113 patients, NSM procedures were associated with necrosis in 22 mastectomies (17.7%) among which included partial necrosis of nipple-areolar complex (NAC) in 15 of 124 NSM (12.1%) and total necrosis in 4 cases (3.5%). The NAC was removed in 5 NSM cases (4%). The volume of breast removed was the only significant factor increasing the risk of skin necrosis. The degree of ptosis was not significantly related to the necrosis risk. Conclusions: Large glandular specimen increases the risk of NAC necrosis. The degree of ptosis and the distance between the sternal notch and the NAC have no significant impact on necrotic complications in NSM. To reduce the necrotic complications in large breast after NSM, reconstruction should better be performed with autologous flap or slow skin expansion using the expander technique.

Summary: Secondary correction of nipple areola complex (NAC) malposition represents a major concern after breast reconstructive procedures. It is frequently requested by patients complaining about asymmetric areolas impairing the whole reconstructive procedure and asking for improved cosmetic outcomes. Several methods have been described to achieve a good symmetry between the 2 areolas, either natural or reconstructed. We describe our correction technique with free NAC graft. A total of 16 patients were treated with free NAC grafts between April 2010 and April 2013 at the European Institute of Oncology, Milan, Italy. This series focused on the surgical technique and its postoperative outcomes. Three cases of partial graft loss (18%) were observed in the postoperative period. No total NAC necrosis occurred. No infection was observed. All the complications were managed with a conservative treatment, not requiring any further surgery. NAC malposition following breast reconstructive procedures can be corrected using the technique of free NAC graft with reliable and satisfactory results.

The objective of the present study was to determine the effectiveness and reliability of sentinel lymph node biopsy (SLNB) performed under local anesthesia (LA) for patients with breast cancer, by comparing the results with those obtained under general anesthesia (GA). Between January 2006 and February 2007, SLNB was performed under LA or GA in 37 and 94 patients with clinical Tis, T1, T2 or T3 N0 breast cancer, respectively. All underwent radiocolloid and blue dye injections to identify sentinel nodes. The sentinel node detection rate, the number of nodes harvested and the number of positive nodes were compared between the two groups. The sentinel node identification rates were similar for both groups. The number of sentinel and axillary nodes removed and number of positive nodes did not differ significantly between the two groups. SLNB performed under LA is an effective and reliable alternative to SLNB done under GA.

Background: Lipofilling is widely used in breast reconstruction after mastectomy with reconstruction or breast conserving surgery in patients with breast cancer. The aim of this study is focused on complications associated with lipofilling in elderly breast cancer patients with breast defects after breast conserving surgery or reconstruction. Methods: A total of 137 patients older than 60 years who underwent 153 lipofilling procedures were included. All patients had undergone breast lipofilling using Coleman’s technique. Estimated breast defect volume, lipofilling volume, and complications after lipofilling were obtained for analysis. Results: Most patients (67%) had only 1 lipofilling procedure. The median lipofilling volume to breast defect volume ratio was 1.5. No severe complications were found after treatment. Liponecrosis was detected in 10 of 153 breasts (7%) or 9 of 137 patients within 2 weeks after lipofilling and required surgical drainage in 2. No local recurrences were noted. Conclusions: The incidence of liponecrosis after lipofilling in elderly patients was relatively high, requiring surgical drainage in some cases. As a rough guide, the lipofilling volume should not exceed 1.5 times the defect volume, and close postoperative follow-up within the first 2 weeks is suggested for these patients.

The concept of breast cancer treatment is changed from maximal tolerable treatment to minimal effective treatment. There has been a change from axillary lymph node dissection (ALND) to sentinel lymph node biopsy (SLNB). The current theory of breast cancer spreading to the axillary lymph nodes is established that if the metastatic cancer cell has spread to the axillary lymph node.

Resection of large tumors can be challenging, from the view point of breast preservation. Oncoplastic techniques are a valuable component of breast surgery in patients with large breast tumors who desire breast preservation. These techniques have been shown to be oncologically safe, while maintaining acceptable breast cosmesis. For locally advanced or recurrent breast cancers, the goals of surgery include local disease control and palliation of clinical symptoms. Oncoplastic surgery is also effective and oncologically safe in these situations. The need to completely remove all foci of cancers with adequate surgical margins often requires the displacement of adjacent or distant skin and soft tissue to cover the resulting soft tissue defect. Sometimes doing so can be cosmetically pleasing as well. In this article we present three special therapeutic problems in three distinct conditions, all resolved with oncoplastic techniques: the benign breast condition, malignant breast condition, and the palliative setting.

Background: Breast reconstruction with pedicled transverse rectus abdominis myocutaneous (TRAM) flap can result in significant abdominal wall donor-site morbidity. We present our technique of transversely dividing the anterior fascia and rectus abdominis combined with reinforcement above the arcuate line for closure of the anterior abdominal wall defect to prevent contour deformities performed by a single senior surgeon and compare these results with those of our prior series. Methods: We described our new technique of closure of the abdominal wall defect and retrospectively performed the comparison between the results of pedicled TRAM flaps using the new closure technique and those of 420 pedicled TRAM flaps from our 2003 publication in terms of abdominal bulging and hernia. Results: Sixty-seven pedicled TRAM flaps in 65 patients were compared with 420 pedicled TRAM flaps of the 2003 series. The new technique was associated with 5 partial TRAM flap necroses (8%). There was no total flap loss with the new technique. The median follow-up period was 13 months (range, 4–36 months). There were no instances of abdominal hernia and bulge during follow-up in the new series. Compared with the previous 2003 series, the new technique was superior in terms of occurrence of abdominal wall hernia or bulging. Conclusions: We are still performing pedicled TRAM flap for autologous breast reconstruction. Using the technique of transversely dividing the anterior fascia and rectus abdominis combined with reinforcement above the arcuate line can reduce the occurrence of abdominal bulging and hernia.

BACKGROUND To determine the risk factors for disease recurrence after breast conserving therapy (BCT) for breast cancer in a group of South-East Asian women. METHODS Medical and pathological records of women who underwent BCT during the 10-year period from 2001 to 2010 were reviewed. Data collected included age ≤35 years defined as the young, type of operation, pathological data, hormonal receptor (HR) status, human epidermal growth factor receptor-2 (HER-2) expression status, and surgical margin status. Data on adjuvant therapy were also collected. Main outcomes were overall breast cancer recurrence, locoregional, and distant recurrence. Risk factors for each type of recurrence were identified using Cox proportional hazards regression models. RESULTS There were 294 BCTs in 290 patients during the study period. The overwhelming majority (91%) had early stage (stages I-II) breast cancers. Young age patients constituted 9% of all patients, and triple negative cancers (HR negative and HER-2 negative) were seen in 19%. Involved margins on initial surgery were found in 9% of cases, and after reoperation, only 2% had involved margins. After a median follow-up of 50 months, and a maximum follow-up of 135 months, there were 30 recurrences and 6 deaths. Of the 30 recurrences, 19 included locoregional, 20 included distant, and 13 had in-breast recurrences. The disease-free survival at 10 years was 82.5% (95% CI: 74.8% to 88.1%), and the cumulative in-breast recurrence was 9.3% (95% CI: 4.9% to 17.2%) at 10 years. Multivariable Cox regression analysis revealed that young age, larger tumor size, involved margins, and no breast irradiation were associated with higher risk of locoregional recurrence. Triple negative status, larger tumor size, more positive nodes, and involved margins were associated with higher risk of distant recurrence. CONCLUSIONS We found young age to be a significant prognosticator of locoregional recurrence, and triple negative status of distant recurrence. Involved surgical margin status was associated with both recurrences. Tumor size was associated with both recurrences, and axillary lymph node metastasis was associated with distant recurrence.

Free Nipple Graft Technique for Correcting a Malpositioned Nipple After Breast Procedures

Prakasit Chirappapha; Mario Rietjens

Secondary correction due to the malpositioned nipple-areolar complex (NAC) has been a major concern after certain breast reconstructive procedures. It is frequently requested by patients complaining about asymmetric areolas impairing the whole reconstructive procedure and asking for improved cosmetic outcomes. Several methods have been described to treat this problem. We describe our correction with free NAC graft technique.
