    ABSTRACT: Background Fat grafting is widely carried out in breast cancer patients to improve quality in breast reconstruction. Recently, in vitro and animal studies have questioned the role of adipose tissues in cancer development.DesignsMatched-cohort study. We analysed: (i) 59 intraepithelial neoplasia patients who had undergone lipofilling, with no recurrence between primary surgery and lipofilling. (ii) A control group of 118 matched patients (two controls per lipofilling patient) with the corresponding recurrence-free intervals. Both groups were also matched for main cancer criteria. A local event (LE) was the primary end point, with follow-up starting from the baseline.ResultsMedian follow-up was 63 and 66 months from surgery, and 38 and 42 from baseline, for the lipofilling and control groups, respectively; the 5-year cumulative incidence of LE was 18% and 3% (P = 0.02). Ki-67 was the significant factor in univariate survival analysis. A subgroup analysis showed that lipofilling increased the risk of LE in women <50 years, with high grade neoplasia, Ki-67 ≥ 14 or who had undergone quadrantectomy.Conclusion Higher risk of LE was observed in intraepithelial neoplasia patients following lipofilling. Although further studies are required to validate our conclusions, patients belonging to this subgroup should be informed of these results and the potential risks.

    ABSTRACT: Paget's disease is a rare clinical and histological type of local recurrence (LR) after breast cancer treatment both in case of conservative surgery or nipple-sparing mastectomy (NSM) with or without intraoperative radiation. We performed an analysis of 861 NSM with electron beam intraoperative radiotherapy (ELIOT) patients treated at the European Institute of Oncology from 2002 to 2008, focused on Paget's disease local recurrence. In 861 patients (713 invasive carcinoma and 148 intraepithelial neoplasia), there were 36 local recurrences (4.18%), and among these were 7 Paget's disease local recurrences (0.8%). Median follow-up was 50 months. Four cases presented with nipple areola complex (NAC) erosions, two crusted lesions, and one ulcerated NAC. The average latency period from the NSM to Paget's disease local recurrence is 32 months (range, 12-49). Complete NAC removal was performed in all seven recurrences. The average follow-up after NAC removal was 47.4 months (range, 20-78). We found neither locoregional relapse nor metastatic event in this group. All patients were alive without disease. Paget's disease local recurrence can be found in a significant proportion after NSM. Any suspicious lesion on NAC requires prompt pathological confirmation. Primary carcinoma with ductal intraepithelial neoplasia or invasive ductal carcinoma with extensive in situ component, negative hormonal receptor, high pathological grade, overexpression of HER2/neu, and "HER2 positive (nonluminal)" subtype tend to be significantly associated with more Paget's disease local recurrence and should be followed carefully.

    ABSTRACT: The extended deep inferior epigastric perforator (DIEP) artery flap had been described in 1983. For head and neck reconstruction, we have been using a variation of this flap, namely a perforator free flap of the deep inferior epigastric system with a superolateral extension of the skin paddle. The purpose of this study was to present our 10-year experience in the performance of 102 soft tissue head and neck reconstructions with the extended DIEP flap in 100 patients. Depending on the reconstructive needs, we used the extended DIEP flap in 3 ways: as a cutaneous perforator flap (52.9%), as a chimeric perforator flap (6.9%), and as a myocutaneous perforator flap (40.2%). The overall flap survival rate was 97.1%. Three flaps (2.9%) totally necrosed. Partial flap loss occurred in 5.9% of the cases. The extended DIEP flap is reliable, has a safe vascular supply, and has a long pedicle. Its versatility makes it suitable for reconstruction of moderate to large head and neck reconstruction.
