We report a case of advanced BC in a 62-year-old male treated at our interdisciplinary Breast Cancer Center. The patient presented with a newly diagnosed large, symptomatic mass in his left breast. Clinical examination showed a not movable mass of 16 cm diameter, deforming the whole breast; the overlying skin was livid and hypervascularized. Enlarged lymph nodes were palpable in the axillary pit. He had no concomitant diseases at time of presentation. He denied any first- or second degree family medical history of cancer of any type and he never received radiotherapy. Ultrasound guided minimal-invasive 14-gauge core biopsy revealed a moderately differentiated encapsulated papillary carcinoma with high expression of estrogen and progesterone receptors(both > 80%, IRS 12) and HER2-negative. Because of the tumor size a mastectomy with axillary dissection and chest wall reconstruction using a latissimus dorsi flap was performed. Histological analysis showed invasive growth besides typical(non-invasive) papillary carcinoma and was classified as invasive solid papillary carcinoma; p T3(10 cm), p N0(0/15), M0,R0; Oncotype DX Recurrence Score indicated low risk(RS: 2). After discussion in the interdisciplinary tumor board meeting, radiation therapy and tamoxifen were recommended. The patient had an uneventful recovery and is disease-free after two years of follow-up. Male BC is typically diagnosed at an advanced stage, most likely due to a lack of awareness that men can develop BC. Therefore, in case of a large tumor, a flap-based thoracic reconstruction may be required.展开更多

This study was conducted in Chinese patients to determine whether stable cases of seromas would resolve without treatment. Methods： A retrospective review of 45 consecutive cases of immediate breast reconstruction with LD flap from April 2012 to February 2017 was conducted. The scope of the seroma was demarcated with a marker pen, and cases that remained stable over time （i.e. the size of the seroma did not increase） were observed without treatment. The measured outcomes included the incidence ofseromas, the volume and duration of postoperative wound drainage, and other demographic characteristics. Results： Twenty-four patients （53.3%） developed a seroma at the donor site. Of these, 21 patients （87.5%） did not require treatment, and the seroma resolved over time. The mean duration of a sustained serol-na was 6.8 ± 1.4 weeks （range： 4-9 weeks）. Conclusions： This study observed the scope and progression of the seromas and found that seromas at the LD donor sites resolved over time without treatnlent.展开更多

Methods： From Jan. 2000 to Jul. 2005, 74 staged 0-II patients （mean age 39） were performed immediate breast reconstruction with autologous tissue either using LTD flaps or pedicled TRAM flaps with supplemental implants when necessary after mastectomy due to breast cancer and the charts were reviewed. Results： The age, marriage and menses status did not affect the selection of modalities and the need of implants. In 74 patients, 62 cases （83.8%） were performed LTD reconstruction with 13 implants and 12 cases received TRAM with 1 implant. The difference in need of implants or not between the two modalities had no statistical significance （P=0.442, Fisher＇ exact test）. Aesthetic results judged as good or fair were in 88% patients and the cosmetic effects between LTD and TRAM groups or implant and non-implant groups had no differences. All reconstructions were successful, with 4.1% cumulative locoregional recurrence and 100% overall survival by following up to 66 months （median 9 months）. The DFS and RFS between the two modalities had no significant differences by log rank test. Conclusion： Immediate autologous tissue reconstruction makes it possible to regain the natural and symmetric contour of breast without increased local recurrence. The LTD flap reconstruction is a suitable option for most Chinese women as well as the pedicled TRAM flap.展开更多

We evaluated both oncologic and aesthetic outcomes in addition to the related complications of this flap as an adjunct to breast conserving surgery in the management of breast cancer patients. Methods: All patients underwent a one-stage procedure with immediate reconstruction through two-steps operation;wider local excision utilizing oncoplastic principles and mini flap harvest & volume replacement. Results: The study included 34 cases with early breast cancer;30 patients had partial breast resection and defect refilling by LD mini-flap, three patients underwent mastectomy and one patient underwent extended LDF. The mean defect volume was (212.63 cm<sup>3</sup> ± 59.57) cm<sup>3</sup>, while the mean flap volume was (218.27 cm<sup>3</sup> ± 53.64 cm<sup>3</sup>). Patient self-evaluation of the cosmetic outcome was excellent in 20%, good in 60% and satisfactory in 20% of patients. Panel evaluation according to Harvard scale showed excellent in 36.7%, good in 36.7%, fair in 26.7% of patients. The median hospital stay was 4 days. The postoperative complications included wound gap in 4 patients (13.3%), postoperative donor site seroma in 16 patients (53.3%). No flap loss or necrosis, no affection on arm or shoulder mobility occurred. Lastly, no tumor recurrence till now. Conclusion: Latissimus dorsi mini-flap can achieve adequate cosmetic and oncologic outcomes with a low incidence of complications in patients with early stage (I/II) breast cancer and small to medium sized breasts.展开更多

Extra thoracic skeletal muscle transposition especially latissimus dorsi muscle flap (LDMF) had been used to prevent this complication. The aim of this study was to assess the effectiveness of LDMF in preventing BPF developing after extrapleural pneumonectomy (EPP) and external radiation therapy in malignant pleural mesothelioma (MPM). Methods: Between May 1999 and Dec. 2008, 37 patients with MPM were operated upon by EPP using LDMF prophylactically to reinforce the bronchial stump, and then received external radiation therapy with or without postoperative chemotherapy. Results: The mean age of all patients was 46.7 (range 26-57) years. Twenty five patients were males and 12 patients were females. Twenty three patients had MPM of the right side and 14 patients had MPM of the left side. The peri-operative mortality was 2.7% and only few flap related postoperative morbidity were reported in the form of minor seroma and subcutaneous surgical emphysema. The median follow up was 17 (range 9-43) months. All cases completed their postoperative external radiation therapy with no reported cases of early or late BPF. Conclusion: Intrathoracic pedicled LDMF transposition is proved to be effective in prevention of BPF developing after EPP and external radiation therapy in MPM and it is advised to be a routine step in EPP in these cases and to use more sophisticated technique of postoperative external beam radiotherapy (3D conformal or IMRT) to minimize this complication.展开更多
