乳腺癌术后即刻乳房重建肿瘤安全性探讨

即刻乳房重建在避免病人接受二次手术的同时，可以减轻病人失去乳房的心理创伤。但是，肿瘤外科医生在选择即刻乳房重建时必须保证肿瘤的安全性，术前细致的评估、术中足够完整的腺体切除是保证肿瘤安全性的前提。美国国家综合癌症网络（NCCN）指南明确指出，炎性乳腺癌是即刻乳房重建的禁忌证，此外，对于拟行术后放疗的病人也需慎重选择即刻乳房重建；尽管缺乏高级别循证医学证据，但现有的数据显示，即刻乳房重建并不影响术后辅助化疗的疗效，部分病人选择保留乳头乳晕的皮下腺体切除是安全可靠的，假体植入术后的淋巴瘤虽有报道，但发病率很低。因此，乳房切除术后即刻乳房重建在适宜的乳腺癌病人中是安全可靠的手术方式。     

Endoscopic-assisted subcutaneous mastectomy and axillary dissection with immediate mammary prosthesis reconstruction for early breast cancer

BACKGROUND: Endoscopic surgery has been applied successfully in breast lump excision, breast augmentation, subcutaneous mastectomy for gynecomastia, and axillary dissection. Since subcutaneous mastectomy has been proven to be oncologically safe for early breast cancer, we have sought to develop a reproducible minimally invasive endoscopic-assisted technique to address this condition. METHODS: Between December 1998 and May 1999, endoscopic-assisted subcutaneous mastectomy and axillary dissection with immediate reconstruction using a mammary prosthesis was performed in nine patients with early breast cancer at the Prince of Wales Hospital, Hong Kong. A 5-cm skin incision was made along the line of the lowest axillary skin crease. Dissection was continued down to the lateral border of the pectoralis major muscle. A subpectoral pocket was gently created by an endoscopic breast dissector. The endoscopic breast retractor and 10-mm/30 degrees scope were introduced into the subpectoral pocket, and further dissection was carried out using a 7-in harmonic scalpel under endoscopic vision down to a level 1 cm caudal to the inframammary fold. This subpectoral space was used for the insertion of the mammary prosthesis later on. Endoscopic-assisted subcutaneous mastectomy was performed afterward. Combined level I and level II axillary dissection was carried out via the same incision under direct vision. RESULTS: Apart from minor skin flap bruises in our first two patients, there were no major complications. Histological examination of all the specimens showed clear margins. Postoperative radiotherapy and chemotherapy were given in the usual manner. All patients were satisfied with the reconstructive outcome. CONCLUSIONS: We have described a novel endoscopic technique for subcutaneous mastectomy with immediate mammary prosthesis reconstruction in treating early breast cancer patient. This technique can minimize skin incision, reduce blood loss, and improve reconstructive outcome. It is easy to learn and well accepted by patients.     

The influence of radiotherapy on skin circulation of the breast after subcutaneous mastectomy and immediate reconstruction.

The skin circulation was measured in 43 breast cancer patients following subcutaneous mastectomy and immediate reconstruction with a prosthesis, at least 1 year after radiotherapy (46 Gy) following surgery (19 patients) or if no radiotherapy was given, at least 1 year postoperatively (24 patients). The skin circulation was measured by laser Doppler fluxmetry (LDF) and fluorescein flowmetry within three areas: 2 cm above the border of the areola, within the nipple-areola complex, and 2 cm below the border of the areola. The results show that there was no reduction in skin circulation. On the contrary LDF and fluorescein flowmetry showed in the operated breast an increased circulation in the nipple-areola complex in the irradiated breast compared with the non-irradiated by 26% and 30%, respectively (P < 0.05). The results indicate that radiotherapy following subcutaneous mastectomy and immediate reconstruction with a prosthesis does not lead to long-term reduction in basal skin circulation in the breast.     

Breast reconstruction following mastectomy for cancer.

Breast reconstruction following mastectomy for cancer is a feasible procedure. The selection of the proper type of mastectomy should be the decision of the cancer surgeon. However, with the advent of modified mastectomies, the use of fewer primary skin grafts, and the preservation of all or part of the pectoralis major muscle, breast reconstruction has become more satisfactory. Since many women adjust poorly to mastectomy, the chance for reconstruction offers hope for a fuller life. Reconstruction of the postmastectomy cancer patient can be accomplished in three basic steps: 1) An adequate breast mound can be constructed with a prosthesis. A flap may be used if the skin cover is inadequate. 2) The size and shape of the remaining breast can be adjusted to obtain symmetry. 3) The nipple-areola complex can be reconstructed if the patient desires. Correction of the infraclavicular and axillary defects may be required. The techniques employed in 14 patients are presented.

Complete tissue expander coverage by musculo-fascial flaps in immediate breast mound reconstruction after mastectomy

Abstract

Immediate breast reconstruction with tissue expander has become an increasingly popular procedure. Complete coverage of the expander by a musculofascial layer provides an additional well-vascularised layer, reducing the rate of possible complications of skin necrosis, prosthesis displacement, and the late capsular contracture. Complete expander coverage can be achieved by a combination of pectoralis major muscle and adjacent thoracic fascia in selected patients. Seventy-five breast mounds in 59 patients were reconstructed, in the first stage a temporary tissue expander inserted immediately after mastectomy and a musculofascial layer composed of the pectoralis major muscle, the serratus anterior fascia, and the superficial pectoral fascia were created to cover the expander. The first stage was followed months later by implant insertion. Minor and major complications were reported in a period of follow-up ranging from 24–42 months (mean 31 months). Complete musculofascial coverage of the tissue expander was a simple and easy to learn technique providing that the patient has a well-formed and intact superficial pectoral and serratus anterior fascia. From a total of 75 breast mounds reconstructed, major complications rate was 4% (overall rate of 19.8%), including major seroma (n = 4), haematoma (n = 1), partial skin loss (n = 3), wound dehiscence (n = 1), major infection (n = 2), severe capsule contracture (n = 1), and expander displacement (n = 3). The serratus anterior fascia and the superficial pectoral fascia flaps can be effectively used as an autologous tissue layer to cover the lower and the lateral aspect of tissue expanders in immediate breast reconstruction after mastectomy.     

Use of mesh to repair the submuscolar pocket in breast reconstruction: a new possible technique

The reconstruction of the female breast after mastectomy has become a crucial part of primary breast cancer therapy. Setting of an implant is possible only in case of locally abounding soft tissue coverage and when no radiation has before performed. It is necessary a complete integrity of the submuscolar pocket and good blood supply of the skin to avoid failure of the procedure. In Author's experience, started since 1994, an immediate breast reconstruction after mastectomy is performed using gel-silicon implants directly when it was possible or setting first an expander. In six cases the condition of major pectoralis muscle after mastectomy was so foul that an immediate breast reconstruction with prosthesis was not realizable. However, the Authors tried a new technique using polypropylene mesh sutured on the major pectoralis muscle to cover the muscle partially destroyed. Preliminary data from the 6 pts seems to be encouraging.

Inferolateral AlloDerm hammock for implant coverage in breast reconstruction

PURPOSE: Implant reconstruction is commonly performed to reconstruct mastectomy defects or to correct breast hypoplasia. We have been using an inferolateral AlloDerm hammock as an inferior extension of the pectoralis major muscle to provide a mechanical barrier between the implant and skin and to control implant position. METHODS: The inferior border of the AlloDerm hammock is attached inferiorly to the rectus abdominis fascia and laterally to the serratus anterior fascia to create the borders of the implant pocket. The AlloDerm is then sewn to the pectoralis major muscle to enclose the implant. RESULTS: The AlloDerm hammock was used in 43 patients and 67 breasts for immediate expander-implant reconstruction (10), immediate silicone implant reconstruction (30), delayed expander-implant reconstruction (4), and revisional implant reconstruction for capsular contracture following capsulectomy (23). The AlloDerm hammock allowed complete coverage of the implant and symmetric positioning of the inframammary fold. In delayed reconstructions with existing skin redundancy at the mastectomy site, inferior epigastric tissue was recruited and tissue expanders filled over 75% of the desired volume, thus decreasing the need for subsequent filling. Patients were overall satisfied with their results and had few complications. No capsular contracture, hematoma, or seroma was observed in 6 months to 3 years of follow-up. CONCLUSION: Implant reconstruction with an inferolateral AlloDerm hammock facilitates positioning of the implant in immediate or revisional breast reconstruction and simplifies expander-implant reconstruction. This safe technique is easy to learn and should be considered a viable option for breast reconstruction.     

The circulation in the nipple-areola complex following subcutaneous mastectomy in breast cancer.

To evaluate the decrease in circulation in the nipple-areola complex after subcutaneous mastectomy and immediate implantation of a submuscular prosthesis, the blood flow was studied by both fluorescein flowmetry and laser Doppler flowmetry in 24 patients with invasive breast cancer. In 14 patients a lazy-S-shaped horizontal lateral incision was used, and 10 underwent a subcutaneous reduction mammaplasty. After subcutaneous mastectomy with a lazy-S incision there was no significant decrease in blood flow in the nipple-areola complex compared with that in the untreated contralateral breast. In the breasts in which reduction mammaplasty had been done, the blood flow was reduced by 74% as measured by fluorescein (p less than 0.01), and 70% by laser Doppler flowmetry (p less than 0.05), compared with the contralateral breast. Five patients had partial or complete epidermal, and one patient had total dermal, necrosis of the complex, but there was no deep necrosis. No fluorescence was seen within the areas in which necrosis later developed in any of these six cases. The laser Doppler signal in the corresponding areas, however, was not reduced. The results show that the circulation in the nipple-areola complex is reduced more after subcutaneous reduction mammaplasty than after subcutaneous mastectomy with a lazy-S incision.
