Issues related to choice of breast reconstruction in early-stage breast cancer

Immediate breast reconstruction using latissimus dorsi muscular flap: A retrospective study of Chinese patients with breast cancer

Reconstruction of breast defects of patients who underwent mastectomy can be challenging. This study was designed to review a series of 43 breast cancer patients who underwent immediate breast reconstruction (IBR) using the latissimus dorsi myocutaneous flap with/without implants. The demographic characteristics, clinical application feasibility, and the satisfaction rates of the patients were retrospectively collected and evaluated.A total of 43 breast cancer patients who underwent mastectomy between August 2015 and February 2020 were included in the retrospective study. The included patients were subjected to IBR using latissimus dorsi muscular flap (LDMF) with/without implants. The clinical application feasibility and the satisfaction rates of the patients were evaluated.Among these patients, 35 patients underwent nipple-sparing mastectomy and 8 patients underwent skin-sparing mastectomy. Twenty-nine patients underwent IBR using LDMF with implants, and 14 patients underwent IBR using LDMF without implants. Among these patients, 2 patients had partial LDMF necrosis and atrophy, and showed significant shrink of the reconstructed breast. One patient developed seromas, and seromas were improved by active dressing change and sucking out the fluid via the skin using a syringe. Two patients had local skin flap necrosis on the chest, 1 patient had preserved areola and local necrosis of the nipple, and this was healed after dressing change. Based on the Harris method, 27, 9, 5, and 2 cases were evaluated as "excellent," "good," "fair," and "poor," respectively.In the present study, the reconstructed breast has natural shape, good symmetry, and hidden postoperative scars. The aesthetic effect is relatively good, and the use of LDMF may represent an acceptable and valid option for IBR. The success of this procedure depends on the design of the incision, the skill and proficiency of the operation, as well as the correct treatment after surgery.

Prophylactic amifostine prevents a pathologic vascular response in a murine model of expander-based breast reconstruction

BACKGROUND

Although expander-based breast reconstruction is the most commonly used method of reconstruction worldwide, it continues to be plagued with complication rates as high as 60% when radiotherapy is implemented. We hypothesized that quantitative measures of radiotherapy-induced vascular injury can be mitigated by utilizing amifostine in a murine model of expander-based breast reconstruction.

METHODS

30 rats were divided into three groups: expander placement (Control), expander placement followed by radiotherapy (XRT), and expander placement followed by radiotherapy with amifostine (AMF/XRT). All groups underwent placement of a sub-latissimus tissue expander. After a 45 day recovery period, all groups underwent vascular perfusion and micro-CT analysis.

RESULTS

Micro-CT analysis was used to calculate vessel volume fraction (VVF), vessel number (VN), and vessel separation (VSp). A significant increase in VN was seen in the XRT group as compared to the Control (p = 0.021) and the AMF/XRT (p = 0.027). There was no difference between Control and AMF/XRT (p = 0.862). VVF was significantly higher in XRT than either Control (p = 0.043) and AMF/XRT (p = 0.040), however no difference was seen between Control and AMF/XRT (p = 0.980). VSp of XRT was smaller when compared to both Control and AMF/XRT specimens (p = 0.05 and p = 0.048, respectively), and no difference was seen between Control and AMF/XRT (p = 0.339).

CONCLUSIONS

Amifostine administered prior to radiotherapy preserved vascular metrics similar to those of non-radiated specimens. Elevated vascularity demonstrated within the XRT group was not seen in either the Control or AMF/XRT groups. These results indicate that amifostine protects soft tissue in our model from a radiotherapy-induced pathologic vascular response.

Skin-reducing mastectomy and immediate breast reconstruction in patients with macromastia

INTRODUCTION

In women with macromastia, a type IV skin sparing mastectomy is often required to achieve an aesthetically pleasing reconstruction. The introduction of "skin-reducing mastectomy", which inserts a permanent prosthetic device into a large pouch made by the pectoralis major muscle and an inferior pedicle dermal flap, allows the surgeon to achieve a safe oncologic result plus a cosmetically satisfying reconstruction.

OBJECTIVE

We report here our experience with the skin-reducing mastectomy with the aim of emphasizing the problems associated with the technique.

MATERIALS AND METHOD

A study was conduced from April 2009 to November 2012, 74 patients with breast cancer were selected then received a skin-reducing mastectomy. The enrolled women satisfied the criteria of Nava. Statistical analysis was conduced to estimate the significance of the outcome results and complication rate.

RESULT

A total of 88 SRMs were performed and the outcomes were as follows: excellent in 34 patients, good in 21, and poor in 8. We recorded 25 % of adverse events and statistic helped us to identify patient related factors whose can increase the complications onset.

CONCLUSION

Skin-reducing mastectomy is an indispensable procedure to treat cancer in large and pendulous breasts. The correct patient selection is mandatory to reduce the not negligible complication risk. Skin reducing mastectomy when is well conduced allow to obtain good results with patient satisfaction but, like other breast-conserving surgeries, in some case is not the ultimate solution, because it may require some revisions to maintain the optimum results. To day it be consider relatively safe in selected patient and the gold standard in macormastia immediate reconstruction.

Histopathological comparisons of irradiated and non-irradiated breast skin from the same individuals

Because of increasing indications for post-mastectomy irradiation and a growing demand for breast reconstruction using expanders and implants, both these procedures are performed in increasing numbers of patients. Although it is known that irradiation increases the difficulty of subsequent breast reconstruction, there is still insufficient information regarding differences in radiation-induced histopathological changes between individuals. In this study, we had the opportunity to take skin biopsy specimens from both the irradiated and non-irradiated breasts of 20 patients, and examine the histopathological differences between them. Skin was taken from the irradiated breast of 20 patients at the time of breast reconstruction, and skin was taken from the contralateral non-irradiated breast at the time of contralateral reconstruction, reduction or implant insertion for augmentation. A horizontally oriented specimen of skin was taken from both sides. Specimens were horizontally sliced and histopathologically examined by light microscopy and scanning electron microscopy (SEM). We identified five characteristic histological changes in the irradiated breast skin: (1) hyperplasia of the epidermis; (2) flattening of the papillary layer; (3) atrophy of dermal appendages; (4) high density of dermal collagen fibres; and (5) unidirectional alignment of the dermal collagen fibres (UACF). UACF was further confirmed by SEM. UACF seemed to be strongly associated with complications. These histopathological findings correlated with the difficulty of expanding irradiated skin, resulting in poor aesthetic outcomes such as capsular contracture and expander/implant extrusion. Careful attention should be paid to the techniques of breast reconstruction after irradiation.

An exploration of patient decision-making for autologous breast reconstructive surgery following a mastectomy

OBJECTIVE

The aim of this study was to examine patients' experiences of the decision to undergo breast reconstructive surgery following mastectomy.

METHOD

21 Women, who had undergone reconstruction, took part in a semi-structured qualitative interview, which examined the participants' experience of the decision-making process. The recorded interviews were transcribed verbatim and analyzed using "framework analysis".

RESULTS

Women who underwent immediate reconstruction spoke of the convenience of undergoing only one operation with regards to juggling work and childcare arrangements. For women who underwent delayed reconstructive surgery the reasons centre on dissatisfaction with wearing prosthesis. Others spoke of no choice, as immediate reconstruction was not offered as an option. However both groups did report similar influential factors and received and used similar informational content and informational sources in order to make their decision.

CONCLUSION

The study outlines the different motivations for undergoing immediate or delayed breast reconstruction and highlights that there is not always a choice offered to patients.

PRACTICE IMPLICATIONS

Future patients who are considering breast reconstruction should be provided with the relevant information to make a well informed decision and may benefit from different methods of information delivery that could include decision aids such as informational booklets, photographs, and videos.

Single-stage immediate breast reconstruction using a skin-sparing incision and definitive saline implants compared with a two-stage reconstruction using tissue expansion plus implants

BACKGROUND

Losing a breast to cancer has significant psychological ramifications, and it has been shown that minimizing this loss can have a profound impact. As a result, breast-conserving therapy or mastectomy followed by breast reconstruction have become the preferred surgical treatments for breast cancer. Limited available breast skin following mastectomy has traditionally necessitated the use of autologous tissue or tissue expansion; however, when reconstructing larger breasts, autologous tissue grafts rarely provide enough tissue and tissue expanders can often take several months to achieve the necessary tissue volume. The skin-sparing mastectomy offers a solution to this lack of skin, and as a result many new options for immediate breast reconstruction have presented. The present pilot study looks at a new method of immediate breast reconstruction involving a Wise pattern skin-sparing mastectomy with placement of a definitive, submuscular saline implant as a way to maintain a large breast size without requiring the patient to undergo a long and painful tissue expansion process.

METHODS

A retrospective, case-control study was performed on 12 women who had undergone bilateral mastectomies with immediate reconstruction either with a tissue expander and later placement of definitive saline implant (control group) (n=5) or who had undergone a single-stage reconstruction involving the placement of a definitive submuscular saline implant (experimental group) (n=7). Patients were compared with respect to change in breast size, number of reoperations and operations in total, as well as satisfaction with their reconstruction.

RESULTS

Patient satisfaction in both groups was relatively high and there was no statistically significant difference found between the two groups. The experimental group decreased in bra size by 1.4 cup sizes on average whereas the control group experienced no change on average; however, one-third of patient data had to be discarded for various reasons, making the change in size measurement inconclusive. Finally, the average number of reoperations was higher in the experimental group than the control (1.57 versus 1.00); however, the total number of operations required was less (2.57 versus 2.80).

CONCLUSIONS

Immediate breast reconstruction using a definitive submuscular saline implant is a viable option for reconstruction in women with larger breasts that deserves further study on a larger scale. Although limited by sample size, the present pilot study showed, with a large effect size, that this new procedure reduces the total number of operations required for reconstruction when compared with a tissue expander followed by an implant while maintaining an equally high level of patient satisfaction.
