Impact of Adjuvant Radiotherapy on Free Flap Volume in Autologous Breast Reconstruction: A Scoping Review. J Clin Med 2023; 13:217. [PMID: 38202224 PMCID: PMC10779607 DOI: 10.3390/jcm13010217] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Revised: 12/21/2023] [Accepted: 12/26/2023] [Indexed: 01/12/2024] Open
Abstract
In autologous breast reconstruction, a sufficient flap volume is fundamental to restore breast shape and ensure an aesthetic outcome. After mastectomy, postoperative irradiation is regularly indicated in the oncological treatment algorithm. When administering radiation therapy after autologous reconstruction, the tissue transferred is inherently irradiated. Although there is evidence that points to a reduction in flap volume after adjuvant radiotherapy, the data have been contradicting and inconclusive. To address this anecdotal evidence, we performed a scoping review of the current literature that addresses the effect of radiotherapy on breast flap volume. Six two-armed studies, comprising a total of 462 patients, reported on the effect of adjuvant radiotherapy on free flap volume changes. Of those, two studies found a significant negative impact of radiotherapy on free flap volume, while the other four studies did not. Reported flap volume changes ranged from no change to a reduction of 26.2%, measured up to two years postoperatively. The selected studies contain varying patient numbers, follow-up timepoints, types of flaps, and measuring methods, contributing to a relatively high heterogeneity. While we present some evidence suggesting a significant impact of adjuvant radiotherapy on breast flap volume, future studies are needed to further investigate this potential correlation.

Abstract
Due to refinements in operating techniques, autologous breast reconstruction has become part of standard care. It has become more difficult to advise patients due to the expansion of oncologic options for mastectomy, radiation therapy and the variety of reconstructive techniques. The goal of reconstruction is to achieve oncologically clear margins and a long-term aesthetically satisfactory result with a high quality of life. Immediate reconstruction preserves the skin of the breast and its natural form and prevents the psychological trauma associated with mastectomy. However, secondary reconstructions often have a higher satisfaction, since here no restitutio ad integrum is assumed. Alloplastic, i. e., implant-based, breast reconstruction and autologous breast reconstruction are complementary techniques. This article provides an overview of current options for breast reconstruction including patients' satisfaction and quality of life following breast reconstruction. Although immediate reconstruction is still the preferred choice of most patients and surgeons, delayed reconstruction does not appear to compromise clinical or patient-reported outcomes. Recent refinements in surgical techniques and autologous breast reconstruction include stacked-flaps, as well as microsurgical nerve coaptation to restore sensitivity, which lead to improved outcomes and quality of life. Nowadays Skin-sparing and nipple-sparing mastectomy, accompanied by improved implant quality, allows immediate prosthetic breast reconstruction as well as reemergence of the prepectoral implantation. The choice of breast reconstruction depends on the type of mastectomy, necessary radiation, individual risk factors, as well as the patient's habitus and wishes. Overall, recent developments in breast reconstruction led to an increase in patient satisfaction, quality of life and aesthetic outcome with oncological safety.

Radiotherapy-induced oxidative stress and fibrosis in breast cancer are suppressed by vactosertib, a novel, orally bioavailable TGF-β/ALK5 inhibitor. Sci Rep 2022; 12:16104. [PMID: 36167880 PMCID: PMC9515166 DOI: 10.1038/s41598-022-20050-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Accepted: 09/08/2022] [Indexed: 11/16/2022] Open
Abstract
Radio-resistance resulting from radiotherapy-induced fibrosis is a major clinical obstacle in breast cancer treatment because it typically leads to cancer recurrence, treatment failure, and patient death. Transforming growth factor-β (TGF-β) is a key signal messenger in fibrosis, which plays an important role in radiation-induced fibrosis and cancer stem cell (CSC) development, may be mediated through the generation of oxidative stress. This study was conducted to confirm the efficacy of vactosertib, a TGF-β/ALK5 inhibitor, as a potent inhibitor in radiation-induced oxidative stress generation, fibrosis and CSC development. We used a 4T1-Luc allograft BALB/c syngeneic mouse model and 4T1-Luc and MDA-MB-231 cells for histological analysis, qRT-PCR, western blotting, ROS analysis, mammosphere formation analysis, monolayer fluorescence imaging analysis. Radiotherapy induces TGF-β signaling, oxidative stress markers (4-HNE, NOX2, NOX4, PRDX1, NRF2, HO-1, NQO-1), fibrosis markers (PAI-1, α-SMA, FIBRONECTIN, COL1A1), and CSC properties. However, combination therapy with vactosertib not only inhibits these radiation-induced markers and properties by blocking TGF-β signaling, but also enhances the anticancer effect of radiation by reducing the volume of breast cancer. Therefore, these data suggest that vactosertib can effectively reduce radiation fibrosis and resistance in breast cancer treatment by inhibiting radiation-induced TGF-β signaling and oxidative stress, fibrosis, and CSC.

Abstract
Oncoplastic breast surgery encompasses a range of techniques used to provide equitable oncological outcomes compared with standard breast surgery while, simultaneously, prioritizing aesthetic outcomes. While the outcomes of oncoplastic breast surgery are promising, it can add an extra complexity to the treatment paradigm of breast cancer and impact on decision-making surrounding adjuvant therapies, like chemotherapy and radiotherapy. As such, early discussions at the multidisciplinary team meeting with surgeons, medical oncologists, and radiation oncologists present, should be encouraged to facilitate best patient care.

J Plast Reconstr Aesthet Surg 2022; 75:2561-2568. [PMID: 35370117 DOI: 10.1016/j.bjps.2022.02.072] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2021] [Revised: 01/17/2022] [Accepted: 02/22/2022] [Indexed: 11/15/2022]
Abstract
Implant malposition has been reported to be a common reason for revision surgery after implant-based breast reconstruction (IBR). With the recent increase in the use of smooth implants due to concerns for breast implant-associated anaplastic large-cell lymphoma with textured implants, we compared and reported the rates of malposition in prepectoral IBR and identified risk factors. A retrospective review of patients who underwent prepectoral IBR with Natrelle® (Allergan, Inc., Irvine, CA) implants at our institution between January 2014 and May 2020 was performed. Clinical characteristics, implant types, and the rate of malposition, defined as implant flipping or rotation, were recorded. Univariate and multivariable time-to-event analyses using the Cox proportional-hazards model were performed to identify predictors of malposition. Three hundred seventy-five patients (660 breasts) were included. Four hundred forty-one (66.8%) breasts had smooth round implants whereas 219 (33.2%) had textured anatomical devices. Malposition requiring either a manual correction or surgical intervention occurred in 26 (5.9%) smooth round implants versus 3 (1.4%) textured anatomical. Multivariable analysis showed that having a smooth round implant (aHR: 7.19, 95% CI: [2.04 - 25.4]) and an increase in implant volume (aHR: 1.003, 95% CI: [1.001 - 1.006]) were associated with having a malposition requiring intervention. Among smooth round implants; INSPIRA® Cohesive implants were more likely to result in a malposition requiring intervention (p<0.0001) compared to other smooth round implants. Overall, malposition requiring intervention occurred in 5.9% of smooth round implants and 1.4% of textured anatomical implants. Statistical analysis demonstrates that smooth round implants and an increase in implant volume both are associated with a malposition requiring intervention.

Does post-mastectomy radiation therapy worsen outcomes in immediate autologous breast flap reconstruction? A systematic review and meta-analysis. J Plast Reconstr Aesthet Surg 2021; 74:3260-3280.

Abstract
BACKGROUND There is great uncertainty regarding the practice of immediate autologous breast reconstruction (IBR) when post-mastectomy radiotherapy (PMRT) is indicated. Plastic surgery units differ in their treatment protocols, with some recommending delayed breast reconstruction (DBR) following PMRT. IBR offers significant cosmetic and psychosocial benefits; however, the morbidity of flap exposure to radiation remains unclear. OBJECTIVE The aim of this review was to comprehensively analyze the existing literature comparing autologous flaps exposed to PMRT and flaps with no radiation exposure. METHODS A comprehensive search in MEDLINE, EMBASE and CENTRAL databases was conducted in November 2020. Primary studies comparing IBR with and without adjuvant PMRT were assessed for the following primary outcomes: clinical complications, observer-reported outcomes and patient-reported satisfaction rates. Meta-analysis was performed to obtain pooled risk ratios of individual complications. RESULTS Twenty-one articles involving 3817 patients were included. Meta-analysis of pooled data gave risk ratios for fat necrosis (RR = 1.91, p < 0.00001), secondary surgery (RR = 1.62, p = 0.03) and volume loss (RR = 8.16, p < 0.00001) favoring unirradiated flaps, but no significant difference was observed in all other reported complications. The no-PMRT group scored significantly higher in observer-reported measures. However, self-reported aesthetic and general satisfaction rates were similar between groups. CONCLUSION IBR should be offered after mastectomy to patients requiring PMRT. The higher risks of fat necrosis and contracture appear to be less clinically relevant as corroborated by positive scores from patients developing these complications. Preoperative and intraoperative measures should be taken to further optimize reconstruction and mitigate post-radiation sequel. Careful management of patients' expectations is also imperative. LEVEL OF EVIDENCE Level III.

Abstract
Radiation therapy is a valuable tool in the treatment of numerous malignancies but, in certain cases, can also causes significant acute and chronic damage to noncancerous neighboring tissues. This review focuses on the pathophysiology of radiation-induced damage and the clinical implications it has for plastic surgeons across breast reconstruction, osteoradionecrosis, radiation-induced skin cancers, and wound healing. The current understanding of treatment modalities presented here include hyperbaric oxygen therapy, autologous fat grafting and stem cells, and pharmaceutical agents.

Abstract
PURPOSE This study investigated whether hypofractionated adjuvant radiotherapy (RT) increased breast-related complication(s) compared to conventional fractionated RT in reconstructed breast cancer patients. METHODS We conducted a retrospective review including 349 breast cancer patients who underwent immediate breast reconstruction following mastectomy or breast-conserving surgery (BCS) between 2009 and 2018 at two institutions. All patients were treated with adjuvant RT via either a conventional fractionated or hypofractionated regimen. We defined a major breast complication as a breast-related toxic event requiring re-operation or re-hospitalization during the follow-up period after the end of RT. RESULTS The median follow-up was 32.3 months (4.8-118.5 months); 126 patients had conventional fractionated RT, and 223 patients received hypofractionated RT. In patients with mastectomy, there was no significant difference in the occurrence of any or major breast-related complications between the two fractionation regimens. In patients undergoing BCS, incidence of any breast complication showed no difference between two RT groups and no major breast complication was reported as well. Hypofractionated RT did not increase major wound problem (infection and dehiscence) compared to conventional RT. Incidence of major contracture was significantly lower in hypofractionated RT. CONCLUSIONS There was no significant difference in the occurrence of any or major breast-related complications between the two different fractionation regimens, even in patients with mastectomy. Hypofractionated RT may be used comparable to conventional fractionated RT in terms of breast-related complications in reconstructed breast cancer patients. The prospective randomized trial would be necessary to clarify this issue.

Abstract
Radiotherapy (RT) has become an indispensable part of oncologic treatment protocols for a range of malignancies. However, a serious adverse effect of RT is radiodermatitis; almost 95% of patients develop moderate to severe skin reactions following radiation treatment. In the acute setting, these can be erythema, desquamation, ulceration, and pain. Chronically, soft tissue atrophy, alopecia, and stiffness can be noted. Radiodermatitis can delay oncologic treatment protocols and significantly impair quality of life. There is currently a paucity of effective treatment options and prevention strategies for radiodermatitis. Importantly, recent preclinical and clinical studies have suggested that fat grafting may be of therapeutic benefit, reversing detrimental changes to soft tissue following RT. This review outlines the damaging effects of RT on the skin and soft tissue as well as discusses available treatment options for radiodermatitis. Emerging strategies to mitigate detrimental, chronic radiation-induced changes are also presented.

Abstract
Postmastectomy radiotherapy (PMRT) following immediate breast reconstruction is increasingly adopted in the management of breast cancer patients. We retrospectively evaluate the complication rates of PMRT using VMAT technique to immediate tissue expander-based reconstructions and the possible impact of tissue expander volume on radiotherapy planning. We reviewed the data of patients who underwent immediate expander breast reconstruction and received PMRT with VMAT (50 Gy in 25 fractions) on the reconstructed breast and axillary levels III-IV. Neoadjuvant or adjuvant systemic therapy was administered in most of the patients. Autologous fat grafting was routinely performed at the time of second-stage reconstruction. Between 2015 and 2017, PMRT was delivered to 46 consecutive patients (median age 50 years) with expander reconstruction. Median follow-up was 27 months (range 10-41). Two patients (4.3%) had a reconstruction failure, as expander rupture and infection, following the first- and the second-stage reconstruction, respectively. In most cases expanders were completely inflated before PMRT (65.2%). Median expander volume before PMRT was 425 cm3 (range 150-700 cm3). The amount of expander inflation did not significantly affect dosimetry, except for skin dose, with a surface receiving more than 30 Gy of 36.6 ± 0.9 cm2 and 47.0 ± 2.5 cm2 for a volume expander below or above the median, respectively. However, this variable was not predictor for complications. Disease progression was recorded in 15.2% of patients. PMRT using VMAT technique for breast cancer patients with expander reconstruction is associated with a very low complication rate. The expander volume before PMRT does not significantly compromise radiotherapy dose distribution.

Abstract
PURPOSE There is an ongoing debate on the optimal sequence of radiation and breast reconstruction. The purpose of this article was to (a) assess the impact of radiation on autologous breast reconstruction and (b) analyze the best timing for autologous breast reconstruction in the setting of radiation in a Chinese population. METHODS A retrospective review of patients undergoing breast reconstruction with autologous lower abdominal flaps between 2001 and 2014 in the Tianjin Medical University and Cancer Hospital was performed. Patients were grouped by their irradiation status (irradiated vs nonirradiated). The irradiated group was further stratified into 2 groups by the timing of irradiation (immediate breast reconstruction followed by radiation vs prior radiation and delayed breast reconstruction). The primary outcomes were early and late breast complications, secondary and revision surgeries to the reconstructed breast, whereas the secondary outcomes were aesthetic and psychological evaluations of the patients. Logistic regression was used to assess the potential association between irradiation, patient and treatment variables, and surgical outcomes. RESULTS Three hundred sixty patients with 370 reconstructed breasts were included in the study. Two hundred seventy-eight cases were nonirradiated, of which 158 were immediate and 120 were delayed. Ninety-two cases were irradiated, of which 61 were immediate, and 31 were delayed. Three hundred thirty-two cases underwent pedicled transverse rectus abdominis myocutaneous flap, 38 had deep inferior epigastric perforator flap. The irradiated group had a significant increase in secondary surgery due to fat necrosis (P < 0.001) and in late complications (P = 0.011). A significant increase in flap contracture (P = 0.043) and an increasing trend in the severity of fat necrosis were observed when radiation was performed after breast reconstruction. However, radiation and its timing did not have an adverse impact on patients' aesthetic and psychological evaluations by the Breast-Q survey. CONCLUSIONS Radiation administered to the reconstructed breast mound increased the rate of late complications and the need for secondary surgery with increased abdominal flap shrinkage and contracture and the severity of flap fat necrosis. Irradiation on the reconstructed breast did not lead to worse aesthetic outcomes due to the generally different expectation in the Chinese female patients in that they were more focused on the breast shape when clothed. Immediate breast reconstruction followed by irradiated was a generally successful treatment sequence in the Chinese module.

The Impact of Expander Inflation/Deflation Status During Adjuvant Radiotherapy on the Complications of Immediate Two-Stage Breast Reconstruction. Aesthetic Plast Surg 2017; 41:551-559. [PMID: 28374300 DOI: 10.1007/s00266-017-0864-5] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2017] [Accepted: 03/19/2017] [Indexed: 10/19/2022]
Abstract
BACKGROUND The question of whether expander inflation/deflation status has any bearing on surgical complications in the setting of adjuvant radiation (XRT) has not been addressed. The objective of this study is to investigate whether the inflation/deflation status of the expander at the time of XRT is associated with complications in immediate two-stage expander-implant breast reconstruction. METHODS A retrospective review of 49 consecutive patients who underwent immediate two-stage expander-implant breast reconstruction and received post-mastectomy XRT was conducted. Full deflation of the expanders was performed in the deflation group (20 patients), while the expanders remained inflated in the inflation group at the time of XRT (29 patients). XRT-related complications of each stage of reconstructions were compared between the two groups, and multivariable regression analysis was performed to identify risk factors for XRT-related complications. RESULTS Overall XRT-related complications (65.0 vs. 6.9%, p < 0.001) and reconstruction failures (35.0 vs. 6.9%, p = 0.022) of the first-stage reconstructions were significantly higher in the deflation group. The most common cause of reconstruction failure in the deflation group was failure to re-expand due to skin fibrosis and contracture. In multivariable analysis, deflation of expanders was a significant risk factor for overall complications (odds = 94.4, p = 0.001) and reconstruction failures (odds = 9.09, p = 0.022) of the first-stage reconstructions. CONCLUSIONS Maximal inflation without deflation before XRT can be an option to minimize XRT-related complications and reconstruction failure of the first-stage reconstructions.

Neoadjuvant radiotherapy followed by mastectomy and immediate breast reconstruction : An alternative treatment option for locally advanced breast cancer. Strahlenther Onkol 2017; 193:324-331.

Abstract
BACKGROUND The optimal sequence of mastectomy with immediate breast reconstruction (IBR) and radiotherapy (RT) for the treatment of locally advanced breast cancer (LABC) is still under debate. Increased rates of postoperative complications are described following postmastectomy RT. Neoadjuvant RT aims to improve the aesthetic results and simplify the reconstructive pathway. PATIENTS A total of 22 patients diagnosed with LABC and treated with neoadjuvant RT followed by mastectomy and IBR between 04/2012 and 03/2015 were retrospectively analyzed. RT consisted of external beam RT to the breast and the regional lymphatics, if indicated. Both implant-based and autologous tissue-transfer reconstruction techniques were used. RESULTS At the time of RT, 10 patients had no prior surgery and 12 patients had previously undergone breast-conserving surgery (BCS) with positive resection margins without the possibility to perform a second BCS. Additional neoadjuvant chemotherapy was administered in 18 patients prior to RT. A complete pathological response was achieved in 55.0% of patients. The 2‑year overall survival rate was 89.3%, the 2‑year disease-free-survival 79.8% and the local-recurrence-free survival was 95.2%. The cosmetic result was excellent or good in 66% of the patients treated with upfront mastectomy and 37% of the patients who had previously undergone BCS. Among patients who received implant-based IBR, 4 patients developed serious wound-healing problems with implant loss. The most satisfactory results were achieved with autologous tissue reconstruction. CONCLUSION A sequential neoadjuvant chemo-/radiotherapy to allow IBR following mastectomy in selected cases of LABC seems feasible and can be safely attempted. Careful patient selection, close monitoring, and continuous patient support is mandatory to ensure compliance in this treatment strategy.

Fewer Revisions in Abdominal-based Free Flaps than Latissimus Dorsi Breast Reconstruction after Radiation. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2016; 4:e866.

Abstract
The most commonly chosen flaps for delayed breast reconstruction after postmastectomy radiation therapy (PMRT) are abdominal-based free flaps (ABFFs) and pedicled latissimus dorsi (LD) musculocutaneous flaps. The short-and long-term advantages and disadvantages of delayed ABFFs versus LD flaps after PMRT remain unclear. We hypothesized that after PMRT, ABFFs would result in fewer postoperative complications and a lower incidence of revision surgery than LD flaps.

Abstract
INTRODUCTION Therapeutic mammoplasty is used in the treatment of suitably-sized and appropriately-located breast cancers to achieve adequate cancer excision, resulting in well-shaped but smaller breasts. In patients wishing to maintain or increase their breast size, simultaneous augmentation will be required. PRESENTATION OF CASE A 48-year-old female underwent an "augmentation-therapeutic mastopexy". She required mastectomy for a multifocal cancer of the right breast and breast conservation for a unifocal localised cancer in the upper part of the left breast. She requested right immediate breast reconstruction and hoped for larger breasts than she had. Due to complications during neoadjuvant chemotherapy, the right reconstruction plan was changed from a deep inferior epigastric perforator (DIEP) flap to an implant-based technique. On the left, an extended superomedial pedicle therapeutic mammoplasty was combined with a subpectoral augmentation using an expandable-implant. DISCUSSION The use of expandable-implants for reconstruction of partial mastectomy defects in combination with therapeutic mammoplasty has not been reported. This case report shows that such "augmentation-therapeutic mastopexy" is feasible. CONCLUSION A "novel" oncoplastic technique herein termed "augmentation-therapeutic mastopexy" is described for partial breast reconstruction during the treatment of a patient with bilateral breast cancer. It enabled adequate treatment of her cancer while reshaping the breast and achieving the desired larger breast size. It should be considered in selected breast-conservation patients who wish to maintain or increase their breast size.

Abstract
Conventional volumetric modulated arc therapy (C-VMAT) for breast cancer after radical mastectomy had its limitation that resulted in larger volumes of normal tissue receiving low doses. We explored whether there was a way to deal with this disadvantage and determined the potential benefit of flattening filter-free (FFF) beams.Twenty patients with breast cancer after radical mastectomy were subjected to 3D conformal radiotherapy (3DCRT) and VMAT treatment planning. For VMAT plans, 3 different designs were employed with RapidArc form: conventional-VMAT plan (C-VMAT), modified-VMAT plan (M-VMAT), and modified-VMAT plan using FFF beams (M-VMAT-F). Plan quality and efficiency were assessed for all plans.For each technique in homogeneity, there were no statistically significant differences. VMAT plans showed superiority compared with 3DCRT in conformity. C-VMAT plans were obviously not only superior to 3DCRT in the medium to high-dose regions (about 15-50 Gy) but also resulted in larger volumes in low-dose regions (about 0-10 Gy). M-VMAT plans were similar to M-VMAT-F. Both of them might significantly reduce the regions of low dose compared with C-VMAT (V5lung: ∼ 11.5%; V5heart: ∼ 23.8%, P < 0.05), even less than 3DCRT in heart irradiation (V2.5heart, 9.4%, P < 0.05). For liver, contralateral breast, and lung irradiation, M-VMAT-F plans were slightly superior to M-VMAT with a reduction of ∼0.08, 0.2, and 0.24 Gy in the respective mean doses (P < 0.05).C-VMAT plans showed superiority compared with 3DCRT, while also resulted in larger volumes of normal tissue receiving low doses. M-VMAT and M-VMAT-F plans might not only reduce the region in the medium to high doses but also have lower volumes in low-dose regions. M-VMAT-F plans were slightly superior compared with M-VMAT due to further contralateral organs sparing.

Abstract
Introduction: Impaired vascular perfusion in tissue expander (TE) breast reconstruction leads to mastectomy skin necrosis. We investigated factors and costs associated with skin necrosis in postmastectomy breast reconstruction. Methods: Retrospective review of 169 women with immediate TE placement following mastectomy between May 1, 2009 and May 31, 2013 was performed. Patient demographics, comorbidities, intraoperative, and postoperative outcomes were collected. Logistic regression analysis on individual variables was performed to determine the effects of tissue expander fill volume and mastectomy specimen weight on skin necrosis. Billing data was obtained to determine the financial burden associated with necrosis. Results: This study included 253 breast reconstructions with immediate TE placement from 169 women. Skin necrosis occurred in 20 flaps for 15 patients (8.9%). Patients with hypertension had 8 times higher odds of skin necrosis [odd ratio (OR), 8.10, P < 0.001]. Patients with TE intraoperative fill volumes >300 cm3 had 10 times higher odds of skin necrosis (OR, 10.66, P =0.010). Volumes >400 cm3 had 15 times higher odds of skin necrosis (OR, 15.56, P = 0.002). Mastectomy specimen weight was correlated with skin necrosis. Specimens >500 g had 10 times higher odds of necrosis and specimens >1000 g had 18 times higher odds of necrosis (OR, 10.03 and OR, 18.43; P =0.003 and P <0.001, respectively). Mastectomy skin necrosis was associated with a 50% increased inpatient charge. Conclusion: Mastectomy flap necrosis is associated with HTN, larger TE volumes and mastectomy specimen weights, resulting in increased inpatient charges. Conservative TE volumes should be considered for patients with hypertension and larger mastectomy specimens.

Abstract
BACKGROUND Postmastectomy radiation therapy (PMRT) has a well-established deleterious effect on both prosthetic and autologous breast reconstruction. The purpose of this study was to perform a literature review of the effects of PMRT on breast reconstruction and to determine predictive or protective factors for complications. METHODS The MEDLINE and EMBASE databases were reviewed for articles published between January 2008 and January 2015 including the keywords "breast reconstruction" and "radiation therapy" to identify manuscripts focused on the effects of radiation on both prosthetic and autologous breast reconstruction. This subgroup of articles was reviewed in detail. RESULTS Three hundred and twenty articles were identified and 43 papers underwent full text review. The 16 papers provided level III evidence; 10 manuscripts provided level I or II evidence. Seventeen case series provided level IV evidence and were included because they presented novel perspectives. The majority of studies focused on the injurious effects of radiation therapy and increased complications and concomitant lower patient satisfaction. CONCLUSIONS Prosthetic based breast reconstruction and immediate autologous reconstruction are associated with lower patient satisfaction in the setting of radiation therapy. Autologous reconstructions can improve patient satisfaction as well as lower revision surgery and long term complications when performed in a delayed fashion after PMRT.

Abstract
BACKGROUND Irradiation to free flaps following immediate breast reconstruction has been shown to compromise outcomes. The authors hypothesized that irradiated muscle-sparing free transverse rectus abdominis musculocutaneous (TRAM) flaps experience less fat necrosis than irradiated deep inferior epigastric perforator (DIEP) flaps. METHODS The authors performed a retrospective study of all consecutive patients undergoing immediate, autologous, abdomen-based free flap breast reconstruction with muscle-sparing free TRAM or DIEP flaps over a 10-year period at their institution. Irradiated flaps (external-beam radiation therapy) after immediate breast reconstruction were compared with nonirradiated flaps. Logistic regression analysis identified potential associations between patient, tumor, and reconstructive characteristics and surgical outcomes. RESULTS The analysis included 625 flaps: 40 (6.4 percent) irradiated versus 585 (93.6 percent) nonirradiated. Mean follow-up for the irradiated and nonirradiated flaps was 60.0 and 48.5 months, respectively (p = 0.02). Overall complication rates were similar for both the irradiated and nonirradiated flaps. Irradiated flaps (i.e., both DIEP and muscle-sparing free TRAM flaps) developed fat necrosis at a significantly higher rate (22.5 percent) than the nonirradiated flaps (9.2 percent; p = 0.009). There were no differences in fat necrosis rates between the DIEP and muscle-sparing free TRAM flaps in both the irradiated and nonirradiated groups. CONCLUSIONS Both DIEP and muscle-sparing free TRAM flap reconstructions had much higher rates of fat necrosis when irradiated. Contrary to our hypothesis, the authors found that immediate breast reconstruction with a muscle-sparing free TRAM flap does not result in a lower rate of fat necrosis than reconstruction with a DIEP flap.

Abstract
BACKGROUND The potential ramifications of radiation use can be of particular concern in the breast reconstruction population, in which both surgical and aesthetic outcomes are important. Presently, there remains a paucity of data detailing the influence of radiation on specific reconstruction aesthetic outcomes. OBJECTIVE To conduct a quantitative evaluation of aesthetic outcomes for expander-implant breast reconstruction in radiated and nonradiated patients using a validated scoring scale. METHODS A series of consecutive expander-implant breast reconstruction operations performed by the senior author between 2004 and 2012 were reviewed. Four blinded members of the Division of Plastic and Reconstructive Surgery at Northwestern University (Illinois, USA) independently rated postoperative photographs of patients' breasts using a validated scoring scale with respect to five distinct aesthetic domains. RESULTS Of the 206 patients meeting the inclusion criteria, 69 received radiotherapy and 137 did not. The radiated cohort had lower scores in each aesthetic domain, with significant differences in contour (1.33 versus 1.51; P=0.041) and placement (1.45 versus 1.73; P<0.001). Linear regression analysis revealed a significant association between placement scores and radiation, and radiated patients had a significantly higher overall rate of complications. DISCUSSION Variances in scores may represent the relative difficulty of expansions and proper implant placement in irradiated tissue, with possible skin fibrosis and decreased flexibility hindering prosthesis manipulation. CONCLUSION Radiation adversely impacts breast contour and placement, with possible negative contributions to volume, scarring and inframammary fold definition, and results in higher rates of complications. Such detailed evaluation of the impact of radiation on aesthetics will enhance the management of patient expectations.

Abstract
BACKGROUND Increasing numbers of patients with breast cancer are being treated with postmastectomy radiation therapy. The author reviewed the literature to determine the clinical impact of this increasing use of postmastectomy radiation therapy in patients with breast cancer who desire implant-based breast reconstruction. METHODS The author searched the MEDLINE database for articles on breast reconstruction and radiation therapy published between January of 2008 and June of 2011 and reviewed the abstracts of those articles to identify articles with information about the impact of irradiation on implant-based breast reconstruction. This subgroup of articles was reviewed in detail. RESULTS Two hundred eighty-five articles were identified. Nineteen articles were reviewed in detail. Eight articles provided level III evidence; one provided level I or II evidence from high-quality multicenter or single-center randomized controlled trials or prospective cohort studies. Two articles provided level IV evidence from case series and were included in the review because they offered a novel approach or perspective. The most recent studies find a significant need for unplanned or major corrective surgery in irradiated breasts reconstructed with implants. Although breast implant reconstruction in irradiated breasts is associated with high rates of complications, only a minority of patients require conversion to an autologous tissue flap. CONCLUSION Although the majority of patients who undergo implant-based reconstruction and irradiation ultimately keep the implant reconstruction, patient surveys show that irradiation has a significantly negative effect on patient satisfaction.

Abstract
BACKGROUND The threshold for patients with breast cancer to receive radiation therapy continues to be lowered. The author reviewed the literature to determine the clinical impact that the increasing use of radiation therapy has had on the management of patients with breast cancer who desire autologous tissue-based breast reconstruction. METHODS The MEDLINE database was searched for articles on breast reconstruction and radiation therapy published between January of 2008 and June of 2011. Abstracts of those articles were reviewed to identify articles that addressed the most pressing radiation-related issues facing reconstructive breast surgeons performing autologous tissue-based reconstruction. This subgroup of articles was reviewed in detail. RESULTS Two-hundred eighty-five articles were identified. Seventeen articles were reviewed in detail. Nine articles provided level III evidence, mostly from retrospective comparative studies. Five articles provided level I (n=2) or II (n=3) evidence from high-quality, multicenter or single-center, randomized, controlled trials or prospective cohort studies. Three articles provided level IV evidence from case series and were included in the review because they offered a novel approach or perspective. Since the author's last review of the literature in 2009, there have been changes in the practice patterns in the approach to autologous breast reconstruction in patients who undergo radiation therapy. CONCLUSION With the increasing use of radiation therapy in patients with breast cancer, future studies should seek to provide more meaningful data (level I and II evidence) to help guide clinical decision-making. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.

Abstract
BACKGROUND Breast cancer recurrences in previously irradiated areas are treated with reirradiation (reRT) and hyperthermia (HT). The aim of this retrospective study is to quantify the toxicity of HT in breast cancer patients with reconstruction. METHODS Between 1992 and 2009, 36 patients were treated with reRT with a scheme of 8 fractions of 4.0 Gy in 4 weeks, and HT on a total of 37 tissue reconstructions. The types of reconstructions were: split-thickness skin graft (15), transverse rectus abdominis myocutaneous flap (1), latissimus dorsi flap (14), rhomboid flap (1) or a combination of grafts and flaps (6). Toxicities were graded according to the Common Terminology Criteria for Adverse Events (CTCAE), version 3.0. Patient, tumour, and treatment characteristics predictive for the endpoints were identified in univariate and multivariate analyses. The primary endpoint was HT toxicity. Secondary endpoints were acute and late radiotherapy (RT) toxicity, complete response (CR), local control (LC) and overall survival (OS). RESULTS The median follow-up time was 64 months. Grade 2 HT toxicity occurred in four patients and grade 3 in three. The three patients with grade 3 HT toxicity required reoperation. None of the evaluated parameters showed a significant relationship with HT toxicity. The CR rate in 15 patients with macroscopic disease was 80%. The 3 and 5 year LC rates were 74% and 69%; the median OS was 55 months. CONCLUSIONS Combined reRT and HT in breast cancer patients with reconstruction is safe and effective.

Chest wall radiotherapy with volumetric modulated arcs and the potential role of flattening filter free photon beams. Strahlenther Onkol 2012; 188:484-90. [PMID: 22402870 DOI: 10.1007/s00066-012-0075-6] [Citation(s) in RCA: 32] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2011] [Accepted: 01/11/2012] [Indexed: 01/09/2023]
Abstract
PURPOSE The goal of the work was to assess the role of RapidArc treatments in chest wall irradiation after mastectomy and determine the potential benefit of flattening filter free beams. METHODS AND MATERIAL Planning CT scans of 10 women requiring post-mastectomy chest wall radiotherapy were included in the study. A dose of 50 Gy in 2 Gy fractions was prescribed. Organs at risk (OARs) delineated were heart, lungs, contralateral breast, and spinal cord. Dose-volume metrics were defined to quantify the quality of concurrent treatment plans assessing target coverage and sparing of OARs. Plans were designed for conformal 3D therapy (3DCRT) or for RapidArc with double partial arcs (RA). RapidArc plans were optimized for both conventional beams as well as for unflattened beams (RAF). The goal for this planning effort was to cover 100% of the planning target volume (PTV) with ≥ 90% of the prescribed dose and to minimize the volume inside the PTV receiving > 105% of the dose. The mean ipsilateral lung dose was required to be lower than 15 Gy and V(20 Gy) < 22%. Contralateral organ irradiation was required to be kept as low as possible. RESULTS All techniques met planning objectives for PTV and for lung (3DCRT marginally failed for V(20 Gy)). RA plans showed superiority compared to 3DCRT in the medium to high dose region for the ipsilateral lung. Heart irradiation was minimized by RAF plans with ~4.5 Gy and ~15 Gy reduction in maximum dose compared to RA and 3DCRT, respectively. RAF resulted in superior plans compared to RA with respect to contralateral breast and lung with a reduction of ~1.7 Gy and 1.0 Gy in the respective mean doses. CONCLUSION RapidArc treatment resulted in acceptable plan quality with superior ipsilateral tissue sparing compared to traditional techniques. Flattening filter free beams, recently made available for clinical use, might provide further healthy tissue sparing, particularly in contralateral organs, suggesting their applicability for large and complex targets.

Abstract
PURPOSE To make a patient- and treatment-specific computed tomography (CT) scan and to create a three-dimensional (3D) patient model for superficial hyperthermia treatment planning (SHTP). PATIENTS, MATERIALS, AND METHODS Patients with recurrent breast adenocarcinoma in previously irradiated areas referred for radiotherapy (RT) and hyperthermia (HT) treatment and giving informed consent were included. After insertion of the thermometry catheters in the treatment area, a CT scan in the treatment position was made. RESULTS A total of 26 patients have been, thus far, included in the study. During the study period, five types of adjustments were made to the procedure: (1) marking the RT field with radioopaque markers, (2) making the CT scan after the first HT treatment instead of before, (3) using an air- and foam-filled (dummy) water bolus, (4) a change to radiolucent catheters for which radioopaque markers were needed, and (5) marking the visible/palpable extent of the tumor with radioopaque markers, if necessary. With these adjustments, all necessary information is visible on the CT scan. Each CT slice was automatically segmented into muscle, fat, bone, and air. RT field, catheters, applicators, and tumor lesions, if indicated, were outlined manually using the segmentation program iSeg. Next the model was imported into SEMCAD X, a 3D electromagnetic field simulator. CONCLUSION Using the final procedure to obtain a patient- and treatment-specific CT scan, it is possible to create a 3D model for SHTP.

Abstract
We sought to determine the differences in surgical outcomes associated with adjuvant radiation versus no radiation in patients undergoing concurrent breast oncologic and reconstructive operations. A retrospective review of patients who underwent combined oncologic and plastic surgeries for breast diseases from January 2005 to June 2010 was compared for demographic factors and outcomes by receipt of radiation therapy. During the study period, 175 patients were identified; 25.7 per cent received radiation therapy. Mean patient age was 51 years and median follow-up was 355 days. Overall, 80.2 per cent of patients underwent mastectomy; 19.8 per cent partial mastectomy; 42.1 per cent autologous tissue reconstruction; and 54.8 per cent implant-based reconstruction. There were no significant differences between radiated and nonradiated patients in rates of overall or oncoplastic-specific complications. Lymphedema was the only complication seen more frequently in the radiated arm ( P = 0.03). In our series of carefully selected patients undergoing a variety of reconstructive techniques for repair of partial or total mastectomy defects, radiation was not associated with worse outcomes in patients undergoing immediate breast reconstruction. With careful collaboration among plastic surgeons, breast surgeons, and radiation oncologists, patients requiring breast surgery may safely be considered for reconstruction of partial or total mastectomy defects when adjuvant radiation is required.

Radiotherapy of splenomegaly : a palliative treatment option for a benign phenomenon in malignant diseases. Strahlenther Onkol 2011; 187:221-4. [PMID: 21424304 DOI: 10.1007/s00066-011-2252-4] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2010] [Accepted: 01/24/2011] [Indexed: 10/18/2022]
Abstract
PURPOSE Since the 20(th) century, radiotherapy (RT) has been used for treatment of symptomatic splenomegaly (SM). SM occurs in association with hematologic disorders. The purpose of this analysis was to determine the indication, treatment concepts, and efficiency of RT. MATERIAL AND METHODS Clinical features, treatment concepts, and outcome data during the past 20 years were analyzed. Endpoints were pain relief, symptomatic and hematological response, and treatment-related side effects. RESULTS From 1989-2009, a total of 122 patients received 246 RT courses because of symptomatic SM. Overall 31 patients had chronic myelogenous leukemia (CML), 37 had chronic lymphocytic leukemia (CLL), 23 had osteomyelofibrosis (OMF), 17 had polycythemia vera (PV), 5 had acute myelogenous leukemia, 4 had idiopathic thrombocytopenic purpura (ITP), 3 had non-Hodgkin lymphoma (NHL), and 2 had multiple myeloma (MM). Patients were treated with (60)Co gamma rays or 5-15MV photons. The fraction size ranged from 10-200 cGy and the total dose per treatment course from 30-1600 cGy. Significant pain relief was achieved for 74.8% of the RT courses given for splenic pain. At least 50% regression was attained for 77% of the RT courses given for SM. 36 patients died within 2 months due to the terminal nature of their disease. Of the RT courses applied for cytopenia, 73.6% achieved a significant improvement of hematological parameters and reduction of transfusion need. Notable hematologic toxicities were reported < EORTC/RTOG II°. CONCLUSION The present analysis documents the efficacy of RT. In addition, RT as a palliative treatment option for symptomatic SM should not be forgotten.
