Abstract
BACKGROUND Reduction mammoplasty and mastopexy are potentially complicated by prior breast irradiation as part of breast conserving therapy. Associated tissue changes with therapeutic irradiation have led to surgeons deciding the risks may outweigh potential benefit for those patients. A systematic review of the existing literature was performed to explore surgical outcomes of patients undergoing delayed bilateral reduction mammoplasty or mastopexy following unilateral breast irradiation as part of breast conserving therapy. METHODS Medline, PubMed and EMBASE were searched from 1990 to 2023 according to PRISMA guidelines. Studies were combined by the generic inverse variance method on the natural logarithms of rate ratios (RR) using a random effect model in Review manager 5.4.1. RESULTS Fifteen studies reported outcomes in 188 patients who underwent breast reduction (BR) following unilateral breast conserving surgery and radiotherapy. The median age at BR was 51.5 years (range 39-60), and median time since radiotherapy was 48 months (range 11.7-86). We compared outcomes for irradiated breast (IB) versus non-irradiated breast (NIB). Pooled results showed higher rate of major complications in the IB (RR 2.52, 95%CI 0.96-6.63, p=0.06), but not statistically significant. However, rate of minor complications was significantly higher in the IB (RR 3.97 95%CI 1.86-8.50, p<0.0004). Incidence of fat necrosis as a discrete complication was 2× higher in IB (RR 2.14 95%CI 0.85-5.35, p-value 0.10) compared to the NIB, but not significant. CONCLUSION We found breast reduction to be safe with acceptable risk of major complications. However, the overall complication rate remains higher in IB compared to NIB.

Aesthetic, Quality-of-Life, and Clinical Outcomes after Inferior Pedicle Oncoplastic Reduction Mammoplasty. Aesthetic Plast Surg 2023; 47:905-911. [PMID: 36735002 DOI: 10.1007/s00266-023-03257-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2022] [Accepted: 12/26/2022] [Indexed: 02/04/2023]
Abstract
BACKGROUND Oncoplastic breast surgery is more likely to achieve superior aesthetic outcomes compared to lumpectomy alone. Oncoplastic reduction mammoplasty (ORM) is a volume displacement oncoplastic technique that combines lumpectomy and reduction mammoplasty. Data on aesthetic and quality-of-life (QoL) outcomes after ORM are scarce in the literature. Based on a literature review, this present study reports outcomes on the largest group of ORM patients to date. METHODS A retrospective review was conducted of all patients who underwent ORM between 2011 and 2018 at a tertiary care centre. Patients were excluded if no pedicle information was available or did not undergo post-operative radiotherapy. All patients with available post-operative photographs were aesthetically evaluated by four blinded, independent investigators blinded based on breast symmetry, nipple symmetry, and overall appearance. The BREAST-Q (breast conserving module) was used to assess QoL outcomes. RESULTS Two-hundred-and-sixteen consecutive patients (223 breasts) were included. Macromastia (cup size D or higher) was present in 173 patients (80.1%). Inferior pedicle ORM was utilized in 179 (80.3%) breasts. Eighty-eight patients (40.7%) were aesthetically evaluated, of whom 69 patients (78.4%) had "good", "very good", or "excellent" grades in all aesthetic categories. Seventy-five patients (85.2%) had "good" or better grades in overall appearance. Preoperative ptosis grade, cup size, presence of post-operative complications, and breast specimen weight had no significant correlations with aesthetic grades. Inferior pedicle ORM was associated with a higher "satisfaction with breast" Q-score (p=0.017) compared to other pedicle approaches. CONCLUSION Inferior pedicle ORM achieves objectively excellent aesthetic outcomes and high patient satisfaction with the reconstruction.

Abstract
BACKGROUND Conservative surgery and radiotherapy (CS + RT) have become the standard of care for early-stage breast cancer as an alternative to mastectomy. With the increasing rate of obesity and incidence of macromastia, surgeons increasingly encounter patients with a history of breast radiation desiring breast reduction. However, elective breast surgery after irradiation remains to be controversial due to known adverse effects of radiation, especially on wound healing, and unknown effects of lumpectomy on traditional pedicle choices. Herein, we present our experiences and outcomes of reduction mammaplasties and mastopexies in patients with breast cancer previously treated with CS + RT. METHODS Between 2009 and 2020, 13 patients undergoing reduction mammaplasty or mastopexy, who have previously underwent CS + RT with or without axillary surgery, were included in this study. Surgical techniques and complications, including delayed wound healing, infection, fat necrosis, and nipple-areolar necrosis, were recorded and analyzed based on the irradiated versus nonirradiated sides. RESULTS Of the 13 patients, delayed wound healing occurred in 7% on the irradiated side and 15% on the nonirradiated sides (P > 0.05). No significant correlation was observed between the number of complications and time of elective breast surgery from the last radiation therapy. Complications between irradiated and nonirradiated breasts did not significantly differ in both the reduction mammaplasty and mastopexy groups. CONCLUSIONS Reduction mammaplasty and mastopexy in patients with a history of lumpectomy and breast irradiation can be safely performed and should be considered in those experiencing macromastia or asymmetry post-CS + RT.

Abstract
INTRODUCTION More than 80% of newly diagnosed breast cancers are managed with breast-conserving therapy (BCT). Preservation of cosmetically acceptable breasts is an inherent aim of all breast-conserving efforts-this can, however, be difficult to assess objectively. Compounding this is the difference in perception of breast cosmesis between patients and surgeons. This study compares the concordance of a new subscale-based cosmetic score (TCS) with the patient's perception. METHOD Eastern Health Breast and Cancer Centre conducted this study on patients who had completed their BCT and radiotherapy. Participation was voluntary and involved permitting an assessor (breast surgery fellow or consultant) to grade cosmetic outcomes to generate a Total Cosmesis Score (TCS). The patients blinded to this assessment were then asked to complete the postoperative segment of the BCT module of the Breast-Q questionnaire. TCS from surgeon assessment was compared against patient assessment (questions BQ1i and BQ1k specifically). Cohen's kappa was calculated to define the strength of the inter-rater agreement. RESULTS One hundred twelve patients with a mean age of 59 (range 27-89) participated in the study. TCS was low in 26% and high in 74% of participants. 76% and 69% of participants were satisfied when answering Breast-Q questions 'How your lumpectomy breast looks?' and 'How you look in the mirror unclothed?' respectively (Cohen's k = 0.464, 95% CI 0.337-0.591, p < 0.01). The agreement between the TCS and the patient assessment was poor (Cohen's k = 0.172, 95% CI - 0.020-2.093, p = 0.067). CONCLUSION Cosmetic outcomes scored using TCS by surgeons do not match patient's own assessment of the cosmetic result.

Abstract
Simple Summary To validate the BCCT.core software, the present analysis compares the esthetics assessment by the software in relation to patients’ and physicians’ rating in breast cancer patients after surgery and adjuvant radiotherapy. Agreement rates of the different assessments and their correlation with breast asymmetry indices were evaluated. The assessments of the software and the physicians were significantly correlated with all asymmetry indices, while for patients’ self-assessment, this general correlation was first seen after 2 years. Only a slight agreement between the BCCT.core software and the physicians’ or patients’ assessment was seen, while a moderate and substantial agreement was detected between the physicians’ and the patients’ assessments. The BCCT.core software is a reliable tool to measure asymmetries, but may not sufficiently evaluate the esthetic outcome as perceived by patients. It may be more appropriate for a long-term follow-up, when symmetry seems to increase in importance. Abstract The present analysis compares the esthetics assessment by the BCCT.core software in relation to patients’ and physicians’ ratings, based on the IMRT-MC2 trial. Within this trial, breast cancer patients received breast-conserving surgery (BCS) and adjuvant radiotherapy. At the baseline, 6 weeks, and 2 years after radiotherapy, photos of the breasts were assessed by the software and patients’ and physicians’ assessments were performed. Agreement rates of the assessments and their correlation with breast asymmetry indices were evaluated. The assessments of the software and the physicians were significantly correlated with asymmetry indices. Before and 6 weeks after radiotherapy, the patients’ self-assessment was only correlated with the lower breast contour (LBC) and upward nipple retraction (UNR), while after 2 years, there was also a correlation with other indices. Only a slight agreement between the BCCT.core software and the physicians’ or patients’ assessment was seen, while a moderate and substantial agreement was detected between the physicians’ and the patients’ assessment after 6 weeks and 2 years, respectively. The BCCT.core software is a reliable tool to measure asymmetries, but may not sufficiently evaluate the esthetic outcome as perceived by patients. It may be more appropriate for a long-term follow-up, when symmetry appears to increase in importance.

Abstract
Introduction
This article is an attempt to formulate certain guidelines for planning of zone-wise reconstruction after breast conservation surgery. The planning involves applying reduction mammoplasty principles with certain modifications to address the defect.
Patients and Methods
This is a retrospective study of 61 patients with breast cancer who underwent breast conservation surgery and reconstruction of partial breast defects with oncoplastic techniques between January 2014 to March 2019. Patients having low tumor to breast ratio and thus good candidates for volume displacement techniques were included in the study.
Results
A total of 61 breast cancer cases were included; 22 cases were located in zone 1, nine in zone 2, seven in zone 3, three in zone 4, four in zone 5, one in zone 6, 12 in zone 7, two in zone 8, and three in zone 9. The most common pedicle design used was superomedial in 38 cases, followed by inferior in 19 and medial in 6 cases. Vertical short scar technique was used in 33 cases and Wise pattern skin incision in 30 cases. Follow-up period ranged from 4 months to 65 months, with a mean of 31 months. Four patients had partial skin necrosis, three had suture line dehiscence, two had wound infection, one had seroma, and eight patients had fat necrosis. All patients were satisfied with the cosmetic outcome.
Conclusion
Breast oncoplastic techniques are effective, reliable, oncologically safe, and conducted with minimal complications in patients with moderately large ptotic breasts, thereby making planning easier and more reproducible by following the reconstruction procedures described in the article. We believe that these techniques should be incorporated in the armamentarium of every plastic surgeon to manage the defects created after breast conservation surgery, in order to achieve the best cosmetic outcomes.

Abstract
The purpose of this study was to evaluate the impact of breast size on acute and late side effects in breast cancer (BC) patients treated with hypofractionated radiotherapy (Hypo-RT). In this study we analyzed patients over 50 years with a diagnosis of early BC, candidate for Hypo-RT after conservative surgery. Acute and late skin toxicities were evaluated in accordance with the RTOG scale. Multivariable logistic analysis was performed using dosimetric/anatomical factors resulted associated with toxicity outcome in univariable analysis. Among patients treated between 2009 and 2015, 425 had at least 5 years of follow-up. At RT end, acute skin toxicity ≥ G2 and edema ≥ G2 occurred in 88 (20.7%) and 4 (0.9%) patients, respectively. The multivariable analysis showed association of skin toxicity with boost administration (p < 0.01), treated skin area (TSA) receiving more than 20 Gy (p = 0.027) and breast volume receiving 105% of the prescription dose (V105%) (p = 0.016), but not breast size. At 5 years after RT, fibrosis ≥ G1 occurred in 89 (20.9%) patients and edema ≥ G1 in 36 (8.5%) patients. Fibrosis resulted associated with breast volume ≥ 1000 cm3 (p = 0.04) and hypertension (p = 0.04). As for edema, multivariable logistic analysis showed a correlation with hypertension and logarithm of age, but not with boost administration. Breast volume had an unclear impact (p = 0.055). A recurrent association was found between acute and late toxicities and breast V105%, which is correlated with breast size. This may suggest that a more homogenous RT technique may be preferred for patients with larger breast size.

[PMID: 34082363 DOI: 10.1016/j.ctarc.2021.100403] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2021] [Revised: 04/27/2021] [Accepted: 05/10/2021] [Indexed: 12/13/2022]
Abstract
PURPOSE Radiation dermatitis (RD) is a side effect that frequently arises during radiotherapy (RT) in breast cancer patients. The present study investigates possible predictive factors of RD, as well as the use of skin treatments to manage symptoms. METHODS Demographic and treatment characteristics were collected retrospectively, while skin symptoms and treatments were collected prospectively for patients who received adjuvant RT between December 2013 and November 2015. Patients were seen weekly by clinicians throughout treatment, during which a clinician-reported survey was completed on RD symptoms and skin treatments. Possible predictive factors were correlated with skin outcomes through a univariate ordinal logistic regression analysis. RESULTS A total of 1093 patients were included in this analysis. Predictive factors for erythema included dose fractionation (p<0.0001), tissue volume irradiated by tangential fields (p = 0.01), and administration of a boost (p = 0.005). High BMI (≥30 kg/m2) (p = 0.0004) and boost (p = 0.02) were predictive of edema. A dose of 50 Gy/25 (p<0.0001) and a high irradiated tissue volume (p = 0.0001) were predictive of desquamation. A dose of 50 Gy/25 (p = 0.0005) and high BMI (p = 0.02) were predictors of pain. Bolus use was the only factor associated with bleeding (p = 0.02). Patients who developed desquamation were likely to receive corticosteroids/antihistamines (p<0.0001), topical antibiotics/antifungals (p<0.001), and dressings (p<0.0001). CONCLUSION The findings of this study provide evidence of potential predictors of RD and methods of symptom management based on symptom severity. Prevention of RD is needed among high-risk groups, such as patients with a high BMI or receiving a standard fractionation, boost, or bolus.

Abstract
Breast cancer is the most common cancer diagnosed in women, and early stages are treated with lumpectomy and irradiation. Irradiation, however, leads to reduced vascularization and fibrosis, which may influence the cosmetic outcome unfavourably and increase complications after subsequent surgery on irradiated breasts. Patients with significant asymmetry after treatment may desire corrective reduction mammoplasty or mastopexy, but this may be associated with increased complication rates. This systematic review and meta-analysis aimed to investigate postoperative complication rates after bilateral reduction mammoplasty or mastopexy in women who had undergone unilateral lumpectomy and irradiation. PubMed, Medline, EMBASE and Cochrane databases were searched for eligible studies. After screening titles and abstracts, 14 full text studies were reviewed, and 7 of these were included in the analysis. The meta-analysis showed a significantly higher complication rate in the irradiated breast compared to the non-irradiated breast, rate ratio 4.82 (95% CI: 1.58, 14.70), p = 0.006. The complication rate was 54% in the irradiated breast (58/107) compared to 8% (9/107) in the non-irradiated breast (p = 0.034). This study suggests that reduction mammoplasty or mastopexy in the previously irradiated breast is associated with a significantly increased risk of complications. Careful patient selection and information are paramount in the treatment of this patient group.

A study of the dosimetric impact of daily setup variations measured with cone-beam CT on three-dimensional conformal radiotherapy for early-stage breast cancer delivered in the prone position. J Appl Clin Med Phys 2020; 21:146-154. [PMID: 33124774 PMCID: PMC7769386 DOI: 10.1002/acm2.13080] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2019] [Revised: 08/04/2020] [Accepted: 10/05/2020] [Indexed: 11/11/2022] Open
Abstract
PURPOSE To evaluate the dosimetric impact of daily positioning variations measured with cone-beam computed tomography (CBCT) on whole-breast radiotherapy patients treated in the prone position. METHODS Daily CBCT was prospectively acquired for 30 consecutive patients positioned prone. Treatment for early-stage (≤II) breast cancer was prescribed with standard dose (50 Gy/25 fractions) or hypofractionation (42.56 Gy/16 fractions) for 13 and 17 patients, respectively. Systematic and random errors were calculated from the translational CBCT shifts and used to determine population-based setup margins. Mean translations (±one standard deviation) for each patient were used to simulate the dosimetric impact on targets (PTV_eval and lumpectomy cavity), heart, and lung. Paired Student's t tests at α = 0.01 were used to compare dose metrics after correction for multiple testing (P < 0.002). Significant correlation coefficients were used to identify associations (P < 0.01). RESULTS Of 597 total fractions, 20 ± 13% required patient rotation. Mean translations were 0.29 ± 0.27 cm, 0.41 ± 0.34 cm, and 0.48 ± 0.33 cm in the anterior-posterior, superior-inferior, and lateral directions leading to calculated setup margins of 0.63, 0.88, and 1.10 cm, respectively. Average three-dimensional (3D) shifts correlated with the maximum distance of breast tissue from the sternum (r = 0.62) but not with body-mass index. Simulated shifts showed significant, but minor, changes in dose metrics for PTV_eval, lung, and heart. For left-sided treatments (n = 18), mean heart dose increased from 109 ± 75 cGy to 148 ± 115 cGy. Shifts from the original plan caused PTV_eval hotspots (V105%) to increase by 5.2% ± 3.8%, which correlated with the total MU of wedged fields (r = 0.59). No significant change in V95% to the cavity was found. CONCLUSIONS Large translational variations that occur when positioning prone breast patients had small but significant dosimetric effects on 3DCRT plans. Daily CBCT may still be necessary to correct for rotational variations that occur in 20% of treatments. To maintain planned dose metrics, unintended beam shifts toward the heart and the contribution of wedged fields should be minimized.

Hypofractionated Whole Breast Irradiation and Simultaneous Integrated Boost in Large-breasted Patients: Long-term Toxicity and Cosmesis. Clin Breast Cancer 2020; 20:527-533. [PMID: 32665192 DOI: 10.1016/j.clbc.2020.06.005] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2020] [Revised: 06/03/2020] [Accepted: 06/12/2020] [Indexed: 12/18/2022]
Abstract
INTRODUCTION The purpose of this study was to evaluate the impact of breast size on long-term toxicity and cosmesis in patients with breast cancer treated with hypofractionated simultaneous integrated boost (SIB) using volumetric modulated arc therapy (VMAT). PATIENTS AND METHODS Patients with early stage breast cancer were treated with 3-week hypofractionated SIB-VMAT to the whole breast (40.5 Gy) and tumor bed (48 Gy). Two cohorts were identified: small/medium- (< 1000 cm3) and large- (> 1000 cm3) breasted patients. Acute and late (at 2 and 5 years) skin toxicity and cosmetic data were analyzed. Univariate and multivariate analysis evaluated associations between toxicity and dosimetric/anatomical variables. RESULTS From August 2010 to March 2017, a total of 1160 patients were treated; 831 had at least 2 years of follow-up and were analyzed. Treated skin area (TSA) receiving at least 20 Gy > 400 cm2 and V105% of Boost > 5 cm3 were significant predictors for acute skin toxicity. Multivariate analysis at 2 years was significant for boost volume > 70 cm3, TSA > 400 cm2, and breast size > 1500 cm3. At 5 year analysis (352 patients), none of the analyzed variables was significant. For cosmetic outcome, only the breast size (> 1000 cm3) and the boost size > 70 cm3 at 2 and 5 years, respectively, confirmed significance. CONCLUSIONS The TSA > 400 cm2 resulted as a significant predictor of both acute and late skin toxicity at 2 years; however, at 5 years, no breast size or dosimetric parameter suggested indications for increased toxicity. A worse cosmetic outcome was recorded at the 2-year follow up for large breasts, but was not confirmed at the 5-year follow-up. These long-term data suggest that hypofractionated SIB-VMAT is a viable modality also in large-breasted patients.

Abstract
PURPOSE This review was to focus on breast brachytherapy cosmetic assessment methods state of the art and to define the advantages and disadvantages related to. METHODS AND MATERIALS We conducted a literature review of the major experience on breast brachytherapy cosmetic assessment methods in several databases (PubMed, Scopus, and Google Scholar databases). To identify the relevant works, a task force screened citations at title and abstract level to identify potentially relevant paper. An expert board reviewed and approved the text. The assessment systems were classified into three main groups: (1) the Oncological Toxicity Scales, (2) the Independent Patients Perspective Measures, (3) the Patient-Related Outcome Measures. Each cosmetic assessment method was evaluated following six parameters: (1) anatomical site, (2) advantages, (3) disadvantages, (4) subjective/objective, (5) quantitative/qualitative, (6) computers or pictures needs. RESULTS Eleven assessment methods were selected. Three methods were classified as Oncological Toxicity Scale, six in the Independent Patients Perspective Measures classification, and two as Patient-Related Outcome Measures. Six methods are subjective, while eight are objective. Four systems are classified as quantitative, four as qualitative while three both. Five systems need informatics support. Moreover, each method was discussed individually reporting the main characteristics and peculiarities. CONCLUSIONS Cosmesis is one major end point for the patient who has a malignancy of low lethal potential. In modern personalized medicine, there is a need for standardized cosmetic outcome assessments to analyze and compare the results of treatments. No gold standard methods currently exist. The result of this review is to summarize the various cosmesis methods, defining the strengths and weaknesses of each one and giving a line in research and clinical practice.

Dosimetric effects of the kV based image-guided radiation therapy of prone breast external beam radiation: Towards the optimized imaging frequency. J Appl Clin Med Phys 2018; 20:212-219.

Abstract
PURPOSE For prone breast treatment, daily image-guided radiation therapy (IGRT) allows couch shifting to correct breast position relative to the treatment field. This work investigates the dosimetric effect of reducing kV imaging frequencies and the feasibility of optimizing the frequency using patient anatomy or their first 3-day shifts. METHOD Thirty-seven prone breast patients who had been treated with skin marker alignment followed by daily kV were retrospectively analyzed. Three IGRT schemes (daily-kV, weekly-kV, no-kV) were simulated, assuming that fractions with kV imaging deliver a dose distribution equivalent to that in computed tomography (CT) planning, whereas other fractions yield a dose distribution as recreated by shifting the CT plan isocenter back to its position before the couch shift was applied. Treatment dose to targets (breast and lumpectomy cavity [LPC]) and organs at risks (OAR)s (heart, ipsilateral lung) in different schemes were calculated. Patient anatomy information on CT plans and first 3-day couch shift data were analyzed to investigate whether these factors could guide imaging scheme optimization. RESULTS When kV imaging frequency was reduced, the percentage dose changes (δD) for breast and LPC objectives (average <1%) were smaller than those for heart and lung (average 28%-31% for Dmean ). In general, the δD of no-kV imaging was approximately that of weekly kV imaging × a factor of 1.2-1.4. Although most dose objectives were not affected, the potential higher heart dose may be of concern. No strong correlation was found between δD for different kV frequencies and patient anatomy size/distance or the first 3-day couch shift data. CONCLUSIONS Despite resulting in lower imaging dose, time, cost, and similar target coverage, a reduction in kV imaging frequency may introduce higher heart complication risk. Daily kVs are needed more in left-sided breast patients. A less frequent imaging schedule, if considered, cannot be individually optimized using CT anatomic features or early shift data.

Abstract
INTRODUCTION Evaluation of patient characteristics inducing toxicity in breast radiotherapy, using simultaneous modeling of multiple endpoints. METHODS AND MATERIALS In 269 early-stage breast cancer patients treated with whole-breast irradiation (WBI) after breast-conserving surgery, toxicity was scored, based on five dichotomized endpoints. Five logistic regression models were fitted, one for each endpoint and the effect sizes of all variables were estimated using maximum likelihood (MLE). The MLEs are improved with James-Stein estimates (JSEs). The method combines all the MLEs, obtained for the same variable but from different endpoints. Misclassification errors were computed using MLE- and JSE-based prediction models. For associations, p-values from the sum of squares of MLEs were compared with p-values from the Standardized Total Average Toxicity (STAT) Score. RESULTS With JSEs, 19 highest ranked variables were predictive of the five different endpoints. Important variables increasing radiation-induced toxicity were chemotherapy, age, SATB2 rs2881208 SNP and nodal irradiation. Treatment position (prone position) was most protective and ranked eighth. Overall, the misclassification errors were 45% and 34% for the MLE- and JSE-based models, respectively. p-Values from the sum of squares of MLEs and p-values from STAT score led to very similar conclusions, except for the variables nodal irradiation and treatment position, for which STAT p-values suggested an association with radiosensitivity, whereas p-values from the sum of squares indicated no association. Breast volume was ranked as the most significant variable in both strategies. DISCUSSION The James-Stein estimator was used for selecting variables that are predictive for multiple toxicity endpoints. With this estimator, 19 variables were predictive for all toxicities of which four were significantly associated with overall radiosensitivity. JSEs led to almost 25% reduction in the misclassification error rate compared to conventional MLEs. Finally, patient characteristics that are associated with radiosensitivity were identified without explicitly quantifying radiosensitivity.

Abstract
In women with large and pendulous breasts postoperative radiotherapy in the supine position could represent a technical challenge because of the resulting dose inhomogeneity and the large amount of lung and heart receiving a high percentage of the prescribed dose. Breast-conserving surgery is therefore relatively contraindicated in these patients. Alternative positions for radiation therapy treatment have been proposed, and prone breast irradiation in particular has been recognized as a useful alternative to conventional treatment in the supine position. We report the case of a large-breasted patient treated in prone position in our radiation therapy division.

Abstract
Oncoplastic breast conservation surgery (OBCS) is increasingly becoming part of routine breast cancer surgical management. OBCS may be viewed as an extension of standard breast conservation surgery for resecting tumors of larger sizes without compromising on cosmetic outcome, or as an alternative to mastectomy. High quality evidence to support the oncological safety and benefits of OBCS is lacking. This review will focus on the best available level of evidence and address key issues regarding oncological safety in OBCS, such as tumor resection margins and re-excision rates, local recurrence and patient outcome, postoperative complications and adjuvant therapy delivery, and briefly discuss cosmetic outcome in OBCS. Comparative observational studies and systematic review report no poorer outcomes compared with standard breast conservation surgery. More evidence needs to be generated to support the oncological safety and improved aesthetic outcome. Prospective data collection will significantly contribute to the generation of stronger evidence.

Prospective study of postoperative whole breast radiotherapy for Japanese large-breasted women: a clinical and dosimetric comparisons between supine and prone positions and a dose measurement using a breast phantom. BMC Cancer 2016; 16:757. [PMID: 27681376 PMCID: PMC5041564 DOI: 10.1186/s12885-016-2794-z] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2016] [Accepted: 09/19/2016] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND This prospective study aimed to compare dose volume histograms (DVH) of the breasts and organs at risk (OARs) of whole breast radiotherapy in the supine and prone positions, and frequency and severity of acute and late toxicities were analyzed. METHODS Early-stage breast cancer patients with large breasts (Japanese bra size C or larger, or the widest measurements of the bust ≥ 95 cm) undergoing partial mastectomy participated in this study. CT-based treatment plans were made in each position, and various dosimetric parameters for the breast and OARs were calculated to compare the supine and prone radiotherapy plans. The actual treatment was delivered in the position regarded as better. RESULTS From 2009 to 2010, 22 patients were prospectively accrued. Median follow-up period was 58 months. The homogeneity index and lung doses were significantly lower in the prone position (P = 0.008, P < 0.0001 and P < 0.0001, respectively). Cardiac dose showed no significant differences between two positions. By comparing two plans, the prone position was chosen in 77 % of the patients. In the prone position, ≥ grade 2 acute dermatitis were seen in 47 % of patients treated, whereas 20 % of the patients treated in the supine position had grade 2 and no cases of grade 3, although without a statistical significance of the rates of ≥ grade 2 acute dermatitis between the two positions (P = 0.28). The actual dose measurement using a breast phantom revealed significantly higher surface dose of the breast treated in the prone position than that in the supine position. CONCLUSIONS Breast irradiation in the prone position improves PTV homogeneity and lowers doses to the OARs in the Japanese large-breast patients. However meticulous positioning of the breast in the prone board avoiding the bolus effect is necessary to prevent acute dermatitis.

Abstract
AIM To quantify and compare setup errors between small and large breast patients undergoing intact breast radiotherapy. METHODS 20 patients were inducted. 10 small/moderate size breast in arm I and 10 large breast in arm II. Two orthogonal and one lateral tangent portal images (PIs) were obtained and analyzed for systematic (Σ) and random (σ) errors. Effect of no action level (NAL) was also evaluated retrospectively. RESULTS 142 PIs were analyzed. Σ(mm) was 3.2 versus 6.7 (p = 0.41) in the mediolateral (ML) direction, 2.1 versus 2.9 (p = 0.06) in the craniocaudal (CC) and 2.2 versus 3.6 (p = 0.08) in the anteroposterior (AP) direction in small and large breast, respectively. σ(mm) was 3.0, 3.3 and 3.3 for small breast and 4.1, 3.7 and 3.2 for large breast in the ML, CC and AP direction (p = 0.07, 0.86, 0.37), respectively. 3 D Σ(mm) was 2.7 versus 4.2 (p = 0.01) and σ(mm) was 2.5 versus 3.2 (p = 0.14) in arm I and II, respectively. The standard deviation (SD) of variations (mm) in breast contour depicted by central lung distance (CLD) was 5.9 versus 7.4 (p < 0.001), central flash distance (CFD) 6.6 versus 10.5 (p = 0.002), inferior central margin (ICM) 4 versus 4.9 (p < 0.001) in arm I and II, respectively. NAL showed a significant reduction of systematic error in large breast in the mediolateral direction only. CONCLUSION Wing board can be used in a busy radiotherapy department for setting up breast patients with a margin of 1.1 cm, 0.76 cm and 0.71 cm for small breasts and 1.96 cm, 1.12 cm and 0.98 cm for large breast in the ML, AP and CC directions, respectively. The large PTV margin in the mediolateral direction in large breast can be reduced using NAL. Further research is needed to optimize positioning of large breasted women.

Comparison of plan optimization for single and dual volumetric-modulated arc therapy versus intensity-modulated radiation therapy during post-mastectomy regional irradiation. Oncol Lett 2016; 11:3389-3394. [PMID: 27123122 DOI: 10.3892/ol.2016.4376] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2014] [Accepted: 07/28/2015] [Indexed: 11/06/2022] Open
Abstract
The aim of the present study was to investigate volumetric-modulated arc therapy (VMAT) with single arc (1ARC) and dual arc (2ARC), and intensity-modulated radiation therapy (IMRT), and to evaluate the quality and delivery efficiency of post-mastectomy regional irradiation. A total of 24 female patients who required post-mastectomy regional irradiation were enrolled into the current study, and 1ARC, 2ARC and IMRT plans were designed for each individual patient. The quality of these plans was evaluated by calculating the homogeneity index (HI), conformity index (CI) and specific volume dose to the ipsilateral lung, double lungs, contralateral breast, heart and spinal cord. For the delivery efficiency of these plans, the total treatment time (TTT) and the number of monitor units (MUs) were evaluated. The 1ARC and 2ARC VMAT plans exhibited significantly better HIs and CIs than IMRT. For dose-volume histogram analysis, 1ARC and 2ARC VMAT spared a more specific volume dose to the ipsilateral lung, double lungs, contralateral breast, heart and spinal cord than IMRT (P<0.05). A lower MU per 2.0-Gy fraction was required for 1ARC (539 MU) and 2ARC (608 MU) than for IMRT (1,051 MU). Thus, TTT was correspondingly reduced in 1ARC and 2ARC compared to IMRT (P<0.05). There was no significant dose-volume difference in all the organs at risk (OARs) between the 1ARC and 2ARC plans (P>0.05), and 2ARC VMAT displayed a better HI and CI than 1ARC VMAT (P<0.05). By contrast, 1ARC VMAT was superior to 2ARC VAMT with regard to MU and TTT (P<0.05). The 1ARC and 2ARC VMAT plans demonstrated significantly better dose distribution in a shorter treatment time than IMRT for post-mastectomy regional irradiation, and spared the majority of OARs without compromising target coverage. The results of the present study suggest that 2ARC VMAT may be an alternative to 1ARC in order to obtain a more optimal HI and CI.

Oncoplastic reduction mammoplasty for breast cancer in women with macromastia: long term aesthetic, functional and satisfaction outcomes. Contemp Oncol (Pozn) 2016; 20:256-60. [PMID: 27647991 PMCID: PMC5013678 DOI: 10.5114/wo.2015.55272] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2014] [Accepted: 07/13/2015] [Indexed: 11/17/2022] Open
Abstract
AIM OF THE STUDY Despite the increase in studies concerning oncoplastic reduction mammoplasty (ORM), data showing long-term aesthetic and patient satisfaction for ORM in patients with macromastia remain limited. Therefore, this study evaluated the long-term results of tumorectomy and concomitant bilateral ORM for early-stage breast cancer patients with macromastia in terms of cosmesis, patient satisfaction, and functional outcomes. MATERIAL AND METHODS Retrospective data of patients with macromastia undergoing ORM for breast cancer between 1996 and 2011 were examined and evaluated regarding the aesthetic results, patient satisfaction, and functional outcomes. RESULTS The median age of the 82 patients was 50 years. The median follow-up was 120 months (range: 28-212 months). The median breast volume was 1402 cm(3), and the median weight of the excised breast material was 679 g. A good or excellent evaluation of the cosmetic outcome was as follows: self-evaluation: 84.1% at the early-stage, 80.3% at the later stage; panel evaluation: 75.4% at the late-stage. Median patient satisfaction rates were 9.1% for early-stage disease and 8.8% for late-stage disease. Reduced mobility and intertrigo improved by three-fold during the post-operative period. CONCLUSIONS ORM for early-stage breast cancer in women with macromastia results in good cosmesis in both the early-stage and long-term, and is quite acceptable for use in patients. Patients reacted favorably to the prospect of having their breast cancer and macromastia treated in a single session, and positive results continued over the long-term.

Abstract
OBJECTIVE The objective of the present study was to identify acute skin toxicity risk factors linked to the anthropometric characteristics of patients with breast cancer treated with radiation therapy. METHODS Consecutive patients with breast cancer were enrolled after breast-conserving surgery and before radiotherapy course. Acute skin toxicity was assessed weekly during the 7 weeks of radiotherapy with the International Classification from National Cancer Institute. Grade 2 defined acute skin toxicity. Patient characteristics and anthropometric measurements were collected. RESULTS 54 patients were enrolled in 2013. Eight patients (14.8%) had grade ≥2 toxicity. The average weight and chest size were 65.5 kg and 93.6 cm, respectively. Bra cup size is significantly associated with a risk of grade 2 dermatitis [odds ratio (OR) 3.46, 95% confidence interval (CI) (1.29-11.92), p = 0.02]. Anthropometric breast fat mass measurements, such as thickness of left [OR 2.72, 95% CI (1.08-8.26), p = 0.04] and right [OR 2.45, 95% CI (0.99-7.27), p = 0.05] axillary fat, are correlated with an increased risk. Distance between the pectoral muscle and nipple is a reproducible measurement of breast size and is associated with acute skin toxicity with significant tendency (OR = 2.21, 95% CI (0.97-5.98), p = 0.07). CONCLUSION Breast size and its different anthropometric measurements (thickness of left and right axillary fat, nipple-to-pectoral muscle distance) are correlated with the risk of skin toxicity. ADVANCES IN KNOWLEDGE The present article analyses several characteristics and anthropomorphic measurements of breast in order to assess breast size. A standardized and reproducible protocol to measure breast volume is described.

Abstract
The aim of this study is to discuss indications, advantages, disadvantages, oncologic and aesthetic results of Oncoplastic Surgery (OBS). Pubmed and Medline database were searched for articles published between 1998 and 2014 for keywords: oncoplastic breast surgery, therapeutic mammoplasty, oncoplastic breast reduction, synchrenous reconstructions. Role of OBS in breast cancer surgery, its aspects to be considered, its value and results have been interpreted. This technique has advantages by providing more extensive tumourectomy, yielding better aesthetic results compared with breast conserving surgery, allowing oncoplastic reduction in breast cancer patients with macromastia, with higher patient satisfaction and quality of life and by being inexpensive due to single session practice. As for its disadvantages are: re-excision is more difficult, risk for mastectomy is higher, it is depent on the Surgeron's experience, it has a risk for delay in adjuvant therapies and its requirement for additional imaging studies during management. Main indications are patients with small tumour/breast volume, macromastia, multifocality, procedures which can disrupt breast cosmesis such as surgeries for upper inner breas tquadrient tumours. Contraindications are positive margin problems after wide excision, diffuse malign microcalsifications, inflammatory breast cancer, history of radiotherapy and patients' preferences. Despite low evidence level, Oncoplastic Breast Surgery seems to be both reliable and acceptable in terms of oncologic and aesthetic aspects. Oncoplastic Breast Surgery increase the application rate of breast conserving surgery by obviating practical limitations and improve the results of breast conserving surgery. Correct patient and technique choice in OBS is vital for optimization of post surgical.

Abstract
Breast-conservation surgery (BCS) is established as a safe option for most women with early breast cancer. Recently, advances in oncoplastic techniques have reduced surgical trauma and thus are capable of preserving the breast form and quality of life. In spite of the most BCS defects can be managed with primary closure, the aesthetic outcome may be unpredictable. Oncoplastic reconstruction may begin at the time of BCS (immediate), weeks (delayed-immediate) or months to years afterwards (delayed). With immediate reconstruction, the surgical process is smooth, since both procedures can be associated in one operative setting. Additionally, it permits wider excision of the tumor, with a superior mean volume of the specimen and potentially reducing the incidence of margin involvement. The oncoplastic techniques are related to volume displacement or replacement procedures including local flaps, latissimus dorsi myocutaneous flap and reduction mammaplasty/masthopexy. Regardless of the fact that there is no consensus concerning the best approach, the criteria are determined by the surgeon's experience and the size of the defect in relation to the size of the remaining breast. On the basis of our 15-year experience, it is possible to identify trends in types of breast defects and to develop an algorithm for immediate BCS reconstruction on the basis of the initial breast volume, the extent/location of glandular tissue ressection and the remaining available breast tissue. The main advantages of the technique utilized should include reproducibility, low interference with the oncologic treatment and long-term results. Surgical planning should include the patients's preferences, and chiefly addressing individual reconstructive requirements, enabling each patient to receive an individual "custom-made" reconstruction.

Abstract
PURPOSE Treating patients with large or pendulous breasts is challenging. Although brassiere cups are currently in use, no study has yet been carried out to assess their dosimetric impact. The aim of the present study was to evaluate the possible dosimetric advantages of the use of breast cups on patients with large or pendulous breasts. MATERIALS AND METHODS Two CT studies were carried out on 12 breast cancer patients with large or pendulous breasts, with one study involving the use of breast cups. Radiation plans were developed in accordance with each of the CT studies. The following were compared: planning target volume (PTV), volume irradiated by the 95% isodose, conformity index, homogeneity index, mean lung dose, and mean heart dose was also compared for left breast treatment. The plan involving the use of cups was found to be the best option, leading to all patients being treated with cups. The resulting acute toxicity and cosmesis were also recorded. Both scenarios involved the use of film dosimetry to evaluate the skin doses. RESULTS The use of breast cups resulted in a significant reduction of the PTV volume (from 1640 cm3 to 1283 cm3), of the irradiated volume (from 2154 cm3 to 1477 cm3) and of the conformity index (from 1383 to 1213). Despite slight improvements in the homogeneity index (from 0.12 to 0.10), statistical significance was not attained. The use of breast cups also led to significant dose reductions in V20 for lung (from 13.7% to 1.7%) and V5 for heart (from 9.8% to 2.7%). No differences in acute toxicity or cosmesis were observed compared to patients treated without cups. CONCLUSIONS Our results show that the use of brassiere cups during breast radiation therapy leads to improvements in the main dosimetric factors analyzed. Furthermore, modifications to standard irradiation protocols are not required. In summary, we consider the technique of using breast cups with radiation therapy highly appropriate when treating breast cancer patients with large or pendulous breasts.

Abstract
Background The latissimus dorsi myocutaneous flap (LDMCF) is frequently applied to breast cancer patients for breast reconstruction. However, the LDMCF is considered inappropriate for patients with ptotic breast. The authors investigated combining LDMCF and two local flaps for large defects of the breast after partial mastectomy in patients with ptosis. Methods Nineteen patients with breast cancer underwent a partial mastectomy with immediate reconstruction. Reconstruction methods consisted of LDMCF, thoraco-epigastric flap, and inferior pedicled rotational local flap, referred to as a combined pedicle flap. The cosmetic results were self-assessed after chemotherapy and radiotherapy by a four-point scoring system. Results Ptosis was graded as follows: two patients with grade 1, 10 patients with grade 2, and seven patients with grade 3. The mean tumor size was 2.7 cm and multifocality was identified in 11 patients (57.9%). The mean excised volume was 468.5 cm3 and the percentage of excised volume was 46.2%. The cosmetic results were excellent in five patients, good in seven patients, fair in six patients, and poor in one patient. Conclusion The combined pedicle flap, consisting of LDMCF, thoraco-epigastric flap, and inferior pedicled rotational local flap, allows good cosmesis in breast cancer patients with large breasts or ptosis despite a wide excision.

Abstract
Breast-conservation surgery (BCS) is established as a safe surgical treatment for most patients with early breast cancer. Recently, advances in oncoplastic techniques are capable of preserving the breast form and quality of life. Although most BCS defects can be managed with primary closure, the aesthetic outcome may be unpredictable. Among technical options, therapeutic reduction mammaplasty (TRM) remains a useful procedure since the BCS defect can be repaired and the preoperative appearance can be improved, resulting in more proportional breasts. As a consequence of rich breast tissue vascularization, the greater part of reduction techniques have based their planning on preserving the pedicle of the nipple-areola complex after tumor removal. Reliable circulation and improvement of a conical shape to the breast are commonly described in TRM reconstructions. With an immediate approach, the surgical process is smooth since both procedures can be carried out in one operative setting. Additionally, it permits wider excision of the tumor, with a superior mean volume of the specimen and potentially reduces the incidence of margin involvement. Regardless of the fact that there is no consensus concerning the best TRM technique, the criteria is determined by the surgeon’s experience, the extent/location of glandular tissue resection and the size of the defect in relation to the size of the remaining breast. The main advantages of the technique utilized should include reproducibility, low interference with the oncological treatment and long-term results. The success of the procedure depends on patient selection, coordinated planning and careful intra-operative management.

Abstract
PURPOSE This paper introduces a new external beam radiotherapy device named GammaPod that is dedicated for stereotactic radiotherapy of breast cancer. METHODS The design goal of the GammaPod as a dedicated system for treating breast cancer is the ability to deliver ablative doses with sharp gradients under stereotactic image guidance. Stereotactic localization of the breast is achieved by a vacuum-assisted breast immobilization cup with built-in stereotactic frame. Highly focused radiation is achieved at the isocenter due to the cross-firing from 36 radiation arcs generated by rotating 36 individual Cobalt-60 beams. The dedicated treatment planning system optimizes an optimal path of the focal spot using an optimization algorithm borrowed from computational geometry such that the target can be covered by 90%-95% of the prescription dose and the doses to surrounding tissues are minimized. The treatment plan is intended to be delivered with continuous motion of the treatment couch. In this paper the authors described in detail the gamma radiation unit, stereotactic localization of the breast, and the treatment planning system of the GammaPod system. RESULTS A prototype GammaPod system was installed at University of Maryland Medical Center and has gone through a thorough functional, geometric, and dosimetric testing. The mechanical and functional performances of the system all meet the functional specifications. CONCLUSIONS An image-guided breast stereotactic radiotherapy device, named GammaPod, has been developed to deliver highly focused and localized doses to a target in the breast under stereotactic image guidance. It is envisioned that the GammaPod technology has the potential to significantly shorten radiation treatments and even eliminate surgery by ablating the tumor and sterilizing the tumor bed simultaneously.

Abstract
Background Early stage breast cancer patients are long-term survivors and finding techniques that may lower acute and late radiotherapy-induced toxicity is crucial. We compared dosimetry of wedged tangential fields (W-TF), tangential field intensity-modulated radiotherapy (TF-IMRT) and multi-beam IMRT (MB-IMRT) in prone and supine positions for whole-breast irradiation (WBI). Methods MB-IMRT, TF-IMRT and W-TF treatment plans in prone and supine positions were generated for 18 unselected breast cancer patients. The median prescription dose to the optimized planning target volume (PTVoptim) was 50 Gy in 25 fractions. Dose-volume parameters and indices of conformity were calculated for the PTVoptim and organs-at-risk. Results Prone MB-IMRT achieved (p<0.01) the best dose homogeneity compared to WTF in the prone position and WTF and MB-IMRT in the supine position. Prone IMRT scored better for all dose indices. MB-IMRT lowered lung and heart dose (p<0.05) in supine position, however the lowest ipsilateral lung doses (p<0.001) were in prone position. In left-sided breast cancer patients population averages for heart sparing by radiation dose was better in prone position; though non-significant. For patients with a PTVoptim volume ≥600 cc heart dose was consistently lower in prone position; while for patients with smaller breasts heart dose metrics were comparable or worse compared to supine MB-IMRT. Doses to the contralateral breast were similar regardless of position or technique. Dosimetry of prone MB-IMRT and prone TF-IMRT differed slightly. Conclusions MB-IMRT is the treatment of choice in supine position. Prone IMRT is superior to any supine treatment for right-sided breast cancer patients and left-sided breast cancer patients with larger breasts by obtaining better conformity indices, target dose distribution and sparing of the organs-at-risk. The influence of treatment techniques in prone position is less pronounced; moreover dosimetric differences between TF-IMRT and MB-IMRT are rather small.

Abstract
OBJECTIVE The primary objectives of this systematic review on oncoplastic breast surgery (OPBS) were to evaluate the oncological and cosmetic outcomes of OPBS. The secondary objectives were to assess morbidity, quality of life, and applied algorithms. BACKGROUND Breast-conserving therapy (BCT) has become the standard of care, and survival is now excellent. Consequently, the focus of BCT has increasingly shifted to cosmetic outcome, quality of life, and patient satisfaction. Nonetheless, excision of certain tumors still presents a considerable challenge. Specialized approaches combining oncological surgery and plastic surgery techniques are collectively referred to as OPBS. A summary of OPBS outcomes would facilitate decision-making and best treatment selection by both clinicians and patients. METHODS Using specific inclusion and exclusion criteria to analyze 2090 abstracts on the topic of OPBS published between 2000 and 2011, the authors evaluated each study with respect to design and outcomes. RESULTS A total of 88 articles were identified for potential inclusion and reviewed in detail by the lead authors. No randomized controlled trials were identified. Eleven prospective observational or comparative studies fulfilled inclusion criteria and were selected. In these studies, 80% to 93% of the tumors were invasive. Tumor-free resection margins were observed in 78% to 93%, resulting in a 3% to 16% mastectomy rate. Local recurrence was observed in 0% to 7% of the patients. Good cosmetic outcome was obtained in 84% to 89% of patients. However, most studies showed significant weaknesses including lack of robust design and important methodological shortcomings, negatively influencing generalizability. CONCLUSIONS This systematic review reveals that current evidence supporting the efficacy of OPBS is based on poorly designed and underpowered studies. Given the increasing importance and application of OPBS, there is a pressing need for robust comparative studies, including both randomized controlled trials and well-designed, multicenter prospective longitudinal studies.

Abstract
INTRODUCTION The use of conservative surgery combined with whole-breast irradiation (WBI) has been established as a valid alternative to mastectomy for the management of early-stage breast cancer. The aim of this study was to compare dosimetric parameters of the planning target volume(PTV) and organs at risk (OARs) between conventional radiation therapy (CR), 3-D conformal radiation therapy (3DCRT), and direct machine parameter optimisation intensity-modulated radiation therapy (DMPO-IMRT) after breast-conserving surgery. METHODS AND MATERIALS Computed tomography (CT) scans from 20 patients (13 left-sided and 7 right-sided) previously treated with T1N0 or ductal carcinoma were selected for this dosimetric planning study. We designed CR, 3DCRT and DMPO-IMRT plans for each patient. The prescribed dose was 50 Gy/2 Gy/25 f, 95% of PTV received the prescription dose. Doses were computed with a commercially available treatment planning system using convolution/superimposition (CS) algorithm. Plans were compared according to dose-volume histogram (DVH) analysis in terms of PTV homogeneity and conformity indices (HI and CI) as well as OARs dose and volume parameters. RESULTS Both the HI and CI of the PTV showed statistically significant difference between CR, 3DCRT and DMPO-IMRT with those of DMPO-IMRT were best (P < 0.05). Compared with CR, 3DCRT showed smaller exposed volumes of ipsilateral lung, contralateral breast and heart while DMPO-IMRT indicated larger exposed volumes of ipsilateral lung (except for V20 and V30), contralateral breast and heart. In addition, DMPO-IMRT demonstrated an increase of exposed volume of ipsilateral lung (except for V30), contralateral breast and heart compared with 3DCRT. CONCLUSIONS In WBI of breast cancer after conservative surgery, 3DCRT and DMPO-IMRT improved the homogeneity and conformity of the PTV compared with CR. Meanwhile, 3DCRT reduced the irradiated volumes of OARs at all dose levels listed in our study while DMPO-IMRT reduced the irradiated volumes of OARs in high-dose areas but increased the irradiated volumes of OARs in low-dose areas.

Prone whole-breast irradiation using three-dimensional conformal radiotherapy in women undergoing breast conservation for early disease yields high rates of excellent to good cosmetic outcomes in patients with large and/or pendulous breasts. Int J Radiat Oncol Biol Phys 2011; 83:821-8. [PMID: 22208973 DOI: 10.1016/j.ijrobp.2011.08.020] [Citation(s) in RCA: 43] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2011] [Revised: 08/04/2011] [Accepted: 08/24/2011] [Indexed: 11/16/2022]
Abstract
PURPOSE To report our institution's experience using prone positioning for three-dimensional conformal radiotherapy (3D-CRT) to deliver post-lumpectomy whole breast irradiation (WBI) in a cohort of women with large and/or pendulous breasts, to determine the rate of acute and late toxicities and, more specifically, cosmetic outcomes. We hypothesized that using 3D-CRT for WBI in the prone position would reduce or eliminate patient and breast size as negative prognostic indicators for toxicities associated with WBI. METHODS AND MATERIALS From 1998 to 2006, 110 cases were treated with prone WBI using 3D-CRT. The lumpectomy, breast target volumes, heart, and lung were contoured on all computed tomography scans. A dose of 45-50 Gy was prescribed to the breast volume using standard fractionation schemes. The planning goals were ≥95% of prescription to 95% of the breast volume, and 100% of boost dose to 95% of lumpectomy planning target volume. Toxicities and cosmesis were prospectively scored using the Common Terminology Criteria for Adverse Effects Version 3.0 and the Harvard Scale. The median follow-up was 40 months. RESULTS The median body mass index (BMI) was 33.6 kg/m(2), and median breast volume was 1396 cm(3). The worst toxicity encountered during radiation was Grade 3 dermatitis in 5% of our patient population. Moist desquamation occurred in 16% of patients, with only 2% of patients with moist desquamation outside the inframammary/axillary folds. Eleven percent of patients had Grade ≥2 late toxicities, including Grade 3 induration/fibrosis in 2%. Excellent to good cosmesis was achieved in 89%. Higher BMI was associated with moist desquamation and breast pain, but BMI and breast volume did not impact fibrosis or excellent to good cosmesis. CONCLUSION In patients with higher BMI and/or large-pendulous breasts, delivering prone WBI using 3D-CRT results in favorable toxicity profiles and high excellent to good cosmesis rates. Higher BMI was associated with moist desquamation, but prone positioning removed BMI and breast size as factors for poorer cosmetic outcomes. This series adds to the growing literature demonstrating that prone WBI may be advantageous in select patients.

Abstract
Most patients undergoing breast conservation therapy receive radiotherapy in the supine position. Historically, prone breast irradiation has been advocated for women with large pendulous breasts in order to decrease acute and late toxicities. With the advent of CT planning, the prone technique has become both feasible and reproducible. It was shown to be advantageous not only for women with larger breasts but in most patients since it consistently reduces, if not eliminates, the inclusion of heart and lung within the field. The prone setup has been accepted as the best localizing position for both MRI and stereotactic biopsy, but its adoption has been delayed in radiotherapy. New technological advances including image-modulated radiation therapy and image-guided radiation therapy have made possible the exploration of accelerated fractionation schemes with a concomitant boost to the tumor bed in the prone position, along with better imaging and verification of reproducibility of patient setup. This review describes some of the available techniques for prone breast radiotherapy and the available experience in their application. The NYU prone breast radiotherapy approach is discussed, including a summary of the results from several prospective trials.

Abstract
PURPOSE The efficacy of immediate breast reconstruction using a free dermal fat graft (FDFG) was evaluated clinically. PATIENTS AND METHODS A total of 22 breasts in 21 patients who underwent partial mastectomy for early breast cancer involving mainly the inner upper quadrant were enrolled in this study. The defect was reconstructed immediately by filling it with an autologous FDFG. At 6 months and 1, 2, 3, 4, and 5 years postoperatively, the width (horizontal length) and thickness (distance perpendicular to skin) of the FDFG on computed tomography (CT) scans were measured. Histologic samples from the implanted FDFG were collected by core needle biopsy (CNB). The correlations between clinical findings and volume of the FDFG on CT and the proportion of fatty tissue in the CNB were examined statistically. Cosmetic results were also evaluated. RESULTS On CT, the mean width of the FDFG was 95%, 81%, 79%, 73%, 68%, and 47% and the mean thickness were 125%, 121%, 120%, 115%, 104%, and 103% at 6 months, and 1-5 years postoperatively, respectively. In the CNB samples, the mean fatty tissue distribution was 76%, 63%, and 54% at 1 year, 1-4 years, and >4 years postoperatively, respectively. The percent change in the width of the FDFG at 6 months after the operation displayed a significant negative correlation with the postmenopausal period and a significant positive correlation with the maximum surgical margin. On CT, thickness was negatively correlated with the size of the resected breast tissue, and thickness of the implanted FDFG. No clinicopathologic factors or technical factors were related to FDFG outcome and the proportion of fat tissue in the CNB sample, except for axillary dissection. Nineteen of 21 patients had good to excellent cosmesis. CONCLUSION FDFG implanted into breast defects after partial mastectomy undergo mild resorption and degeneration to fibrous tissue, but most patients have good to excellent cosmesis.
