ntroduction: Breast Cancer is the most frequently occurring cancer in Canadian women [1]. The standard of care normally involves breast conserving surgery and radiation therapy followed by breast reconstruction surgery. For successful breast reconstruction, the total volume loss must be accounted for. Unfortunately, the volume excised during surgery generally does not reflect total breast volume loss, for example, radiation therapy is known to cause volume loss of the breast [2]. Our goal is to provide the software and workflow necessary to calculate the breast volume using a non-invasive technique. By calculating and comparing the breast volume of the patient before undergoing reconstruction surgery to the baseline volume will help surgeon’s better estimate how much tissue needs to be replaced. Methods: A 3D surface scan of the patient’s chest is obtained. The scan is then imported into 3D Slicer where modules are used to isolate the target breast and calculate the volume . Results: The method provided to calculate breast volume is feasible using 3D Slicer and only requires one surface scan from the patient. The ground truth breast volume of the mannequin was 164mL with a standard deviation of 4.1ml (n=5). The volume of the mannequin’s breast was calculated using the workflow provided, the mean calculated volume was 160.8mL and the standard deviation was 4.7ml (n=4). Conclusion: Using a 3D surface scanner provides a non-invasive and quick way to calculate breast volume. This initial validation suggests this system may be accurate enough to aid the surgeon in the reconstruction process. References [1] Canadian Breast Cancer Society. (2015).

The Impact

Introduction: Breast cancer is the most common malignancy among women, and is usually treated surgically. Mastectomy has a great influence on the mental and physical condition of women. Breast reconstruction offers them a chance to improve their quality of life (QOL) and self-image.The main aim of the study was to gain knowledge about the impact of breast reconstruction on the QOL of women following mastectomy, and an analysis of the QOL after breast reconstruction, in the context of prosthesis effect assessment.Materials and methods: The study comprised 100 women following breast reconstructive surgery involved in 1 of the 7 “Amazon Clubs” (post-mastectomy women’s associations) in the West Pomeranian Voivodeship, northwest Poland. The study was based on the author’s questionnaire, and a shortened standardized version of the World Health Organization Quality of Life-BREF (WHOQOL-BREF) questionnaire. Statistical calculations were performed with StatSoft Statistica v10 software, adopting a significance level of p < 0.05.Results: The women who decided to have breast reconstruction surgery, noticed improved well-being (67%) and experiencedan increase in self-confidence (61%). The vast majority ofthe patients surveyed (93%) were satisfied with the effectof the prosthesis. Statistically significant differences in QOL were observed in the following spheres: rest and sleep, work capacity, negative feelings, and financial resources (p < 0.05) in relation to the evaluation of the prosthesis effect.Conclusions: 1. Breast reconstruction has a positive influence on improvements in well-being, increasing self-esteem, and the assessment of a more attractive appearance in women of all ages. 2. Breast reconstruction surgery has a positive impact on QOL and health in the physical, psychological, and environmental domains, especially in the women who are satisfied with the effects of the surgery. 3. A negative assessment of the breast reconstruction effect has an adverse influence on QOL. Identifying the factors affecting dissatisfaction with the post-operative outcome is crucial for a complete understanding of the subject, and for implementing measures aimed at improving the QOL of these women.Keywords: quality of life; mastectomy; breast cancer; breast reconstruction; breast surgery.

Reconstruction Surgery

Breast reconstruction surgery means using autologous tissue grafts and breast prosthesis to rebuild chest wall deformities and the absence of breast caused by post mastectomy, which are possibly due to burns, trauma, infections, congenital dysplasia and sex reassignment surgery etc., with the prevalence of unilateral breast reconstruction. After attempting to carry out breast reconstruction with latissimus dorsi, many surgeons constantly improved, designed, and modified multiple forms of operation programs and thus promote increasing improvement in repair and reconstruction of the breast after breast reduction surgery and mastectomy for breast cancer [1] Currently, breast reconstruction after breast cancer surgery is just in the early stage while it has occupied an important position in developed countries,therefore, the knowledge of breast reconstruction needs to be enhanced and publicized in our country. Some data show the quality of life in patients following breast reconstruction surgery is significantly higher than that in patients undergoing lumpectomy plus radiotherapy or simple mastectomy. More and more patients pursue breast reconstruction after mastectomy for breast cancer. Breast reconstruction is roughly divided into lost chest wall skin repair, hemispherical breast reconstruction, anterior axillary fold repair, plastic surgery for subclavian depression, nipple and areola reconstruction and asymmetrical breast repair. In the reconstruction of breasts, it is necessary to endeavor to make the rebuilt breast symmetrical to the healthy side so that future adjustment will be simple and easily feasible.

Abstract Background: The surgical treatment of breast cancer involves various psychological consequences, which differ according to individual characteristics. Our study aimed to identify the role that cognitive schemas had in triggering anxiety and depressive symptoms in patients diagnosed with breast cancer that underwent oncological and plastic surgery treatment. Methods: 64 female patients, diagnosed with breast cancer from an Oncology and Plastic Surgery Hospital, were selected to participate in this study between March-June 2018. They were divided into two groups: I. 28 patients who underwent mastectomy surgery; II. 36 patients, who required mastectomy and, subsequently, also chose to undergo breast reconstruction surgery. For the purposes of evaluating a possible change in mental health status, we employed two assessment scales: the Young Cognitive Schema Questionnaire - Short Form 3 (YSQ-S3) and the Romanian version of the Depression Anxiety Stress Scale – 21 (DASS-21R). Results: Participants who underwent mastectomy and subsequent breast reconstruction surgery employed cognitive schemas that did not generate symptoms of depression or anxiety. In contrast, the cognitive schemas found in women who refused reconstructive breast surgery were significantly correlated with the presence of anxiety-depressive symptoms.The cognitive schema domain of ‘disconnection and rejection' correlated uncertainly with the presence of anxiety-depressive symptoms for the group with breast reconstruction (Spearman's r= 0.091, p = 0.644), while for the other group the correlation was moderate-strong (Spearman’s r= 0.647, p < 0.01). Negative emotional schemas were significantly correlated with the presence of anxiety-depressive symptoms (Spearman's r= 0.598, p < 0.01) in the group of participants without reconstructive surgery. Conclusion: A correct identification of dysfunctional cognitive schemas and coping mechanisms at the commencement of the combined treatment in breast cancer patients could serve as an indicator for the evolution of their mental health, therefore assisting professionals in establishing the most suitable psychological, psychotherapeutic and psychiatric intervention plan.

e12596 Background: Randomized trials in stage 0-II breast cancer have proven that APBI given via HDR implant in 5 days is equivalent to whole breast External Radiation Therapy (XRT) given in 5-6 weeks in regard to breast tumor local recurrence (LR). However, complications have been significant. Recently APBI using non-invasive IMRT given in 5 fractions has been shown in another randomized trial to be equivalent to XRT in 6 weeks, with respect to LR. IMRT was superior in regard to acute effects, late effects, and cosmesis. In the randomized clinical trial of APBI IMRT, the Clinical Target Volume (CTV) was defined by the injection of individual fiducial markers bordering the surgical cavity. At our institution, we have used the Biozorb fiducial system to localize the CTV for IMRT. We sought to confirm the APBI IMRT results with this simpler less labor intensive fiducial placement system. Methods: Between 2017 and 2020, 135 patients have undergone SBRT targeted to a Biozorb defined CTV with the walls of the surgical cavity sewn to the Biozorb device. Eligible patients were older than age 40, had tumor sizes < 3 cm, negative surgical margins, and negative sentinel node dissections. SBRT dose was 30 Gy given in 5 fractions. Dose Constraints were as follows: V-30 Gy < 105%, Ipsilateral Breast V-15 Gy < 50%, Ipsilateral Lung V-10 Gy < 20%, Contralateral Lung V-5 Gy < 10%, Heart V-3 Gy < 20%, Contralateral Breast Dmax < 2 Gy and Skin Dmax < 27 Gy. The Planning Target Volume (PTV) ranged from 27 to 355 cc with a median of 80 cc. PTV = CTV + 1-2 cm. Results: Follow-up ranged from 1-26 months with a median of 12 months. LR has been 0% (0/135). There have been no skin reactions or seromas. Infection has occurred in one patient (0.7%). Three (2.2%) patients developed pain around the Biozorb site. This resolved within 2 days on a short course of steroids in all cases. Cosmetic results as rated by the Surgeon, Radiation Oncologist, and Nurse, were rated excellent in 98.5% (133/135) of cases. Conclusions: Non-invasive APBI with SBRT given qd over 5 days targeted to Biozorb has resulted in LR, complications, and cosmetic results which compare favorably to invasive APBI given bid with HDR implant. At last follow-up, there have been no LR, skin reactions, or significant complications. Cosmesis has been excellent in 98.5% of patients.

Breast reconstruction after breast cancer is an emotional subject for women. Consequently, the correct timing and surgical procedure for each individual woman are important. In general, heterologous or autologous reconstructive procedures are available, both having advantages and disadvantages. Breast size, patient habitus, and previous surgeries or radiation therapy need to be considered, independent of the chosen procedure. New surgical techniques, refinement of surgical procedures, and the development of supportive materials have increased the general patient collective eligible for breast reconstruction. This review highlights the different approaches to immediate breast reconstruction using autologous or heterologous techniques.
