Baker's clinical classification is adopted as the gold standard for grading complications related to silicone implants. Despite being widely used for this purpose, the classification has several limitations, highlighting subjectivity, reproducibility, and interobserver agreement. In this technical report, we aim to present the reasons for the inadequacy of the Baker classification for breast implants and the main factors contributing to false-negative results using recent theories of surface tension of fluids and gel bleeding...

PURPOSE: Breast brachytherapy (BB) represents an important radiation therapy modality in modern breast cancer treatments. Currently, BB is mainly used for accelerated partial breast irradiation (APBI), local boost after whole breast radiation therapy (WBRT), and as salvage re-irradiation after second lumpectomy (APBrl). Two multi-catheter interstitial brachytherapy (MIB) techniques can be offered: intra-operative (IOB) and post-operative (POB) brachytherapy. The aim of this article was to summarize current available data on these two different brachytherapy approaches for breast cancer...

BACKGROUND: Missing data can affect the representativeness and accuracy of survey results, and sexual health-related surveys are especially at a higher risk of nonresponse due to their sensitive nature and stigma. The purpose of this study was to evaluate the proportion of patients who do not complete the BREAST-Q Sexual Well-being relative to other BREAST-Q modules and compare responders versus nonresponders of Sexual Well-being. We secondarily examined variables associated with Sexual Well-being at 1-year...

The clinical data of 23 patients undergoing real-time echocardiography-guided infusion port implantation in the Breast Center of Tsinghua Changgung Hospital in Beijing from January to July 2021 were analyzed. The length of catheter insertion L1 was initially estimated using surface measurement method in all patients. Intraoperatively, transthoracic echocardiography was applied using the parasternal four-chamber view to visualize the catheter image within the right atrium, and the length of catheter insertion L2 was recorded under the guidance of echocardiography...

INTRODUCTION: Immediate breast reconstruction following mastectomy reduces perceptions of mutilation and femininity issues in oncological patients, but surgical complications should not delay chemotherapy. This study evaluated postsurgical complications in patients who underwent radical breast surgery followed by immediate reconstruction with latissimus dorsi myocutaneous flaps and silicone implants, along with resulting impacts in delaying chemotherapy. MATERIALS AND METHODS: This retrospective study utilized a prospectively maintained database...

BACKGROUND Endometriosis is a common cause of chronic pelvic pain among women globally. Pharmacological therapy for endometriosis includes non-steroidal anti-inflammatory drugs (NSAIDs) and hormonal contraceptives, while surgical therapy often involves either laparoscopic excision and ablation of endometriosis implants or open surgery. Surgical therapy is one of the mainstays of treatment especially for extrapelvic endometriomas. However, little guidance exists for the treatment of non-palpable or intermittently palpable lesions of this nature...

BACKGROUND: This pioneering study evaluates the safety, efficacy, and Aesthetic outcomes of Ergonomix2 Motiva Ergonomic Implants in breast augmentation. It aims to assess their capability to offer more natural touch and dynamics, delineate the learning curve for surgical techniques, and examine their safety profile compared to Ergonomix1 implants. MATERIALS AND METHODS: A prospective cohort study was conducted, comparing 31 patients who received Ergonomix2 implants with a control group of 51 patients with Ergonomix1 implants...

BACKGROUND: Implants and DIEP flaps have different outcomes regarding postoperative breast sensation. When compared to the preoperative healthy breast, implant-based breast reconstruction (IBBR) negatively influences postoperative breast sensation. However, it is currently unknown whether a prior IBBR also influences postoperative sensation of a replacing DIEP flap. The goal of this cohort study is to evaluate the influence of an IBBR on the postoperative sensation of a replacing DIEP flap...

BACKGROUND: Nanotextured implants, an innovation in implant technology, are designed to enhance tissue interaction, reduce inflammation, and mitigate complications compared to traditional implants. OBJECTIVES: The aim of the study was to evaluate the aesthetic potential and safety profile of nanotextured breast implants in breast augmentation from a single-surgeon experience. METHODS: This prospective cohort study included 1,000 patients who underwent breast augmentation with nanotextured implants...

OBJECTIVE: We have studied the use of polymethyl methacrylate (PMMA) as an alternative biopsy marker that is readily detectable with ultrasound Doppler twinkling in cases of in vitro, ex vivo, or limited duration in vivo settings. This study investigates the long-term safety and ultrasound Doppler twinkling detectability of a PMMA breast biopsy marker following local perturbations and different dwell times in a 6-mo animal experiment. METHODS: This study, which was approved by our Institutional Animal Care and Use Committee, involved three pigs and utilized various markers, including PMMA (Zimmer Biomet), 3D-printed, and Tumark Q markers...

Evading recognition of immune cells is a well-known strategy of tumors used for their survival. One of the immune evasion mechanisms is the synthesis of kynurenine (KYN), a metabolite of tryptophan, which suppresses the effector T cells. Therefore, lowering the KYN concentration can be an efficient antitumor therapy by restoring the activity of immune cells. Recently, kynureninase (KYNase), which is an enzyme transforming KYN into anthranilate, was demonstrated to show the potential to decrease KYN concentration and inhibit tumor growth...

For women undergoing mastectomy, breast reconstruction can be performed by using implants or autologous tissue flaps. Mastectomy options include skin- and nipple-sparing techniques. Implant-based reconstruction can be performed with saline or silicone implants. Various autologous pedicled or free tissue flap reconstruction methods based on different tissue donor sites are available. The aesthetic outcomes of implant- and flap-based reconstructions can be improved with oncoplastic surgery, including autologous fat graft placement and nipple-areolar complex reconstruction...

BACKGROUND: Augmentation mastopexy remains a challenging procedure. The goal is to achieve correction of breast ptosis whilst adding implant volume, and avoid complications of premature waterfall deformity, bottoming out and further revision surgery, particularly when using smooth implants. We aim to describe and evaluate a technique to reduce implant malposition in augmentation mastopexy. METHODS: This is a technical description and retrospective review of a single surgeons' cases from 2019 to 2022 of all patients who underwent 1 stage subpectoral breast augmentation mastopexy with the inferolateral pectoralis sling...

BACKGROUND: Postmastectomy radiation therapy (PMRT) is a mainstay in the adjuvant treatment of node-positive breast cancer, but it poses risks for women with breast reconstruction. Multi-beam intensity-modulated radiation therapy (IMRT) improves dose conformality and homogeneity, potentially reducing complications in breast cancer patients with implant-based reconstruction. To investigate this hypothesis, we conducted a single-arm phase II clinical trial of breast cancer patients who underwent mastectomy/axillary dissection and prosthesis-based reconstruction...

INTRODUCTION: When planning for breast augmentation, it is important to consider not only implant choice, surgical technique and patient desires, but also the chest wall shape and deformities or irregularities, which remain often underestimated. They can be responsible for implant malposition and breast asymmetry after augmentation. Chondrocostal junction prominence is a minor but frequent chest wall deformity. The aim of this study is to report a new technique for sculpturing isolated chondrocostal prominence deformities in patients undergoing breast augmentation...

The aberrant activation of HER2 has a pivotal role in bone metastasis implantation and progression in several tumor types, including prostate cancer (PC). Trastuzumab and other anti-HER2 therapies, such as lapatinib, have been used in human breast cancer HER2 positive. Although HER2 overexpression has been reported in PC, anti-HER2 therapy response has revealed conflicting results. We investigated the potential of lapatinib in inhibiting cell migration and inducing apoptosis in two human (LNCaP and PC3) and two canine PC cell lines (PC1 and PC2)...

BACKGROUND: Many factors influence a patient's decision to undergo autologous versus implant-based breast reconstruction, including medical, social, and financial considerations. This study aims to investigate differences in out-of-pocket and total spending for patients undergoing autologous and implant-based breast reconstruction. METHODS: The IBM MarketScan Commercial Databases were queried to extract all patients who underwent inpatient autologous or implant-based breast reconstruction from 2017 to 2021...

BACKGROUND: Breast reconstruction methods vary based on factors such as medical history, breast size, and personal preferences. However, disparities in healthcare exist, and the role race plays in accessing to different reconstruction methods is unclear. This study aimed to investigate the influence of race and/or ethnicity on the type of breast reconstruction chosen. METHODS: This retrospective cohort study analyzed the University of Pittsburgh Medical Center Magee Women's Hospital database, including patients who underwent breast cancer surgery from 2011 to 2022...
