: There are conflicting data regarding the detection rate of high-risk uterine sarcoma (HRUS) by endometrial biopsy. In addition, there are no studies in the literature on its impact on the chosen surgical approach and survival. : This study includes 415 patients with HRUS.

BACKGROUND Abdominal pregnancy is a rare form of extrauterine pregnancy that usually results in a poor outcome; it is associated with serious fetal and maternal morbidity. The diagnosis of advanced abdominal pregnancy is sometimes challenging and should be identified early, at a routine antenatal examination. There are still no evidence-based management strategies for late abdominal pregnancy.

Purpose: The use of tissue adhesive instead of a drain following mastectomy was a point of interest for many breast surgeons. Postoperative formation of multiple unusual sonographic lesions was observed in patients that underwent mastectomy with TissuGlu. The aim of this study was to describe the sonographic features of these lesions and, when possible, to examine them histologically.

Background: Accurate preoperative molecular and histological risk stratification is essential for effective treatment planning in endometrial cancer. However, inconsistencies between pre- and postoperative tumor histology have been reported in previous studies. To address this issue and identify risk factors related to inaccurate histologic diagnosis after preoperative endometrial evaluation, we conducted this retrospective analysis.

BACKGROUND Leiomyosarcomas of the vulva (VLMS) are very rare among gynecological malignancies, with a lack of knowledge on clinical presentation, prognosis, and therapeutic management. CASE REPORT The database of the German Clinical Center of Competence for Genital Sarcomas and Mixed Tumors in Greifswald (DKSM) was reviewed between the years 2010 and 2020. A total of 8 cases of VLMS were retrieved and analyzed retrospectively.

Objectives: We evaluated whether lesion-to-fat ratio measured by shear wave elastography in patients with Breast Imaging Reporting and Data System (BI-RADS) 3 or 4 lesions has the potential to further refine the assessment of B-mode ultrasound alone in breast cancer diagnostics.

Methods: This was a secondary analysis of an international diagnostic multicenter trial (NCT02638935). Data from 1288 women with breast lesions categorized as BI-RADS 3 and 4a-c by conventional B-mode ultrasound were analyzed, whereby the focus was placed on differentiating lesions categorized as BI-RADS 3 and BI-RADS 4a.

Background: Uterine leiomyosarcoma (LMS) is a rare entity amongst malignant gynaecological tumours and is mostly diagnosed after surgery for benign leiomyoma (LM) of the uterus. As minimal invasive surgery is widely used, the morcellation of LM and the uterus is rather common. As there is little known about the impact of the morcellation of LMS on local and distant metastases, as well as overall survival, we carried out a large-scale retrospective study.

Background: Breast ultrasound identifies additional carcinomas not detected in mammography but has a higher rate of false-positive findings. We evaluated whether use of intelligent multi-modal shear wave elastography (SWE) can reduce the number of unnecessary biopsies without impairing the breast cancer detection rate.

Methods: We trained, tested, and validated machine learning algorithms using SWE, clinical, and patient information to classify breast masses.

Article Synopsis
  • AI algorithms for medical image analysis showed they can perform as well as human readers in breast cancer diagnosis but need to incorporate multiple data sources for better accuracy.
  • * In a study with 1288 women, both human experts and AI using ultrasound data alone had similar success rates in diagnosing breast masses.
  • * However, when integrating additional clinical and demographic information, AI algorithms performed better, yet both still lagged behind traditional routine diagnosis methods.

Background: Shear wave elastography (SWE) and strain elastography (SE) have shown promising potential in breast cancer diagnostics by evaluating the stiffness of a lesion. Combining these two techniques could further improve the diagnostic performance. We aimed to exploratorily define the cut-offs at which adding combined SWE and SE to B-mode breast ultrasound could help reclassify Breast Imaging Reporting and Data System (BI-RADS) 3-4 lesions to reduce the number of unnecessary breast biopsies.

Purpose:  In this prospective, multicenter trial we evaluated whether additional shear wave elastography (SWE) for patients with BI-RADS 3 or 4 lesions on breast ultrasound could further refine the assessment with B-mode breast ultrasound for breast cancer diagnosis.

Materials And Methods:  We analyzed prospective, multicenter, international data from 1288 women with breast lesions rated by conventional 2 D B-mode ultrasound as BI-RADS 3 to 4c and undergoing 2D-SWE. After reclassification with SWE the proportion of undetected malignancies should be < 2 %.

Aim: This research compares postoperative complication rates with Strattice™, SERAGYN BR, and TiLOOP Bra interposition devices for subpectoral implant placement after skin or nipple sparing mastectomy.

Patients And Methods: 188 breast reconstructions in 157 patients after primary (n=96), secondary (n=71), or prophylactic (n=21) surgery were analyzed regarding major and minor complications.

Results: With acellular dermal matrix (ADM) Strattice™, 27.

Aim: Quality of life and patient satisfaction after subpectoral breast reconstruction with meshes or acellular dermal matrices (ADM) and implants were assessed using the BreastQ questionnaire to investigate a potential influence of the materials on these parameters.

Patients And Methods: The BreastQ questionnaire was completed by 121 patients, who had received material-assisted, heterologous, subpectoral breast reconstruction between 2010 and 2018.

Results: Answers were similar independent of the reconstruction materials used.

Background/aim: Synthetic meshes (SMs) and acellular dermal matrices (ADMs) are used in reconstructive breast surgery. In the absence of prospective comparative studies, the identification of differences relies on retrospective analyses.

Patients And Methods: Our analysis focused on the impact of pre- and postoperative radiotherapy (RTX) and material-related differences.

Background/aim: The influence of a polyurethane-based tissue adhesive (TissuGlu®) on common complications following breast surgery was investigated.

Patients And Methods: Within a Randomized-Controlled-Trial 70 women (n=35 TissuGlu®, n=35 drain) underwent a mastectomy with or without sentinel lymph node excision (SLNE), followed by a 90-day postoperative follow-up.

Results: Postoperative interventions: Non-inferiority of the application of TissuGlu® was seen.

Background/aim: The study aimed at investigating the correlation between ductoscopic and histopathological findings and clarify whether the former allow for accurate prediction of malignancy.

Patients And Methods: The prospective national multi-center study covered a sample of 224 patients with pathologic nipple discharge. A total of 214 patients underwent ductoscopy with subsequent extirpation of the mammary duct.
