Validation analysis of the novel imaging-based prognostic radiomic signature in patients undergoing primary surgery for advanced high-grade serous ovarian cancer (HGSOC).

Background: Predictive models based on radiomics features are novel, highly promising approaches for gynaecological oncology. Here, we wish to assess the prognostic value of the newly discovered Radiomic Prognostic Vector (RPV) in an independent cohort of high-grade serous ovarian cancer (HGSOC) patients, treated within a Centre of Excellence, thus avoiding any bias in treatment quality.

Methods: RPV was calculated using standardised algorithms following segmentation of routine preoperative imaging of patients (n = 323) who underwent upfront debulking surgery (01/2011-07/2018).

Response evaluation after neoadjuvant therapy: evaluation of chemotherapy response score and serological and/or radiological assessment of response in ovarian cancer patients.

Purpose: The chemotherapy response score (CRS) is a histopathological tool to evaluate response to neoadjuvant chemotherapy (NACT) in high-grade serous ovarian cancer (OC). We critically evaluated the clinical value of CRS and compared its predictive power to standard serological (CA125) and radiological response.

Methods: A retrospective analysis of 277 OC patients, who received primary chemotherapy, was performed.

Pattern and impact of metastatic cardiophrenic lymph nodes in advanced epithelial ovarian cancer.

Background: Cardiophrenic lymph nodes (CPLN) define FIGO stage IVB disease. We evaluate the pattern of CPLN metastases, their prognostic impact and the potential role of CPLN resection in patients with epithelial ovarian cancer (EOC).

Methods: Analysis of 595 consecutive patients with EOC treated in the period 01/2011-05/2016.

Skeletal Muscle Attenuation (Sarcopenia) Predicts Reduced Overall Survival in Patients with Advanced Epithelial Ovarian Cancer Undergoing Primary Debulking Surgery.

Background: Sarcopenia was reported as a prognostic factor in cancer patients. Using computed tomography (CT), we analyzed the impact of sarcopenia on overall survival (OS) in patients with advanced epithelial ovarian cancer (EOC) after primary debulking surgery (PDS).

Methods: Preoperative CT scans of consecutive EOC patients (n = 323) were retrospectively assessed for skeletal muscle index (SMI) and muscle attenuation (MA; Hounsfield units [HU]).

Surgical management of cardiophrenic lymph nodes in patients with advanced ovarian cancer.

Objective: Debulking surgery for advanced ovarian cancer does not routinely include opening of the thorax. Even systematic lymphadenectomy does not commonly extend to lymph nodes above the diaphragm. We evaluated the outcome of systematic resection of suspicious cardiophrenic lymph nodes detected on preoperative CT-scan in patients with advanced epithelial ovarian cancer (EOC).

Magnetic resonance coronary angiography with Vasovist: in-vivo T1 estimation to improve image quality of navigator and breath-hold techniques.

The purpose of the study was to estimate T1 values of blood and myocardium after a single injection of Vasovist and to assess Vasovist for magnetic resonance coronary angiography (MRCA). For all exams 0.05 mmol/kg of Vasovist was injected.

Assessment of left ventricular parameters using 16-MDCT and new software for endocardial and epicardial border delineation.

Objective: The purpose of our study was to quantify left ventricular function and mass derived from retrospectively ECG-gated 16-MDCT coronary angiography data sets using a new analysis software based on automatic contour detection in comparison to corresponding standard of reference measurements acquired with MRI.

Subjects And Methods: Multiplanar reformations in the short-axis orientation were calculated from axial contrast-enhanced CT images in 18 patients (men, 15; women, three; age range, 38-70 years; mean, 57.4 +/- 10.

Coronary artery calcium score: influence of reconstruction interval at 16-detector row CT with retrospective electrocardiographic gating.

In 30 patients, Agatston and volumetric scores were assessed by using retrospectively gated multi-detector row computed tomography (CT). For each patient, 10 data sets were created at different times and were evenly spaced throughout the cardiac cycle. For each reconstruction, patients were assigned a percentile that described the level of cardiovascular risk.

MRI in coronary artery disease.

Diagnosis of coronary artery disease (CAD) is a major challenge for medical imaging, because CAD is the leading cause of death in developed nations. Several non-invasive tests are used in clinical routine for the detection of CAD. However, due to limited sensitivity and specificity, the reliable diagnosis as well as the exclusion of CAD can only be established by catheter angiography.
