Choline PET/CT Features to Predict Survival Outcome in High Risk Prostate Cancer Restaging: A Preliminary Machine-Learning Radiomics Study

2020

Background Radiomic features are increasingly utilized to evaluate tumor heterogeneity in PET imaging but to date its role has not been investigated for Cho-PET in prostate cancer. The potential application of radiomics features analysis using a machine-learning radiomics algorithm was evaluated to select 18F-Cho PET/CT imaging features to predict disease progression in PCa. Methods We retrospectively analyzed high-risk PCa patients who underwent restaging 18F-Cho PET/CT from November 2013 to May 2018. 18F-Cho PET/CT studies and related structures containing volumetric segmentations were imported in the "CGITA" toolbox to extract imaging features from each lesion. A Machine-learning model h…

Intrinsic Subtypes and Gene Expression Profiles in Primary and Metastatic Breast Cancer.

2017

Biological changes that occur during metastatic progression of breast cancer are still incompletely characterized. In this study, we compared intrinsic molecular subtypes and gene expression in 123 paired primary and metastatic tissues from breast cancer patients. Intrinsic subtype was identified using a PAM50 classifier and χ2 tests determined the differences in variable distribution. The rate of subtype conversion was 0% in basal-like tumors, 23.1% in HER2-enriched (HER2-E) tumors, 30.0% in luminal B tumors, and 55.3% in luminal A tumors. In 40.2% of cases, luminal A tumors converted to luminal B tumors, whereas in 14.3% of cases luminal A and B tumors converted to HER2-E tumors. We ident…

204 Role of minimally invasive surgery versus open approach on the clinical and surgical outcome in patients with early stage uterine carcinosarcomas…

2020

Objectives The aim of this retrospective study was to compare surgical and survival outcome in only patients with early stage uterine carcinosarcomas (UCSs) managed by laparotomic surgery (LPT) versus minimally invasive surgery (MIS). Methods Data were retrospectively collected in 4 Italian different institutions. Inclusion criteria were: UCS diagnosis confirmed by the definitive histological examination, and stage I or II according to the FIGO staging system. Results Between August 2000 and March 2019, the data relative to 150 patients bearing UCSs were collected: of these, 82 were defined as early stage disease (stage I-II) based on the histological report at the primary surgery, and thus…
