Sarcomatoid renal cell carcinoma (RCC) is an aggressive tumour with a poor prognosis. It is not a distinct histological entity, as it can be found in any subtype of renal cell carcinoma. The majority of cases will present with advanced or metastatic disease requiring systemic treatment.

Introduction: Ductal carcinoma (DCIS) accounts for 25% of newly diagnosed breast cancer cases with only 14%-53% developing into invasive ductal carcinoma (IDC), but currently overtreated due to inadequate accuracy of mammography. Subtypes of calcification, discernible from histology, has been suggested to have prognostic value in DCIS, while the lipid composition of saturated and unsaturated fatty acids may be altered in synthesis with potential sensitivity to the difference between DCIS and IDC. We therefore set out to examine calcification using ultra short echo time (UTE) MRI and lipid composition using chemical shift-encoded imaging (CSEI), as markers for histological calcification classification, in the initial step towards application.

Introduction: Congenital Hyperinsulinism (CHI) has not been previously studied in Ukraine. We therefore aimed to elucidate the genetics, clinical phenotype, histological subtype, treatment and long-term outcomes of Ukrainian patients with CHI.

Methods: Forty-one patients with CHI were recruited to the Ukrainian national registry between the years 2014-2023.

Purpose: Positive surgical margins (PSM) following partial nephrectomy (PN) for renal cell carcinoma (RCC) are a concern due to potential implications for recurrence and survival. This systematic review and meta-analysis assess the impact of PSM on recurrence rates and progression-free survival in RCC patients.

Methods: We conducted a systematic search of PubMed, Embase, Scopus, Cochrane, and Web of Science databases from inception through July 2024.

Background/aim: Ovarian cancer (OC) is one of the leading gynecological causes of death among women. The current standard treatment for OC is debulking surgery followed by platinum-based chemotherapy treatments; however, despite initial success to treatment many patients experience relapses. Currently, there are no available tests to predict sensitivity or resistance to chemotherapy.
