Prediction of metastasis-free survival in patients with localized prostate adenocarcinoma using primary tumor and lymph node radiomics from pre-treatment PSMA-PET/CT scans.

Purpose: To predict metastasis-free survival (MFS) for patients with prostate adenocarcinoma (PCa) treated with androgen deprivation therapy (ADT) and external radiotherapy using clinical factors and radiomics extracted from primary tumor and node volumes in pre-treatment PSMA PET/CT scans.

Materials/methods: Our cohort includes 134 PCa patients (nodal involvement in 28 patients). Gross tumor volumes of primary tumor (GTVp) and nodes (GTVn) on CT and PET scans were segmented.

National survey of radiotherapy and androgen deprivation therapy strategies with PSMA-PET/CT integration in intermediate-risk prostate cancer: TROD 09-007 study.

Background: Intermediate-risk prostate cancer (IR-PC) represents a heterogeneous group requiring nuanced treatment approaches, and recent advancements in radiotherapy (RT), androgen deprivation therapy (ADT), and prostate-specific membrane antigen positron emission tomography (PSMA-PET/CT) imaging have prompted growing interest in personalized, risk-adapted management strategies. This study by the Turkish Society for Radiation Oncology aims to examine radiation oncologists' practices in managing IR-PC, focusing on RT and imaging modalities to identify trends for personalized treatments.

Methods: A cross-sectional survey was conducted among Turkish radiation oncologists treating at least 50 prostate cancer (PC) cases annually.

Predictive utility of Post-Treatment tumor apparent diffusion coefficient in High-Risk prostate cancer undergoing definitive Radiotherapy: A Long-Term outcome analysis.

Background: This study evaluated the prognostic value of post-treatment apparent diffusion coefficient (ADC) derived from diffusion-weighted magnetic resonance imaging (DW-MRI) in high-risk prostate cancer (PCa) patients treated with definitive radiotherapy (RT) and androgen deprivation therapy (ADT).

Materials And Methods: A retrospective cohort of 186 high-risk PCa patients treated between 2012 and 2023 was analyzed. All underwent pre- and post-treatment DW-MRI for staging, RT planning, and response assessment.

Investigation of Histamine, Physicochemical Quality, and Potential Health Risks in Various Canned Fish Products.

An investigation of the histamine presence in canned fish is crucial in terms of food safety and human health. The aim of this study was to investigate the levels of histamine, pH, and salt in various canned fish products consumed in Ankara, Türkiye. For this purpose, a total of 80 canned food samples (30 tuna, 30 sardine, and 20 anchovy samples) from different firms were analyzed for histamines using an enzyme-linked immunosorbent assay technique.
