    Abstract Cancer is increasingly recognized as an extraordinarily heterogeneous disease featuring an intricate mutational landscape and vast intra- and intertumor variability on both genetic and phenotypic levels. Prostate cancer (PCa) is the second most prevalent malignant disease among men worldwide. A single metabolic program cannot epitomize the perplexing reprogramming of tumor metabolism needed to sustain the stemness of neoplastic cells and their prominent energy-consuming functional properties, such as intensive proliferation, uncontrolled growth, migration, and invasion. In cancerous tissue, lipids provide the structural integrity of biological membranes, supply energy, influence the regulation of redox homeostasis, contribute to plasticity, angiogenesis and microenvironment reshaping, mediate the modulation of the inflammatory response, and operate as signaling messengers, i.e., lipid mediators affecting myriad processes relevant for the development of the neoplasia. Comprehensive elucidation of the lipid metabolism alterations in PCa, the underlying regulatory mechanisms, and their implications in tumorigenesis and the progression of the disease are gaining growing research interest in the contemporary urologic oncology. Delineation of the unique metabolic signature of the PCa featuring major aberrant pathways including de novo lipogenesis, lipid uptake, storage and compositional reprogramming may provide novel, exciting, and promising avenues for improving diagnosis, risk stratification, and clinical management of such a complex and heterogeneous pathology.

    Abstract Seminomas are most commonly diagnosed in clinical stage I (CSI). After orchiectomy, approximately 15% of patients in this stage have subclinical metastases. Adjuvant radiotherapy (ART) delivered to the retroperitoneum and ipsilateral pelvic lymph nodes has been the mainstay of treatment for many years. Although highly efficient, with long-term cancer-specific survival (CSS) rates approaching almost 100%, ART is associated with considerable long-term consequences, particularly cardiovascular toxicity and increased risk of secondary malignancies (SMN). Therefore, active surveillance (AS) and adjuvant chemotherapy (ACT) were developed as alternative treatment options. While AS prevents patient overtreatment, it is associated with strict follow-up regimens and increased radiation exposure due to repeated imaging. Due to equivalent CSS rates to ART, and lower toxicity, one course of adjuvant carboplatin presents the cornerstone of chemotherapy for CSI patients. CSS is almost 100% for patients with CSI seminoma, regardless of the chosen treatment option. Therefore, a personalized approach in treatment selection is preferred. Currently, routine radiotherapy for CSI seminoma patients is no longer recommended. Instead, it should be reserved for patients who are unfit or unwilling for AS or ACT. Identification of prognostic factors for disease relapse allowed for the development of risk-adapted treatment strategy and stratification of patients in low-risk and high-risk groups. Although risk-adapted policy needs further validation, surveillance is currently recommended in low-risk patients, while ACT is reserved for patients with a higher risk of relapse.

    Abstract This narrative review summarizes epidemiological studies on breast cancer and prostate cancer with an overview of their global incidence distribution to investigate the relationship between these diseases and diet. The biological properties, mechanisms of action, and available data supporting the potential role of isoflavones in the prevention of breast cancer and prostate cancer are discussed. Studies evaluating the effects of isoflavones in tissue cultures of normal and malignant breast and prostate cells, as well as the current body of research regarding the effects of isoflavones attained through multiple modifications of cellular molecular signaling pathways and control of oxidative stress, are summarized. Furthermore, this review compiles literature sources reporting on the following: (1) levels of estrogen in breast and prostate tissue; (2) levels of isoflavones in the normal and malignant tissue of these organs in European and Asian populations; (3) average concentrations of isoflavones in the secretion of these organs (milk and semen). Finally, particular emphasis is placed on studies investigating the effect of isoflavones on tissues via estrogen receptors (ER).

    Abstract Objective: We aimed to assess the prognostic value of De Ritis ratio on oncological outcomes in patients suffering from urothelial bladder cancer and undergoing radical cystectomy (RC).
    Patients and methods: Analytical cohort comprised a single-center series of 367 patients treated between January 2015 and December 2018. Patients were classified into two groups based on De Ritis ratio (<1.3 [normal] vs. ≥1.3 [high]). Along with the Kaplan-Meier survival probability, cox proportional hazard regression models were used.
    Results: A total of 299 patients were included, 60.5% of them having a De Ritis ratio of <1.3% and 39.5% with a De Ritis ratio of ≥1.3. Preoperative increased De Ritis ratio was associated with age (p = 0.001), gender (p = 0.044), cancer-related death (p = 0.001), overall death (p = 0.001), and tumor stage (p = 0.001). Multivariate analysis implied that preoperative De Ritis ratio was a significant independent prognosticator of overall survival (HR 0.461; 95% CI 0.335-0.633; p < 0.001) and CSS (HR 0.454; 95% CI 0.330-0.623; p < 0.001). Only tumor stage (HR 1.953; 95% CI 1. 106-3.448; p = 0.021) was independently associated with recurrence-free survival (RFS). De Ritis ratio was not independently associated with RFS in multivariate analyses. During the follow up, a total of 198 (66.2%) patients died, including 173 (57.9%) from BC, 5-year CSS was 45.8%.
    Conclusions: De Ritis ratio is an independent prognostic factor of cancer specific and overall survival in patients treated with RC for urothelial BC. RC patients may benefit from the use of the De Ritis ratio as a valid predictive biomarker.

    Abstract In contemporary clinical practice, biomarkers are indispensable in the assessment and management of oncological patients. Although established serum tumor markers (beta human chorionic gonadotropin (bHCG), alpha fetoprotein (AFP), and lactate dehydrogenase (LDH)) have an indisputably important role in the management of patients with testicular cancer (TC), the application of these tumor markers may be accompanied with certain limitations, implying the need for additional biomarkers. Contrary to TC, there is a lack of established serological biomarkers for penile cancer (PC) and the management of this urological malignancy is based on multiple clinicopathological parameters. Therefore, the identification and rigorous analytical and clinical validation of reliable biomarkers are considered pivotal for improving PC management. Inflammation may be associated with all stages of oncogenesis, from initial neoplastic transformation to angiogenesis, tissue invasion, and metastasis. Accordingly, an array of inflammation-related indices have gained increasing attention as emerging predictors of oncological outcomes. The clinical usefulness of systemic inflammation markers was reported in many urological and non-urological malignancies. The aim of this narrative review is to summarize current scientific data regarding the prognostic and predictive significance of systemic inflammation markers in TC and PC patients.

    Abstract Background: Since earlier research suggested a link between preoperative thrombocytosis and poor oncological outcomes in several cancers, the significance of platelet count abnormalities in bladder carcinoma (BC) demands for further investigation.
    Objective: To assess the prognostic value of preoperative thrombocytosis (PTC) on survival in patients with bladder carcinoma treated by radical cystectomy (RC).
    Patients and methods: Analytical cohort comprised a single-center series of 299 patients who underwent RC for bladder carcinoma was evaluated. A platelet count beyond the threshold of 400 × 10
    Results: Twenty-eight (9.4%) patients had preoperative thrombocytosis. PTC was associated with gender, tumor stage, tumor grade, lymphovascular invasion, hydronephrosis, anemia (p < 0.001), and hypoalbuminemia (p < 0.001). Preoperative thrombocytosis was strongly linked to worse overall survival (OS) (p = 0.002), and cancer specific survival (CSS) (p = 0.004), according to the Kaplan-Meier method. Throughout the follow-up, a total of 198 (66.2%) patients died, including 170 (56.9%) from BC. For this study population 5-year CSS was 45.8%. Preoperative thrombocytosis was not independently associated with OS (HR 1.168; 95% CI 0.740-1.844; p = 0.504) or CSS (HR 1.060; 95% CI 0.649-1.730; p = 0.816) in multivariate Cox regression analysis. Only tumor stage (HR 2.558; 95% CI 1.675-3.908; p < 0.001), hydronephrosis (HR 1.614; 95% CI 1.173-2.221; p = 0.003), lymph node metastasis (HR 1.555; 95% CI 1.076-2-2.248; p = 0.019), anemia (HR 1.454; 95% CI 1.034-2.046; p = 0.032) and ASA grade (HR 1.375; 95% CI 1.006-1.879; p = 0.046) were independently associated with CSS.
    Conclusions: In a single-center study of consecutive patients who underwent radical cystectomy for bladder cancer, preoperative thrombocytosis was unable to predict outcomes.

    Abstract There are limited data regarding the significance of multifocality in testicular cancer patients. This study evaluated the relationship between multifocality and clinicopathological features determined at the time of radical orchiectomy. The study involved 280 consecutive patients who underwent radical orchiectomy between 2018 and 2023. Multifocality was defined as a distinct tumor focus characterized by a group of malignant cells > 1 mm, clearly differentiated from the primary tumor mass. Uni- and multivariate logistic regression analyses were employed to investigate the association between multifocality and histopathological parameters along with potential risk factors for clinical stages II + III. Multifocality was identified in 44 (15.7%) patients. Significantly smaller primary tumors were observed in subjects with multifocality (20.0 mm vs. 30.0 mm,

    Abstract Background: The aim of this work was to evaluate the prognostic potential of preoperative thrombocytosis for recurrence-free survival (RFS) and cancer-specific survival (CSS) among patients subjected to radical nephroureterectomy (RNU) due to UTUC.
    Patients and methods: Analytical cohort was composed of a single-center series of 405 patients treated between January 1999 and December 2020. Thrombocytosis was defined as a platelet count exceeding the threshold value of 400 × 10
    Results: Preoperative thrombocytosis confirmed in 71 patients (17.5%) was significantly associated with the higher pathological tumor stage, lymph node metastasis, prior bladder cancer diagnosis, and preoperative anemia. With a median post-surgical follow-up period of 33.5 months, 125 patients (30.9%) experienced disease recurrence. The recurrence rate among patients with normal platelet levels was 13.6%, compared with 22.2% in those with preoperative thrombocytosis (p < 0.03). The 5-year RFS estimates reached 36.6% in the thrombocytosis-confirmed group. Multivariate analysis implied that preoperative thrombocytosis was a significant independent prognosticator of both poor RFS (HR 2.22, 95% CI 1.14-4.31, p = 0.02) and CSS (HR 2.48, 95% CI 1.14-3.09, p = 0.01).
    Conclusions: Patients with a clinically significant elevation of platelet count prior to RNU were more likely to have UTUC with advanced tumor stages and lymph node metastases. Preoperative thrombocytosis was an independent predictor of RFS and CSS in patients who underwent radical nephroureterectomy. Furthermore, preoperative thrombocytosis may complement and refine UTUC clinical prediction algorithms as an independent indicator of adverse survival outcomes.
