Cancer-associated fibroblasts (CAFs) exert multiple tumor-promoting functions and are key contributors to drug resistance. The mechanisms by which specific subsets of CAFs facilitate oxaliplatin resistance in colorectal cancer (CRC) have not been fully explored. This study found that THBS2 is positively associated with CAF activation, epithelial-mesenchymal transition (EMT), and chemoresistance at the pan-cancer level.

Department of Urology, Jules Bordet Institute and Erasme Hospital, Hôpital Universitaire de Bruxelles, Brussels, Belgium. Electronic address:

Categorization of patients according to their characteristics may simplify decision-making, but it fails to account for the continuous nature of risk and individual variability. Artificial intelligence has the ability to handle more complex continuous data for more precise, individualized recommendations, but several challenges must be overcome to unlock this potential.

In recent years, cancer immunotherapy has received widespread attention due to significant tumor clearance in some malignancies. Various immunotherapy approaches, including vaccines, immune checkpoint inhibitors, oncolytic virotherapy, bispecific T cell engagers, and adoptive T cell transfer, have completed or are undergoing clinical trials for prostate cancer. Despite immune checkpoint blockade's extraordinary effectiveness in treating a variety of cancers, targeted prostate cancer treatment using the immune system is still in its infancy.

Department of Urology, Unidade Local de Saúde de Santo António, Centro Hospitalar Universitário Do Porto, 8th floor, Largo Do Prof. Abel Salazar, 4099-001, Porto, Portugal.

Introduction: The primary aim of stone treatment is to achieve stone-free status. Residual fragments can cause stone growth, recurrence, urinary tract infections, and ureteric obstruction. Our goal was to describe the natural history of stone burden after retrograde intrarenal surgery (RIRS) based on stone-free status (SFS), evaluating stone growth and stone-events.

Background: Despite constant improvements, incontinence is one of the most relevant and quality-of-life-reducing side effects of radical prostatectomy (RP) and, in addition to patient-specific factors such as age, the experience of the surgeon/center and the surgical technique used play an important role.

Aims: To present current real-world data on short-term incontinence after RP from one of the largest German rehabilitation centers in 2022 and to compare it to the results from the same institution in 2016.

Methods And Results: Retrospective, unicentric, univariate analysis of data from 1394 men after RP in 2022 on admission and discharge from the rehabilitation clinic.

The recent advancements in cancer immunotherapy have spotlighted the potential of natural killer (NK) cells, particularly chimeric antigen receptor (CAR)-transduced NK cells. These cells, pivotal in innate immunity, offer a rapid and potent response against cancer cells and pathogens without the need for prior sensitization or recognition of peptide antigens. Although NK cell genetic modification is evolving, the viral transduction method continues to be inefficient and fraught with risks, often resulting in cytotoxic outcomes and the possibility of insertional mutagenesis.

Objective: This study aims to identify the risk factors for systemic inflammatory response syndrome (SIRS) after minimally invasive percutaneous nephrolithotomy (PCNL) with a controlled irrigation pressure and to find which patients undergoing PCNL are likely to develop SIRS under the pressure-controlled condition.

Methods: A total of 303 consecutive patients who underwent first-stage PCNL in our institute between July 2016 and June 2018 were retrospectively reviewed. All the procedures were performed with an 18 F tract using an irrigation pump setting the irrigation fluid pressure at 110 mmHg and the flow rate of irrigation at 0.

Background: Lung cancer is a leading cause of cancer-related mortality worldwide, with non-small cell lung cancer (NSCLC) comprising 85% of cases. Due to the lack of early clinical signs, metastasis often occurs before diagnosis, impacting treatment and prognosis. Cardiovascular disease (CVD) is a common comorbidity in lung cancer patients, with shared risk factors exacerbating outcomes.

Renorrhaphy is often performed after tumor resection during robotic-assisted laparoscopic partial nephrectomy (RAPN). This study aimed to investigate the association between renorrhaphy performance and inflammatory markers. A retrospective cohort study was conducted including patients with renal cell carcinoma who underwent RAPN at eight institutions in Japan between April 2016 and November 2023.

This study aimed to identify the predictive factors associated with the oncological outcomes of metastatic hormone-sensitive prostate cancer-related genes. A nomogram for predicting prostate cancer-specific survival (CSS) was constructed based on biopsy samples obtained from 103 patients with metastatic hormone-sensitive prostate cancer. We analyzed the association between clinical data and mRNA expression levels.

Background And Objective: Bladder cancer (BCa) imposes a substantial economic burden on health care systems and patients. Understanding these financial implications is crucial for effective resource allocation and optimization of treatment cost effectiveness. Here, we aim to systematically review and analyze the financial burden of BCa from the health care and patient perspectives.

Objectives: To determine how many cores should be collected per region of interest in magnetic resonance imaging (MRI)-guided fusion prostate biopsy. MRI-guided targeted prostate biopsy has led to improved detection of clinically significant prostate cancer (csPC); however, data is limited regarding the optimal number of biopsy cores that should be taken. An ideal number of cores maximizes clinically significant cancer detection while minimizing cost, discomfort, and procedure time.
