Complications and outcomes of post-transplant lymphocele management: a 30-year retrospective analysis.

Introduction: Current guidelines recommend percutaneous drainage as the first-line approach for the management of symptomatic lymphoceles following renal transplantation, with surgical fenestration reserved for refractory or recurrent cases. This study evaluates the effectiveness and safety of these therapeutic strategies in renal transplant recipients.

Methods: A retrospective analysis of 109 renal transplant recipients with symptomatic lymphoceles treated between 1993 and 2023 at a single public center was conducted.

Impact of B7-H3 expression on metastasis, immune exhaustion and JAK/STAT and PI3K/AKT pathways in clear cell renal cell carcinoma.

Immune checkpoint inhibitors in combination with tyrosine kinase inhibitors (TKIs) are improving the response rates of advanced renal cancer patients. However, many treated patients do not respond, making novel immune checkpoint-based immunotherapies potentially clinically beneficial only for specific groups of patients. We detected high expression of the immune checkpoint protein B7-H3 in clear cell renal cell carcinomas (ccRCCs) and evaluated B7-H3 immunohistochemistry staining in tissue microarray samples from two distinct renal cancer cohorts.

A functional role for glycosylated B7-H5/VISTA immune checkpoint protein in metastatic clear cell renal cell carcinoma.

Increased expression of the B7 family of immune checkpoint proteins hinders tumor elimination by the immune system. Expression levels of the B7-H5 protein were found to be upregulated in clear cell renal cell carcinomas (ccRCC). We here report the molecular, functional, and clinical characterization of B7-H5 from renal cancer cells and metastatic ccRCC tumors.

Predicting Survival of Metastatic Clear Cell Renal Cell Cancer Treated with VEGFR-TKI-Based Sequential Therapy.

(1) Objective: To develop a clinically useful nomogram that may provide a more individualized and accurate estimation of cancer-specific survival (CSS) for patients with clear-cell (CC) metastatic renal cell carcinoma (mRCC) treated with nephrectomy and vascular endothelial growth factor receptor-tyrosine kinase inhibitor (VEGFR-TKI)-based sequential therapy. (2) Methods: A prospectively maintained database of 145 patients with mRCC treated between 2008 and 2018 was analyzed to predict the CSS of patients receiving sunitinib and second- and third-line therapies according to current standards of practice. A nomogram based on four independent clinical predictors (Eastern Cooperative Oncology Group status, International Metastatic RCC Database Consortium score, the Morphology, Attenuation, Size and Structure criteria and Response Evaluation Criteria in Solid Tumors response criteria) was calculated.

Identification of miRNAs and Their Target Genes Associated with Sunitinib Resistance in Clear Cell Renal Cell Carcinoma Patients.

Sunitinib has greatly improved the survival of clear cell renal cell carcinoma (ccRCC) patients in recent years. However, 20-30% of treated patients do not respond. To identify miRNAs and genes associated with a response, comparisons were made between biopsies from responder and non-responder ccRCC patients.
