Purpose: Surgery remains the cornerstone of localized renal cell carcinoma (RCC) care. Pembrolizumab has recently been recommended as a standard of care for RCC patients who are at high risk of recurrence. Data regarding the efficacy of ICIs either alone or in combination with ICIs or VEGF TKIs for VTT shrinkage are scarce.

Purpose: Immune Checkpoints Inhibitors (ICI) have changed the therapeutic landscape of metastatic renal cell carcinoma first-line treatment with complete response (CR) at metastatic sites observed in 10 to 15% of cases. Delayed nephrectomy could be discussed for patients having a clinical benefit from immunotherapy-based treatment. However, it is unclear whether prior immunotherapy exposure adversely influences the complexity of surgery.

Background: There is a lack of published data on real-world cabozantinib use in patients with advanced renal cell carcinoma after prior vascular endothelial growth factor (VEGF)-targeted therapy.

Methods: CASSIOPE was a real-world, prospective, multicenter, non-interventional postauthorization safety study of cabozantinib in adult patients with advanced renal cell carcinoma in Europe following prior VEGF-targeted treatment (NCT03419572). Endpoints included cabozantinib utilization (dose modifications due to adverse events [AEs; primary endpoint], dose, dose modifications, and treatment duration), safety, effectiveness (progression-free survival [PFS], overall survival [OS], best overall response [BOR]), and healthcare resource utilization.

Several approaches have been utilised to deliver therapeutic nanoparticles inside the brain but rendered by certain limitation such as active efflux, non-stability, toxicity of the nanocarrier, transport, physicochemical properties and many more. In this context use of biocompatible nano carriers is currently investigated. We herein present the hypothesis that the nucleoside-lipid based conjugates (nucleolipids) which are biocompatible in nature and have molecular recognition can be tuned for improved permeation across blood-brain barrier (BBB).

Article Synopsis
  • Gender differences significantly impact bladder cancer prevalence, with men at higher risk but women often diagnosed later with more advanced disease.
  • Women face more challenges with treatment outcomes and experience higher rates of recurrence after certain therapies due to differing immunogenic responses.
  • There is a pressing need for more research on sex and gender effects in bladder cancer to bridge gaps in treatment and improve prognoses for women.

The ever-increasing use of immune checkpoint inhibitors (ICIs) has significantly improved cancer management, but at the cost of frequent immunologic side effects. Among them, neurologic immune-related adverse events (nirAEs) are less common but pose a challenge to clinicians due to their severity, heterogeneous nature and nonspecific clinical presentation, making diagnosis complex. The prognosis of these nirAEs, especially those related to the central nervous system (CNS), correlates with their rapid recognition and therapeutic management.

Article Synopsis
  • Metastatic kidney cancer patients who respond well to immunotherapy are being reconsidered for primary surgery, particularly nephron-sparing surgery, due to their prolonged survival.
  • A study analyzed 13 patients who had partial nephrectomy after achieving complete responses to immunotherapy, finding no positive surgical margins and acceptable complication rates.
  • Results showed promising renal function and oncological outcomes, indicating that partial nephrectomy is feasible after immunotherapy, but more research is necessary for definitive conclusions.

Three-dimensional (3D) cancer models, such as multicellular tumor spheroids (MCTS), are biological supports used for research in oncology, drug development and nanotoxicity assays. However, due to various analytical and biological challenges, the main recurring problem faced when developing this type of 3D model is the lack of reproducibility. When using a 3D support to assess the effect of biologics, small molecules or nanoparticles, it is essential that the support remains constant over time and multiples productions.

Ribonucleases (RNases) are ubiquitous enzymes that process or degrade RNA, essential for cellular functions and immune responses. The EndoU-like superfamily includes endoribonucleases conserved across bacteria, eukaryotes, and certain viruses, with an ancient evolutionary link to the ribonuclease A-like superfamily. Both bacterial EndoU and animal RNase A share a similar fold and function independently of cofactors.

Background And Objective: Metastatic prostate cancer (mPCa) harbors genomic alterations that may predict targeted therapy efficacy. These alterations can be identified not only in tissue but also directly in biologic fluids (ie, liquid biopsies), mainly blood. Liquid biopsies may represent a safer and less invasive alternative for monitoring patients treated for mPCa.
