To parallelly compare the efficacy of neoadjuvant immunotherapy (tislelizumab), chemotherapy (gemcitabine and cisplatin), combination therapy (tislelizumab + GC) in patients with muscle-invasive bladder cancer (MIBC) explore predictors, we perform a multi-center, real-world cohort study that enrolls 253 treated treatments (combination therapy: 98, chemotherapy: 107, immunotherapy: 48) from 15 tertiary hospitals. We demonstrate achieves highest complete response rate pathological downstaging compared or chemotherapy. develop validate an prediction model consisting pretreatment clinical characteristics, which can pinpoint candidates to receive therapy. also preliminarily reveal who achieve after plus maximal transurethral resection tumor may be safe preservation Overall, this highlights benefit based on tislelizumab for MIBC.

Bladder cancer (BCa) is one of the most common and expensive urinary system malignancies for its high recurrence progression rate. In recent years, immense amounts studies have been carried out to bring a more comprehensive cognition numerous promising clinic approaches BCa therapy. The development innovative enhanced cystoscopy techniques (optical techniques, imaging systems) tumor biomarkers-based non-invasive urine screening (DNA methylation-based test) would dramatically improve accuracy detection, reducing risk BCa. Moreover, intravesical instillation systemic therapeutic strategies (cocktail therapy, immunotherapy, vaccine targeted therapy) also provide plentiful measures break predicament Several exploratory clinical studies, including novel surgical approaches, pharmaceutical compositions, bladder preservation emerged continually, which are supposed be candidates treatment. Here, advances prospects diagnosis, or treatment, drug delivery systems therapy reviewed in this paper.

Immunotherapy is one of the fastest developing areas in field oncology. Many immunological treatment strategies for refractory tumors have been approved and marketed. Nevertheless, much clinical preclinical experimental evidence has shown that efficacy immunotherapy tumor varies markedly among individuals. The commensal microbiome mainly colonizes intestinal lumen humans, affected by a variety factors exhibits individual variation. Moreover, gut considered largest immune organ body due to its influence on system. In last few decades, with development next-generation sequencing (NGS) techniques in-depth research, view microbiota intervenes antitumor through system gradually confirmed. Here, we review important studies published recent years focusing influences progression malignancy. Furthermore, discuss mechanism which affect immunotherapy, including checkpoint blockade (ICB) adoptive T-cell therapy (ACT), modulating microbial composition facilitate response. Finally, opportunity some challenges are mentioned enable more systematic understanding future promote basic research application related fields.

Abstract Mechanomedicine is an emerging field focused on characterizing mechanical changes in cells and tissues coupled with a specific disease. Understanding the cues that drive disease progression, whether tissue stiffening can precede development, crucial order to define new biomarkers improve develop diagnostic prognostic tools. Classically known stromal regulators, such as fibroblasts, more recently acknowledged factors microbiome extracellular vesicles, play role modifications stroma matrix (ECM). These ultimately lead alteration of properties (stiffness) tissue, contributing onset progression. We describe here classic mediators ECM remodeling, discuss state-of-the-art studies fingerprints urological diseases, showing general trend between increased stiffness severity Finally, we point clinical potential factor field, well possible target for innovative drugs.

Gut microbiota represents a hidden treasure vault encompassing trillions of microorganisms that inhabit the intestinal epithelial barrier host. In past decade, numerous in-vitro , animal and clinical studies have revealed profound roles gut in maintaining homeostasis various physiological functions, especially immune modulation, remarkable differences configuration microbial communities between cancers healthy individuals. addition, although considerable efforts been devoted to cancer treatments, there remain many patients succumb their disease with incremental burden worldwide. Nevertheless, compared stability human genome, plasticity renders it promising opportunity for individualized treatment. Meanwhile, burgeoning findings indicate is involved close interactions outcomes diverse immunotherapy protocols, including checkpoint blockade therapy, allogeneic hematopoietic stem cell transplantation, chimeric antigen receptor T therapy. Here, we reviewed evidence capacity microflora modulate immunotherapies, highlighted opportunities microbiota-based prognostic prediction, as well microbiotherapy by targeting potentiate anticancer efficacy while attenuating toxicity, which will be pivotal development personalized treatment strategies.
