Special Issue Information

Dear Colleagues,

This collection is the second edition of a previous Special Issue on “New Advances in Urothelial Cancer: Diagnosis, Therapy and Prognosis” (https://www.mdpi.com/journal/cancers/special_issues/UCs).

Urothelial cancers are the sixth most common tumors in developed countries. Bladder tumors account for 90–95% of UCs and are the most common urinary tract malignancy; by contrast, upper urinary tract UCs are uncommon and account for only 5–10% of UCs. In recent years, new urothelial biomarkers have been proposed in their diagnostic and prognostic role; liquid biopsy has arisen as an important tool for urothelial cancer early detection and prognosis, identifying different pathways of cell signaling, proliferation, and apoptosis changes in tumor biology and progression. New immunotherapy agents based on checkpoint inhibitor-optimized cancer therapy and oncologic outcomes have emerged, and device-assisted therapy (EMDA, thermochemotherapy) has been outlined as a preserving approach to recurrent non-muscle invasive bladder disease, while the minimally invasive approach of robotic surgery has been found to reduce adverse events and hospital stay when major urologic surgery is needed. The purpose of this Special Issue is to identify and summarize the latest innovations in urothelial cancer management, overcome present challenges and open new paths to future strategies.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Cancers is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Despite its immunogenic nature, bladder cancer (BCa) responds sub-optimally to FDA-approved immunotherapy. Background/Objectives: We have previously shown that natural killer (NK) cells are major contributors to overall patient survival in BCa. In our efforts to identify clinically approved agents that enhance NK cell activation, we identified eribulin, a microtubule destabilizer primarily used in breast cancer. Ongoing clinical trials are investigating the potential integration of eribulin into the standard of care in BCa; however, the mechanistic rationale for these trials remains unclear. Methods: Here, we explore the effects of low-dose eribulin on direct NK cell activation in vitro, including on primary patient samples, and in vivo utilizing multiple murine models. Flow cytometry and RNA sequencing were employed to identify the mechanism of NK cell activation by eribulin, which was associated with increased migration and cytotoxicity of NK cells against BCa cells. Results: We found that localized eribulin instillation significantly reduces bladder tumor burden and improves survival in primary BCa in an NK cell-dependent manner. Importantly, eribulin promoted the shift of patient-derived intratumoral NK cells towards an anti-tumor CD49a+ CD103+ NK subset (ieILC1-like) while diminishing the dysfunctional NR4A2-expressing CD49a NK subset. Moreover, it decreased the overall expression of exhaustion markers on NK cells, a pattern replicated in our murine models. Conclusions: These findings are paradigm-shifting given that chemotherapy is traditionally considered immunosuppressive. Our study reveals the novel effect of low-dose eribulin chemotherapy in inhibiting bladder tumor growth by enhancing anti-tumor NK cell immunity, challenging previous assumptions and opening new therapeutic approaches to improve antitumor immunity.
