Special Issue Information

Dear Colleagues,

Advanced and metastatic urothelial carcinoma (UC) remains a significant clinical challenge, with historically poor survival outcomes despite recent therapeutic advancements. The management of these patients has evolved beyond traditional platinum-based chemotherapy to include immune checkpoint inhibitors, targeted therapies, and combination regimens, which have shown promising efficacy in selected populations. Personalized treatment strategies, guided by molecular profiling and predictive biomarkers, are increasingly shaping clinical decision-making. Moreover, understanding mechanisms of resistance and optimizing sequencing of therapies are critical for improving long-term outcomes. In addition to systemic treatment, multidisciplinary approaches integrating surgery and radiotherapy may offer benefits in selected cases.

This Special Issue will gather high-quality contributions that address the latest developments in therapeutic strategies for advanced or metastatic UC. We welcome original research, clinical trials, retrospective studies, and comprehensive reviews on topics including novel systemic therapies, immunotherapy combinations, biomarker-driven treatment approaches, and real-world management strategies. Studies assessing treatment outcomes, toxicity profiles, and cost-effectiveness are also highly encouraged.

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 short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Current Oncology is an international peer-reviewed open access monthly 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 2200 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.

Second-line chemotherapy is widely used in metastatic urothelial carcinoma after progression on first-line platinum-based therapy, but its independent contribution to survival, as opposed to selection of healthier patients, remains unclear. In this multicenter retrospective cohort of 142 patients treated with first-line platinum-based chemotherapy across seven Turkish centers, overall survival (OS) from first-line progression was compared between patients who received second-line chemotherapy (n = 80) and those who did not (n = 62), using multivariable Cox regression, inverse probability of treatment weighting (IPTW), propensity-score matching, landmark analysis, and a time-dependent Cox model. Median OS was 7.4 versus 4.7 months (log-rank p = 0.064). Second-line chemotherapy was independently associated with improved OS on multivariable analysis (adjusted hazard ratio [aHR] 0.620; 95% confidence interval [CI] 0.423–0.907; p = 0.014); Eastern Cooperative Oncology Group (ECOG) performance status ≥ 2 (aHR 3.881; p = 0.001) and lower albumin (aHR 0.671; p = 0.018) were also independent predictors. The association remained significant after IPTW (HR 0.648; p = 0.025) and after a time-dependent Cox model (HR 0.632; p = 0.019), and was unchanged in ECOG-restricted and Bellmunt-adjusted analyses (p = 0.008, p = 0.029); it narrowly missed significance after propensity-score matching (HR 0.645; p = 0.051) and did not reach significance in the 3-month landmark analysis (HR 0.743; p = 0.180). Power was limited (~49%). In a time-dependent Cox model—the analysis least susceptible to immortal-time bias, as it retains the full cohort and classifies pre-treatment person-time as unexposed—second-line chemotherapy remained independently associated with improved OS (HR 0.632; p = 0.019), closely consistent with the primary multivariable estimate. The conventional Cox, IPTW, and propensity-score-matched analyses, which treat second-line receipt as a baseline exposure, were directionally concordant but share a common time-related bias and are therefore not independent confirmations. ECOG performance status was a consistent predictor throughout. Full article
