Materials and Methods: In this retrospective cohort study, 551 patients with NMIBC treated between January 2007 and December 2024 were analyzed. Complete blood count parameters obtained within 30 days prior to transurethral resection were collected. The primary endpoints were disease recurrence and progression. Statistical analyses included the Mann\u2013Whitney U test, Kaplan\u2013Meier survival analysis, Cox proportional hazards regression, and receiver operating characteristic (ROC) curve analysis. Results: Complete data were available for 548 patients (mean age 66.3 \u00b1 11.3 years, 70.3% male). Disease recurrence occurred in 203 patients (37.0%) and progression in 60 patients (10.9%). Compared with the non-recurrence group, patients with recurrence had lower hemoglobin (11.8 \u00b1 2.3 vs. 13.2 \u00b1 2.4 g\/dL, p &lt; 0.001), higher lymphocyte counts (2.4 \u00b1 3.3 vs. 2.1 \u00b1 2.9 \u00d7103\/\u00b5L, p = 0.025), and lower neutrophil counts (5.3 \u00b1 3.0 vs. 6.1 \u00b1 3.4 \u00d7 103\/\u00b5L, p &lt; 0.001). In multivariable analysis, hemoglobin (HR 0.75, 95% CI 0.68\u20130.83, p &lt; 0.001), age (HR 1.02, 95% CI 1.00\u20131.03, p = 0.023), and carcinoma in situ (HR 1.69, 95% CI 1.13\u20132.53, p = 0.011) were independent predictors of recurrence. Hemoglobin yielded the highest AUC for predicting recurrence (0.692). Conclusions: Routinely available hematologic indices\u2014particularly hemoglobin concentration\u2014exhibit independent prognostic value in patients with NMIBC. Incorporating these parameters into established risk stratification models may enhance personalized treatment strategies.<\/jats:p>","DOI":"10.3390\/medicina62010051","type":"journal-article","created":{"date-parts":[[2025,12,29]],"date-time":"2025-12-29T06:25:51Z","timestamp":1766989551000},"page":"51","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Prognostic Significance of Hemogram Parameters in Non-Muscle Invasive Bladder Cancer: A Comprehensive Retrospective Analysis"],"prefix":"10.3390","volume":"62","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6325-1534","authenticated-orcid":false,"given":"Ali","family":"Nebio\u011flu","sequence":"first","affiliation":[{"name":"Urology Clinic, Mersin City Training and Research Hospital, Mersin 33240, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-4933-0808","authenticated-orcid":false,"given":"Ahmet","family":"Turhan","sequence":"additional","affiliation":[{"name":"Department of Urology, Faculty of Medicine, Mersin University, Mersin 33343, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9873-4920","authenticated-orcid":false,"given":"Mert","family":"Ba\u015farano\u011flu","sequence":"additional","affiliation":[{"name":"Department of Urology, Faculty of Medicine, Mersin University, Mersin 33343, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8624-0149","authenticated-orcid":false,"given":"Murat","family":"Bozlu","sequence":"additional","affiliation":[{"name":"Department of Urology, Faculty of Medicine, Mersin University, Mersin 33343, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7669-414X","authenticated-orcid":false,"given":"Erdem","family":"Akbay","sequence":"additional","affiliation":[{"name":"Department of Urology, Faculty of Medicine, Mersin University, Mersin 33343, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"95","DOI":"10.1111\/bju.16883","article-title":"Long-term oncological outcomes of bladder cancer: A population-based study with a 25-year follow-up","volume":"137","author":"Dey","year":"2025","journal-title":"BJU Int."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"201","DOI":"10.1111\/bju.16905","article-title":"The value of maintenance therapy in intermediate-risk non-muscle-invasive bladder cancer","volume":"137","author":"Zaurito","year":"2025","journal-title":"BJU Int."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"2460","DOI":"10.1111\/ans.70281","article-title":"BCG Intolerance in Nonmuscle Invasive Bladder Cancer-A Systematic Review","volume":"95","author":"Oh","year":"2025","journal-title":"ANZ J.
