However, the prevalence of SRDs in patients with high-grade (HGBC) or muscle-invasive bladder carcinoma (MIBC) has not been systematically investigated. We aimed to evaluate SRD prevalence and to assess the potential role of chest high-resolution computed tomography (HRCT) in a population with histologically confirmed HGBC or MIBC. Methods: We retrospectively analyzed 166 patients with histologically confirmed HGBC\/MIBC who underwent staging HRCT. SRDs\u2014including emphysema, suspicious pulmonary nodules, airway disease, interstitial lung disease (ILD), and coronary artery calcifications (CAC)\u2014were assessed. Associations between smoking status and SRDs were evaluated using binary logistic regression, and odds ratios (OR) with 95% confidence intervals (CI) were calculated. Results: Overall, 60.2% of patients had at least one SRD. Smokers showed a significantly higher SRD prevalence than non-smokers (p &lt; 0.05). Pulmonary SRDs were observed in 31.9% of patients, with emphysema being most strongly associated with smoking (p &lt; 0.01). Suspicious pulmonary nodules (Lung-RADS \u2265 3) were detected in 6.6% of patients, more commonly among smokers (72.7%), though the difference was not statistically significant. Histological confirmation, available for 45% of these nodules, revealed primary lung cancers rather than metastatic bladder carcinoma in all verified cases. Conclusions: Patients with HGBC\/MIBC demonstrate a high prevalence of SRDs, supporting the integration of chest HRCT into staging protocols. HRCT may enable early detection of clinically relevant comorbidities and help identify candidates for lung cancer screening.<\/jats:p>","DOI":"10.3390\/cancers17233741","type":"journal-article","created":{"date-parts":[[2025,11,24]],"date-time":"2025-11-24T11:47:22Z","timestamp":1763984842000},"page":"3741","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["High Prevalence of Smoking-Related Diseases in High-Grade and Muscle-Invasive Bladder Cancer: Opportunities for Lung Cancer Screening"],"prefix":"10.3390","volume":"17","author":[{"given":"Riccardo","family":"Regazzo","sequence":"first","affiliation":[{"name":"Department of Radiology, IRCCS Azienda-Ospedaliero Universitaria di Bologna, 40138 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4827-6810","authenticated-orcid":false,"given":"Federica","family":"Ciccarese","sequence":"additional","affiliation":[{"name":"Department of Radiology, IRCCS Azienda-Ospedaliero Universitaria di Bologna, 40138 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Simone","family":"Paglialonga","sequence":"additional","affiliation":[{"name":"Department of Radiology, IRCCS Azienda-Ospedaliero Universitaria di Bologna, 40138 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elio","family":"Ren\u00f2","sequence":"additional","affiliation":[{"name":"Department of Radiology, IRCCS Azienda-Ospedaliero Universitaria di Bologna, 40138 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caterina","family":"Gaudiano","sequence":"additional","affiliation":[{"name":"Department of Radiology, IRCCS Azienda-Ospedaliero Universitaria di Bologna, 40138 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Beniamino","family":"Corcioni","sequence":"additional","affiliation":[{"name":"Department of Radiology, IRCCS Azienda-Ospedaliero Universitaria di Bologna, 40138 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francesco","family":"Chessa","sequence":"additional","affiliation":[{"name":"Department of Medical and Surgical Sciences (DIMEC), University of Bologna, 40136 Bologna, Italy"},{"name":"Division of Urology, IRCCS Azienda-Ospedaliero Universitaria di Bologna, 40138 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Riccardo","family":"Schiavina","sequence":"additional","affiliation":[{"name":"Department of Medical and Surgical Sciences (DIMEC), University of Bologna, 40136 Bologna, Italy"},{"name":"Division of Urology, IRCCS Azienda-Ospedaliero Universitaria di Bologna, 40138 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cristina","family":"Mosconi","sequence":"additional","affiliation":[{"name":"Department of Radiology, IRCCS Azienda-Ospedaliero Universitaria di Bologna, 40138 Bologna, Italy"},{"name":"Department of Medical and Surgical Sciences (DIMEC), University of Bologna, 40136 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,11,23]]},"reference":[{"key":"ref_1","first-page":"209","article-title":"Global Cancer Statistics 2020: GLOBOCAN Estimates of Incidence and Mortality Worldwide for 36 Cancers in 185 Countries","volume":"71","author":"Sung","year":"2021","journal-title":"CA Cancer J.
