| Abstract | Abstract Background: Biomarkers acquired from blood samples are easy to obtain and cost-effective, have attracted considerable interest and have been widely investigated. Inflammation plays a crucial role in cancer cell initiation, proliferation and metastasis. We aimed to evaluate the association of preoperative systemic immune-inflammation index (SII) with the clinical outcomes of patients diagnosed with bladder cancer and who underwent radical cystectomy (RC). Materials and Methods: Data from patients diagnosed with bladder cancer and who underwent RC from December 2010 to May 2020 in West China Hospital were retrospectively collected according to the inclusion and exclusion criteria. Patients were divided into a low SII group and a high SII group according to SII level. Survival outcomes were obtained during follow-up. The primary endpoints were overall survival (OS) and recurrence-free survival (RFS). Cox proportional hazards models were performed to estimate the effect of SII on OS and RFS and control for potential confoundings. Subgroup analyses were conducted and the log likelihood ratio test was used to inspect the interaction. Results: A total of 725 patients who underwent RC were ultimately involved in this study. Of these patients, 621 (85.66%) were male and 104 (14.34%) were female. The median age was 65 years. The median follow-up was 36 months for OS and 33.6 months for RFS. The optimal cut-off value was identified as 554.23×109/L. A total of 467 (64.41%) patients were divided into the low SII group (SII<554×109/L) and 258 (35.59%) patients were divided into the high SII group (SII≥554×109/L) accordingly. Multivariable Cox proportional hazard regression demonstrated that a high SII was an independent prognostic factor for worse OS (HR: 1.69 95% CI: 1.02-2.81, P=0.0436) and RFS (HR: 1.88, 95% CI: 1.09-3.24, P=0.0229) in NMIBC patients. A high SII was found to be an independent prognostic factor for worse RFS in patients with HBP (HR: 2.11, 95% CI: 1.34-3.30, P=0.0012), DM (HR: 3.76, 95% CI: 1.73-8.15, P=0.0008) and without PNI (HR: 1.32, 95% CI: 1.04-1.69, P=0.0238). Conclusions: SII was a potential prognostic predictor for bladder cancer patients who underwent RC. Further prospective multi-center investigations are warranted. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
