| Abstract |
To evaluate the impact of preoperative chronic kidney disease (CKD) on oncological outcomes after radical cystectomy (RC) for bladder cancer. We reviewed the medical records of patients with urothelial bladder carcinoma who underwent RC with curative intent at seven hospitals between 1990 and 2013. After excluding patients with a history of upper urinary tract urothelial cancer or neoadjuvant chemotherapy, we analyzed 594 cases for the study. Preoperative estimated glomerular filtration rate (eGFR) was calculated using the three-variable Japanese equation for GFR estimation from serum creatinine level and age. Patients were divided into four groups of different CKD stages based on eGFR values (mL/min/1.73 m2), i.e., ≥ 60 (CKD stages G1-2), 45-60 (G3a), 30-45 (G3b), and < 30 (G4-5). Survival was estimated using the Kaplan-Meier method. Univariate and multivariate Cox proportional hazards regression analyses addressed survivals after RC. Median age of patients was 67 years. Patients were classified into CKD stages: G1-2 (n = 388; 65.3%), G3a (n = 122; 20.5%), G3b (n = 51; 8.6%), and G4-5 (n = 33; 5.6%). During a median follow-up of 4.0 years, 200 and 164 patients showed cancer progression and died of bladder cancer, with the 5-year progression-free survival (PFS) and cancer-specific survival (CSS) of 64.9 and 70.2%, respectively. On multivariate analyses, CKD stages of G3b or greater, advanced pT stage, lymph node metastasis, and positive lymphovascular invasion were independent poor prognostic factors for PFS and CSS. We demonstrated that the advanced preoperative CKD stage was significantly associated with poor oncological outcomes of the bladder cancer after RC. |

Attention Score in Context
This research output has an Altmetric Attention Score of 15. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 28 February 2018.
All research outputs
#2,128,105
of 23,015,156 outputs
Outputs from World Journal of Urology
#127
of 2,116 outputs
Outputs of similar age
#50,309
of 438,556 outputs
Outputs of similar age from World Journal of Urology
#6
of 41 outputs
Altmetric has tracked 23,015,156 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 90th percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 2,116 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.1. This one has done particularly well, scoring higher than 94% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 438,556 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 88% of its contemporaries.
We're also able to compare this research output to 41 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 85% of its contemporaries.
