Concomitant carcinoma in situ may not be a prognostic factor for patients with bladder cancer following radical cystectomy: a PRISMA-compliant systematic review and meta-analysis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundNumerous recent studies have shown that concomitant carcinoma in situ (CIS) can be closely associated with the prognosis of patients with bladder cancer (BCa). However, the prognostic value of CIS in BCa is still not conclusive. Hence, we performed a systematic review and meta-analysis to explore the association between CIS and clinicopathological features and the prognostic value for BCa following radical cystectomy.
methodsWe performed this study in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Relevant studies were systematically collected from PubMed, EMBASE, and Web of Science, with an expiration date of August 2018. Hazard ratios and 95% confidence intervals (CIs) were pooled to assess the intensity of association. All data were analyzed by Stata 12.0. Moreover, heterogeneity and publication bias were determined, and sensitivity analysis was performed to examine whether the findings of the meta-analysis were robust.
resultsA total of 18,845 patients from 24 studies were included in the analysis. Our results indicated that CIS has no significant correlation with cancer-specific mortality (CSM) (pooled HR = 0.97, 95% CI 0.93-1.00, p = 0.059), overall mortality (OM) (pooled HR = 0.93, 95% CI 0.85-1.01, p = 0.076), overall survival (OS) (pooled HR = 1.04, 95% CI 0.96-1.12, p = 0.386), cancer-specific survival (CSS) (pooled HR = 1.06, 95% CI 0.97-1.16, p = 0.186), recurrence-free survival (RFS) (HR = 1.05, 95% CI 0.99-1.11, p = 0.098) or recurrence (pooled HR = 1.04, 95% CI 0.98-1.11, p = 0.212) in BCa patients. In addition, CIS was not correlated with gender (male vs. female, OR = 1.00, 95% CI 0.74-1.34, p = 0.978), pathological stage (III/IV vs. I/II: OR = 0.74, 95% CI 0.50-1.10, p = 0.132), tumor grade (1/2 vs. 3: OR = 3.38, 95% CI 0.73-15.65, p = 0.119), soft tissue surgical margin (STSM) (+ vs. - : OR = 1.20, 95% CI 0.97-1.48, p = 0.093) or lymphovascular invasion (LVI) (+ vs. - : OR = 0.92, 95% CI 0.62-1.38, p = 0.702),but was closely related to adjuvant chemotherapy (ACT) (yes vs. no, OR = 1.17, 95% CI 1.03-1.32, p = 0.019). Furthermore, these findings were demonstrated to be reliable by our sensitivity and subgroup analysis.
conclusionsThe prognostic value of CIS in BCa remains inconclusive in patients submitted to RC. Our data indicated that CIS may have no significant correlation with the prognosis and clinicopathological parameters of BCa patients, and also may not be applied to risk stratification or individualized therapy in BCa patients. Further research should be conducted to confirm our findings.
