The prognostic value of tumor architecture in patients with upper tract urothelial carcinoma treated with radical nephroureterectomy: A systematic review and meta-analysis.

Background And Purpose: There is a lack of consensus regarding the prognostic value of tumor architecture (sessile vs. papillary) in upper tract urothelial carcinoma (UTUC) treated with radical nephroureterectomy (RNU). The aim of the present study was to analyze the current evidence regarding the prognostic role of tumor architecture in patients undergoing RNU for UTUC through a systematic review and meta-analysis.

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.

Background: Numerous 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.

The impact of lymphovascular invasion in patients with prostate cancer following radical prostatectomy and its association with their clinicopathological features: An updated PRISMA-compliant systematic review and meta-analysis.

Objective: Numerous studies have shown that lymphovascular invasion (LVI) is linked to biochemical recurrence (BCR) in prostate cancer (PCa) patients following radical prostatectomy (RP). However, the actual clinicopathological impacts of LVI remain unclear. Thus, we performed a meta-analysis to evaluate the pathologic and prognostic impacts of LVI in PCa patients.

Comparison of selective and main renal artery clamping in partial nephrectomy of renal cell cancer: A PRISMA-compliant systematic review and meta-analysis.

Background: The aim of the present study was to perform a systematic review and meta-analysis of the studies comparing the efficiency and safety of selective renal artery clamping (SAC) and main renal artery clamping (MAC) in partial nephrectomy (PN) for renal cell cancer (RCC).

Methods: According to the Preferred Reporting Items for Systematic reviews and Meta-Analyses statement, a literature search on PubMed, EMBASE, Web of Science, and Chinese National Knowledge Infrastructure were conducted to identify relevant studies published through December 2017. Outcomes of interest included baseline characteristics and perioperative surgical variables.

Positive surgical margin is associated with biochemical recurrence risk following radical prostatectomy: a meta-analysis from high-quality retrospective cohort studies.

Background And Purpose: Although numerous studies have shown that positive surgical margin (PSM) is linked to biochemical recurrence (BCR) in prostate cancer (PCa), the research results have been inconsistent. This study aimed to explore the association between PSM and BCR in patients with PCa following radical prostatectomy (RP).

Materials And Methods: In accordance with the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), PubMed, EMBASE and Wan Fang databases were searched for eligible studies from inception to November 2017.

Surgical margin status and its impact on prostate cancer prognosis after radical prostatectomy: a meta-analysis.

Background And Purpose: Positive surgical margins (PSMs) correlate with adverse outcomes in numerous solid tumours. However, the prognostic value of PSMs in prostate cancer (PCa) patients who underwent radical prostatectomy remains unclear. Herein, we performed a meta-analysis to evaluate the association between PSMs and the prognostic value for biochemical recurrence-free survival (BRFS), cancer-specific survival (CSS), overall survival (OS), cancer-specific mortality (CSM) and overall mortality (OM) in PCa patients.
