Blue vs white light for transurethral resection of non-muscle-invasive bladder cancer: an abridged Cochrane Review.

Objectives: To assess the effects of blue-light (BL)-enhanced transurethral resection of bladder tumour (TURBT) compared to white-light (WL)-based TURBT in the treatment of non-muscle-invasive bladder cancer (NMIBC).

Methods: Based on a published protocol, we performed a systematic search of multiple databases from their inception to March 2021. We included randomized controlled trials (RCTs) comparing blue-light (BL) TURBT to white-light (WL) TURBT.

Long-term follow-up of bladder cancer patients with disseminated tumour cells in bone marrow.

Background: The clinical relevance of polymerase chain reaction (PCR)-based techniques for detection of disseminated tumour cells (DTCs) in the bone marrow of bladder cancer (BCa) patients is still under debate, as data on long-term follow-up analysis have not yet been published.

Objective: The aim of the present prospective study was to assess the prognostic significance of DTCs detected by cytokeratin-20 (CK20) reverse-transcriptase PCR in bone marrow from BCa patients undergoing radical cystectomy (RC).

Design, Setting, And Participants: Bone marrow samples from 51 BCa patients with high-risk non-muscle-invasive or muscle-invasive urothelial carcinoma were drawn from the anterior iliac crest prior to RC.
