Temporal dynamics of immune cell patterns in bladder cancer patients receiving Bacillus Calmette-Guérin therapy.

Background: Bacillus Calmette-Guérin (BCG) is capable of enhancing the infiltration of immune cells into the tumour. However the temporal dynamics of immune cell patterns in patients receiving BCG instillation remains unclear.

Methods: Ninety-six patients who underwent intravesical BCG therapy, comprising 46 responders and 50 non-responders, were retrospectively enroled to explore the evolving immune landscape.

Regular gastroscopy and colonoscopy during the evaluation of urachal cancer: do we really need them?

Purpose: Urachal cancer is similar to gastrointestinal adenocarcinoma in histology, and gastroscopy/colonoscopy is often administered during perioperative evaluation. However, gastroscopy and colonoscopy have corresponding disadvantages. This study discusses whether gastroscopy/colonoscopy is truly necessary for patients with urachal cancer.

Optimal interval timing between transurethral resection of bladder tumors and Bacillus Calmette-Guerin perfusion.

Objective: There is no consensus regarding the best interval time between transurethral resection of a bladder tumor and Bacillus Calmette-Guerin (BCG) perfusion. This study was to explore whether the interval time has an impact on the prognosis and adverse effects.

Methods: We retrospectively reviewed the clinical data of patients who received BCG intravesical perfusion at Sun Yat-sen University Cancer Center (SYSUCC) from September 2015 to October 2021.
