Objectives

Narrative objectives1

Some risk classifications to estimate the prognosis of non muscle bladder cancer (NMIBC) patients have disadvantages in clinical use. To investigate whether the EORTC(European Organazation for Research and Treatment of Cancer) risk stratification is useful to predict recurrence and progression in Japanese patients with NMIBC. In addition, we developed and validated the novel, and simple risk classification of recurrence.

Key inclusion criteria

In this multicentre retrospective cohort study, we analyzed data from patients with NMIBC who underwent initial TUR-Bt at 4 Juntendo University Hospitals and Teikyo University Hospital between 2000 and 2013 (JT cohort). To achieve adequate pathological staging, the complete resection aimed to include the muscle layer of the bladder wall.

Key exclusion criteria

Patients with any of the following were excluded from this analysis: (i) non-Urothelial carcinoma histology, (ii) follow-up periods < 3 months: (iii) history of muscle-invasive or metastatic bladder cancer; (iv) history of carcinoma of the urethra, prostate (ducts or stroma), or upper urinary tract; (v) history of local radiation therapy to the pelvis; (vi) history of every kind of chemotherapy; (vii) history of previous bacillus Calmette-Guerin (BCG) therapy.

Other related information

There are no significant differences in RFS rates and PFS rated between groups according to EORTC risk classification. We constructed a novel risk model predicting recurrence that classified patients into 3 groups using 4 independent prognostic factors to predict tumor recurrence based on Cox proportional hazards regression analysis. There was a significant difference in 3 year RFS rate among 3 groups.
