Abstract

Objective: To investigate the involvement of pretreatment C‐reactive protein (CRP) and neutrophil‐to‐lymphocyte ratio (NLR) in the prognosis of patients who underwent intravesical bacillus Calmette‐Guérin (BCG) therapy for non‐muscle invasive bladder cancer (NMIBC). Methods: The clinicopathological data of 1709 patients with NMIBC who underwent initial intravesical BCG therapy after transurethral resection of bladder tumor were retrospectively analyzed to evaluate the outcome of intravesical BCG therapy in a multicenter study conducted by the Japan Urological Oncology Group. The prognoses of these patients were analyzed to determine whether the biomarkers (CRP and NLR) could predict the efficacy of intravesical BCG therapy. Patients were divided into two groups according to the pretreatment CRP and NLR, with cutoff values defined as CRP ≥ 0.5 mg/dl and NLR ≥ 2.5, based on several previous reports. Results: In the univariable analysis, CRP ≥ 0.5 mg/dl was significantly associated with intravesical recurrence, cancer‐specific survival, and bladder cancer (BC) progression, while NLR ≥ 2.5 was not significantly associated with patient prognosis. In the multivariable analysis, CRP ≥ 0.5 mg/dl was significantly associated with intravesical recurrence and BC progression. The concordance index was used to examine the accuracy in predicting recurrence and progression events. While CRP was slightly, though not statistically significant, inferior to the European Association of Urology risk classification, the combination of them showed improved predictive accuracy. Conclusion: This study suggests that CRP can be a prognostic factor after intravesical BCG therapy and may provide useful data for determining treatment and follow‐up strategies for patients with NMIBC.

Abstract

Objective: To analyse the impact of histological discordance of subtypes (subtypes or divergent differentiation [DD]) in specimens from transurethral resection (TUR) and radical cystectomy (RC) on the outcome of the patients with bladder cancer receiving RC., Patients and Methods: We analysed data for 2570 patients from a Japanese nationwide cohort with bladder cancer treated with RC between January 2013 and December 2019 at 36 institutions. The non-urinary tract recurrence-free survival (NUTR-FS) and overall survival (OS) stratified by TUR or RC specimen histology were determined. We also elucidated the predictive factors for OS in patients with subtype/DD bladder cancer., Results: At median follow-up of 36.9 months, 835 (32.4%) patients had NUTR, and 691 (26.9%) died. No statistically significant disparities in OS or NUTR-FS were observed when TUR specimens were classified as pure-urothelial carcinoma (UC), subtypes, DD, or non-UC. Among 2449 patients diagnosed with pure-UC or subtype/DD in their TUR specimens, there was discordance between the pathological diagnosis in TUR and RC specimens. Histological subtypes in RC specimens had a significant prognostic impact. When we focused on 345 patients with subtype/DD in TUR specimens, a multivariate Cox regression analysis identified pre-RC neutrophil-lymphocyte ratio and pathological stage as independent prognostic factors for OS (P = 0.016 and P = 0.001, respectively). The presence of sarcomatoid subtype in TUR specimens and lymphovascular invasion in RC specimens had a marginal effect (P = 0.069 and P = 0.056, respectively)., Conclusion: This study demonstrated that the presence of subtype/DD in RC specimens but not in TUR specimens indicated a poor prognosis. In patients with subtype/DD in TUR specimens, pre-RC neutrophil-lymphocyte ratio and pathological stage were independent prognostic factors for OS., (© 2024 BJU International.)
