Trimodal therapy vs. radical cystectomy for muscle-invasive bladder cancer: A Canadian cost-effectiveness analysis

Trimodal therapy vs radical cystectomy in patients with muscle-invasive bladder cancer: a systematic review and meta-analysis of comparative studies

OBJECTIVE

To perform a systematic review and meta-analysis of trials comparing trimodal therapy (TMT) and radical cystectomy (RC), evaluating differences in terms of oncological outcomes, quality of life, and costs.

MATERIALS AND METHODS

In July 2023, a literature search of multiple databases was conducted to identify studies analysing patients with cT2-4 N any M0 muscle-invasive bladder cancer (MIBC; Patients) receiving TMT (Intervention) compared to RC (Comparison), to evaluate survival outcomes, recurrence rates, costs, and quality of life (Outcomes). The primary outcome was overall survival (OS). Secondary outcomes were cancer-specific survival (CSS) and metastasis-free survival (MFS). Hazard ratios (HRs) were used to analyse survival outcomes according to different treatment modalities and odds ratios were used to evaluate the likelihood of receiving each type of treatment according to T stage.

RESULTS

No significant difference in terms of OS was observed between RC and TMT (HR 1.07, 95% confidence interval [CI] 0.81-1.4; P = 0.6), even when analysing radiation therapy regimens ≥60 Gy (HR 1.02, 95% CI 0.69-1.52; P = 0.9). No significant difference was observed in CSS (HR 1.12, 95% CI 0.79-1.57, P = 0.5) or MFS (HR 0.88, 95% CI 0.66-1.16; P = 0.3). The mean cost of TMT was significantly higher than that of RC ($289 142 vs $148 757; P < 0.001), with greater effectiveness in terms of cost per quality-adjusted life-year. TMT ensured significantly higher general quality-of-life scores.

CONCLUSION

Trimodal therapy appeared to yield comparable oncological outcomes to RC concerning OS, CSS and MFS, while providing superior patient quality of life and cost effectiveness.

Comparing trimodal therapy with radical cystectomy in muscle-invasive bladder cancer: an updated meta-analysis

Background

We conducted this meta-analysis to compare the two muscle-invasive bladder cancer (MIBC) treatment modalities in terms of cancer-specific survival (CSS) and other outcome indicators.

Method

A systematic review and meta-analysis were performed in accordance with the Preferred Reporting Items for Systematic Reviews (PRISMA) guidelines. The search was conducted using various academic databases including Scopus, PubMed, Cochrane database, EMBASE, Chinese biomedical literature database, Wan fang databases, and China National Knowledge Internet databases between 1966 and December 2023. This review protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO) No. (CRD42023398977).

Result

This study included a total of 54,816 patients diagnosed with bladder cancer from 14 studies, of which 6,228 patients were assigned to the trimodal therapy (TMT) group and 48,588 patients were assigned to the radical cystectomy (RC) group. Based on the results, the RC group exhibited a higher rate of survival than the TMT group [pooled hazard ratio (HR) = 1.23, 95% CI: 1.18-1.28, Z = 1.46, P < 0.001]. In terms of CSS, patients in the RC group had a longer CSS compared with those in the TMT group (pooled HR = 1.47, 95% CI: 1.29-1.67, Z = 5.893, P < 0.001). Compared with RC, TMT is significantly associated with an increased risk of both types of mortality (pooled HR: 1.30, P < 0.001).

Conclusion

Overall, the findings of this meta-analysis suggest that RC treatment may be associated with improved overall survival. Moreover, it was observed that cancer-specific survival was significantly prolonged among patients in the RC group as opposed to those who received TMT. In addition, it was shown that patients who received TMT exhibited a higher risk of all-cause mortality when compared with those who underwent RC.

A Retrospective Analysis of the Challenges of Urothelial Cancer Management during the COVID-19 Pandemic at a Single Academic Center in Romania

The COVID-19 pandemic caused major changes in the healthcare sector due to adaptations required to hospitalize and treat an impressive number of patients. This retrospective study intended to collect reliable information on urothelial cancer patients in Romania. The primary objective was to compare the pre-pandemic and pandemic periods to observe the differences that occurred in the management of patients with urothelial carcinoma. The secondary objective was to determine the risk factors for urothelial cancer progression in the study cohort correlated with the COVID-19 pandemic. All patients that were diagnosed and treated at our clinic with a diagnosis of urothelial carcinoma (transitional cell carcinoma) during 2019–2021 were included in the current study. A total of 1122 eligible unique cases were identified during the study period. The number of patients who underwent intervention in the pre-pandemic year was 421, followed by a 22.6% decrease in 2020 to 326 cases and a 13.1% increase in 2021 to 375 cases. The proportion of muscle-invasive bladder cancer (MIBC) cases was significantly higher during the pandemic years, from 30.5% MIBC cases in 2019 to 37.4% in 2020 and 39.4% in 2021, suggesting a delay in presentations during the pandemic. Stage III and IV (TNM) cases were significantly more frequent, even though approximately 40% of all patients were operated on in stage I. The number of cystectomies increased significantly, from 5.2% in 2019 and 4.3% in 2020 to 10.1% in 2021, while the number of elective surgeries decreased, although no significant difference was observed regarding the in-hospital mortality and disease progression at six months. Patients with stage III and IV at presentation had the highest likelihood of disease progression at six months (HR = 5.61). Distant invasion was the second highest risk factor (HR = 5.13), followed by MIBC type (HR = 2.49). Nevertheless, the duration of hospitalization and year of diagnosis during the COVID-19 pandemic were not significant risk factors for cancer progression at six months. It can be concluded that there was a significant delay in patient presentations in 2020, and we advocate for increased public health awareness for urothelial cancer and increased attention toward the screening and management of these patients in the following years.
