Introduction: In patients with non-metastatic muscle-invasive bladder cancer (MIBC) fit for curative therapy, a multidisciplinary approach consisting is recommended. This approach includes local treatment (usually radical cystectomy), ideally combined with neoadjuvant chemotherapy (NACT). Despite a survival benefit with NACT, uptake remains low. We assessed NACT consultation in Alberta and examined associative factors, as well as the relationship to survival.Methods: Patients with MIBC were identified through the Alberta Cancer Registry. Demographic and clinicopathologic information was collected from electronic medical records between 2007 and 2011. In addition to descriptive statistics, logistic regression was used to determine factors associated with receiving NACT consultation. Overall survival was described using a Kaplan-Meier estimate.Results: Of the 315 radical cystectomy patients, 140 (45.1%, 95% confidence interval [CI] 39.5, 50.8) received NACT consultation. Patients ≥80 years (odds ratio [OR] 0.21, 95% CI 0.08, 0.57, p = 0.002) and those treated in Calgary (OR 0.11, 95% CI 0.05, 0.25, p < 0.001) were less likely to receive NACT consultation. The rate of NACT consultation increased steadily from 2007 to 2011 (OR 1.23, 95% CI 1.04, 1.45 per year of diagnosis, p = 0.018). After a median follow-up of 28.1 months (range: 14.6–50.3), median survival was 54.7 months for patients who received NACT consultation versus 31.2 months for those who did not (p = 0.030).Conclusions: NACT consultation in patients with MIBC undergoing radical cystectomy has improved over time; however, regional differences underscore the need for a standardized approach to NACT consultation, including common referral mechanisms.

Abstract Background Most patients with muscle-invasive bladder cancer (MIBC) developed metastasis within 2 years, even after radical cystectomy (RC). The recurrence rate of MIBC was more than 50% of the cases. A meta-analysis conducted by Yin et al. showed that neoadjuvant chemotherapy (NAC) + RC improves overall survival in MIBC compared with RC only. However, a new meta-analysis by Li et al. concluded that NAC + RC was not superior to RC only in improving overall survival. The inconsistencies of these studies required further comprehensive analysis to recommend NAC use in bladder cancer treatment. Therefore, this meta-analysis aims to analyze previous studies that compare the efficacy of NAC + RC versus RC only to improve overall survival of MIBC. Methods The articles were searched using Pubmed with keywords “muscle-invasive bladder cancer”, “neoadjuvant chemotherapy”, “cystectomy”, and “overall survival”. The articles that were published until June 2020 were screened. The overall survival outcome was analyzed as hazard ratio (HR) and presented in a forest plot. Result Seventeen studies were included in meta-analysis with a total sample of 13,391 patients, consist of 2890 received NAC followed by RC and 10,418 underwent RC only. Two studies used methotrexate/vinblastine/doxorubicin/cisplatin (MVAC), two studies used gemcitabine/cisplatin (GC), one study used Cisplatin-based regimen, one study used MVAC or GC, one study used gemcitabine/carboplatin (GCarbo) or GC or MVAC, one study used Cisplatin/Gemcitabine or MVAC, one study used Cisplatin only, one study used Cisplatin-based (GC, MVAC) or non-Cisplatin-based (combined paclitaxel/gemcitabine/carboplatin), one study used GC, MVAC, Carboplatin, or Gemcitabine/Nedaplatin (GN), and five studies did not mention the regimen The overall survival in the NAC + RC only group was significantly better than the RC only group (HR 0.82 [0.71–0.95], p = 0.009). Conclusion NAC + RC is recommended to improve overall survival in MIBC patients. A further study assessing side effects and quality of life regarding NAC + RC is needed to establish a strong recommendation regarding this therapy.

The Relationship

Abstract Purpose To examine the relationship between the number of tumour draining sentinel nodes (SNs) and pathoanatomical outcomes, in muscle-invasive bladder cancer (MIBC), in patients undergoing neoadjuvant chemotherapy (NAC) and radical cystectomy (RC). Materials and Methods In an ongoing prospective multicenter study, we included 230 patients with suspected urothelial MIBC from ten Swedish urological centers. All underwent TURb and clinical staging. From the cohort, 116 patients with urothelial MIBC; cT2-cT4aN0M0, underwent radical cystectomy (RC) and lymphadenectomy with SN-detection (SNd). 83 patients received cisplatin-based NAC and 33 were NAC-naïve. The number and locations of detected SNs and non-SNs were recorded for each patient. The NAC treated patients were categorized by pathoanatomical outcomes post-RC into three groups: complete responders (CR), stable disease (SD) and progressive disease (PD). Selected covariates with possible impact on SN-yield were tested in uni -and multivariate analyses for NAC-treated patients only. Results In NAC treated patients, the mean number of SNs was significantly higher in CR patients (3.3) and SD patients (3.6) compared with PD patients (1.4) (p = 0.034). In a linear multivariate regression model, the number of harvested nodes was the only independent variable that affected the number of SNs (p = 0.0004). Conclusions The number of tumor-draining SNs in NAC-treated patients was significantly lower in patients with progressive disease.

503 Background: Neoadjuvant chemotherapy (NAC) improves overall survival (OS) for patients with muscle invasive bladder cancer (MIBC) undergoing radical cystectomy (RC), possibly through an increase in pathologic complete response (CR), defined as a pathologic stage T0 (pT0). We sought to identify predictors of CR for MIBC. Methods: The National Cancer Database from 2004 to 2013 was used to identify patients with cT2-4cN0cM0 urothelial cell carcinoma treated with RC. Patients were grouped based on pathology as CR (pT0), partial response (PR – pTa/Tis/T1) or no response (NR - pT2 or higher). Predictors of NAC and CR were identified with multivariable logistic regression. Cox proportional hazards model was used to compare OS based on cT stage, receipt of NAC and pathologic response. Results: The study population included 10,820 patients and NAC was administered in 16.4%. Use of NAC was associated with higher cT stage (p < 0.01) and increased over time (10% from 2003-2007 vs. 24% from 2011-2013, p < 0.01). Predictors of NAC use on multivariable analysis include younger age, lower comorbidity score, treatment at an academic center, and diagnosis from 2011-2013 (p < 0.01). Overall, CR was achieved in 3.3% without NAC and 16.3% with NAC (p < 0.01). NAC improved 5-year OS for all cT stages, however the survival benefit was only observed among those achieving CR (p < 0.01). Multivariable Cox regression demonstrates that both PR (HR 0. 58, p < 0.01) and CR (OR 0.26, p < 0.01) were independently associated with improved OS among those treated with NAC. Multivariable analysis identified age (OR 0.98, p < 0.01) and increased clinical stage (cT3: OR 0.47, p < 0.01; cT4 OR 0.54, p < 0.01) as negative predictors of CR. Utilization of NAC (OR 4.82 p < 0.01), academic institution, and diagnosis 2011-2013 (OR 1.92, p < 0.01) increased the odds of CR. Conclusions: Use of NAC increased over time and CR occurred in 16% of patients who received NAC. Treatment at an academic center, diagnosis from 2011-2013 and use of NAC were independently associated with CR, while increased age and clinical stage were negative predictors of CR. PR and CR are independently associated with improved OS relative to non-responders.
