373 Background: Butyrylcholinesterase (BChE) is an alpha-glycoprotein found in the nervous system and liver. Its serum level is reduced in many clinical conditions, such as liver damage, inflammation, injury, infection, malnutrition, and malignant disease. In this study, we analyzed the potential prognostic significance of preoperative BChE levels in patients with muscle-invasive bladder cancer (MIBC) undergoing radical cystectomy (RC). Methods: We retrospectively evaluated 327 patients with MIBC who underwent RC from 1996 to 2013 at a single institution. Serum BChE was routinely measured before operation in all patients. Covariates included age, gender, preoperative laboratory data (anemia, BChE, lactate dehydrogenase, C-reactive protein), clinical T (cT) and N stage (cN), tumor grade, and RC with/without neoadjuvant chemotherapy. Univariate and multivariate analyses were performed to identify clinical factors associated with overall (OS) and disease-free survival (DFS). Univariate analyses were performed using the Kaplan-Meier and log-rank methods, and the multivariate analysis was performed using a Cox proportional hazard model. Results: The median BChE level was 187 U/L (normal range, 168–470 U/L). The median age of the enrolled patients was 69 years, and the median follow-up period was 51 months. The 5-year OS and DFS rates were 69.6% and 69.3%, respectively. The 5-year OS rates were 90.1% and 51.3% in the BChE ≥ 168 and < 168 U/L groups, respectively (P < 0.001). The 5-year DFS rates were 83.5% and 55.4% in the BChE ≥ 168 and ≤ 167 U/L groups, respectively (P < 0.001). In the univariate analysis, BChE, cT, cN, and RC with/without neoadjuvant chemotherapy were significantly associated with both OS and DFS. Multivariate analysis revealed that BChE was the factor most significantly associated with OS, and BChE, cT, and cN were significantly associated with DFS. Conclusions: This study validated preoperative serum BChE levels as an independent prognostic factor for MIBC after RC.

361 Background: Prognosis and tumor responses of carboplatin-based neoadjuvant chemotherapy for muscle invasive bladder cancer (MIBC) are not well documented. To assess the usefulness of carboplatin-based neoadjuvant chemotherapy, we examined the correlation between radiological responses and pathologic down staging on radical cystectomy (RCx) specimens, disease free survival (DFS), and overall survival (OS). Methods: Between March 2005 and June 2013, we performed carboplatin-based neoadjuvant chemotherapy followed by radical cystectomy in 115 patients with T2-4NxM0 MIBC. After diagnostic TUR biopsy, all participants received two courses of Gemcitabine plus Carboplatin therapy. Baseline and post chemotherapy tumor size from contrast enhanced CT were reviewed. The patients were divided in two groups between responders (CR+PR), and non-responders (SD+PD). RCx and bilateral pelvic lymphadenectomy were performed approximately within a month after cessation of chemotherapy. DFS and OS distributions within radiologic response subgroups were estimated with the Kaplan-Meier method and compared using the log-rank test. To evaluate independent predictor for DFS and OS, age, gender, performance status, pathological T and N stage, down-staging, tumor grade, renal function, and radiological responses were applied by Cox-regression multivariate analysis. Results: No significant differences were observed in patient backgrounds between the groups. Radiologic responses were observed in 75 (65%) patients with 69±24% decrease in responder group, whereas tumor response was 2.8±14% in non-responders. The rate of pathological down staging to <pT2 was 37 (49%) in responders, 5 (13%) in non-responders group. Radiologic response was a strong predictor of DFS and OS. A 5-year advantages of DFS and OS in responders vs. non-responders were 88% and 86% vs. 64% and 69%, respectively (P=0.021 and P=0.013). Multivariate analysis showed radiologic response was the independent factor for DFS and OS. Conclusions: Radiological response post carboplatin-based neoadjuvant chemotherapy is associated with OS in patients with MIBC.

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.

PURPOSE To determine survival in patients with muscle-invasive bladder cancer treated with neoadjuvant chemotherapy and to analyze prechemotherapy and postchemotherapy factors for prognostic significance. PATIENTS AND METHODS The survival of 111 patients with T2-4N0M0 bladder cancer treated with neoadjuvant methotrexate, vinblastine, doxorubicin, and cisplatin (M-VAC) was assessed. Prechemotherapy and postchemotherapy factors were analyzed for correlation with survival. Factors found to be significant on univariate analysis were subjected to multivariate analysis using Cox's proportional hazards model. RESULTS The median follow-up duration was 5.3 years. Initial tumor (T) stage (P = .0001), presence of ureteral obstruction (P = .0074), and presence of a palpable mass (P = .0039) were the only pretreatment factors found to be significant on univariate analysis. Postchemotherapy surgery was performed in 81 patients. In these cases, postchemotherapy clinical stage and pathologic stage were significant factors on univariate analysis. In the multivariate analysis, the initial prechemotherapy T stage and the postchemotherapy pathologic stage (pT stage) were the only two factors to demonstrate independent significance. An association between downstaging postchemotherapy and survival was observed for patients with extravesical disease (T < or = 3B) at the start of treatment. In this subset, the 5-year survival rate was 54% for patients with downstaging versus 12% for those without downstaging. This association was not observed for patients with bladder-confined disease (T < or = 3A) at presentation. CONCLUSION The stage of bladder cancer at presentation and at postchemotherapy pathologic staging are independent prognostic factors for long-term survival in patients treated with neoadjuvant chemotherapy. Downstaging after neoadjuvant chemotherapy was associated with improved survival in patients with muscle-invasive bladder cancers, but only for those with extravesical disease (T > or = 3B) pretreatment. Randomized comparisons will be required to assess the impact of chemotherapy on overall survival.
