BackgroundMuscle-invasive bladder cancer (MIBC) accounts for approximately 20% of all urothelial bladder carcinomas (UBC) at time of diagnosis, and up to 30% of patients with non-muscle invasive UBC will progress to MIBC over time. An increasing body of evidence has revealed a strong correlation between aberrant DNA methylation and tumorigenesis in MIBC.ResultsUsing The Cancer Genome Atlas (TCGA) molecular data for 413 patients, we described a DNA methylation-based signature as a prognostic factor for overall survival (OS) in MIBC patients. By using a least absolute shrinkage and selection operator (LASSO) model, differentially methylated regions were first identified using multiple criteria followed by survival and LASSO analyses to identify DNA methylation probes related to OS and build a classifier to stratify patients with MIBC. The prognostic value of the classifier, referred to as risk score (RS), was validated in a held-out testing set from the TCGA MIBC cohort. Finally, receiver operating characteristic (ROC) analysis was used to compare the prognostic accuracy of the models built with RS alone, RS plus clinicopathologic features, and clinicopathologic features alone. We found that our seven-probe classifier-based RS stratifies patients into high- and low-risk groups for overall survival (OS) in the testing set (n = 137) (AUC at 3 years, 0.65; AUC at 5 years, 0.65). In addition, RS significantly improved the prognostic model when it was combined with clinical information including age, smoking status, Tumor (T) stage, and Lymph node metastasis (N) stage.ConclusionsThe DNA methylation-based RS can be a useful tool to predict the accuracy of preoperative and/or post-cystectomy models of OS in MIBC patients.

e16530 Background: National Comprehensive Cancer Network (NCCN) guidelines state partial cystectomy (PC) may be offered in select patients with clinical T2 (cT2) muscle invasive bladder cancer (MIBC) utilizing neoadjuvant chemotherapy (NAC) and pelvic lymphadenectomy (PLND). Our objective was to investigate utilization and survival outcomes of PC in a large contemporary cohort. Methods: Propensity matching was used to compare pathological and surgical outcomes in non-metastatic MIBC patients in the National Cancer Database undergoing PC or radical cystectomy (RC). Multivariate logistic regression was used to determine predictors of NAC, LND, peri-operative morbidity and mortality outcomes. This analysis was repeated in the subset with cT2 MIBC. Results: Of 31,306 T2-T4N0M0 patients, 1543 (4.9%) underwent PC. PC use was higher in older patients and most often (85%) performed for cT2 disease. The PC group was less likely to receive standard of care including NAC (11.4 vs 27.9%, p<0.001) and PLND (58.7 vs 92.5%, p<0.001) than the RC group. Pathological ≥T3 disease (pT3) was found in 39.4% and pos. nodes in 6.9% of PCs. Positive margins were higher in PC, 15.7 vs 10.6%, p<0.001. PC patients had shorter inpatient stay (4.2 vs 8.7 days, p<0.001), lower 30-day readmission (6.7 vs 9.6%, p<0.001), and decreased 30- and 90-day mortality (1.3 vs 1.8%, p<0.001 & 4.8 vs 4.9%, p=0.04). PC was an independent predictor of lack of NAC (OR 0.49, p<0.001) and PLND (OR 0.11, p<0.001), shorter LOS (b -4.66, <0.001), readmission rate (OR 0.72, p<0.001), and improved 30- and 90- day mortality (OR 0.55 & 0.75, p<0.001). In cT2 patients only: PLND and NAC were less utilized in PC (p<0.001), 32% were ≥pT3 and 6.6% node pos. In both full cohort and cT2 subset, PC was associated with slight improvement in time to mortality (Table) and overall survival (OS) (OR 1.44, p<0.001). Conclusions: PC is rarely used in treatment of MIBC. Despite guidelines, NAC and PLND are underutilized in PC. Care is required in selecting patients for PC as up to one third of cT2 patients have ≥pT3. In these likely highly selected patients, PC had lower peri-operative mortality and comparable OS to RC. Selection bias may play a role in these results and further investigation is needed to determine optimal candidates for PC.[Table: see text]

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.

Non-muscle invasive bladder cancer (NMIBC), which is characterized by a recurrence rate of approximately 30% and very long treatment times, remains a major unresolved problem for patients and the health care system. The immunological interplay between tumor cells and the immune environment is important for tumor development. Therefore, we analyzed the mRNA of three immune markers, CXCL9, PD1 and PD-L1, in NMIBC by qRT-PCR. The results were subsequently correlated with clinicopathological parameters and prognostic data. Altogether, as expected, higher age was an independent prognostic factor for overall survival (OS) and disease-specific survival (DSS), but not for recurrence-free survival (RFS). Lower CXCL9 mRNA was observed in multivariate Cox’s regression analysis to be an independent prognostic parameter for reduced OS (relative risk; RR = 2.08; p = 0.049), DSS (RR = 4.49; p = 0.006) and RFS (RR = 2.69; p = 0.005). In addition, PD-L1 mRNA was an independent prognostic factor for DSS (RR = 5.02; p = 0.042) and RFS (RR = 2.07; p = 0.044). Moreover, in univariate Cox’s regression analysis, the stratification of patients revealed that low CXCL9 or low PD1 mRNA was associated with reduced RFS in the younger patient group (≤71 years), but not in the older patient group (>71 years). In addition, low CXCL9 or low PD-L1 was associated with shorter RFS in patients with higher tumor cell proliferation and in patients without instillation therapy. In conclusion, the characterization of mRNA levels of immune markers differentiates NIMBC patients with respect to prognosis.

428 Background: The prognostic benefit of oncological follow-up to detect asymptomatic recurrence after radical cystectomy (RC) remains unclear. We aimed to assess whether routine follow-up to detect asymptomatic recurrence after RC improves patient survival. Methods: We retrospectively analyzed 581 RC cases for muscle invasive bladder cancer at four hospitals between May 1996 and February 2017. All patients had regular follow-up examinations with urine cytology, blood biochemical tests, and computed tomography after RC. We investigated the first site and date of tumor recurrence. Overall survival in patients with recurrence stratified by the mode of recurrence (asymptomatic group vs. symptomatic group) was estimated using the Kaplan–Meier method with the log–rank test. Cox proportional hazards regression analysis via inverse probability of treatment weighting (IPTW) was used to evaluate the impact of the mode of diagnosing recurrence on survival. Results: Of the 581 patients, 175 experienced relapse. Among those, 12 without adequate data were excluded. Of the remaining 163 patients, 76 (47%) were asymptomatic and 87 (53%) were symptomatic at the time of diagnosis. The most common recurrence site and symptom were lymph nodes (47%) and pain (53%), respectively. Time of overall survival after RC and from recurrence to death were significantly longer in the asymptomatic group than symptomatic group. A multivariate Cox regression analysis using IPTW showed that in the patients with symptomatic recurrence was an independent risk factor for overall survival after RC and survival from recurrence to death. Conclusions: Routine oncological follow-up for detection of asymptomatic recurrence contributes to a better prognosis after RC.
