Background: To identify the hub genes related to urothelial carcinoma of the bladder prognosis and to understand their underlying mechanism. Methods: The expression profiles of 18 pairs of urothelial carcinoma of the bladder patient tissue and paired adjacent tissue obtained from the Cancer Genome Atlas were performed. Weighted gene coexpression network analysis was employed to screen gene modules and hub genes with significant differential expressions in urothelial carcinoma of the bladder. The hub genes expression in urothelial carcinoma of the bladder tissues was validated by reverse transcription-quantitative polymerase chain reaction. The overall survival curve and disease-free survival curve of prognostic factor ( LGALS4) were plotted using the Kaplan-Meier method. Furthermore, LGALS4 messenger RNA and protein expression were also assessed in 2 urothelial carcinoma of the bladder cell lines (T24 and 5637) by quantitative reverse transcription–polymerase chain reaction and Western blot. The functions of urothelial carcinoma of the bladder cells with transfected pcDNA3.1- LGALS4 were identified through MTT assay, plate clone formation assay, flow cytometry, and cell migration experiments. Results: LGALS4 was the hub gene of pink module and it was related to prognosis. Higher LGALS4 expression predicted higher probabilities of overall survival and disease-free survival. Overexpression of LGALS4 in urothelial carcinoma of the bladder cells suppressed cell viability and migration but induced apoptosis. Conclusion: LGALS4 played a critical role in the progression of urothelial carcinoma of the bladder and held a promise to be the biomarker for diagnosis and treatment of urothelial carcinoma of the bladder. It predicted good prognosis of urothelial carcinoma of the bladder and restrained the growth and migration of urothelial carcinoma of the bladder cells.

e16100 Background: The neoadjuvant M-VAC followed by radical cystectomy for muscle-invasive bladder cancer has improved survival compared to radical cystectomy alone. Nevertheless, M-VAC has been associated with severe toxicity. The objective of this retrospective study was to evaluate the objective response rate, the impact on overall survival, disease-free survival, disease-free survival and toxicity adverse events of gemcitabine and carboplatin (GC) neoadjuvant chemotherapy in patients with locally advanced bladder cancer. Methods: We reviewed the clinical and pathological data of 140 patients who underwent radical cystectomy and bilateral pelvic lymphadenectomy for T2N0M0 to T4aN0M0 bladder cancer at our institution between January 2001 and August 2008. Seventy patients were treated with neoadjuvant GC followed by cystectomy between March 2005 and August 2008 (GC group), and 70 patients were treated with cystectomy alone between January 2001 and May 2007 (cystectomy alone group). In the GC group, the patients received 2 courses of GC therapy consisted of 800mg/m2 gemcitabine on days 1, 8, and 15 and carboplatin (AUC 4) on day 2. The primary endpoint was the objective response rate, and the secondary endpoints were overall survival, cancer-specific survival, disease free survival, and toxicity. Results: Fifteen patients (23.8%) had a complete response and 26 patients (41.3%) had a partial response in the GC group. At a mean follow-up period of 26.7 months, the overall survival was 85.0% in the GC group and 47.8% in the cystectomy alone group (p = 0.003). The cancer-specific survival was 78.4% in the GC group and 44.6% in the cystectomy alone group (p = 0.0018). The disease-free survival was 82.9% in the GC group and 35.7% in the cystectomy alone group (p = 0.0001). Hematologic toxicities were the main adverse events. Grade 3/4 neutropenia occurred in 26 patients (37.1%) and thrombocytopenia in 15 (21.4%). There was no grade 3/4 gastrointestinal toxicity and no renal function abnormalities. Conclusions: Although this is not a randomized study, the GC neoadjuvant therapy followed by radical cystectomy is feasible and may be associated with improved survival among patients with muscle-invasive bladder cancer. A randomized trial is warranted. No significant financial relationships to disclose.

376 Background: Prospective randomized trials demonstrated efficacy of MVAC (Methotrexate, Vinblastine, Doxorubicin, Cisplatin) neoadjuvant chemotherapy (NAC) in muscle invasive bladder cancer (MIBC). In metastatic setting urothelial cell carcinoma (UCC), clinical trials showed no difference in oncologic outcomes between Gemcitabine-Cisplatin (GC) and MVAC, and another prospective trial proved dose-dense (dd) MVAC had significantly better overall survival (OS) and response rate then MVAC. Comparative data between GC and ddMVAC are limited in neoadjuvant setting. Methods: A retrospective analysis of patients with urothelial carcinoma (cT2-4aN0-1M0) who received NAC from January 2011 and December 2017 in Asan Medical Center was conducted. Patients who received GC were compared to patients received ddMVAC in terms of outcomes including downstaging ( < ypT2 and no N upstaging), pathologic complete response (pCR, ypT0N0), disease-free survival (DFS), and overall survival (OS) and tolerability. Results: In a total of 277 patients, 176 patients received NAC with GC and 41 patients with dose-dense MVAC. The median chemotherapy cycle is 4 (IQR 3-4) cycles for GC group, 4 (IQR 3-5.5) cycles for dose-dense MVAC group. With an exception of age; GC group is associated with younger age (p = 0.002), other baseline characteristics are well balanced between groups. Downstaging rate are 50.8% in GC group, 58.1% in dose-dense MVAC group (p = 0.47). The rates of achieving ypT0 (28.7% vs 22.6%, p = 0.68), ypN0 (78.3% vs 81.5%, p = 0.39). There were no differences in overall survival (OS) at 3 year (72.2% vs 73.2%, p = 0.58), disease-free survival (DFS) at 3 years (54.9% vs 63.3%, p = 0.21) according to chemotherapy regimens. ddMVAC with prophylactic G-CSF are associated with higher incidence of febrile neutropenia (p = 0.004) than GC. NAC regimen is not independent prognostic factor for OS on multivariable analysis. Conclusions: GC regimen had no significant difference in oncologic outcomes compare to ddMVAC as NAC in UCC.

Abstract PurposeTo develop and validate a prognostic nomogram in patients with bladder cancer who underwent radical cystectomy based on the Chinese population.MethodsThe nomogram was built on a retrospective study included 191 patients with bladder cancer who underwent radical cystectomy between January 2010 to December 2019 at the authors’ hospital. The primary cohort was divided into the training cohort and the validation cohort randomly. The endpoints in the study were disease-free survival and overall survival. The ability of distinguishing and predicting of the prognostic nomogram were determined by calibration plot and concordance index in the training cohort. Moreover, the results were also verified in the validation cohort internally.ResultsMultivariate analysis of the training cohort showed that hydronephrosis, Stage_T, Stage_N, PNI and EGFR were significantly associated with overall survival. Meanwhile, Stage_T, Stage_N, PNI and EGFR were independent risk factors for disease-free survival. The calibration plot agreed well between prediction and actual observation in survival possibility. The concordance index of the nomogram in the training cohort of overall survival and disease-free survival were 0.834 (95%CI: 0.785-0.833) and 0.823 (95%CI: 0.772-0.873), respectively. In the validation cohort, the nomogram also showed high predictive accuracy.ConclusionThe proposed nomogram showed high accuracy in predicting survival for bladder cancer patients after radical cystectomy.

585 Background: This study aims to compare oncologic outcomes among patients who underwent salvage radical cystectomy (sRC) for recurrent urothelial carcinoma (UC) of the bladder following radiotherapy (RT) with primary radical cystectomy (pRC). Methods: We retrospectively reviewed the data of 3705 primary consented cystectomy patients of our IRB-approved bladder cancer database from Jan 1971 to June 2017 who underwent radical cystectomy for urothelial carcinoma of the bladder. Clinical and pathological data at the time of both RT and RC was collected. Patients with non-UCs and those receiving radiation for non-UCs were excluded. Multivariate analyses was performed to identify prognostic factors after RC for overall survival and recurrence-free survival. Results: 3050 patients were identified who underwent radical cystectomy for UC of the bladder. Of these, 128 patients (4.2%) underwent sRC following radiotherapy (RT). Patient characteristics including age, BMI, gender, and comorbidities were similar between the groups. Complications rates between the groups were similar at 30 days (43% sRC vs 39% pRC patients, p=0.41) and 90 days (52% sRC vs 48% pRC, p=0.42). Patients receiving sRC were less likely to receive a continent diversion (p<0.001). Five-year overall survival following sRC was 47% in comparison to 63% for those undergoing pRC (p<0.001) (Fig 1). However, no significant difference in five-year recurrence free survival was found (61% sRC vs 68% pRC; p=0.15). On multivariate analysis, sRC (HR 1.37, p=0.048), pathologic tumor stage ≥pT3a (HR 2.6, P < 0.001) and lymph node metastases (HR 2.5, P < 0.001) were associated with increased risk of local recurrence after radical cystectomy. Conclusions: Patients undergoing sRC are less likely to receive a continent urinary diversion and are at increased risk of local recurrence following cystectomy in comparison to patients receiving primary cystectomy.
