376 Background: Histological variants of urothelial carcinoma (UC) of the bladder have a poorer prognosis than histologically pure UC, and the role of neoadjuvant chemotherapy (NAC) in this group is unclear. Our objective was to evaluate NAC practice patterns and survival outcomes in patients with histologic variants undergoing radical cystectomy (RC). Methods: Patients with cT2-4N0-3M0 muscle invasive bladder cancer (MIBC) who underwent RC from 2003-2012 were selected from the National Cancer Database (NCDB). Patients were categorized by histology code as pure UC or histologic variants. Adjusting for patient and clinical characteristics, generalized estimating equations were used to test the association between histology and receipt of NAC. The association between receipt of NAC and overall survival (OS) was evaluated using Kaplan Meier curves and Cox regression models. Results: In 19,976 patients meeting inclusion criteria, receipt of NAC in histologic variants was less (11-14%) than in pure UC (22%), with the exception of micropapillary disease (23%) (Table). Median OS was lower in variant histologies than for pure UC (8.4 – 30.2 vs. 37.6 months). Receipt of NAC was associated with improved survival compared to RC or RC+adjuvant chemotherapy in patients with pure UC (HR 0.91, p=0.0016). There was no evidence of a survival benefit for NAC in the variant histologies, or that treatment effects differed by histology (P-val for interaction=0.84). Conclusions: In the NCDB, a substantial proportion of patients (13%) with histologic variants of MIBC undergoing RC receive NAC in the absence of a proven survival benefit. Clinical trials inclusive of patients with variant histologies are necessary to elucidate the role of NAC prior to RC. [Table: see text]

318 Background: Muscle invasive bladder cancer (MIBC) is a chemo-sensitive disease that responds to therapy before or after curative-intent radical cystectomy (RC). Neoadjuvant chemotherapy (NAC) improves overall survival by 5-8% in current meta-analyses. Adjuvant chemotherapy (AC) has shown benefit but is less rigorously tested. Methods: We retrospectively reviewed the cystectomy database at our institute from 2005-2011 and analyzed patients who have received NAC or AC for MIBC. The Log rank test was used to compare survival between groups and Cox regression models were used for adjusted comparisons of survival. Results: 45 patients (p) (13 NAC and 32 AC) were evaluated with a mean age of 65.5 years (50-82), including 77% males and 23% females. Patients were most commonly offered chemotherapy because of co-morbidities and performance status. NAC was most commonly gemcitabine (G)/cisplatin (n=9) and AC was usually G/platinum (n=27). Sixty-nine percent of patients were downstaged and 23% had a complete pathologic response following NAC. Three p in AC group had positive margins; all of these cases were T4 cancers. Pathologic staging showed 84% ≥T3 and 53% node positive disease. Patients receiving AC had a mean interval of 64.8 days (42-129) to the start of treatment. NAC and AC patients received median 4.1 (3-7) and 4.5 cycles (1-12), respectively, throughout entire course of treatment. The median overall survival (OS) was 24.5 months (m) (17.1 m-not reached) and 24-month survival rate was 47%. Progression free survival (PFS) was 12.3 m (8.5-23.5 m) for all patients. There was no difference for OS or PFS based on age, gender, time after surgery to first dose of therapy, or mode of therapy (NAC or AC). When adjusted for number of cycles completed, a trend toward improved median OS (not reached vs. 22 m p= 0.092 ) and a significant PFS improvement (28.5 vs 11.5 m p=0.026) with NAC vs. AC was observed. Grade 3-4 urologic toxicity was negligible in both groups, however the AC group had a higher percentage of grade 3-4 hematologic toxicity. Conclusions: Despite a small sample size, results from our series favor NAC based upon efficacy and tolerability for patients with locally invasive bladder cancer.

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.

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.

Introduction: Radical cystectomy (RC) is the main treatment option for patients with muscle-invasive bladder cancer (MIBC) and non-muscle-invasive bladder cancer (NMIBC), which carry the highest risk of progression. In this study, we investigated the effect of time from transurethral resection of the bladder (TUR-B) to cystectomy on lymph node positivity, cancer-specific survival and overall survival in patients with MIBC. Methods: The records were reviewed of 530 consecutive patients who had RC and pelvic lymphadenectomy procedures with curative intent performed by selected surgeons between May 2005 and April 2016. Our analysis included only patients with transitional cell carcinoma of the bladder; we excluded 23 patients with other types of tumor histology. Results: Patients who underwent delayed RC were compared with patients who were treated with early RC; both groups were similar in terms of age, gender, T stage, tumor grade, tumor differentiation, lymph node status and metastasis status. However, when both groups were compared for disease-free survival and overall survival, patients of the early-RC group had a greater advantage. Conclusions: The optimal time between the last TUR-B and RC is still controversial. A reasonable time for preoperative preparation can be allowed, but long delays, especially those exceeding 3 months, can lead to unfavorable outcomes in cancer control.
