To evaluate oncological outcomes of primary versus secondary muscle-invasive bladder cancer treated with radical cystectomy. Medline, Embase, Scopus and Cochrane Library were searched for eligible studies. Hazard ratios for overall survival (OS), cancer specific survival (CSS) and progression free survival (PFS) were calculated using survival data extracted from Kaplan-Meier curves. A total of 16 studies with 5270 patients were included. Pooled analysis showed similar 5-year and 10-year OS (HR 1, p = 0.96 and HR 1, p = 0.14) and CSS (HR 1.02, p = 0.85 and HR 0.99, p = 0.93) between primMIBC and secMIBC. Subgroup analyses according to starting point of follow-up and second-look transurethral resection revealed similar results. Subgroup analyses of studies in which neoadjuvant chemotherapy was administered demonstrated significantly worse 5-year CSS (HR 1.5, p = 0.04) but not 10-year CSS (HR 1.36, p = 0.13) in patients with secMIBC. Patients with secMIBC had significantly worse PFS at 5-year (HR 1.41, p = 0.002) but not at 10-year follow-up (HR 1.25, p = 0.34). This review found comparable oncologic outcomes between primMIBC and secMIBC patients treated with RC regarding OS and CSS. Subgroup analysis showed worse 5-year CSS but not 10-year CSS for neoadjuvant chemotherapy in the secMIBC group. Prospective clinical trials incorporating molecular markers, that allow precise risk stratification of secMIBC and further research uncovering underlying molecular and clinical drivers of the heterogeneous group of secMIBC is needed.

e17036 Background: The standard treatment for Muscle Invasive bladder cancer (MIBC),Radical Cystectomy and Neoadjuvant chemotherapy (NACT) has shown to improve survival. Data from Indian population is scarce, and we sought to explore the efficacy, tolerability and factors affecting the outcome of Neoadjuvant chemotherapy in our population. Methods: This was a Retrospective Observational study conducted at a tertiary care centre. Patients of MIBC treated between 2008 and 2019 were included in the analysis. The NACT consisted of Gemcitabine + Cisplatin (GC) or Gemcitabine + Carboplatin (GCa). The prognostic significance of the various clinico-laboratory parameters was assessed by the log rank test. The survival analysis was done by the Kaplan Meier method. Results: Total of 40 patients received NACT from 2008-2019. The median age of study group was 62 years. Male to Female ratio was 5:1. Out of 40 patients, 26 were treated with GC and the remaining 14 received GCa. Majority (80%) patients were administered either 3 or 4 cycles of NACT. Among 18 patients who demonstrated good radiological response after NACT completion, 13 had received Cisplatin. After NACT, 32 (80%) underwent Radical Cystectomy and 3 were treated with CTRT. The remaining 5 did not receive definitive treatment. Pathological complete response (PCR) was achieved in 10 out of 32 patients (31%). Out of 10 patients with PCR, 9 belonged to Cisplatin group and only 1 in Carboplatin group. In patients with PCR, 80% remained progression free at last follow up. Grade 3/4 toxicities were minimal. However, achieving a pathological CR did not translate into significant survival benefit in our study (p value 0.10). Median follow up time and overall survival for the cohort was 29.5 and 54 months respectively. Conclusions: Gemcitabine/Cisplatin as NACT resulted in superior radiological response, PCR, PFS and OS when compared to Gemcitabine/Carboplatin in MIBC. This regimen is well tolerated and we advocate for further prospective studies with GC in this setting. [Table: see text]

Introduction: BCG and MMC shortage and Covid-19 pandemic, more recently, limit accessibility to maintenance regimen in intravesical prophylaxis against recurrence of non-muscle invasive bladder cancer (NMIBC). Ellagic acid (EA) and Annona muricata (AM) exert antitumor activity against different human tumours. An observational prospective study on the prophylactic effect of oral administration of EA+AM in patients avoiding maintenance regimen is presented. Materials and methods: Patients affected by NMIBC and not undergoing maintenance after a 6-week course of intravesical prophylaxis with MMC or BCG were entered. Tis and very high-risk tumours were excluded. After informed consent, the patients were subdivided in relation to the oral assumption or not of EA (100 mg) plus AM (100 mg), daily for 6 months. All patients were submitted to 3-month cytology and cystoscopy. Results: 162 (90%) of 180 entered patients are evaluable, 90 and 72 receiving or not EA+AM. No difference emerged in patients’ characteristics between the two groups. BCG was given in 86 (54%) and chemotherapy in 74 (46%) patients. The recurrence free rate at 3, 6 and 12 months in patients assuming or not EA was 96.5% versus 84.6% ( p = 0.003), 85.4% versus 64.8% ( p = 0.005) and 74.2% versus 60.6% ( p = 0.246), respectively. The recurrence free survival at 12 months in patients assuming or not EA was 63.0% versus 34.5% ( p < 0.0001). Discussion and conclusions: Our study suffers several limits: not randomized trial although prospective, limited number of patients and short follow-up, nevertheless it shows the prophylactic effect of oral EA+AM in absence of maintenance after intravesical chemotherapy or immunotherapy induction.
