<b><i>Objectives:</i></b> The aim of the study was to examine the effectiveness of a modified-short hydration gemcitabine and cisplatin (m-shGC) regimen for patients with metastatic urothelial carcinoma (mUC) and to assess the efficacy of a geriatric nutritional risk index (GNRI) with regard to prognosis. <b><i>Patients and Methods:</i></b> From January 2016 to July 2020, 68 patients with mUC underwent first-line m-shGC therapy with 70 mg/m<sup>2</sup> cisplatin and 1,000 mg/m<sup>2</sup> gemcitabine (days 1, 8, and 15), with 2,050 mL fluid replaced on the first day of each 28-day cycle. Prior to the start of treatment, the serum neutrophil-to-lymphocyte ratio (NLR), and levels of albumin and C-reactive protein (CRP) in serum, as well as body heights and weights were measured. Patients were grouped according to GNRI &#x3c;92 (low) or ≥92 (high). The analysis of data was done retrospectively. <b><i>Results:</i></b> Median follow-up was found to be 12.9 (range 1.7–50.2) months and the objective response rate (ORR) was 54.4% after m-shGC treatment. The ORR was significantly different when high and low-GNRI groups were compared (ORR: 28.0 vs. 69.8% in low- vs. high-GNRI groups). Median overall survival (OS) was calculated as 8.6 (95% confidence interval [CI]: 5.4–21.3) and 34.5 (95% CI: 20.5–NA) months for low- and high-GNRI groups, respectively (<i>p</i> &#x3c; 0.0001). Unlike for NLR and CRP, univariate and multivariate analyses revealed that low GNRI and visceral metastases were significant prognostic factors for short OS. <b><i>Conclusions:</i></b> First-line m-shGC showed a survival benefit for mUC, with GNRI a useful prognostic biomarker.

409 Background: In the current study, we evaluated whether the response first-line chemotherapy could impact atezolizumab benefit in terms of response rate and overall survival in patients with metastatic urothelial carcinoma. Methods: In this study, we present the retrospective analysis of 105 patients with urothelial cancer treated with ATZ after progression on first-line chemotherapy. The association between response to first-line chemotherapy and ATZ was assessed using Fisher’s exact test. Overall survival (OS) was estimated by using the Kaplan-Meier method. Univariate analysis was used to identify clinical and laboratory factors that significantly impact OS. Variables were retained for multivariate analysis if they had a statistical relationship with OS (p˂0.1) and then included the final model if p˂0.05. Results: Best response to first-line chemotherapy was complete response (CR), partial response (PR), stable disease (SD) and progressive disease (PD) in 5(4.8%), 38(36.2%), 16(15.2%), 46(43.8%) patients, respectively. Best response to atezolizumab was CR, PR, SD, PD in 9(8.6%), 22(21%), 23(21,9%), 51(48,5%). Forty (74.1%) of patients who benefited from first-line chemotherapy also benefited from atezolizumab, while only 14 (25.9%) of patients with initial PD after first-line chemotherapy subsequently experienced clinical benefit with atezolizumab (Fisher’s exact test, p=0.001). Patients with clinical benefit from first-line chemotherapy had a higher OS. The median OS of atezolizumab were 14.8 and 3.4 months for patients with clinical benefit and progressive disease in response to first-line chemotherapy, respectively (log-rank p=0.001). In univariate analysis, Patients with clinical benefit from first-line chemotherapy, liver metastases, baseline creatinine clearance less (GFR)than 60 ml/min, Eastern Cooperative Oncology Group (ECOG) performance status (1 ≥), and hemoglobin levels below 10 mg/dl were all significantly associated with OS. Three of the adverse prognostic factors according to the Bellmunt criteria were independent factor of short survival: liver metastases (Hazard Ratio [HR]= 0.6; 95% CI 0.174-0.60; p=0.04), ECOG PS≥1 (HR= 0.36; 95% CI 0.2-0.66; p=0.001), and Hemoglobin level below 10 mg/dl (HR= 0.36; 95% CI 0.2-0.66; p <0.001). In addition, Patients with clinical benefit from first-line chemotherapy (HR= 0.39; 95% CI 0.24-0.65; p <0.001) maintained a significant association with OS in multivariate analysis. Conclusions: Our study demonstrated that clinical benefit from first-line chemotherapy was independent prognostic factor on OS in patients' use of atezolizumab as second-line treatment in metastatic bladder cancer. Furthermore, these findings are important for stratification factors for future immunotherapy study design in patients with bladder cancer who have progressed after first-line chemotherapy.

13511 Background: Treatment until progression or planned interruption of first line chemotherapy is common in the therapy for metastatic colorectal cancer and are upon the discretion of the oncologist. A retrospective analysis was performed to determine the impact of these differing therapeutic strategies on overall survival. Methods: Eligible patients were treated between 2002 to 2004 in British Columbia. All patients received chemotherapy with both FOLFOX and FOLFIRI, either first or second line. Records were retrospectively reviewed for treatment interruption, efficacy and toxicity. Overall survival was the primary endpoint. Results: 101 patients were identified. Twenty-three patients who progressed before receiving 8 cycles of chemotherapy and 9 patients who stopped their chemotherapy due to toxicity were excluded. The remaining patients were analyzed for survival. Twenty-three patients were treated to progression of whom 6 received first line FOLFIRI and 17 received first line FOLFOX. The mean number of cycles of first line therapy was was 11.5. Forty six patients received a planned break. Of these, 21pateints received first line FOLFIRI and 25 patients received first line FOLFOX. Mean number of cycles of first line therapy was 9.7. Median survival of patients treated to progression was 16 months compared to 22 months for patients with planned break of therapy (p=0.003). The Hazard ratio was 2.3 (p=0.01) in favor of patients who had a planned break. Uni-variate and multivariate analysis showed no significance of sex, age, site (colon versus rectal), sequence and ECOG status as predictive factors. Conclusion: In this study, patients who were treated until progression with first line chemotherapy with either FOLFOX or FOLFIRI had an inferior survival. Possible explanations for the detrimental hazard ratio for patients treated to progression are decreasing reserve for second line therapy when first line therapy is prolonged and increasing resistance to 5-FU based therapy with prolonged exposure. As this is a retrospective, observational study, other variables not captured by the modeled covariates that may have influenced results. This data suggests that treating to best response and then allowing a break does not detrimentally affect survival. No significant financial relationships to disclose.

e15613 Background: Despite high response rates (RRs) with first-line platinum-based chemotherapy in advanced urothelial carcinoma (UCC), treatment after first-line failure remains unclear. The present multi-center phase II trial evaluated the tolerability and efficacy of weekly docetaxel as second-line chemotherapy for UCC. Methods: Between Aug 2010 and Sep 2012, 31 patients with measurable UCC, progressive after one prior platinum-based chemotherapy for advanced disease, were treated with docetaxel 30 mg/m2 on days 1 and 8. Treatment was repeated every 21 days until disease progression or unacceptable toxicity. The primary endpoints were the RR, progression-free survival (PFS), and safety. To detect a 20% difference in RR (6% vs. 26%), 28 eligible patients were required. Results: All 31 patients were previously treated with gemcitabine/platinum and had Bellmunt risk of one or more. The patients’ median age was 64 years (range, 40 to 79) and 31 (100%) patients had an ECOG performance status of 1. A total of 106 (median, 2; range, 1 to 16) chemotherapy cycles were delivered. Although fatigue (13%) and anorexia (6%) were the most frequently observed grade 3 or 4 toxicities, safety profiles were generally mild and manageable. One patient developed prolonged thrombocytopenia which led to treatment discontinuation but was resolved thereafter. In an intent-to-treat analysis, two (6%) patients achieved objective response, which maintained for 3.0 to 7.8 months. Eight patients experienced disease stabilization, resulting in a disease control rate of 32%. The median PFS and overall survival were 1.4 (95% CI, 1.3 to 1.6) and 9.6 (95% CI, 7.8 to 11.4) months, respectively. Conclusions: Second-line chemotherapy with weekly docetaxel was well tolerated but demonstrated modest antitumor activity in patient with advanced UCC who had progression after first-line platinum-containing regimen and poor prognostic factors. Clinical trial information: NCT01711112.

TPS187 Background: Outcomes for patients with advanced OG cancer remain poor, median overall survival for fit patients treated with platinum and fluoropyrimidine based chemotherapy is less than one year, with second line chemotherapy resulting in a modest (approximately 6 weeks) survival benefit for selected patients. Evidence from NSCLC trials suggests a survival benefit from maintenance treatment following first line chemotherapy. Emerging data also supports the use of immunotherapy in previously treated OG cancer. The PLATFORM study aims to evaluate maintenance therapy in patients with advanced OG cancer. Methods: This is a prospective, open label, multicentre, randomised phase II clinical trial which will recruit at multiple UK cancer centres. Eligible patients are those who have measurable stable disease or better following completion of first line chemotherapy (at least 6 cycles) for locally advanced unresectable or metastatic disease. First line chemotherapy regime should contain a platinum and 5-fluoropyridimine (with trastuzumab if HER2 +), doublet or triplet drug combinations are permitted. Maintenance strategies are split by HER 2 status. For HER2 negative patients these are: Arm A1: surveillance, Arm A2: capecitabine, Arm A3: MEDI 4736 (anti PDL1 inhibitor) and for HER2 positive patients; Arm B1: trastuzumab, Arm B2: in development. Target recruitment is six hundred and sixteen patients, 154 patients will be recruited to each arm, with an interim analysis following recruitment of 61 patients to each arm. An adaptive trial design enables ineffective treatments to be discontinued early, with the opportunity to add novel treatment arms as the trial progresses. Primary endpoint is progression free survival. Secondary endpoints are progression free rate at 3, 6 & 12 months, overall survival, objective response rate by RECIST 1.1, toxicity and analysis of efficacy endpoints according to biomarker status for selected arms. Thirty two patients have been registered for the study with 3 patients randomised, recruitment is ongoing. Clinical trial information: EUDRACT: 2014-002169-30.

e17019 Background: Based on our previous study, the systemic immune-inflammation index (SII) is a prognostic factor in patients with metastatic urothelial cancer (MUC) treated with platinum-based first-line chemotherapy. The objective of this retrospective analysis was to explore prognostic value of the SII at baseline of second-line chemotherapy with vinflunine in MUC population. Methods: We evaluated 70 consecutive MUC (53 bladder, 21 upper tract) patients (54 men) treated with second-line chemotherapy with vinflunine at four oncological departments since 2010. ECOG performance status (PS) ≤ 1 had 44 patients (pts.), haemoglobin < 10 g/dL was present in 25 pts. and liver involvement in 18 pts. SII was based on platelets (P), neutrophils (N) and lymphocytes (L) counts defined as PxN/L. This study population was dichotomized by median into low SII and high SII groups. Progression-free survival (PFS), overall survival (OS) and their 95% CI were estimated by Kaplan-Meier method and compared with logrank test. Results: At median follow-up of 9.0 months (1-29 months), 68 pts. experienced disease progression and 62 died. Pts. with low SII at baseline had significantly better PFS and OS opposite to those with high SII (HR = 0.61, 95% CI 0.37-1.00, p = 0.0318 for PFS, HR = 0.60, 95% CI 0.36-1.00, p = 0.0312 for OS, respectively). In addition to the prognostic factors by Bellmunt (ECOG PS ≥ 1, liver involvement, haemoglobin < 10 g/dL), we identified peritoneal metastases as a factor associated with significantly worse survival (HR = 0.28, 95% CI 0.11-0.72, p < 0.00001 for PFS, HR = 0.30, 95% CI 0.12-0.75, p < 0.00001 for OS, respectively). Conclusions: The SII at baseline of treatment with second-line vinflunine represents a prognostic factor for pts. with MUC. Based on SII, pts. could be stratified into clinical trials in future. MUC pts. with high SII might be candidates for a different treatment approach. Key Words: Metastatic Urothelial Carcinoma. Systemic Immune-Inflammation Index. Vinflunine. Progression-Free Survival.
