Abstract Purpose To evaluate the prognostic value of the aspartate transaminase/alanine transaminase (AST/ALT) ratio in primary non-muscle-invasive bladder cancer (NMIBC) using propensity score matching (PSM) analysis. Methods We retrospectively collected the clinical and pathological data from 314 patients with primary NMIBC who underwent transurethral resection of bladder tumor. The full cohorts were divided into a low AST/ALT ratio group and a high AST/ALT ratio group according to the optimal cut-off value which was obtained based on the analysis of the receiver operating characteristic curve for the 3-year recurrence-free survival (RFS). After 1:1 PSM, the correlation between preoperative AST/ALT ratio and survival prognosis was evaluated by Kaplan–Meier analysis with log-rank tests. The independent prognostic factors for RFS and progression-free survival (PFS) were also analyzed. Results The optimum cutoff value of the preoperative AST/ALT ratio was 1.40. Before PSM, a high AST/ALT ratio was correlated with the larger proportion of age > 60 years (P = 0.007) and the worse pathological T stage (P < 0.001). After PSM, patients with a high AST/ALT ratio had poorer RFS and PFS than patients with a low AST/ALT ratio (all P < 0.001). In addition, multivariate Cox regression analysis indicated that preoperative AST/ALT ratio was considered as an independent prognostic factor of RFS (HR 2.865; 95%CI 1.873–4.381; P < 0.001) and PFS (HR 4.771; 95%CI 2.607–8.734; P < 0.001) in patients with primary NMIBC. Conclusions The high AST/ALT ratio group tended to have poorer RFS and PFS than the low AST/ALT ratio group. Our results also indicated that the elevated preoperative AST/ALT ratio could be seen as a useful prognostic biomarker for predicting early disease recurrence and progression in patients with primary NMIBC.

Abstract Background To explore possible solutions to overcome chronic Bacillus Calmette–Guérin (BCG) shortage affecting seriously the management of non-muscle invasive bladder cancer (NMIBC) in Europe and throughout the world, we investigated whether non-maintenance eight-dose induction BCG (iBCG) was comparable to six-dose iBCG plus maintenance BCG (mBCG). Methods This observational study evaluated 2669 patients with high- or highest-risk NMIBC who treated with iBCG with or without mBCG during 2000–2019. The patients were classified into five groups according to treatment pattern: 874 (33%) received non-maintenance six-dose iBCG (Group A), 405 (15%) received six-dose iBCG plus mBCG (Group B), 1189 (44%) received non-maintenance seven−/eight-dose iBCG (Group C), 60 (2.2%) received seven−/eight-dose iBCG plus mBCG, and 141 (5.3%) received only ≤5-dose iBCG. Recurrence-free survival (RFS), progression-free survival, and cancer-specific survival were estimated and compared using Kaplan–Meier analysis and the log-rank test, respectively. Propensity score-based one-to-one matching was performed using a multivariable logistic regression model based on covariates to obtain balanced groups. To eliminate possible immortal bias, 6-, 12-, 18-, and 24-month conditional landmark analyses of RFS were performed. Results RFS comparison confirmed that mBCG yielded significant benefit following six-dose iBCG (Group B) in recurrence risk reduction compared to iBCG alone (groups A and C) before (P < 0.001 and P = 0.0016, respectively) and after propensity score matching (P = 0.001 and P = 0.0074, respectively). Propensity score-matched sequential landmark analyses revealed no significant differences between groups B and C at 12, 18, and 24 months, whereas landmark analyses at 6 and 12 months showed a benefit of mBCG following six-dose iBCG compared to non-maintenance six-dose iBCG (P = 0.0055 and P = 0.032, respectively). There were no significant differences in the risks of progression and cancer-specific death in all comparisons of the matched cohorts. Conclusions Although non-maintenance eight-dose iBCG was inferior to six-dose iBCG plus mBCG, the former might be an alternative remedy in the BCG shortage era. To overcome this challenge, further investigation is warranted to confirm the real clinical value of non-maintenance eight-dose iBCG.

<b><i>Objective:</i></b> This study aimed to compare the survival outcomes between trimodal therapy (TT) and partial cystectomy (PC) in muscle-invasive bladder cancer (MIBC) patients. <b><i>Methods:</i></b> The data of 13,096 patients with MIBC diagnosed between 2004 and 2015 were retrieved from the Surveillance, Epidemiology, and End Results database. Among them, 4,041 patients underwent TT and 1,670 patients underwent PC. Propensity score matching was performed to balance the characteristics between the 2 treatment groups. A multivariate Cox regression analysis model and a competing risk model were used to evaluate overall survival (OS) and cancer-specific survival. Cumulative incidence survival curves were obtained using the Kaplan-Meier method. <b><i>Results:</i></b> Results of multivariate Cox analysis before propensity score matching showed that the TT group had a 31% reduction in cause-specific survival relative to the PC group (HR: 0.69, 95% CI: 0.61–0.78, <i>p</i> &#x3c; 0.001) and a 28% reduction in OS (HR: 0.72, 95% CI: 0.66–0.79, <i>p</i> &#x3c; 0.001). After propensity score matching, the 2 groups yielded 972 patients, with 3-year cause-specific survival rates of 54.1% and 68.5% in the TT group and the PC group, respectively. <b><i>Conclusions:</i></b> Patients who underwent PC had a better prognosis than those who received TT. In addition, for MIBC patients who required bladder-sparing therapy, advanced age (≥80 years), pathological type of squamous cell carcinoma, and tumor stage of T3–4, N2–3, and M1 were independent poor prognostic factors.

Abstract In patients with various cancers, modified Glasgow prognostic score (mGPS) before treatment has predicted prognoses after antitumor therapy. This study aimed to assess whether pretreatment mGPS also has predictive value in patients with muscle-invasive bladder cancer (MIBC) after radiotherapy. A retrospective review accumulated 98 consecutive MIBC patients treated with definitive 3D-conformal radiotherapy from January 2011 to December 2016 in a single center. It included cT2-4bN0-3M0 patients with a median age of 79 years (range: 49 to 95 years). Radiotherapy was delivered at 60–66 Gy for bladder cancer. Patients were categorized in terms of their pretreatment serum albumin and C-reactive protein (CRP) values as mGPS_0, mGPS_1, and mGPS_2. Among them, cumulative overall survival (OS) rates were compared by Kaplan–Meier plots with log-rank tests. The number of patients with mGPS_0, mGPS_1, and mGPS_2 were 40, 40, and 18, respectively. The median follow-up time for all patients was 19 months (range: 2–73 months). The 2-year OS rate for all patients was 75.7%. The 2-year OS rates for mGPS_0, mGPS_1, and mGPS_2 were 85.1%, 71.3%, and 60.9%, respectively. Kaplan–Meier curves revealed a significantly higher cumulative OS rate for mGPS_0 compared with mGPS_1 and mGPS_2 (P = 0.003). Using multivariate Cox regression analysis, mGPS_0 and good performance status were associated with favorable OS rates, of which mGPS_0 was more significant (Hazard ratio 2.74, 95% CI 1.30–5.57, P = 0.008). Modified Glasgow prognostic score may be a novel biomarker that can predict survival in patients with MIBC after radiotherapy.

294 Background: Combination chemotherapy is the standard of care for neoadjuvant, adjuvant, and metastatic bladder cancer due to increased efficacy when compared to monotherapy. We report our experience with sequential intravesical combination chemotherapy using gemcitabine and mitomycin C (MMC) for non-muscle invasive bladder cancer (NMIBC). Methods: We performed a multi-institutional retrospective review of 47 consecutive patients who received 6 weekly treatments with sequential gemcitabine (1g) and mitomycin C (40mg) chemotherapy for NMIBC. Thirty patients received treatment at University of Iowa, 14 at UCSF and 3 at University of Minnesota. Results: A total 47 patients (median age 70, range 32-85; 36 males, 11 females) previously failing a median of 2 intravesical treatments were reviewed. The complete response (CR), 1-year recurrence-free survival (1-RFS) and 2-year recurrence-free survival (2-RFS) for all patients was 68%, 48% and 38%, respectively. In all, 14 of 47 patients (30%) remain free of recurrence with a median time to followup of 26 months (range 6-80 months). The median time to recurrence for all patients who recurred was 4 months (range 1-33 months). Ten patients required cystectomy. Conclusions: Sequential intravesical combination chemotherapy using gemcitabine and MMC appears to be a useful treatment for patients with a history of NMIC which has failed BCG or other intravesical therapy, in addition to patients with intermediate and high-risk disease.
