In recent years,patient-derived tumor organoid(PDTO)models have rapidly emerged as important tools in cancer research,thanks to their unique ability to preserve the characteristics of primary tumors.These models provide a reliable preclinical research platform for screening individualized chemotherapy and targeted therapies for patients.However,traditional PDTOs lack immune cells and cannot replicate the tumor immune microenvironment,which restricts their utility in evaluating immunotherapies.To address this challenge,researchers have developed composite models that incorporate both tumor cells and immune cells,known as patient-derived immunocompetent tumor organoids(PDITOs).PDITOs have shown excellent performance in the preclinical evaluation of immunotherapies,particularly with PD-1/PD-L1 immune checkpoint inhibitors,with some studies reporting up to 100%accuracy in predicting patient responses to immunotherapy.As a common malignancy of the urinary system,bladder cancer has benefited from the application of PDITOs in drug screening and personalized immunotherapy evaluation,demonstrating significant potential.This paper aims to review the rise and development of PDITOs,and compare the advantages and limitations of using different methods to construct PDITOs,so as to explore their application in the treatment of bladder cancer.

High-risk non-muscle invasive bladder cancer (HR-NMIBC) is associated with a higher risk of recurrence and progression. The standard treatment involves intravesical Bacillus Calmette-Guérin (BCG) instillation following transurethral resection of the bladder cancer. However, in cases of BCG unresponsiveness, radical cystectomy is typically recommended. Due to the high complication rates and significant impact on quality of life associated with this procedure, bladder-preserving treatment (BPT) strategies have emerged as an alternative. This review summarizes recent advances in BPT, including combined chemoradiotherapy, immune checkpoint inhibitors, targeted therapies, localized precision treatments, and novel immunomodulators. With ongoing technological and therapeutic innovations, BPT has become an effective alternative for patients who are unable or unwilling to undergo surgery, reshaping the treatment landscape of HR-NMIBC.

Objective To compare the survival outcomes of bladder cancer with non-pure urothelium(BCa with n-pU)and bladder cancer with pure urothelium(BCa with pU)treated with robot-assisted radical cystectomy(RARC).Methods Clinical data of BCa patients treated with RARC in Nanjing Drum Tower Hospital during Oct.2014 and Mar.2022 were retrospectively analyzed.The patients were divided into n-pU group and pU group.After the baseline differences between groups were balanced with propensity score matching(PSM),the overall survival(OS)and recurrence-free survival(RFS)curve were plotted using Kaplan-Meier method and compared using Log-rank test.Univariate and multivariate analysis were performed with Cox model to identify the influencing factors of prognosis.Based on the results,a secondary grouping was performed to compare the survival differences between subgroups and further investigate the prognostic factors.Results After PSM,there were 53 pairs of BCa patients.There were no significant differences in the baseline data between the pU and n-pU groups(P<0.05).Regardless of T stage,there were no significant differences in OS and RFS between the two groups(P=0.217,P=0.109).Univariate Cox regression analysis showed that T stage(>T2)was a significant risk factor of OS and RFS(P<0.05).In the early pathological stage(≤T2),there were no significant differences in OS and RFS(P=0.565,P=0.344).In the advanced pathological stage(>T2),the OS and RFS of n-pU were significantly worse than those of pU patients(P=0.025,P=0.034).Conclusion The prognosis of BCa patients with n-pU who received RARC is significantly correlated with pathological status.At>T2 stage,n-pU patients have worse prognosis than pU patients in the same pathological status.

【Objective】 To develop a clinical prediction model based on 68Ga-prostate-specific membrane antigen-11 (68Ga-PSMA-11), positron emission tomography/computed tomography (PET/CT) and multiparametric magnetic resonance imaging (mpMRI) parameters to stratify prostate cancer patients undergoing targeted biopsy, so as to avoid unnecessary systematic biopsy. 【Methods】 A total of 96 clinically significant prostate cancer (csPCa) patients who underwent 68Ga-PSMA-11 PET/CT and mpMRI prior to prostate targeted biopsy with systematic biopsy during Jan.2020 and Feb.2023 in Nanjing Drum Tower Hospital were retrospectively analyzed.By univariate and multivariate logistic regression analyses, maximum standard uptake value (SUVmax) in 68Ga-PSMA-11 PET/CT and minimum apparent diffusion coefficien (ADCmin) in mpMRI, as well as clinical parameters were evaluated to identify the independent predictors correlative with the effective diagnosis of targeted biopsy, and a clinical prediction model was constructed. 【Results】 Multivariate logistic regression analysis showed that SUVmax (OR=0.878, 95%CI: 0.804-0.959, P=0.004) and ADCmin (OR=1.005, 95%CI:1.001-1.010, P=0.027) were independent predictors of the effective diagnosis of targeted biopsy alone.The sensitivity, specificity, accuracy and area under the receiver operator characteristic curve (AUC) of the model were 0.80, 0.80, 0.83 and 0.84, respectively. 【Conclusion】 The clinical prediction model based on 68Ga-PSMA-11 PET/CT and mpMRI parameters is helpful to improve the effective diagnosis of targeted biopsy alone, and has practical value to stratify patients with csPCa so as to safely avoid systematic biopsy and effectively balance the benefits and risks.

Objective:To analyze the prognostic factors of robot-assisted radical cystectomy (RARC).Methods:The clinical data of 224 patients underwent RARC from December 2014 to December 2018 in Nanjing Drum Hospital were reviewed. There were 193 males and 31 females, aged 36-92 years, with mean of 68 years. There were 7 patients(3.1%)undergoing neoadjuvant chemotherapy, the ASA scores of 125 patients (55.8%) were more than 2, and the mean body mass index was 23.4(15.4-35.5)kg/m 2. All patients were treated with RARC, with 72(32.1%) patients undergoing intraoperative blood transfusion. Kaplan-Meier method was used to analyze recurrence-free survival rate (RFS), cancer-specific survival rate (CSS) and overall survival rate (OS). Cox multivariate risk ratio model was used to evaluate the correlation between survival outcome and perioperative and pathological factors in patients treated with RARC. Results:For pathological status, there were 82 of ≤T 1, 64 of T 2, 57 of T 3 and 21 of T 4. Of all the patients, 49(21.9%) had lymph node metastasis, 12(5.4%) had positive surgical margin, 82(36.6%) had lymphovascular invasion(LVI), and 41(18.3%) underwent adjuvant chemotherapy. Follow-up time was between 11-60 months, and the median follow-up time was 24 months. The 5-year cumulative OS, RFS and CSS were 57.15%, 48.84% and 59.60%, respectively. Univariate Cox regression analysis showed that T stage( HR=5.764, 95% CI 1.926-17.249, P=0.002; HR=4.086, 95% CI 1.611-10.364, P=0.003; HR=9.391, 95% CI 2.118-41.637, P=0.003), N stage( HR=6.446, 95% CI 3.438-12.087, P<0.001; HR=5.661, 95% CI 3.086-10.385, P<0.001; HR=5.980, 95% CI 2.982-11.992, P<0.001), LVI( HR=3.319, 95% CI 2.008-5.486, P<0.001; HR=2.894, 95% CI 1.782-4.701, P<0.001; HR=3.471, 95% CI 2.017-5.974, P<0.001), American Society of Anesthesia (ASA)score( HR=2.888, 95% CI 1.619-5.150, P<0.001; HR=1.765, 95% CI 1.060-2.940, P=0.029; HR=2.612, 95% CI 1.424-4.792, P=0.002), body mass index( HR=0.886, 95% CI 0.819-0.957, P=0.002; HR=0.885, 95% CI 0.819-0.955, P=0.002; HR=0.862, 95% CI 0.792-0.938, P=0.001), age( HR=1.580, 95% CI 1.250-1.997, P<0.001; HR=1.362, 95% CI 1.088-1.705, P=0.007; HR=1.530, 95% CI 1.190-1.968, P=0.001) and intraoperative blood transfusion( HR=1.899, 95% CI 1.160-3.108, P=0.011; HR=2.218, 95% CI 1.371-3.587, P=0.001; HR=2.227, 95% CI 1.312-3.782, P=0.003) were significantly related to survival outcome. Multivariate Cox regression analysis showed that T stage( HR=4.506, 95% CI 1.433-14.175, P=0.01; HR=3.159, 95% CI 1.180-8.454, P=0.022; HR=7.810, 95% CI 1.674-36.444, P=0.009), N stage( HR=6.096, 95% CI 2.981-12.467, P<0.001; HR=5.368, 95% CI 2.683-10.740, P<0.001; HR=5.539, 95% CI 2.497-12.288, P<0.001) and ASA score( HR=6.180, 95% CI 2.371-16.110, P<0.001; HR=2.702, 95% CI 1.175-6.215, P=0.019; HR=6.471, 95% CI 2.290-18.286, P<0.001) were independent predictors of RFS, CSS and OS, and adjuvant chemotherapy( R=0.434, 95% CI 0.202-0.930, P=0.032) could only predict OS. Conclusion:T stage, N stage and ASA were main independent predictors of postoperative survival outcomes, and adjuvant chemotherapy was independent predictor of OS.
