Abstract
INTRODUCTION AND OBJECTIVE Bladder preservation with trimodal therapy (TMT) has emerged as a feasible alternative strategy to treat localized muscle invasive bladder cancer (MIBC). There is lack of consensus regarding the treatment of local recurrence following TMT. The aim of this paper is to determine whether traditional NMIBC therapies can be applied to the management of NMIBC recurrences following TMT. METHODS Using our institutional bladder cancer radiotherapy database, all patients with recurrent NMIBC following TMT were identified between 2008-2019. TMT patients were initially treated with maximal TURBT followed by combination chemotherapy/radiotherapy (weekly cisplatin 40 mg/m2 and 64-66 Gy to the bladder) with localizing Lipiodol injections. We compared NMIBC recurrent patients to a cohort of matched controls with primary NMIBC, hypothesizing that post-TMT patients treated with traditional NMIBC therapies would have outcomes similar to patients with primary NMIBC. Primary NMIBC patients were derived from our local NMIBC database and matching was based on clinical stage and grade in a 5:1 manner (controls:cases). Recurrences in the TMT group were managed according to the standard therapy for NMIBC. A descriptive analysis was performed between patients undergoing TMT with NMIBC recurrence and patients initially diagnosed with de novo NMIBC. Overall survival was calculated for each group and analyzed using the Kaplan-Meier method and Cox proportional hazards modeling. Recurrence-free and cystectomy-free survival were analyzed using competing risk methods. RESULTS Twelve patients out of 124 patients in the TMT cohort had NMIBC recurrence and were compared to 60 patients in a control group who were diagnosed with de-novo NMIBC. Median age of the TMT group was 78 [54 - 84] years versus 66 [23 - 88] years for the non-TMT group. Median follow-up for was 3.6 years versus 5.4 years in the non-TMT group. The clinical stage of the TMT NMIBC recurrences was Ta (n = 4), T1 (n = 3), CIS (n = 5). During the follow-up period, 38 (63%) further recurrences occurred in the non-TMT group compared to 2 (17%) in TMT group (P = 0.004). One patient (8%) from the TMT group required a cystectomy compared to 11 (18%) in the non-TMT group (P = 0.68). There were 2 non-cancer deaths (17%) in TMT group compared to one (2%) in the non-TMT group. CONCLUSION Our study demonstrates NMIBC recurrences post TMT can be successfully managed with endoscopic and adjuvant intravesical therapies.

Non coding RNAs as the critical factors in chemo resistance of bladder tumor cells. Diagn Pathol 2020; 15:136. [PMID: 33183321 PMCID: PMC7659041 DOI: 10.1186/s13000-020-01054-3] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2020] [Accepted: 11/05/2020] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND Bladder cancer (BCa) is the ninth frequent and 13th leading cause of cancer related deaths in the world which is mainly observed among men. There is a declining mortality rates in developed countries. Although, the majority of BCa patients present Non-Muscle-Invasive Bladder Cancer (NMIBC) tumors, only 30% of patients suffer from muscle invasion and distant metastases. Radical cystoprostatectomy, radiation, and chemotherapy have proven to be efficient in metastatic tumors. However, tumor relapse is observed in a noticeable ratio of patients following the chemotherapeutic treatment. Non-coding RNAs (ncRNAs) are important factors during tumor progression and chemo resistance which can be used as diagnostic and prognostic biomarkers of BCa. MAIN BODY In present review we summarized all of the lncRNAs and miRNAs associated with chemotherapeutic resistance in bladder tumor cells. CONCLUSIONS This review paves the way of introducing a prognostic panel of ncRNAs for the BCa patients which can be useful to select a proper drug based on the lncRNA profiles of patients to reduce the cytotoxic effects of chemotherapy in such patients.

Abstract
The objective of the study was to investigate the predictive value of various clinical, biochemical, and histopathological parameters, with special emphasis on the expression of the retinoblastoma protein (pRB), on the radiation response in bladder cancer. In order to obtain a truly objective response measure, patients receiving preoperative radiotherapy followed by cystectomy were studied. Pretreatment tumour samples and clinical data from 108 consecutive patients were collected. End points were complete response (CR) to radiotherapy, relapse-free survival time and overall survival time. Expression of pRB was assessed by immunohistochemical staining as present or absent. Complete response to radiotherapy was obtained in 42 of 106 evaluable patients (40%). Predictive for CR to radiotherapy, in univariate analysis, was transurethral resection (as opposed to biopsy), B-haemoglobin, no upper urinary retention, and loss of pRB staining. Loss of pRB staining was the strongest independent predictor of radiation response in multivariate logistic regression analysis and absence of upper urinary retention was the only other significant factor. Loss of pRB was the only parameter showing statistically significant, independent association with relapse-free survival, whereas B-haemoglobin was also independently associated with overall survival. Loss of pRB expression seems to indicate a phenotype displaying enhanced radiosensivity and may be of benefit by denoting patients who would selectively benefit from a treatment schedule containing radiotherapy.
