Establishing the prediction models for recurrence and progression of T1G3 bladder urothelial carcinoma

We aim to determine clinical recurrence and progression risk factors of T1G3 bladder cancer (BCa), and to establish recurrence and progression prediction models. 5-year follow-up records of 106 T1G3 BCa patients from January 2012 to December 2016 were analyzed for recurrence and progression. Two-sample T-test, Chi-square test, Mann-Whitney test, Kaplan-Meier curves, Cox univariate and multivariate analyses were performed to determine the independent risk factors. Effective prognostic nomograms were established to provide individualized prediction, and the calibration curves were founded to evaluate the agreements of the predicted probability with the actual observed probability. Receiver operating characteristic (ROC) curves were generated for the recurrence and progression prediction models. The stability of prediction models was validated with an external cohort included 61 T1G3 BCa patients. Of the 106 T1G3 BCa patients, 77 were males (72.6%) and 29 were females (27.4%), with median age 70 years. Within 5 years, recurrence was identified in 67 cases (63.2%), and progression was identified in 31 cases (29.2%). The results showed that large size of tumor, multifocal tumors, recrudescent tumor, non-BCG perfusion therapy were the independent risk factors for recurrence, and large size of tumor, multifocal tumors, recrudescent tumor, concomitant carcinoma in situ (CIS) were the independent risk factors for progression. However, no evidence shown that tumor location or operative...

Authors: Ericson KJ, Murthy PB, Bryk DJ, Ramkumar RR, Broughman JR, Khanna A, Mian OY, Campbell SC Abstract Bladder-sparing therapies for the treatment of nonmetastatic muscle-invasive bladder cancers are included in both American and European guidelines. Numerous treatment approaches have been described, including partial cystectomy, radiation monotherapy, and radical transurethral resection. However, the most oncologically favorable and well-studied regimen employs a multimodal approach that consists of maximal transurethral resection of the bladder tumor followed by concurrent radiosensitizing chemotherapy and r...

;chel R Abstract Bacillus Calmette-Guérin instillation following removal of the tumor is the first-line of treatment for urothelial carcinoma in situ (CIS), the precursor lesion of most muscle-invasive bladder cancers. Bacillus Calmette-Guérin therapy fails in>50% of cases and second-line radical cystectomy is associated with overtreatment and drastic lifestyle consequences. Given the need for alternative bladder-preserving therapies, we identified genomic alterations (GAs) in urothelial CIS having the potential to predict response to targeted therapies. Laser-capture microdissection was applied t...

SummaryA  substantial increase in the number of elderly patients with muscle invasive bladder cancer (MIBC) is expected in upcoming years due to demographic changes and the peak incidence of bladder cancer in the 8th decade of life. The management of these patients is mainly driven by chronological age, co morbidities, tumor characteristics (unifocality, multifocality, concomitant carcinoma in situ, depth of invasion) and the presence of tumor-related symptoms (hematuria, pain, bladder dysfunction). A potential algorithm for the treatment of elderly patients with MIBC is presented. Ideally these pati ents ar...

CONCLUSIONS: The presence of detrusor muscle in TURB specimen, the absence of concomitant carcinoma in situ and the en-bloc resection were able to predict a negative histology at re-TURB, opening the door to the possibility to avoid it in an extremely well-selected cohort of patients. External validations and prospective studies are urgently needed. PMID: 31526650 [PubMed - as supplied by publisher]

ConclusionOur study showed no differences in per-patient tumour detection between WLI and NBI. Although NBI has significant benefits for detecting individual lesions overlooked by WLI-cystoscopy, this did not positively affect recurrence-free survival after transurethral resection.

Urothelial carcinoma in situ (CIS) is a high-grade noninvasive malignancy with a high tendency of progression. Although it is typically grouped with other nonmuscle invasive bladder cancers, its higher grade and aggressiveness make it a unique clinical entity. Urothelial CIS is histologically characterized by replacement of the urothelium by cells which fulfill the morphologic criteria of malignancy including nuclear pleomorphism, hyperchromasia, prominent nucleoli, and increased numbers of normal and abnormal mitoses. Urothelial CIS may be categorized as primary when it is not associated with any past or present urothelia...
