Abstract
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 method was independent risk factors for recurrence and progression. Based on the results of Cox regression analyses, the independent risk factors were used to establish the prediction nomograms to calculate the recurrence and progression probability of each T1G3 BCa patient. Calibration curves, ROC curves and external validation displayed that the nomograms had great value of prediction.

A novel treatment strategy for newly diagnosed high-grade T1 bladder cancer: Gemcitabine and cisplatin adjuvant chemotherapy-A single-institution experience. Urol Oncol 2016; 35:38.e9-38.e15. [PMID: 28040419 DOI: 10.1016/j.urolonc.2016.08.017] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2016] [Revised: 08/10/2016] [Accepted: 08/27/2016] [Indexed: 11/29/2022]
Abstract
BACKGROUND Management of high-grade T1 (formerly T1G3) bladder cancer continues to be controversial. Should patients with T1G3 bladder cancer have an immediate radical cystectomy or should they receive intravesical bacillus Calmette-Guérin-preserving bladder? Gemcitabine and cisplatin (GC) adjuvant chemotherapy may help to strike a balance between intravesical and early cystectomy. For purposes of this study, we continue to refer high-grade T1 lesion as "T1G3." OBJECTIVE To evaluate the characteristics and the long-term outcome of GC adjuvant chemotherapy in T1G3 bladder cancer after transurethral resection of bladder tumor (TURBT). MATERIALS AND METHODS We retrospectively reviewed 48 patients who were newly diagnosed with T1G3 bladder cancer between January 2009 and December 2012. A total of 48 patients received 4 cycles of GC adjuvant chemotherapy after TURBT. One month after 4 cycles of GC adjuvant chemotherapy, response was evaluated by re-TURBT. Median follow-up was 59.5 (range: 18-70) months, all patients have been observed for more than 3 years. Salvage cystectomy was recommended for patients with persistent disease and for tumor progression after initial complete response. RESULT Complete response was achieved in 44 (91.7%) patients. Of complete responders, 5 patients experienced recurrence and 5 patients showed progression. The progression rate and disease-specific survival rate were 10.4% and 91.7% at 3 years, respectively. More than 80% of survivors preserved their bladder. Kaplan-Meier curves showed that concomitant carcinoma in situ (CIS) was the only factor that had an influence on progression-free survival (P = 0.022) and disease-specific survival (P = 0.017). Concomitant CIS was the prognostic factor for progression rate and disease-specific survival rate at 3 years (P = 0.008 and P = 0.035). CONCLUSION GC adjuvant chemotherapy is a safe conservative treatment for T1G3 bladder cancer, but effective is really a phase II study. Patients with T1G3 bladder cancer with concomitant CIS should be treated more aggressively because of the high risk of progression.

Abstract
PURPOSE OF REVIEW Although the conservative approach including Bacillus Calmette-Guerin (BCG) therapy is considered as the first-line option in high-risk nonmuscle invasive bladder tumors, cystectomy is often required as an alternative treatment in the case of BCG failure. Considering all the parameters, including clinical data, endoscopic aspects and new biological markers, the question of the indication, and moreover timing, of cystectomy has become crucial. RECENT FINDINGS In fact, the real positive effect of BCG remains controversial and its actual benefit in terms of survival is not evident. Therefore, early cystectomy for this population with high risk of progression and metastasis diffusion is clearly a radical approach which can lead to a reduction in specific mortality. Recent articles have studied the parameters involved in this issue to determine the exact timing of cystectomy. SUMMARY To avoid delay of appropriate treatment, it is crucial to determine the non-BCG responder population. Unfortunately, no consensual marker is currently available. Nevertheless, multifocal tumors, associated carcinoma in situ, prostatic urethral involvement, tumoral size greater than 3 cm and depth of infiltration are useful parameters in clinical practice to propose early cystectomy. In the future, the crucial question of cystectomy timing may be answered by progress in molecular signatures for bladder cancers.

Abstract
OBJECTIVE To identify the likelihood of finding one or more positive lymph nodes (LNs) according to the number of LNs removed at radical cystectomy (RC), as the number of LNs removed affects disease progression and survival after RC. PATIENTS AND METHODS Between 1984 and 2003, 731 assessable patients had RC and bilateral pelvic lymphadenectomy at three different institutions. ROC curve coordinates were used to determine the probability of identifying one or more positive LNs according to the total number of removed LNs. RESULTS Of the 731 patients, 174 (23.8%) had LNs metastases. The mean (median, range) number of LNs removed was 18.7 (17, 1-80). The ROC coordinate-based plots of the number of removed LNs and the probability of finding one or more LNs metastases indicated that removing 45 LNs yielded a 90% probability. Conversely, removing either 15 or 25 LNs indicated, respectively, 50% and 75% probability of detecting one or more LNs metastases. CONCLUSIONS These data indicate that removing 25 LNs might represent the lowest threshold for the extent of lymphadenectomy at RC. Our findings confirm the importance of an extended lymph node dissection.
