Some groups hypothesize that a delay in cystectomy may result in higher pathological stage and possibly alter survival in patients with bladder cancer. The timing of this delay has been somewhat arbitrary. We evaluated the timing from T2 bladder cancer diagnosis to cystectomy, its impact on survival and potential causes of delay.
A contemporary cohort of 214 consecutive patients presented with clinical T2 bladder cancer and underwent radical cystectomy as primary therapy. Clinicopathological parameters were maintained in an institutional database. A review of time to cystectomy, pathological stage, disease specific survival and OS was performed. Variables were tested in univariate and multivariate analyses. The log rank test was used for exploratory analyses to determine meaningful delay cutoff points.
Mean followup and time to cystectomy in the entire cohort was 40 months and 60 days, respectively. A significant disease specific survival and OS advantage was observed in patients undergoing cystectomy by 93 days or less (3.1 months) compared to greater than 93 days (p = 0.05 and 0.02, respectively). Pathological staging was similar between the groups (p = 0.15). A multivariate benefit in OS was observed in patients treated with timely cystectomy. The most common factor contributing to cystectomy delay was scheduling delay, as seen in 46% of cases.
A cystectomy delay of 3.1 months undermines patient survival, likely through the development of micrometastases, since local stage progression is not apparent at this point. Most delays are avoidable and should be minimized. Despite the need for second opinions and the impact of busy surgical schedules clinicians must strive to schedule patients efficiently and complete surgical treatment within this time frame.
一些研究小组推测,膀胱癌患者膀胱切除术延迟可能导致更高的病理分期,并可能改变生存率。这种延迟的时间选择在一定程度上具有随意性。我们评估了从T2期膀胱癌诊断到膀胱切除术的时间、其对生存率的影响以及延迟的潜在原因。
对214例连续出现临床T2期膀胱癌并接受根治性膀胱切除术作为主要治疗的患者进行当代队列研究。临床病理参数保存在机构数据库中。回顾了膀胱切除术时间、病理分期、疾病特异性生存率和总生存率。对变量进行单因素和多因素分析。采用对数秩检验进行探索性分析,以确定有意义的延迟截止点。
整个队列的平均随访时间和膀胱切除术时间分别为40个月和60天。与超过93天相比,在93天或更短时间(3.1个月)内接受膀胱切除术的患者观察到显著的疾病特异性生存率和总生存率优势(分别为p = 0.05和0.02)。两组间病理分期相似(p = 0.15)。及时进行膀胱切除术的患者在总生存率方面有多因素优势。导致膀胱切除术延迟的最常见因素是安排延迟,46%的病例中可见。
3.1个月的膀胱切除术延迟会损害患者生存,可能是通过微转移的发展,因为此时局部分期进展并不明显。大多数延迟是可以避免的,应尽量减少。尽管需要二次会诊以及繁忙的手术安排会产生影响,但临床医生必须努力高效安排患者,并在这个时间框架内完成手术治疗。
