The aim of this study was to evaluate the impact of surgical waiting time on clinical outcome in early stage cervical cancer.
The cohort consisted of 441 patients diagnosed with stages IA2-IB1cervical cancer who underwent radical hysterectomy and pelvic node dissection. The patients were divided into two groups based on surgical waiting time. The associations between waiting time and other potential prognostic factors with clinical outcome were evaluated.
The median surgical waiting time was 43 days. Deep stromal invasion (hazard ratio [HR], 2.5; 95% confidence interval [CI], 1.4 to 4.6; p=0.003) and lymph node metastasis (HR, 2.9; 95% CI, 1.3 to 6.7; p=0.026) were identified as independent prognostic factors for recurrence-free survival while no prognostic significance of surgical waiting time was found (p=0.677). On multivariate analysis of overall survival (OS), only deep stromal invasion (HR, 2.6; 95% CI, 1.3 to 5.0; p=0.009) and lymph node metastasis (HR, 3.6; 95% CI, 1.5 to 8.6; p=0.009) were identified as independent prognostic factors for OS. Although OS showed no significant difference between short (≤ 8 weeks) and long (>8 weeks) waiting times, multivariate analysis of OS with time-varying effects revealed that a waiting time longer than 8 weeks was associated with poorer long-term survival (after 5 years; HR, 3.4; 95% CI, 1.3 to 9.2; p=0.021).
A longer surgical waiting time was associated with diminished long-term OS of early stage cervical cancer patients.
本研究旨在评估手术等待时间对早期宫颈癌临床结局的影响。
该队列由441例被诊断为IA2 - IB1期宫颈癌并接受根治性子宫切除术和盆腔淋巴结清扫术的患者组成。根据手术等待时间将患者分为两组。评估等待时间及其他潜在预后因素与临床结局之间的关联。
手术等待时间的中位数为43天。深层间质浸润(风险比[HR],2.5;95%置信区间[CI],1.4至4.6;p = 0.003)和淋巴结转移(HR,2.9;95% CI,1.3至6.7;p = 0.026)被确定为无复发生存的独立预后因素,而未发现手术等待时间具有预后意义(p = 0.677)。在总生存(OS)的多因素分析中,仅深层间质浸润(HR,2.6;95% CI,1.3至5.0;p = 0.009)和淋巴结转移(HR,3.6;95% CI,1.5至8.6;p = 0.009)被确定为OS的独立预后因素。尽管短(≤8周)等待时间和长(>8周)等待时间的OS无显著差异,但对OS进行具有时间变化效应的多因素分析显示,等待时间超过8周与较差的长期生存相关(5年后;HR,3.4;95% CI,1.3至9.2;p = 0.021)。
较长的手术等待时间与早期宫颈癌患者长期OS降低相关。
