To evaluate the potential relationship between outcomes in cervical cancer patients based on distance from our Comprehensive Cancer Center (CCC).
A retrospective cohort study of cervical cancer patients was performed. Abstracted data included: demographics, clinicopathologic variables, treatment, and survival. Analyses both by quartiles and distance <100 and ≥100miles from our institution were performed. Data were analyzed using SAS version 9.2.
390 patients living a median distance of 58.1miles (range 1.2-571miles) from our CCC were identified. Patients were generally white (n=249), non-smokers (n=226), with Stage IB disease (n=222), squamous histology (n=295) and underwent primary surgical therapy (n=229). Patients were divided into both quartiles as well as two strata: <100 and ≥100miles for comparison. Progression-free survival (PFS) and overall survival (OS) favored patients living closer to our center with a lower median OS for patients living ≥100miles (65.4vs. 99.4months; p=0.040). Cox proportional hazard modeling noted that advanced stage was predictive of inferior PFS and OS, while other clinical covariates including age, BMI, race, smoking status and histology had a variable impact on outcomes and distance >100miles was associated with a higher risk of death (hazard ratio [HR]=1.68, 95% confidence interval [CI] 1.11-2.54).
Overall survival for patients living >100miles from our CCC was worse when compared to patients in closer proximity. Outreach efforts and utilization of navigators may help decrease the impact of geographic and racial disparities on outcomes.
基于距离我们综合癌症中心(CCC)的远近,评估宫颈癌患者的预后之间的潜在关系。
对宫颈癌患者进行了一项回顾性队列研究。提取的数据包括:人口统计学、临床病理变量、治疗和生存情况。按四分位数以及距我们机构<100英里和≥100英里的距离进行了分析。使用SAS 9.2版对数据进行分析。
确定了390例居住在距我们的CCC中位距离为58.1英里(范围1.2 - 571英里)的患者。患者大多为白人(n = 249)、非吸烟者(n = 226),患有IB期疾病(n = 222),组织学类型为鳞状(n = 295),并接受了初次手术治疗(n = 229)。患者被分为四分位数以及两个层次:<100英里和≥100英里用于比较。无进展生存期(PFS)和总生存期(OS)显示,居住距离我们中心较近的患者更具优势,居住≥100英里的患者中位OS较低(65.4对99.4个月;p = 0.040)。Cox比例风险模型指出,晚期是PFS和OS较差的预测因素,而其他临床协变量包括年龄、体重指数、种族、吸烟状况和组织学对预后有不同影响,距离>100英里与较高的死亡风险相关(风险比[HR]=1.68,95%置信区间[CI] 1.11 - 2.54)。
与距离较近的患者相比,居住在距我们的CCC超过100英里的患者总生存期更差。开展外展工作和利用导航员可能有助于减少地理和种族差异对预后的影响。
