Survival Outcomes of Patients With Stage IB3 Cervical Cancer Who Undergo Abdominal Radical Hysterectomy Versus Radiochemotherapy
Abstract
ObjectiveThis study aimed to compare the survival outcomes among stage IB3 cervical cancer patients who undergo abdominal radical hysterectomy (ARH)+pelvic lymphadenectomy ± para-aortic lymph node dissection versus radiochemotherapy (R-CT).MethodsBased on the large number of diagnoses and treatments for cervical cancer in the Chinese database, propensity score matching (PSM) was used to compare the 5-year overall survival (OS) and disease-free survival (DFS) rates of the ARH group and R-CT group.ResultsThere were 590 patients with stage IB3 cervical cancer according to the FIGO 2018 staging system, with 470 patients in the ARH group and 120 patients in the R-CT group. The ARH and R-CT groups showed different 5-year OS and DFS rates in the total study population, and the 5-year OS and DFS rates in the R-CT group (n = 120) were lower than those in the ARH group (n = 470) (OS: 78.1% vs. 92.1%, p < 0.001; DFS: 71.6% vs. 90.3%, p < 0.001). R-CT was associated with a worse 5-year OS rate (hazard ratio [HR] = 3.401; 95% confidence interval [CI] = 1.875–6.167; p < 0.001) and DFS rate (HR = 3.440; 95% CI = 2.075–5.703; p < 0.001) by Cox multivariate analysis. After 1:3 PSM, the 5-year OS and DFS rates in the R-CT group (n = 108) were lower than those in the RH group (n = 280) (OS: 76.4% vs. 94.0%, p < 0.001; DFS: 69.3% vs. 92.6%, p < 0.001, respectively). R-CT was associated with a worse 5-year OS rate (HR = 4.071; 95% CI = 2.042–8.117; p < 0.001) and DFS rate (HR = 4.450; 95% CI = 2.441–8.113; p < 0.001) by Cox multivariate analysis.ConclusionOur study found that for FIGO 2018 stage IB3 cervical cancer patients, ARH resulted in better OS and DFS than R-CT.
