Abstract

Patients with cervical cancer diagnosed with a para-aortic lymph node (PALN) metastasis by computed tomography (CT) scan were analyzed to identify associated prognostic factors. A total of 55 patients were reviewed, and 27 of these patients underwent extended-field radiotherapy (EFRT). The median PALN dose in patients receiving EFRT was 45 Gy (range, 27-57.6 Gy). Of the 55 patients, 28 underwent pelvic radiotherapy (RT); concurrent chemoradiotherapy (CCRT) was administered to 41 patients. The Kaplan-Meier method was used to calculate the actuarial rate. Multivariate analysis was performed using the Cox proportional hazards model. Five-year overall survival (OS) rates were 41% and 17.9% in patients undergoing EFRT and pelvic RT (P = 0.030), respectively. Age <53 years (P = 0.023), FIGO Stage I-II (P = 0.002), and treatment with EFRT (P = 0.003) were independent predictors of better OS. The use of CCRT (P = 0.014), Stage I-II (P = 0.002), and treatment using EFRT (P = 0.036) were independent predictors of distant metastasis. In patients undergoing EFRT plus CCRT, the 5-year OS was 50%. Three-year PALN disease-free rates were 8.8%, 57.9% and 100% (P <0.001) in CCRT patients who received PALN doses of 0 Gy, ≤45 Gy and ≥50.4 Gy, respectively. Although PALN metastasis is thought to be distant metastasis in cervical cancer, EFRT plus CCRT shows a good outcome, particularly in younger patients in an early FIGO stage. Cervical cancer with a PALN metastasis should not be considered incurable. Doses ≥50.4 Gy for treating PALN may result in better disease control.
