None of the factors remained independent prognostic factors for LRR in cervical cancer after multivariate Cox regression, done by stepwise backward elimination according to Wald criteria. Redundant factors were positive of close PRMs and histology for LRR; direct extension of parametrium and chemotherapy for DM; and direct extension of parametrium, lymphovascular invasion, and chemotherapy for OS.

LRR, locoregional risk; DM, distant metastasis; OS, overall survival; RR, relative risk; CI, confidence interval; PRM, parametrial resection margin; LN, lymph node; SqCC, squamous cell carcinoma.

^a)All patients with positive or close PRMs had direct extensions of parametrium (pIIB).
