Main Finding
In our study, the median OS duration was 32.5 months, similar to the median OS of 30 months reported by Zhang et al.[8]. The OS was much shorter than that of common cervical cancer,[10] which can be attributed to its special histological type. We found that mixed pathology was a positive prognostic factor for patients with NECC (HR,0.02; 95% CI, 0.00~0.45, P =0.014). Meanwhile, it also showed that only uterus invasion was a poor prognostic factor related to the OS.
