Aim This study aimed to identify the postoperative histological features affecting the prognosis of patients with early‐stage cervical cancer who underwent open radical hysterectomy. Methods This retrospective study enrolled 374 patients with pT1a, 1b1 and 2a1 early‐stage cervical cancer who underwent open radical hysterectomy between 2001 and 2018. Survival outcomes were analyzed by Kaplan–Meier method and compared with log‐rank test. Using the Cox proportional hazards regression test, we conducted a multivariate analysis for disease‐free survival and overall survival. Results Others histology, including other epithelial tumors and neuroendocrine tumors, had a significantly worse prognosis in both disease‐free survival and overall survival than those of squamous cell carcinoma and adenocarcinoma (hazard ratio, 4.37 and 11.76; P = 0.006 and P = 0.002, respectively), along with lymph node metastasis (hazard ratio, 2.99 and 7.03; P = 0.009 and P = 0.001, respectively). Conclusion Others histology including adenosquamous carcinoma had a poor prognosis in early‐stage cervical cancer as with high‐risk factors.
