USP8 expression level is helpful in predicting disease recurrence of CSCC. Kaplan-Meier survival analyses were performed based on all pathological characteristics and USP8 protein levels, respectively. Retrieved factors included: age (A), HPV infection (B), FIGO stage (C), horizontal diffusion diameter (D), stromal invasion depth (E), vaginal invasion (F), parametrial invasion (G), lymphovascular invasion (H), pelvic lymph node metastasis (I), and USP8 protein expression (J).
