Aim This retrospective study sought to identify the selection criteria required for a non‐radical hysterectomy with minimal parametrectomy in patients with International Federation of Gynecology and Obstetrics (FIGO) stage IB invasive cervical cancer. Methods Overall, 461 patients with FIGO stage IB cervical cancer who underwent a radical hysterectomy were reviewed clinicopathologically according to pathological tumor size (≤2 cm, >2 – ≤4 cm, and > 4 cm). Results The pathological parametrial involvement rate in the less than equal to 2 cm group (2%) was significantly lower than in greater than 2–less than equal to 4 cm (13%) or greater than 4 cm (29%) groups (both P < 0.001). The 5‐year overall survival rate was significantly higher in the less than equal to 2 cm group (97%, 95% confidence interval [CI] 94–99%) compared with greater than 2–less than equal to 4 cm (90%, 95% CI 94–86%) and greater than 4 cm (70%, 95% CI 79–60%) groups (both P < 0.001). Cox model analysis identified tumor size to be an independent prognostic factor for survival (95% CI 1.33–5.78) and recurrence (95% CI 1.31–5.66) compared to other pathological factors. However, a significant difference between the three groups was not found in rates of Grade 3 or 4 adverse events following radical hysterectomy ( P = 0.19). Conclusions Tumor size is an independent prognostic factor for survival in patients with FIGO stage IB invasive cervical cancer. This retrospective study suggests that FIGO stage IB patients with a less than equal to 2 cm tumor size are optimal candidates for non‐radical hysterectomy with minimal parametrectomy, and without resulting bladder dysfunction.
