Is the pathologic tumor size associated with survival in early cervical cancer treated with radical hysterectomy and adjuvant radiotherapy?

Objective: In 2018 International Federation of Gynecology and Obstetrics (FIGO) staging system of uterine cervix cancer, size criteria of primary tumor has been revised. This study aimed to evaluate the validity of this new size criteria (<2, 2-4, and S4 cm) in patients who underwent radical hysterectomy and adjuvant radiation therapy (RT) for early cervical cancer. Materials and methods: We retrospectively examined 312 patients who underwent radical hysterectomy and adjuvant RT for early cervical cancer (IB-IIA) from 2001 to 2014. The effects of clinical and patho-logical factors on disease-free survival (DFS) and overall survival (OS) were evaluated in univariate and multivariate analyses. Results: After a median follow-up of 71.5 months, the 5-year DFS and OS rates were 89.5% and 94.7%, respectively. The primary tumor size was nota significant factor for DFS (p = 0.382) or OS (p = 0.725) in all patients. Conclusion: Primary tumor size was not a significant factor for survival in patients who received hys-terectomy and adjuvant RT for early cervical cancer. Adequacy of new tumor size criteria (<2, 2-4, and S4 cm) in new 2018 FIGO stage needs to be validated in further studies. (c) 2022 Taiwan Association of Obstetrics & Gynecology.
