Objective:
We aimed to compare the 5-year oncological outcomes of laparoscopic/abdominal radical hysterectomy (LRH/ARH) in patients with cervical adenosquamous carcinoma at stage IA2 to IIA2 based on the 2009 or 2018 International Federation of Gynecology and Obstetrics (FIGO) staging criteria.
Methods:
Based on the clinical diagnosis and treatment of cervical cancer in China (Four C) database, Cox risk regression models were applied to analyze tumor prognosis treated with ARH/LRH in FIGO 2009 and 2018 IA2-IIA2 patients and stratified findings according to tumor diameter (≤4 and >4 cm subgroups). And to avoid bias, propensity score matching (PSM) was also used for the cohort study.
Results:
Based on FIGO 2009 staging criteria (n = 474), there was no significant difference between the ARH and LRH groups in 5-year disease-free survival (DFS) or overall survival (OS). Lymph node metastasis was a risk factor for 5-year DFS in this stage. After PSM, lymphovascular space invasion (LVSI) was an independent risk factor for 5-year OS in the tumors ≤4 cm subgroup. Based on FIGO2018 staging criteria (n = 322), cervical interstitial infiltration depth was an independent risk factor for 5-year OS in the total population and the tumor diameter ≤4 cm subgroup.
Conclusions:
Laparoscopic surgery was not a risk factor affecting the oncologic prognosis of adenosquamous carcinoma of the cervix based on either FIGO 2009 or 2018 staging of stage IA2-IIA2. In addition, LRH may be considered for patients with early-stage cervical adenosquamous carcinoma.
