Abstract
Background
To investigate the survival outcomes of stage IB1 cervical cancer patients with tumor size ≤ 2 cm who underwent laparoscopic or abdominal radical hysterectomy.
Methods
We retrospectively analyzed stage IB1 cervical cancer patients with a tumor size ≤ 2 cm who underwent laparoscopic or abdominal radical hysterectomy in China between 2004 and 2016. A real-world study (RWS) and 1:1 matching was used in the study.
Results
After 1:1 matching, laparoscopic (n = 926) and abdominal radical hysterectomy (n = 926) had similar 5-year overall survival and disease-free survival rates in stage IB1 cervical cancer with a tumor size ≤ 2 cm. Subsequently, in cervical squamous carcinoma with tumor size ≤ 2 cm, the laparoscopic and abdominal groups (724 cases, respectively) showed comparable 5-year overall survival and disease-free survival rates. Finally, in cervical adenocarcinoma or adenosquamous carcinoma with tumor size ≤ 2 cm, the laparoscopic group (n = 174) had a similar 5-year overall survival rate but a lower disease-free survival rate compared to those of the abdominal group (disease-free survival: 89.9% vs. 98.0%, respectively, P = 0.006; hazard ratio (HR), 5.094; 95% confidence interval (CI), 1.400–18.535; P = 0.013; n = 174). The RWS results were similar to the 1:1 matching results.
Conclusions
Patients with squamous cell carcinoma in stage IB1 cervical cancer with tumor size ≤ 2 cm might be suitable for laparoscopic surgery, while patients with adenocarcinoma or adenosquamous carcinoma with tumor size ≤ 2 cm are not candidates for laparoscopic surgery.
