Strengths and Limitations
We first demonstrated that SLNB with CNS had appropriate diagnostic validity in a prospective, single-centre study with a large sample size of 356 patients. The findings suggest that SLNB with CNS is a simple and effective procedure in early-stage cervical cancer, especially for patients with tumours smaller than 20 mm.
Our study has several limitations. SLNB with CNS for the treatment of cervical cancer is still new; thus, multicentre studies should be performed to further confirm our results. We did not apply ideal ultrastaging for all sentinel lymph nodes because of requirements for the preservation of pathological tissue.
