This stage shift may reduce the likelihood of surgical lymph node staging. It is therefore crucial to estimate the risk and risk factors of lymph node metastasis (pN+) in this group.</div></div><div><h3>Methods</h3><div>Women diagnosed with cervical cancer between 2005 and 2022 were identified from nationwide population-based registries from the Netherlands, Denmark, and Sweden. Inclusion criteria were squamous cell carcinoma or adenocarcinoma, FIGO 2009 stage IB1, a depth of invasion ≤ 5 mm and horizontal spread of > 7–≤ 40 mm.

Lymphovascular space invasion (LVSI) was a significant risk factor of pN+ (odds ratio 4.26, 95 % confidence interval 2.24–8.32). Accordingly, the risk of pN+ was ≥ 7.3 % in LVSI-positive tumours.
