Demographic and clinical characteristics for early cervical
cancer
There were 800 women in the study population. Table 1 illustrates the
baseline characteristics of patients with early cervical cancer. The
median (IQR) age was 48 (41-55) years, and the most common histology was
squamous cell carcinoma (n=710, 88.8%).
According to the FIGO-2018 staging
criteria, we restaged these 800 women from FIGO-2009 to FIGO-2018
(Figure S1). The revised FIGO-2018
system has resulted in stage migration in many women with early-stage
cervical cancer. Stage migration occurred in 47.13% (377/800) due to
tumour size (36.5%, 292/800) or nodal metastases (10.63%, 85/800).
The most common clinical stage was
IB1 (n =231, 28.88%), followed by IB2 (n = 206, 25.75%) and IIIC (n =
158, 19.75%).
The median delay time for the whole cohort was 12 weeks; 352 (44%)
women had a delay time <12 weeks, and 448 (56%) had a delay
time ≥12 weeks. There were no significant differences between the two
groups in terms of the presence of LVSI, depth of invasion, tumour size,
parametrial invasion, etc (Table 1).
