Factors predicting parametrial invasion in patients with early-stage cervical carcinomas.

The group with stage IB1 tumors >2 cm had statistically deeper cervical stromal invasion (9.99±5.04 mm, p<0.001, Kruskal-Wallis test), higher incidences of LVSI (45.3%, p = 0.002, chi-square test), and greater lymph node metastasis (24.2%, p = 0.002, chi-square test) compared to the other 2 groups (stage IA2 and stage IB tumors ≤2 cm).The group with stage IB1 tumors >2 cm showed a trend toward a higher incidence of parametrial invasion (9.5%, p = 0.14, chi-square test) compared with the other two groups (stage IA2 tumor, 0%;stage IB1 tumor ≤2 cm, 4%), though it did not reach statistical significance.
