10 mm, lymph-vascular space involvement, tumor diameter > 17.5 mm, and parametrial involvement. Postoperative treatment was significantly more frequent in patients with "abundant" vascularization (OR: 20.8, 95% CIs: 2 to 211). The presence of scanty-moderate vascularization with a PI < 0.82 or abundant vascularization with either PI > 0.82 or PI < 0.82 was associated with high-risk group in 94.4% of the cases (OR: 21.2, 95% CI: 1.9 to 236.0) Conclusion The results are consistent with a relationship between tumor angiogenesis and prognostic factors for recurrence in early cervical cancer. "Abundant" vascularization and PI < 0.82 may be related to postoperative treatment due to risk factors."/>
