The objective of this study is to evaluate angiogenesis in cervical intraepithelial neoplasia (CIN), microinvasive squamous cell carcinoma (MIC), and early-staged squamous cell carcinoma (SCC), stage IB–IIA of the cervix. Microvessel density (MVD) was evaluated and correlated with other pathologic prognostic factors and disease outcomes. Four hundred seventy-four cervical specimens were studied. Among these, 100 were designated normal cervix, 30 CIN1, 32 CIN2, 178 CIN3, 74 MIC, and 60 early-staged SCC. MVD per high-power field (×400) of early-staged SCC, MIC, and CIN3 were significantly higher in comparison to CIN2, CIN1, and control subjects (P<0.05). There was no statistically significant difference in MVD between control group, CIN1, and CIN2. In early-staged SCC, no correlation between MVD and pelvic lymph node status, parametrial involvement, depth of stromal invasion, and lymphovascular space invasion was found. Patients with bad outcomes (recurrence or death) showed no statistically different MVD from the ones who had unremarkable clinical courses.
