ABSTRACT
<p><b>OBJECTIVE</b>To explore the low-risk indicators of early cervical cancer.</p><p><b>METHODS</b>The medical records of 201 patients undergoing radical surgery between March 2000 and April 2011 for staging Ia2,Ib1 (tumor diameter≤2cm) cervix cancer were retrospectively reviewed, with particular focus on the pathological findings [parametrial involvement, positive margin, positive pelvic lymph node, and lymph vascular space invasion (LVSI)], treatment, and outcomes.</p><p><b>RESULTS</b>The operation duration ranged 75-330min (mean188.87 min) and the intra-operative blood loss was approximately 100-2500 ml (mean 583.33 ml). Pathology showed the rate of parametrial spread, positive margins, lymph node metastasis, LVSI was 0, 6.97%, 12.44%, and 17.41%. Based on the pathologic findings, the patients were classified as two groups group A had 147 patients(73.13%) with no neoplasm or tumor diameter ≤2 cm,while group B had 54 patients (26.87%) with tumor diameter > 2 cm. The incidence of ≥ 1/2 cervical stromal invasion, LVSI, positive lymph node, underlying section of uterus involvement, and low tumor differentiation in group A and B were 20.14% vs. 85.19% (p = 0.000), 13.61% vs. 27.78%(p = 0.019), 9.52% vs. 20.37% (p=0.039), 4.82% vs. 14.81% (p=0.008), and 35.37% vs. 44.44% (p=0.025), respectively, with significant differences. Among the 163 patients who were followed up for more than 3 months, 10(6.13%) developed recurrence whereas no patient died.</p><p><b>CONCLUSIONS</b>Pathologic parametrial involvement in clinical stage 1a2 and 1b1 cervical cancer is uncommon. Tumor size and cervical stromal invasion can be used to identify low-risk population that are worthy of consideration for studies of less radical surgery performed in conjunction with pelvic lymphadenectomy.</p>
