ABSTRACT
OBJECTIVE@#To analyze the clinical pathologic characteristics of cervical intraepithelial neoplasia grade III (CINIII ) and to explore optimal surgery for CINIII patients.@*METHODS@#The clinical pathologic characteristics, surgical treatments, prognosis and history of 383 CINIII patients, who hospitalized from August 2005 to December 2010, were reviewed and analyzed. Among the patients, 213 (55.6%) received cold-knife conization surgery and 170 (44.4%) received ordinary electric knife conization surgery.@*RESULTS@#There was no significant statistic difference between cold-knife conization group and ordinary electric-knife conization group on the level of clearance of the pathologic tissues and the cervical cone diameter and cone high. Intraoperative blood loss was (13.1±5.2) mL and (25.5±17.2) mL. Bleeding of electric knife conization group, compared with that of the cold knife conization group, decreased by nearly 50%. The difference between the 2 groups was significant (P<0.01). Pathological examination after conization operation indicated that 350 out of the 383 patients didn't show pathological upgrade while 33 patients showed pathological development, among which 21 were diagnosed with invasive cervical cancer at Ia1 clincal stage, 7 atIa2 clincal stage and 5 atIb1 clincal stage. In 3 cases (14.3%) Ia1 cervical cancer patients, fertility requirements and negative margins with cervical conization were closely followed up, and one patient (4.8%) with positive margin and fertility requirements had re-conecut. The remaining 17 (80.9%) had resected the uterus outside the fascia (or plus attachments) . All the 12 patients with invasive cervical cancer at Ia2 orIb1 clinical stage received radical hysterectomy. No tumor recurrence was observed in the 383 patients.@*CONCLUSION@#Treatment optimazation of CINIII patients should be based on clinical pathological diagnosis and individual requirements. Both cervical conization surgery and total hysterectomy have been proved safe and practical for CINIII patients.
