To investigate the curative effect and standardization of the treatment method to cervical intraepithelial neoplasia (CIN) by radiofrequency heat-coagulation minimally invasive treatment (RHMIT).

One hundred and thirteen patients with CIN in different degree (fifty two patients with CIN I, forty seven ones with CIN Ⅱ and fourteen ones with CIN Ⅲ), who were all confirmed by thinprep cytology test (TCT), electric colposcopy and cervical biopsy pathology, were treated by RHMIT method in order to maintain cervical integrity. All patients were strictly followed up from six months to 47 months, 32 months in average.

All patients with CIN in different degree in this group were fully recovered within 4 〜7 weeks after the RHMIT and supplementary treatment. During this following up stage, five hundreds and eighty-six times of TCT and two hundreds fifty six times of cervical biopsy pathology under electric colposcopy were all not found cellular atypicality.

RHMIT is a simple, safe, fast, effective and repeatable method to CIN in different degree. The indications of RHMIT to CIN are definite diagnosis, standardizing plan according to individuality and strict following-up programme.
