A Cohort Study for the Following up of Conization
A Cohort Study for the Following up of Conization
This study is to investigate the oncologic and obstetric outcomes in patients with conization
 for uterine cervical lesions from January 1, 2000 to January 1, 2019 in Peking Union Medical
 College Hospital.

 The primary objectives consist of following:

 1. The cumulative incidences of precancerous lesions and cancers of lower genital tract in
 patients who accepted conization for high grade intraepithelial neoplasia (HSIL),
 carcinoma in situ and stage IA1 cancer (FIGO 2009)

 2. The cumulative pregnancy rates in patients sparing the fertility

 The secondary objectives consist of following:

 1. The effects of surgical protocols (modified Sturmdorf method and "8" figure suture) and
 energy equipment (cold knife and monopolar electrical cautery) on the oncologic and
 obstetric outcomes, and on the histological components.

 2. A full description of histological components of the conization specimens

 3. The cytological and virus outcomes after conization, based on the thin prep liquid-based
 cytology test (TCT) and high-risk human papillomavirus (HPV) testing
Inclusion Criteria:

 -  Accepting conization in the study center

 -  Aged 18 years or older

 Exclusion Criteria:

 -  Not meeting any of the inclusion criteria
