It is usually treated with excisional surgery. This study aimed to find the factors affecting the cure rate of cervical intraepithelial neoplasia recurrence after surgery using defective models. Study design: A retrospective cohort study. Methods: Excisional surgery was performed on 307 patients with high-grade cervical intraepithelial neoplasia, from 2009 to 2017. The patients were followed up until recurrence based on histopathology report. Hematologic factors were measured before surgery. The cure rates were estimated using defective models with a Gamma frailty term and the results were compared. Results: Neutrophil-to-lymphocyte ratio (NLR) (P&lt;0.001) and excised mass size (P&lt;0.001) had significant impacts on cure rates, and their cut-off values were 1.9 (P&lt;0.001) and 15 mm2 (P&lt;0.001), respectively. Patients with lower neutrophil-to-lymphocyte ratios and larger excised tissues had higher cure rates. Defective 3-parameter Gompertz distribution with gamma frailty term had the best fit to the data, and its estimated cure rates were 98% among patients with an excised mass size of &gt;15 mm2 and NLR of &lt;1.9, 84% among patients with an excised mass size of &gt;15 mm2 and NLR of &gt;1.9, 79% among patients with an excised mass size of &lt;15 mm2 and NLR of &lt;1.9, and 30% among patients with an excised mass size of &lt;15 mm2 and NLR of &gt;1.9. Conclusion: Cervical intraepithelial neoplasia must be identified and treated before its progress. Excision of more tissues during excisional surgery, especially when the NLR of the patient is high, can help to prevent cervical intraepithelial neoplasia recurrence.<\/jats:p>","DOI":"10.34172\/jrhs.2021.56","type":"journal-article","created":{"date-parts":[[2021,10,26]],"date-time":"2021-10-26T10:44:33Z","timestamp":1635245073000},"page":"e00524-e00524","update-policy":"https:\/\/doi.org\/10.34172\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Evaluation of the Factors Affecting the Cure Rate of Cervical Intra-Epithelial Neoplasia Recurrence Using Defective Models"],"prefix":"10.34172","volume":"21","author":[{"given":"Nastaran","family":"Hajizadeh","sequence":"first","affiliation":[{"name":"Department of Biostatistics, Faculty of Paramedical Sciences, Shahid Beheshti University of Medical Sciences, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahmad Reza","family":"Baghestani","sequence":"additional","affiliation":[{"name":"Physiotherapy Research Center, Department of Biostatistics, Faculty of Paramedical Sciences, Shahid Beheshti University of Medical Sciences, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohamad Amin","family":"Pourhoseingholi","sequence":"additional","affiliation":[{"name":"Gastroenterology and Liver Diseases Research Center, Research Institute for Gastroenterology and Liver Diseases, Shahid Beheshti University of Medical Sciences, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ali Akbar","family":"Khadem Maboudi","sequence":"additional","affiliation":[{"name":"Department of Biostatistics, Faculty of Paramedical Sciences, Shahid Beheshti University of Medical Sciences, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Farah","family":"Farzaneh","sequence":"additional","affiliation":[{"name":"Preventive Gynaecology Research Center, Taleghani Hospital, Shahid Beheshti University of Medical Sciences, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nafiseh","family":"Faghih","sequence":"additional","affiliation":[{"name":"Preventive Gynaecology Research Center, Taleghani Hospital, Shahid Beheshti University of Medical Sciences, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"20123","published-online":{"date-parts":[[2021,7,12]]},"reference":[{"key":"R1","doi-asserted-by":"crossref","first-page":"394","DOI":"10.3322\/caac.21492","article-title":"Global cancer statistics 2018: GLOBOCAN estimates of incidence and mortality worldwide for 36 cancers in 185 countries","volume":"68","author":"Bray F","year":"2018","journal-title":"CA Cancer J Clin"},{"key":"R2","unstructured":"Garcia F, Hatch KD, Berek JS.
