Comparison of clinicopathological characteristics of endogenous and exogenous cervical cancer with its clinical significance. International Journal of Scientific Reports. 2020 Mar; 6(3): 83-892454-24562454-2164http://imsear.searo.who.int/handle/123456789/214006Background:Cervical cancer is the third leading cause of cancer death in women of less developed countries due to poor screening and decreased diagnostic approaches. We aimed to investigate and differentiate the distinct clinicopathological characteristics and prevalence of endogenous and exogenous cervical in hospitalized patients. Methods:A study was performed contained 663 patients that were enrolled and underwent for screening of endogenous and exogenous cervical cancer in Qilu Hospital of Shandong University, from January 2010 to March 2015.Results:Our results indicated that combined examination of thin-prep liquid-based cytology test and human papillomavirus(HPV)-DNA are effective for diagnosis of endogenous and exogenous cervical cancer. The clinicopathological characteristics based on tumor growth pattern, and highrisk HPV-DNA incidence had no significant difference (p>0.05) in endogenous and exogenous cervicalcancer patients. The higher ratio of lymph node metastasis in endogenous cervical cancer and exogenous cervical cancer during IB1-stage (24.3% vs 12.9%), and in IIA2-stage (36.4% vs 25%) was observed respectively. In addition, our data provide compelling evidence that the level of deep interstitial infiltration, and lymphatic vascular infiltration in endogenous cervical cancer was collectively higher (82.7% and 33%) compared to exogenous cervical cancer (62.4% and18.3%) respectively during all stages.Conclusions:The higher percentage of lymph node metastasis,deep interstitial infiltration, and lymphatic vascular infiltration was observed in endogenous cervical cancer which might be the biomarker and differential key points for the diagnosis of endogenous cervical cancer. Taken together, our study provides clinicopathological features to diagnose, and differentiate the endogenous and exogenous type cervical cancer with its prevalence.Cervical cancerEndogenous cervical cancerExogenous cervical cancerLymph node metastasisJournal ArticleIndiaDepartment of Obstetrics and Gynecology, Qilu Hospital of Shandong University, Jinan, Shandong, ChinaCenter for Reproductive Medicine, Shandong University,Shandong, ChinaNational Research Center for Assisted Reproductive Technology and Reproductive Genetics, ChinaDepartment of Obstetrics and Gynecology, Qilu Hospital of Shandong University, Jinan, Shandong, ChinaDepartment of Obstetrics and Gynecology, Qilu Hospital of Shandong University, Jinan, Shandong, ChinaDepartment of Obstetrics and Gynecology, Qilu Hospital of Shandong University, Jinan, Shandong, ChinaDepartment of Obstetrics and Gynecology, Qilu Hospital of Shandong University, Jinan, Shandong, ChinaDepartment of Obstetrics and Gynecology, Qilu Hospital of Shandong University, Jinan, Shandong, ChinaDepartment of Obstetrics and Gynecology, Qilu Hospital of Shandong University, Jinan, Shandong, ChinaDepartment of Obstetrics and Gynecology, Qilu Hospital of Shandong University, Jinan, Shandong, China
