ABSTRACT
Objective To investigate the relationship between perineural invasion (PNI) and the clinicopathological features of cervical cancer,and to explore its influence on the prognosis of cervical cancer patients.Methods Retrospective analysis the clinical data of 76 patients with early cervical cancer who received radical hysterectomy + pelvic lymphadenectomy ± paraaortic lymphadenectomy from November 2015 to December 2019 in Xuanwu Hospital.The clinicopathological characteristics of the postoperative pathological results of cervical cancer patients were analyzed to explore the related factors of PNI and its influence on prognosis.Results Single factor analysis suggested that the incidence of PNI was related to tumor diameter,depth of stroma invasion,lymph-vascular space invasion,lymph node metastasis and clinical stage (P ＜ 0.05).Multivariate analysis suggested that the infiltration depth of stroma invasion was the risk factor of PNI (P ＜ 0.05).K-M analysis showed that there was no significant difference in disease-free survival and overall survival between PNI positive and PNI negative patients (P ＞ 0.05).Conclusions PNI is related to the depth of interstitial infiltration.PNI has no significant effect on the short-term recurrence rate and short-term survival rate of cervical cancer patients.
ABSTRACT
Objective To evaluate the role of the fractional dilatation and curettage (D&C) in the diagnosis of atypical hyperplasia of endometrium. Methods The retrospective analysis was performed in 48 patients diagnosed as atypical hyperplasia of endometrium and treated in our hospital from Aug.2009 to Dec.2010. We compared the pathology results of D&C with hysterectomy specimens, and investigated the reasons for the difference. Results The six patients (12.5%) with mild atypical hyperplasia of endometrium still presented with significant pathological changes after D&C (χ2 = 5.90, P＜0.05), 11 cases (22.9%) in 14 patients(29.2%) with moderate atypical hyperplasia (χ2=0.49, P＞0.01), 18 cases (100%) in patents with serious atypical hyperplasia, among which even 8 patients (44.4%) were verified as endometrial cancer. Conclusions There exists pathological discrepancy between the fractional D&C and hysterectomy specimens. Patients with severer atypical hyperplasia may have a higher risk of developing endometrial cancer.
