Influence of the time interval between hysteroscopy, dilation and curettage, and hysterectomy on survival in patients with endometrial cancer.

摘要

OBJECTIVE: To evaluate whether a prolonged time interval between dilation and curettage (D&C) and hysterectomy has an effect on survival in patients with surgically treated endometrial cancer. METHODS: In this multicenter study, time between D&C and hysterectomy was correlated to clinical data in 344 surgically staged patients with endometrioid endometrial cancer. RESULTS: The median (interquartile range) interval between D&C and hysterectomy in patients with endometrial cancer was 23 (13-34) days. In a univariable survival analysis, International Federation of Gynecology and Obstetrics (FIGO) tumor stage (P<.001, P<.001), tumor grade (P<.001, P<.001), and patients' age (P<.001, P<.001), but not time interval from D&C to hysterectomy (P=.06, P=.07) were associated with disease-free and overall survival, respectively. In a multivariable Cox regression model, FIGO tumor stage (P<.001, P<.001), and patients' age (P<.001, P<.001) but not tumor grade (P=.4, P=.2) or time interval between D&C and hysterectomy (P=.5, P=.8) were independent prognostic factors for disease-free and overall survival, respectively. CONCLUSION: We were not able to show that a prolonged time interval between D&C and hysterectomy has a significant effect on the prognosis of patients with endometrial cancer. LEVEL OF EVIDENCE: II.
