Purpose To investigate the incidence of Tubal Ectopic Pregnancies (TEP) in IVF-ET patients with respect to the status of the fallopian tubes after a previous TEP. Material and methods This retrospective study compares patients undergoing 481 IVF-ET cycles after conservatively or surgically treated TEP(s) with a Control Group (idiopathic or male factor for IVF-ET indication). Medical reports of surgery and/or hysterosalpingograms prior to the IVF cycles classified the status of the fallopian tubes. Results 12 TEPs (8.95%/Pregnancies (PR)) occurred in the Study Group. In the Control Group one TEP (0.75%/PR; p<0.001) was found. Smoking increased the probability of TEPs (p=0.0028) and of pathological pregnancies (abortion, biochemical and ectopic PR; (p=0.0411)). For statistic evolution logistic regression (PROC GENMOD) and a repeated measure model were applied. Conclusion Women with a previous TEP should be informed about the significantly increased risk for a further TEP in IVF-ET treatment, especially if they are smoking.
Abstract. Women with endometrial cancer often undergo hysteroscopy during their diagnostic work-up. Whether or not the duration of hysteroscopy affects the rate of positive peritoneal cells and the duration of recurrence-free survival is unknown. In a retrospective multi-centre study, the records of 552 patients with endometrial cancer were investigated. Duration of hysteroscopy was correlated with clinicopathological parameters and patient survival data. The mean [standard deviation (SD)] duration of hysteroscopy was 18.2 (10.5) min in the study population and 17.9 (10.1) min and 17.9 (10.2) min in patients with positive (n=109) and negative peritoneal cytology (n=443), respectively (p=0.9). There were no statistically significant correlations between duration of hysteroscopy and positive peritoneal cytology (p=0.6; rho=-0.028), FIGO stage (p=0.2; rho=-0.080), lymph node involvement (p=0.2; rho=0.106) and patient age (p=0.5; rho=0.033). Longer duration of hysteroscopy (>15 min) was not associated with positive peritoneal cytology (yes vs. no, p=0.8), advanced tumour stage (FIGO I vs. II, III and IV, p=0.3), lymph node involvement (yes vs. no, p=0.1) and patient age (≤65 vs. >65 years, p=0.4). In a multivariate analysis, FIGO stage [p<0.0001; hazard ratio (HR)=5.1, 95% confidence interval (CI) 2.5-10.2], lymph node involvement (p=0.02; HR=3.2, 95% CI 1.2-8.8) and patient age (p=0.003; HR=2.4, 95% CI 1.3-4.2), but not duration of hysteroscopy (p=0.4; HR=1.2, 95% CI 0.7-2.2), were associated with recurrence-free survival. We conclude that longer duration of hysteroscopy does not increase the risk of positive peritoneal cytology and it is not an adverse prognostic factor for recurrence-free survival in patients with endometrial cancer.
The observed weekly rhythm for oocyte pick-ups is certainly due to preprogrammed ovarian stimulation used in our IVF programs. Age as well as the number of embryos transferred are the main influencing factors on a positive outcome and more predictive than seasonal aspects.
Although the fertilization rate of oocytes and the pregnancy rate were not significantly different between smokers and nonsmokers, we found significantly alterated hormonal parameters and negatively influenced oocyte parameters, particularly after clomiphene stimulation. So we might consider using only GnRHa protocols for smoking patients. Additionally, we advise our patients to stop smoking before an IVF-ET treatment because of the complex effects of smoking on the reproductive and hormonal system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
