This retrospective cohort study determined the relative efficacy of blastocyst and cleavage-stage transfers in patients with differing numbers of zygotes. A total of 1116 women whose embryo transfers were planned independently of patient characteristics were included. Cleavage-stage (D3) and blastocyst-stage (D5) transfer outcomes were analyzed per number of zygotes. The D5 group included transfer cancellations as the intention-to-treat population. The effect of the embryo transfer date on the clinical outcomes (clinical pregnancy and implantation rates) was analyzed using multivariate logistic regression. Among the patients, 584 and 532 underwent D3 and D5 embryo transfers, respectively. The clinical pregnancy rates were significantly higher in D5 patients with ≥ 6 zygotes (25.7% vs 48.3%). The multivariate logistic regression analysis for clinical pregnancy did not show significant differences between the blastocyst and cleavage-stage transfers in patients with ≤ 5 zygotes (0.874 [0.635-1.204]). Compared to the cleavage-stage, blastocyst-stage transfers for patients with ≥ 6 zygotes resulted in a three-fold increase in clinical pregnancy rates (3.122 [1.797-5.425]). Blastocyst transfers were not inferior to cleavage-stage embryo transfers among patients with few zygotes and were preferable for patients with several zygotes.

PubMedID: 24435497 Objective: This study aimed at determining if tumor-free distance (TFD) from outermost layer of cervix predicts surgicopathologic factors and outcome in surgically treated cervical cancer patients. Materials and methods: One hundred sixteen surgically treated cervical squamous cell carcinomas between 1991 and 2010 with FIGO stage IB/2A were identified and reevaluated histologically regarding the TFD. TFD was defined as the distance between outermost layer of cervix and deepest cervical stromal invasion. Depth of invasion (DOI) and TFD were expressed as continuous variables and compared with traditional surgicopathologic variables and survival to determine their prognostic significance. Results: The mean DOI was 10.3 mm and the mean TFD was 4.2 mm. The most common stage was IB1 (60 patients, 51.7%). The mean number of removed pelvic lymph nodes was 32.2 (median 30; range 8-78). Positive pelvic lymph nodes were found in 27 (23%) of the patients. Sixty-eight patients had lymphovascular space involvement (LVSI). Sixty-eight patients (59%) received postoperative radiotherapy where the following items were present: tumor diameter >4 cm, positive lymph nodes, LVSI and positive surgical margins. With the median fol-low- up of 53 months (3-219 months); 14 patients had local and 13 patients had distant metastases (5 of the patients had both at the time of recurrence). With logistic regression analysis, TFD was a predictor of pelvic lymph involvement ( p=0.028) and LVSI (p=0.008) while DOI was a predictor of LVSI (p=0.044). In Cox regression analysis, increased TFD was associated with improved disease-free survival (DFS) (p=0.007). DFS curves (for TFD cut off value 2.5 mm) according to Kaplan-Meier were found to be statistically significant (log rank test=0.002). Conclusion: The results indicate that TFD is predictive of pelvic lymph node involvement, LVSI and patient outcome in surgically treated cervical cancer patients. However, prospective measurement of TFD is still necessary to determine its value in clinical practice. © Springer-Verlag 2014.

This report describes the use of in vitro oocyte maturation in two patients with history of repeated oocyte maturation arrest (OMA) from in vitro fertilization. Based on these two cases, in vitro oocyte maturation from unstimulated cycles seems not an alternative treatment option for the patients with history of OMA. © 2011 Springer-Verlag.
