Factors predicting recurrence in patients with stage IA endometrioid endometrial cancer: what is the importance of LVSI?

PURPOSE: The aim of this study is to define the clinical and pathological prognostic factors for recurrence and to evaluate the recurrence patterns and adjuvant therapies used in this group of patients with stage IA endometrioid type endometrial cancer (FIGO 2009-International Federation of Gynecology and Obstetrics). METHODS: Among the patients with epithelial endometrial cancer operated between January 1993 and May 2013 in a single institution, 720 patients with stage IA endometrioid endometrial cancer were included. Patients with a tumor type of serous, clear cell, mucinous, undifferentiated, and mixed type and with a tumor containing sarcomatous component and the patients with a secondary primer cancer were excluded from the study. RESULTS: Lympho-vascular space invasion (LVSI) was present in 60 (8.3%) patients. Pelvic and para-aortic lymphadenectomy was performed in 266 (36.9%) patients. Median follow-up time was 48 months (range 3-240). Recurrence occurred in 23 (3.4%) patients and 6 (0.9%) died of disease. The median time-to recurrence (TTR) was 24 months (range 4-52 months) in the patients with recurrence. LVSI was associated with recurrence in the univariate analysis. Five-year disease-free survival (DFS) decreased from 96.8 to 80.1% in the presence of LVSI (p < 0.001). This association could not be shown in patients who had had lymphadenectomy (p = 0.136). Extra-pelvic recurrence occurred in 6.7% and 1% of the patients with and without LVSI, respectively, (p = 0.001). Any independent prognostic factor could not be detected in the multivariate analysis. CONCLUSIONS: Only LVSI and tumor grade were associated with DFS and disease-specific survival (DSS), respectively, in the 686 patients with stage IA endometrial cancer in the univariate analysis, since these associations could not be shown in multivariate analysis.

Nifedipine increases fetoplacental perfusion.

AIM: Our aim is to evaluate the effect of nifedipine on fetoplacental hemodynamic parameters. METHODS: A retrospective study was conducted at a tertiary center with 30 patients for whom nifedipine treatment was used as a tocolytic therapy for preterm labor. Initiation of this treatment was at 31.6±2.5 weeks of gestation. We combined the pulse Doppler imaging parameters with grayscale imaging via the Bernoulli theorem, which is called the "continuity equation", to get the fetoplacental perfusion (FPP). Evaluated parameters were the resistance index (RI), the pulsatility index (PI), systole/diastole ratios (S/D), the velocity-time integral of the umbilical artery (VTI), the radius of the umbilical artery, the peak systolic velocity and the mean pressure gradient in the umbilical artery. From these parameters, the FPP was acquired. RESULTS: We found that the RI, the PI and the S/D ratio did not change after treatment with nifedipine. The mean pressure gradient, the VTI and the peak systolic velocity increased after treatment with nifedipine. Nifedipine increases FPP from 166±73.81 beat.cm3/min to 220±83.3 beat.cm3/min. DISCUSSION: Although nifedipine had no effect on the PI, the RI or the S/D, it increased the mean pressure gradient, the VTI and FPP.

Obstetric outcomes of isolated oligohydramnios during early-term, full-term and late-term periods and determination of optimal timing of delivery.

AIM: Our aim was to evaluate the obstetric outcomes of isolated oligohydramnios during the early-term, full-term, and late-term periods, and to determine the optimal timing of delivery. METHODS: A retrospective study was performed at a tertiary center. Isolated oligohydramnios cases were divided into early-term, full-term, and late-term groups. Evaluated outcomes were fetal birthweight, 5-min Apgar score < 7, meconium-stained amniotic fluid, neonatal intensive care unit admission, transient tachypnea of newborn (TTN), requirement of ventilator, newborn jaundice, mode of delivery, induction of labor, and undiagnosed small-for-gestational-age fetus before delivery. Composite outcome was defined as perinatal outcomes taken together (neonatal intensive care unit admission, TTN, requirement of ventilator, and newborn jaundice). RESULTS: The study period included 1213 cases of term isolated oligohydramnios. Within this cohort there were 347 early-term, 781 full-term and 85 late-term patients. The cesarean rate and the rate of newborn jaundice were higher in early-term cases (37.8% and 3.5%, respectively) than in full-term cases (30.1% and 0.9%, respectively). Meconium-stained amniotic fluid was higher in late-term than full-term cases. Timing of delivery did not affect occurrence of TTN, 5-min Apgar score < 7, ventilator requirement, or composite outcome. In total, 15-17% of isolated oligohydramnios cases involved undetected small-for-gestational-age fetuses. CONCLUSION: As this study was not a randomized controlled trial, a decisive conclusion may not be possible. However, until well-designed controlled studies are conducted, expectant management may be appropriate up to the full-term period and induction of labor may be appropriate management when the full-term period is reached.

Risk factors for clavicle fracture concurrent with brachial plexus injury.

PURPOSE: The aim of this study was to evaluate the risk factors for clavicle fracture concurrent with brachial plexus injuries. METHODS: A retrospective study was conducted at a tertiary centre. The hospital records of 62,288 vaginal deliveries were evaluated retrospectively. There were 35 cases of brachial plexus injury. Of these patients, nine had brachial plexus injuries with clavicle fracture and 26 without clavicle fracture. The analysed risk factors for clavicle fracture concurrent with brachial plexus injury were gestational diabetes, labour induction and augmentation, prolonged second stage of labour, estimated foetal weight above 4000 g, birth weight above 4000 g, risky working hours, and the requirement of manoeuvres to free the impacted shoulder from behind the symphysis pubis. RESULTS: Labour augmentation with oxytocin increased the risk of clavicle fracture in cases of brachial plexus injury (OR 6.67; 95% CI 1.26-35.03). A birth weight higher than 4000 g also increased the risk of clavicle fracture. Risky working hours, gestational diabetes, estimated foetal weight higher than 4000 g, and requirement of shoulder dystocia manoeuvres did not increase the risk of clavicle fracture. CONCLUSIONS: Labour augmentation and actual birth weight higher than 4000 g were identified as risk factors for clavicle fracture in cases of brachial plexus injury.

The Effect of the Amniotic Fluid Index on the Accuracy of Ultrasonographic-Estimated Fetal Weight.

BACKGROUND: Fetal weight estimation is one of the most important aspects of antenatal care. The effects of amniotic fluid volume on the accuracy of estimated fetal weight (EFW) depend on the amount of fluid, in particular whether it is polyhydramnios or oligohydramnios. Previous studies have reported conflicting results of the effects of amniotic fluid volume on EFW accuracy. AIM: The aim of the study was to evaluate the effects of isolated oligohydramnios cases and polyhydramnios on the accuracy of EFW. MATERIALS AND METHODS: A retrospective study was conducted at a tertiary center. The study groups consisted of 1069 term isolated oligohydramnios cases, 182 term isolated polyhydramnios cases, and 392 term-matched cases with a normal volume of amniotic fluid. Estimated fetal weight error was determined and expressed in terms of systematic error, calculated from mean percentage error and random error. RESULTS: The systematic error did not differ significantly between polyhydramnios and oligohydramnios cases (-3.60 [8.94%] vs -2.73 [9.7%]). The random error was 8.94% in polyhydramnios cases and 9.7% in oligohydramnios cases. The overestimation rate was 63.6% in polyhydramnios cases and 66.3% in oligohydramnios cases. CONCLUSIONS: There were no significant differences in the accuracy of EFW between oligohydramnios and polyhydramnios. However, there was a tendency for overestimation in both types of cases.
