Surgical stage III endometrial cancer: analysis of treatment outcomes,prognostic factors and failure patterns

OBJECTIVE: The purpose of this study was to evaluate the survival estimates of stage III endometrial cancer patients, and also to detect the prognostic factors and failure patterns. MATERIALS AND METHODS: Sixty-eight surgical Stage III endometrial cancer patients treated at Hacettepe University Hospital were included. All patients underwent surgical staging procedures consisting of peritoneal cytology, infracolic omentectomy, total abdominal hysterectomy, bilateral salpingo-oophorectomy and complete pelvic-paraaortic lymphadenectomy. By surgical staging 26 (38%) patients had Stage IIIA and 42 (62%) patients had Stage IIIC disease. The mean resected lymph node number was 26 (median, 25; range, 15-58). RESULTS: The median age was 60 years (range, 38-77), and the median follow-up period was 62 months (range, 36-90 months). The 5-year disease free survival rate was 58% and the 5-year overall survival rate was 64%. These figures for Stage IIIA were 60% and 68%, respectively; and for Stage IIIC they were 57% and 62%, respectively. No significant survival difference was detected between Stage IIIA and IIIC (p = 0.60 for disease-free survival and p = 0.48 for overall survival). High grade and positive peritoneal cytology predicted poor survival in both univariate (p = 0.004 and p = 0.006, respectively) and multivariate (p = 0.05 and p = 0.04, respectively) analysis. Twenty-eight patients (41%) had recurrence with a median time of 23 months (range, 10-54 months). Nine patients (13%) had only local, 13 patients (19%) had only distant and six patients (9%) had both local and distant relapse. CONCLUSION: Surgical staging is important in the management of Stage III endometrial cancer, and the main problem is still distant failure. In multivariate analysis high grade and positive peritoneal cytology predicted poor survival significantly.     

Influence of insulin resistance on total renin level in normotensive women with polycystic ovary syndrome

OBJECTIVE: To evaluate the influence of insulin resistance on the plasma total renin level in normotensive women with polycystic ovary syndrome (PCOS). DESIGN: Prospective, controlled study. SETTING: University hospital. PATIENT(S): Twenty-five normotensive women with PCOS were compared with 11 normotensive control women with regular cycles and no features of PCOS. INTERVENTION(S): Clinical, ultrasonographic, and hormonal findings were used to define PCOS. Insulin resistance was estimated by continuous infusion of glucose with model assessment in the early follicular phase. MAIN OUTCOME MEASURE(S): Plasma levels of total renin and angiotensin II and serum levels of gonadotropins, DHEAS, total T, free T, 17 alpha-hydroxyprogesterone, and PRL were determined. RESULT(S): Plasma concentrations of angiotensin II were similar in the PCOS group and the control group. The concentration of total renin in plasma was higher in women with PCOS than in healthy women independent of insulin resistance. The sensitivity and specificity of the plasma total renin level to diagnose women with PCOS were calculated as 80% and 71.4%, respectively. CONCLUSION(S): The plasma total renin level is higher in normotensive women with PCOS than in healthy women independent of insulin resistance.     

Does leukocytospermia associate with poor semen parameters and sperm functions in male infertility? The role of different seminal leukocyte concentrations

To investigate the effect of leukocytospermia on standard semen analysis and sperm function tests such as acrosome reaction, hypoosmotic swelling, antisperm antibody binding and cervical mucus penetration, a prospective clinical study was performed. Two hundred and nineteen male infertility patients undergoing investigation and treatment were included in the study. There was a significant association between acrosome reaction positivity and leukocytospermia according to WHO (World Health Organization) criteria. Increased hypoosmotic swelling test score, higher sperm concentration and enhanced acrosome reaction were closely related to leukocytospermia. When the patients were divided into subgroups according to seminal leukocyte concentrations, acrosome reaction and hypoosmotic swelling were observed to be higher in semen samples with higher leukocyte concentrations compared to those with low seminal leukocyte concentration. In addition, higher sperm concentrations were observed in semen samples with increased leukocyte levels compared to semen samples with low leukocyte levels. These results suggest that leukocytospermia may have a favorable effect on some sperm functions at seminal leukocyte concentrations between 1 and 3x10(6)/ml.     

Circadian pattern of spontaneous ventricular tachyarrhythmias in patients with implantable cardioverter defibrillators.

BACKGROUND: Previous studies have reported a circadian variation of ventricular tachyarrhythmias. However, there is no detailed information of the daily distribution of ventricular tachycardia (VT) and ventricular fibrillation (VF) episodes. The purpose of this study was to evaluate the daily distribution of episodes of ventricular tachyarrhythmia in patients with implantable cardioverter defibrillators. MATERIAL/METHODS: We used data stored by last-generation implantable cardioverter-defibrillators (ICD) to retrospectively evaluate the circadian distribution of VT and VF in 70 patients with ICD. The distribution of tachyarrhythmias was categorized into four time zones: zone 1 (06:00-11:59), zone 2 (12:00-17:59), zone 3 (18:00-23:59), and zone 4 (00:00-05:59). RESULTS: During a follow-up of a mean of 3.1+/-1.3 years, a total of 791 ventricular arrhythmias were recorded from which 631 events were VT and 160 VF. A circadian variation of episodes of ventricular tachyarrhythmia was evident. The incidence of ventricular arrhythmia sharply increased in zone 1 (8.82+/-2.13, p<0.0001). Episodes of VT had peaks in zones 1 and 2 (7.44+/-2.03 and 2.70+/-0.65, p<0.001) and episodes of VF had peaks in zones 1 and 4 (1.38+/-0.39 and 1.30+/-0.51, p<0.011). No difference was observed between patients who used betablocker and those who did not. CONCLUSIONS: Malignant ventricular tachyarrhythmias have a circadian distribution. VT peaks occur in the morning and noon hours and VF peaks occurs at the night and morning hours. Betablocker and/or amiodarone usage do not alter this distribution.     

Cardiac biopsy in childhood

Endomyocardial biopsy was attempted in 18 children aged 5 months to 15 years with 82% success. Biopsies obtained from 15 children were examined by light and electron microscope making positive morphological diagnoses in 3 cases. The biopsy findings were actively helpful in 7 other cases, which contrasts with experience in adult biopsy series. This is a low risk procedure which does not add to the hazards of cardiac catheterization in children.
