RESUMEN

The present study aims to evaluate the pretherapeutic Fibrinogen-Albumin-Ratio Index (FARI), as currently reliable biomarkers to predict therapy response and prognosis of patients with advanced vulvar cancer are missing. Data of 124 consecutive patients, who underwent primary resection for vulvar cancer ≥ pT1b, were retrospectively analyzed. Associations between the FARI and disease recurrence were assessed fitting receiver operating characteristics (ROC) and binary logistic regression models; univariate and multivariable Cox regression models for disease-specific survival (DSS) and progression-free survival (PFS) were performed. A pretherapeutic low FARI cut at its median (<9.67) is significantly associated with younger age (65.5 vs. 74.0 years) and higher risk of recurrence (52.4% vs. 26.2%). The ROC analysis calculates the area under the curve (AUC) of the FARI for a PFS < 6 months of 0.700 and for a DSS < 12 months of 0.706, outperforming fibrinogen and albumin alone. The FARI remained independently predictive for PFS (HR 0.84, 95% CI [0.99−1.03], p = 0.009) and DSS (HR 0.82, 95% CI [0.70−0.99], p = 0.019), also in multivariable survival analysis. Despite the FARI's promising predictive and prognostic value, however, further elucidation of its precise mode of action is warranted before clinical application as it appears to rely only on subtle changes of fibrinogen levels.

RESUMEN

Increased uterine artery Doppler indices have been shown to be associated with preeclampsia and adverse pregnancy outcomes in singleton and twin pregnancies. At 20-22 weeks of gestation, we assessed the use of notching, the highest, lowest, and mean pulsatility index (PI), and the combination of notching and PI of the uterine arteries to screen for preeclampsia. This was done in a cohort of 380 twin pregnancies. The results showed that the combination of notching and the highest PI above the 95th centile of the uterine arteries gives the best screening characteristics for preeclampsia in twin pregnancies. We calculated sensitivities for preeclampsia for notching, highest PI, and the combination of notching and the highest PI of 50%, 45% and 91%, with specificities of 96%, 96% and 93%, respectively. The present findings demonstrate that notching, increased highest PI, and the combination of notching and the highest PI of the uterine arteries is associated with an increased risk of preeclampsia in twin pregnancies. We observed the highest sensitivity and specificity by using the combination of notching and the highest PI of the uterine arteries.

RESUMEN

Aim of this study was to investigate the histologic outcome of cervical intraepithelial neoplasia (CIN) during observational management. Consecutive women with histologically verified CIN and observational management were included. Histologic findings of initial and follow-up visits were collected and persistence, progression and regression rates at end of observational period were assessed. Uni- and multivariate analyses were performed. A systematic review of the literature and meta-analysis was performed. In 783 women CIN I, II, and III was diagnosed by colposcopically guided biopsy in 42.5%, 26.6% and 30.9%, respectively. Younger patients had higher rates of regression (p < 0.001) and complete remission (< 0.001) and lower rates of progression (p = 0.003). Among women aged < 25, 25 < 30, 30 < 35, 35 < 40 years, and > 40 years, regression rates were 44.7%, 33.7%, 30.9%, 27.3%, and 24.9%, respectively. Pooled analysis of published data showed similar results. Multivariable analysis showed that with each five years of age, the odds for regression reduced by 21% (p < 0.001) independently of CIN grade (p < 0.001), and presence of HPV high-risk infection (p < 0.001). Patient's age has a considerable influence on the natural history of CIN - independent of CIN grade and HPV high-risk infection. Observational management should be considered for selected young patients with CIN.

RESUMEN

PURPOSE: To evaluate the effect of gestational diabetes on omentin-1 in maternal and cord plasma. As a potent mediator of insulin resistance, Omentin-1, an adipokine derived from human adipose and placental tissue, may be an important player in the pathophysiology of gestational diabetes. METHODS: This was a prospective case-control study. The study included 96 women with gestational diabetes and 96 pregnant women without. Omentin-1 was measured at the time of the oral glucose tolerance test, at 32 weeks in maternal plasma and right after delivery in umbilical cord blood by ELISA assay. RESULTS: Over a period of 2 years, 200 patients were enrolled. Omentin-1 levels did not significantly differ between both groups throughout the pregnancy: omentin-1 levels were 157 ± 83 ng/ml in women with gestational diabetes and 158 ± 93 ng/ml in women without gestational diabetes (p = 0.94) at time of the oral glucose tolerance test and 118 ± 77 ng/ml in women with diabetes and 150 ± 89 ng/ml in women without (p = 0.12) at 32 weeks, respectively. Both groups showed a decrease in omentin-1 levels throughout pregnancy, with a more pronounced decrease in diabetic women (13 ± 53 versus 4 ± 48 ng/ml; p = 0.5). Neonatal omentin-1 levels were significantly lower in offspring of diabetic mothers: 106 ± 61 versus 134 ± 45 ng/ml (p = 0.03). CONCLUSIONS: There was no significant difference in omentin-1 levels between healthy and diabetic mothers throughout the pregnancy. However, we found significantly lower omentin-1 levels in offspring of diabetic mothers. This may indicate a risk for the development of insulin resistance in later life.

RESUMEN

Fibrinogen has an important pathophysiological role in tumor cell progression and development of metastases in different types of cancer. The present study aimed to evaluate the role of pre-treatment fibrinogen plasma concentrations as a biomarker for tumor biology and prognosis in patients with uterine leiomyosarcoma (ULMS). Clinical data of patients with ULMS were assessed in this multi-center study Pre-therapeutic fibrinogen plasma concentrations were evaluated. We investigated the association between fibrinogen plasma levels and clinico-pathological parameters and performed univariate and multivariable survival analyses. In total, 70 women with ULMS were included into the analysis. Mean (SD) pre-treatment fibrinogen plasma levels were 480.2 (172.3) mg/dL. Patients with advanced tumor stage, increased tumor size and higher histological grading had higher fibrinogen levels (p = 0.02, p = 0.013, and p = 0.029, respectively). In ULMS patients with increased fibrinogen levels 5-year overall survival (OS) rates were 25.0% compared to 52.9% in ULMS patients with normal fibrinogen, respectively. Univariate survival analyses revealed that elevated fibrinogen plasma levels (p = 0.030), advanced tumor stage (p < 0.001) and undifferentiated histology (p = 0.003) showed association with unfavorable OS. In multivariable analysis, histological grade (p = 0.03) and tumor stage (0.02) were independently associated with survival. Elevated fibrinogen plasma levels were associated with aggressive tumor biology and poor prognosis in women with ULMS. Fibrinogen might be useful as a novel biomarker in ULMS.

RESUMEN

Gamma-glutamyltransferase (GGT) is an established marker for proliferative/apoptotic balance and has been associated with cancer risk and prognosis. The aim of this study was to evaluate the value of pre-treatment GGT serum levels as prognostic biomarker in patients with primary uterine leiomyosarcoma (ULMS). Data of women with ULMS were extracted from a multi-center database. Pre-treatment GGT serum levels were measured and patients assigned to predefined GGT risk groups. GGT values were correlated with clinico-pathological parameters and univariate and multivariable survival analyses were performed. A total of 44 patients with ULMS were analyzed. Mean (SD) pre-therapeutic GGT serum level was 33.8 (39.8) U/L. In Figo Stage I versus II-IV mean (SD) GGT values were 28.8 (34.0) U/l and 43.5 (49.2) U/l, respectively (p = 0.25). Five-year overall survival (OS) rates in ULMS patients with normal low versus higher GGT levels were 70% and 37%, respectively (p = 0.043). Univariate and multivariable analyses revealed that higher GGT serum levels (p = 0.043, p = 0.005) and high histological grade (p = 0.029, p = 0.012) were independently associated with impaired OS, respectively. Higher pre-treatment GGT serum levels were independently associated with unfavorable prognosis in women with ULMS. Thus, GGT seems to be a useful novel biomarker in ULMS.
