RESUMO

OBJECTIVE: The aim of this study was to investigate the performance of screening for open spina bifida (OSB) integrated into the routine first-trimester screening. METHOD: This is a prospective multicentre study of 4,755 women undergoing first-trimester ultrasound scans over a 4-year period. Measurements of the brainstem (BS) diameter and brainstem-to-occipital-bone (BSOB) distance were performed. The cisterna magna (CM) was measured in the tilted axial view. RESULTS: Pregnancy outcome data were available for 4,658 fetuses included in this study. There were 5 fetuses with OSB, and in all of them, the BS/BSOB ratio and the CM measurements were abnormal. The sensitivity and specificity of a BS/BSOB ratio >1 were 100%. The sensitivity of a CM width <5th centile was 100%, and the specificity was 95.1%. In 4.6% of cases, the BS/BSOB ratio was between the 95th percentile and 1. In 87.1% of these cases, the CM was normal, and 12.9% had a CM below the 5th percentile. CONCLUSION: Screening for OSB is feasible in routine first-trimester scans. The BS/BSOB ratio shows a very good sensitivity and specificity. In cases with near-normal values for the BS/BSOB ratio, the CM width might be helpful for further assessment.

RESUMO

PURPOSE: Human papillomavirus (HPV) can cause condylomata acuminata, also known as genital warts. Our aim was to evaluate the long-term recurrence of genital warts after primary carbon dioxide laser treatment before the introduction of the vaccination against HPV. METHODS: Recurrence rate and localization of genital warts were analysed in a retrospective study in 1798 women presenting with a new diagnosis of genital warts from 1992 to 2009 at a University hospital and had received laser treatment. Additionally, data on topography, pregnancy status, and cervical smear were available for women treated from 2003 to 2009 (n = 825, data subset 1) and systematic follow-up data for women treated in 2006 and 2007 (n = 242, data subset 2). RESULTS: Median time from laser treatment to first recurrence was 14.6 weeks (data subset 2). The site most affected was the vulva (90.7%) followed by the perineum/perianal region (59.3%) and the vagina (47.3%). Abnormal Pap smear was observed in 22.6%. Systematic follow-up with a median follow-up time of 3.1 years revealed at least one recurrence in 68 (28.1%) of 242 women. Women with multifocal genital warts had a 2.9 times increased risk for recurrence compared to women with unifocal lesions (p = 0.01). CONCLUSIONS: Nearly 30% of women presenting with genital warts experienced at least one recurrence after treatment with carbon dioxide laser. Multifocal lesions are the strongest indicator of recurrence. These data provide an important insight to recurrence rates of genital warts before HPV vaccination and underline the significance of a long-term follow-up and HPV vaccination.

RESUMO

Recently L1CAM was shown to be a promising biomarker for early-stage endometrial carcinoma (EC). As L1CAM expression was found to be related to serous ECs and areas of serous differentiation in endometrioid carcinomas, there is evidence that L1CAM-positive cancers more likely resemble type II carcinomas. Furthermore, expression of growth factor receptor HER2 has been found to be closely associated with serous ECs. We conducted a retrospective study on 142 patients in FIGO stages I and II with endometrioid EC and analyzed L1CAM and HER2 expression by double-staining immunohistochemistry. The association between these 2 transmembrane molecules and their impact on patient outcome was analyzed. Both L1CAM and HER2 showed a significant association with recurrent disease (P<0.001 and P=0.007, respectively). We found 39 (27%) L1CAM-positive cases and 17 (12%) HER2-positive cases. About 6.3% of cases were positive for both biomarkers. Survival of L1CAM-positive patients showed a significant difference between HER2-positive and HER2-negative patients (P=0.019) regarding disease-free survival. The most unfavorable disease-free survival and overall survival was found for patients with L1CAM and HER2 double-positive tumors (P<0.001). Double immunostaining revealed a mutually exclusive staining pattern for L1CAM and HER2 expression on the level of tumor cells. In early endometrioid uterine carcinoma, an additional expression of HER2 to L1CAM seems to further worsen disease-free survival and overall survival. In terms of "personalized medicine," detection of these molecules in endometrioid ECs may open new avenues for targeted therapies with the newly available anti-HER2 drugs and/or with the upcoming humanized anti-L1CAM antibodies.

RESUMO

BACKGROUND: The purpose of this study was to evaluate serum HE4 as a biomarker to detect recurrent disease during follow-up of patients with endometrial adenocarcinoma (EAC). METHODS: We performed a retrospective analysis of 98 EAC patients treated at Innsbruck Medical University, between 1999 and 2009. Twenty-six patients developed recurrent disease. Median follow-up was 5 years. Serum HE4 and CA125 levels were analyzed using the ARCHITECT assay (Abbott, Wiesbaden, Germany) pre-operatively (baseline), post-operative (interval) and after histological confirmation of recurrent disease or when patients returned for clinical review with no evidence of recurrent disease (recurrence/final)). Receiver operator curves (ROC), Spearman rank correlation coefficient, chi-squared and Mann-Whitney tests were used for statistical analysis. RESULTS: HE4 levels decreased after initial treatment (p = 0.001) and increased again at recurrence (p = 0.002). HE4 was elevated (>70 pmol/L) in 21 of 26 (81%) and CA125 was elevated (>35 U/ml) in 12 of 26 (46%) patients at recurrence. In endometrioid histology (n = 69) serum HE4 measured during follow up (Area under the curve (AUC) = 0.87, 95%CI 0.79-0.95) was a better indicator of recurrence than CA125 (AUC = 0.67, 95%CI 0.52-0.83). A HE4 level of 70 pmol/L was associated with a sensitivity of 84%, a specificity of 74% and a negative predictive value of 93% when assessing for recurrent endometrioid EAC. CONCLUSION: This is a preliminary description of HE4 serum levels measured during routine follow up of EAC patients. Serum HE4 measured during clinical follow-up may identify recurrent disease particularly in patients with endometrioid histology. Further prospective validation of HE4 is warranted.

RESUMO

AIM: To develop and validate a biomarker-based index to optimize referral and diagnosis of patients with suspected ovarian cancer. Furthermore, to compare this new index with the Risk of Malignancy Index (RMI) and Risk of Ovarian Malignancy Algorithm (ROMA). PATIENTS AND METHODS: A training study, consisting of patients with benign ovarian disease (n=809) and ovarian cancer (n=246), was used to develop the Copenhagen Index (CPH-I) utilizing the variables serum HE4, serum CA125 and patient age. Eight international studies provided the validation population; comprising 1060 patients with benign ovarian masses and 550 patients with ovarian cancer. RESULTS: Overall, 2665 patients were included. CPH-I was highly significant in discriminating benign from malignant ovarian disease. At the defined cut-off of 0.070 for CPH-I the sensitivity and specificity were 95.0% and 78.4% respectively in the training cohort and 82.0% and 88.4% in the validation cohort. Comparison of CPH-I, ROMA and RMI demonstrated area-under-curve (AUC) at 0.960, 0.954 and 0.959 respectively in the training study and 0.951, 0.953 and 0.935 respectively in the validation study. Using a sensitivity of 95.0%, the specificities for CPH-I, ROMA and RMI in the training cohort were 78.4%, 71.7% and 81.5% respectively, and in the validation cohort 67.3%, 70.7% and 69.5% respectively. CONCLUSION: All three indices perform well at the clinically relevant sensitivity of 95%, but CPH-I, unlike RMI and ROMA, is independent of ultrasound and menopausal status, and may provide a simple index to optimize referral of women with suspected ovarian cancer.

RESUMO

OBJECTIVE: To investigate the impact of advanced maternal age on the rate of perinatal mortality. DESIGN: Retrospective cohort study including all 56,517 singleton hospital deliveries between 1999 and 2008. METHODS: Data were analyzed according to maternal age at delivery in 3 groups of women, 25-34 years, 35-39 years and ≥ 40 years, using the youngest as the reference group. RESULTS: Odds ratios (ORs) for antenatal deaths were 0.98 (CI: 0.67-1.43) and 2.57 (CI: 1.57-4.22) for age groups 35-39 years and ≥ 40 years, respectively. Significant differences in neonatal mortality rates between the age groups were not found. Significant amendable risk factors were attendance of <4 health care visits (OR = 15.55, CI: 9.47-25.51 in age group 35-39 years; OR = 16.38, CI: 9.78-27.43 in the age group ≥ 40 years) and obesity (OR = 1.85, CI: 1.27-2.70 in age group 35-39 years; OR = 1.83, CI: 1.22-2.74 in the age group ≥ 40 years). In the multivariate regression analysis, the adjusted ORs for perinatal mortality were 1.03 (95% CI: 0.77-1.39) and 1.66 (95% CI: 1.03-2.66) for age groups 35-39 and ≥ 40, respectively. CONCLUSIONS: Women older than 40 years carry an increased risk for stillbirth. Important amendable risk factors are obesity and poor antenatal care.

RESUMO

OBJECTIVE: This study aimed to demonstrate the superiority of cryocompression over cryotherapy alone in the prevention of chemotherapy-induced peripheral neuropathy (CIPN) grade 2 or above. METHODS: This prospective randomized study was conducted between May 2020 and January 2023 in Innsbruck. Eligible patients had a diagnosis of gynecological cancer and received a minimum of 3 cycles of taxane-based CT (neoadjuvant, adjuvant or palliative therapy). Patients were randomized 1:1 to receive either cryotherapy or cryocompression on their upper extremities during chemotherapy (CT). We performed temperature measurements, two QoL questionnaires and neurological tests during CT and at follow-up 3 and 6-9 months after the completion of CT. CIPN was assessed using the CTCAE score. RESULTS: Of 200 patients recruited, both groups showed a lower prevalence of CIPN in this study compared to recent literature. In the group receiving cryotherapy, the prevalence of grade 1 CIPN was 30.1 %, and that of grade 2 CIPN or above was 13.7 %; in the group treated with cryocompression, the prevalence of grade 1 CIPN was 32.8 %, and that of grade 2 or above CIPN was 17.2 %. We found a significant reduction in temperature in the cryotherapy and cryocompression groups. Regarding the two QOL questionnaires as well as the neurological tests no significant differences were found between the two groups. CONCLUSION: Our study suggests that cryotherapy as well as cryocompression is a safe and effective way to cool patients' extremities to lower the prevalence of CIPN. Cryocompression was not more effective than cryotherapy alone in the prevention of CIPN.

RESUMO

OBJECTIVE: To evaluate the prognostic value of pretherapeutic serum HE4 in endometrial cancer in comparison to CA125. METHODS: HE4 and CA125 serum levels were analyzed by means of chemiluminescent microparticle immunoassays in 183 patients with endometrial cancer treated at the Department of Obstetrics and Gynecology, Innsbruck Medical University, between 1999 and 2009. The Kaplan-Meier method and Cox's proportional hazards analysis were performed to determine the prognostic significance of HE4, CA125 and the combination of both markers. RESULTS: In univariate analysis both markers, HE4 and CA125, were of prognostic value for overall survival (p<0.001 and p=0.028) and disease-free survival (p=0.015 and p=0.045). In multivariate analysis HE4 was seen to have independent prognostic value in overall survival (HR 2.407, p=0.017) in contrast to CA125. The combination of both markers showed a higher hazard ratio (HR 4.04, p=0.023) for overall survival in comparison to HE4 alone. In the subgroup endometrioid histological type (n=132) only HE4 was of prognostic value for overall survival in univariate (p=0.001) and multivariate analysis (p=0.023). CONCLUSIONS: Pretherapeutic serum HE4 levels alone and in combination with CA125 are an independent prognostic marker in endometrial cancer patients.

RESUMO

This study was designed to investigate the DNA-methylation status of E-cadherin (CDH1) and H-cadherin (CDH13) in serum samples of cervical cancer patients and control patients with no malignant diseases and to evaluate the clinical utility of these markers. DNA-methylation status of CDH1 and CDH13 was analyzed by means of MethyLight-technology in serum samples from 49 cervical cancer patients and 40 patients with diseases other than cancer. To compare this methylation analysis with another technique, we analyzed the samples with a denaturing high performance liquid chromatography (DHPLC) PCR-method. The specificity and sensitivity of CDH1 DNA-methylation measured by MethyLight was 75% and 55%, and for CDH13 DNA-methylation 95% and 10%. We identified a specificity of 92.5% and a sensitivity of only 27% for the CDH1 DHPLC-PCR analysis. Multivariate analysis showed that serum CDH1 methylation-positive patients had a 7.8-fold risk for death (95% CI: 2.2-27.7; p = 0.001) and a 92.8-fold risk for relapse (95% CI: 3.9-2207.1; p = 0.005). We concluded that the serological detection of CDH1 and CDH13 DNA-hypermethylation is not an ideal diagnostic tool due to low diagnostic specificity and sensitivity. However, it was validated that CDH1 methylation analysis in serum samples may be of potential use as a prognostic marker for cervical cancer patients.

RESUMO

Introduction HE4 and CA 125, two established biomarkers for assessing adnexal masses in non-pregnant women, are hardly investigated in pregnancy, especially in pregnancy-associated conditions. The aim was to evaluate HE4 and CA 125 levels in the course of pregnancy and to assess the impact of pregnancy disorders, contractions and rupture of membranes on HE4 and CA 125 serum levels in order to use these parameters for evaluation of adnexal masses in pregnancy. Patients and Methods Blood samples (n = 238) of 201 women seen at the Medical University of Innsbruck, Austria, were prospectively obtained during pregnancy and postpartum. Serum concentrations of HE4 and CA 125 were analyzed. ROMA index was calculated by the premenopausal formula. Results HE4 serum levels were highest in the third trimester. Contractions (p < 0.001), rupture of membranes (p = 0.005) and pregnancy-associated diseases (p = 0.003) were associated with higher HE4 levels. As much as 97.5% of HE4 measurements remained below the recommended cut-off for premenopausal women (70 pmol/l). CA 125 levels were not altered by pregnancy-associated conditions. Generally, CA 125 exhibited a wider serum level variability, exceeding the established cut-off of 35 U/ml in 16.4%. Conclusions HE4 serum levels are influenced by several pregnancy-related conditions leading to significantly higher levels in these cases. Despite differing medians according to trimester, the 95th percentile cut-offs and almost all maximum values during the entire course of pregnancy were below the established cut-off for premenopausal women. It was also superior to the performance of ROMA index. Therefore, HE4 can be used as a valuable negative predictive marker for the assessment of adnexal masses during pregnancy.
