Risk for pelvic metastasis and role of pelvic lymphadenectomy in node-positive vulvar cancer - results from the AGO-VOP.2 QS vulva study

Simple Summary In node-positive vulvar squamous cell cancer, questions of when and how to perform pelvic lymphadenectomy (LAE) as well as the optimal extent of pelvic treatment in general have been surrounded by considerable controversy. In Germany, systematic pelvic LAE is currently recommended as a staging procedure in patients at risk for pelvic nodal involvement in order to prevent morbidity caused by pelvic radiotherapy (RT) in patients without histologically-confirmed pelvic involvement. However, the population at risk for pelvic metastases remains insufficiently described, resulting in the potential overtreatment of a considerable proportion of patients with groin-positive disease. This applies to the indication to perform surgical staging but also to adjuvant RT of the pelvis without previous pelvic staging. Our study aims to describe the risk for pelvic lymph node metastasis with regard to positive groin nodes and to clarify the indication criteria for pelvic treatment in node-positive vulvar cancer. Abstract The need for pelvic treatment in patients with node-positive vulvar cancer (VSCC) and the value of pelvic lymphadenectomy (LAE) as a staging procedure to plan adjuvant radiotherapy (RT) is controversial. In this retrospective, multicenter analysis, 306 patients with primary node-positive VSCC treated at 33 gynecologic oncology centers in Germany between 2017 and 2019 were analyzed. All patients received surgical staging of the groins; nodal status was as follows: 23.9% (73/306) pN1a, 23.5% (72/306) pN1b, 20.4% (62/306) pN2a/b, and 31.9% (97/306) pN2c/pN3. A total of 35.6% (109/306) received pelvic LAE; pelvic nodal involvement was observed in 18.5%. None of the patients with nodal status pN1a or pN1b and pelvic LAE showed pelvic nodal involvement. Taking only patients with nodal status ≥pN2a into account, the rate of pelvic involvement was 25%. In total, adjuvant RT was applied in 64.4% (197/306). Only half of the pelvic node-positive (N+) patients received adjuvant RT to the pelvis (50%, 10/20 patients); 41.9% (122/291 patients) experienced recurrent disease or died. In patients with histologically-confirmed pelvic metastases after LAE, distant recurrences were most frequently observed (7/20 recurrences). Conclusions: A relevant risk regarding pelvic nodal involvement was observed from nodal status pN2a and higher. Our data support the omission of pelvic treatment in patients with nodal status pN1a and pN1b

Evaluating the Decision-to-Delivery Interval in Emergency Cesarean Sections and its Impact on Neonatal Outcome

Background/Aim: In Germany, performance of an emergency Cesarean section (ECS) is recommended within an interval of <= 20 min from decision to delivery (DDI). The aim of the study was to assess the duration of DDI in ECS as well as its impact on neonatal outcome. Patients and Methods: Data from 437 patients at a single, tertiary care hospital were retrospectively analysed regarding influence on the duration of DDI. Subsequently the impact of DDI on neonatal outcome and incidence of adverse neonatal outcome was analysed. Results: DDI of ECS performed outside core working hours was significantly prolonged (p<0.001). Shorter DDI showed a statistically worse arterial cord blood pH (p=0.001, r=0.162) and base excess (p=0.05; r=0.094). Duration of DDI had no significant impact on the incidence of adverse neonatal outcome (p=0.123). Conclusion: Awareness of influence on DDI might contribute to expediting DDI, but duration of DDI showed no impact on the incidence of adverse neonatal outcome. Data were not adequate to suggest a recommendation for DDI time standards

Correlation of Cerebroplacental Ratio (CPR) With Adverse Perinatal Outcome in Singleton Pregnancies

Background/Aim: For many years clinical research has been concerned with doppler sonography as a non-invasive tool for intrauterine fetal status assessment. A new focus is now placed on the measurement of cerebroplacental index (CPR) as a predictor of fetal outcome. Our aim was to investigate the relationship between the cerebroplacental ratio (CPR), the delivery mode and the fetal outcome in singleton pregnancies. Patients and Methods: A retrospective cohort study of pregnancies in which doppler sonography of middle cerebral artery (MCA) and umbilical artery (UA) was conducted up to 9 weeks before delivery took place. Patients with pathological (CPR=1.0) and normal CPR (>1.0) were compared by umbilical cord pH, APGAR scores, birth weight, delivery week and delivery mode. Results: A total of 2,270 singleton pregnancies were included. The APGAR score for 1, 5 and 10 minutes and the gestational age at delivery were significantly lower in the group of patients with pathological CPR (p<0.001). Overall, 50% of the cohort had a cesarean section, the difference between the groups was statistically significant (p<0.001), with a higher amount of cesareans in the group of patients with pathological CPR. The multiple regression analysis showed a significantly improved pH of delivery when cesarean section (p<0.001), female sex of fetus (p=0.013) and higher CPR (p=0.035) were present. Conclusion: The measurement of CPR is an important, non-invasive predictive parameter and leads to the identification of a risk collective even in the non-selected patient population and thus probably to a reduction of perinatal morbidity

Profile and Outcome of Supraclavicular Metastases in Patients with Metastatic Breast Cancer: Discordance of Receptor Status Between Primary and Metastatic Site

Background: Breast cancer is a heterogenous and complex disease. A rare site of metastatic breast cancer disease is the neck. Data about supraclavicular metastases in patients with metastatic breast cancer are still lacking. Hence, our study aimed to analyze histological subtypes of supraclavicular metastases compared to the primary site. Materials and Methods: This was a retrospective hospital-based cohort study of patients with breast cancer who developed supraclavicular metastases. Diagnosis of supraclavicular metastases was confirmed by biopsy or diagnostic lymph node extirpation. Histological subtypes were analyzed and Kaplan-Meier estimates were calculated for overall survival. Results: A total of 20 patients were included in the analysis. The majority of the patients (12/20) had hormone receptor (HR)-positive/human epidermal growth factor receptor 2 (HER2)-negative supraclavicular metastases, disease in 3/20 patients was HR-positive/HER2-positive, HRnegative/HER2-positive in 1/20 patients and basal-like in 4/20 patients. Total discordance rates for estrogen receptor, progesterone receptor and HER2 between primary and metastatic tumors were 20.0%, 36.8% and 29.4%, respectively. The 5-year overall survival was 80%, whereas the 5-year survival after the onset of neck metastasis was 45%. Conclusion: As a rare site of metastatic breast cancer, supraclavicular metastases are associated with a worse median overall survival from their onset. The high rate of discordance of histological subtype stresses the necessity for biopsies in patients with supraclavicular metastasis

The Onset of Urinary Incontinence in Different Subgroups and its Relation to Menopausal Status: A Hospital-based Study

Background/Aim: Numerous risk factors have been reported to influence the development of urinary incontinence (UI). In this study, we took a closer look on the different forms of UI and tried to identify differences in regard to potential risk factors. Of special interest was the onset of UI symptoms and its relation to menopausal status. Patients and Methods: This was a hospital-based analysis of patients who presented with urinary incontinence in the outpatient ward of a tertiary hospital. The diagnosis of urinary incontinence was based on the subjective complaints of patients. Data concerning menopausal status, hormone replacement therapy, prior hysterectomy were assessed. Results: The mean age was 53.8 years in the SUI group, 62.7 years in the MUI group and 66.1 years in the UUI group, respectively (p<0.001). The proportion of patients with UUI was higher in the postmenopausal group, whereas the proportion of SUI was higher in the premenopausal group (p<0.001). The mean age in which complaints occurred was significantly lower in the SUI group (45.4 years) compared to the MUI (51.0 years) and UUI groups (54.7 years) (p<0.001). There was no correlation between menopausal status and onset of urinary incontinence (p=0.143). Conclusion: Additional anamnestic information help further characterize the different types of urinary incontinence that can lead to an optimization of treatment options. Younger age and premenopausal status were accompanied by milder forms of UI while menopausal status itself had no influence on the onset of UI symptoms indicating that age-related changes may lead to different types of incontinence

Preoperative biopsies as predictor for the necessity of inguinal lymph node surgery in squamous cell carcinoma of the vulva-a retrospective tertiary center analysis

Purpose Squamous cell carcinoma of the vulva (SQCV) is the fifth common cancer in women. Necessity of inguinal lymph node surgery depends on the depth of stromal invasion, inducing lymph node surgery, if depth of invasion is more than 1 mm. In this study we tested the prediction of stromal infiltration depth by measurements in preoperative biopsies. Methods We analyzed whether a different operative strategy in respect to lymph node surgery would have been chosen based on the pre- or postoperative depth of stromal invasion for each patient. Examination of infiltration depth in preoperative biopsies and surgical specimen were compared. Results In total 77 patients were included in this study. Of those 89.6% showed different depths of stromal invasion comparing the pre- and postoperative specimen. Within seventeen patients (22.1%) preoperative depth was 1 mm or less and a postoperative depth was > 1 mm. Conclusion We pointed, that only in 77.9% of the patients who should have undergo lymph node surgery based on the postoperative depth of infiltration underwent this procedure. Consequentially in 22.1% of the cases a second operation could not be prevented with a preoperative taken biopsy as indicator for the necessity of lymph node surgery

Comparison of Minimally Invasive Surgery and Abdominal Surgery Among Patients With Cervical Cancer

Background/Aim: The aim of this study was to evaluate the difference in clinical outcomes in patients with histologically confirmed cervical cancer of the uterus treated with either laparoscopy or laparotomy with curative intent between 2011 and 2017 at the Department of Gynecology and Obstetrics of University Hospital Cologne. Materials and Methods: This retrospective analysis included all patients who received surgical treatment with curative intent between January 2011 and December 2017 for stages IA1 to IIB cervical carcinoma. Patients receiving primary or secondary surgery after neoadjuvant chemotherapy were also included. Results: In total, 75 patients were included, of whom 34 patients underwent minimally invasive surgery and 41 underwent open surgery. Neoadjuvant chemotherapy was performed in 10 patients in the minimally-invasive group and in 14 patients in the laparotomy group. Statistically, no significant difference in overall survival (OS) was observed in both groups. Disease-free survival showed a significant difference in favor of the minimally invasive group. Conclusion: Minimally invasive surgical therapy for cervical cancer improves disease-free-survival. Prospective trials are needed to further confirm these results

Oral Misoprostol for the Induction of Labor: Comparison of Different Dosage Schemes With Respect to Maternal and Fetal Outcome in Patients Beyond 34 Weeks of Pregnancy

Background/Aim: Labor is induced in 1 out of 5 pregnancies. This is why we aimed to compare two different protocols of orally administered misoprostol for the induction of labor (IOL), with special regard to maternal and fetal outcome, delivery mode and duration. Patients and Methods: One hundred and twenty four patients with a medical indication for IOL were divided into two groups: Group A (n=63), which initially received 50 ,ug misoprostol escalated to 100 and, subsequently, to 200 ,ug every 4 h with a daily maximum of 600,ug, between 11/2007 and 01/2008; and Group B (n=61), which initially received 25 ,ug misoprostol followed by 100 ,ug every 4 h with a daily maximum of 300 ,ug, between 12/2009 and 04/2010. Results: The mean administration-delivery interval was significantly lower in Group A (19.0 h) compared to Group B (27.1 h, p<0.05). Overall caesarean section rate, average birth weight, APGAR score, umbilical cord pH and meconiumstained fluid rates were similar between both groups. Conclusion: A higher dosage protocol of orally administered misoprostol significantly reduces the mean induction-delivery interval without increasing the risk for an adverse maternal or fetal outcome

Doppler Indices and Notching Assessment of Uterine Artery Between the 19th and 22nd Week of Pregnancy in the Prediction of Pregnancy Outcome

Background/Aim: The aim of this study was to determine the value of Doppler indices and notching assessment of uterine artery between the 19th and 22nd week of gestation in the prediction of pregnancy outcome such as delivery mode, birth weight, Apgar score, afterbirth pH, fetal presentation, preeclampsia and fetal growth restriction in singleton pregnancy. Patients and Methods: This is a retrospective cohort study of Doppler ultrasound of the uterine arteries at 19-22 week of gestation in 1,472 women with singleton pregnancies. Results: Patients with bilateral high resistance-index (RI) and pulsatility-index (RI) or with the presence of a notch showed a significantly higher prevalence of small for gestational age (SGA) fetuses and intrauterine growth restriction (IUGR), low Apgar Scores at the 1st and the 5th min, high c-section rate, preterm birth, breech birth, placental insufficiency and placental abruption. The presence of a notch significantly increased the prevalence of severe preeclampsia, HELLP-syndrome and oligohydramnios. Also, patients with a bilateral uterine notching had a higher c-section rate along with higher prevalence of SGA and IUGR at screening time. Conclusion: Uterine artery Doppler waveform analysis as well as the assessment of the presence of a notch in the second trimester can be used as a screening method to identify women who will thereafter develop a severe adverse outcome

Occurrence of Residual Cancer Within Re-excisions After Subcutaneous Mastectomy of Invasive Breast Cancer and Ductal Carcinoma In Situ - A Retrospective Analysis

Background/Aim: Surgical margin status remains an important determinant for recurrence of invasive breast cancer and ductal carcinoma in situ. We compared the number of positive margins in initial histology with rates of residual tumor in re-excision specimens. Furthermore, we analysed cost-effectiveness of re-excisions. Patients and Methods: 101 patients treated with secondary surgery were included. The first group underwent breast conserving surgery and secondary mastectomy. The second group was primarily treated with subcutaneous mastectomy followed by secondary surgery. Results: Within the first group, 22.7% did not show residual tumor in the re-excision specimen. Of the second group, 54.3% had no residual tumor. Consequentially 45.7% needed a re-excision to achieve R0 status. Cost-effectiveness was determined as secondary endpoint. If a patient needs a secondary mastectomy the hospital gains 602,65(sic) in comparison to a primary breast conserving operation. Conclusion: In every second patient who had first received a subcutaneous mastectomy, no tumor could be detected in the secondary operation despite a previous R1 status
