Cytomegalovirus seronegativity rate in pregnant women and primary cytomegalovirus infection during pregnancy in rural Germany.

BACKGROUND: Congenital cytomegalovirus (CMV) infection is the most common congenital infection worldwide and one of the leading causes of congenital hearing loss in newborns. The aim of this study was to determine the seroprevalence rate for cytomegalovirus in pregnant women and the rate of CMV serological testing utilised during pregnancy in a rural region in Germany. METHODS: Retrospective data on the prevalence of CMV IgG and IgM antibodies were obtained from 3,800 women, identified in the study group of 19,511 pregnant women from outpatient settings whose samples were collected between 1 and 2014 and 30 April 2018. In addition, the serological CMV status in regards to various billing methods was further analyzed. RESULTS: Serological CMV tests were performed in 3,800 (19.5%) out of 19,511 pregnant women. 2,081 (54.8%) of these women were CMV seronegative. Among those, seroconversion rate of 0.37-1.42% was identified. A proportion of 2,710 (14.7%) of all 18,460 women with statutory health insurance made use of the CMV testing as an individual health service. CONCLUSIONS: The low uptake of CMV serological testing in the study population covered indicates low risk awareness among pregnant women and their healthcare professionals. Presented seronegativity rates and routine seroconversion rate, demonstrate importance to improve intervention strategy to prevent feto-maternal CMV transmission.

Enhanced S100B expression in T and B lymphocytes in spontaneous preterm birth and preeclampsia.

OBJECTIVES: S100B belongs to the family of danger signaling proteins. It is mainly expressed by glial-specific cells in the brain. However, S100B was also detected in other cell likewise immune cells. This molecule was suggested as biomarker for inflammation and fetal brain damage in spontaneous preterm birth (sPTB), preeclampsia (PE) and HELLP (hemolysis, elevated liver enzymes, and low platelet count). METHODS: The aim of our study was to determine the concentration of S100B in maternal and cord blood (CB) plasma and placenta supernatant as well as the expression of S100B in maternal and CB CD4+ T cells and CD19+ B cells in sPTB and patients delivering following PE/HELLP diagnosis compared to women delivering at term (TD). The S100B expression was further related to the birth weight in our study cohort. RESULTS: S100B concentration was enhanced in maternal and CB plasma of sPTB and PE/HELLP patients and positively correlated with interleukin-6 (IL-6) levels. Increased S100B was also confirmed in CB of small-for-gestational-age (SGA) infants. S100B expression in maternal blood was elevated in CD4+ T cells of PE/HELLP patients and patients who gave birth to SGA newborns as well as in CD19+ B cells of sPTB and PE/HELLP patients and patients with SGA babies. In CB, the expression of S100B was increased in CD19+ B cells of sPTB, PE/HELLP and SGA babies. CONCLUSIONS: Our results support the hypothesis that S100B expression is enhanced in inflammatory events associated with preterm birth and that S100B expression in immune cells is a relevant marker for inflammation during pregnancy complications.

Survival benefit of tamoxifen in male breast cancer: prospective cohort analysis.

BACKGROUND: Due to the lack of prospective data, current treatment of male breast cancer (MBC) is based on information obtained from retrospective analysis or by extrapolation from studies on female patients. In this prospectively enrolled cohort study, we retrospectively examined the survival effect of tamoxifen in MBC patients. METHODS: In this prospectively enrolled cohort study, 448 patients with MBC were treated between May 2009 and June 2018. The primary endpoint was disease-free survival (DFS). RESULTS: Between May 2009 and June 2018, 448 men with breast cancer were identified, with a median age at diagnosis of 69 years (range 27-96 years). The median follow-up was 39 months (range 3-89 months). Most tumours were larger than 20 mm; invasive ductal carcinoma was of no special histological type and with an intermediate grade of differentiation. Almost half of the men were diagnosed with positive axillary lymph nodes (43.5%). Hormone receptor (HR) positivity was observed in 98.4% of the patients. Notably, DFS among men who did not receive tamoxifen was significantly reduced as compared with those who underwent tamoxifen therapy (P = 0.002). The recurrence rate and mortality in the group of patients without and with tamoxifen treatment were 18.2% and 11.2%, respectively. The most common localisation of metastases was the bone. After adjustment for prognostic factors, we found that tamoxifen was found to reduce the recurrence rate by 68% (hazard ratio HR = 0.32; 95% confidence interval, CI: 0.14-0.74). CONCLUSIONS: Tamoxifen treatment was associated with improved DFS for MBC patients. CLINICAL TRIAL REGISTRATION: DRKS00009536.

Tamoxifen treatment for male breast cancer and risk of thromboembolism: prospective cohort analysis.

PURPOSE: Thromboembolism is a common adverse event in women treated with tamoxifen (TAM) for breast cancer. The risk in male breast cancer patients is poorly investigated. We aimed to examine the risk of thrombotic events after TAM in male breast cancer patients. PATIENTS AND METHODS: In this prospective cohort study, 448 patients treated between May 2009 and July 2017 for male breast cancer (BC) were assessed for eligibility. Patients with follow-up shorter than 6 months were excluded. The cumulative risk of thromboembolism was evaluated. RESULTS: The median follow-up was 47 months (range 6-101 months) with a median age of 69.4 years (range 27-89 years). Oestrogen receptor and progesterone receptor expression levels were observed in 98.3 and 94.9% of cases, respectively. During the follow-up period, thrombotic events were documented in 21 (11.9%) of 177 patients receiving TAM and in 1 (2.5%) of 41 patients who did not receive tamoxifen. The estimated incidence was 51.9 per 1000 person-years and 21.5 per 1000 person-years, respectively. Notably, the highest risk was identified in the first 18 months, where 81% of the observed thrombotic events occurred. Patients aged older than 71 years had a significantly increased risk of thrombotic event under TAM treatment than their younger counterparts (p = 0.033). History of thrombotic event, cardiovascular and liver disease, as well as additional adjuvant treatment were not associated with increased thrombotic risk. CONCLUSION: The risk of thrombotic event in men treated with TAM for breast cancer is markedly increased in the first 18 months of treatment, and should be considered during treatment decisions.

Post-Mastectomy Radiotherapy After Neoadjuvant Chemotherapy in Breast Cancer: A Pooled Retrospective Analysis of Three Prospective Randomized Trials.

BACKGROUND: The impact of locoregional radiotherapy (RT) after neoadjuvant chemotherapy (NACT) and mastectomy in breast cancer patients is currently unclear. Several publications have suggested that patients with a favorable response to NACT might not benefit from RT after mastectomy. METHODS: A retrospective analysis of three prospective randomized NACT trials was performed. Information on the use of RT was available for 817 breast cancer patients with non-inflammatory breast cancer who underwent mastectomy after NACT within the GeparTrio, GeparQuattro, and GeparQuinto-trials. RT was administered to 676 of these patients (82.7%). RESULTS: The 5-year cumulative incidence of locoregional recurrence (LRR) was 15.2% (95% confidence interval [CI] 9.0-22.8%) in patients treated without RT and 11.3% in patients treated with RT (95% CI 8.7-14.3%). In the multivariate analysis, RT was associated with a lower risk of LRR (hazard ratio 0.51, 95% CI 0.27-1.0; p = 0.05). This effect was shown especially in patients with cT3/4 tumors, as well as in patients who were cN+ before neoadjuvant therapy, including those who converted to ypN0 after neoadjuvant therapy. In the bivariate analysis, disease-free survival was significantly worse in patients who received RT, however this was not confirmed in the multivariate analysis. CONCLUSIONS: Our results suggest that RT reduces the LRR rates in breast cancer patients who receive a mastectomy after NACT without an improvement in DFS. Prospective randomized controlled trials such as the National Surgical Adjuvant Breast and Bowel Project B-51/RTOG 1304 trial will analyze whether RT has any benefit in patients who have a favorable response after NACT.

A randomized phase II study to determine the efficacy and tolerability of two doses of eribulin plus lapatinib in trastuzumab-pretreated patients with HER-2-positive metastatic breast cancer (E-VITA).

The E-VITA study evaluated the efficacy and tolerability of two schedules of eribulin and lapatinib in patients with trastuzumab-pretreated HER-2-positive metastatic breast cancer. This multicenter, open-label phase II trial, randomly assigned patients with trastuzumab-pretreated HER-2-positive metastatic breast cancer to lapatinib 1000 mg daily with eribulin 1.23 mg/m (equivalent to 1.4 mg/m eribulin mesylate) days 1+8 every 21 days (split-dose arm) or eribulin 1.76 mg/m (equivalent to 2.0 mg/m eribulin mesylate) day 1 every 21 days (3-weekly arm). Time to progression and tolerability were defined as primary end points; no sample size calculation for formal comparison of efficacy data has been performed. Secondary end points included objective response rate, clinical benefit rate, and overall survival. Overall, 43 patients of a planned number of 80 patients were recruited. At a median follow-up of 28.7 months, the median time to progression was 8.1 months [95% confidence interval (CI): 4.8-9.4] in the split-dose arm and 6.5 months (95% CI: 4.6-13.4) in the 3-weekly arm. Objective response rate was 52.4% (95% CI: 31.0-73.7) in the split-dose arm and 45.0% (95% CI: 23.2-66.8) in the 3-weekly arm, and clinical benefit rate was 71.4% (95% CI: 52.1-90.8) and 75.0% (95% CI: 56.0-94.0), respectively. Overall survival was also similar in both arms. The most frequent grade 3-4 adverse events were neutropenia (58.5%) and leukopenia (39.0%). The combination of eribulin and lapatinib showed an acceptable safety profile with less toxicity observed in the eribulin 1.23 mg/m day 1+8 group. This might be an alternative regimen when other treatment options are exhausted. Therefore, further clinical studies are warranted.

Oral etoposide for metastatic choriocarcinoma: a case report and review of guidelines.

BACKGROUND AND PURPOSE: Choriocarcinoma (CCA) is a rare form of malignant trophoblastic disease. Systemic polychemotherapy with etoposide, methotrexate, actinomycin D, cyclophosphamide, and vincristine (EMA/CO) is the mainstay of treatment for metastatic disease. Due to the rarity of the condition, however, the evidence basis for this management is small and other chemotherapy regimens may also be effective. The reported case presents anecdotal evidence of an effective etoposide monotherapy treatment. METHOD: CASE PRESENTATION: We report the case of a patient with gestational choriocarcinoma and pulmonary metastases initially treated with methotrexate. Due to local disease progression, she underwent hysterectomy and continued treatment with methotrexate. After pulmonary progression, she was switched to oral etoposide. RESULTS: After four cycles of etoposide monotherapy at a oral dosage of 100 mg d1-7, q28, the patient had no evidence of disease according to human chorionic gonadotropin serum levels and imaging studies. The treatment was well tolerated with World Health Organization (WHO) grade 2 alopecia and hot flushes as the most prominent side effects. The patient has achieved a sustained complete remission with a follow-up of 6 years. CONCLUSION: Oral etoposide may be an effective treatment alternative to EMA/CO in selected patients with oligometastatic CCA.

The impact of neuropsychiatric disease on fetal growth: a case-control study.

PURPOSE: To determine the impact of depression, epilepsy and drug abuse during pregnancy on delivery and fetal outcome. Due to the worldwide increasing prevalence of neurological and psychiatric diseases and drug abuse, the number of affected pregnant women is increasing. METHODS: A large-scale retrospective case-control analysis of pregnancies affected by depression, epilepsy or drug abuse with and without medication was conducted in two German perinatal centres between 2013 and 2017. The case group consisted of 706 pregnant women who had a diagnosis of depression, epilepsy or drug abuse vs. 12,574 pregnant women without neuropsychiatric diagnosis (control group). The analysis included the rate of intrauterine growth restriction, birth weight and length, neonatal head circumference. RESULTS: Significant differences in the subgroups were found in the parameters intrauterine growth restriction, birth weight, length and head circumference. Women with epilepsy were affected less often than women with depression and substance abuse. Major differences were found in the group of women with substance abuse. Negative associations were found within the non-pharmacologically managed disease group itself compared to women exposed to medication. CONCLUSION: The present results demonstrated a negative association between maternal neurological or psychiatric disease and pregnancy outcome in the examined parameters. However, the non-pharmacologically treated maternal disease was identified as a risk factor itself.

Does ultrasound-guided intervention during repeat cesarean sections improve uterine scar architecture and reduce the number of scars? A prospective controlled clinical intervention trial.

Purpose To evaluate whether intraoperative ultrasound-guided detection and resection of the uterine scar during repeat/second cesarean can reduce the number of scars and improve uterine scar architecture. Materials and methods A prospective controlled clinical intervention trial was performed with the following groups: control group 1 (CS1-G): first cesarean; control group 2 (CS2-G): second cesarean utilizing the usual procedure and intervention group (Int-G): repeat/second cesarean with intervention. Transvaginal ultrasound scans were performed 6-9 months after each cesarean. Both primary (double scarring rate) and secondary outcomes [deficiency ratio=d/(b+d)] were analyzed. The deficiency ratio describes the thinning of the remaining myometrium (d=residual myometrial thickness) over the "apparent" defect (b=scar depth). Results In total, 124 of the 156 recruited women were examined, eight were excluded from analysis. The double scarring rate decreased from 42.9% (12/28) in CS2-G to 7.1% (2/28) in the Int-G [difference: 35.8%; 95% confidence interval (CI) (13.2, 54.5); P=0.002]. Two-way analysis of variance (ANOVA) revealed a significant difference between CS2-G and the Int-G in the deficiency ratio adjusted for elective/primary cesareans, with thicker remaining myometrium over the scar defect in the Int-G [difference: -0.24; 95% CI (-0.34, -0.15); P<0.001]. Conclusion Ultrasound-guided resection of the uterine scar area during repeat cesareans reduces the scarring rate and improves thickness of the remaining myometrium as detected by ultrasonography 6-9 months postoperatively.

Management of small T1a/b breast cancer by tumor subtype.

BACKGROUND: The treatment of patients with small (T1a/b) breast cancer is based on retrospective analysis. The influence of intrinsic tumor subtypes on patients' outcome and treatment decision remains unclear. PATIENTS AND METHODS: This is a prospective cohort register study including 1008 patients with small T1a/b breast cancer treated between 2003 and 2011. Tumors were grouped by biological characteristics into four different subtypes: luminal A, luminal B, human epidermal growth factor receptor 2 (HER2)-enriched, and triple-negative breast cancer (TNBC). RESULTS: The median follow-up time was 6.5 years. From 919 eligible patients, 408 (44.4%) were classified as luminal A, 246 (26.8%) as luminal B, 183 (19.9%) as HER2 enriched, and 82 (8.9%) as TNBC. A total of 305 (34.2%) patients were treated with systemic therapy. Patients receiving systemic therapy were significantly younger and had lymph node metastasis, higher tumor grade, negative HR, and positive HER2 status. Patients with luminal A tumors demonstrated the best survival rate which improved with systemic therapy. The survival rate of patients with luminal B cancer, HER2-enriched tumors, and TNBC improved by addition of systemic treatment. The effect of systemic treatment was significant in luminal B (p = 0.040) and HER2 overexpressing tumors (p = 0.016). The treatment effect of systemic therapy in HER2-enriched tumors remained significant even after adjustment of other prognostic factors (HR 0.43, CI 0.19-0.98; p = 0.047). Notably, tumor size was not associated with patients' survival and treatment decision. CONCLUSION: The treatment decision of small breast cancer should be made by biological subtype and not by tumor size or lymph node status.

Efficacy and safety of nab-paclitaxel 125 mg/m2 and nab-paclitaxel 150 mg/m2 compared to paclitaxel in early high-risk breast cancer. Results from the neoadjuvant randomized GeparSepto study (GBG 69).

PURPOSE: The GeparSepto study demonstrated that the use of nab-paclitaxel instead of paclitaxel prior to anthracycline-based chemotherapy could lead to a significantly increased pCR rate, especially in the triple negative subpopulation. We report efficacy and safety for patients treated with two different doses of nab-paclitaxel in comparison to weekly solvent-formulated paclitaxel. METHODS: Patients were treated for 12 weeks with either intravenous nab-paclitaxel 150 mg/m2 (nP150) weekly, after study amendment 125 mg/m2 (nP125) weekly or solvent-based paclitaxel 80 mg/m2 (P80) weekly followed by epirubicin 90 mg/m2 and cyclophosphamide 600 mg/m2 on day 1 for four 3-week cycles. RESULTS: 229 patients received nP150, 377 nP125. Baseline characteristics were fairly balanced between these two sequential cohorts as well as compared to 601 patients receiving P80 except for hormone receptor status, HER2 status, and Ki67. Taxane treatment was discontinued in 26.8% (nP150), 16.6% (nP125), and 13.3% of (P80) patients, respectively. Median relative total dose intensity (mRTDI) based on 125 mg/m2 for nP was 103% with nP150, 95% with nP125, 99% with P80 before and 98% with P80 after the amendment. PSN grade 3-4 was observed in 14.5% of patients with nP150, 8.1% of patients with nP125 (p = 0.018), and 2.7% of patients with P80. Overall pCR before the amendment was 33.6% after nP150 and 23.5% after P80 (OR 1.65 [95% CI 1.10-2.50]; p = 0.022); pCR after the amendment was 41.4% after nP125, and 32.4% after P80 (1.48 [95% CI 1.10-1.99]; p = 0.013). CONCLUSIONS: Nab-paclitaxel 125 mg/m2 was associated with a better safety profile and compliance without compromising the efficacy compared to nab-paclitaxel 150 mg/m2.

Adjuvant hysterectomy after radiochemotherapy for locally advanced cervical cancer.

BACKGROUND: External beam radiation therapy (EBRT) with concomitant chemotherapy (cCT) (=RCT) plus intracavitary (±interstitial) brachytherapy (iBT) is standard of care for advanced cervical cancer. The aim of this study was to evaluate morbidity and survival outcome of simple adjuvant hysterectomy (AH) after EBRT/cCT and to compare it with the standard treatment. PATIENTS AND METHODS: Patients with FIGO stage III cervical cancer were treated with EBRT/cCT and then divided in two groups: group 1 was further treated with standard intracavitary/interstitial BT, while group 2 underwent AH. RESULTS: From 881 women with cervical cancer, 248 were eligible for analysis: 161 received iBT and 87 underwent AH. The median follow-up of the study was 53 months. Clinical and pathological characteristics were well balanced in the two groups. After EBRT/cCT, complete clinical response was observed in 121 (48.8%) of 246 patients. Clinical complete response was observed in 81 (50.3%) of 161 patients in group 1. At 6 weeks after EBRT/cCT, 40 (46.0%) of 87 patients in the surgery group had pathological complete response. Intra- and postoperative complications were observed in 10 (11.5%) of 87 cases. The rates of locoregional recurrence and metastasis were similar in both groups. Progression-free (PFS) and disease-specific overall survival (DOS) for these patients were similar between the control and surgery group. Interestingly, PFS and DOS were significantly improved by AH for the patients with residual tumor. CONCLUSION: AH could improve survival in patients with residual disease after RCT and is characterized by a low complication rate.

Management of elderly women with endometrial cancer.

BACKGROUND: Elderly women with endometrial cancer receive less therapy in comparison with their younger counterparts. The exact reason(s) for this treatment strategy remains unclear. PATIENTS AND METHODS: We performed a multicenter, retrospective registry-based study of 1550 patients with endometrial cancer. The outcome measure was the reason for not performing the indicated treatment. RESULTS: Median follow-up was 76.8months. A total of 1550 women were eligible for analysis: 353 (22.7%) were younger than 60years, 521 (33.6%) 61-70years, 515 (33.2%) 71-80years, and 161 (10.4%) were aged 81years old and older. Elderly women were more likely to have non-endometrioid, undifferentiated endometrial cancer at an advanced stage. Patients younger than 60years were more likely to receive lymphadenectomy, brachytherapy, external-beam radiotherapy (EBRT) and systemic therapy compared with the group of patients aged older than 70years. We investigated the reason why elderly women were undertreated. The rate of indicated therapies that were not recommended by the physicians proportionally increased with an increase in patient age. Interestingly, the rate of contraindications because of performance status and/or medical disease also increased proportionally with increasing patient age. Notably, in the groups of patients older than 70years, patient refusal was a very uncommon reason for failure to perform the indicated therapy. CONCLUSIONS: Elderly women with EC are more likely undertreated because the therapy was not recommended by the physicians based on performance status and medical diseases rather than patient refusal.

Perinatal and maternal outcomes at term in low-risk pregnancies according to NICE criteria: comparison between a tertiary obstetrical hospital and midwife-attended units.

PURPOSE: The aim of this study was to evaluate the perinatal and maternal outcomes at term at a single tertiary, university hospital in women with low-risk pregnancies. PATIENTS AND METHODS: We performed a retrospective cohort study of women with low-risk pregnancies, who delivered at University Women's Hospital Magdeburg between January 2010 and December 2014. Data were compared with data published by Brocklehurst et al. 2011. RESULTS: Of the 6052 women investigated, 2014 were classified as low risk according to the NICE criteria and were eligible for analysis. In 94.8%, a spontaneous vertex birth was observed. There were only 2 (0.1%) perinatal complications and 52 (2.5%) maternal complications. Ventouse delivery, forceps delivery, and caesarean sections were performed in 2.5, 1, and 3.1% of the cases, respectively. Episiotomy was performed in 37.7% of women. The third and fourth degree perineal trauma were observed in 0.3% of births investigated. Complications during the third stage of labour and blood transfusions were observed in 0.25 and 0.2%, respectively. In comparison with the births at home, we had lower rate of fetal complications for nulliparous women, but not for multiparous women, lower rate for blood transfusions, third and fourth degree perineal trauma and forceps delivery, and higher rate of spontaneous vertex birth, epidural analgesia, and episiotomy. The rate of vacuum extractions and caesarean sections were similar between both the places of birth. CONCLUSIONS: The tertiary-level obstetric unit is safe place of birth for women with low-risk pregnancies.

Congenital cytomegalovirus infection in Central Germany: an underestimated risk.

PURPOSE: This is the first study to determine the cytomegalovirus (CMV) seronegativity rate for women of childbearing age in Saxony-Anhalt and to determine the prevalence of clinically relevant congenital CMV (cCMV) infection in Central Germany, because there are no valid data available. METHODS: The retrospective study was undertaken between January 2005 and December 2015. For the first time in Germany, the following seven data sources were used to analyze the prevalence of clinically relevant cCMV infection and the rate of CMV seronegative women of childbearing age: CMV Screening in maternity unit, University Women's Hospital, Social Paediatrics Centre (SPC), Malformation Monitoring Centre (MMC), Newborn Hearing Screening (NHS), Neonatal Intensive Care Unit (NICU), and In-house Doctor Department. Key parameters were anti-CMV IgG and IgM, CMV PCR of urine, and clinically relevant symptoms caused by CMV. RESULTS: Between 46 and 52% of women of childbearing age were CMV seronegative. The prevalence of clinically relevant cCMV infection was between 0.008 and 0.04%. CONCLUSIONS: The CMV seronegativity rate of women of childbearing age was confirmed to be in the middle range of estimated data from other sources in Germany. Data from the NICU, SPC, NHS, and MMC show the prevalence of clinically relevant cCMV infection. The risk of all cCMV infections is underestimated. Thus, the true prevalence of clinically relevant and subclinical cCMV infections is >0.04%.

Should the hyperechogenic halo around malignant breast lesions be included in the measurement of tumor size?

The estimation of tumor size is important for treatment strategies of breast cancer. The hyperechogenic zone around breast cancer is a recognized criterion for malignancy, but its impact on preoperative tumor size estimations has been poorly investigated. Data of prospectively maintained database of 513 patients with primary breast tumors were analyzed retrospectively. A total of 196 patients with complete datasets including preoperative ultrasound (US) were eligible for analysis. The median age of the patients was 58.5 years (range 33-87). With all of the 196 patients, US has been performed. In 170 of 196 (86.7 %) cases, an echogenic halo was detected. We use two ways to measure tumor size with US: without (US-0) and with (US-1) echogenic halo. Mammography (MG) was used as standard. Tumor size measured by US and MG was compared with the actual histopathological (HP) tumor size. Mean differences between the sizing obtained by US-0, US-1, and MG and the HP sizing were -6.5, -1.5, and -1.8 mm, respectively. All three methods tend to underestimate the tumor size. The US-1 measurement was the closest to the HP size in comparison to the MG and US-0 measurements and the match was higher in tumors <2 cm. The estimated Pearson correlation coefficients (r) were 0.72, 0.68, and 0.61 for US-1, US-0, and MG, respectively. Moreover, the predictive value of US-1 regarding tumor size was not influenced by histological type and grade of the tumor, receptor status, and presence of intraductal component. Estimation of tumor size by US should include the hyperechogenic zone around the tumor.

JEG-3 Trophoblast Cells Producing Human Chorionic Gonadotropin Promote Conversion of Human CD4+FOXP3- T Cells into CD4+FOXP3+ Regulatory T Cells and Foster T Cell Suppressive Activity.

The pregnancy hormone human Chorionic Gonadotropin (hCG) reportedly modulates innate and adaptive immune responses and contributes thereby to fetal survival. More precisely, hCG has been shown to support human Treg cell homing into the fetal-maternal interface and enhance number and function of Treg cells in murine pregnancy. Here, we aimed to study whether hCG and hCG-producing human trophoblast cell lines induce Treg cells from CD4+FOXP3- T cells and promote T cell suppressive activity. CD4+FOXP3- T cells were isolated from peripheral blood of normal pregnant women and cultured in the presence of hCG-producing (JEG-3, HTR-8) and non-producing (SWAN-71) cell lines. To confirm the participation of hCG in Treg cell conversion, the experiments were performed in the presence of anti-hCG and additional experiments were run with recombinant or urine-purified hCG. After culture the number of CD4+FOXP3+ Treg cells as well as the suppressive capacity of total T cells was assessed. hCG-producing JEG-3 cells as well as recombinant and urine-purified hCG induced CD4+FOXP3+ Treg cells from CD4+FOXP3- T cells. Blockage of hCG impaired Treg cell induction. Moreover, hCG-producing JEG-3 cells increased suppressive activity of CD4+FOXP3- T cells through an antigen-independent pathway. Our results propose another mechanism through which hCG modulates the female immune system during pregnancy in favor of the fetus.

Peritoneal closure during laparoscopic supracervical hysterectomy.

OBJECTIVE: Our goal was to compare postoperative pain and analgesic requirements regarding closure and non-closure of the peritoneum in women undergoing laparoscopic supracervical hysterectomy (LSH). STUDY DESIGN: A prospective cohort study was designed to investigate the impact of peritoneal closure for LSH. Postoperative pain was measured by a visual analogue scale (VAS) and analgesic requirements were assessed. Intra- and postoperative complications and operative time were recorded. RESULTS: A total of 104 patients were enrolled. Fifty-two (50 %) women underwent a LSH with peritoneal closure and 52 (50 %) underwent LSH without closure. The baseline characteristics were well balanced between the groups except for age; women undergoing LSH without peritoneal closure were significantly younger (p < 0.008, t test). The median operative time was 53 (26-105) minutes for LSH with peritoneal closure and 44 (24-83) minutes for LSH without peritoneal closure, a median reduction of 9 minutes (p = 0.007). No differences were found in uterine weight, intra- and post-operative complications, median haemoglobin drop or time in hospital when contrasting both groups. Both groups had similar VAS-pain scores and needed similar analgesic therapies. CONCLUSIONS: The peritoneal closure at LSH provides no short-term postoperative advantages over a non-closure approach, and it prolongs the operative time and anaesthetic exposure. Our data suggest that peritoneal closure is not necessary in LSH.

Moderate level of HER2 expression and its prognostic significance in breast cancer with intermediate grade.

Overexpression of human epidermal growth factor receptor 2 (HER2) is an important prognostic and predictive marker of response to anti-HER2 therapy in breast cancer. Our goal was to analyze the prognostic significance of moderate expression of HER2 in breast cancer with intermediate differentiation grade. We performed a multicenter retrospective register study of 8494 patients with primary non-metastatic breast cancer admitted between 2000 and 2011 to eight Clinics in Saxony-Anhalt, federal state of Germany. Patients were divided into three groups according to their HER2 score: 4073 were classified as HER2 negative (HER2 0 and 1+), 822 HER2 moderate (HER2 2+/HER2), and 1238 HER2 positive (HER2 3+ or HER2 2+/HER2+). HER2-positive cases were excluded from analysis. Tumors with moderate HER2 (HER2 2+) expression demonstrated an aggressive behavior and worse patient survival compared with HER2 0 and 1+ status. HER2 2+ status was associated with shorter median overall survival (OS) (P < 0.0001) in breast cancer patients with an intermediate grade of differentiation. Comparing low-grade and high-grade tumors, HER2 moderate expression did not significantly influence patient survival. In multivariate analysis after adjustment for other prognostic factors HER2 2+ status remained an unfavorable prognostic factor for OS (HR 1.224, 95 % CI 1.059-1.415, P = 0.006) in breast cancer patients with an intermediate grade of differentiation. HER2 2+ status is an unfavorable prognostic factor regarding the OS of breast cancer patients with intermediate grade of differentiation and could be used to identify patients, who may benefit from adjuvant therapy.

Outcome after neoadjuvant chemotherapy in young breast cancer patients: a pooled analysis of individual patient data from eight prospectively randomized controlled trials.

Young women with breast cancer (BC) have a worse survival partly due to more aggressive tumor characteristics; however, their response to chemotherapy seems better. We investigated to what extent the prognostic factor pathological complete remission (pCR) after neoadjuvant chemotherapy is applicable to young women. 8949 patients with primary BC and follow-up from eight German neoadjuvant trials were included. A subgroup of 1453 patients <40 years was compared with women aged 40-49 and ≥50 years regarding pCR (ypT0 ypN0), as well as disease free survival (DFS), local recurrence free survival (LRFS), distant disease free survival (DDFS), and overall survival (OS) overall, according to pCR status and subtypes defined by hormone-receptor (HR) status and HER2. pCR was strongly associated with age without a clear age cut-off. The pCR rate was significantly higher in the young compared with other age groups (20.9 vs. 17.7 vs. 13.7 %; p < 0.001). This difference was confined to triple-negative breast cancer (TNBC) and HR +/HER2-. DFS, DDFS, LRFS, and OS were significantly worse for young women. Age was independently prognostic for survival in HR +/HER2-, with women <40 years without pCR having a worse DFS compared to their counterparts with pCR. Young women are more likely to achieve pCR after neoadjuvant chemotherapy, especially in HR +/HER2- and TNBC. Age is not an important prognostic factor in TNBC and HR-/HER2 + but is in HR +/HER2-. Young women with a luminal-like BC seem to benefit more from neoadjuvant chemotherapy than older women, which needs to be taken into account.
