Care needs and self-induced measures of women with postpartum pelvic floor disorder- Results of a social media-based survey of 2930 women.

INTRODUCTION: Pelvic floor disorders (PFD) occur in about 40% of women after delivery. Less is known about the intervention and care needs of women with postpartum PFD. The aim of this analysis was to analyze care needs and self-initiated measures to strengthen the pelvic floor in postpartum women in relation to incontinence and sexual dysfunction. Furthermore, influencing factors for self-initiated measures were evaluated. PATIENTS AND METHODS: An anonymous online survey (via LimeSurvey) was conducted between September and October 2022 and distributed via social media (Instagram and Facebook). The survey explicitly addressed mothers with and without pelvic floor disorders up to 5 years postpartum (inclusion criteria). Validated instruments were employed to assess incontinence (ICIQ-SF) and sexual functioning (PISQ-IR: Condition Impact). The questions on the use of services and preventive measures, as well as on the interaction with a gynecologist, were based on self-developed items. RESULTS: In total, 49.4% of the participants of the survey showed symptoms of urinary incontinence (UI). Furthermore, only 40.3% (n = 241) of women were actively asked by their gynecologists for the occurrence of UI or PFD among those who suffered from PFD. Overall, 79.3% of the participants of the survey with UI underwent measures to deal with the complaints. The ICIQ-SF Score was significantly associated with all self-induced measures. High School diplomas and academic degrees were associated with the use of love balls (p < 0.05). CONCLUSION: The results of the study show the unmet needs of postpartum women. PFD should be addressed more frequently in the outpatient setting. Furthermore, more systematic information about the treatment of PFD could help to address unmet information needs and improve interventions.

Platelet-rich plasma (PRP) in oncological patients: long-term oncological outcome analysis of the treatment of subcutaneous venous access device scars in 89 breast cancer patients.

PURPOSE: Platelet-rich plasma (PRP) is widely used product, and meta-analyses showed this product to be beneficial when applied to a wound area. This study group has already demonstrated increased patient satisfaction and lower complication rates in breast cancer patients who received PRP after removal of their subcutaneous venous access device. This work is a follow-up analysis focusing on oncologic safety. Currently, there is no long-term data on the use of PRP products in cancer patients available yet. METHODS: Between the years 2012-2016, venous access device removal was supported with the application of Arthrex ACP® (Autologous Conditioned Plasma)-a PRP product to improve the wound-healing process. All surgeries were performed in the breast cancer center of the municipal hospital of Cologne, Holweide, Germany. 35 patients received an application of Arthrex ACP® after port removal compared to the control group of 54 patients. Endpoints were local recurrence-free, distant recurrence-free as well as overall survival. RESULTS: Median follow-up was 45 months. No (0) adverse events were shown for cancer recurrence within the subcutaneous venous access device scar area. Thus, there seems to be no local oncogenic potential of the PRP product. All other endpoints as well as any-cause death numerically favor PRP use. CONCLUSION: PRP products such as Arthrex ACP® seem to be oncological inert when applied after removal of subcutaneous access devices. This is the first study providing long-term data about overall survival, distant recurrence-free and local recurrence-free survival after applying PRP in high-risk cancer patients.

Intraoperative central nipple biopsy in nipple-sparing mastectomy- A retrospective analysis of 211 patients.

Subcutaneous nipple sparing mastectomies (NSM) are an important tool in modern oncoplastic surgery. Especially when an immediate implant-based reconstruction (IBR) is desired, clean margins are of the utmost importance. Central nipple biopsies during surgery serve two main purposes. Most importantly, it is hypothesized that intraoperative pathological evaluation of this biopsy may increase clean margin resection rates. In addition, a general recurrence risk reduction may occur due to the elimination of glandular and ductal components within the nipple. This analysis is a single center, multi-surgeon, retrospective, head to head analysis. Starting in March 2015, intraoperative central nipple biopsy in NSMs with IBR was introduced at the Municipal Breast Cancer Centre Cologne, Holweide, Germany. This trial retrospectively evaluates global complication rates, clean margin status and local recurrence rates for cohort 1 (NSM/no nipple biopsy, n = 103) vs. cohort 2 (NSM with nipple biopsy, n = 108) Median follow-up was 15 months. All implant-based reconstruction procedures used an epipectoral implant pocket. Cohorts were comparable. Global complication rates slightly favored the nipple biopsy cohort with respects to implant loss rate. An involved central nipple biopsy was found in 4.6% (n = 5/108) of the performed NSM procedures leading to the immediate removal of the nipple areola complex. All positive retro-areolar biopsies correlated with a positive nipple biopsy. However, in n = 1 case we found DCIS discontinual proliferation with an involved nipple biopsy, without a correlating positive retro-areolar biopsy (ie, 1 false-negative case was prevented). For the 15 month follow-up, there was no case of local recurrence within nipple areola complex for both cohorts. With this retrospective head to head analysis of 211 patients, it was shown that the central nipple biopsy correlates well with the retro-areolar biopsy. There may be a reduction in false negative rates. The procedure is safe to use and should be offered to NSM patients.

Tumour-infiltrating neutrophils counteract anti-VEGF therapy in metastatic colorectal cancer.

BACKGROUND: Immune infiltration is implicated in the development of acquired resistance to anti-angiogenic cancer therapy. We therefore investigated the correlation between neutrophil infiltration in metastasis of colorectal cancer (CRC) patients and survival after treatment with bevacizumab. Our study identifies CD177+ tumour neutrophil infiltration as an adverse prognostic factor for bevacizumab treatment. We further demonstrate that a novel anti-VEGF/anti-Ang2 compound (BI-880) can overcome resistance to VEGF inhibition in experimental tumour models. METHODS: A total of 85 metastatic CRC patients were stratified into cohorts that had either received chemotherapy alone (n = 39) or combined with bevacizumab (n = 46). Tumour CD177+ neutrophil infiltration was correlated to clinical outcome. The impact of neutrophil infiltration on anti-VEGF or anti-VEGF/anti-Ang2 therapy was studied in both xenograft and syngeneic tumour models by immunohistochemistry. RESULTS: The survival of bevacizumab-treated CRC patients in the presence of CD177+ infiltrates was significantly reduced compared to patients harbouring CD177- metastases. BI-880 treatment reduced the development of hypoxia associated with bevacizumab treatment and improved vascular normalisation in xenografts. Furthermore, neutrophil depletion or BI-880 treatment restored treatment sensitivity in a syngeneic tumour model of anti-VEGF resistance. CONCLUSIONS: Our findings implicate CD177 as a biomarker for bevacizumab and suggest VEGF/Ang2 inhibition as a strategy to overcome neutrophil associated resistance to anti-angiogenic treatment.

The impact of EndoPredict ® on decision making with increasing oncological work experience: can overtreatment be avoided?

BACKGROUND: Estimating distant recurrence risk in women with estrogen receptor-positive, human epidermal growth factor receptor 2 (HER2)-negative early breast cancer is still challenging. EndoPredict® is a gene expression-based test predicting the likelihood of recurrent disease. We analyzed the difference in oncological decision making with and without the knowledge of gene expression tests. PATIENTS AND METHODS: This is a retrospective analysis including patients diagnosed with hormone-receptor positive, Her2 negative breast cancer between 2011 and 2015 at the Municipal Breast Cancer Centre Cologne, Germany. All patients received an evaluation by EndoPredict®. An oncological tumor board (TB) with knowledge of these results served as a baseline (control group). This baseline was compared to the treatment decision (adjuvant chemotherapy yes vs. no) made by oncologists with different experience levels (less than 5 years, between 5 and 15 years, and more than 15 years) who were not provided the EndoPredict® scores. All clinicians had access to clinical as well to histopathological data. RESULTS: There was no significant difference between control group and the oncologists with different experience levels concerning a chemotherapy indication. A trend could be shown in the subgroup of nodal negative patients between the treatment recommendation and physicians with more than 15 years of experience (p = 0.088). A further trend could be demonstrated in the subgroup of patients with a low Ki67 index (≤ 14%) (p = 0.063) between physician with 5-10 years of clinical experience and official treatment recommendation. CONCLUSION: It seems that inexperienced physicians may profit from the use of EndoPredict® to avoid an overtreatment. In nodal negative patients and patients with a low Ki67 index, undertreatment can be avoided with the use of EndoPredict® (borderline significance). Further prospective studies with larger study cohorts are needed to further validate this tool.

Influence of androgen levels on conception probability in patients undergoing fertility treatment: a retrospective cohort study.

PURPOSE: Primary and secondary sterility have become an issue of increasing importance due to demographic and social changes in society. Data regarding the association between female androgen levels and the probability of successful conception after fertility treatment are sparse and contradictive. This study was designed to assess this clinical question. METHODS: In this retrospective single-center cohort study concentrations of androgens androstenedione, dehydroepiandrosteronsulfat (DHEAS) and testosterone (ng/ml) were investigated in the serum of patients presenting for sterility at the department of reproductive medicine of Saarland University hospital Homburg between January 2015 and December 2017. Androgen levels were correlated with reproductive outcomes. Statistical analysis was performed with the aid of SPSS version 24. Significance for conception rates in dependence of androgen concentration was assessed using Kruskal-Wallis test (significance was estimated with p < 0.05). RESULTS: The laboratory values of a total of 301 patients were examined (64% primary, 36% secondary sterility). Median age at first visit at the fertility department was 32.7 years (range 20-47 years). 64 pregnancies were observed during the study period (conception rate 21.3%). 23 out of 301 patients (7.6%) suffered from hypoandrogenaemia, 248 (82.4%) had normal androgen levels and 30 (10%) showed hyperandrogenaemia (p = 0.25). Regarding patients in whom fertility treatment was successful 3 (4.7%) showed hypoandrogenaemia, 54 (84.4%) were normoandrogenaemic and 7 (10.9%) had hyperandrogenaemia (p = 0.40 Kruskal-Wallis test). CONCLUSIONS: We found no association between female androgen levels and sterility and reproductive outcomes.

Emergency department use during pregnancy: a prospective observational study in a single center institution.

PURPOSE: Gynecologists working in emergency department services in hospitals lately have the impression that the number of pregnant women who present themselves because of anxiety or uncertainty is increasing. Hence, the aim of this study was to assess reasons of pregnant women for presenting themselves to an emergency department. Of special interest was how far a diagnosis could be confirmed for the symptoms pregnant women complained about. METHODS: This is a prospective questionnaire-based study conducted between April 2015 and April 2016 in the Department of Gynecology and Obstetrics of the University Hospital of Cologne. The questionnaire was placed in the waiting area of the emergency department service for pregnant women. Pregnant patients were included with a gestational age of above 20 weeks of gestation. RESULTS: 331 patients were enrolled in this study. The most frequent reason for emergency department use was "pain" in 28.3% and cervical insufficiency in 19.7% of all cases. 45.6% (n = 151) of the patients had a recommendation of an outpatient practice for presentation to emergency department service. 36.3% (n = 120) of all patients were admitted to hospital for further treatment, 58.6% (n = 194) could be released from hospital. 3.3% (n = 11) of all patients rejected recommended further treatment in hospital. A trend was demonstrated concerning former abortion and hospital admission (p = 0.062). CONCLUSIONS: The high amount of patients making nonurgent use of emergency department services indicates potential uncertainty in interpretation of symptoms. Patients with former abortion history were admitted more often to hospital, and therefore need special attention during pregnancy.

Instrument usage in laparoscopic gynecologic surgery: a prospective clinical trial.

PURPOSE: To evaluate instrumental usage in laparoscopic gynecological surgeries and to develop key timesets of a laparoscopic operation, which allows categorization of the operation time into different sections. METHODS: In this prospective clinical observational study, frequency of instrument usage, time for instrument switches, and instrument utilization time were recorded in a standardized manner for laparoscopic surgeries in 103 endoscopic surgeries. RESULTS: A standard equipment (including atraumatic grasping forceps, irrigation and suction device, bipolar clamp, and laparoscopic scissors) was used for nearly all interventions. Bipolar clamps and scissors were changed most frequently. The tool used for the longest amount of time was the atraumatic grasping forceps. Laparoscopic instruments were switched 51 times per surgery (range 2-250 times). One instrument switch lasted for a median of 0.13 min (0.08-1.2 min). Median time for instrument switch for a single surgery added up to 6.83 min. Instrument switches required 10.5% of the overall operation time. CONCLUSION: We analyzed the current instrument usage in laparoscopic gynecological surgeries. The results of our standardized investigation suggest ways to reduce the time required for surgery and provide starting points for the standardization of the work routine.

The number of removed lymph nodes by inguinofemoral lymphadenectomy: impact on recurrence rates in patients with vulva carcinoma.

OBJECTIVE: Inguinal lymph node (LN) metastasis is a crucial prognostic factor in vulva carcinoma. The aim of this study was to determine the prognostic value of the number of resected LNs in patients with vulvar carcinoma on recurrence rates. METHODS: This retrospective study includes patients with vulvar squamous cell carcinoma who underwent inguinofemoral lymphadenectomy (IFL) between 1998 and 2011. Dissected groins were stratified by the number of removed lymph nodes (<6 LNs versus ≥6 LNs) or inguinal LN metastasis (pN- versus pN+) and analyzed according to groin, local and distance recurrence rates. RESULTS: In total 45 patients were identified and 79 groins were eligible for this analysis. 11 patients underwent ipsilateral IFL and 34 bilateral IFL. The median age was 58 years (range 31-80). The median tumor size was 2 cm (range 0.1-7.9). A median of 8 (range 0-19) LNs were resected per groin. Overall in 11 groins LN metastases were found. Groin recurrences occurred in four patients, local recurrence in six patients and distant metastasis in one patient. We did not observe any significant improvement in groin recurrence rates, local recurrence rates and distant recurrence rates if more than six LNs were removed per groin. Notably, patients with LN metastasis did not show higher recurrence rates compared to unaffected LNs. CONCLUSION: In this cohort we demonstrated that resection of more than six LNs per groin does not improve the recurrence rates in patients with carcinoma of the vulva. Further prospective studies with more individuals are needed to evaluate the role of resected LNs in vulvar carcinoma.

Cervical screening program and the psychological impact of an abnormal Pap smear: a self-assessment questionnaire study of 590 patients.

PURPOSE: Invasive cervical cancer is today the fourth most common cancer of women in western civilization. Screening programs have led to a continuously decrease. Nevertheless, both screening and a positive test result are known to be associated with a negative psychological impact. Screening programs in European countries differ and thus psychological impact might as well. The aim of this study was to evaluate the psychological impact of women with an abnormal Pap smear in a German cohort. METHODS: Between July 2013 and May 2014, a self-assessment questionnaire was distributed to 595 patients that were referred to a special clinic for cervical dysplasia for further evaluation of an abnormal Pap smear. Patients were recruited in five different centers. RESULTS: Most patients (45.9 %) were informed about the test result via phone call by their doctor. 68.8 % of the patients felt anxious and 26.3 % even felt panic. After having talked to their physician, 51.4 % of our cohort still felt worried and only 24.4 % felt reassured. Concerning disease management, 48.4 % underwent a control Pap smear in 6 months. The preferred information source was the physician (63.9 %). Compared to the results in other European countries, our study cohort showed differences concerning age distribution, patients living in a partnership, number of children and especially disease management. CONCLUSION: Cancer screening itself and abnormal test results have an impact on patient's feelings. To reduce the psychological impact, patients need to be better informed about the risks and benefits of cancer screening programs and in case of cervical cancer screening about the meaning of an abnormal test result. Our results underline the importance of a trustful physician-patient relationship in that matter.

Clinical Impact of Pelvic Sentinel Lymph Node Biopsy for Vulvar Squamous Cell Carcinoma.

BACKGROUND/AIM: This study investigated the clinical impact of resection of pelvic sentinel lymph nodes (PSLNs) in squamous cell vulvar cancer (SCVC). PATIENTS AND METHODS: Sixty-two groins of 33 patients with SCVC who underwent sentinel lymph node (SLN) resection between 2010 and 2021 at the University Hospital of Cologne, Germany, were analyzed in this retrospective cohort study. The frequency of additionally resectable PSLNs, histological findings, and count rates were analyzed and compared to the findings for inguinal sentinel lymph nodes (ISLNs). RESULTS: In all patients and in 61 (98%) of the 62 radiolabeled groins, at least one SLN could be resected. Five (8%) of the 62 groins had histologically confirmed lymph node metastases (4/33 patients, 12%). Twenty (33%) of the 62 groins underwent additional PSLN resection. Resection of these PSLNs was feasible without causing an additional burden for the patients. None of the PSLNs showed signs of tumor infiltration. Information on the extent of radioactivity for ISLNs and simultaneously for PSLNs, expressed as count rate of intraoperative measurement with the gamma probe, was available for 20 (32%) groins. In three (15%) of these cases, the highest count rate in a SLN was found in a PSLN and not in an ISLN. CONCLUSION: Resection of PSLNs is feasible and can be performed without short-term complications. In patients with early SCVC, resection of PSLNs is not necessary, even in those with early infiltration of inguinal lymph nodes. The intraoperative count rate of SLN is not relevant for the decision to perform resection.

Sonographic Assessment of Breast Implants Using Strain Elastography and Shear Wave Elastography in an Animal Model.

BACKGROUND/AIM: To date, magnetic resonance imaging (MRI) remains the gold standard for diagnosing breast implant rupture. As MRI is an expensive procedure with limited availability, the improvement of sonographic assessment is desirable. A potentially useful tool in this regard is elastography. To evaluate the diagnostic benefits of strain elastography and shear wave elastography under standardized conditions we developed an animal model. MATERIALS AND METHODS: An animal model was created by preparing an implant site in a chicken breast, imitating tissue layers covering a breast implant after mastectomy. Different broken and intact implants were inserted. Thereby, measurements were performed using strain elastography and shear wave elastography. For strain elastography, the resulting images were investigated on repeated patterns. The data generated by shear wave elastography were analyzed for significant differences between the ruptured and intact implants. RESULTS: The animal model using chicken breast generated realistic images and measurements comparable to those of a human breast. Hence, ruptured and intact implants could be compared under standardized conditions. Statistical analysis showed no significant difference between intact and ruptured implants with respect to the data generated by shear wave elastography. Qualitative analysis using strain wave elastography showed different patterns between intact and ruptured implants in the animal model. Intact implants showed a characteristic sonographic image of three layers in certain levels. CONCLUSION: Shear wave elastography does not seem to produce reliable data for the evaluation of breast implants, whereas qualitative analysis using strain elastography might be a useful tool to improve diagnostic accuracy.

Staging for Breast Cancer: A Comparison Between Old and New Approaches.

Background/Aim: Staging for breast cancer in advanced stages or prior to neoadjuvant chemotherapy is recommended to be performed with CT scan of the chest and abdomen and a bone scan. This recommendation is valid since 2012, when conventional staging with chest x-ray and ultrasound of the abdomen was replaced by the more sensitive CT scan. However, it remains unclear if this approach improves patient outcome and prognosis. Patients and Methods: We identified patients who were treated for breast cancer at the breast center of the St. Elisabeth Hospital, Cologne, in 2012 and 2014. Clinical information such as age at diagnosis, stage, tumor biology, grading, and the applied method for staging was abstracted from the patient chart. We also looked for local or distant recurrence and data of survival. Results: A total of 1,122 patients were identified. Of those, 104 patients developed local or distant recurrence and 54 died. Conventional staging with chest x-ray, abdominal ultrasound and a bone scan was more often in 2012 (482 cases) than in 2014 (135), but CT-staging was more often in 2014 (180 vs. 29 cases). In general, less patients were staged in 2014 than in 2012. There were no significant survival differences between the two groups. Conclusion: Staging habits changed in 2012 compared to 2014 according to the changes in guidelines. This change did not affect disease-free survival.

Digital droplet PCR-based quantification of ccfHPV-DNA as liquid biopsy in HPV-driven cervical and vulvar cancer.

PURPOSE: More than 99% of cervical cancers and up to 40% of vulvar cancers are human papillomavirus (HPV) related. HPV 16 and 18 are the most relevant subtypes. Novel technologies allow the detection of minimal amounts of circulating cell-free HPV DNA (ccfHPV-DNA). The aim of this study was to evaluate ccfHPV-DNA assessed by droplet digital PCR (ddPCR) as a biomarker for molecular therapy monitoring in early, advanced, relapsed and metastatic HPV-driven cervical and vulvar cancer. METHODS: Inclusion criteria of the study were histologically proven HPV 16/18-driven cervical and vulvar cancer with first diagnosed disease, newly diagnosed recurrence, or progression of disease. Blood samples were taken pre- and post-therapeutically. Circulating cell-free HPV DNA was quantified using ddPCR and the results were correlated with clinical data. RESULTS: The mean copy number of ccfHPV-DNA was 838.6 (± 3089.1) in pretreatment and 2.3 (± 6.4) in post-treatment samples (p < 0.05). The copy number of ccfHPV-DNA increased with higher FIGO stages (p < 0.05), which are commonly used for clinical staging/assessment. Furthermore, we compared the distribution of copy numbers between T-stage 1 versus T-stage 2/3. We could show higher copy number level of ccfHPV-DNA in T-stage 2/3 (p < 0.05). CONCLUSIONS: Therapy monitoring with determination of ccfHPV-DNA by ddPCR with a small amount of plasma reflects response to therapy and appears feasible for patients in advanced cancer stages of cervical and vulvar cancer. This promising tool should be examined as marker of therapy monitoring in particular in novel HPV-directed therapies.

Uterus-preserving management of pyomyoma: Case report of a rare complication after uterine artery embolization.

Background: Pyomyoma of the uterus is a rare but severe complication of uterine artery embolization (UAE). This report describes the uterus-preserving management of a case of fast-developing pyomyoma. Screening methods to minimize the risk of this condition are discussed. Case: A 46-year-old woman presented with fever, abdominal pain and blood stream infection on the third day after UAE, which had been performed to treat symptomatic uterine myomatosus. Broad-spectrum antibiotics proved inadequate. Magnetic resonance imaging (MRI) showed a possible superinfection of the necrotic myoma. Vaginal smear showed the same organism, a resistant Escherichia coli, as in the blood culture. Because the patient declined hysterectomy, multiple hysteroscopies with removal of necrotic pyomyoma were performed. In addition, an intrauterine gentamicin chain was placed. To our knowledge, this is the first case of pyomyoma immediately after UAE and the first report of successful hysteroscopic treatment in a septic patient. Conclusion: In order to reduce the risk of pyomyoma, pre- and postinterventional algorithms should be used.

Evaluation of Real-world Data for Breast-MRI BI-RADS IV Lesions.

BACKGROUND/AIM: Magnetic resonance imaging (MRI) is an important diagnostic tool in the detection of breast cancer. The Breast Center of the municipal Hospital Holweide, Cologne, annually cares for and treats patients with changes in the breast. A special problem is posed by Breast Imaging-Reporting and Data System (BI-RADS) 4 lesions. If a BI-RADS 4 finding is present, is a vacuum biopsy indicated in every case or, if there is already an indication for surgery due to other findings, can the corresponding finding be removed openly without histological clarification? We require real world data regarding the actual in-center likelihood of a BIRADS 4 lesion to be DCIS (Ductal carcinoma in situ) or invasive disease. PATIENTS AND METHODS: This is a retrospective study of 1,641 patients who received MRI examination in the radiological department of the municipal hospital Holweide in 2012 and 2013. Each BI-RADS 4 finding (or higher) classified by MRI was compared with the final histological result. RESULTS: 347 MRIs showed BI-RADS 4 findings or higher and 280 (80.7%) cases showed benign histology. In 67 (19.3%) cases, histology showed DCIS or invasive carcinoma. CONCLUSION: BI-RADS 4 lesions have a low probability of malignancy based on real-world data from this center. If there is already an indication for surgery due to other lesions, the patient can also be offered a simultaneous open biopsy in the context of the already initiated surgical treatment. Each center should know the sensitivity and specificity of the MRI imaging performed and counsel patients based on that.

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 µg misoprostol escalated to 100 and, subsequently, to 200 µg every 4 h with a daily maximum of 600µg, between 11/2007 and 01/2008; and Group B (n=61), which initially received 25 µg misoprostol followed by 100 µg every 4 h with a daily maximum of 300 µg, 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 meconium-stained 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.

Morbidity and quality of life in patients with vulvar cancer after inguinal sentinel lymphadenectomy compared to radical inguinofemoral lymphadenectomy.

AIM: Probability of survival of patients with vulvar cancer directly depends on the lymph node status. Surgery of lymph nodes can be performed as radical inguinofemoral lymphadenectomy or in cases with certain conditions as sentinel lymph node surgery. The aim of this study is to obtain an overview of the intervention-related morbidity and quality of life in patients with vulvar carcinoma after lymphadenectomy. METHODS: Quality of life and morbidity was compared between patients who underwent radical inguinofemoral lymphadenectomy with those who underwent sentinel lymph node surgery. RESULTS: All recorded postoperative complications occur more frequently in the non-sentinel group, Significant difference was shown for the occurrence of lymphedema (p-value = 0.024) and sensitivity loss (p-value = 0.024). Recurrence of disease was more frequent in the non-sentinel group (38 % vs. 20 %, p = 0.621, n.s.) and satisfaction with groin surgery is slightly higher in the sentinel group (94 % vs. 89 %, p = 1.000, n.s.). CONCLUSION: We could demonstrate a significantly lower morbidity of sentinel lymphadenectomy compared to conventional inguinofemoral lymphadenectomy while maintaining the same oncological safety. The low morbidity of sentinel- lymphadenectomy does not seem to influence the postoperative quality of life significantly. However, recording of the individual burden of lymphadenectomy by questionnaires should be optimized.

Preoperative Octenidine Application in Breast Reconstruction Surgery.

BACKGROUND/AIM: Postoperative infection in implant-based reconstructive breast surgery is a common problem. The preoperative application of a disinfecting washing agent may reduce postoperative infection rates. This retrospective analysis aimed to evaluate whether preoperative Octenisan® application yields a reduction in postoperative complications or infection rates in breast reconstructive surgery. PATIENTS AND METHODS: Between 2016 and 2019, 127 women received implant-based breast reconstruction at the municipal hospital of Cologne, Holweide, Germany. A total of 197 treatments were performed. After giving consent, patients were asked to use Octenisan® wash lotion for five days before breast reconstructive surgery. All patients were asked by a simple questionnaire whether they performed showering and washing according to the proposed protocol. In 96 cases patients did adhere to the protocol. In 101 cases they did not. Patient cohorts were then divided into patients who had applied Octenisan® wash lotion and patients who had not. Endpoints were defined as minor complications with no implant loss and major complications with consecutive implant loss. RESULTS: Patient adherence to the application regimen was 48.7%. Overall minor complications occurred in 34.4% with preoperative Octenidine usage and 36.6% without preoperative Octenidine usage. Major complications happened in 7% with preoperative Octenidine and 5% without Octenidine. Overall, there was no significant difference concerning minor or major complication rates. CONCLUSION: Preoperative washing protocols involving the Octenisan® wash lotion is relatively cheap and easy to follow. There is evidence that washing protocols result in a reduction of S. aureus infections leading to a better perioperative outcome. Octenisan® is safe to use in implant-based breast reconstructive surgery and is not associated with higher risks for patients. Our study did not yield any significant reduction in perioperative and postoperative complication and infection rates. This is attributed to a relatively low study population. Wash lotion compliance was only 48.7%. Proper patient education is crucial. With those preliminary data, it is now possible to design a larger analysis since patient adherence to washing protocol with Octenisan® wash lotion has been established.

CD86+ Antigen-Presenting B Cells Are Increased in Cancer, Localize in Tertiary Lymphoid Structures, and Induce Specific T-cell Responses.

The role of B cells in antitumor immunity and their impact on emerging immunotherapies is increasingly gaining attention. B-cell effector functions include not only secretion of antibodies, but also presentation of antigens to T cells. A physiologic B-cell subset with immunostimulatory properties was described in humans, defined by a high expression of CD86 and downregulation of CD21. We used multicolor flow cytometry and IHC to elucidate abundance and spatial distribution of these antigen-presenting B cells (BAPC) in blood (peripheral blood mononuclear cells, PBMC) and tumor samples of 237 patients with cancer. Antigen-specific T-cell responses to cancer testis antigens were determined using tetramer staining and sorted BAPCs in FluoroSpot assays for selected patients. We found that BAPCs were increased in the tumor microenvironment of 9 of 10 analyzed cancer types with site-specific variation. BAPCs were not increased in renal cell carcinoma, whereas we found a systemic increase with elevated fractions in tumor-infiltrating lymphocytes (TIL) and PBMCs of patients with colorectal cancer and gastroesophageal adenocarcinoma. BAPCs were localized in lymphoid follicles of tertiary lymphoid structures (TLS) and were enriched in tumors with increased numbers of TLSs. BAPCs isolated from tumor-draining lymph nodes of patients with cancer showed increased percentages of tumor antigen-specific B cells and induced responses of autologous T cells in vitro. Our results highlight the relevance of BAPCs as professional antigen-presenting cells in tumor immunity and provide a mechanistic rationale for the observed correlation of B-cell abundance and response to immune checkpoint inhibition.
