IL-23, IFN-α, and IFN-ß in the vaginal fluid of patients suffering from vulvovaginal candidosis.

Purpose of the investigation: Vulvovaginal candidosis (VVC) is a common vaginal infection affecting almost 75% of all women once per lifetime. Vaginal associated immunity is important in the protection against VVC. The purpose of this study was to evaluate a potential role of IL-23, IFN-α, and IFN-ß in the local immune response against VVC. MATERIALS AND METHODS: The study included 202 non-pregnant women; 71 patients with clinical symptoms of VVC and 131 asymptomatic patients served as control. IL-23, IFN-α, and IFN-ß were measured in the vaginal fluid by ELISA. Microbiological cultures were used for Candida detection. RESULTS: C. albicans was detected in 67.6% of patients, C. glabrata in 2 1.1% of patients, and 5.6% were infected with C. krusei or coinfected with C. albicans and C. krusei. Levels of IL-23 (p < 0.001) and IFN-ß (p < 0.017) were significantly lower in the VVC group. IFN-α was elevated in the VVC group compared to the asymptomatic patients (p < 0.001). CONCLUSION: IL-23 and IEFN-ß seem to play a protective role against VVC. Decreased levels in VVC patients suggest a compromised local immune response at the time of occurrence of symptoms. In contrast, IFN-α seems to be released once the infection has occurred. These cytokines may be prospective targets in the treatment and prevention of primary and recurrent vaginal infections with Candida species.

HPV Vaccination: Attitude and Knowledge among German Gynecologists.

Purpose: In order to achieve a higher vaccination rate, education on HPV as well as options for prophylaxis performed by doctors is of great importance. One opportunity to increase the protection against HPV would be vaccinating boys. This study evaluated attitude and knowledge among German gynecologists regarding HPV vaccination, especially in boys. Material and Methods: A questionnaire with 42 questions about demographics, attitude and knowledge about HPV and HPV vaccination was sent to members of the German Society for Gynecology and Obstetrics (DGGG). Results: 998 out of 6567 addressed gynecologists participated. Knowledge about HPV, associated diseases and possible HPV vaccines was high among participants. The attitude towards vaccination in boys as well as girls was positive. Only 8.2 % refused to vaccinate their sons whereas 2.2 % refused to do this for their daughters. However, only few gynecologists vaccinated their daughters and sons against HPV. Main reason for girls was an age outside of vaccination guidelines; for boys it was the lack of cost coverage. Conclusion: The willingness of gynecologists to perform HPV vaccination in boys is as high as for girls. However, sons of gynecologists are only rarely vaccinated against HPV. Main reason is the lack of cost coverage. Vaccinating boys could decrease the disease burden in males, as well as protect women by interrupting ways of transmission. Since the main argument against vaccination of boys is only of financial nature, the necessity of a vaccination recommendation for boys needs to be re-evaluated taking into account the cost-reduced 2-dose vaccination scheme.

Impact of guideline-based use of uPA/PAI-1 on patient outcome in intermediate-risk early breast cancer.

The purpose of this study was to evaluate the influence of guideline-based prospective use of uPA/PAI-1 on clinical outcome in an intermediate-risk cohort of breast cancer patients. We analyzed 381 consecutive primary breast cancer patients (2003-2011) at the breast center Ostbayern meeting the following criteria: M0/N0/estrogen receptor (ER)+/G2. Clinical-pathological data, uPA/PAI-1, and follow-up data were collected. Decisions for adjuvant chemotherapy were made upon consideration of prospectively measured uPA/PAI-1. Observed disease-free survival (DFS) and overall survival (OS) were calculated by Kaplan-Meier estimates. Using guideline-based analysis of uPA/PAI-1, treatment with adjuvant chemotherapy was avoided in 86.5 % of patients with low uPA/PAI-1, i.e., 38.8 % of the total patient collective. Median follow-up was 52.5 months. Five-year relapse-free survival in intermediate-risk patients (N0, G2) without chemotherapy was 99 %. Five-year overall survival including all causes of death was 95 %. By using uPA/PAI-1, adjuvant chemotherapy can be avoided in a major part of patients with intermediate-risk breast cancer. Nevertheless, DFS and OS of these patients at 5 years remain excellent. The potential, but hardly measurable, benefit of adjuvant chemotherapy has to be set in contrast with its associated side effects and increased morbidity. Patients with high uPA/PAI-1 show benefit from chemotherapy. In this subgroup, a very good OS was observed as well. These findings strongly support the use of uPA/PAI-1 together with clinic-pathological parameters as an evidence-based, clinically relevant and inexpensive decision tool in the routine of a breast center.

Surgical management of ipsilateral breast tumor recurrence.

PURPOSE: Approximately 10-15% of breast cancer patients treated by breast conserving surgery (BCS) and adjuvant radiotherapy (RT) will develop ipsilateral breast tumor recurrence (IBTR). International guidelines suggest total mastectomy as treatment of choice for IBTR following lumpectomy and RT. Nevertheless, there is evidence that second BCS might be equally sufficient. PATIENTS AND METHODS: Patients with IBTR diagnosed between 1990 and 2014 after BCS and RT were included (n = 170). 34.1% women underwent secondary BCS, whereas 65.9% were treated by mastectomy. We determined predictive factors for time to local progression (TTP), disease free survival (DFS), and overall survival (OS) comparing these two groups. RESULTS: Median follow-up after primary IBTR was 49 months (59 months for patients still alive at time of analysis). Five-year IBTR-free rate after secondary BCS was 77.6% (SD ± 6.1%) and 75.0% (SD ± 4.5%) for patients after mastectomy. Five-year DFS was 57.3% (SD ± 8.2%), and 61.9% (SD ± 5.5%), five-year OS was 84.7% (SD ± 5.8%), and 72.6% (SD ± 5.1%), respectively. Prior adjuvant systemic therapy, muscular invasion, and skin infiltration were independent significant risk factors for a shorter TTP. Additionally, lymphovascular infiltration (LVI) in the IBTR increased the risk for a shorter DFS. LVI, muscular invasion, and skin infiltration were identified as independent significant risk factors for a shorter OS. CONCLUSION: No significant difference in local control, DFS, and OS was seen between IBTR patients treated either by secondary BCS or mastectomy. Our data suggest that secondary BCS for IBTR patients after initial BCS and RT is feasible in selected patients.

Dose-dense intensified sequential versus conventionally-dosed anthracycline and taxane-containing neoadjuvant therapy in patients with inflammatory breast cancer.

BACKGROUND: This post-hoc analysis aimed to compare an intense dose-dense sequential chemotherapy (DD-CT) and a conventionally-dosed chemotherapy (CD-CT) in the neoadjuvant AGO-1 study, focusing on the subgroup with inflammatory breast cancer (IBC). PATIENTS AND METHODS: Out of 668 randomised patients, 101 patients presented with IBC. Patients received epirubicin followed by paclitaxel every 2 weeks (DD-CT) or simultaneously every 3 weeks (CD-CT). RESULTS: No differences in pathological complete response rates were observed [odds ratio (OR)=1.27, p=0.33]. Most patients were scheduled for mastectomy before starting therapy; however, in 21.7% breast-conserving surgery was performed. Disease-free survival rates [Hazard Ratio (HR)=0.65; p=0.597] and overall survival rates (HR=1.40; p=0.327) were similar for both treatment arms. Patients with breast-conserving surgery had a significantly better outcome than patients treated with mastectomy (disease-free survival: HR=0.41; p=0.034 and overall survival: HR=0.09; p=0.003). CONCLUSION: Patients with IBC benefited not from DD-CT but from breast-conserving surgery after neoadjuvant chemotherapy.

Retinoid X receptor alpha (RXRα) and peroxisome proliferator-activated receptor gamma (PPARγ) expression in breast cancer: an immunohistochemical study.

BACKGROUND/AIM: The role of retinoid X receptor alpha (RXRα) and peroxisome proliferator-activated receptor gamma (PPARγ) in breast cancer has been well studied in vitro. The aim of the study was to assess the presence of these molecules in human breast cancer specimens and correlate them with major clinicopathological features. PATIENTS AND METHODS: Tissue sections from 82 breast cancer cases clustered according to histological grade, lymph node (LN) and hormone receptor (HR) status were assessed by immunohistochemistry for RXRα and PPARγ. RESULTS: RXRα was found to be strongly and moderately expressed in 11 (14.10%) and 33 (42.31%) cases, respectively. PPARγ was found to be strongly and moderately expressed in 33 (41.25%) and 25 (31.25%) cases, respectively. Only RXRα expression was inversely correlated with histological grade. Surprisingly, significantly elevated PPARγ expression was found in cases with positive LN status. Survival analysis did not yield significant results. CONCLUSION: Our data support the current thesis of RXRα being a potential target for feature molecular interventions.

Career and Family - Are They Compatible?: Results of a Survey of Male and Female Gynaecologists in Germany.

Purpose: Nowadays, most gynaecologists are female and the compatibility of job-related career and family life is an upcoming issue. The working group "Gender and Career" of the German Society for Gynaecology and Obstetrics (DGGG) designed a survey to reflect the present situation with a focus on the compatibility of career and family. Material and Methods: A web-based 74-item survey was filled out by members of the DGGG. In total, there were 1037 replies, 75 % female (n = 775) and 25 % male (n = 261) gynaecologists. Results: 62 % of the female and 80 % of the male respondents had already finished their doctoral theses and 2 % female and 13 % male had finished their PhD. Mean number of children was 1.06 (SD 1.08) in female and 1.68 (SD 1.34) in male gynaecologists. The majority of females desired day care for their children, but only 5 to 13 % of employers offer any day care. 88 % of the female and 72 % of the male physicians think that job-related career and family are not compatible. Conclusion: The majority of female gynaecologists wished to have professional child care, but most employers or other institutions do not offer this. This might be one of the reasons why career and family appear incompatible.

The significance of HPV in the follow-up period after treatment for CIN.

PURPOSE OF INVESTIGATION: High-risk anogenital human papillomavirus (HPV) infections are causally related to cervical cancer. Successful treatment of cervical intraepithelial neoplasia (CIN) results in complete eradication of HPV in most cases. There is an increasing interest regarding the role of HPV testing in the follow-up period after treatment for CIN. PATIENTS AND METHODS: This retrospective study includes 107 women who underwent conization for histologically verified CIN. All of them had HPV testing pre- and postoperatively. HPV testing was carried out using a hybrid capture assay (HC2). The mean follow-up period was 21.4 months (range 2-76 months). The data were analyzed with respect to success of conization, HPV persistence/recurrence and CIN recurrence. Sensitivity, specificity and negative predictive value (NPV) of HPV testing were assessed and compared to the cytological results. RESULTS: Preoperatively, 97 of 107 women were HPV positive. Ninety-seven conizations showed negative resection margins with 86 women becoming HPV negative. In the following months, nine of these HPV negative women became HPV positive again. Out of ten conizations with positive resection margins, six women became HPV negative. Recurrent CIN 2/3 lesions were observed in 11 women, nine of whom had persistent positive HPV testing throughout the entire study period. Regarding CIN recurrence HPV testing showed a sensitivity of 93%, a specificity of 85% and a NPV of 99%. CONCLUSIONS: The sensitivity of HPV testing concerning persistent or recurrent CIN as well as the NPV are high. The present data suggest that HPV testing should be integrated in a follow-up algorithm after treatment for CIN by conization.

Supraclavicular lymph node metastases of unknown origin: HPV-typing identifies the primary tumour.

Cancers of unknown primary origin (CUP) account for 0.5-10% of all malignancies. CUP patients with metastases have a median survival of approximately 6 months, despite therapy. Identification of the primary tumour site may offer the opportunity of a specific and more efficient treatment. The case of a 45-year-old woman with supraclavicular lymph node metastases of a squamous cell CUP is reported. A staging laparoscopy with multiple biopsies and a loop diathermy excision of the cervix were performed. Human papillomavirus (HPV)-testing in the tissues revealed the tumour cells as metastases of an occult cervical cancer. Primary platin-based chemotherapy combined with paclitaxel leads to a complete apparative remission. Twelve months later, staging positron emission tomography with 2-[18F]fluoro-2-deoxy-D-glucose in combination with computed tomography identified an isolated left renal lymph node metastasis. The patient received targeted radiation therapy, combined with cisplatin. To date, 19 months after diagnosis, she is doing well without any evidence of disease. The presented case report addresses the difficulties involving the identification of CUP. HPV-DNA is found in over 95% of cervical cancers. As the presented case illustrates, testing for this virus DNA in human tissues can be a useful diagnostic tool in patients with CUP where cervical cancer is the possible primary tumour.

Contextual factors in shared decision making: a randomised controlled trial in women with a strong suspicion of breast cancer.

Decision aids in North American breast cancer outpatients have been shown to assist with treatment decision making and reduce decisional conflict. To date, appropriate delivery formats to effectively increase patient participation in newly diagnosed breast cancer inpatients have not been investigated in the context of German health care provision. The impact of a decision aid intervention was studied in patients (n=111) with a strong suspicion of breast cancer in a randomised controlled trial. The primary outcome variable was decisional conflict. Participants were followed up 1 week post-intervention with a retention rate of 92%. Analyses revealed that the intervention group felt better informed (eta(p)(2)=0.06) but did not experience an overall reduction in decisional conflict as compared with the control group. The intervention had no effect on uptake rates of treatment options, length of consultation with the surgeon, time point of treatment decision making, perceived involvement in decision making, neither decision related nor general patient satisfaction. Patients who received the decision aid intervention experienced a small benefit with regards to how informed they felt about advantages and disadvantages of relevant treatment options. Results are discussed in terms of contextual factors and individual differences as moderators of treatment decision aid effectiveness.

The high-grade endometrial sarcoma: a rare entity.

INTRODUCTION: With an estimated incidence of one to two per one million women, the endometrial stromal sarcoma (ESS) is a rare disease. It is subclassified into a high-grade and a prognostically better low-grade type. Evidence-based data for a standardized therapy is lacking. CASE REPORT: A 32-year-old obese nulligravida presented with persistent vaginal bleeding after the operation of an acute adnextorsion at another hospital. The repeat gynecological ultrasound examination showed a 5.3x5.3x3.6 cm vascularized, partially inhomogeneous mass in the uterus. A fractioned curettage yielded a differential diagnosis of malignant muellerian mixed tumor or a non-differentiated endometrial sarcoma. For completion of the operative treatment, laparotomy with hysterectomy, adnexectomy, and pelvine lymphonodectomy were performed. The final histological report described a 7 cm non-differentiated endometrial sarcoma with infiltration of the left ovary and 25 tumor-free lymph nodes. DISCUSSION: Standard therapy for resectable sarcoma is abdominal hysterectomy and bilateral adnexectomy. So far, there is little data from studies reporting radio- or chemotherapy treatment of small patient numbers in an adjuvant setting. CONCLUSION: The ESS is a very rare disease of the uterus. Due to missing clinical data, it remains a multidisciplinary therapeutic challenge requiring individual decisions. To receive more information on this rare disease, treatment should be performed according to international protocols.

Reduction mammaplasty in granular cell tumour of the breast.

Granular cell tumour of the breast is a rare peripheral nerve tumour. A case in a 34-year-old woman is reported. The clinical and histological differentiation from invasive malignant neoplasm and the surgical management are discussed. Core needle biopsy preoperatively is able to establish the definite diagnosis and help to avoid surgical overtreatment.

[Adjuvant treatment of breast cancer in 2004. A review of the 8th consensus conference of St. Gallen and new study results]. / Adjuvante Therapie des Mammakarzinoms 2004. Eine Bewertung der 8. Konsensuskonferenz von St. Gallen und neuer Studienergebnisse.

The emerging evidence gained from randomized controlled trials accelerated the widespread use of adjuvant endocrine and cytotoxic regimens and their combinations for most breast cancer patients. Even for the earliest cancer stages with low-risk tumour profiles, endocrine treatment can be recommended as adjuvant therapy if the tumour is endocrine responsive. The 8th consensus conference on early breast cancer in St. Gallen in 2003 opened a plethora of treatment options to nearly all breast cancer patients. Key issues were the introduction of adjuvant therapy with anastrozole for those postmenopausal patients with contra-indications or intolerability of tamoxifen and the definition of a group of 'more potent' regimens like the FEC- and the taxane-based regimens for high-risk patients. Unfortunately the expert panel did not clearly define any recommendations either for choosing optimal candidates for purely endocrine treatments (which are a valid option for all patients with optimal endocrine responsive disease or arguments against chemotherapy) or for the proper high-risk patients scheduled for more aggressive regimens. In the meantime, new or updated studies have provided additional information helpful for the shared decision-making with our patients. The Canadian MA.17 study revealed a significant benefit from adding a sequential therapy with letrozole after 5 years of tamoxifen compared to tamoxifen alone. Together with the updated evaluation from the ATAC trial and the Italian ITA study, the role of adjuvant treatment with aromatase inhibitors is steadily strengthened. Several studies comparing taxane-based and taxane-free regimens showed significant survival and/or recurrence benefits for the former. These data should be communicated to the patients. In the complex process of decision-making, a profound knowledge of the study results and the early and complete involvement of the woman and her personal beliefs are mandatory.

Chemosensitivity testing in gynecologic oncology--dream or reality?

Cell culture and animal models have played an essential role in the research of new principles of therapy. Many methods for the individualized testing of therapy sensitivity and resistance have been developed, for example, the clonogenic assay. Presently, the ATP-TCA is commercially available as a testing kit. This review gives an overview of the tumor samples that were tested in the oncologic laboratory in the Department of Obstetrics and Gynecology, Munich Grosshadern between 1993 and 2001. All target parameters show a clear trend in favor of sequential, dose-intensified Epirubicin/Paclitaxel therapy. If this trend remains valid for the total number of patients, a significant impact of this new principle of therapy can be expected. By individualized planning of therapy with ATP-TCA testing, therapy in the individual patient could already be performed by the examination of sensitivity in the preoperative biopsy specimen.

[Detection of disseminated tumor cells in bone marrow--currently of no practical therapeutic value]. / Nachweis disseminierter Krebszellen im Knochenmark, Als Prognosefaktor für die Praxis noch nicht therapierelevant.

Development of metastases in cancer patients is usually due to tumour cells seeding from the primary. These disseminated cells can be detected in blood or bone marrow with the aid of immunocytochemical methods. The clinical significance of this is, however, still controversial. With the aim of determining the prognostic value of disseminated tumour cells, a meta-analysis of 20 publications reporting results based on data collected from a total of 2494 breast cancer patients, was carried out. The outcome of the meta-analysis was that 14 of the 20 studies provided evidence suggesting positive bone marrow findings to be an unfavorable prognostic factor. Five out of twelve studies provided multivariate analytic evidence of an impact of bone marrow status on recurrence-free survival. In five out of twelve studies, a univariate analysis showed a positive bone marrow finding to correlate significantly with overall survival, while a multivariate analysis found such a correlation in only two out of six studies. Owing to a lack of standardization, the results of the individual studies are not directly comparable. Against this background it is too early to say whether the detection of disseminated tumour cells in the bone marrow can be used as a prognostic factor with an impact on therapeutic strategies.
