Primary results of the AGO-Zervix-1 Study: A prospective, randomized phase III study to compare the effects of paclitaxel and topotecan with those of cisplatin and topotecan in the treatment of patients with recurrent and persistent cervical cancer.

BACKGROUND: Before the era of immunotherapies and antibody-drug conjugates, there were limited chemotherapeutic options for patients with recurrent and metastatic cervical cancer. Combination therapies with cisplatin have shown some superiority over monotherapy. This study examined platinum-free treatment regimens, comparing a combination of topotecan and paclitaxel (TP) with topotecan and cisplatin (TC) in patients with recurrent or metastatic cervical cancer, with or without prior platinum-based treatment. METHODS: The AGO-Zervix-1 Study (NCT01405235) is a prospective, randomized phase III study in which patients were randomly assigned at a 1:1 ratio to treatment within the control arm with topotecan (0.75 mg/m2) on days 1-3 and cisplatin (50 mg/m2) on day 1 every 3 weeks and in the study arm topotecan (1.75 mg/m2) and paclitaxel (70 mg/m2) on days 1, 8, and 15 every 4 weeks or treatment. The primary study aim was overall survival; progression-free survival, toxicity, and quality of life were secondary aims. The interim and final analysis is here reported after recruitment of 173 of 312 planned patients. RESULTS: Median overall survival in the TP arm was 9.6 months, compared with 12.0 months in the TC arm (log-rank test, P = 0.33). Median progression-free survival rates were 4.4 months with TP and 4.2 months with TC (log-rank test, P = 0.47). Leukopenia and nausea/vomiting were more frequent in the cisplatin-containing arm. Otherwise, toxicity profiles were comparable. There were no differences in FACT-G-assessed quality of life. CONCLUSION: Platinum-based combination chemotherapy remains the standard of care chemotherapy regimen for patients with recurrent or metastatic cervical cancer.

Gestational and Non-gestational Trophoblastic Neoplasia. Guideline of the DGGG, OEGGG and SGGG (S2k-Level, AWMF Registry No. 032/049, April 2022).

Purpose The aim was to develop and update a guideline which would improve the quality of care offered to women with gestational and non-gestational trophoblastic disease, a group of diseases characterized by their rarity and biological heterogeneity. Methods In accordance with the method used to compile S2k-guidelines, the guideline authors carried out a search of the literature (MEDLINE) for the period 1/2020 to 12/2021 and evaluated the recent literature. No key questions were formulated. No structured literature search with methodical evaluation and assessment of the level of evidence was carried out. The text of the precursor version of the guideline from 2019 was updated based on the most recent literature, and new statements and recommendations were drafted. Recommendations The updated guideline contains recommendations for the diagnosis and therapy of women with hydatidiform mole (partial and complete moles), gestational trophoblastic neoplasia after pregnancy or without prior pregnancy, persistent trophoblastic disease after molar pregnancy, invasive moles, choriocarcinoma, placental site nodules, placental site trophoblastic tumor, hyperplasia at the implantation site und epithelioid trophoblastic tumor. Separate chapters cover the determination and assessment of human chorionic gonadotropin (hCG), histopathological evaluation of specimens, and the appropriate molecular pathological and immunohistochemical diagnostic procedures. Separate chapters on immunotherapy, surgical therapy, multiple pregnancies with simultaneous trophoblastic disease, and pregnancy after trophoblastic disease were formulated, and the corresponding recommendations agreed upon.

Sarcoma of the Uterus. Guideline of the DGGG, OEGGG and SGGG (S2k-Level, AWMF Registry No. 015/074, April 2021).

Purpose This is an official guideline, published and coordinated by the Germany Society for Gynecology and Obstetrics (Deutsche Gesellschaft für Gynäkologie und Geburtshilfe, DGGG). Because of their rarity and heterogeneous histopathology, uterine sarcomas are challenging in terms of their clinical management and therefore require a multidisciplinary approach. To our knowledge, there are currently no binding evidence-based recommendations for the appropriate management of this heterogeneous group of tumors. Methods This S2k guideline was first published in 2015. The update published here is once again the result of the consensus of a representative interdisciplinary committee of experts who were commissioned by the Guidelines Committee of the DGGG to carry out a systematic search of the literature on uterine sarcomas. Members of the participating professional societies achieved a formal consensus after a structured consensus process. Recommendations 1.1 Epidemiology, classification, staging of uterine sarcomas. 1.2 Symptoms, general diagnostic workup, general pathology or genetic predisposition to uterine sarcomas. 2. Management of leiomyosarcomas. 3. Management of low-grade endometrial stromal sarcomas. 4. Management of high-grade endometrial stromal sarcoma and undifferentiated uterine sarcomas. 5. Management of adenosarcomas. 6. Rhabdomyosarcomas of the uterus in children and adolescents. 7. Follow-up of uterine sarcomas. 8. Management of morcellated uterine sarcomas. 9. Information provided to patients.

Diagnosis, Therapy and Follow-up of Vaginal Cancer and Its Precursors. Guideline of the DGGG and the DKG (S2k-Level, AWMF Registry No. 032/042, October 2018).

Purpose This is an official guideline, published and coordinated by the Gynecological Oncology Working Group (AGO) of the German Cancer Society (DKG) and the German Society for Gynecology and Obstetrics (DGGG). Vaginal cancers are rare tumors, which is why there is very little evidence on these tumors. Knowledge about the optimal clinical management is limited. This first German S2k guideline on vaginal cancer has aimed to compile the most current expert knowledge and offer new recommendations on the appropriate treatment as well as providing pointers about individually adapted therapies with lower morbidity rates than were previously generally available. The purpose of this guideline is also to set up a register to record data on treatment data and the course of disease as a means of obtaining evidence in future. Methods The present S2k guideline was developed by members of the Vulvar und Vaginal Tumors Commission of the AGO in an independently moderated, structured, formal consensus process and the contents were agreed with the mandate holders of the participating scientific societies and organizations. Recommendations To optimize the daily care of patients with vaginal cancer: 1. Monitor the spread pattern; 2. Follow the step-by-step diagnostic workup based on initial stage at detection; 3. As part of individualized clinical therapeutic management of vaginal cancer, follow the sentinel lymph node protocol described here, where possible; 4. Participate in the register study on vaginal cancer.

Sarcoma of the Uterus. Guideline of the DGGG and OEGGG (S2k Level, AWMF Register Number 015/074, February 2019).

Aims This is an official guideline published and coordinated by the German Society of Gynecology and Obstetrics (DGGG) and the Austrian Society of Gynecology and Obstetrics (OEGGG). Because of their rarity and heterogeneous histopathology, uterine sarcomas are challenging in terms of how they should be managed clinically, and treatment requires a multidisciplinary approach. To our knowledge, there are currently no binding evidence-based recommendations for the appropriate management of this heterogeneous group of tumors. Methods This S2k guideline was first published in 2015. The update published here is the result of the consensus of a representative interdisciplinary group of experts who carried out a systematic search of the literature on uterine sarcomas in the context of the guidelines program of the DGGG, OEGGG and SGGG. Members of the participating professional societies achieved a formal consensus after a moderated structured consensus process. Recommendations The consensus-based recommendations and statements include the epidemiology, classification, staging, symptoms, general diagnostic work-up and general pathology of uterine sarcomas as well as the genetic predisposition to develop uterine sarcomas. Also included are statements on the management of leiomyosarcomas, (low and high-grade) endometrial stromal sarcomas and undifferentiated uterine sarcomas and adenosarcomas. Finally, the guideline considers the follow-up and morcellation of uterine sarcomas and the information provided to patients.

Proliferation and cell-cell fusion of endometrial carcinoma are induced by the human endogenous retroviral Syncytin-1 and regulated by TGF-beta.

Endometrial carcinomas (EnCa) predominantly represent a steroid hormone-driven tumor initiated from prestages. The human endogenous retrovirus HERV-W envelope gene Syncytin-1 was significantly increased at the mRNA and protein levels in EnCa and prestages compared to controls. Steroid hormone treatment of primary EnCa cells and cell lines induced Syncytin-1 due to a new HERV-W estrogen response element and resulted in increased proliferation. Activation of the cAMP-pathway also resulted in Syncytin-1 upregulation, but in contrast to proliferation, classic cell-cell fusions similar to placental syncytiotrophoblasts occurred. Cell-cell fusions were also histologically identified in endometrioid EnCa tumors in vivo. Clonogenic soft agar experiments showed that Syncytin-1 is also involved in anchorage-independent colony growth as well as in colony fusions depending on steroid hormones or cAMP-activation. The posttranscriptional silencing of Syncytin-1 gene expression and a concomitant functional block of induced cell proliferation and cell-cell fusion with siRNAs proved the essential role of Syncytin-1 in these cellular processes. TGF-beta1 and TGF-beta3 were identified as main regulative factors, due to the finding that steroid hormone inducible TGF-beta1 and TGF-beta3 inhibited cell-cell fusion, whereas antibody-mediated TGF-beta neutralization induced cell-cell fusions. These results showed that induced TGF-beta could override Syncytin-1-mediated cell-cell fusions. Interactions between Syncytin-1 and TGF-beta may contribute to the etiology of EnCa progression and also help to clarify the regulation of cell-cell fusions occurring in development and in other syncytial cell tumors.

Acceptance for preventive genetic testing and prophylactic surgery in women with a family history of breast and gynaecological cancers.

The fear of family members of patients with breast or gynaecologic cancer of developing a similar disease is often high. We investigated the acceptance for genetic testing of untested women with a positive family history and their attitude for prophylactic surgery. A total of 659 women with a familial history of breast or gynaecologic cancer were asked to answer a questionnaire regarding their interest in genetic testing for breast cancer as well as for gynaecologic carcinoma and their interest in prophylactic surgery. Genetic testing is seen to be accepted by the majority of participants: 85.0 and 77.8% chose a genetic test for breast and gynaecologic cancer, respectively. Prophylactic surgery was much less chosen; prophylactic mastectomy as well as prophylactic hysterectomy or bilateral prophylactic oophorectomy was an option only for a minority of women. Genetic testing for risk assessment of healthy women with a positive family history was observed to be accepted by a majority of participants. Prophylactic surgery was an option only for a minority and was not acceptable for most of the women.

Effects of the antiestrogens tamoxifen and raloxifene on the estrogen receptor transactivation machinery.

The influence of 17beta-estradiol (E2), tamoxifen (TAM) and raloxifen (RLX) on the proliferation of breast (BC) and endometrial carcinoma cell lines (EC) and the expression of different compounds of the estrogen receptor (ER)-transactivation machinery were studied. E2 stimulated the proliferation of BC, but had no effect on the EC. TAM showed a biphasic effect on ER-positive cell lines. RLX showed an antagonistic suppression or no effect. The expression of ERalpha was down-regulated by E2, but not affected by selective estrogen receptor modulators. ERbeta and progesterone receptor expressions were up-regulated by E2, TAM and OHT. This supports the hypothesis that ERbeta expression is also regulated via the ERalpha-pathway. The steroid receptor coactivator (SRC) AIB1 expression was slightly decreased by E2 but not by antiestrogens (antiE). TIF2 expression was increased by E2, TAM and RLX, but SRC-1 expression was not. In comparison, the expressions of ERbeta and progesterone receptor were strongly influenced by antiE, while the expression of SRCs was only slightly affected.

Age of uptake of early cancer detection facilities by low-risk and high-risk patients with familial breast and ovarian cancer.

INTRODUCTION: Some 5-10% of all cases of breast cancer and ovarian cancer have a hereditary genesis. In the setting of an interdisciplinary cancer genetics clinic, a study of the age at which patients first take advantage of early cancer detection (ECD) facilities was conducted in order to assess the influence of familial risk on health issues. METHODS: The study included 556 women who fulfilled the inclusion criteria (IC) for genetic analysis of the BRCA1 and BRCA2 genes, as well as 205 who did not meet these criteria but attended the primary consultation. RESULTS: Consulters who met the inclusion criteria took advantage of nearly all methods of ECD at an earlier time than women who did not. A comparison of consulters with or without breast cancer showed that those without breast cancer participated in all methods of ECD at an earlier time. CONCLUSION: Methods of improving and increasing participation in ECD facilities, and of encouraging women who are at risk to start on such programs at a younger age, need to be discussed. In this study, familial risk already resulted in a younger age of uptake of ECD facilities.

Awareness of general and personal risk factors for uterine cancer among healthy women.

Participation rates in gynaecological cancer screening are influenced by different factors. The knowledge of general and personal risk factors for uterine cancer among women might influence their interest in gynaecological cancer screening. Two thousand nine hundred women in 23 gynaecological outpatient services were invited to answer a structured questionnaire regarding general and personal risk factors for cervical and endometrial carcinoma; 2108 women participated. Women with a history of cancer were excluded from the study. It was found that levels of knowledge about uterine carcinoma were low. Only 47.4% of women knew the difference between the sites of origin of cervical and endometrial cancer. Seventy-seven per cent of participants assessed their knowledge about uterine malignancies as insufficient; 96.3% would appreciate more information about uterine cancer. Younger women were significantly less well informed than postmenopausal women. Known risk factors such as smoking or human papillomavirus (HPV) infection as factors for cervical cancer were underestimated; most women assessed genetic factors as most important for the development of uterine cancer. The level of information about risk factors as well as general facts about gynaecological cancer in women is low. Ameliorating this lack of information might influence the perception of uterine cancer and result in higher participation rates in gynaecological cancer screening.

The Hohl instrument for optimizing total laparoscopic hysterectomy procedures.

STUDY OBJECTIVE: To evaluate the feasibility of total laparoscopic hysterectomy (TLH) using the Hohl instrument in an initial cohort of patients. DESIGN: Retrospective cohort analysis (Canadian Task Force classification II-3). SETTING: Department of Obstetrics and Gynecology, Erlangen University Hospital, Erlangen, Germany. PATIENTS: Forty-four women underwent the new TLH procedure using the Hohl instrument from May 2004 through January 2005. The laparoscopic approach was used when the patient had undergone more than one previous pelvic abdominal operation and/or had a reduced vaginal capacity. The indications for hysterectomy were symptomatic leiomyoma in 25 patients and hypermenorrhea in 19 patients. INTERVENTION: Total laparoscopic hysterectomy using the Hohl instrument. MEASUREMENTS AND MAIN RESULTS: No ureteral or bladder injury occurred in any of the patients. The complication rate during surgery and in the postoperative period was zero. The mean loss of hemoglobin was 1.68+/-0.96 g/dL, the mean operating time was 108+/-21 minutes, and the mean uterine weight was 302+/-121 g. CONCLUSION: Total laparoscopic hysterectomy using the Hohl instrument simplifies the surgical procedure. The reported technique is an option comparable with laparoscopic-assisted vaginal hysterectomy and may be effective in preventing minor and major complications during TLH.

Systematic aortic and pelvic lymphadenectomy versus resection of bulky nodes only in optimally debulked advanced ovarian cancer: a randomized clinical trial.

BACKGROUND: The role of systematic aortic and pelvic lymphadenectomy in patients with optimally debulked advanced ovarian cancer is unclear and has not been addressed by randomized studies. We conducted a randomized clinical trial to determine whether systematic aortic and pelvic lymphadenectomy improves progression-free and overall survival compared with resection of bulky nodes only. METHODS: From January 1991 through May 2003, 427 eligible patients with International Federation of Gynecology and Obstetrics (FIGO) stage IIIB-C and IV epithelial ovarian carcinoma were randomly assigned to undergo systematic pelvic and para-aortic lymphadenectomy (n = 216) or resection of bulky nodes only (n = 211). Progression-free survival and overall survival were analyzed using a log-rank statistic and a Cox multivariable regression analysis. All statistical tests were two-sided. RESULTS: After a median follow-up of 68.4 months, 292 events (i.e., recurrences or deaths) were observed, and 202 patients had died. Sites of first recurrences were similar in both arms. The adjusted risk for first event was statistically significantly lower in the systematic lymphadenectomy arm (hazard ratio [HR] = .75, 95% confidence interval [CI] = 0.59 to 0.94; P = .01) than in the no-lymphadenectomy arm, corresponding to 5-year progression-free survival rates of 31.2 and 21.6% in the systematic lymphadenectomy and control arms, respectively (difference = 9.6%, 95% CI = 1.5% to 21.6%), and to median progression-free survival of 29.4 and 22.4 months, respectively (difference = 7 months, 95% CI = 1.0 to 14.4 months). The risk of death was similar in both arms (HR = 0.97, 95% CI = 0.74 to 1.29; P = .85), corresponding to 5-year overall survival rates of 48.5 and 47%, respectively (difference = 1.5%, 95% CI = -8.4% to 10.6%), and to median overall survival of 58.7 and 56.3 months, respectively (difference = 2.4 months, 95% CI = -11.8 to 21.0 months). Median operating time was longer, and the percentage of patients requiring blood transfusions was higher in the systematic lymphadenectomy arm than in the no-lymphadenectomy arm (300 versus 210 minutes, P<.001, and 72% versus 59%; P = .006, respectively). CONCLUSION: Systematic lymphadenectomy improves progression-free but not overall survival in women with optimally debulked advanced ovarian carcinoma.

Interstitial brachytherapy alone after breast conserving surgery: interim results of a German-Austrian multicenter phase II trial.

PURPOSE: To evaluate the value of interstitial brachytherapy (iBT) alone in the treatment of low-risk breast cancer patients with regard to local control, side effects, and cosmesis. METHODS AND MATERIALS: From November 2000 to January 2004, 176 patients with low-risk breast cancer were treated with iBT only. Patients were eligible for entering the study if: the tumor size was <3 cm; resection margins were clear by at least 2 mm; there were no lymph node metastases or only one micrometastasis (pNo, pNmi); age was >35 years; steroid hormone receptor was positive; and histologic grade was 1 or 2. Seventy-five percent of patients received pulsed-dose-rate brachytherapy (D(ref) = 50 Gy); 25% of patients received high-dose-rate brachytherapy (D(ref) = 32.0 Gy). An interim analysis is presented for all patients after an interim follow-up of 12 months, and for half the patient population with an interim follow-up of 21 months. RESULTS: All patients remained disease-free on the date of analysis. A perioperative complication breast infection was recorded for 1/176 (0.6%) patients. Late toxicity i.e., hypersensation, hyperpigmentation, fibrosis, or teleangiectasia was observed in 1-12% of all patients. Grade I Fibrosis was registered in 7.6% (13/172) and grade II in 7.0% (12/172) of evaluable patients. Similarly, grade I teleangiectasia was observed in 4.7% (8/172), grade II in 0.6% (1/172), and grade III also in 0.6% (1/172) of evaluable patients. Excellent or good cosmetic results have been observed in 92-95% of patients. CONCLUSIONS: Brachytherapy as monotherapy in low-risk breast cancer patients after breast-conserving surgery is an effective, precise treatment modality without perioperative morbidity, low acute, mild late toxicity, and yields good to excellent cosmetic results.

An interleukin-6 gene promoter polymorphism influences the biological phenotype of ovarian cancer.

Interleukin (IL)-6 is known to be involved in the pathogenesis of ovarian cancer. We investigated a common G/C polymorphism at position -174 of the IL-6 gene (IL6) promoter in 121 patients with ovarian cancer using pyrosequencing. Presence of at least one mutant allele was associated with early tumor stage as well as an expanded length of disease-free (DFS) and overall survival with a dose-dependent effect regarding the carriage of 0, 1, and 2 alleles. In a multivariate Cox regression model incorporating tumor stage and residual tumor mass, presence of the -174 C allele of IL6 was the best predictor of DFS. We conclude that the mutant -174 C allele of IL6 influences the biological phenotype of ovarian cancer because it is associated with early stage and improved DFS and overall survival.
