Statement of the Uterus Commission of the Gynecological Oncology Working Group (AGO) on Surgical Therapy for Patients with Stage IA2-IIB1 Cervical Cancer

The presentation of the results of the prospective randomized international multicenter study AGO-OP.8 - CCTG CX.5 - SHAPE at the annual conference of the American Society of Clinical Oncology (ASCO) in 2023 will affect the surgical treatment of early-stage cervical cancer. In the SHAPE study, simple total hysterectomy (experimental arm) was found to be non-inferior to radical hysterectomy (standard arm) to treat patients with early-stage cervical cancer (FIGO stages [2018] IA2 - IB1 ≤ 2 cm with an infiltration depth of < 1 cm); after 3 years' follow-up the pelvic recurrence rate was 2.52% (experimental arm) compared to 2.17% (standard arm) with no statistically significant difference with regards to recurrence-free survival and overall survival rates. After weighing up the results of the SHAPE study published at the conference, the Uterus Organ Commission of AGO is of the opinion that, in addition to the use of radical hysterectomy to treat patients with invasive cervical cancer which is FIGO stage IA2 - IB1 ≤ 2 cm with an infiltration depth of < 1 cm, simple total hysterectomy may also be considered for primary surgical therapy on a case-by-case basis after suitable explanation of the associated risks. It will be necessary to wait for the data of the full publication before discussing whether this approach should be included in official guidelines and defining it as a new therapy standard.

Statement of the Uterus Commission of the Gynecological Oncology Working Group (AGO) on the Use of Primary Chemoimmunotherapy to Treat Patients with Locally Advanced or Recurrent Endometrial Cancer

The publication of two large randomized studies - the ENGOT-EN-6-NSGO/GOG-3031/RUBY trial and the NRG-GY018 trial - which investigated combining chemotherapy with immunotherapy to treat patients with primary advanced or recurrent endometrial cancer (EC) has transformed the clinical study landscape in terms of first-line therapy for affected patients and has set a new standard of therapy. In the ENGOT-EN-6-NSGO/GOG-3031/RUBY trial, the addition of dostarlimab to standard chemotherapy with carboplatin and paclitaxel resulted in a significant and clinically relevant improvement of progression-free survival and overall survival in the overall population, a significant and clinically relevant improvement of progression-free survival and overall survival in the subgroup with dMMR/MSI-high tumors, and a significant and clinically relevant improvement of progression-free survival in the subgroup with pMMR/MSI-low tumors. In the NRG-GY018 trial, the addition of pembrolizumab to standard chemotherapy with carboplatin and paclitaxel resulted in a significant and clinically relevant improvement of progression-free survival in the group with dMMR tumors, and a significant and clinically relevant improvement of progression-free survival in the group with pMMR tumors. As expected, the effect in both trials was much more pronounced in the group of patients with dMMR/MSI-high tumors. According to the assessment of the Uterus Organ Commission of the AGO, all patients with dMMR/MSI-high tumors should receive chemoimmunotherapy and all patients with pMMR/MSI-low tumors who meet the inclusion criteria of the two trials discussed here may have chemoimmunotherapy. For dostarlimab this means: patients with EC recurrence who will not undergo surgery or radiotherapy, patients with stage IIIA, IIIB or IIIC1 disease and a measurable lesion postoperatively, patients with stage IIIA, IIIB or IIIC1 disease with histological findings of serous EC, clear-cell EC or carcinosarcoma with or without a measurable lesion postoperatively, and patients with stage IIIC2 or IV disease with or without a measurable lesion postoperatively. For pembrolizumab this means: patients with EC recurrence (except carcinosarcoma) who will not undergo surgery or radiotherapy, and patients with stage III or IVA disease (except carcinosarcoma) and a measurable lesion postoperatively or with stage IVB disease with or without a measurable lesion.

Endometrial Cancer. Guideline of the DGGG, DKG and DKH (S3-Level, AWMF Registry Number 032/034-OL, September 2022). Part 1 with Recommendations on the Epidemiology, Screening, Diagnosis and Hereditary Factors of Endometrial Cancer, Geriatric Assessment and Supply Structures

Summary The S3-guideline on endometrial cancer, first published in April 2018, was reviewed in its entirety between April 2020 and January 2022 and updated. The review was carried out at the request of German Cancer Aid as part of the Oncology Guidelines Program and the lead coordinators were the German Society for Gynecology and Obstetrics (DGGG), the Gynecology Oncology Working Group (AGO) of the German Cancer Society (DKG) and the German Cancer Aid (DKH). The guideline update was based on a systematic search and assessment of the literature published between 2016 and 2020. All statements, recommendations and background texts were reviewed and either confirmed or amended. New statements and recommendations were included where necessary. Aim The use of evidence-based risk-adapted therapies to treat women with endometrial cancer of low risk prevents unnecessarily radical surgery and avoids non-beneficial adjuvant radiation therapy and/or chemotherapy. For women with endometrial cancer and a high risk of recurrence, the guideline defines the optimum level of radical surgery and indicates whether chemotherapy and/or adjuvant radiation therapy is necessary. This should improve the survival rates and quality of life of these patients. The S3-guideline on endometrial cancer and the quality indicators based on the guideline aim to provide the basis for the work of certified gynecological cancer centers. Methods The guideline was first compiled in 2018 in accordance with the requirements for S3-level guidelines and was updated in 2022. The update included an adaptation of the source guidelines identified using the German Instrument for Methodological Guideline Appraisal (DELBI). The update also used evidence reviews which were created based on selected literature obtained from systematic searches in selected literature databases using the PICO process. The Clinical Guidelines Service Group was tasked with carrying out a systematic search and assessment of the literature. Their results were used by interdisciplinary working groups as a basis for developing suggestions for recommendations and statements which were then modified during structured online consensus conferences and/or additionally amended online using the DELPHI process to achieve a consensus. Recommendations Part 1 of this short version of the guideline provides recommendations on epidemiology, screening, diagnosis, and hereditary factors. The epidemiology of endometrial cancer and the risk factors for developing endometrial cancer are presented. The options for screening and the methods used to diagnose endometrial cancer are outlined. Recommendations are given for the prevention, diagnosis, and therapy of hereditary forms of endometrial cancer. The use of geriatric assessment is considered and existing structures of care are presented.

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.

Recurrent Miscarriage: Diagnostic and Therapeutic Procedures. Guideline of the DGGG, OEGGG and SGGG (S2k-Level, AWMF Registry No. 015/050, May 2022)

Purpose The aim of this guideline is to standardize the diagnosis and therapy of recurrent miscarriage (RM) using evidence from the recent literature. This is done by using consistent definitions, objective evaluations and standardized treatment protocols.

Methods When this guideline was compiled, special consideration was given to previous recommendations in prior versions of this guideline and the recommendations of the European Society of Human Reproduction and Embryology, the Royal College of Obstetricians and Gynecologists, the American College of Obstetricians and Gynecologists and the American Society for Reproductive Medicine, and a detailed individual search of the literature about the different topics was carried out.

Recommendations Recommendations about the diagnostic and therapeutic procedures offered to couples with RM were developed based on the international literature. Special attention was paid to known risk factors such as chromosomal, anatomical, endocrinological, physiological coagulation, psychological, infectious and immune disorders. Recommendations were also developed for those cases where investigations are unable to find any abnormality (idiopathic RM).

Consensus statement for treatment protocols in pressurized intraperitoneal aerosol chemotherapy (PIPAC)

Objectives

Safe implementation and thorough evaluation of new treatments require prospective data monitoring and standardization of treatments. Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is a promising alternative for the treatment of patients with peritoneal disease with an increasing number of suggested drug regimens. The aim was to reach expert consensus on current PIPAC treatment protocols and to define the most important research topics.

Methods

The expert panel included the most active PIPAC centers, organizers of PIPAC courses and principal investigators of prospective studies on PIPAC. A comprehensive literature review served as base for a two-day hybrid consensus meeting which was accompanied by a modified three-round Delphi process. Consensus bar was set at 70% for combined (strong and weak) positive or negative votes according to GRADE. Research questions were prioritized from 0 to 10 (highest importance).

Results

Twenty-two out of 26 invited experts completed the entire consensus process. Consensus was reached for 10/10 final questions. The combination of doxorubicin (2.1 mg/m²) and cisplatin (10.5 mg/m²) was endorsed by 20/22 experts (90.9%). 16/22 (72.7%) supported oxaliplatin at 120 with potential reduction to 90 mg/m² (frail patients), and 77.2% suggested PIPAC-Ox in combination with 5-FU. Mitomycin-C and Nab-paclitaxel were favoured as alternative regimens. The most important research questions concerned PIPAC conditions (n=3), standard (n=4) and alternative regimens (n=5) and efficacy of PIPAC treatment (n=2); 8/14 were given a priority of ≥8/10.

Conclusions

The current consensus should help to limit heterogeneity of treatment protocols but underlines the utmost importance of further research.

Perimenopause and Postmenopause - Diagnosis and Interventions. Guideline of the DGGG and OEGGG (S3-Level, AWMF Registry Number 015-062, September 2020)

Aim The aim of the interdisciplinary S3-guideline Perimenopause and Postmenopause - Diagnosis and Interventions is to provide help to physicians as they inform women about the physiological changes which occur at this stage of life and the treatment options. The guideline should serve as a basis for decisions taken during routine medical care. This short version lists the statements and recommendations given in the long version of the guideline together with the evidence levels, the level of recommendation, and the strength of consensus. Methods The statements and recommendations are largely based on methodologically high-quality publications. The literature was evaluated by experts and mandate holders using evidence-based medicine (EbM) criteria. The search for evidence was carried out by the Essen Research Institute for Medical Management (EsFoMed). To some extent, this guideline also draws on an evaluation of the evidence used in the NICE guideline on Menopause and the S3-guidelines of the AWMF and has adapted parts of these guidelines. Recommendations Recommendations are given for the following subjects: diagnosis and therapeutic interventions for perimenopausal and postmenopausal women, urogynecology, cardiovascular disease, osteoporosis, dementia, depression, mood swings, hormone therapy and cancer risk, as well as primary ovarian insufficiency.

The Prevention of Positioning Injuries During Gynecologic Surgery. Guideline of the DGGG, OEGGG and SGGG (S2k Level, AWMF Registry Number 015/077, October 2020)

Purpose Positioning injuries are relatively common, forensically highly relevant complications of gynecologic surgery. The aim of this official AWMF S2k-guideline is to provide statements and recommendations on how to prevent positioning injuries using the currently available literature. The literature was evaluated by an interdisciplinary group of experts from professional medical societies. The consensus on recommendations and statements was achieved in a structured consensus process. Method The current guideline is based on the expired S1-guideline, which was updated by a systematic search of the literature and a review of relevant publications issued between February 2014 and March 2019. Statements were compiled and voted on by a panel of experts. Recommendations The guideline provides general and specific recommendations on the prevention, diagnosis and treatment of positioning injuries.

Hormonal Contraception. Guideline of the DGGG, OEGGG and SGGG (S3 Level, AWMF Registry Number 015/015, January 2020)

Aims This is an official interdisciplinary guideline published and coordinated by the German Society for Gynecology and Obstetrics (DGGG), the Austrian Society for Gynecology and Obstetrics (OEGGG) and the Swiss Society for Gynecology and Obstetrics (SGGG). The guideline was developed for use in German-speaking regions and is backed by numerous professional societies and organizations. The aim of this guideline is to provide an evidence- and consensus-based overview of the diagnostic approach and the management of hormonal contraception based on a systematic evaluation of the relevant literature. Methods To compile this S3-guideline, a systematic search for evidence was carried out in PubMed and the Cochrane Library to adapt existing guidelines and identify relevant reviews and meta-analyses. A structured evaluation of the evidence was subsequently carried out on behalf of the Guidelines Commission of the DGGG, and a structured consensus was achieved based on consensus conferences attended by representative members from the different specialist societies and professions. Recommendations Evidence-based recommendations about the advice given to women requesting contraception were compiled. The guideline particularly focuses on prescribing contraceptives which are appropriate to women's individual needs, take account of her personal circumstances, and have few or no side effects.

COVID-19-Induced ARDS Is Associated with Decreased Frequency of Activated Memory/Effector T Cells Expressing CD11a+

Preventing the progression to acute respiratory distress syndrome (ARDS) in COVID-19 is an unsolved challenge. The involvement of T cell immunity in this exacerbation remains unclear. To identify predictive markers of COVID-19 progress and outcome, we analyzed peripheral blood of 10 COVID-19-associated ARDS patients and 35 mild/moderate COVID-19 patients, not requiring intensive care. Using multi-parametric flow cytometry, we compared quantitative, phenotypic, and functional characteristics of circulating bulk immune cells, as well as SARS-CoV-2 S-protein-reactive T cells between the two groups. ARDS patients demonstrated significantly higher S-protein-reactive CD4+ and CD8+ T cells compared to non-ARDS patients. Of interest, comparison of circulating bulk T cells in ARDS patients to non-ARDS patients demonstrated decreased frequencies of CD4+ and CD8+ T cell subsets, with activated memory/effector T cells expressing tissue migration molecule CD11a++. Importantly, survival from ARDS (4/10) was accompanied by a recovery of the CD11a++ T cell subsets in peripheral blood. Conclusively, data on S-protein-reactive polyfunctional T cells indicate the ability of ARDS patients to generate antiviral protection. Furthermore, decreased frequencies of activated memory/effector T cells expressing tissue migratory molecule CD11a++ observed in circulation of ARDS patients might suggest their involvement in ARDS development and propose the CD11a-based immune signature as a possible prognostic marker.

Robust T Cell Response Toward Spike, Membrane, and Nucleocapsid SARS-CoV-2 Proteins Is Not Associated with Recovery in Critical COVID-19 Patients

T cell immunity toward SARS-CoV-2 spike (S-), membrane (M-), and nucleocapsid (N-) proteins may define COVID-19 severity. Therefore, we compare the SARS-CoV-2-reactive T cell responses in moderate, severe, and critical COVID-19 patients and unexposed donors. Overlapping peptide pools of all three proteins induce SARS-CoV-2-reactive T cell response with dominance of CD4+ over CD8+ T cells and demonstrate interindividual immunity against the three proteins. M-protein induces the highest frequencies of CD4+ T cells, suggesting its relevance for diagnosis and vaccination. The T cell response of critical COVID-19 patients is robust and comparable or even superior to non-critical patients. Virus clearance and COVID-19 survival are not associated with either SARS-CoV-2 T cell kinetics or magnitude of T cell responses, respectively. Thus, our data do not support the hypothesis of insufficient SARS-CoV-2-reactive immunity in critical COVID-19. Conversely, it indicates that activation of differentiated memory effector T cells could cause hyperreactivity and immunopathogenesis in critical patients.

Tamoxifen and Endometrial Cancer: A Janus-Headed Drug

Simple Summary

Tamoxifen, an antiestrogen, is a potent drug to treat and prevent hormone dependent breast cancer. As it has low toxicity and is widely available, tamoxifen has become one of the most frequently prescribed anticancer drugs worldwide. A major side effect of tamoxifen is to increase the risk of uterine corpus cancer (endometrial cancer). This happens after long-term (>2 years) application, especially in postmenopausal women with preexisting pathologies in the uterus. On the other hand, tamoxifen is an efficacious treatment for certain forms of advanced endometrial cancer, thus making it a Janus-headed drug that can support the development of endometrial cancer on one hand and be used as a remedy for this disease on the other. This article reviews the clinical data on these controversial effects of tamoxifen and the possible explanations.

Abstract

Tamoxifen is a selective estrogen receptor modulator used for the treatment and prevention of estrogen receptor (ER)—positive breast cancer. However, tamoxifen increases the risk of endometrial cancer (EC) by about 2–7 fold, and more aggressive types of EC with poor prognoses are observed in tamoxifen users. On the other hand, tamoxifen is an efficacious treatment for advanced or recurrent EC with low toxicity. The differential agonistic or antagonistic effects of tamoxifen on ERα are explained by the tissue-specific expression profiles of co-activators and co-repressors of the receptor. The estrogen-agonistic effect of tamoxifen in endometrial cancers can also be explained by the expression of G-protein coupled estrogen receptor 1 (GPER-1), a membrane-bound estrogen receptor for which tamoxifen and other “antiestrogens” are pure agonists.

Peri- and postmenopause-diagnosis and interventions interdisciplinary S3 guideline of the association of the scientific medical societies in Germany (AWMF 015/062): short version

This short version of the interdisciplinary S3 guideline "Peri- and Postmenopause-Diagnosis and Interventions" is intended as a decision-making instrument for physicians who counsel peri- and postmenopausal women. It is designed to assist daily practice. The present short version summarizes the full version of the guideline which contains detailed information on guideline methodology, particularly regarding the critical appraisal of the evidence and the assignment of evidence levels. The statements and recommendations of the full version of the guideline are quoted completely in the present short version including levels of evidence (LoE) and grades of recommendation. The classification system developed by the Centre for Evidence-based Medicine in Oxford was used in this guideline.

Genetic Susceptibility to Endometrial Cancer: Risk Factors and Clinical Management

Endometrial cancer (EC) is the most common cancer affecting the female reproductive organs in higher-income states. Apart from reproductive factors and excess weight, genetic predisposition is increasingly recognized as a major factor in endometrial cancer risk. Endometrial cancer is genetically heterogeneous: while a subgroup of patients belongs to cancer predisposition syndromes (most notably the Lynch Syndrome) with high to intermediate lifetime risks, there are also several common genomic polymorphisms contributing to the spectrum of germline predispositions. Germline variants and somatic events may act in concert to modulate the molecular evolution of the tumor, where mismatch-repair deficiency is common in endometrioid endometrial tumors whereas homologous recombinational repair deficiency has been described for non-endometrioid endometrial tumors. In this review, we will survey the currently known genomic predispositions for endometrial cancer and discuss their relevance for clinical management in terms of counseling, screening and novel treatments.

Statement of the AGO and AG-CPC on the Aftercare/Follow-up for Surgical Procedures of the Lower Genital Tract after the Introduction of a New Cancer Screening Guideline

The new guideline on organized cancer screening programs has been in force in Germany since January 1st, 2020. The guideline has amended earlier recommendations on cytological examinations, which were previously carried out annually during screening. The guidelines-based recommendations on the appropriate follow-up for preinvasive and invasive lesions of the uterine cervix and endometrium are briefly outlined and differentiated from screening cytology and Pap/HPV co-testing as described in the guideline on organized cancer screening programs (oKFE-RL).

Adjuvant Radiotherapy and/or Chemotherapy for Endometrial Cancer, Status as at 2019: Opinion of the Uterus Commission of the Gynecological Oncology Working Group (AGO)

The role of adjuvant radiotherapy and/or chemotherapy in the primary treatment of endometrial cancer with a high risk of recurrence has still not been conclusively determined. The results of 3 large randomized controlled studies on different aspects of this issue have been published in full in recent months, and the relevant results are analyzed here.

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.

Updated Opinion of the Uterus Commission of the Gynecological Oncology Working Group (AGO) and the Gynecological Endoscopy Working Group (AGE) of the German Society of Gynecology and Obstetrics (DGGG) on the Randomized Study Comparing Minimally Invasive with Abdominal Radical Hysterectomy for Early-stage Cervical Cancer (LACC)

In this opinion on the randomized study comparing minimally invasive with abdominal radical hysterectomy for early-stage cervical cancer (LACC), the Uterus Commission of the Gynecological Oncology Working Group (AGO) and the Gynecological Endoscopy Working Group (AGE) of the Germany Society of Gynecology and Obstetrics (DGGG) state that, based on their examination of the published data, patients with FIGO stage IA1 (with LVSI), IA2 or IB1 cervical cancer must be informed about the results of this LACC study prior to making a decision on the route for radical hysterectomy.

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.

Interdisciplinary Diagnosis, Therapy and Follow-up of Patients with Endometrial Cancer. Guideline (S3-Level, AWMF Registry Number 032/034-OL, April 2018) - Part 2 with Recommendations on the Therapy and Follow-up of Endometrial Cancer, Palliative Care, Psycho-oncological/Psychosocial Care/Rehabilitation/Patient Information and Healthcare Facilities

Summary The first German interdisciplinary S3-guideline on the diagnosis, therapy and follow-up of patients with endometrial cancer was published in April 2018. Funded by German Cancer Aid as part of an Oncology Guidelines Program, the lead coordinators of the guideline were the German Society of Gynecology and Obstetrics (DGGG) and the Gynecological Oncology Working Group (AGO) of the German Cancer Society (DKG). Purpose Using evidence-based, risk-adapted therapy to treat low-risk women with endometrial cancer avoids unnecessarily radical surgery and non-useful adjuvant radiotherapy and/or chemotherapy. This can significantly reduce therapy-induced morbidity and improve the patient's quality of life as well as avoiding unnecessary costs. For women with endometrial cancer and a high risk of recurrence, the guideline defines the optimal extent of surgical radicality together with the appropriate chemotherapy and/or adjuvant radiotherapy if required. An evidence-based optimal use of different therapeutic modalities should improve the survival rates and quality of life of these patients. This S3-guideline on endometrial cancer is intended as a basis for certified gynecological cancer centers. The aim is that the quality indicators established in this guideline will be incorporated in the certification processes of these centers. Methods The guideline was compiled in accordance with the requirements for S3-level guidelines. This includes, in the first instance, the adaptation of source guidelines selected using the DELBI instrument for appraising guidelines. Other consulted sources included reviews of evidence, which were compiled from literature selected during systematic searches of literature databases using the PICO scheme. In addition, an external biostatistics institute was commissioned to carry out a systematic search and assessment of the literature for one part of the guideline. Identified materials were used by the interdisciplinary working groups to develop suggestions for Recommendations and Statements, which were then subsequently modified during structured consensus conferences and/or additionally amended online using the DELPHI method, with consent between members achieved online. The guideline report is freely available online. Recommendations Part 2 of this short version of the guideline presents recommendations for the therapy of endometrial cancer including precancers and early endometrial cancer as well as recommendations on palliative medicine, psycho-oncology, rehabilitation, patient information and healthcare facilities to treat endometrial cancer. The management of precancers of early endometrial precancerous conditions including fertility-preserving strategies is presented. The concept used for surgical primary therapy of endometrial cancer is described. Radiotherapy and adjuvant medical therapy to treat endometrial cancer and uterine carcinosarcomas are described. Recommendations are given for the follow-up care of endometrial cancer, recurrence and metastasis. Palliative medicine, psycho-oncology including psychosocial care, and patient information and rehabilitation are presented. Finally, the care algorithm and quality assurance steps for the diagnosis, therapy and follow-up of patients with endometrial cancer are outlined.

Statement of the Uterus Committee of the Gynaecological Oncology Working Group (AGO) on the PORTEC-3 study

The data on the adjuvant therapy of endometrial cancer (EC) are inconsistent. Recent studies of this topic such as PORTEC-3, GOG-258 and GOG-249 investigated the value of adjuvant radiotherapy, adjuvant chemotherapy and combined adjuvant chemoradiotherapy followed by chemotherapy in patients with endometrial cancer and an increased risk of recurrence. With this statement, the Uterus Committee of the Gynaecological Oncology Working Group (AGO) wishes therefore to interpret the new data and discuss them against the background of the new S3 guideline “Diagnosis, treatment and follow-up of patients with endometrial cancer”.

Interdisciplinary Diagnosis, Therapy and Follow-up of Patients with Endometrial Cancer. Guideline (S3-Level, AWMF Registry Nummer 032/034-OL, April 2018) - Part 1 with Recommendations on the Epidemiology, Screening, Diagnosis and Hereditary Factors of Endometrial Cancer

PIPAC-OV3: A multicenter, open-label, randomized, two-arm phase III trial of the effect on progression-free survival of cisplatin and doxorubicin as Pressurized Intra-Peritoneal Aerosol Chemotherapy (PIPAC) vs. chemotherapy alone in patients with platinum-resistant recurrent epithelial ovarian, fallopian tube or primary peritoneal cancer

Background

Recurrent, platin-resistant ovarian cancer (rPROC) has a poor survival. Even with the AURELIA trial, which is the best available treatment today, progression-free survival (PFS) is still only 6.7 months from the start of the second-line chemotherapy. Innovative, effective therapies are urgently needed. Pressurized Intra-Peritoneal Aerosol Chemotherapy (PIPAC) is a novel drug delivery system for administering drugs into the abdomen. PIPAC with cisplatin and doxorubicin (PIPAC C/D) may be safely used at an intraperitoneal dose of 10.5 mg/m² and 2.1 mg/m², respectively. Systemic toxicity of this therapy is low. In a phase II trial with 53 women, 62 % patients had an objective tumor response. Tumor regression on histology was observed in 76 % patients who underwent all three PIPACs. Randomized phase III studies are now required to evaluate the effect of PIPAC C/D compared to other standard treatments (sequential or simultaneous applications with systemic chemotherapy).

Methods

The present phase III study is a prospective, open, randomized, multicentric pivotal trial. A total of 244 patients will be randomly assigned (1:1) to the control (A) or to the experimental (B) group. Group A: Systemic palliative chemotherapy, physician’s best choice (monotherapy consisting of pegylated liposomal doxorubicin or topotecan or gemcitabine or paclitaxel weekly. Bevacizumab can be used in combination with paclitaxel, topotecan, or pegylated liposomal doxorubicin). Group B: Intraperitoneal chemotherapy, 3×PIPAC C/D, performed every 6 weeks. Combination with systemic therapy is not allowed. Treatment is continued until disease progression, death, or patient refusal. In case of progression, no recommendation for further therapy is given by protocol. Patients are allowed to receive PIPAC C/D or systemic chemotherapy after study termination. The primary endpoint is PFS (according to RECIST v1.1) or death from any cause. The co-primary endpoint is the health-related quality of life (HRQoL) measured as the global health status (GHS, QLQ-30 of EORTC). Secondary outcomes comprise overall survival, safety (CTCAE 5.0), and tumor response according to peritoneal regression grading score (PRGS).

Discussion

We expect PIPAC C/D to control peritoneal disease and preserve the QoL on this subset of patients.

Pressurized intraperitoneal aerosol chemotherapy (PIPAC) for peritoneal carcinomatosis: systematic review of clinical and experimental evidence with special emphasis on ovarian cancer

BACKGROUND

Systemic chemotherapy is not effective in patients with peritoneal carcinomatosis (PC) and only a minority of affected patients is eligible for cytoreductive surgery. Intraperitoneal chemotherapy may provide a therapy alternative for these patients.

METHODS

We performed a systematic review of clinical and experimental evidence on the safety and efficacy of pressurized intraperitoneal aerosol chemotherapy (PIPAC) in patients with PC and provide clinical recommendations based on the available evidence.

RESULTS

Fifty-eight reports were identified, categorized as experimental (18 reports), clinical (28 reports), and other articles (14 reports). Experimental studies demonstrated improved tissue penetration and peritoneal coverage. The 28 clinical studies reported on 3515 procedures in 1547 patients with PC of various primary tumors with 16 of these studies reporting on patients with ovarian cancer. Toxicity was manageable. Based on 1197 patients in 22 studies, adverse events CTCAE grades 1, 2, 3, 4, and 5 were observed in 537 (45%), 167 (14%), 83 (7%), 10 (0.8%), and 19 (1.6%) cases, respectively. In a pooled analysis, the objective tumor response rate was 69% and the mean overall survival duration was 13.7 months. No significant hepatic, renal, or hematologic toxicity was described. PIPAC maintained and/or improved quality of life, as reported in 10 studies with 396 patients.

CONCLUSIONS

Available evidence from controlled trials (phase I and phase II) and retrospective cohort studies in > 1500 patients unequivocally demonstrates that PIPAC is feasible, safe, and effective. PIPAC maintains quality of life in patients with recurrent cancer and PC. PIPAC is as evidence-based as any other treatment in women with ovarian cancer and PC beyond the third line of systemic chemotherapy and can be recommended in this indication.

Pressurized intraperitoneal aerosol chemotherapy (PIPAC) in combination with standard of care chemotherapy in primarily untreated chemo naïve upper gi-adenocarcinomas with peritoneal seeding - a phase II/III trial of the AIO/CAOGI/ACO

BACKGROUND

Peritoneal metastasis is a common and dismal evolution of several gastrointestinal (GI) tumors, including gastric, colorectal, hepatobiliary, pancreatic, and other cancers. The therapy of peritoneal metastasis is largely palliative; with the aim of prolonging life and preserving its quality. In the meantime, a significant pharmacological advantage of intraperitoneal chemotherapy was documented in the preclinical model, and numerous clinical studies have delivered promising clinical results.

METHODS

This is a prospective, open, randomized multicenter phase III clinical study with two arms that aims to evaluate the effects of pressurized intraperitoneal aerosol chemotherapy (PIPAC) combined with systemic chemotherapy vs. intravenous systemic chemotherapy alone on patients with metastatic upper GI tumors with a peritoneal seeding. Upper GI-adenocarcinomas originated from biliary tract, pancreas and stomach, or esophago- gastric junction are eligible. Patients in the study are treated with standard of care systemic palliative chemotherapy (mFOLFOX6) vs. PIPAC with intravenous (i.v.) chemotherapy (mFOLFOX6). Patients in first line with first diagnosed peritoneal seeding are eligible. Primary outcome is progression free survival (PFS).

CONCLUSIONS

PIPAC-procedure is explicit a palliative method but it delivers cytotoxic therapy like in hyperthermic intraperitoneal chemotherapy (HIPEC)-procedure directly to the tumor in a minimally invasive technique, without the need for consideration of the peritoneal-plasma barrier. The technique of PIPAC is minimally invasive and very gentle and the complete procedure takes only round about 45 min and, therefore, optimal in a clearly palliative situation where cure is not the goal. It is also ideal for using this approach in a first line situation, where deepest response should be achieved. The symbiosis of systemic therapy and potentially effective surgery has to be well-planned without deterioration of the patient due to aggressive way of surgery like in cytoreductive surgery (CRS)+HIPEC.

A Distinct Oncogenerative Multinucleated Cancer Cell Serves as a Source of Stemness and Tumor Heterogeneity

The effects of anticancer treatments on cell heterogeneity and their proliferative potential play an important role in tumor persistence and metastasis. However, little is known about de-polyploidization, cell fate, and physiologic stemness of the resulting cell populations. Here, we describe a distinctive cell type termed "pregnant" P1 cells found within chemotherapy-refractory ovarian tumors, which generate and gestate daughter generation Gn cells intracytoplasmically. Release of Gn cells occurred by ejection through crevices in the P1 cell membrane by body contractions or using a funiculus-like structure. These events characterized a not yet described mechanism of cell segregation. Maternal P1 cells were principally capable of surviving parturition events and continued to breed and nurture Gn progenies. In addition, P1 cells were competent to horizontally transmit offspring Gn cells into other specific proximal cells, injecting them to receptor R1 cells via cell-cell tunneling. This process represents a new mechanism used by tumor cells to invade surrounding tissues and ensure life cycles. In contrast to the pregnant P1 cells with low expression of stem cell markers despite their physiologic stemness, the first offspring generations of daughter G1 cells expressed high levels of ovarian cancer stem cell markers. Furthermore, both P1 and Gn cells overexpressed multiple human endogenous retroviral envelope proteins. Moreover, programmed death-ligand 1 and the immunosuppressive domain of the retroviral envelope proteins were also overexpressed in P1 cells, suggesting effective protection against the host immune system. Together, our data suggest that P1 oncogenerative cancer cells exhibit a not yet described cell biological mechanism of persistence and transmission of malignant cells in patients with advanced cancers.Significance: P1 oncogenerative cell entities express low levels of CSC markers, which are characteristic of their histological origin.

Recurrent Miscarriage: Diagnostic and Therapeutic Procedures. Guideline of the DGGG, OEGGG and SGGG (S2k-Level, AWMF Registry Number 015/050)

Purpose

Official guideline of the German Society of Gynecology and Obstetrics (DGGG), the Austrian Society of Gynecology and Obstetrics (ÖGGG) and the Swiss Society of Gynecology and Obstetrics (SGGG). The aim of this guideline was to standardize the diagnosis and treatment of couples with recurrent miscarriage (RM). Recommendations were based on the current literature and the views of the involved committee members.

Methods

Based on the current literature, the committee members developed the statements and recommendations of this guideline in a formalized process which included DELPHI rounds and a formal consensus meeting.

Recommendations

Recommendations for the diagnosis and treatment of patients with RM were compiled based on the international literature. Specific established risk factors such as chromosomal, anatomical, endocrine, hemostatic, psychological, infectious and immunological disorders were taken into consideration.

[Comparison of International Guidelines For the Application of Cardiotocography]

OBJECTIVE

This study examines the recommendations of international guidelines on the use of antepartum and intrapartum cardiotocography.

MATERIAL AND METHODS

The guidelines of Germany, Canada, UK, USA, Sri Lanka, Australia as well as FIGO have been compared. The recommendations on the use of cardiotocography were separately evaluated for antepartum and intrapartum use.

RESULTS

Antepartum: In risk-free pregnancies the use of cardiotocography is not recommended in all countries. On the other hand the use of cardiotocography is indicated in the presence of a defined maternal and fetal risk factors. While the NICE guidelines recommend cardiotocography in the case of maternal hypertension, as well as preeclampsia, the German guidelines as well as SOGC list considerably more risk factors. Intrapartually, the recommendations vary greatly from country to country. While German guidelines suggest the use of cardiotocography from late 1st stage of labor, the other countries strongly recommend the auscultation of the fetal heart rate of non-risk pregnancies. This is due to the current study situation, which does not show any advantage of cardiotocography as opposed to intermittent auscultation. Furthermore studies have indicated that the use of cardiotocography caused an increase in iatrogenic induced cesarean sections. In high risk pregnancies the use of cardiotocography is strongly recommended in the compared countries, however there are major differences in the definition of high risk pregnancy and therefore the indication for cardiotocographic monitoring.

CONCLUSION

Intermittent auscultation is a more cost-effective alternative compared to cardiotocography. However, in the case of legal litigation intermittent auscultation is harder to reconstruct the well-being of the newborn during birth. On the other hand cardiotocography might result in a higher cesarean section rate, but can be more helpful to prove fetal well-being during birth for a legal litigation process. Despite the lack of evidence only German guidelines recommend cardiotocographic monitoring from the late 1st stage of labor for risk-free pregnancies.

A collagen-fibrin patch for the prevention of symptomatic lymphoceles after pelvic lymphadenectomy in women with gynecologic malignancies: A randomized clinical trial

OBJECTIVE

To evaluate the efficacy of a collagen-fibrin patch for the prevention of symptomatic lymphoceles after pelvic lymphadenectomy in women with gynecologic malignancies.

METHODS

In a multicenter, randomized, clinical trial, 164 women with pelvic lymphadenectomy were allocated either to bilateral pelvic application of two collagen-fibrin patches or no intervention. Main outcome was efficacy, defined as reduction of symptomatic lymphocele rate diagnosed within four weeks after surgery. Secondary outcomes were asymptomatic lymphoceles and subsequent interventions. Sample size was based on the assumption that application of a collagen-fibrin patch reduces the prevalence of symptomatic lymphoceles by at least 66%. The study was single-blinded, i.e., patients and primary outcome assessors, but not surgeons, were blinded to the treatment allocation.

RESULTS

A total of 75 women were randomized to the intervention and 89 to the control group. All women received the allocated intervention. In total, 42 (27.4%) lymphoceles and 8 (5.2%) symptomatic lymphoceles were observed. Symptomatic lymphoceles were observed in 5/68 (7.4%) women in the intervention group and 3/85 (3.5%) women in the control group (p = 0.47). Asymptomatic lymphoceles were observed in 16 (23.5%) women in the intervention group compared to 18 (21.2%) in the control group (p = 0.85). In a multivariate logistic regression model, no independent risk factor for the development of a symptomatic lymphocele was ascertained.

DISCUSSION

Intraoperative application of collagen-fibrin patches to the pelvic side walls does not reduce the incidence of symptomatic lymphoceles in women with gynecologic malignancies undergoing pelvic lymphadenectomy.

Serologic markers of autoimmunity in women with recurrent pregnancy loss

PROBLEM

Various autoimmunologic mechanisms have been shown to be involved in recurrent pregnancy loss (RPL). This study aimed to evaluate whether women with RPL have elevated serum levels of common autoimmunologic parameters.

METHOD OF STUDY

Serum levels of antinuclear antibodies (ANAs) were measured in 114 women with RPL, and 107 healthy controls using a qualitative immunometric enzyme immunoassay, serum levels of IgG class autoantibodies against histone, IgG class autoantibodies against nucleosomes, and IgG class autoantibodies against double-stranded (ds) DNA were measured by quantitative enzyme immunoassays.

RESULTS

No differences were ascertained regarding serum levels of ANAs (P=.9), serum levels of antibodies against histones (P=.1), antibodies against nucleosomes (P=.4) and antibodies against dsDNA (P=.6) between women with RPL and healthy controls. No associations were found between serum levels and clinical characteristics of affected women.

CONCLUSION

Our study shows that serologic parameters of autoimmunity are not elevated in women with RPL and are not associated with clinical characteristics of affected women.

Pressurized intraperitoneal aerosol chemotherapy (PIPAC) as a neoadjuvant therapy before cytoreductive surgery and hyperthermic intraperitoneal chemotherapy

BACKGROUND

Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is a novel drug delivery system able to induce regression of peritoneal metastasis (PM) in the salvage situation. The aim of this study was to determine the clinical characteristics, tumor histology, and extent of disease of the patients having undergone cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) after "neoadjuvant" PIPAC.

METHODS

This study was performed at a single institution, tertiary center. In a prospective registry, retrospective analysis was done. PIPAC indication was restricted to patients in the salvage situation who were not eligible for cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC).

RESULTS

Nine-hundred sixty-one PIPAC sessions were successfully performed in 406 patients: 21 patients (5.2 %) were scheduled for CRS and HIPEC. Twelve of these patients had a low PCI (mean 5.8 ± 5.6). The remaining nine patients showed an advanced peritoneal disease (mean PCI 14.3 ± 5.3) at initial laparoscopy. After repeated PIPAC (mean number of cycles 3.5 ± 0.9), radiological tumor regression was observed in 7/9 patients and major histological regression was observed in 8/9 patients, so that secondary CRS and HIPEC became possible.

CONCLUSIONS

PIPAC might be used as a neoadjuvant therapy before CRS and HIPEC in order to improve the outcome of CRS and HIPEC, to select patients with chemosensitive, biologically favorable tumors, to extent the indications of CRS and HIPEC in the presence of diffuse small bowel involvement, and to reduce the extent of cytoreductive surgery.
