These consensus statements were developed by the European Society for Medical Oncology (ESMO) and the European Society of Gynaecological Oncology (ESGO) and are published jointly in the Annals of Oncology and the International Journal of Gynecological Cancer. The two societies nominated participants who attended the consensus conference and co-authored the final manuscript. ‡ See Appendix for members of the ESMO-ESGO Ovarian Cancer Consensus Conference Working Group. The development of guidelines recommendations is one of the core activities of the European Society for Medical Oncology (ESMO) and European Society of Gynaecologial Oncology (ESGO), as part of the mission of both societies to improve the quality of care for patients with cancer across Europe. ESMO and ESGO jointly developed clinically relevant and evidence-based recommendations in several selected areas in order to improve the quality of care for women with ovarian cancer. The ESMO-ESGO consensus conference on ovarian cancer was held on 12-14 April 2018 in Milan, Italy, and comprised a multidisciplinary panel of 40 leading experts in the management of ovarian cancer. Before the conference, the expert panel worked on five clinically relevant questions regarding ovarian cancer relating to each of the following four areas: pathology and molecular biology, early-stage and borderline tumours, advanced stage disease and recurrent disease. Relevant scientific literature, as identified using a systematic search, was reviewed in advance. During the consensus conference, the panel developed recommendations for each specific question and a consensus was reached. The recommendations presented here are thus based on the best available evidence and expert agreement. This article presents the recommendations of this ESMO-ESGO consensus conference, together with a summary of evidence supporting each recommendation.
Purpose: The forkhead box transcription factor FoxP3 is specifically expressed in T cells with regulatory properties (Treg). Recently, high numbers of Treg were described to be associated with poor survival in different malignancies. The aim of the presented study was determine the prognostic effect of FoxP3 mRNA expression (reflecting the tissue content of Treg) in ovarian carcinoma and its relation with cytokines, such as IFN-g. Experimental Design: Total RNA was isolated from 99 ovarian carcinoma and from 14 healthy ovarian biopsies. Real-time PCR for FoxP3 was done and correlated with IFN-g-, CD3-, IRF-1-, SOCS-1-, HER-2-, and iNOS expression as well as patients'outcome.The mRNA data was corroborated by FoxP3 immunohistochemistry. Results: Quantitation of FoxP3 expression identified a patient subgroup (>81th percentile), which is characterized by a significantly worse prognosis in terms of overall survival (27.8 versus 77.3 months, P = 0.0034) and progression-free survival (18 versus 57.5 months; P = 0.0041). FoxP3 expression correlated with IFN-g, IRF-1, and CD3 expression. High FoxP3 expression represents an independent prognostic factor for overall survival (P = 0.004) and progression-free survival (P = 0.004). Conclusions: High expression levels of FoxP3 might represent a surrogate marker for an immunosuppressive milieu contributing to tumor immune escape. Strategies selectively depleting Treg might improve the antitumor activity of endogenously arising tumor-reactiveTcells and immunotherapies using vaccines or antibodies.Cancer patients can harbor significant numbers of CD8 and CD4 T cells specific for tumor antigens. In most cases, tumorreactive T cells fail to eradicate the tumor in vivo because they seem to be actively maintained in an unresponsive state. Several immune-evasion strategies of malignant tumors have been described thus far (reviewed in ref. 1). Recently, regulatory T cells (Treg), which are characterized by coexpression of CD4 and CD25, have also been attributed to contribute to cancer-related immunosuppression (2 -5). Treg represent 5% to 10% of total CD4 + T cells and are crucial for the repression of autoimmune disorders and transplant rejection (6). The activation of Treg is antigen specific; however, inhibition of CD4 + and CD8 + T cells seems to be antigen nonspecific. Very recent evidence showed that Treg abrogate CD8 + T cell -mediated tumor rejection in a transforming growth factor-h -dependent manner (7). The suggestion of a role for Treg in cancer-induced immunosuppression in humans arises from the observation that patients suffering from a variety of cancer types have an enlarged pool of Treg in the peripheral blood, tumor-draining lymph nodes, and in the tumor itself (8 -12). Exact characterization of Treg has been hampered by the lack of specific cell surface markers. The observation that autoimmune diseases occur in both humans and mice lacking functional FoxP3 (13) indicates that this transcription factor plays a crucial role in the regulation of Treg function. ...
Peri-operative SARS-CoV-2 infection increases postoperative mortality. The aim of this study was to determine the optimal duration of planned delay before surgery in patients who have had SARS-CoV-2 infection. This international, multicentre, prospective cohort study included patients undergoing elective or emergency surgery during October 2020. Surgical patients with pre-operative SARS-CoV-2 infection were compared with those without previous SARS-CoV-2 infection. The primary outcome measure was 30-day postoperative mortality. Logistic regression models were used to calculate adjusted 30-day mortality rates stratified by time from diagnosis of SARS-CoV-2 infection to surgery. Among 140,231 patients (116 countries), 3127 patients (2.2%) had a pre-operative SARS-CoV-2 diagnosis. Adjusted 30-day mortality in patients without SARS-CoV-2 infection was 1.5% (95%CI 1.4-1.5). In patients with a pre-operative SARS-CoV-2 diagnosis, mortality was increased in patients having surgery within 0-2 weeks, 3-4 weeks and 5-6 weeks of the diagnosis (odds ratio (95%CI) 4.1 (3.3-4.8), 3.9 (2.6-5.1) and 3.6 (2.0-5.2), respectively). Surgery performed ≥ 7 weeks after SARS-CoV-2 diagnosis was associated with a similar mortality risk to baseline (odds ratio (95%CI) 1.5 (0.9-2.1)). After a ≥ 7 week delay in undertaking surgery following SARS-CoV-2 infection, patients with ongoing symptoms had a higher mortality than patients whose symptoms had resolved or who had been asymptomatic (6.0% (95%CI 3.2-8.7) vs. 2.4% (95%CI 1.4-3.4) vs. 1.3% (95%CI 0.6-2.0), respectively). Where possible, surgery should be delayed for at least 7 weeks following SARS-CoV-2 infection. Patients with ongoing symptoms ≥ 7 weeks from diagnosis may benefit from further delay.
To our knowledge, L1CAM has been shown to be the best-ever published prognostic factor in FIGO stage I, type I endometrial cancers and shows clear superiority over the standardly used multifactor risk score. L1CAM expression in type I cancers indicates the need for adjuvant treatment. This adhesion molecule might serve as a treatment target for the fully humanized anti-L1CAM antibody currently under development for clinical use.
