Vision Development of guidelines and quality indicators is one of the core activities of the European Society of Gynaecological Oncology (ESGO), as part of ESGO's mission to improve the quality of care for women with gynaecological cancers across Europe. Recommendations for treatment of Endometrial, Cervical, Ovarian and Vulvar Cancer as well as Ovarian Cancer Quality Indicators are available and an easy-to-use mobile App has been developed for your daily practice. ESGO has set an objective to elaborate a complete set of guidelines and associated quality indicators for the management of gynaecological cancers, in effort to improve the quality of care for women across Europe, as part of ESGO's mission statement. Strict standards, including a proper methodology, a systematic literature search, internal and external reviews of the final document, including participation of patients’ representatives have been adopted to ensure the production of high-quality guidelines and quality indicators. Whenever relevant and possible, the ESGO tries to associate the relevant sister knowledgeable societies such as ESMO, ESTRO, ESP, ISUOG, ESGE, SIOPE and others. With its national partners and collaborators, ESGO initiated the translation of the guidelines and quality indicators into national languages that are available on the website for broad use in clinical practice. In the spirit of making the guidelines and quality indicators as user-friendly as possible, ESGO has developed the mobile application for both Android and iOS phones. The user friendly navigation throughout the application enables users an easy and quick access to the required information, to support decision making at the point of care. We hope that European gynaecologic oncologists – and non-European colleagues as well – will find the recommendations and quality indicators helpful in achieving high quality cancer management and reliable assurance of the quality of surgery across Europe. Methodology The ESGO guidelines are developed using a six-step process. The strengths of the process include: 1) definition of the project, 2) nomination of a multidisciplinary international development group, 3) systematic independent literature review by the ESGO methodologist, 4) formulation of recommendations, 5) use of an external review process (international validation by physicians and patients), 6) integration of international reviewer`s comments. This development process involves at least one physical meetings of an international development group. ESGO Algorithms App Get started and download the ESGO Algorithms App!
