- IntroductionWomen with cervical cancer in the Nordic countries are increasingly undergoing pretreatment imaging by ultrasound, magnetic resonance imaging (MRI), positron emission tomography-computed tomography (PET-CT) or computed tomography, or sentinel lymph node procedure. The present survey reports the influence of pretreatment imaging findings on the recorded clinical International Federation of Gynecology and Obstetrics (FIGO) stage in Nordic countries and its impact on treatment planning and preferred surgical approach in cervical cancer. Material and methodsThe Nordic Society of Gynecological Oncology Surgical Subcommittee developed a questionnaire-based survey that was conducted from 1 January to 31 March 2017. All the 22 Nordic Gynecological Oncology Centers (Denmark 5, Finland 5, Iceland 1, Norway 4, and Sweden 7) were invited to participate. ResultsThe questionnaires were returned by 19 of 22 (86.3%) centers. The median number (range) of women with cervical cancer treated at each center annually was 32 (15-120). In 58% (11/19) of the centers, imaging findings were reported to influence the clinical staging. MRI in combination with PET-CT was the preferred imaging method and the results influenced treatment planning. Robotic-assisted radical hysterectomy was the preferred surgical method in 72% (13/18) of the centers. Sentinel lymph node procedure was not routinely implemented in the majority of the Nordic centers. ConclusionMore than half of the Nordic Gynecological Oncology Centers already report a clinical FIGO stage influenced by pretreatment imaging findings. The trend in preferred treatment is robotic-assisted radical hysterectomy and the sentinel lymph node procedure is gradually being introduced.

- Introduction Human ovulation is a biologically complex process that involves several biochemical factors, promoting follicular rupture and release of a fertilizable oocyte. Proteins which are present in follicular fluid at high concentrations during ovulation are likely to be active participants in the biochemical pathways of ovulation. The aim of the study was to identify, by use of a modern proteomic technique, proteins of human follicular fluid which are differentially regulated during ovulation of the natural menstrual cycle. Material and methods This prospective experimental study over 3 years included women planned for laparoscopic sterilization. During surgery, retrieval of the dominant follicle was performed either at the preovulatory stage or during ovulation. Four women of preovulatory phase and four women of ovulatory phase met the predetermined criteria of hormone levels for respective phases, and samples of these were finally included out of the 15 women operated. Follicular fluid was aspirated from the excised follicle and subjected to mass spectrometry with the isobaric tags for relative and absolute quantification (iTRAQ) technology for isobaric tagging of peptides. This enables simultaneous identification and quantification of proteins. The protein profiles of the follicular fluid of the preovulatory phase and the ovulatory phase were analyzed, and proteins that were present were identified. Results A total of 502 proteins were identified, several of which previously have not been identified in human follicular fluid. Of the 115 proteins that were found in all samples, 20 proteins were at higher levels during ovulation. These were inflammatory-related proteins, coagulation factors, proteins in lipid metabolism, complement factors and antioxidants. Five proteins were present in lower levels during ovulation, with three being enzymes and the other two proteins of lipid metabolism and iron transport. Conclusions Twenty-five follicular fluid proteins, with differential regulation during ovulation, were identified in human follicular fluid of the natural menstrual cycle. These proteins may have essential roles in the ovulatory cascade.
