    Conservative surgery has long been discussed as a treatment option in women with ovarian cancer at reproductive age. However, current guidelines recommend conservative surgery only in selected patients. There is considerable interest on pregnancy and delivery rates after fertility-sparing surgery (FSS), with several ongoing studies on this subject. The aim of the present multi-center study was to evaluate survival and pregnancy outcomes in patients that underwent fertility-sparing surgery. This retrospective study included 19 patients who underwent fertility-sparing surgery due to invasive epithelial ovarian cancer between 2002 and 2014. The median duration of follow-up was 59.5 months (range 10-152 months). A total of 10 full-term pregnancies and 3 spontaneous abortions occurred in 7 patients (36.8\%) following FSS. Ten patients (52.6\%) underwent prophylactic surgery after a median period of 49 months (16-119 months), while 2 patients (10.5\%) developed recurrent disease after prophylactic surgery. Accurate staging in patients with early stage epithelial ovarian cancer and regular follow-up has shown promising reproductive outcomes. In light of the current data, fertility-sparing surgery should be considered in selected patients with stage I epithelial ovarian cancer. There is still no consensus, however, on the selection criteria of eligible patients for fertility-sparing surgery.

    Objective: Benign ovarian cysts (BOC) are the most common tumors in women of reproductive age. Usually, these cysts are harmless, but, a small number of them occasionally progress to malignancy. Among ovarian malignancies, epithelial ovarian cancer (EOC) comprises 90\% and is the most important cause of gynecologic cancerrelated deaths. We aimed to identify dysregulated miRNAs in patients with benign ovarian cysts (n = 11) compared to EOC (n = 10) and to healthy individuals (HI) (n = 15). Methods: The serum samples from EOC and BOC patients were collected before operation. We studied three different sample groups (serum of EOC (n = 8), HI (n = 8), and BOC (n = 8) patients) that contained the highest-quality of RNA. Microarray data were analyzed according to expression of miRNAs and target genes by bioinformatics tools. Results: When compared to EOC samples, 75 miRNAs were dysregulated in BOC samples. Sixty-six miRNAs from BOC were dysregulated when compared to HI samples. Bioinformatics analysis of BOC vs. EOC and BOC vs. HI showed that 46 miRNAs were congruent and their expression alterations were similar (up- or down-regulated). Further analysis showed that these 46 miRNAs are associated to one of three pathways involved in cancer pathogenesis. Conclusion: Several miRNAs might playa role in BOC formation and/or malignant transformation. These dysregulated miRNAs could potentially be a biomarker to distinguish between a completely BOC and one that is malignant or has potential for malignant transformation.
