    Fertility-sparing in cancer patients

    Objective: This review aimed to investigate and summarize the current evidence on fertility-sparing options in cancer patients. Mechanism: Fertility preservation methods are becoming popular through the improved prognosis of cancer patients at a younger age and early diagnostic tools. However, currently, more and more women are suffering from iatrogenic ovarian failure and fertility loss because of cancer treatment. Most treatments have been used for hematological malignancies, but different gynecological cancers can be eligible. Findings in brief: Fertility preserving strategies such as oocyte and embryo cryopreservation, ovarian tissue preservation, ovarian transposition, and aspiration of ovarian follicles are the methods that could be suggestedto the patients. The current knowledge supports oocyte and embryo cryopreservation as feasible, safe, and effective treatment approaches for cancer patients seeking fertility preservation. Conclusions: Robust evidence is still needed to prove the effectiveness of cryopreservation of the ovarian tissue and ovarian follicle aspiration approaches since these techniques are still in early their steps.

    The importance of dysregulated miRNAs on ovarian cysts and epithelial ovarian cancer

    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.
