Purpose: To investigate whether CD73 had a role in the pathogenesis of polypoid endometriosis., Methods: Our study included 15 cases of polypoid endometriosis, which were diagnosed between 2005 and 2019. Clinical findings were gathered from archive files of relevant clinics and pathology reports. All glass slides were re-examined for confirmation of the diagnosis and the detection of additional microscopic findings. An immunohistochemical examination was performed using anti CD73 antibodies in 15 cases of polypoid endometriosis, and also in a control group that contained 9 cases of endometrial polyps and 9 cases of ovarian conventional endometriosis., Results: In addition to standard gynecologic operations, major non-gynecologic procedures had to be performed in 7 cases. In two cases, the surgical team comprised only general surgeons, and a misdiagnosis of carcinoma was made during the frozen section in one case. The majority of the cases displayed gross polypoid lesions that measured 0.7-13 cm. The most common sites were the ovary and rectosigmoid colon. Microscopically, all lesions exhibited a fibrovascular stroma reminiscent of endometrial stroma, whereas glandular features varied. Immunohistochemical examinations revealed a significant loss of CD73 expression in the stroma of polypoid endometriosis in contrast to the control cases, which retained stromal CD73 expression (p < 0.0001)., Conclusion: Both pathologists and surgeons performing abdominal surgeries should be aware of polypoid endometriosis because it mimics malignancy with its clinical, gross, and microscopic features. We also conclude that loss of stromal CD73 expression, due to its effect on the extracellular ATP/adenosine balance, may contribute to the pathogenesis of this rare form of endometriosis.

Purpose: Ovarian cancer (OC) is first gynaecologic cancer that causes women death and epithelial ovarian cancer (EOC) is the most lethal ovarian cancer type. While treatment is commonly successful, some cases (10-20%) show resistance to chemotherapy which is followed by recurrence. MicroRNA (miRNA) based diagnosis methods are slightly important for recurrent ovarian cancer diagnosis. We aimed to detect novel circulating miRNAs to be used as an early diagnosis and prediction tools for recurrent EOC., Methods: In this study, recurrent EOC serum samples and healthy control serum samples were compared for miRNA expression analysis by microarray. Microarray results were analyzed by bioinformatics tools and differentially expressed hsa-miR-1273g-3p was obtained. After microarray analysis, differentially expressed hsa-miR-1273g-3p was validated by Real-Time PCR (RT-qPCR). The relation between target genes of hsa-miR-1273g-3p and ovarian cancer were examined by Pathway Studio ® (v.11.4.0.8)., Results: The expression of hsa-miR-1273g-3p was found to be significantly down-regulated by t test Bonferroni FWER corrected p < 0.05 and fold change > 2, in recurrence EOC compare with healthy controls groups. The RT-qPCR results confirmed that relative expressions of the serum hsa-miR-1273g-3p were significantly down-regulated in patients with recurrent EOC (p = 0.0275). Serum hsa-miR-1273g-3p levels could discriminate patients with recurrent EOC from healthy controls, with a power area under the curve (AUC) of 0.7., Conclusion: This study suggested that hsa-miR-1273g-3p plays a significant role in regulation of related genes, which are TNF-alfa, COL1A1, MMP-2, MMP-9, with recurrent EOC outcome. hsa-miR-1273g-3p may be used as a prognostic marker for recurrent EOC after chemotherapy.

Purpose: To investigate clinicopathological characteristics and oncological outcome of women with microinvasive BOTs., Methods: A retrospective multicenter case-control study was conducted on 902 patients with BOT, who underwent surgery from January 2002 to December 2015 at six participating gynecologic oncology centers from Turkey. Among 902 patients, 69 had microinvasive BOT. For every patient with microinvasive BOT, two controls were randomly selected from another database based on decade of age and stage of disease at diagnosis. The clinical-pathological characteristics and oncological outcomes were compared between BOT patients with and without stromal microinvasion. Risk factors for poor oncological outcomes were investigated in a multivariate analysis model. Overall survival (OS) and disease-free survival (DFS) were estimated using the Kaplan-Meier method., Results: Patients with microinvasive BOT had a significantly higher rate of recurrence than patients without microinvasive BOT (17.4 vs 7.8%, OR 3.55, %95 CI 1.091-11.59, p = 0.03). Stage at diagnosis (stage I versus II/III) and type of surgery (cystectomy versus others) were found as other significant prognostic factors for recurrence in multivariate analysis (OR 8.63, %95 CI 2.48-29.9, p = 0.001 and OR 19.4, %95 CI 3.59-105.6, p = 0.001, respectively). Stromal microinvasion was found as a prognostic factor for significantly shorter DFS (26.7 vs 11.9 months, p = 0.031, log rank). However, there was no significant difference in OS between two groups (p = 0.99, log rank)., Conclusion: Stromal microinvasion is significantly associated with decreased DFS. In addition, our study confirms that the risk of recurrence is higher in patients with microinvasive BOT.

Acute colonic pseudo-obstruction is a rare complication of gynecological surgery. Despite the complete description of this condition, diagnosis remains difficult and is often delayed. Due to delay in diagnosis and existence of serious comorbid illnesses, morbidity and mortality approaches higher levels. Early recognition of signs and symptoms of this condition and prompt accurate management are vital to prevent serious mortality. Here, we report a case of acute colonic pseudo-obstruction after total abdominal hysterectomy in a patient with known Friedreich ataxia.

Objective: The objective was to determine whether therapeutic amniocentesis may improve outcomes in patients with twin-twin transfusion syndrome., Study Design: Eleven patients were managed aggressively with repetitive serial amniocenteses, and six patients were managed conservatively., Results: The time interval between diagnosis and delivery was 17.4 days more in the amniodrainage group, but the difference between the groups was not significant (68.3+/-41.9 days in the therapeutic amniocentesis group and 50.83+/-29.7 days in the expectant management group [p=0.384]). The overall survival rate of the two groups was 38.2%, and was not significantly different between groups (40.9% in the amniocentesis group and 33.3% in the expectant management group; p=1.00). Two of nine (22.2%) infants in the amnioreduction group, and one of four (25.0%) infants in the expectantly managed group had neurological symptoms., Conclusion: Our results did not show a significant benefit of aggressive therapeutic amniocentesis. A slight improvement in perinatal outcome was observed.
