RESUMO
Postmenopausal bleeding (PMB) is a relevant aspect for health-care providers in clinical practice: the first objective is to rule out potential gynecological cancer. The purpose of this narrative review is to evaluate the role of office hysteroscopy in the management of PMB. Office hysteroscopy is a minimally invasive procedure allowing direct visualization of uterine pathology without the need for general anesthesia and the use of an operating room, generating cost savings and greater compliance among patients. Here, we focus on major intrauterine diseases (polyps, submucosal myomas, endometrial hyperplasia, and cancer) as causes of PMB. Office hysteroscopy appears to be safe and feasible, and could allow accurate diagnosis of intrauterine pathologies, especially that with a focal growth pattern, otherwise misdiagnosed with blinded procedures. However, studies focusing exclusively on postmenopausal women are still few, so further research, especially randomized controlled trials, is needed.

BACKGROUND: Several randomised controlled trials (RCTs) have investigated the usefulness of pituitary block with gonadotrophin-releasing hormone (GnRH) antagonists during intrauterine insemination (IUI) cycles, with conflicting results. OBJECTIVE: The aim of the present systematic review and meta-analysis of RCTs was to evaluate the effectiveness of GnRH antagonist administration as an intervention to improve the success of IUI cycles. SEARCH STRATEGY: Electronic databases (MEDLINE, Scopus, EMBASE, Sciencedirect) and clinical registers were searched from their inception until October 2017. SELECTION CRITERIA: Randomised controlled trials of infertile women undergoing one or more IUI stimulated cycles with GnRH antagonists compared with a control group. DATA COLLECTION AND ANALYSIS: The primary outcomes were ongoing pregnancy/live birth rate (OPR/LBR) and clinical pregnancy rate (CPR). Pooled results were expressed as odds ratio (OR) or mean differences with 95% confidence interval (95% CI). Sources of heterogeneity were investigated through sensitivity and subgroups analysis. The body of evidence was rated using GRADE methodology. Publication bias was assessed with funnel plot, Begg's and Egger's tests. MAIN RESULTS: Fifteen RCTs were included (3253 IUI cycles, 2345 participants). No differences in OPR/LBR (OR 1.14, 95% CI 0.82-1.57, P = 0.44) and CPR (OR 1.28, 95% CI 0.97-1.69, P = 0.08) were found. Sensitivity and subgroup analyses did not provide statistical changes in pooled results. The body of evidence was rated as low (GRADE 2/4). No publication bias was detected. CONCLUSION: Pituitary block with GnRH antagonists does not improve OPR/LBR and CPR in women undergoing IUI cycles. TWEETABLE ABSTRACT: Pituitary block with GnRH antagonists does not improve the success of IUI cycles.

OBJECTIVE: There is a growing body of evidence that suggests that the surgical technique for uterine closure following Cesarean delivery influences the healing of the Cesarean scar, but there is still no consensus on the optimal technique. The aim of this systematic review and meta-analysis was to compare the effect of single- vs double-layer uterine closure on the risk of uterine scar defect. METHODS: MEDLINE, Scopus, ClinicalTrials.gov, PROSPERO, EMBASE and the Cochrane Central Register of Controlled Trials were searched from inception of each database until May 2016. All randomized controlled trials (RCTs) evaluating the effect of single- vs double-layer uterine closure following low transverse Cesarean section on the risk of uterine scar defect were included. The primary outcome was the incidence of uterine scar defects detected on ultrasound. Secondary outcomes were residual myometrial thickness evaluated by ultrasound and the incidence of uterine dehiscence and/or rupture in subsequent pregnancy. Summary measures were reported as relative risk (RR) or mean difference (MD), with 95% CIs. Quality of the evidence was assessed using the GRADE approach. RESULTS: Nine RCTs (3969 participants) were included in the meta-analysis. The overall risk of bias of the included trials was low. Statistical heterogeneity within the studies was low, with no inconsistency in the primary and secondary outcomes. Women who received single-layer uterine closure had a similar incidence of uterine scar defects as did women who received double-layer closure (25% vs 43%; RR, 0.77 (95% CI, 0.36-1.64); five trials; 350 participants; low quality of evidence). Compared with double-layer uterine closure, women who received single-layer closure had a significantly thinner residual myometrium on ultrasound (MD, -2.19 mm (95% CI, -2.80 to -1.57 mm); four trials; 374 participants; low quality of evidence). No difference was found in the incidence of uterine dehiscence (0.4% vs 0.2%; RR, 1.34 (95% CI, 0.24-4.82); three trials; 3421 participants; low quality of evidence) or uterine rupture (0.1% vs 0.1%; RR, 0.52 (95% CI, 0.05-5.53); one trial; 3234 participants; low quality of evidence) in a subsequent pregnancy. CONCLUSIONS: Single- and double-layer closure of the uterine incision following Cesarean delivery are associated with a similar incidence of Cesarean scar defects, as well as uterine dehiscence and rupture in a subsequent pregnancy. However, the quality level of summary estimates, as assessed by GRADE, was low, indicating that the true effect may be, or is even likely to be, substantially different from the estimate of the effect.

OBJECTIVES: Lymphoceles are among the most common post-operative complications of pelvic lymphadenectomy, with a reported incidence of 1% to 29% in gynecology oncology. Several studies evaluated the effectiveness of biological glues on reducing lymphoceles, but no data on gynecological patients are available. We evaluated the effectiveness of cyanoacrylic glues (n-butyl cyanoacrylate) (Glubran 2 - GEM s.r.l., Italy) in preventing lymphocele on 30 patients who underwent pelvic lymphadenectomy for endometrial or cervical cancer. METHODS: Single-blind prospective randomized study. Patients were divided into 2 groups: pelvic lymphadenectomy plus n-butyl cyanoacrylate (treatment group: 44 patients) and pelvic lymphadenectomy without n-butyl cyanoacrylate (control group: 44 patients). Primary endpoint was incidence of pelvic lymphocele in the two groups 30 days after surgery, and evaluated with pelvic ultrasound and RMI examination. Secondary endpoints evaluated drainage volume of lymphorrhea 36, 48, 72 and 96 h after surgery. RESULTS: 15% in the treatment group and 36.6% in the control group had lymphocele 1month after the procedure (p<0.03; RR 0.4 [95% CI 0.152-0.999]). Concerning the secondary outcome in group A the amount of lymphorrhea presented a constant significant decrease during evaluation; on the contrary, in group B, after an initial decrease at 48 h, the amount of lymphorrhea remained unchanged; at all considered times the amount of lymphorrhea resulted significantly greater in controls. CONCLUSION: Intraoperative application of n-butyl cyanoacrylate seems to reduce lymph production after pelvic lymphadenectomy, providing a useful additional treatment option for reducing drainage volume and preventing lymphocele development after pelvic lymphadenectomy.

GOALS: To evaluate differences and changes in quality of life (QoL), lifestyle behavior and employment experience of young in comparison to midlife adults in response to early stage gynecologic cancer diagnoses. METHODS: 263 patients, divided into two age groups (Group A: ≤ 45 and Group B: >45 years), were interviewed on their QoL, lifestyle behavior (dietary habits, tobacco and alcohol use, physical activity) and employment experience (employment status and working time) at diagnosis and within 4 years from the treatment. The QoL was evaluated by European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire C30 (QLQ-C30) and its specific modules for each cancer type (in particular endometrium, cervix, ovarian and breast). RESULTS: Global health status was significantly different between the two groups. In the younger age group a more relevant cancer interference on family life and social activities and a greater impact on perception of health status have been observed. Young women were more affected by fatigue, constipation, gastrointestinal symptoms, lymphedema, poor body image and impaired sexuality. Cancer diagnosis had a major negative impact on employment of younger patients. Conversely, younger patients had overall better health behavior. They reported a higher daily intake of fruits and vegetables, along with lower alcohol consumption, furthermore they were a little more physically active than midlife adults. CONCLUSIONS: To enhance quality of life and to promote healthy lifestyle behavior of female cancer patients, particularly in younger age, it is essential to assure multidisciplinary approaches with specific medical intervention and psychosocial supports. Indeed, midlife adults seem to have a more rapid adaptive tendency to return towards levels of well-being, following cancer diagnosis and treatment, than younger patients.

This paper describes an experience with the Alphascope, a fibreoptic hysteroscopy system (Gynecare, Ethicon Women's Health and Urology). This prospective observational study was carried out at a tertiary hospital in Naples, Italy. The study population comprised patients undergoing outpatient hysteroscopy with the semi-rigid Versascope Hysteroscopy System using the Alphascope. 7-Fr gauge mechanical instruments and 5-Fr bipolar electrodes (Versapoint, Gynecare, Ethicon Inc., Somerville, NJ) were used for the operative procedures. Outpatient hysteroscopy was successful in 97% of cases. These were diagnostic in 41%, while operative hysteroscopy was performed in 59% of cases. The endoscopic view was subjectively defined by the operator as good/excellent in 95% of procedures. A total of 98% of patients expressed moderate/high degree of satisfaction and only 2% were dissatisfied. The system is successful in the outpatient setting in 95% of attempts.

Background: Medical 3D imaging is a promising emerging technology that allows recreating the details of human anatomy. The use of this innovative technology has resulted in improved surgical efficiency and better clinical outcomes. However, its incorporation in gynaecologic surgery has not been widely adopted. Objectives: To demonstrate the use of Hyper Accuracy 3D reconstruction in a patient with infertility who underwent multiple myomectomy. Materials and Methods: A stepwise approach describing the incorporation of Hyper Accuracy 3D imaging technology into the preoperative surgical planning and intraoperative guidance of a patient with multiple myomas undergoing multiple myomectomy. Main Outcome Measures: Preoperative evaluation of a patient with multiple myoma and infertility who presented to our department seeking surgical management. Hyper Accuracy 3D image was obtained, and a 3D digital image reconstruction of the uterus delineating the exact number, volume, and location of the fibroids was created. The 3D digital image was available during the surgical procedure which helped to plan the surgical steps allowing a systematic surgical approach resulting in an effective surgery with minimal blood loss. Results: The benefits of intraoperative guidance using Hyper Accuracy 3D in a patient with multiple myomas and infertility are demonstrated. Conclusions: The adoption of this promising imaging technology into gynaecologic surgery is feasible and should be further investigated. Additional studies evaluating the clinical impact of using Hyper Accuracy 3D imaging in the preoperative planning of patients with gynaecologic surgical pathology are needed.
RESUMO
BACKGROUND: Primary endometrial squamous cell carcinoma (PSECC) is a rare neoplasm. Squamous epithelium derived from endometrioid cancer or from cervical squamous cell carcinoma. The prevalence is about 0.1%. The genesis, histogenesis and biological behavior are unknown. CASE PRESENTATION: A 48-year old woman in postmenopause, referring pelvic pain and vaginal bleeding. Transvaginal ultrasound showed a bulky uterus with the endometrium containing an hyperecogenic area. Endometrial biopsy found an epidermoid carcinoma. MRI showed a 4 x 2 x 1.2 cm mass occupying the uterine cavity. The patient underwent radical treatment. Pathological examination showed features of PSECC. The mutation of p53 tumor suppressor protein was disclosed in 15% of neoplastic cells. PCR revealed the absence of HPV DNA. CONCLUSIONS: The findings of our case move us to underline that the pathogenesis of this tumor is still unclear. Moreover, preoperative diagnosis and staging of PESCC is extremely difficult. Most patients do not show characteristic symptoms and predisposing factors, making it almost impossible to diagnose the precise localization of tumor origin.

The ATP-dependent molecular chaperone Hsp70 is over-expressed in cancer cells where it plays pivotal roles in stabilization of onco-proteins, promoting cell proliferation and protecting cells from apoptosis and necrosis. Moreover, a relationship between the ability of cancer cells to migrate and the abundance of membrane-associated Hsp70 was shown. However, although Hsp70 is a promising target for cancer therapy, there is a still unsatisfied requirement of inhibitors possibly blocking its cancer-associated activities. Moving from the evidence that the plant diterpene oridonin efficiently targets Hsp70 1A in cancer cells, we set up a small kaurane diterpenoids collection and subjected it to a Surface Plasmon Resonance-screening, to identify new putative inhibitors of this chaperone. The results obtained suggested epoxysiderol as an effective Hsp70 1A interactor; therefore, using a combination of bioanalytical, biochemical and bioinformatics approaches, this compound was shown to bind the nucleotide-binding-domain of the chaperone, thus affecting its ATPase activity. The interaction between epoxysiderol and Hsp70 1A was also demonstrated to actually occur inside cancer cells, significantly reduced the translocation of the chaperone to the cell membrane, thus suggesting a possible role of epoxysiderol as an anti-metastasis agent.

Adenosarcoma is an extremely rare malignancy of the female genital tract composed of stromal sarcoma with a benign epithelial component. Current treatment recommendations include total hysterectomy with bilateral salpingo-oophorectomy, precluding future fertility. Although most frequently diagnosed in postmenopausal women, it is occasionally present in younger women of reproductive age with desire for future fertility. In 2015, we reported the case of a 23-year-old patient diagnosed with uterine adenosarcoma, who having strong desire of future fertility, opted for fertility sparing surgery. At a follow-up five years later, we can now report her case of spontaneous pregnancy and livebirth. A review of the literature concerning fertility outcomes in patients with uterine adenosarcoma undergoing fertility sparing therapeutic options is presented.
RESUMO
OBJECTIVE: To evaluate the effects on bleeding pattern of two different doses of natural progesterone (NP) administered per os or per vagina in association with transdermal estradiol in a continuous, sequential estrogen-progestin therapy. METHODS: A prospective, randomized trial was conducted on 100 patients randomized into four groups. Each group received transdermal 17beta-estradiol treatment at the dose of 50 microg/day. Groups A and B received NP per os at the dose of 100 mg/day and 200 mg/day, respectively. Groups C and D received NP per vagina at the dose of 100 mg/day and 200 mg/day, respectively. RESULTS: After 12 cycles of treatment, no significant differences were observed in endometrial thickness between groups, suggesting that all treatments are effective in balancing the effects of estradiol on endometrium. Regarding bleeding control, patients in Groups C and D showed a higher number of episodes of regular bleeding than patients in Groups A and B and fewer episodes of spotting. The better control of bleeding was associated with a higher treatment compliance in patients who received vaginal NP, with a larger percentage of women completing the study. CONCLUSION: Transdermal estrogen replacement therapy combined with 100 mg of micronized NP administered per vagina from the 14th day to the 25th day of each 28-day cycle leads to good cycle control and provides excellent patient satisfaction without serious side-effects. This therapy could be a treatment of first choice in early postmenopausal patients.

BACKGROUND: Mucinous ovarian cancer raises problems of differential diagnoses because it is often difficult to distinguish the primary from the metastatic form. Most metastatic ovarian tumors originate from the gastrointestinal tract, mainly colorectal, gastric, pancreatic; the gallbladder is a very rare source of ovarian metastases. CASE: We report a case of ovarian metastases from a gallbladder cancer, incidentally diagnosed more than 2.5 years earlier during a laparoscopic intervention for biliary lithiasis. CONCLUSION: The interest of this case lies in the long progression-free survival, the venous thromboembolism syndrome that preceded by a few months the diagnosis of the ovarian mass and the discrepancy between the radiologic and the laparoscopic stage assessment.

Trabectedin is a marine-derivate antitumor drug with a relevant cytotoxic activity and good safety profile. It has been investigated for the treatment of solid diseases, including ovarian cancer (OC), breast cancer, and soft-tissue sarcoma. In 2009, results from the pivotal trial OVA-301 led the European Medicines Agency (EMA) to the approval of trabectedin in combination with PEGylated liposomal doxorubicin for the treatment of platinum-sensitive recurrent OC; further studies revealed an additional benefit also in the subgroup of patients with partially platinum-sensitive disease and in those with a BRCA-mutated status. Additionally, trabectedin demonstrated to prolong the time interval to the subsequent chemotherapy line. Recently, the improved understanding of the antitumor action exerted by trabectedin paved the way to new investigational trials exploring its combination with targeted therapies.

BACKGROUND: The therapeutic value of lymphadenectomy in early stage endometrial cancer (EC) is still debated. Sentinel-lymph-node identified with indocyanine green (ICG) can replace lymphadenectomy in the staging of endometrial cancer minimizing the potential morbidity of a complete lymphadenectomy. The aim of this study was to analyze our initial experience using indocyanine green for sentinel-lymph-node mapping in a minimally robotic-assisted laparoscopic approach with Da Vinci XI near-infrared (NIR) fluorescence imaging system. METHODS: A total of 23 patients who underwent robot-assisted laparoscopic surgery with the Da Vinci Xi Surgical System (Intuitive Surgical, Sunnyvale, CA, USA) with NIR imaging and ICG fluorescence detection for early stage EC were retrospectively analyzed. RESULTS: Sentinel-lymph-node mapping was achieved in 18 patients for a detection rate of 78.26%, bilateral pelvic detection was possible in 14 patients (60.9%) and no sentinel-lymph-node mapping was noted in 4 patients (17.4%). We compared 11 patients (Group 1) at intermediate and high- risk of recurrence who underwent sentinel-lymph- node mapping and pelvic lymphadenectomy and 12 patients (Group 2) at low risk of recurrence who underwent only sentinel-lymph-node mapping. A statistically significant difference was found for the average operation time and for the hospital stays. CONCLUSIONS: The high detection rate, absence of intraoperative or postoperative complications, the short time required for mapping and removal of the sentinel-lymph-nodes and the short duration of the hospital stay, support performing sentinel-lymph-node in all women with early endometrial cancer.
RESUMO
PURPOSE OF INVESTIGATION: aberrant gene function and transcriptional silencing by CpG island hypermethylation have become a critical component in the initiation and progression of endometrial cancer. The aim of this study was to investigate the methylation status of genes associated with aberrant DNA hypermethylation in benign, premalignant and malignant endometrial lesions. METHODS: using nested methylation-specific PCR, we assessed the methylation of the promoter regions of two genes, hMLH1 and CDKN2A/p16, in tissue samples from endometrial polyps (EP), atypical hyperplasia (AH) and endometrial cancer (EC). RESULTS: the promoter region of at least one of the two genes was aberrantly methylated in EP (hMLH1 42%, CDKN2A/p16 16%), AH (hMLH1 16%, CDKN2A/p16 50%), EC (hMLH1 50%, CDKN2A/p16 75%). Interestingly, hypermethylation of both genes was found with significant increased frequence in AH and EC, but not in benign lesions. CONCLUSIONS: our preliminary findings seem to suggest that the association of the two genes hMLH1 and CDKN2A/p16 may allow a differential diagnosis between benign and premalignant/malignant endometrial lesions; this further supports the hypothesis that methylation of such DNA mismatch repair and tumour-suppressor genes may be associated with endometrial carcinogenesis thus representing a valuable target for selective pharmacologic therapy.

BACKGROUND: Primary retroperitoneal mucinous cystadenoma is a rare tumor only 48 cases have been reported in international literature. Patients affected by primary retroperitoneal mucinous cystadenoma/cystadenocarcinoma ranged in age from 17 to 86 years (median, 42.3 years) and the size of the cystis ranged from 5 to 35 cm (median, 16.1 cm). There is no unanimous opinion on the genesis of these tumors and, due to their extreme rarity, its histogenesis, biological behavior and the optimal management strategy remain at a speculative level. CASE REPORT: We report the case of a huge borderline primary retroperitoneal mucinous cystadenoma (24 x 25 cm) in a 35-year-old woman and the strategies adopted for the diagnosis and surgical management. CONCLUSION: Primary mucinous cystic tumor of the retroperitoneum was correctly diagnosed only at the time of surgery. As well as in the majority of cases reported in the literature, preoperative investigations were not able to give information about the tumor site. In spite of the short follow-up (two years), the patient's favorable course supports the hypothesis that primary retroperitoneal mucinous cystadenoma may be treated in the same manner as a primary ovarian tumor of the same grade and comparable stage.

Mesonephric adenocarcinoma deriving from remnants of vaginal mesonephric ducts is one of the rarest tumors of the female genital tract with only three cases reported till date in international literature. Differential diagnosis from other aggressive tumors is complex and controversies exist in the literature regarding the biological behavior, prognosis, and optimal management strategies of these tumors. A 58-year-old woman presented with a large mass extending from the right adnexal region to the perineum and labia majora. CA125 was increased. A radical excision of the lesion with pelvic and para-aortic lymphadenectomy was performed. A well-capsulated mesonephric adenocarcinoma in a background of vaginal mesonephric remnants was diagnosed. Tumor cells showed immunoreactivity for pancytokeratin, cytokeratin (CK), CD 10, epithelial membrane antigen, vimentin, and calretinin; indeed they were negative for carcinoembryonic antigen, CK 20, estrogen receptor, and progesterone receptor. No evidence of lymph node involvement or metastatic disease was observed. The patient did not receive any adjuvant therapy and is alive and clinically free of disease at 1-year follow-up. In spite of the aggressive biological behavior attributed in literature to mesonephric carcinomas, which is probably due to the complex differential diagnosis with other müllerian tumors, the favorable course of our patient further supports the hypothesis that malignant mesonephric carcinomas may not behave aggressively and that radical surgery alone may be curative.

OBJECTIVE: Cesarean scar pregnancy (CSP) is a rare condition that occurs when the pregnancy implants in a cesarean scar. An early diagnosis and a proper management are fundamental to prevent maternal complications. We review and discuss the different treatment employed in our unit to reduce morbidity, preserve fertility, and predict possible complications. METHODS: The reported treatment has been expectant management, operative hysteroscopy approach, and intramuscular injection of 50 mg methotrexate (MTX), followed by cervical dilation and manual vacuum aspiration (D&S) with a Karman cannula under ultrasound guidance, uterine artery embolization (UAE), and manual vacuum aspiration under ultrasound guidance and uterine artery embolization before surgical laparotomic resection. RESULTS: Complications were more frequent in women with a history of three or more cesarean section deliveries and with a myometrial thickness thinner than 2 mm. MTX and D&S treatment appear to be most effective and safe at the early age of pregnancy, while UAE and D&S are related to the highest risk of complication in any age of pregnancy. CONCLUSION: An appropriate preoperative diagnostic evaluation, the identification of cases at higher risk, and those eligible for a conservative treatment are fundamental to reduce complications.

BACKGROUND: The uterine cervix represents an exceptional localization of signet-ring cell adenocarcinoma (SRCA). Most commonly, endocervical tumors with such morphology are metastatic from the breast or gastrointestinal tract while primary pure or almost pure tumors are extremely rare. No previous case of primary pure endocervical SRCA with follow-up longer than three years has been found in the literature. CASE REPORT: The present report describes such a case of a 46-year-old woman without evidence of recurrence eight years after the diagnosis. The patient was referred to the Gynecology Department for persistent abnormal vaginal bleeding of three months duration. Specular examination and colposcopy revealed a cervical polypoid lesion occupying the posterior lip of the cervix and protruding from the external uterine orifice. A biopsy of the lesion was interpreted by the pathologist as SRCA. An extensive search for an extrapelvic primary cancer was undertaken but revealed no evidence of malignancy. The patient underwent radical hysterectomy with bilateral salpingo-oophorectomy and pelvic and paraaortic lymph node sampling for FIGO Stage 1B1 cervical cancer without any adjuvant chemo- or radiotherapy. The histological diagnosis showed neoplastic signet-ring cells confined in the head of the cervical polyps with minimal stromal infiltration. After surgery the patient underwent close followup including periodic cervicovaginal smears, bimanual vaginal examination, complete laboratory tests, ultrasound and abdominopelvic computed tomography. CONCLUSIONS: The prognostic relevance of primitive pure SRCA in the uterine cervix is unclear because of the relatively small number of cases. However the two early deaths out of six reported cases and the absence of follow-up longer than three years for the other affected patients, seem to suggest an aggressive behavior. The present case represents an exceptional long-term survival, probably related to an early diagnosis and a prominent polypoid growth of the neoplasia outside the uterus.
