Advances in paclitaxel combinations for treating cervical cancer

Introduction: Cervical cancer is the fourth common cancer in women worldwide. While, in the past, locally advanced stage disease was treated by pelvic radiotherapy, nowadays the National Cancer Institute strongly recommends chemoradiation protocols. Weekly cisplatin was previously the standard of care in this setting; however, the low response rate and the short median progression-free survival (PFS) of patients have led researchers to investigate combinatory regimens. Area covered: This article is based on literature searches up until April 2019, with current trial registers also analyzed. All data available on this topic has been summarized in this narrative review. Expert opinion: In recent years, it has been demonstrated that cisplatin-based doublets, and in particular, cisplatin plus paclitaxel, are superior to cisplatin as a monotherapy in terms of response rate and progression-free survival of patients with advanced cervical cancer. This double regime combined with bevacizumab is also considered the first-line option for metastatic or recurrent disease. Dose-dense paclitaxel in neo-adjuvant chemotherapy combinations is a promising option in patients with locally advanced cervical cancer. Exploration of novel biological therapies and in vitro combinations based on the use of paclitaxel is warranted

Microbiome and PCOS: State-of-art and future aspects

Polycystic ovary syndrome (PCOS) is a complex and heterogeneous endocrine disease. The hypothesis that alterations in the microbiome are involved in the genesis of PCOS has been postulated. Aim of this review is to summarize the available literature data about the relationship between microbiome and PCOS. A search on PubMed and Medline databases was performed from inception to November 20Most of evidence has focused on the connection of intestinal bacteria with sex hormones and insulin-resistance: while in the first case, a relationship with hyperandrogenism has been described, although it is still unclear, in the second one, chronic low-grade inflammation by activating the immune system, with increased production of proinflammatory cytokines which interfere with insulin receptor function, causing IR (Insulin Resistance)/hyperinsulinemia has been described, as well as the role of gastrointestinal hormones like Ghrelin and peptide YY (PYY), bile acids, interleukin-22 and Bacteroides vulgatus have been highlighted. The lower genital tract mi-crobiome would be affected by changes in PCOS patients too. The therapeutic opportunities include probiotic, prebiotics and synbiotics, as well as fecal microbiota transplantation and the use of IL-22, to date only in animal models, as a possible future drug. Current evidence has shown the involvement of the gut microbiome in PCOS, seen how humanized mice receiving a fecal transplant from women with PCOS develop ovarian dysfunction, immune changes and insulin resistance and how it is capable of disrupting the secondary bile acid biosynthesis. A future therapeutic approach for PCOS may involve the human administration of IL-22 and bile acid glycodeoxycholic acid

Is there a relationship between Vitamin D and endometriosis? an overview of the literature

Background: Vitamin D is involved in the physiological functions of several tissues, however, its deficiency may contribute to the development of various disorders. Recent research has been focusing on the role of Vitamin D in the pathogenesis of endometriosis based on the evidence of the presence of Vitamin D receptor and the enzymes required for Vitamin D synthesis in the ectopic endometrium. Endometriosis, defined as the presence of endometrial glands and stroma in ectopic locations, is considered an estrogen-dependent disease and Vitamin D seems to have a role in modulation of the inflammatory state and proliferation of endometriotic cells. Objective: This study aimed to review the available literature regarding the relationship between Vitamin D and endometriosis as well as the effects of Vitamin D supplementation. Methods: A search on PubMed database has been performed. Results: The relationship between endometriosis and Vitamin D has been analyzed through the evaluation of Vitamin D serum level, the polymorphism of Vitamin D receptor and the role of Vitamin D-binding protein in patient with endometriosis. The possible role of Vitamin D in the endometriosis therapy has also been investigated, in particular, the effect of Vitamin D on pain relief, on endometriotic lesion in vitro and in rat models and in addition to a future target immunotherapy. Conclusion: Although promising, the data analyzed are not sufficient to evidence a cause-effect relationship between VD status and endometriosis, therefore further studies are needed in order to better clarify the association between Vitamin D and endometriosis, especially in the context of the possibility of new treatment options

Dioxin and endometriosis: a new possible relation based on epigenetic theory

Endometriosis is a chronic disease characterized by the growth of endometrial-like glands and stroma outside the uterine cavity. Nowadays, the exact etiology of endometriosis is unclear and the interaction between a variety of environmental physical and chemical compounds may potentially promote the disease in women with an individual susceptibility. The first demonstration of a relation between an environmental factor and endometriosis was obtained with the chronic dietary exposure of a primate colony to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). Besides the well-known dioxin’s pathway of action, several papers are focusing on the role of epigenetic mechanisms, a way through which the genome responds to the environment and can lead to permanent changes in gene expression until affecting the phenotypes or cause disease. In this review, we focus on the possible role of dioxin epigenetics modification in endometriosis

Improved anchoring of SSS with vacuum barrier to avoid displacement

As presented in the previous speech, the incident in sector 3-4 of the LHC caused a high pressure build-up inside the cryostat insulation vacuum resulting in high longitudinal forces acting on the insulation vacuum barriers. This resulted in braking floor and floor fixations of the SSS with vacuum barrier. The strategy of improving anchoring of SSS with vacuum barrier to avoid displacement is presented and discussed

Hysteroscopic approach to uterine cervical canal stenosis

Cervical stenosis is defined as an adhesion process of variable degree, producing narrowing, distortion, or complete obliteration of the cervix. Several techniques have been defined to access to the uterine cavity and nowadays hysteroscopy seems to be the best option. In this manuscript, we review all the hysteroscopic modalities to overcome a cervical stenosis and access to the uterine cavity

Role of biomarkers for early detection of ovarian cancer recurrence

Ovarian cancer is frequently diagnosed at an advanced stage and a fraction of these patients fail to respond to primary therapy and relapses in 70% of cases. On account of the high recurrence probability and the poor outcomes after recurrence, there is an urgent need to predict progression as early as possible and thus found the strategies to detect and prevent a recurrence. Considering that biomarkers have contributed to the management of ovarian cancer by distinguishing benign and malignant pelvic masses and monitoring response to treatment, in this review, we aim to discuss the latest evidence reported in the literature about the use of biomarkers to detect OC recurrence. In detail, we summarized all the evidence of the most quoted biomarkers like HE4, osteopontin, mesothelin (MSLN), Folate receptor α (FOLR1), paraneoplastic antigens, miRNA, cancer stem cells (CSCs) and a combination of them to evaluate their role as prognostic biomarkers for ovarian cancer recurrence

Fertility sparing management of uterine adenosarcoma: Case report and literature review

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

Hysteroscopic vaginoscopy. An additional diagnostic tool for recto-vaginal deep infiltrating endometriosis

Endometriosis is the presence of endometrial tissue outside the uterine cavity. Rectovaginal infiltration is present in 5% to 25% of the patients diagnosed with endometriosis. Accurate diagnosis is imperative for adequate counseling. Hysteroscopic vaginoscopy allows the inspection of the posterior vaginal fornix, not only providing better visualization of the area due to image magnification, but also allowing to obtain biopsy providing pathologic confirmation. We report the case of a 49-year-old nulliparous patient with long history of severe dysmenorrhea, deep dyspareunia and debilitating chronic pelvic pain not responding to medical treatment. On physical exam, recto-vaginal tender nodularity was palpated. Vaginal ultrasound and magnetic resonance imaging confirmed the presence of the nodular formation extending up to the rectum. In-office vaginoscopy revealed a perforated bulge on the uterine cervix, mimicking a double cervix. A biopsy of the nodule confirmed the presence of endometrial tissue, confirming the diagnosis of endometriosis. Patient underwent total hysterectomy with excision of deep infiltrating endometriosis which required segmental bowel resection with diverting loop colostomy. The final pathology confirmed the diagnosis of deep infiltrating endometriosis
