Epithelial ovarian cancer (EOC) is the one of most common gynecological malignant tumor with highest mortality, meanwhile, series of lncRNAs have been validated to play vital role in EOC tumorigenesis. Colon cancer-associated transcript 2 (CCAT2) has been verified as oncogenic lncRNA in multiple tumors, however, the role of CCAT2 in EOC genesis is still unclear. The purpose of present study is to probe the function of CCAT2 on EOC. Preliminary experiments found that CCAT2 expression was significantly up-regulated in EOC tissue and cell lines compared to noncancerous tissue and cells...

Synchronous gynecological cancers are rarely described. Those cases account for approximately up to 6% of female genital tract malignancies. The presence of synchronous endometrial adenocarcinoma and gynecological tract neoplasia is rare - the most commonly described is synchronous adenocarcinoma and endometrial ovarian cancer (accounting for 15-20% of ovarian neoplasia and 5% of endometrial cancers). Concomitant uterine carcinosarcoma and ovarian cancer, or endometrial adenocarcinoma are extremely rare. Up till now, only 3 cases of synchronous adenocarcinoma and leiomyosarcoma were described...

BACKGROUND: Ovarian cancer is one of the most lethal gynecological malignancies, in which platinum resistance is a common cause of its relapse and death. Glycosylation has been reported to be involved in drug resistance, and glycomic analyses of ovarian cancer may improve our understanding of the mechanisms underlying cancer cell drug resistance and provide potential biomarkers and therapeutic targets. METHODS: The serous ovarian cancer cell line A2780 and its platinum-resistant counterpart A2780-cp were used in this study...

OBJECTIVE: To report on the incidence of nab-paclitaxel hypersensitivity reactions (HSRs) in patients with prior taxane HSR. METHODS: From 2005 to 2015, all patients who received nab-paclitaxel for a gynecologic malignancy were identified. Chart abstraction included pathology, prior therapy, indication for nab-paclitaxel, dosing, response, toxicities including any HSR, and reason for discontinuation of nab-paclitaxel therapy. RESULTS: We identified 37 patients with gynecologic malignancies with a history of paclitaxel HSR who received nab-paclitaxel...

Peritoneal surface malignancy (PSM) is a common manifestation of digestive and gynecologic malignancies alike. At present, patients with isolated PSM are treated with a combination therapy of cytoreductive surgery (CRS) and hyperthermic peroperative intraperitoneal chemotherapy (HIPEC). The combination of CRS and intraperitoneal (IP) chemotherapy should now be considered standard of care for PSM from appendiceal epithelial cancers, colorectal cancer and peritoneal mesothelioma. Although there is a near universal standardization regarding the CRS, we are still lacking a much-needed standardization amongst the various IP chemotherapy treatment modalities used today in clinical practice...

Carcinosarcomas (CS) in gynecology are very infrequent and represent only 2-5% of uterine cancers. Despite surgical cytoreduction and subsequent chemotherapy being the primary treatment for uterine CS, the overall five-year survival rate is 30 ± 9% and recurrence is extremely common (50-80%). Due to the poor prognosis of CS, new strategies have been developed in the last few decades, targeting known dysfunctional molecular pathways for immunotherapy. In this paper, we aimed to gather the available evidence on the latest therapies for the treatment of CS...

Endometrial carcinoma (EC) is one of the most common gynecologic malignancy, but molecular mechanisms of the development and progression of EC remain unclear. Here we showed that the expression of DICER1 was negatively associated with the level of histone methylation, histone acetylation and PRC2 components SUZ12 and EZH2 in EC cells. In addition, knockdown of DICER1 significantly downregulated miR-200b and let-7i, which may then regulate their targets SUZ12 and EZH2. Furthermore, knockdown of DICER1 remarkably suppressed the expression of epithelial cell marker E-cadherin, induced the expression of mesenchymal cell marker Vimentin, and promoted the invasion of EC cells...

Endometrial cancer (EC) is the estrogen-dependent gynecologic malignancy, however the molecular mechanism involved in the development and progression of EC remain unclear. The aim of this study was to investigate the role of RIZ1 in EC. Immunohistochemical analysis revealed that RIZ1was decreased in EC than in normal endometrium. Lower RIZ1 level was correlated with high-grade carcinoma (p = 0.048) and positive expression of ERα (p = 0.004). In EC cells, estrogen could down regulated the expression of RIZ1, however, ICI182,780 could up regulated the expression of RIZ1...

Anemia, which is highly prevalent in oncology patients, is one of the most established negative prognostic factors for several gynecologic malignancies. Multiple factors can cause or contribute to the development of anemia in patients with gynecologic cancers; these factors include blood loss (during surgery or directly from the tumor), renal impairment (caused by platinum-based chemotherapy), and marrow dysfunction (from metastases, chemotherapy, and/or radiation therapy). Several peri- and intra-operative strategies can be used to optimize patient management and minimize blood loss related to surgery...

Synchronous multiple malignant neoplasms of the female genital tract are rare, particularly in the uterus. We herein present the case of a patient with synchronous cervical squamous epithelial carcinoma and endometrial adenocarcinoma, and discuss the diagnosis, treatment and prognosis. The patient underwent a cervical biopsy and fractional curettage of the endometrium, followed by abdominal staging surgery, including radical hysterectomy, bilateral salpingo-oophorectomy, pelvic and para-aortic lymphadenectomy...

For many women with endometrial and cervical cancers, minimally invasive surgery represents an alternative standard of care to open abdominal procedures, with fewer complications, better postoperative quality of life, and overall lower cost. At the NCCN 22nd Annual Conference, Amanda N. Fader, MD, reviewed several minimally invasive strategies for treating gynecologic cancers, including conventional laparoscopy, robotic-assisted laparoscopy, sentinel lymph node technology, and single-port surgery; highlighted some of the contemporary literature on the role of these procedures; and explored some of the challenges and barriers to their successful performance...

PURPOSE: Endometrial cancer is the most common gynecological malignancy in developed countries. There are no uniform recommendations for endometrial cancer screening in the general population. Therefore, it is of paramount importance that the primary physician profoundly understands, and is familiar with the methods for prevention and early detection of endometrial cancer. The aim of this review is to provide the primary physician with a toolbox to reach these goals. METHODS: We performed a systemic review to summarize the current strategies to diagnose and prevent endometrial cancer...

Ovarian cancer is the most lethal gynecological malignancy worldwide. Thiophenes such as terthiophene have been shown to have anti-tumor effects on several cancer cell lines, including ovarian cancer cells. However, the underlying mechanisms behind the anti-proliferative effect of thiophenes are poorly understood. In this study, we investigated the molecular mechanisms underlying the anti-proliferative effect of α-terthienylmethanol, a terthiophene isolated from Eclipta prostrata (False Daisy), on human ovarian cancer cells...

Ovarian cancer is the most lethal gynecologic malignancy and the molecular pathogenesis of high-grade serous ovarian carcinoma has not been completely characterized. Numerous studies have shown that altered splicing patterns and splicing factors were found to contribute to tumor development and progression. In this study, we demonstrated that spliceosome-associated factor CTNNBL1 was significantly upregulated in high-grade serous ovarian carcinoma, the elevated level of CTNNBL1 indicates poor prognosis in patients with high-grade serous ovarian carcinoma...

BACKGROUND: Despite clear data demonstrating feasibility, safety, and cost-effectiveness of same-day discharge after minimally invasive hysterectomy, there is a paucity of data suggesting ways to increase same-day discharge rates. OBJECTIVE: To promote same-day discharge following minimally invasive hysterectomy using preoperative patient education videos, provider same-day discharge awareness initiatives, and standardization of postoperative management. To investigate reasons for overnight admission after surgery (non-same-day discharge)...
