Efficacy and Safety of Apatinib Combined with Etoposide in Patients with Recurrent Platinum-resistant Epithelial Ovarian Cancer: A Retrospective Study.

Advanced epithelial ovarian cancer (EOC) eventually develops into a recurrent platinum-resistant disease. The response to standard treatment and prognosis in patients with EOC is generally unsatisfactory. This study aimed to assess the efficacy and safety of apatinib combined with etoposide in patients with recurrent platinum-resistant EOC.

Label-free detection of miRNA cancer markers based on terminal deoxynucleotidyl transferase-induced copper nanoclusters.

The variations in microRNA (miRNA) expression levels can be useful biomarkers for the diagnosis of different cancers. In this work, a label-free and sensitive fluorescent method for detection of miRNA-21 is described based on duplex-specific nuclease (DSN) assist target recycling and terminal deoxynucleotidyl transferase (TdT) induced copper nanoclusters (CuNCs). In the absence of target, the 3'-phosphorylated probe DNA cannot be hydrolyzed by DSN and extended by TdT, and failed to synthesizing fluorescent CuNCs.

Isolation, Culture and Identification of Choriocarcinoma Stem-Like Cells from the Human Choriocarcinoma Cell-Line JEG-3.

Background/aims: Cancer stem cells (CSCs) exhibit enhanced proliferative capacity and resistance to chemotherapy; however, choriocarcinoma CSCs have not yet been reported. In this study the human choriocarcinoma cell line JEG-3 was cultured in serum free media, and the characteristics of suspension and parental adherent JEG-3 cells were compared.

Methods: Cell proliferation, colony-formation, soft agar clonogenicity, and transwell invasion assays were performed in vitro, and tumor xenografts in BALB/c nude mice were used to evaluate stem cell properties.

[Comparative study of different chemotherapy approaches for advanced epithelial ovarian cancer].

Objective: To probe into the advantages and disadvantages of intravenous chemotherapy and intraperitoneal chemotherapy for advanced epithelial ovarian cancer.

Methods: All of the 226 patients with advanced epithelial ovarian cancer were treated by maximum cytoreductive surgery or non-effective cytoreductive surgery and received 6 - 8 courses of postoperative regular chemotherapy (chemotherapy regimens, TP: taxol and cis-platinum or carboplatinum; PC: cis-platinum and cyclophosphamide; PAC: cis-platinum and adriamycin and cyclophosphamide) during Jan 1998 - Jan 2006. We systematically compared the characteristics of patients in intraperitoneal chemotherapy (IPC) group and intravenous chemotherapy (IVC) group.
