INTRODUCTION The SCAN gynaecological cancers systemic therapy workgroup aimed to develop Singapore Cancer Network (SCAN) clinical practice guidelines for front-line systemic therapy of advanced epithelial ovarian cancer. MATERIALS AND METHODS The workgroup utilised a modified ADAPTE process to calibrate high quality international evidence-based clinical practice guidelines to our local settin...

This case report describes the clinical course of a heavily pretreated patient enrolled on the Phase II QUADRUPLE THREAT clinical trial (NCT02489903) with recurrent metastatic epithelial ovarian cancer that was previously treated with a platinum doublet and that benefited from another reintroduction of a platinum doublet after a brief priming period with RRx-001. Platinum-taxane combination is ...

Cancer stem cells (CSCs, also called cancer stem-like cells, CSLCs) can function as "seed cells" for tumor recurrence and metastasis. Here, we report that, in the presence of CD133+ ovarian CSLCs, CD133- non-CSLCs can undergo an epithelial-mesenchymal transition (EMT)-like process and display enhanced metastatic capacity in vitro and in vivo. Highly elevated expression of chemokine (C-C motif) ...

OBJECTIVE The aim of the present study is to investigate the differential expression of Beclin1, HMGB1, p62, survivin, ERCC1 and BRCA1 protein in epithelial ovarian cancer (EOC) and to evaluate the relationship between autophagy and platinum resistance of EOC patients during platinum-based chemotherapy with the protein expression. PATIENTS AND METHODS Expression of Beclin1, HMGB1, p62, surviv...

Metaphase comparative genomic hybridization was used to analyze the spectrum of genetic alterations in 141 epithelial ovarian cancers from BRCA1 and BRCA2 mutation carriers, individuals with familial non-BRCA1/2 epithelial ovarian cancer, and women with nonfamilial epithelial ovarian cancer. Multiple genetic alterations were identified in almost all tumors. The high frequency with which some al...

This study investigated the role of LOX in promoting invasion and metastasis of epithelial ovarian cancer in a hypoxic environment and its specific signal transduction pathway. Immunohistochemical detection of HIF-1α and LOX protein expression was performed on formalin-fixed paraffin sections of normal ovary, benign ovarian tumors, borderline and malignant epithelial ovarian tumor paraffin samp...

Epithelial ovarian carcinomas account for more than 90% of human ovarian cancers and have become the primary cause of death for gynecological malignancies. Unlimited cell proliferation and resistance to cell apoptosis contribute to the development of ovarian cancers. However, the underlying mechanisms involved in these processes in epithelial ovarian carcinomas are yet poorly understood. In the...
