Ovarian cancer is the main cause of death from gynaecological malignancies. In spite of the efficacy of platinum-paclitaxel treatment in patients with primary epithelial ovarian carcinoma, platinum-based chemotherapy is not curative and resistance remains one of the most important causes of treatment failure. Although ABC transporters have been implicated in cellular resistance to multiple drugs, the clinical relevance of these efflux pumps is still poorly understood. Thus, we examined the prognostic role of transporters of the MRP family (i.e., ABCC1/MRP1, ABCC4/MRP4) to gain insights into their clinical impacts. A case material of 127 patients with ovarian carcinoma at different stages and histotypes was used. The expression of MRP1 and MRP4 was examined by immunohistochemistry using tissue microarrays in tumor specimens collected at the time of initial surgery expression. We found an association between MRP1 expression and grading, and we observed that MRP4 displayed an unfavourable impact on disease relapse in multivariate analysis (HR = 2.05, 95% CI: 1.01–4.11;P=0.045). These results suggest that in epithelial ovarian cancer, MRP1 may be a marker for aggressiveness because its expression was associated with tumor grade and support that MRP4 may play an unfavourable role in disease outcome.

The aim of this study was to compare the outcome of patients with advanced ovarian carcinoma treated with neoadjuvant chemotherapy (NACT) with those treated conventionally with primary debulking surgery. From 1994 to 2003, all consecutive cases of advanced-stage epithelial ovarian carcinoma treated with NACT at the University of Bari were identified. A well-balanced group of women who underwent primary debulking surgery followed by platinum-based chemotherapy was selected as controls. Kaplan–Meier and Cox proportional hazards analyses were used to determine the predictors for survival. Thirty women with advanced-stage epithelial ovarian carcinoma were treated with NACT and compared to 30 patients who underwent primary debulking surgery. Patients in the NACT were significantly older and had a poorer performance status compared to the controls. However, no statistical difference was observed in overall disease-specific survival (P = 0.66) and disease-free survival (P = 0.25) between the two groups. Although patients in the NACT group are significantly older and have a poorer performance status, this treatment modality does not compromise survival. Prospective randomized trials comparing NACT to conventional treatment to determine the quality of life and cost/benefit outcomes are now appropriate for women presenting advanced epithelial ovarian cancer.

Epithelial ovarian carcinoma is the most predominant type of ovarian carcinoma, the deadliest gynecologic malignancy. It is typically diagnosed late when the cancer has already metastasized. Transcoelomic metastasis is the most predominant mechanism of dissemination from epithelial ovarian carcinoma, although both hematogenously and lymphogenously spread metastases also occur. In this review, we describe molecular mechanisms known to regulate organ-specific metastasis from epithelial ovarian carcinoma. We begin by discussing the sites colonized by metastatic ovarian carcinoma and rank them in the order of prevalence. Next, we review the mechanisms regulating the transcoelomic metastasis. Within this chapter, we specifically focus on the mechanisms that were demonstrated to regulate peritoneal adhesion—one of the first steps in the transcoelomic metastatic cascade. Furthermore, we describe mechanisms of the transcoelomic metastasis known to regulate colonization of specific sites within the peritoneal cavity, including the omentum. Mechanisms underlying hematogenous and lymphogenous metastatic spread are less comprehensively studied in ovarian cancer, and we summarize mechanisms that were identified to date. Lastly, we discuss the outcomes of the clinical trials that attempted to target some of the mechanisms described in this review.

<p>Ovarian carcinoma is one of the leading causes of morbidity and mortality associated with carcinomas affecting women. It comprises a heterogeneous group of neoplasms that represents the seventh most lethal malignancy in women worldwide, and is a major cause of death from gynecological carcinoma. Specific to different geographical locations all over the globe, there are variations in the magnitude and trends of ovarian carcinoma, and the scenario of the disease keeps changing. As such, it is necessary to update and review the existing study on ovarian carcinoma. Reviews on ovarian cancer from 2000 to 2015 were extracted from PubMed and Google Scholar, and a few selected landmark studies that incorporated old data were also included. The focus of the present study is to consolidate an updated global view on epithelial ovarian carcinoma, the most prevalent type of ovarian carcinoma. This article covers the epidemiology, types, diagnosis, prognosis, and treatment of epithelial ovarian carcinoma.</p>

American Cancer Society identifying ovarian carcinoma as the gynecologic malignancy with the highest case-to-fatality. Ovarian carcinoma metastasizes either by direct extension from the ovarian/fallopian tumor to neighboring organs (bladder/colon) or when cancer cells detach from the primary tumor. Exfoliated tumor cells are transported throughout the peritoneum by physiological peritoneal fluid and disseminate within the abdominal cavity. Extensive seeding of the peritoneal cavity by tumor cells is often associated with ascites, particularly in advanced, high-grade serous carcinomas. CD70 (encoded by the TNFSF7 gene) is a co-stimulatory factor present on B-cells, activated T-cells, and dendritic cells. CD70 is over expressed in tumor cells of various solid cancers including ovarian carcinoma, recently reported the role of CD70 expression as a predictive marker of resistance to chemotherapy in ovarian cancers. We evaluated the expression of CD70 level in the pathogenesis of metastasis ovarian cancer cell. Seventy five tissue samples from metastatic ovarian carcinoma were evaluated by quantitative real-time PCR for CD70 and statistical analyses were performed using the Mann-Whitney test. Further, humanized anti-CD70 antibodies were investigated in xenograft mice models of ovarian cancer. Increasing expression of CD70 level was associated with increased risks for disease progression (HR = 1.04; 95% CI, 1.03 to 1.14) and death (HR = 1.13; 95% CI, 1.09 to 1.2). expression of CD70 was associated with a worse PFS and OS compared with non- expression of CD70 carcinomas. Furthermore, humanized anti-CD70 antibodies have shown significant antitumor activity in preclinical xenograft models of ovarian cancer cell.
