Epithelial ovarian cancer is the leading cause of death from gynecologic cancer and the fifth most common cause of cancer mortality in women in the United States. Fewer than 40% of women with ovarian cancer are cured, and 70% of patients present with advanced disease; because of the location of the ovaries, ovarian cancer has been difficult to diagnose at earlier stages. Epidemiologic studies have identified risk factors, including family history. The NCCN guidelines discuss epithelial ovarian cancer as well as less common ovarian histopathologies, including germ cell neoplasms, carcinosarcomas (malignant mixed Müllerian tumors of the ovary), and ovarian stromal tumors. For 2008, updates include the addition of platinum-based combination therapy as a possible treatment modality for recurrence and a listing of preferred agents for acceptable recurrence modalities. New information was also added to the section on clinical presentation. For the most recent version of the guidelines, please visit NCCN.org

Epithelial ovarian cancer is the leading cause of death from gynecologic cancer in the United States and is the country’s fifth most common cause of cancer mortality in women. A major challenge in treating ovarian cancer is that most patients have advanced disease at initial diagnosis. These NCCN Guidelines discuss cancers originating in the ovary, fallopian tube, or peritoneum, as these are all managed in a similar manner. Most of the recommendations are based on data from patients with the most common subtypes─high-grade serous and grade 2/3 endometrioid. The NCCN Guidelines also include recommendations specifically for patients with less common ovarian cancers, which in the guidelines include the following: carcinosarcoma, clear cell carcinoma, mucinous carcinoma, low-grade serous, grade 1 endometrioid, borderline epithelial, malignant sex cord-stromal, and malignant germ cell tumors. This manuscript focuses on certain aspects of primary treatment, including primary surgery, adjuvant therapy, and maintenance therapy options (including PARP inhibitors) after completion of first-line chemotherapy.

e13125 Background: Epithelial ovarian cancer (EOC) is the second most common gynecologic cancer in the United States, and carries the highest mortality in this category in the West. The progression free survival and overall survival depend greatly on tumor sensitivity to a platinum chemotherapy. Once platinum resistance is encountered, response rates of only 6–30% are achieved. A relatively new modality in EOC that would allow targeted treatments is a PARP inhibitor, a drug that inhibits the enzyme poly (ADP-ribose) polymerase (PARP), which is showing promise for the treatment of EOC with mutations in the BRCA1 or BRCA2 tumor suppressors. Triapine, a novel small-molecule drug developed in our laboratory, potently inhibits the activity of ribonucleotide reductase involved in the key step of DNA synthesis and replication. Methods: 1. Cell sensitivity to varying ratios of treating drug combinations (Triapine with cisplatin; PARP inhibitor, olaparib) was carried out by clonogenic survival assays using multiple EOC cell lines (A2780, Caov-3, EFO, IGROV-1, BG-1, PEO1, SKOV3). 2. AKT level was measured in the cell lines before and after treatment. 3. BRCA1 wild-type and BRCA1-knockdown EOC cells were treated with cisplatin or PARP alone and in combination with Triapine. Drug-induced DNA damage was assessed by the levels of g-H2AX, the marker of double stranded breaks (DSBs), and of Rad51 foci, a marker of HR repair of DSBs. Results: Treatment with Triapine leads to synergistic sensitization of BRCA1 wild-type EOC cells to platinum drugs and to olaparib. Both platinum drugs and olaparib induce DNA damage that is repaired by HR. This suggests that Triapine inhibits HR and sensitizes EOC cells to these drugs. Triapine attenuates olaparib-induced Rad51 foci in BRCA1-wild type cells, which resembles the impairment of such foci formation in BRCA1-knockdown cells. Triapine causes down-regulation of AKT activity in EOC cells. Conclusions: Triapine produces synthetic lethality by inhibiting both DNA repair and pro-survival pathways. Combination of Triapine and platinum drugs/PARP inhibitors represents a rational and innovative therapy that targets EOC with a high level of AKT activity.

Abstract Background: Epithelial Ovarian Cancer (EOC) is the second most common gynecologic malignancy in the United States, but the leading cause of gynecologic cancer death. Despite many achieving remission with first-line therapy, up to 80% of patients will recur and require additional treatment. Antibiotic therapy is frequently used during cancer treatments for both prophylaxis and treatment of infections, although this profoundly impacts the gut microbiome. Multiple studies suggest that an unperturbed gut microbiome may provide a protective microenvironment, and disruption may be permissive to tumor growth and chemotherapy resistance, including platinum agents. Experimental Design: We assessed whether antibiotic therapy would impact growth of EOC and sensitivity to cisplatin in murine models. Immune competent or compromised mice were given control or antibiotic (ABX) containing water (metronidazole, ampicillin, vancomycin, and neomycin) for two weeks before being intraperitoneally injected with murine ID8 or ID8-VEGF EOC cells. Tumors were monitored and cisplatin therapy was administered weekly until endpoint. Stool was collected throughout the study to assess for microbial population effects over time. Cecal microbiota transplants (CMTs) of contents derived from ABX or control treated donor mice were performed on ABX treated recipient mice. Results: Both immune competent and immune compromised ID8 and ID8 VEGF tumor-bearing mice demonstrated a decreased response to cisplatin therapy in ABX treated groups with an increase in overall tumor burden. RNAseq analysis showed enrichment of multiple cell proliferation and stem cell pathways, and stem cell genes SOX2, WNT and PAX2. The self-renewal of cancer cells derived from tumors of ABX treated mice was increased compared to tumors from control mice, indicative of a microbiota derived tumor suppressor. Conclusion: Collectively, these studies indicate an intact microbiome provides a tumor suppressor and maintains chemosensitivity that is disrupted by ABX treatment.

Improvement In Survival

This chapter focuses on the three types of gynecologic cancer—epithelial cancer of the ovary, cancer of the uterine cervix, and cancer of the endometrium (uterine cancer)—and reviews their epidemiology, diagnosis, differential diagnosis, surgical features, and staging, as well as their risk factors and clinical features. Also discussed are methods of treatment and the management of relapse. Epithelial ovarian cancer occurs at a mean age of 60 years in the United States and is the most lethal of gynecologic tract tumors. However, a recent trial has demonstrated a survival advantage through the use of intraperitoneal chemotherapy for appropriate patients with optimally debulked ovarian cancer. Invasive cervical cancer is uncommon in developed countries, partly because of the effectiveness of Pap smear screening. Nevertheless, cancer of the uterine cervix is the third most common gynecologic cancer diagnosis and cause of death among gynecologic cancers in the United States. However, for women with early-stage cervical cancer, data from several randomized trials indicate an improvement in response rate and survival through the use of combination platinum-based regimens for platinum-sensitive relapse. Also noted is an improvement in survival using combined-modality chemoradiation in appropriate patients with locally advanced cervical cancer. Endometrial cancer is the most frequent tumor of the gynecologic tract; it is estimated that it occurred in over 46,000 women and caused more than 8,000 deaths in the United States in 2011. Recent data indicate improvement in survival using adjuvant platinum-based chemotherapy in appropriate patients with high-risk endometrial cancer. Tables in this chapter review the common histologic types of epithelial ovarian cancer, selected signs and symptoms of ovarian cancer, the International Federation of Gynecology and Obstetrics (FIGO) staging system for epithelial ovarian cancer, differential diagnosis of a complex cyst detected by transvaginal sonography, selected adverse prognostic factors in epithelial ovarian cancer, common chemotherapy agents used in the treatment of epithelial ovarian cancer, the FIGO surgical staging of endometrial cancer, and postoperative management considerations for patients with uterine cancer. Figures illustrate the four histologic subtypes of epithelial ovarian cancer, the intraoperative appearance of stage III epithelial ovarian cancer, and FIGO staging of cervical cancer. This review contains 6 highly rendered figures, 8 tables, and 150 references.

Epithelial ovarian cancer is the leading cause of death from gynecologic cancer in the United States, with less than half of patients living >5 years from diagnosis. A major challenge in treating ovarian cancer is that most patients have advanced disease at initial diagnosis. The best outcomes are observed in patients whose primary treatment includes complete resection of all visible disease plus combination platinum-based chemotherapy. Research efforts are focused on primary neoadjuvant treatments that may improve resectability, as well as systemic therapies providing improved long-term survival. These NCCN Guidelines Insights focus on recent updates to neoadjuvant chemotherapy recommendations, including the addition of hyperthermic intraperitoneal chemotherapy, and the role of PARP inhibitors and bevacizumab as maintenance therapy options in select patients who have completed primary chemotherapy.

Epithelial ovarian cancer (EOC) is the most lethal gynecologic cancer (1). We performed discovery of genes associated with epithelial ovarian cancer and of the high-grade serous ovarian cancer (HGSC) subtype, using published and public microarray data (2, 3) to compare global gene expression profiles of normal ovary or fallopian tube with that of primary tumors from women diagnosed with epithelial ovarian cancer or HGSC. We identified the gene encoding SLIT and NTRK-like family member 3, SLITRK3, as among the genes whose expression was most different in epithelial ovarian cancer as compared to the normal fallopian tube. SLITRK3 expression was significantly lower in high-grade serous ovarian tumors relative to normal fallopian tube. SLITRK3 expression correlated with progression-free survival in patients with ovarian cancer. These data indicate that expression of SLITRK3 is perturbed in epithelial ovarian cancers broadly and in ovarian cancers of the HGSC subtype. SLITRK3 may be relevant to pathways underlying ovarian cancer initiation (transformation) or progression.
