Abstract
PURPOSE To determine whether abagovomab maintenance therapy prolongs recurrence-free (RFS) and overall survival (OS) in patients with ovarian cancer in first clinical remission. PATIENTS AND METHODS Patients with International Federation of Gynecology and Obstetrics stage III to IV ovarian cancer in complete clinical remission after primary surgery and platinum- and taxane-based chemotherapy were randomly assigned at a ratio of 2:1 in a phase III, double-blind, placebo-controlled, multicenter study. Abagovomab 2 mg or placebo was administered as 1-mL suspension once every 2 weeks for 6 weeks (induction phase) and then once every 4 weeks (maintenance phase) until recurrence or up to 21 months after random assignment of the last patient. The primary end point was RFS; secondary end points were OS and immunologic response. RESULTS Characteristics of the 888 patients included: mean age, 56.3 years; Eastern Cooperative Oncology Group performance status, ≤ 1 in > 99% of patients; serous papillary subtype, 81.5%; stage III, 85.9%; and cancer antigen 125 ≤ 35 U/mL after third cycle, 80.9%. Mean exposure to study treatment (± standard deviation) was 449.7 ± 333.08 days. Hazard ratio (HR) of RFS for the treatment group using tumor size categorization (≤ 1 cm, > 1 cm) was 1.099 (95% CI, 0.919 to 1.315; P = .301). HR of OS using tumor size categorization (≤ 1 cm, > 1 cm) was 1.150 (95% CI, 0.872 to 1.518; P = .322). The most frequently reported type of adverse event was an injection site reaction in 445 patients (50.2%), followed by injection site erythema and fatigue in 227 (25.6%) and 212 patients (23.9%), respectively. By the final visit, median anti-anti-idiotypic antibody level was 493,000.0 ng/mL, indicating a robust response. CONCLUSION Abagovomab administered as repeated monthly injections is safe and induces a measurable immune response. Administration as maintenance therapy for patients with ovarian cancer in first remission does not prolong RFS or OS.

Abstract
Dose-dense (DD) regimens of combination chemotherapy may produce superior clinical outcomes, but the basis for these effects are not completely clear. In this study, we assessed whether a DD combinatorial regimen of low-dose cisplatin and paclitaxel produces superior immune-mediated efficacy when compared with a maximum tolerated dose (MTD) regimen in treating platinum-resistant ovarian cancer as modeled in mice. Immune responses generated by the DD regimen were identified with regard to the immune cell subset responsible for the antitumor effects observed. The DD regimen was less toxic to the immune system, reduced immunosuppression by the tumor microenvironment, and triggered recruitment of macrophages and tumor-specific CD8(+) T-cell responses to tumors [as determined by interleukin (IL)-2 and IFN-γ secretion]. In this model, we found that the DD regimen exerted greater therapeutic effects than the MTD regimen, justifying its further clinical investigation. Fourteen patients with platinum-resistant relapse of ovarian cancer received DD chemotherapy consisting of weekly carboplatin (AUC2) and paclitaxel (60-80 mg/m(2)) as the third- or fourth-line treatment. Serum was collected over the course of treatment, and serial IFN-γ and IL-2 levels were used to determine CD8(+) T-cell activation. Of the four patients with disease control, three had serum levels of IL-2 and IFN-γ associated with cytotoxic CD8(+) T-cell activity. The therapeutic effect of the DD chemotherapy relied on the preservation of the immune system and the treatment-mediated promotion of tumor-specific immunity, especially the antitumor CD8(+) T-cell response. Because the DD regimen controlled drug-resistant disease through a novel immune mechanism, it may offer a fine strategy for salvage treatment.

Abstract
Ovarian cancer remains the leading cause of death due to gynecologic malignancies. Most patients present with advanced disease at the time of diagnosis. Although many have a good initial response to surgical debulking and platinum-based chemotherapy, relapse is common, with the eventual development of chemotherapy resistance. Innovative treatments are needed in the remission setting to prolong the disease-free interval or prevent recurrence. Abagovomab is a murine monoclonal anti-idiotypic antibody (molecular weight: 165-175 kDa) that functionally imitates the tumor-associated antigen, CA-125. It has been shown to be well tolerated and to induce a sustained immune response in initial Phase I and II clinical trials. An ongoing, double-blind, placebo-controlled, multicenter, Phase III trial (MIMOSA) completed its double-blind period in December 2010 and will compare abagovomab maintenance therapy to placebo, which will definitively determine the efficacy of this immunotherapeutic approach in patients with ovarian cancer.

Abstract
BACKGROUND Many patients treated with radiotherapy to the pelvic region report a change in bowel habits. Loose stools, urgency and fecal incontinence may have a significant impact on daily life and social functioning. MATERIAL AND METHODS We attempted to follow up 789 women, treated with pelvic radiotherapy for a gynecological cancer during 1991 to 2003 at two departments of gynecological oncology in Sweden. A control group of 478 women from the Swedish Population Registry was also included. As a preparatory study, we made in-depth interviews with 26 women previously treated for gynecological cancer. Based on their narratives, we constructed a study-specific questionnaire including 351 questions and validated it face-to-face. The questionnaire covered questions of physical symptoms originating in the pelvis, demographics, psychological and quality of life factors. In relation to bowel symptoms, 60 questions were asked. RESULTS Six-hundred and sixteen (78%) gynecological cancer survivors and 344 (72%) control women participated. Two-hundred and twenty-six (37%) cancer survivors reported loose stools at least once a week. Eighty-three percent of the survivors with loose stools every day reported defecation urgency with fecal leakage, compared to 20% of cancer survivors without loose stools. Cancer survivors with loose stools at least once a week were 7.7 times more likely to suffer from defecation urgency with fecal leakage (95% CI 4.4-13.3) compared to those who had loose stools once a month or less. In order to avoid loose stools affected survivors with loose stools often skipped meals (13%), made an active choice of food (47%) and preferentially used prescribed medication (36%). DISCUSSION There is a relation between loose stools and defecation urgency with fecal leakage among long-term gynecological cancer survivors treated with pelvic radiotherapy. Targeting loose stools can possibly help survivors to decrease frequency of fecal leakage.

Abstract
BACKGROUND Ovarian cancer (OC) is associated with a >75% risk of recurrence after completion of primary therapy. Several clinical trials have explored the role of continued therapy after complete response to primary adjuvant therapy to reduce the risk of recurrence; however, these trials have largely been underpowered, leading to inconclusive results. METHODS A systematic search strategy was initiated to identify all clinical trials involving consolidation or maintenance therapy regimens for OC in first complete remission. A meta-analysis was conducted to evaluate toxicity and progression-free (PFS) and overall survival (OS). RESULTS There were 37 publications meeting all eligibility criteria, representing 20 consolidation and 9 maintenance therapy trials. Consolidation and maintenance therapies were associated with improved PFS (hazard ratio [HR], 0.79 [P = .003] and HR, 0.82 [P = .02], respectively) and OS (HR, 0.68 [P = .0008] and HR, 0.68 [P = .007], respectively). This relationship remained statistically significant when the analysis was limited to randomized trials and across other sensitivity analyses. CONCLUSIONS Although individual studies have not yet convincingly shown a survival advantage with maintenance chemotherapy in OC, this meta-analysis demonstrates that continued chemotherapy after completion of primary therapy for OC improves PFS and OS. Benefits are greatest in patients with advanced stage OC who reach complete clinical or pathologic response after primary therapy.

Abstract
INTRODUCTION Despite enormous efforts to improve therapeutic strategies for patients with advanced ovarian carcinoma, outcome remains poor even with the advent cisplatinum-based chemotherapy regimen or taxanes with over 70% of patients developing local failure. Several trials were able to establish the potential benefit of adjuvant whole abdominal RT (WAI) though at the cost of sometimes marked side-effects. New technologies like IMRT have the potential of sparing normal tissues thus also potentially limiting treatment-related toxicity, hence a phase I trial was initiated to evaluate potential clinical benefit of WAI with IMRT. We intended to demonstrate that whole-abdominal IMRT is feasible and can be used in a routine clinical setting. METHODS A water-equivalent phantom containing OARs was created simulating organ shape of the upper abdomen to investigate the necessary number of beams for the upper abdominal target irrespective of the number of segments and hence treatment times. We prescribed a total dose of 30 Gy in 1.5 Gy fractions to the median of the target. IMRT treatment plans for three patients with advanced ovarian cancer were created using 2 isocentres and between 12 and 14 beams while restricting the number of segments so as to restrict treatment times to less than 45 min. Dose to OARs such as kidneys and liver was strictly limited even below established maxima. RESULTS In the phantom plans, no clear indication as to the optimum number of beams could be shown though there seems to be a slight trend toward a higher number of beams yielding better results. Examples demonstrating clinically inacceptable dose distributions for plans using only 9 beams. Acceptable treatment plans for real patients could be achieved using 12-14 beams and 2 isocentres. Treatment plans consisted of 264-286 segments resulting in an overall treatment time of approximately 37-45 min. Mean doses to the kidneys could be limited to 29.3% [23.1-33.2%] (right), and 26.8% [21-30.4%] (left). 50% of the liver received less than 72.4% [61-83%]. CONCLUSION IMRT for whole abdominal irradiation in patients with advanced ovarian carcinoma is applicable and feasible though treatment planning is complex and time-consuming. There is a significant reduction of dose to critical organs by using IMRT while maintaining target volume coverage.

Abstract
Even after countered with and responding to maximal surgical and chemotherapy efforts, advanced ovarian cancer usually ultimately recurs. One strategy employed to forestall recurrence is maintenance chemotherapy, an extension of treatment following a complete response to conventional measures. Many agents have been studied and many more are currently under investigation in maintenance regimens. While phase III data suggest that taxane maintenance prolongs progression-free survival, no overall survival benefit has been established. This article reviews the current status of maintenance therapy for advanced ovarian cancer, including phase III evidence and new and upcoming trials.

Abstract
PURPOSE.: To describe the characteristics of a series of study populations of ovarian cancer patients with identical eligibility criteria in second or subsequent clinical remission (cCR) and to propose endpoint benchmarks for future consolidation studies. PATIENTS AND METHODS.: The patient populations consisted of those (1) untreated (U; observed until progression; n=35, (2) receiving imatinib (G; n=32), (3) receiving goserelin and bicalutamide (A; n=32), and (4) receiving vaccine (V; n=68; total=167). The endpoint of the combined analysis was progression-free survival in second remission (PFS 2). Patient characteristics were compared by chi-square test, and factors predicting PFS 2 evaluated in multivariate Cox model. RESULTS.: Groups were comparable for age, stage, grade, and debulking. Multivariate model to predict PFS 2 duration included histology, stage, optimal debulking, PFS 1 duration, and the type of intervention. As a benchmark for future studies, the median PFS 2 of the combined population of G, A, and U (removing V which had the most impact in prolonging PFS 2, n=68) was 11.3 months (95% CI: 10.4-12.5 months). The percent of patients with PFS 2>PFS 1 was 14/90 (16%). At 12 months, 43% remain progression-free. CONCLUSION.: Preliminary benchmarks for efficacy endpoints are suggested for future consolidation trials of patients in cCR. However, the suggested strategies will require validation in randomized trials and larger data sets.

Abstract
Objectives:To evaluate current strategies under investigation for use as consolidation or maintenance treatment in patients with ovarian cancer.Patients with epithelial ovarian cancer often enter a complete remission after primary treatment. Many relapse, unfortunately, but some can return to remission after additional treatment. Outcomes can be improved by applying effective consolidation or maintenance approaches to patients in a complete primary or subsequent remission.Methods:A selective review of the literature is undertaken to consider strategies that are being or will likely be evaluated in randomized trials while we assess whether consolidation or maintenance will have a place in the treatment of patients with ovarian cancer.Results:The application of extended standard cytotoxic agents has been generally disappointing, and no strategy applied in the first remission setting has prolonged overall survival.Conclusions:As treatment options move beyond classic chemotherapy to novel hormones, immune interventions, and biologic agents, the consolidation strategy is regaining interest. This is particularly attractive in that many of these agents have stable disease as best outcome, and this is most appropriate to evaluate in patients with minimal volume disease. A consideration of toxicity is paramount, and any strategy to be considered in an otherwise asymptomatic patient in remission must be well tolerated. In addition, patients in second or third complete remission are also being considered as an appropriate group in which to evaluate new agents. Numerous other phase 2 trials with novel agents not considered here are underway, and it is to be hoped that some will emerge as contenders for randomized trials. Participation in these trials remains a priority for patients who otherwise must pursue a difficult watch-and-wait strategy.

Abstract
Background: The examination of the use of whole abdomen irradiation open field technique in optimally debulked patients with no residual disease with epithelial ovarian cancer (OC). Methods: Between 1993 and 2007, 20 patients with optimally cytoreduced epithelial OC were treated with WAI. The stage distribution was stage I in 15 patients, stage II in 1, and stage III in 4. The grade distribution was grade 1 in 10 patients, grade 2 in 4, and grade 3 in 6. WAI consisted of 30 Gy, delivered in daily fractions, mainly of 1.5 Gy (95%), 5 days/weekly, in 14 patients. After abdominal irradiation, in 75% of the patients a pelvic boost, and in 7 a boost to other risk sites was given to reach 45 - 50 Gy. Nine patients received platinum based chemotherapy (CT). Median follow-up was 7.96 years. Results: The overall survival (OS) rate was 82% and 70% at 5 and 10 years. A tendency to better survival was found in patients with age ? 40 than in those with > 40 years (100%:100% vs. 68%:51%; p=0.03). Patients with grade 1-2 tumors had significantly better 5- and 10-year survival rate than those with grade 3 tumors (100%:100% vs. 40%:20%; p<0.00). The 5- and 10-year OS for the patients 'with' and 'without' a pelvic boost turned to be in favor of the patients 'with' the boost (91%:91% vs. 60%:40%; p=0.02). In 15 patients (75%) RT was transiently interrupted because of acute gastrointestinal and hematological toxicity. Neither grade 4 acute complications nor was mortality observed. Late gastrointestinal effect developed in 1 patient, presented with grade 4 complications. The development of second primary malignancy was not observed during the follow-up period. Conclusion: WAI achieves a quite favorable 5- and 10-year survival rate with an acceptable risk of acute and late side effects in properly selected patients with epithelial OC.

Abstract
Consolidation therapy is used in order to maximize the benefit of first-line therapy and to improve the progression-free and overall survival of patients. In women with advanced epithelial ovarian cancer, tested maintenance and consolidation strategies following first-line chemotherapy include high-dose chemotherapy, radiation therapy, intraperitoneal radionuclides including those linked to an antibody, and biological and immunologic agents. This review focuses on the current understanding of the benefit of radiation therapy and biological agents used as consolidation in women with advanced ovarian cancer. Whole abdominal radiation has given promising results only in the subgroup of patients with pathologic complete response. However, this treatment modality is associated with considerable intestinal toxicity. Single treatment with intraperitoneal radionuclides, either alone (32P) or in combination with an antibody (90Y-muHMFG1) has not improved survival. Biological agents used for consolidation include, eg, alpha- and gamma-interferon, tanomastat, a matrix metalloprotease inhibitor and oregovomab, a murine antibody that targets CA125. Randomized trials with these agents have not demonstrated any significant improvement in the overall survival of ovarian cancer patients. Currently, two ongoing studies (GOG 218, ICON7) are examining the potential of bevacizumab in the maintenance therapy of advanced epithelial ovarian cancer. Evaluation of new agents is indicated in order to achieve long-term disease-free survival in these patients. Toxicity and ease of administration must be reflected against the benefits of therapy.

Abstract
TheInternational Symposium on Advanced Ovarian Cancer: Optimal Therapywas founded by Dr. Andrés Poveda and Prof. Jan B. Vermorken, and each edition has been directed by them. The 6th edition was held on March 2, 2007. This symposium is organized every other year by GEICO (Grupo Español de Investigación de Cáncer de Ovario/Spanish Ovarian Cancer Research Group), under the auspices of the Spanish Society of Medical Oncology (SEOM), the Gynecologic Cancer Intergroup (GCIG), and the European Society of Medical Oncology (ESMO) Educational Committee for its Medical Oncology Recertification Approval (ESMO/MORA) Program. One hundred and fifty people attended the symposium's 1st edition, held in 1996. Since then, the interest in this meeting has increased. Last year, almost three hundred people coming not only from Spain but also from Europe, North and Latin America, Asia, and Australia were present in the symposium. This is a great challenge for us. Some important international cooperative groups from Europe, America, and Australia collaborate with this symposium, such as GOG, NCIC, EORTC, AGO, Scottish Group, ICON, GINECO, NSGO, ANZGOG, and others.

Abstract
Epithelial ovarian cancer originates in the layer of cells that covers the surface of the ovaries. The disease spreads readily throughout the peritoneal cavity and to the lymphatics, often before causing symptoms. Of the cancers unique to women, ovarian cancer has the highest mortality rate. Most women are diagnosed as having advanced stage disease, and efforts to develop new screening approaches for ovarian cancer are a high priority. Optimal treatment of ovarian cancer begins with optimal cytoreductive surgery followed by combination chemotherapy. Ovarian cancer, even in advanced stages, is sensitive to a variety of chemotherapeutics. Although improved chemotherapy has increased 5-year survival rates, overall survival gains have been limited because of our inability to eradicate all disease. Technologic advances that allow us to examine the molecular machinery that drives ovarian cancer cells have helped to identify numerous therapeutic targets within these cells. In this review, we provide an overview of ovarian cancer with particular emphasis on recent advances in operative management and systemic therapies.

Abstract
OBJECTIVES Despite several studies reporting various degrees of success, the role of maintenance chemotherapy in ovarian cancer remains controversial. This article reviews the available data and the controversy surrounding maintenance therapy. In addition, the role of novel taxanes, which may offer an improved therapeutic index and reduced toxicity relative to conventional therapies in this setting, is discussed. METHODS The available randomized clinical data on extended or maintenance therapy in ovarian cancer are reviewed. RESULTS Available data indicate that patients with ovarian cancer undergoing taxane maintenance chemotherapy exhibit a reduced recurrence rate and a longer progression-free survival. CONCLUSIONS While an additional randomized trial is needed to confirm these benefits and establish maintenance therapy as the standard of care, the authors conclude that maintenance therapy is a valuable option that should be discussed with patients until further data are available. The Gynecologic Oncology Group 212 trial is a randomized clinical trial that is designed to answer whether taxane maintenance therapy offers a survival advantage as well as to determine the impact of such a therapeutic regimen on a patient's quality of life. This trial is also designed to address some of the questions regarding the role of a novel taxane in maintenance therapy in ovarian cancer.

Abstract
Uterine papillary serous carcinoma (UPSC) is more aggressive than endometrioid endometrial cancer, as it often presents with advanced disease and follows a pattern of spread that resembles the serous carcinoma of the ovary. There exists little data on evaluating the combination of carboplatin and paclitaxel in UPSC. Institutional Review Board permission was obtained for a retrospective review. Tumor registry search was used to identify all patients with UPSC from 1990 to 2003. Charts were retrospectively evaluated from patients who had received at least three cycles of carboplatin and paclitaxel as first-line chemotherapy. Only patients with histologically confirmed UPSC who were treated first line with carboplatin/paclitaxel chemotherapy were included. Nineteen patients with UPSC were identified, who were treated with carboplatin and paclitaxel in the first-line adjuvant setting after initial surgical cytoreduction. All patients received at least three cycles, with 12 of the 19 patients receiving six cycles. Five patients were treated with consolidation radiotherapy following first-line chemotherapy. Mean age was 69 years (range 55-88). The majority of patients had stage III disease (n= 11). Mean follow-up for the group was 29.5 months (7-76 months). A median progression-free interval of 12 months was seen across the entire cohort. Fourteen patients achieved a complete response following chemotherapy. The results of Gynecologic Oncology Group protocol 122 suggest that patients with advanced endometrial cancer have an improved progression-free survival when treated primarily with chemotherapy rather than radiation therapy. The results of our study show a high response rate to paclitaxel/carboplatin outpatient chemotherapy in a group of patients historically believed to have chemoresistant disease. Further prospective study of this regimen is planned.

Abstract
We evaluated the clinical role of the combination of positron emission tomography (PET) with F-18 fluorodeoxyglucose (FDG) and tumor marker CA125, in the detection of recurrence after initial therapy for epithelial ovarian cancer. The indication is the cases that cannot be confirmed the recurrence by conventional imaging modalities. Ninety patients underwent PET and computed tomography, including the measurement of specific tumor markers. FDG-PET confirmed recurrence in 46 patients (51%), and the recurrent site was confirmed by PET alone in 17 (37%). PET had high sensitivity for detecting both intraperitoneal and retroperitoneal metastases (93.9 and 92.9%, respectively). PET imaging was able to detect normal-sized metastases in the lymph nodes in 14 (50%) of the 28 patients with retroperitoneal metastasis. PET could show 87.5% positive rate of recurrent patients with asymptomatic rise of CA125 who had no sign of recurrence by conventional imaging methods. Of the 46 recurrent patients, 41 (89%) had specific elevated titers of CA125 at the first treatment. PET imaging was able to detect recurrence at relatively low titers (a median 68 U/mL) of CA125. In 8 (19.5%) of these 41 patients, recurrence with normal CA125 levels could be confirmed only by PET. The sensitivity of the combination of PET and CA125 was 97.8% with only one false-negative case. The combination of FDG-PET and CA125 titer is useful for the accurate detection of recurrence.

Abstract
Ovarian cancer (OC) is one of the leading causes of cancer-related death in women. In the last decades, a lot of energy and resources have been put into a number of clinical trials, with some success. Nevertheless, the prognosis of patients diagnosed with advanced disease remains extremely poor. As research moved forward, some crucial questions with regard to the optimal upfront management of patients with advanced OC (AOC) have remained unanswered. In this article, we review the rationale behind these controversial issues, and provide the levels of evidence supporting the current recommendations for AOC management.
