Abstract
Primary debulking surgery (PDS) has remained the only treatment of ovarian cancer with survival advantage since its development in the 1970s. However, survival advantage is only observed in patients who are optimally resected. Neoadjuvant chemotherapy (NACT) has emerged as an alternative for patients in whom optimal resection is unlikely and/or patients with comorbidities at high risk for perioperative complications. The purpose of this review is to summarize the evidence to date for PDS and NACT in the treatment of stage III/IV ovarian carcinoma. We systematically searched the PubMed database for relevant articles. Prior to 2010, NACT was reserved for non-surgical candidates. After publication of EORTC 55971, the first randomized trial demonstrating non-inferiority of NACT followed by interval debulking surgery, NACT was considered in a wider breadth of patients. Since EORTC 55971, 3 randomized trials-CHORUS, JCOG0602, and SCORPION-have studied NACT versus PDS. While CHORUS supported EORTC 55971, JCOG0602 failed to demonstrate non-inferiority and SCORPION failed to demonstrate superiority of NACT. Despite conflicting data, a subset of patients would benefit from NACT while preserving survival including poor surgical candidates and inoperable disease. Further randomized trials are needed to assess the role of NACT.

Abstract
BACKGROUND Epithelial ovarian cancer presents at an advanced stage in the majority of women. These women require a combination of surgery and chemotherapy for optimal treatment. Conventional treatment has been to perform surgery first and then give chemotherapy. However, there may be advantages to using chemotherapy before surgery. OBJECTIVES To assess whether there is an advantage to treating women with advanced epithelial ovarian cancer with chemotherapy before debulking surgery (neoadjuvant chemotherapy (NACT)) compared with conventional treatment where chemotherapy follows debulking surgery (primary debulking surgery (PDS)). SEARCH METHODS We searched the following databases up to 9 October 2020: the Cochrane Central Register of Controlled Trials (CENTRAL), Embase via Ovid, MEDLINE (Silver Platter/Ovid), PDQ and MetaRegister. We also checked the reference lists of relevant papers that were identified to search for further studies. The main investigators of relevant trials were contacted for further information. SELECTION CRITERIA Randomised controlled trials (RCTs) of women with advanced epithelial ovarian cancer (Federation of International Gynaecologists and Obstetricians (FIGO) stage III/IV) who were randomly allocated to treatment groups that compared platinum-based chemotherapy before cytoreductive surgery with platinum-based chemotherapy following cytoreductive surgery. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data and assessed risk of bias in each included trial. We extracted data of overall (OS) and progression-free survival (PFS), adverse events, surgically-related mortality and morbidity and quality of life outcomes. We used GRADE methods to determine the certainty of evidence. MAIN RESULTS We identified 2227 titles and abstracts through our searches, of which five RCTs of varying quality and size met the inclusion criteria. These studies assessed a total of 1774 women with stage IIIc/IV ovarian cancer randomised to NACT followed by interval debulking surgery (IDS) or PDS followed by chemotherapy. We pooled results of the four studies where data were available and found little or no difference with regard to overall survival (OS) (Hazard Ratio (HR) 0.96, 95% CI 0.86 to 1.08; participants = 1692; studies = 4; high-certainty evidence) or progression-free survival in four trials where we were able to pool data (Hazard Ratio 0.98, 95% CI 0.88 to 1.08; participants = 1692; studies = 4; moderate-certainty evidence). Adverse events, surgical morbidity and quality of life (QoL) outcomes were variably and incompletely reported across studies. There are probably clinically meaningful differences in favour of NACT compared to PDS with regard to overall postoperative serious adverse effects (SAE grade 3+): 6% in NACT group, versus 29% in PDS group, (risk ratio (RR) 0.22, 95% CI 0.13 to 0.38; participants = 435; studies = 2; heterogeneity index (I2) = 0%; moderate-certainty evidence). NACT probably results in a large reduction in the need for stoma formation: 5.9% in NACT group, versus 20.4% in PDS group, (RR 0.29, 95% CI 0.12 to 0.74; participants = 632; studies = 2; I2 = 70%; moderate-certainty evidence), and probably reduces the risk of needing bowel resection at the time of surgery: 13.0% in NACT group versus 26.6% in PDS group (RR 0.49, 95% CI 0.30 to 0.79; participants = 1565; studies = 4; I2 = 79%; moderate-certainty evidence). NACT reduces postoperative mortality: 0.6% in NACT group, versus 3.6% in PDS group, (RR 0.16, 95% CI 0.06 to 0.46; participants = 1623; studies = 5; I2 = 0%; high-certainty evidence). QoL on the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) scale produced inconsistent and imprecise results in three studies (MD -0.29, 95% CI -2.77 to 2.20; participants = 524; studies = 3; I2 = 81%; very low-certainty evidence) but the evidence is very uncertain and should be interpreted with caution. AUTHORS' CONCLUSIONS The available high to moderate-certainty evidence suggests there is little or no difference in primary survival outcomes between PDS and NACT. NACT probably reduces the risk of serious adverse events, especially those around the time of surgery, and reduces the risk of postoperative mortality and the need for stoma formation. These data will inform women and clinicians (involving specialist gynaecological multidisciplinary teams) and allow treatment to be tailored to the person, taking into account surgical resectability, age, histology, stage and performance status. Data from an unpublished study and ongoing studies are awaited.

Abstract
In January 2019, a group of basic, translational, and clinical investigators and patient advocates assembled in Miami, Florida, to discuss the current state of the science of low-grade serous carcinoma of the ovary or peritoneum-a rare ovarian cancer subtype that may arise de novo or following a diagnosis of serous borderline tumor. The purpose of the conference was to review current knowledge, discuss ongoing research by established researchers, and frame critical questions or issues for future directions. Following presentations and discussions, the primary objective was to initiate future collaborations, uniform database platforms, laboratory studies, and clinical trials to better understand this disease and to advance clinical care outside the boundaries of single academic institutions. This review summarizes the state of the science in five principal categories: epidemiology and patient outcomes, pathology, translational research, patient care and clinical trials, and patients' perspective.

Abstract
INTRODUCTION Treatment in locally advanced ovarian cancer is optimal surgery followed by chemotherapy. Patients with significant tumor spread, OMS>2, age>75 years old are poor candidates for aggressive primary surgery. Interval surgery, after neo-adjuvant chemotherapy, aims to achieve more complete surgery, increase survival, and reduce surgical morbidity. The primary endpoint was progression-free survival. Secondary outcomes were overall survival and postoperative morbidity and mortality. METHOD This is a retrospective study conducted in 2 French referral centers between January 2000 and December 2015. Patients who could not benefit from a complete initial surgery were operated after 3 cures of chemotherapy at the François Baclesse center and after least 5 cures at the center René Gauducheau. RESULTS The population analyzed included 104 patients, 43 (41.0%) patients treated at the René Gauducheau center (group 1) and 61 (59.0%) patients treated at the François Baclesse center (group 2). Progression-free and overall survival were similar between the 2 groups, they were, respectively, 15.9 months and 34 months in group 1 vs. 15.4 months and 37.6 months in group 2 (P=0.72; P=0.65). Mean hospital stay and postoperative morbidity were similar in both groups. CONCLUSION For weak patients, to limit invasive surgery, doing more than 5 courses of chemotherapy may be a reasonable option.

Abstract
Objective It is known that optimal or complete cytoreduction is the most important factor in patients with advanced ovarian cancer. The aim of this study was to examine the results of patients who did not undergo optimal cytoreduction and to examine subgroup analysis based on neoadjuvant chemotherapy (NAC). Material and Methods Patients with advanced ovarian cancer and suboptimal surgery were retrospectively reviewed. Results A total of 99 patients with a median age of 59.0 years (range, 22-87 years) were studied. The median follow-up time was 39±32.7 months, 81 patients (81.8%) died and 18 patients (18.2%) were alive. The five-year survival rate was 27.6%. Of the patients, 37 (37.4%) were underwent surgery after NAC, 62 (62.3%) were primary. More patients with NAC died within 3 years compared with those without NAC (83.9% vs 56.0%) (p=0.015). Patients with NAC had less tumor spread (presence of visible tumor in the upper abdomen during surgery) (29.7% vs 72.6%; p<0.001) and had less overall survival times when compared with patients who underwent primary surgery [median 22.3±1.2; 95% CI: (19.9-24.7) vs (37.5±11.2); 95% CI: (15.4-59.5) months; log rank test p=0.055]. The relationship between overall survival and factors such as age, NAC, presence of metastasis in the upper abdomen, and tumor histology (serous vs. non-serous) were analyzed using univariate cox regression analysis. Of these factors, only NAC was close to significant, but it did not reach significance (p=0.055). Conclusion NAC reduces tumor burden before surgery in advanced ovarian cancer. The prognosis of patients who are not eligible for optimal surgery despite NAC is worse than in patients who do not receive NAC.

Eur J Obstet Gynecol Reprod Biol 2017; 219:100-105. [PMID: 29078115 DOI: 10.1016/j.ejogrb.2017.10.019] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2017] [Revised: 10/14/2017] [Accepted: 10/17/2017] [Indexed: 01/10/2023]
Abstract
OBJECTIVE The aim of this study was to compare surgical results and survival outcome of advanced ovarian cancer patients who were treated with primary versus interval debulking surgery. STUDY DESIGN In this retrospective study stage III and IV ovarian cancer patients who received debulking surgery from 2006 to 2015 were included. Surgical results were described as complete, optimal or suboptimal debulking and chi-square test was used to assess significant differences. Overall survival was measured using Kaplan-Meier curves, the log-rank test and uni- and multivariable Cox regression analyses. RESULTS Of 146 patients included in the study, 55 patients were treated with primary debulking surgery (PDS) followed by adjuvant chemotherapy and 91 patients received neoadjuvant chemotherapy (NAC) followed by interval debulking surgery (IDS). Complete or optimal debulking (0-10mm of residual disease) was achieved in 76.4% (n=42) of the PDS group and in 79.1% (n=72) of the IDS group. Overall median survival was 38 months for PDS and 31 months for IDS, which was not significantly different (p=0.181). In the IDS group, a significant difference was found in OS between complete and optimal resection (p=0.013). Besides that, no difference in survival outcome was found in the IDS group between patients with optimal or suboptimal debulking (median survival were 20 and 19 months respectively). CONCLUSION Complete debulking surgery is of utmost importance, both in case of PDS and IDS. Achieving optimal interval debulking of 1-10mm residual disease did not show any survival benefit over suboptimal interval debulking.

Abstract
OBJECTIVE To analyze efficacy of neoadjuvant chemotherapy for advanced ovarian cancer. MATERIALS AND METHODS A total of 107 patients with advanced ovarian cancer undergoing cytoreductive surgery were divided into a neoadjuvant chemotherapy group (n=61) and a primary debulking group (n=46) and retrospectively analyzed. Platinum-based adjuvant chemotherapy was applied to both groups after cytoreductive surgery ande overall and progression-free survival times were calculated. RESULTS No significant difference was observed in duration of hospitalization (20.8±6.1 vs. 20.2±5.4 days, p>0.05). The operation time of neoadjuvant chemotherapy group was shorter than the initial surgery group (3.1±0.7 vs. 3.4±0.8 h, p<0.05). There were no significant differences in median overall survival time between neoadjuvant chemotherapy group and surgery group (42 vs. 55 months, p>0.05). Similarly, there was no difference in median progression-free survival between neoadjuvant chemotherapy group and surgery group (16 vs. 17 months, p>0.05). The surgical residual tumor size demonstrated no significant difference between initial surgery and neoadjuvant chemotherapy groups (p>0.05). Multivariate analysis showed that more than 3 cycles of regimen with neoadjuvant chemotherapy was associated with more resistance to chemotherapy compared with patients without receiving neoadjuvant chemotherapy (OR: 5.962, 95%CI: 1.184-30.030, p<0.05). CONCLUSIONS Neoadjuvant chemotherapy can shorten the operation time. However, it does not improve survival rates of advanced ovarian cancer patients.

Abstract
BACKGROUND Interval debulking surgery (IDS), following induction or neoadjuvant chemotherapy, may have a role in treating advanced epithelial ovarian cancer (stage III to IV) where primary debulking surgery is not an option. OBJECTIVES To assess the effectiveness and complications of IDS for women with advanced stage epithelial ovarian cancer. SEARCH METHODS We searched the Cochrane Gynaecological Cancer Group's Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL) 2012, Issue 6, MEDLINE and EMBASE for the original review in to June 2012. We updated the searches in June 2009, 2012 and 2015 for the review updates. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing survival of women with advanced epithelial ovarian cancer, who had IDS performed between cycles of chemotherapy after primary surgery with survival of women who had conventional treatment (primary debulking surgery and adjuvant chemotherapy). DATA COLLECTION AND ANALYSIS Two review authors independently assessed trial quality and extracted data. Searches for additional information from study authors were attempted. We performed meta-analysis of overall and progression-free survival (PFS), using random-effects models. MAIN RESULTS Three RCTs randomising 853 women, of whom 781 were evaluated, met the inclusion criteria. Meta-analysis of three trials for overall survival (OS) found no statistically significant difference between IDS and chemotherapy alone (hazard ratio (HR) = 0.80, 95% confidence interval (CI) 0.61 to 1.06, I² = 58%). Subgroup analysis for OS in two trials, where the primary surgery was not performed by gynaecologic oncologists or was less extensive, showed a benefit of IDS (HR = 0.68, 95% CI 0.53 to 0.87, I² = 0%). Meta-analysis of two trials for PFS found no statistically significant difference between IDS and chemotherapy alone (HR = 0.88, 95% CI 0.57 to 1.33, I² = 83%). Rates of toxic reactions to chemotherapy were similar in both arms (risk ratio = 1.19, 95% CI 0.53 to 2.66, I² = 0%), but little information was available for other adverse events or quality or life (QoL). AUTHORS' CONCLUSIONS We found no conclusive evidence to determine whether IDS between cycles of chemotherapy would improve or decrease the survival rates of women with advanced ovarian cancer, compared with conventional treatment of primary surgery followed by adjuvant chemotherapy. IDS appeared to yield benefit only in women whose primary surgery was not performed by gynaecologic oncologists or was less extensive. Data on QoL and adverse events were inconclusive.

Abstract
In the following study, extremely low frequency electromagnetic fields (EL-EMF) radiation was used to restore sensitivity in the cisplatin-resistant A2780 ovarian cancer cells. For this purpose A2780 cells were treated with different doses of cisplatin and EL-EMF (50 Hz, 200 gauss, and 2 h) alone. Cytotoxicity was the measurement using MTT assay. After calculating IC50 for cisplatin (90 µg/ml) a lower concentration from IC50 (30 and 60 µg/ml) was used to be combined with EL-EMF. We compare the effects of each cisplatin, EL-EMF and combination groups using acridine orange-propidium iodide (AO/PI) and DAPI staining, caspase 3/9 activation assay and Annexin/PI assay. We also assessed changes in P53 and Matrix metalloproteinases 2 (MMPs) gene expression with semi-quantitative RT-PCR. Results indicated an EL-EMF-dependent proliferative decrease which was found <10 %, and occurred independently of cisplatin. The decreased proliferation rate for 30 and 60 µg/ml cisplatin was about 20 and 40 %, respectively, while for synergistic groups 30 and 60 µg/ml cisplatin with 2 h EL-EMF exposer, showed 47 and 71 % decrease in viability in rats. DAPI staining indicated that chromatin break down significantly increased in synergistic groups. Acridine orange staining also confirmed MTT assay results. Caspase activity significantly increased in the combined groups. Semi-quantitative RT-PCR showed that in synergistic groups of cisplatin and EL-EMF, expression of P53 was increased but the expression level of MPP-2 gene decreased. Results from this study showed that changes generated by the non-invasive EL-EMF can make resistant cells sensitive to cisplatin.

Abstract
OBJECTIVE Effective biomarkers for early detection of ovarian cancer are needed. Our study previously showed that basement membrane protein, nidogen-1 plasma level was significantly increased in ovarian cancer patients. This study aimed to examine the plasma levels of nidogen-1 in a large patient population to evaluate its effectiveness in ovarian serous carcinoma and expression in tumor tissues. METHODS The concentration of nidogen-1 in circulating plasma specimens of 265 ovarian serous cancer patients and 98 healthy individuals were assayed by enzyme linked immunosorbent assay. The medical records of 265 ovarian serous cancer cases were reviewed retrospectively. The expression status of nidogen-1 in tumor tissues of 44 ovarian serous carcinoma patients was examined by immunohistochemical analysis. For statistical analysis, we used the Mann-Whitney U test, Fisher's exact test and receiver operating characteristic. RESULTS Protein levels of nidogen-1 were considerably raised in the plasma from ovarian serous cancer patients compared with those in healthy controls (P < 0.001), especially elevated in patients with advanced stage and those received neoadjuvant chemotherapy followed by interval debulking surgery. However, it was irrelevant to the grade, chemotherapy sensitivity or residual tumor of the ovarian serous carcinoma cases investigated (P > 0.05). Receiver operating characteristic curve analysis for nidogen-1 showed that it could discriminate patients with ovarian serous carcinomas from healthy controls [areas under the curve (AUC): 0. 65, 95%CI, 0.59-0.71], but CA125 was superior (AUC: 0. 98, 95%CI, 0.96-0.99). The immunohistochemical staining result showed that nidogen-1 protein was localized both in the cancer cell cytoplasm and intercellular substance, mainly expressed in extracellular matrix of ovarian serous carcinoma tissues (the positive rate was 77.3%). CONCLUSIONS Our study suggests that plasma nidogen-1 may be used as a diagnostic biomarker for ovarian serous carcinoma and can reflect the tumor burden.

Abstract
PURPOSE Ovarian cancer is the sixth common cancer in women in developed countries. In severe cases, the optimal debulking is necessary. In order to increase optimal debulking and reduce preoperative complications, neoadjuvant chemotherapy followed by debulking surgery, and then chemotherapy again is introduced as substitute for primary surgery. In this study, we aim to evaluate perioperative outcome after neoadjuvant chemotherapy with carboplatin/paclyaxol in comparison with primary cytoreduction in patients with advanced ovarian cancer. METHODS In this prospective study, 60 patients with advanced ovarian cancer due to the disease severity were assigned into neoadjuvant chemotherapy (n = 30) or control (n = 30) groups. In neoadjuvant chemotherapy group, patients received three cycles of carboplatin (5-6 area under the curve) and paclitaxel (175 mg/m(2)) preoperatively followed by interval surgery. The control group received primary surgery plus adjuvant chemotherapy. Preoperative outcome was compared between groups. RESULTS Neoadjuvant group had significantly lower mean levels of CA 125 (p = 0.01) and less severe bleeding (p = 0.03) than control group. There was no significant difference between surgery time, preoperative complications, residual mass less than 1 cm, and hospital stay between groups. There was no mortality during the study. CONCLUSION Neoadjuvant chemotherapy caused less severe bleeding, but has no effect in decreasing complications after surgery; however, neoadjuvant chemotherapy followed by interval debulking surgery was not superior to primary debulking surgery followed by chemotherapy as a treatment option for patients with advanced ovarian carcinoma in this study.

Abstract
OBJECTIVES To compare the survival and perioperative morbidity between primary debulking surgery (PDS) and neoadjuvant chemotherapy followed by interval debulking surgery (NAC/IDS) in treating patients with advanced epithelial ovarian cancer (EOC). METHODS We retrospectively reviewed 67 patients with stage IIIC or IV EOC treated at Peking University Cancer Hospital from January 2006 to June 2009. Wherein, 37 and 30 patients underwent PDS and NAC/IDS, respectively. RESULTS No difference in overall survival (OS) or progression-free survival (PFS) was observed between NAC/IDS group and PDS group (OS: 41.2 vs. 39.1 months, P=0.23; PFS: 27.1 vs. 24.3 months, P=0.37). The optimal debulking rate was 60% in the NAC/IDS group, which was significantly higher than that in the PDS group (32.4%) (P=0.024). The NAC/IDS group had significantly less intraoperative estimated blood loss and transfusion, lower nasogastric intubation rate, and earlier ambulation and recovery of intestinal function than the PDS group (P<0.05). CONCLUSIONS NAC/IDS is less invasive than PDS, and offers the advantages regarding optimal cytoreduction rate, intraoperative blood loss, and postoperative recovery, without significantly impairing the survival compared with PDS in treating patients with stage IIIC or IV EOC. Therefore, NAC/IDS may be a valuable treatment alternative for EOC patients.

Abstract
Abstract The aim of this study was to assess the clinical value of preoperative blood levels of HE4 as a predictor of overall survival in patients with ovarian cancer and to validate previous data of HE4 and the ROMA algorithm including HE4 and CA125 in discriminating benign and malignant ovarian tumors. Experimental design The preoperative plasma levels of HE4 and CA125 were analyzed with ELISA in 312 patients with adnexal lesions. Tumors were classified as benign (n= 206), borderline (i.e. low malignant potential tumors) (n= 25), and well (n= 14), moderately (n= 15), and poorly (n= 51) differentiated malignant. Results In univariate Cox regression analyses high levels (dichotomized at the median) of HE4, CA125, increased age (continuous variable), advanced-stage of disease 2–4, histological grade 3 and non-optimal tumor debulking at primary surgery were all significantly associated with shorter overall survival. A multivariate Cox regression model including pre-operative available covariates HE4 and CA125 both dichotomized at median in addition to age as continuous variable showed that high levels of HE4 was an independent prognostic marker for worse prognosis HR 2.02 (95% CI 1.1-3.8). In postmenopausal women the ROMA algorithm gave the highest AUC of 0.94 (95% CI, 0.90-0.97) which was higher than the separate markers HE4 AUC 0.91 (95% CI 0.86-0.95) and CA125 AUC 0.91(95% CI 0.87-0.96). Conclusions High concentration of plasma HE4 is an independent preoperative marker of poor prognosis in patients with ovarian cancer. The algorithm ROMA discriminates in postmenopausal women between malignant and benign tumors with an AUC of 0.94.

Abstract
BACKGROUND Epithelial ovarian cancer presents at an advanced stage in the majority of women. These women require surgery and chemotherapy for optimal treatment. Conventional treatment is to perform surgery first and then give chemotherapy. However, it is not yet clear whether there are any advantages to using chemotherapy before surgery. OBJECTIVES To assess whether there is an advantage to treating women with advanced epithelial ovarian cancer with chemotherapy before cytoreductive surgery (neoadjuvant chemotherapy (NACT)) compared with conventional treatment where chemotherapy follows maximal cytoreductive surgery. SEARCH METHODS For the original review we searched, the Cochrane Central Register of Controlled Trials (CENTRAL, Issue 3, 2006), MEDLINE (Silver Platter, from 1966 to 1 Sept 2006), EMBASE via Ovid (from 1980 to 1 Sept 2006), CANCERLIT (from 1966 to 1 Sept 2006), PDQ (search for open and closed trials) and MetaRegister (most current search Sept 2006). For this update randomised controlled trials (RCTs) were identified by searching the Cochrane Central Register of Controlled Trials (CENTRAL, Issue 3, 2011) and the Cochrane Gynaecological Cancer Specialised Register (2011), MEDLINE (August week 1, 2011), EMBASE (to week 31, 2011), PDQ (search for open and closed trials) and MetaRegister (August 2011). SELECTION CRITERIA RCTs of women with advanced epithelial ovarian cancer (Federation of International Gynaecologists and Obstetricians (FIGO) stage III/IV) who were randomly allocated to treatment groups that compared platinum-based chemotherapy before cytoreductive surgery with platinum-based chemotherapy following cytoreductive surgery. DATA COLLECTION AND ANALYSIS Data were extracted by two review authors independently, and the quality of included trials was assessed by two review authors independently. MAIN RESULTS One high-quality RCT met the inclusion criteria. This multicentre trial randomised 718 women with stage IIIc/IV ovarian cancer to NACT followed by interval debulking surgery (IDS) or primary debulking surgery (PDS) followed by chemotherapy. There were no significant differences between the study groups with regard to overall survival (OS) (670 women; HR 0.98; 95% CI 0.82 to 1.18) or progression-free survival (PFS) (670 women; HR 1.01; 95% CI 0.86 to 1.17).Significant differences occurred between the NACT and PDS groups with regard to some surgically related serious adverse effects (SAE grade 3/4) including haemorrhage (12 in NACT group vs 23 in PDS group; RR 0.50; 95% CI 0.25 to 0.99), venous thromboembolism (none in NACT group vs eight in PDS group; RR 0.06; 95% CI 0 to 0.98) and infection (five in NACT group vs 25 in PDS group; RR 0.19; 95% CI 0.07 to 0.50). Quality of life (QoL) was reported to be similar for the NACT and PDS groups.Three ongoing RCTs were also identified. AUTHORS' CONCLUSIONS We consider the use of NACT in women with stage IIIc/IV ovarian cancer to be a reasonable alternative to PDS, particularly in bulky disease. With regard to selecting who will benefit from NACT, treatment should be tailored to the patient and should take into account resectability, age, histology, stage and performance status. These results cannot be generalised to women with stage IIIa and IIIb ovarian cancer; in these women, PDS is the standard. We await the results of three ongoing trials, which may change these conclusions.

Abstract
OBJECTIVES To study the role of neoadjuvant chemotherapy (NACT) followed by surgical cytoreduction in the management of advanced epithelial ovarian cancers. METHODS A prospective hospital based study of patients with advanced epithelial ovarian cancers (stage III and IV) was conducted at Gujarat Cancer & Research Institute, Ahmedabad during August 2008 to August 2010. Total 50 patients were treated with NACT followed by surgical cytoreduction and followed up till August 2010. Response to NACT, optimal cytoreduction rate and overall response rate were analyzed. RESULTS There were 43 patients (86%) with stage III disease and 7 (14%) with stage IV disease. All patients were given NACT and after NACT, complete response occurred in 17 patients (34%), 27 (54%) had partial response. Optimal surgical cytoreduction could be achieved in 36(72%) of the patients. The median follow up was 19 months. CONCLUSIONS NACT followed by surgical cytoreduction is a promising treatment strategy for the management of advanced epithelial ovarian cancers.

Abstract
OBJECTIVE The objective of this study was to describe the development and experience in resection of tumor at the porta hepatis in patients with ovarian cancer by an interdisciplinary team approach. METHODS From August 2007 to June 2009, 11 women (2 primary and 9 recurrent ovarian cancers) underwent extended cytoreductive surgery including resection of tumor at the porta hepatis by hepatobiliary surgeons. RESULTS Tumor resection at the porta hepatis was required in 7.1% of the patients (11/155) during the study period. The median tumor size of the porta hepatis was 2.0cm (range, 0.7-4cm). All visible tumors at the porta hepatis were completely resected with co-operation of hepatobiliary surgeons. Optimal cytoreduction was achieved in all patients. There was no significant morbidity related to tumor resection of the porta hepatis and mortality associated with surgery. Five of 11 patients had recurrent disease at median 8months (range, 1-13) after the surgery with a median follow-up of 8months (range, 3-21months). CONCLUSION Tumor resection at the porta hepatis is feasible with acceptable morbidities in patients with ovarian cancer by an interdisciplinary team approach with hepatobiliary surgeons. Long term follow up is needed to know the impact on survival.

Abstract
BACKGROUND Interval debulking surgery (IDS), following induction or neoadjuvant chemotherapy, may have a possible role in treating advanced epithelial ovarian cancer (stage III to IV) where primary debulking surgery is not an option. OBJECTIVES To assess the effectiveness and complications of IDS for patients with advanced stage epithelial ovarian cancer. SEARCH STRATEGY We searched the Cochrane Gynaecological Cancer Group's Specialised Register to July 2009, the Cochrane Central Register of Controlled Trials (CENTRAL) Issue 2, 2009, MEDLINE from January 1966 to June week 4 2009, and EMBASE from January 1966 to week 27 2009. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing survival of women with advanced epithelial ovarian cancer, who had IDS performed between cycles of chemotherapy after primary surgery with survival of women who had conventional treatment (primary debulking surgery and adjuvant chemotherapy). DATA COLLECTION AND ANALYSIS Two review authors independently assessed trial quality and extracted data. Searches for additional information from study authors were attempted. Meta-analysis of overall and progression-free survival (PFS) were performed using random-effects models. MAIN RESULTS Three RCTs randomising 853 women, of whom 781 were evaluated, met the inclusion criteria. Meta-analysis of three trials for overall survival (OS) found no statistically significant difference between IDS and chemotherapy alone (hazard ratio (HR) = 0.80, 95% confidence interval (CI) 0.61 to 1.06, I(2) = 58%). Subgroup analysis for OS in two trials, where the primary surgery was not performed by gynaecologic oncologists or was less extensive, showed a benefit of IDS: HR = 0.68, 95% CI 0.53 to 0.87, I(2) = 0%). Meta-analysis of two trials for progression-free survival (PFS) found no statistically significant difference between IDS and chemotherapy alone (HR = 0.88, 95% CI 0.57 to 1.33, I(2) = 83%). Rates of toxic reactions to chemotherapy were similar in both arms (risk ratio = 1.19, 95% CI 0.53 to 2.66, I(2) = 0%), but little information was available for other adverse events or quality or life. AUTHORS' CONCLUSIONS No conclusive evidence was found to determine whether IDS between cycles of chemotherapy would improve or decrease the survival rates of women with advanced ovarian cancer, compared with conventional treatment of primary surgery followed by adjuvant chemotherapy. IDS appeared to yield benefit only in patients whose primary surgery was not performed by gynaecologic oncologists or was less extensive. Data on QoL and adverse events were inconclusive.

Abstract
The current management of advanced ovarian cancer consists of aggressive primary cytoreductive surgery (PCS) followed by combination platinum based chemotherapy. Recent studies have suggested that platinum-based chemotherapy may be of benefit in patients with advanced ovarian cancer prior to cytoreductive surgery (neoadjuvant chemotherapy, NACT). The concept of NACT has not been completely validated in the treatment of ovarian cancer. This review will discuss the role of NACT in patients with advanced epithelial ovarian cancer.

Abstract
BACKGROUND Primary debulking surgery, a crucial step in the management of epithelial ovarian cancer, is not always an option in patients with advanced stage disease (stage III to IV). In some circumstances, surgery may not yield satisfactory results with residual tumour masses > 1 to 2 cm (so called suboptimal surgery). Induction or neoadjuvant chemotherapy followed by interval debulking surgery (IDS) may have an alternative role in this setting. However, the advantage of IDS compared to conventional methods is still a controversial issue. OBJECTIVES To assess the effectiveness and complications of IDS for patients with advanced stage epithelial ovarian cancer. SEARCH STRATEGY We searched the Cochrane Central Register of Controlled Trials (CENTRAL), (The Cochrane Library, Issue 2, 2008), MEDLINE (January 1966 to June 2008), EMBASE (January 1966 to June 2008), and reference lists of included studies.

DATA COLLECTION AND ANALYSIS Two review authors independently assessed trial quality and extracted data. Searches for additional information from study authors were attempted. Meta-analysis of overall and progression free survival (PFS) was performed using fixed effects models. MAIN RESULTS Three RCTs, randomising 853 women of whom 781 were evaluated, met the inclusion criteria. Overall survival (OS) showed substantial heterogeneity between trials (I(2) = 58%). Subgroup analysis for overall survival in two trials, wherein the primary surgery was not performed by gynecologic oncologists or was less extensive, showed a benefit of IDS: (relative risk) RR = 0.7 (95% confidence interval (CI): 0.5 to 0.9, I(2) = 0%). Likewise, substantial heterogeneity between two trials for PFS evaluating 702 women was also shown (I(2) =75%). Rates of toxic reactions to chemotherapy were similar in both arms (RR = 1.3, 95%CI: 0.4 to 3.6), but little information is available for other adverse events. Only one trial reported quality of life (QOL), which was generally similar in both treatment arms. AUTHORS' CONCLUSIONS No conclusive evidence was found to determine whether IDS between cycles of chemotherapy would improve or decrease the survival rates of women with advanced ovarian cancer, compared with conventional treatment of primary surgery followed by adjuvant chemotherapy.

Abstract
Low-grade serous carcinomas represent approximately 10% of all serous ovarian carcinomas. A growing body of research has demonstrated several important differences between the clinical and molecular characteristics of these tumors and those of high-grade serous ovarian carcinomas. Patients with low-grade serous ovarian tumors are diagnosed at a younger age, have a longer overall survival, and have lower response rates to conventional chemotherapy. In addition, low-grade serous ovarian carcinomas have pathologic and molecular characteristics distinct from high-grade serous carcinomas, yet similar to serous tumors of low malignant potential. This suggests a common pathogenesis and a continuum of disease from serous tumors of low malignant potential to low-grade serous carcinomas. Further study, focusing specifically on low-grade serous carcinomas, is needed to determine the role of other chemotherapeutic agents, hormonal therapy, or targeted biologic agents in the treatment of this disease.

Abstract
In this review, we summarized 14 major clinical advances in gynecology which occurred in 2008. For cervical cancer, clinical impact of HPV vaccine, prognostic value of imaging during radiotherapy, and oncologic/obstetric outcomes of fertility-sparing surgery were chosen. For uterine cancer, optimal method of adjuvant radiotherapy in intermediate-risk patients, extent of lymph node dissection, outcome of robot-assisted staging surgery, new standard chemotherapy regimen for leiomyosarcoma were selected. For ovarian cancer, recent changes in adjuvant therapy, feasibility of neoadjuvant chemotherapy, prediction of optimal secondary cytoreduction, studies on new biomarkers, advances in screening and treatment of women with BRCA mutations were included. For other cancers, the safety of sentinel lymph node dissection in vulvar cancer and chemotherapy regimens for low-risk gestational trophoblastic tumors were reviewed.

Abstract
OBJECTIVES To assess the effectiveness of interval debulking surgery (IDS) for patients with advanced stage epithelial ovarian cancer (EOC). METHODS We searched the Cochrane Central Register of Controlled Trials, Medline, EMBASE, and reference lists for randomized controlled trials (RCTs) of advanced stage EOC. The trials had to report survival of women who had primary surgery and had IDS performed between cycles of chemotherapy comparing to survival of women who had conventional treatment (primary debulking surgery and adjuvant chemotherapy). Two review authors independently assessed trial quality and extracted data. Meta-analysis of overall survival (OS) and progression-free survival (PFS) was performed using fixed effects models. RESULTS Three RCTs, involving 853 women of whom 781 were evaluated, met the inclusion criteria. OSs were substantial heterogeneity between trials (I(2)=58%). Subgroup analysis in two trials, wherein the primary surgery was not performed by the gynecologic oncologists, or was less extensive, showed benefit of IDS: hazard ratio=0.7 (95% confidence interval [CI]: 0.5 to 0.9, I(2)=0%). Substantial heterogeneity between two trials for PFS evaluating 702 women was also shown (I(2)=75%). Toxic reactions to chemotherapy were similar in both arms (RR=1.3, 95% CI: 0.4 to 3.6). Only one trial reported quality of life, which was generally similar in both treatment arms. CONCLUSIONS Our review could not conclude whether IDS would improve the survival of women with advanced EOC compared with conventional treatment. IDS appeared to yield benefit only in the patients whose primary surgery was not performed by expert surgeons.

Abstract
PURPOSE To evaluate serum C-reactive protein (CRP) as prognostic variable in patients with epithelial ovarian cancer (EOC). EXPERIMENTAL DESIGN In a multicenter study, preoperative serum CRP was evaluated in 623 patients with EOC. Results were correlated with clinical data. RESULTS Mean (SD) preoperative serum CRP was 3.6 (4.8) mg/dL. Serum CRP was significantly associated with International Federation of Gynecologists and Obstetricians stage (P < 0.001) and postoperative residual tumor mass (P < 0.001) but not with histologic grade (P = 0.1) and type (P = 0.7), patients' age (Pearson's correlation coefficient = 0.05; P = 0.2), and serum CA 125 (Pearson's correlation coefficient = 0.02; P = 0.6). Patients with platinum-resistant EOC had significantly higher CRP serum levels compared with patients with platinum-sensitive EOC [6.0 (6.6) mg/dL versus 2.8 (3.8) mg/dL; P < 0.001]. Higher International Federation of Gynecologists and Obstetricians stage (P < 0.001), presence of postoperative residual tumor mass (P < 0.001), tumor grade (P = 0.001), serum CA 125 (P = 0.03), and serum CRP (P = 0.001) were independently associated with overall survival. Patients with serum CRP < or =1 mg/dL versus >1 mg/dL had an overall 5-year survival of 82% versus 58.5% (P < 0.001). CONCLUSION Serum CRP can be seen as a novel, widely available independent prognostic variable of ovarian cancer.

Abstract
It is clear that primary debulking remains the standard of care within the treatment of advanced ovarian cancer (FIGO stage III and IV). This debulking surgery should be performed by a gynecological oncologist without any residual tumor load, or so-called "optimal debulking." Over the last decades, interest in the use of neoadjuvant chemotherapy together with an interval debulking has increased. Neoadjuvant therapy can be used for patients who are primarily suboptimally debulked due to an extensive tumor load. In this situation, based on the randomized European Organization for Research and Treatment of Cancer-Gynaecological Cancer Group trial, interval debulking by an experienced surgeon improves survival in some patients who did not undergo optimal primary debulking surgery. Based on the GOG 152 data, interval debulking surgery does not seem to be indicated in patients who underwent primarily a maximal surgical effort by a gynecological oncologist. Neoadjuvant chemotherapy can also be used as an alternative to primary debulking. In retrospective analyses, neoadjuvant chemotherapy followed by interval debulking surgery does not seem to worsen prognosis compared to primary debulking surgery followed by chemotherapy. However, we will have to wait for the results of future randomized trials to know whether neoadjuvant chemotherapy followed by interval debulking surgery is a good alternative to primary debulking surgery in stage IIIc and IV patients. Open laparoscopy is probably the most valuable tool for evaluating the operability primarily or at the time of interval debulking surgery.

Abstract
AIMS The standard treatment for advanced ovarian cancer consists of cytoreductive surgery associated with a platinum/paclitaxel-based chemotherapy. Nevertheless, there is still the question as to the extent and timing of the surgical debulking. The aim of this study was to evaluate the place of surgery in the therapeutic sequence. PATIENTS AND METHODS We reviewed data from all consecutive patients with stage IIIC and IV epithelial ovarian cancer, operated on at our institution between 1990 and 2005. Patients were divided into 2 groups, according to the position of surgery in the therapeutic sequence. Patients in group 1 received initial debulking surgery. Group 2 consisted of patients having received their first debulking after initial chemotherapy. RESULTS Two hundred and three patients were identified and frequently underwent aggressive surgery, in particular, digestive surgery with bowel resections. Perioperative mortality and morbidity rates were low (2% and 14%, respectively) and there was no difference between the groups. Overall survival in group 1 for patients with complete cytoreduction (residual disease (RD)=0), optimal surgery (RD<1cm) or sub-optimal surgery (RD>1cm) was 50%, 30% and 14%, respectively. In group 2, overall survival following complete surgery was 30%, and no long-term survival was observed when surgery was not complete at the time of interval surgery. Survival was worse for patients who had received more than 4 cycles of neoadjuvant chemotherapy. CONCLUSION This study confirms the importance of surgery in the prognosis of advanced ovarian cancer. Only the patient subgroup that underwent complete initial or interval surgery was associated with a prolonged remission. Optimal surgery with a controlled morbidity can be achieved in many cases, even if bowel resection is needed, at the time of primary debulking. In the interval cytoreductive surgery subgroup, the response to initial chemotherapy and surgery was found to be essential for prognosis.

Abstract
OBJECTIVE To evaluate the predictive value of conventional criteria for identifying surgically unresectable disease among patients with ovarian cancer undergoing initial operative intervention at tertiary referral centers employing a so-called aggressive approach to surgical cytoreduction. METHODS All patients with advanced epithelial ovarian cancer undergoing primary surgery between August 1997 and August 2006 were identified. Surgical/pathological documentation of disease extent pre/post-cytoreduction was extracted from the medical record retrospectively. All patients meeting conventional criteria for unresectable disease criteria (ascites >1000 mL, omental extension to spleen >1 cm, parenchymal liver disease >1 cm, porta hepatis involvement >1 cm, diaphragmatic disease >1 cm, carcinomatosis >1 cm, and suprarenal adenopathy >1 cm) were selected for further study. RESULTS A total of 180 consecutive patients had disease meeting conventional criteria for unresectability at =1 site(s). Optimal cytoreduction (residual disease=1 cm) was achieved in 166 patients (92.2%). Optimal resection rates according to the most common individual unresectable disease criteria were as follows: ascites >1000 mL=91.3% (116/127), carcinomatosis >1 cm=91.0% (81/89), and splenic involvement >1 cm=84.9% (45/53). For patients with ascites >1000 mL alone, optimal cytoreduction was achieved in 95.8% (46/48) of cases. Optimal resection rates according to the total number of unresectable disease sites were as follows: 1 site=95.0% (19/20), 2 sites=93.8% (61/65), 3 sites=81.5% (22/27), 4 sites=93.3% (14/15), and 5 sites=80.0% (4/5). CONCLUSIONS These data suggest that commonly accepted criteria of surgically unresectable disease for women with advanced ovarian cancer lack the necessary precision to guide clinical management. Pre-operative assessment of resectability should be made by an experienced surgical team prior to deferring the initial attempt at surgical cytoreduction.

Abstract
OBJECTIVE To evaluate the response of women with low-grade serous carcinoma of the ovary or peritoneum to platinum-based neoadjuvant chemotherapy. METHODS Using institutional databases, we identified 25 women with advanced low-grade serous carcinoma of the ovary or peritoneum treated with neoadjuvant platinum-based chemotherapy between 1989 and 2006. Demographic and clinical variables were abstracted from the medical records. Progression-free survival (PFS) and overall survival (OS) were estimated using the method of Kaplan and Meier. RESULTS Median patient age at diagnosis was 45 years (range 29-81). The majority of patients (n=19, 76%) received a combination of a taxane and platinum drug. A median of six cycles of chemotherapy was administered (range 2-16). Of the 20 patients for whom pre- and post-neoadjuvant chemotherapy CA-125 levels were available, 50% had a >50% reduction after neoadjuvant chemotherapy. However, radiographic survey of the 24 patients evaluable at the completion of neoadjuvant chemotherapy demonstrated one patient (4%) with a complete response, 21 (88%) with stable disease and 2 (8%) with progression following neoadjuvant chemotherapy. Median PFS and OS for all patients were 21.4 and 56.1 months, respectively. CONCLUSIONS The low response rate to platinum-based neoadjuvant chemotherapy observed indicates that low-grade serous carcinoma is not as responsive to conventional chemotherapy as high-grade serous carcinoma. Prospective clinical trials focused specifically on low-grade serous carcinoma are needed to make meaningful advances in the treatment of this disease.

Abstract
BACKGROUND Epithelial ovarian cancer presents at an advanced stage in the majority of patients. These women require chemotherapy and surgery for optimal treatment. Conventional treatment is to perform surgery first and then give chemotherapy. However, it is important to determine whether there is any advantage to using chemotherapy prior to surgery. OBJECTIVES To assess whether there is an advantage to treating women with advanced epithelial ovarian cancer with chemotherapy prior to debulking surgery (neoadjuvant chemotherapy) compared with conventional treatment where chemotherapy follows maximal debulking surgery. SEARCH STRATEGY RCTs were identified by searching The Cochrane Central Register of Controlled Trials (CENTRAL, Issue 3, 2006), MEDLINE (Silver Platter, from 1966 to 1st Sept 2006), EMBASE via Ovid (from 1980 to 1st Sept 2006), CANCERLIT (from 1966 to 1st Sept 2006), PDQ (search for open and closed trials) and MetaRegister (most current search Sept 2006). SELECTION CRITERIA Women with advanced epithelial ovarian cancer (Federation of International Gynaecologists and Obstetricians (FIGO) stage III-IV); randomized allocation to treatment groups which compared platinum-based chemotherapy before debulking surgery with platinum-based chemotherapy following debulking surgery. DATA COLLECTION AND ANALYSIS Data were extracted by three independent authors, and the quality of included trials was assessed by three independent authors. MAIN RESULTS One RCT was identified as meeting the inclusion criteria. This trial randomized 85 women and compared standard debulking surgery followed by eight cycles of platinum-based chemotherapy with pre-operative intra-arterial platinum-based chemotherapy and ovarian artery embolization followed by debulking surgery and seven cycles of platinum-based chemotherapy. There was no statistical difference in median overall survival (OS) between the two treatment groups. Three on-going RCTs were identified and their results are awaited. AUTHORS' CONCLUSIONS There is as yet no good evidence that neoadjuvant chemotherapy prior to debulking surgery for women with advanced epithelial ovarian cancer is superior to conventional debulking surgery and platinum-based chemotherapy.

Abstract
The objective is to assess the ability of preoperative serum CA125 levels to identify patients at high risk of suboptimal cytoreductive surgery for epithelial ovarian cancer (EOC). One hundred and thirty-two women diagnosed with EOC between 1998 and 2004, who had serum CA125 levels measured preoperatively and received primary cytoreductive surgery, were retrospectively evaluated. The value of CA125 and patient and disease characteristics to predict suboptimal cytoreduction were determined, and a prognostic scoring system, based on statistically significant variables, was created. Optimal cytoreduction was achieved in 42.7% of the women with FIGO stage III/IV EOC. The optimal cutoff point of preoperative CA125 to predict surgical outcome in this group was 330 U/mL (sensitivity 80.0%; specificity 41.5%). The area under the receiver-operating characteristic curve (AUC) for preoperative CA125 predicting suboptimal surgery in FIGO stage III/IV was 0.576 (P = 0.617). Preoperative radiologic amount of ascites and weight loss (ie, >or=10% in the last 6 months before diagnosis) were independent prognostic factors for suboptimal cytoreduction, showing an AUC of 0.76 (P < 0.001) in women with FIGO stage III/IV. A prognostic scoring system showed that the chance of suboptimal surgery was 84.6% in FIGO stage III/IV when both these factors are present preoperatively. The role of CA125 levels predicting suboptimal cytoreduction seems questionable. Instead, women with considerable weight loss and a gross amount of ascites have a higher risk of suboptimal cytoreduction. These patients may be candidates for neoadjuvant chemotherapy.

Abstract
BACKGROUND The purpose of this study was to determine if serum prealbumin could be used to objectively determine which patients could not safely undergo cytoreductive surgery. METHODS Patients with suspected ovarian cancer in a 24-month period underwent nutritional assessment during their preoperative workup and were followed for development of postoperative complications. RESULTS One hundred and eight of 114 patients underwent surgical cytoreduction. Of the 108 surgical patients, 88 patients had prealbumin levels <18 mg/dl and 24 patients had prealbumin levels <10 mg/dl. Postoperative complications increased with lower prealbumin levels. All complications occurred in group of patients with prealbumin <18 mg/dl (P=0.013). A significantly increased number of complications occurred in patients with prealbumin <10 mg/dl (61.5% vs. 6.4%, P<0.001, RR 9.6). All postoperative mortality in this series occurred in patients with prealbumin <10 mg/dl (23.1% vs. 0%, P<0.001). Patients whose prealbumin started low but was able to be raised to >10 mg/dl by TPN did not have significantly increased complications or EBL compared to patients whose initial prealbumin was >10 mg/dl (18.2% vs. 4.8%, P=0.95 and 570 vs. 600 ml, P=0.87). CONCLUSIONS Significantly more blood loss, morbidity, and mortality occurred in patients with abnormal preoperative prealbumin. This was especially true in patients with a prealbumin <10 mg/dl. With these significantly increased risks, patients with extremely poor nutritional status (prealbumin <10 mg/dl) may be better served by neoadjuvant chemotherapy with interval cytoreductive surgery if nutrition improves.

Abstract
AIMS Ovarian cancer has a very poor prognosis, with 5-year survival rates of 5-20% for advanced-stage disease. This work was designed to verify whether the neoadjuvant approach had an effect on survival in patients with advanced-stage ovarian cancer. MATERIALS AND METHODS Patients with stage III or IV disease who received neoadjuvant platinum-based chemotherapy (group 1) were compared with a group of conventionally treated patients (group 2). RESULTS Most of the patients in group 1 (76%) had partial tumoral responses after chemotherapy. Patients from group 1 (n = 42) had a median survival that was not different from that in patients from group 2 (n = 348). Patients who received platinum-based chemotherapy with taxanes had the same survival of patients who received no taxanes. CONCLUSIONS Our results showed similar responses and survival rates for patients with stage III or IV ovarian cancer treated with neoadjuvant platinum-based chemotherapy, when compared with patients who underwent primary suboptimal cytoreductive surgery. Our data therefore support the ongoing trials to determine the optimum timing of surgery for ovarian cancer.

Abstract
OBJECTIVE To summarize the existing data on interval cytoreductive surgery and neoadjuvant chemotherapy as alternative treatment strategies for patients with advanced-stage ovarian cancer. METHODS All investigational studies with evaluable survival data on interval cytoreductive surgery and neoadjuvant chemotherapy for ovarian cancer reported in the English language literature between 1989 and 2006 were systematically reviewed. RESULTS Three randomized trials and six non-randomized studies of interval cytoreduction following suboptimal initial surgery were identified. Twenty-six studies, including a total of 1336 patients, reporting on neoadjuvant chemotherapy administered in lieu of primary cytoreductive surgery were analyzed according to the survival outcome achieved, the degree of surgical effort or success, and the particular selection criteria employed to justify deferring an attempt at primary cytoreductive surgery. CONCLUSIONS Interval surgery following a concerted but suboptimal attempt at up-front cytoreduction does not appear to have an appreciable impact on survival outcome. Maximal primary cytoreductive surgery remains the standard of care for the majority of women with suspected advanced ovarian cancer. Neoadjuvant chemotherapy represents a viable alternative management strategy for the limited number of patients felt to be optimally unresectable by an experienced ovarian cancer surgical team; however, currently available data suggest that the survival outcome achievable with initial chemotherapy is inferior to successful up-front cytoreductive surgery. Additional research is needed to devise universal selection criteria for neoadjuvant chemotherapy, determine the most efficacious treatment program, and characterize the appropriate proportion of patients in which an attempt at primary surgery should be abandoned in favor of initial chemotherapy.
