Abstract
Widespread metastasis is the primary reason for the high mortality associated with ovarian cancer (OC), and effective targeted therapy for tumor aggressiveness is still insufficient in clinical practice. Therefore, it is urgent to find new targets to improve prognosis of patients. PDE4A is a cyclic nucleotide phosphodiesterase that plays a crucial role in the occurrence and development in various malignancies. Our study firstly reported the function of PDE4A in OC. Expression of PDE4A was validated through bioinformatics analysis, RT-qPCR, Western blot, and immunohistochemistry. Additionally, its impact on cell growth and motility was assessed via in vitro and in vivo experiments. PDE4A was downregulated in OC tissues compared with normal tissues and low PDE4A expression was correlated with poor clinical outcomes in OC patients. The knockdown of PDE4A significantly promoted the proliferation, migration and invasion of OC cells while overexpression of PDE4A resulted in the opposite effect. Furthermore, smaller and fewer tumor metastatic foci were observed in mice bearing PDE4A-overexpressing OVCAR3 cells. Mechanistically, downregulation of PDE4A expression can induce epithelial-mesenchymal transition (EMT) and nuclear translocation of Snail, which suggests that PDE4A plays a pivotal role in suppressing OC progression. Notably, Rolipram, the PDE4 inhibitor, mirrored the effects observed with PDE4A deletion. In summary, the downregulation of PDE4A appears to facilitate OC progression by modulating the Snail/EMT pathway, underscoring the potential of PDE4A as a therapeutic target against ovarian cancer metastasis.

Abstract
OBJECTIVES Taxane-related neurotoxicity is a frequent clinical problem but lacks postmarketing data regarding neurological disorders. This study aimed to evaluate the potential association between neurological adverse events and several taxanederived drugs via the Food and Drug Administration Adverse Event Reporting System (FAERS). METHODS Disproportionality analysis was applied to data mining of the suspected cases of neurological disorders after using different taxanes based on the FAERS data from January 2017 and December 2021. We also investigated the times to onset, fatality, and hospitalization proportions of taxanerelated neurotoxicity. RESULTS In total, 3,940 cases were screened out, which were more prevalent in elderly patients and females. Peripheral neuropathy was a common adverse event among all taxanes with relatively strong association. Generally, the median time to neurological adverse effect onset was 27 days (interquartile range, 11.0 ~ 78.0 days) following taxane regimens, and the majority of cases were detected within the first 30 days. Among cases of neurological adverse events treated with taxane, the fatality and hospitalization proportions were 6.13% and 28.63%, respectively. CONCLUSION By analyzing the FAERS data, we provided a detailed profile of neurotoxicity and different taxanes in detail in terms of clinical characteristics, time to onset, and patient outcomes.

Abstract
BACKGROUND Chemotherapy-induced peripheral neuropathy (CIPN) is a common therapeutic complication affecting cancer patients' quality-of-life. We evaluated clinical characteristics, demographics, and lifestyle factors in association with CIPN following taxane treatment. METHODS Data were extracted from the electronic health record of 3387 patients diagnosed with a primary cancer and receiving taxane (i.e., paclitaxel or docetaxel) at Vanderbilt University Medical Center. Neuropathy was assessed via a validated computer algorithm. Univariate and multivariate regression models were applied to evaluate odds ratios (ORs) and 95% confidence intervals (CIs) of CIPN-associated factors. RESULTS Female sex (OR = 1.28, 95% CI = 1.01-1.62), high body-mass index (BMI) (OR = 1.31, 95% CI = 1.06-1.61 for overweight, and OR = 1.49, 95% CI = 1.21-1.83 for obesity), diabetes (OR = 1.66, 95% CI = 1.34-2.06), high mean taxane dose (OR = 1.05, 95% CI = 1.03-1.08 per 10 mg/m2), and more treatment cycles (1.12, 95% CI = 1.10-1.14) were positively associated with CIPN. Concurrent chemotherapy (OR = 0.74, 95% CI = 0.58-0.94) and concurrent radiotherapy (OR = 0.77, 95% CI = 0.59-1.00) were inversely associated with CIPN. Obesity and diabetes both had a stronger association with docetaxel CIPN compared to paclitaxel, although interaction was only significant for diabetes and taxane (p = 0.019). Increased BMI was associated with CIPN only among non-diabetic patients (OR:1.34 for overweight and 1.68 for obesity), while diabetes increased CIPN risk across all BMI strata (ORs were 2.65, 2.41, and 2.15 for normal weight, overweight, and obese, respectively) compared to normal-weight non-diabetic patients (p for interaction = 0.039). CONCLUSIONS Female sex, obesity, and diabetes are significantly associated with taxine-induced CIPN. Further research is needed to identify clinical and pharmacologic strategies to prevent and mitigate CIPN in at-risk patient populations.

Impact of Value Frameworks on the Magnitude of Clinical Benefit: Evaluating a Decade of Randomized Trials for Systemic Therapy in Solid Malignancies. Curr Oncol 2021; 28:4894-4928.

Abstract
In the era of rapid development of new, expensive cancer therapies, value frameworks have been developed to quantify clinical benefit (CB). We assessed the evolution of CB since the 2015 introduction of The American Society of Clinical Oncology and The European Society of Medical Oncology value frameworks. Randomized clinical trials (RCTs) assessing systemic therapies for solid malignancies from 2010 to 2020 were evaluated and CB (Δ) in 2010–2014 (pre-value frameworks (PRE)) were compared to 2015–2020 (POST) for overall survival (OS), progression-free survival (PFS), response rate (RR), and quality of life (QoL). In the 485 studies analyzed (12% PRE and 88% POST), the most common primary endpoint was PFS (49%), followed by OS (20%), RR (12%), and QoL (6%), with a significant increase in OS and decrease in RR as primary endpoints in the POST era (p = 0.011). Multivariable analyses revealed significant improvement in ΔOS POST (OR 2.86, 95% CI 0.46 to 5.26, p = 0.02) while controlling for other variables. After the development of value frameworks, median ΔOS improved minimally. The impact of value frameworks has yet to be fully realized in RCTs. Efforts to include endpoints shown to impact value, such as QoL, into clinical trials are warranted.

Abstract
Importance The Gynecologic Cancer InterGroup (GCIG) recommended that progression-free survival (PFS) can serve as a primary end point instead of overall survival (OS) in advanced ovarian cancer. Evidence is lacking for the validity of PFS as a surrogate marker of OS in the modern era of different treatment types. Objective To evaluate whether PFS is a surrogate end point for OS in patients with advanced ovarian cancer. Data Sources In September 2016, a comprehensive search of publications in MEDLINE was conducted for randomized clinical trials of systematic treatment in patients with newly diagnosed ovarian, fallopian tube, or primary peritoneal cancer. The GCIG groups were also queried for potentially completed but unpublished trials. Study Selection Studies with a minimum sample size of 60 patients published since 2001 with PFS and OS rates available were eligible. Investigational treatments considered included initial, maintenance, and intensification therapy consisting of agents delivered at a higher dose and/or frequency compared with that in the control arm. Data Extraction and Synthesis Using the meta-analytic approach on randomized clinical trials published from January 1, 2001, through September 25, 2016, correlations between PFS and OS at the individual level were estimated using the Kendall τ model; between-treatment effects on PFS and OS at the trial level were estimated using the Plackett copula bivariate (R2) model. Criteria for PFS surrogacy required R2 ≥ 0.80 at the trial level. Analysis was performed from January 7 through March 20, 2019. Main Outcomes and Measures Overall survival and PFS based on measurement of cancer antigen 125 levels confirmed by radiological examination results or by combined GCIG criteria. Results In this meta-analysis of 17 unique randomized trials of standard (n = 7), intensification (n = 5), and maintenance (n = 5) chemotherapies or targeted treatments with data from 11 029 unique patients (median age, 58 years [range, 18-88 years]), a high correlation was found between PFS and OS at the individual level (τ = 0.724; 95% CI, 0.717-0.732), but a low correlation was found at the trial level (R2 = 0.24; 95% CI, 0-0.59). Subgroup analyses led to similar results. In the external validation, 14 of the 16 hazard ratios for OS in the published reports fell within the 95% prediction interval from PFS. Conclusions and Relevance This large meta-analysis of individual patient data did not establish PFS as a surrogate end point for OS in first-line treatment of advanced ovarian cancer, but the analysis was limited by the narrow range of treatment effects observed or by poststudy treatment. These results suggest that if PFS is chosen as a primary end point, OS must be measured as a secondary end point.

Abstract
Medical treatment of ovarian cancer is based on chemotherapy. Most patients, regardless of the initial stage of their disease, will need to be treated (grade A). Standard treatment relies on a carboplatin and paclitaxel combination (grade A). For advanced diseases (stage I-IIA1 or IIIB à IV), the addition of an antiangiogenic treatment with bevacizumab to the chemotherapy, followed by a maintenance for 15 months should be proposed as it allows better disease control (grade A). For patients with somatic or germline BRCA mutations and disease stage III or IV, olaparib is recommended as maintenance treatment for 24 months (grade B, but olaparib had not the French approval as first-line treatment at the time of the present recommendation editing). No other targeted therapy or immunotherapy has yet been proven effective at the initial phase of ovarian cancer treatment. The treatment of rare tumors with a special histology must be discussed in a specialized multidisciplinary meeting of the network of rare malignant tumors of the ovary (TMRO) labeled by the INCa.

Abstract
Background Progression-free survival (PFS) has been adopted as the primary endpoint in many randomized controlled trials, and can be determined much earlier than overall survival (OS). We investigated whether PFS is a good surrogate endpoint for OS in trials of first-line treatment for epithelial ovarian cancer (EOC), and whether this relationship has changed with the introduction of new treatment types. Methods In a meta-analysis, we identified summary data [hazard ratio (HR) and median time] from published randomized controlled trials. Linear regression was used to assess the association between treatment effects on PFS and OS overall, and for subgroups defined by treatment type, postprogression survival (PPS) and established prognostic factors. Results Correlation between HRs for PFS and OS, in 26 trials with 30 treatment comparisons comprising 24,870 patients, was modest (r2 = 0.52, weighted by trial sample size). The correlation diminished with recency: preplatinum/paclitaxel era, r2= 0.66; platinum/paclitaxel, r2= 0.44; triplet combinations, r2= 0.22; biologicals, r2= 0.30. The median PPS increased over time for the experimental (Ptrend = 0.03) and control arms (Ptrend = 0.003). The difference in median PPS between treatment arms strongly correlated with the difference in median OS (r2 = 0.83). In trials where the control therapy had median PPS of less than 18 months, correlation between PFS and OS was stronger (r2 = 0.64) than where the median PPS was longer (r2 = 0.48). Conclusions In EOC, correlation in the relative treatment effect between PFS and OS in first-line platinum-based chemotherapy randomized controlled trials is moderate and has weakened with increasing availability of effective salvage therapies.

Abstract
Background Ovarian neoplasm is a kind of high risky cancer among female. This paper assessed the efficacy and safety of twelve therapies and figured out the superior chemotherapeutic drug for ovarian cancer through network meta-analysis (NMA). Method Eligible randomized controlled trials (RCTs) were retrieved from electronic databases. Primary outcomes concerning efficacy, overall survival (OS) and progression-free survival (PFS), were presented as hazard ratio (HR) and the associated 95% credible interval(CrI), while outcomes concerning safety were assessed by odds ratio (OR) and the corresponding 95% CrI. Surface under the cumulative ranking curve (SUCRA) was calculated under each survival and safety outcome in order to show the rankings of tested therapies. Result Electronic databases such as PubMed and Embase were searched to finally obtain 19 eligible studies of 16290 patients. In accordance of primary outcomes, when it came to 3-y PFS, paclitaxel/epirubicin/carboplatin (Pa/E/Ca) and pegylated liposomal doxorubicin/ paclitaxel/ carboplatin (PLD/Pa/Ca) were preferred compared to carboplatin (Ca) (HR= 0.80, 95% CrI= 0.67-0.96; HR= 0.83, 95% CrI= 0.69-0.99). According to 5y-PFS, Pa/E/Ca was notably better than Ca (HR= 0.80, 95% CrI= 0.65-0.99). As to adverse effects, Ca was superior to Pa/E/Ca in neuropathy (HR=0.05, 95% CrI=0.02-0.19). Pa/E/Ca showed high rankings in 3y-PFS (SUCRA=0.749), 5y-OS (SUCRA=0.738) and 5y-PFS (SUCRA=0.798) while (PLD/Pa/Ca) in 3y-OS (SUCRA=0.737), 5y-OS (SUCRA=0.687) and 5y-PFS (SUCRA=0.712). Besides, Pa/E/Ca ranked the third with a SUCRA of 0.661 in neutropenia. Conclusion PLD/Pa/Ca, PLD/Ca and Pa/E/Ca are highly recommended as potential therapeutically choices for patients with ovarian cancer. But considering the lack of safety data for PLD/Pa/Ca, this intervention should be taken with caution.

Jiang XP, Rui XH, Guo CX, Huang YQ, Li Q, Xu Y. A network meta-analysis of eight chemotherapy regimens for treatment of advanced ovarian cancer. Oncotarget 2017; 8:19125-19136. [PMID: 27835912 PMCID: PMC5386673 DOI: 10.18632/oncotarget.13253] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2016] [Accepted: 10/19/2016] [Indexed: 11/25/2022] Open
Abstract
This study compared the short-term efficacies of different chemotherapy regimens in the treatment of advanced ovarian cancer (AOC) through pair-wise and network meta-analyses (NMA). Randomized controlled trials (RCTs) identified in a comprehensive online literature search met our inclusion criteria. Direct and indirect evidence was combined to compare odds ratios (OR) and surfaces under the cumulative ranking curves (SUCRA) across the different treatment regimens. Twelve eligible RCTs were finally included, involving eight regimens (Paclitaxel + Carboplatin [PC], Gemcitabine + Carboplatin [GC], Carboplatin, Pegylated Liposomal Doxorubicin + Carboplatin [PLD + Carboplatin], Paclitaxel, Paclitaxel + Carboplatin + Topotecan [PC + Topotecan], Paclitaxel + Carboplatin + Epirubicin [PC + Epirubicin] and Docetaxel + Carboplatin [DC]). The NMA results revealed that in terms of overall response rate (ORR) and disease control rate (DCR), PC (ORR: OR=2.59, 95%CI=1.20-6.22; DCR: OR=2.58, 95%CI=1.05-6.82) and GC (ORR: OR=2.08, 95%CI=1.08-4.37; DCR: OR=2.43, 95%CI=1.07-5.80) were more effective against AOC than Carboplatin alone. Similarly, PC (OR=0.21, 95%CI=0.05-0.69), GC (OR=0.31, 95%CI=0.09-0.90) and PLD + Carboplatin (OR=0.22, 95%CI=0.04-0.92) slowed disease progression better than Carboplatin alone. We also found that PC was more efficacious against AOC than Carboplatin or Paclitaxel single-agent chemotherapy. Combination chemotherapy is thus recommended for AOC, and should guide subsequent drug development and treatment strategies.

Abstract
BACKGROUND Ovarian cancer (OC) is the 5th leading cause of cancer-related deaths around the world, and several chemotherapy regimens have been applied in the treatment of OC. We aim to compare toxicities of different chemotherapy regimens in the treatment of advanced ovarian cancer (AOC) using network meta-analysis. METHODS Literature research in Cochrane Library, PubMed, and EMBASE was performed up to November 2015. Eligible randomized controlled trials (RCTs) of different chemotherapy regimens were included. Network meta-analysis combined direct and indirect evidence to assess pooled odds ratios (ORs) and draw the surface under the cumulative ranking (SUCRA) curves. RESULTS Thirteen eligible RCTs were included in this network meta-analysis, including 8 chemotherapy regimens (paclitaxel + carboplatin [PC], pegylated liposomal doxorubicin [PLD] + carboplatin, carboplatin, gemcitabine + carboplatin, paclitaxel, PC + epirubicin, PC + topotecan, docetaxel + carboplatin). Gemcitabine + carboplatin regimen exerted higher incidence of anemia when compared with carboplatin and paclitaxel regimens. The incidence of febrile neutropenia of gemcitabine + carboplatin regimen was higher than that of PC, PLD + carboplatin, carboplatin, and PC + topotecan regimens. Topotecan PC + epirubicin regimen had a higher toxicity, comparing with PC, PLD + carboplatin, and PC + topotecan regimens. As for thrombocytopenia, gemcitabine + carboplatin chemotherapy regimen produced an obviously higher toxicity than PC and carboplatin. As for nausea, PLD + carboplatin chemotherapy regimen had a significantly higher toxicity than that of carboplatin chemotherapy regimen. Moreover, when compared with PC and carboplatin chemotherapy regimens, the toxicity of PC + epirubicin was greatly higher to patients with AOC. CONCLUSION The nonhematologic toxicity of PLD + carboplatin regimen was higher than other regimens, which was clinically significant for the treatment of AOC.

Abstract
We report two cases of brain metastasis in patients initially diagnosed with extremely early stage UPSC after extensive staging surgery. They did not receive either adjuvant chemotherapy or adjuvant pelvic or vaginal cuff radiation. At the same time that these patients were diagnosed with systemic metastasis, they both had a local "drop" metastasis in the vulva or the vaginal cuff. After the initial response to palliative chemotherapy, they both developed brain metastasis. The pattern of recurrence with the lack of adjuvant treatment underscores the urgent need in further evaluation of the potential benefits of adjuvant treatment, including chemotherapy and possibly in combination with radiation in this highly aggressive disease.

Neurotoxicity in ovarian cancer patients on Gynecologic Oncology Group (GOG) protocol 218: characteristics associated with toxicity and the effect of substitution with docetaxel: an NRG Oncology/Gynecologic Oncology Group study. Gynecol Oncol 2015; 136:323-7. [PMID: 25529832 PMCID: PMC4520309 DOI: 10.1016/j.ygyno.2014.12.021] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2014] [Revised: 12/11/2014] [Accepted: 12/13/2014] [Indexed: 11/22/2022]
Abstract
OBJECTIVES To describe characteristics associated with neurotoxicity (NT) in advanced ovarian cancer patients treated on Gynecologic Oncology Group 218 and examine effect of substituting docetaxel for paclitaxel in these patients. METHODS The development of NT was defined as Common Toxicity Criteria grade (G)≥1. The association between substitution with docetaxel and NT improvement was explored with generalized estimating equations adjusting for treatment cycle and NT grading at previous cycle. RESULTS Of 1864 evaluable patients, 1329 (71%) developed G≥1 NT during the study. Nearly half appeared within the first two cycles of chemotherapy, with 31% experiencing G≥2. Older patients or those with worse quality of life (QoL) scores at baseline (p<0.05) were more likely to experience NT. One-hundred-six patients received docetaxel as substitute for paclitaxel. Of them, 47 patients started with docetaxel at cycle one due to reaction to paclitaxel (n=32), fear of NT (n=4), and other reasons (n=11), whereas 59 patients switched to docetaxel during cycle 2-6 due to NT (n=32), reaction to paclitaxel (n=19), and other reasons (n=8). Although the protocol instructed otherwise, the majority continued paclitaxel despite G≥2 NT symptoms. There was no evidence that substitution with docetaxel improved NT (Odds Ratio: 1.57; 95% CI 0.98-2.54; p>0.05). Of 59 patients who switched to docetaxel, only seven (12%) discontinued taxane prior to chemotherapy completion. A roughly equal chance of worsening NT was reported on paclitaxel (6%) as on docetaxel (5%). CONCLUSIONS Age and worse QoL at baseline are associated with NT. Substitution of docetaxel did not improve NT symptoms.

Abstract
The use of taxanes in the treatment of gynecologic malignancies has expanded tremendously over the past 30 years. Both paclitaxel and docetaxel have unique microtubule stabilizing, antiangiogenic and radiation sensitizing properties that endow them with remarkable activity as chemotherapeutic agents. As research into the appropriate dose, timing, treatment interval, and response rates have been studied, they have emerged as one of the most active agents available in the treatment of gynecologic cancer. The body of research on taxanes continues to expand especially with regard to the use of taxanes in alternative formulations and in combination with newer treatments or routes of treatment. This review focuses on the development of taxanes as an effective therapy in the treatment of gynecologic cancers and data currently available in the literature regarding their efficacy. Future directions of taxane-based chemotherapy with regards to ovarian, uterine, and cervical cancers are also addressed. There is little doubt that taxane-based chemotherapy will remain an integral part of the treatment of gynecologic cancer for the foreseeable future.

Abstract
OBJECTIVE OCEANS, a randomized, placebo-controlled, phase III trial, found that adding bevacizumab to gemcitabine-carboplatin (GC) significantly improved investigator-determined progression-free survival (PFS) and objective response rate (ORR) in platinum-sensitive, recurrent ovarian cancer. To evaluate the reliability of assessment of progression and objective response per RECIST, radiologic and clinical data were assessed by an independent review committee (IRC). METHODS Radiologic images and clinical data were provided prospectively to the IRC for all randomized patients (N=484). Data were reviewed in a blinded fashion per RECIST (modified v1.0). PFS and ORR were analyzed based on the IRC assessment. Concordance between investigator- and IRC-assessed progression and objective response was assessed. RESULTS The IRC analysis demonstrated a statistically significant increase in PFS (hazard ratio [HR]=0.451; 95% confidence interval [CI]=0.351 to 0.580, p<0.0001) consistent with the benefit reported by investigators (HR=0.484; 95% CI=0.388 to 0.605, p<0.0001). The concordance rate, defined by agreement on progression status, was 74.2% overall, and comparable between treatment arms (bevacizumab, 75.2% vs. placebo, 73.1%). IRC-assessed ORR was significantly improved with bevacizumab (bevacizumab, 74.8% vs. placebo, 53.7%; p<0.0001), consistent with the investigator-assessed results. The concordance rate for objective response was 79.8% overall, and comparable between treatment arms (bevacizumab, 78.9% vs. placebo, 80.6%). CONCLUSIONS IRC-determined results were highly consistent with those determined by investigators, demonstrating that bevacizumab plus GC provides a significant improvement in PFS and ORR. These results suggest that investigators can reliably assess disease progression and objective response in recurrent ovarian cancer using RECIST, without the necessity of a full IRC review.

Abstract
BACKGROUND Epithelial ovarian cancer accounts for about 90% of all cases of ovarian cancer. Debulking surgery and six courses of platinum-based chemotherapy results in complete clinical remission (CCR) in up to 75% of cases. However, 75% of the responders will relapse within a median time of 18 to 28 months and only 20% to 40% of women will survive beyond five years. It has been suggested that maintenance chemotherapy could assist in prolonging remission. To date, there has not been a systematic review on the impact of maintenance chemotherapy for epithelial ovarian cancer. OBJECTIVES To assess the effectiveness and toxicity of maintenance chemotherapy for epithelial ovarian cancer and to evaluate the impact on quality of life (QoL). SEARCH METHODS In the original review we searched the Cochrane Gynaecological Cancer Review Group Specialised Register, The Cochrane Central Register of Controlled Trails (CENTRAL, The Cochrane Library 2009, Issue 1), MEDLINE, EMBASE, PubMed, CBMdisc, CNKI and VIP (to May 2009). We collected information from ongoing trials, checked reference lists of published articles and consulted experts in the field. For this update, the searches were extended to October 2012. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing maintenance chemotherapy with no further intervention, maintenance radiotherapy or other maintenance therapy. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for eligibility and quality and extracted data. We analysed overall survival (OS) and progression-free survival (PFS) rates as dichotomous variables. Toxicity and QoL data were extracted where present. All analyses were based on intention-to-treat (ITT) on the endpoint of survival. We also analysed data by subgroups of drugs. MAIN RESULTS We included eight trials (1644 women). When all chemotherapy regimens were combined, meta-analysis indicated no significant difference in three-, five- and 10-year OS or PFS. For five-year OS, the combined risk ratio (RR) was 1.03 (95% confidence interval (CI) 0.96 to 1.10) and for the five-year PFS, the combined RR was 1.06 (95% CI 0.97 to 1.17). Results were very similar when trials of different regimens were analysed. Comparing chemotherapy with radiotherapy, only the RR for 10-year PFS in pathological complete remission (PCR) was in favour of whole abdominal radiotherapy 0.51 (95% CI 0.27 to 1.00), while three- and five-year OS rates have no significant difference between the two groups. AUTHORS' CONCLUSIONS There is no evidence to suggest that the use of platinum agents, doxorubicin or paclitaxel used as maintenance chemotherapy is more effective than observation alone. Further investigations regarding the effect of paclitaxel used as maintenance chemotherapy are required.

Abstract
OBJECTIVE Ovarian cancer five-year survival is poor at <40%. In the absence of effective screening or new treatments, ensuring all women receive optimal treatment is one avenue to improve survival. There is little population-based information regarding the primary chemotherapy treatment that women with epithelial ovarian cancer receive. This information is essential to identify potential gaps in care. METHODS Cancer registries identified all women diagnosed with invasive epithelial ovarian cancer in Australia in 2005 (n=1192). Histopathology, chemotherapy and comorbidity information was abstracted from medical records. Multivariable logistic regression was used to identify factors associated with chemotherapy commencement, regimen, and completion. RESULTS Women >70 years (p<0.0001), those with high-grade, stage IA/IB cancers (vs. stages IC-IV, p=0.003) and those with mucinous cancers (p=0.0002) were less likely to start chemotherapy. Most treated women received platinum-based drugs (97%), but only 68% received combination carboplatin-paclitaxel and only half completed six cycles without treatment modification/delay. Approximately 19% received single-agent carboplatin: mostly those aged >70 (p<0.0001) and/or with co-morbidities (p<0.0001). Age was the strongest predictor of completing six cycles of combination therapy. CONCLUSIONS For specific patient groups, particularly older women, there is notable variation from standard treatment. Understanding how treatment variations affect survival and determining optimal regimens for these groups are research priorities.
