  • Effectiveness and Safety of Paclitaxel Liposomes and Carboplatin for Ovarian Cancer: A Systematic Review

    Objective To assess the clinical effectiveness and safety of paclitaxel liposomes and carboplatin for ovarian cancer. Methods The databases such as The Cochrane Library, PubMed, EMBASE, CNKI and CBM were searched to collect all randomized control trials (RCTs) about the clinical effectiveness and safety of paclitaxel liposomes and carboplatin for ovarian cancer. Literatures were screened according to the inclusive and exclusive criteria, the data were extracted, the methodological quality of the included studies was assessed in line with Cochrane Handbook 5.0.1, and Meta-analysis was performed by using RevMan 5.0.24 software. Results Three RCTs involving 214 patients were included. Meta-analysis showed that compared with the paclitaxel plus carboplatin group, the paclitaxel liposomes plus carboplatin group didn’t show significant differences in the total effective rate (P=0.62), while it was obviously superior in reducing the adverse events, such as muscle and joint pain (Plt;0.000 01), peripheral neurotoxicity (P=0.04), nausea or vomiting (P=0.000 2), facial blushing (P=0.03) and rashes (P=0.003). But there were no significant differences between the two groups in trichomadesis, dyspnea, diarrhea, bellyache and blood system abnormalities. Conclusion As current clinical evidences shows, the paclitaxel liposomes and carboplatin in treating ovarian cancer is as effective as the paclitaxel and carboplatin, and it can reduce some of the adverse reactions. Therefore, the paclitaxel liposomes and carboplatin is available for ovarian cancer as a new, safe and effective treatment. Due to small scale and low quality of the included studies, this conclusion has to be further proved with more high-quality, large-scale, and double-blind RCTs.

  • Systematic Review of Paclitaxel Intensive Therapy for Ovarian Epithelial Cancer

    Objective To evaluate the efficacy and the adverse reactions of intensive therapy compared with conventional therapy. Methods We searched the Cochrane Central Register of Controlled Trials (Issue 3, 2008), MEDLINE (January 1980 to June 2008), EMbase (1984 to June 2008), CBM-disc (January 1980 to June 2008) and CNKI (1994 to June 2008) to get all the randomized control trials (RCTs) about paclitaxel intensive versus conventional therapy for ovarian cancer. We used RevMan 5 to perform meta-analysis. Results Six RCTs involving 572 patients were included. Metaanalysis showed the efficacy of intensive therapy and conventional therapy was similar. There were no significant differences in response rate (RR 1.06, 95%CI 0.94 to 1.20), median survival time, survival rate, median progression free survival and median time to progression between the two groups. When taking safety into consideration, intensive therapy significantly reduced the occurrence of grade Ⅲ or higher neutropenia (RR 0.49, 95%CI 0.35 to 0.69, Plt;0.000 1) and Grade Ⅲ or higher neuropathy (RR 0.43, 95%CI 0.24 to 0.78, P=0.006). But there were no significant differences between intensive therapy and conventional therapy in flush, grade Ⅲ or higher vomiting, anemia, leucopenia, grade Ⅲ or higher thrombocytopenia and alopecia. Conclusion Paclitaxel intensive therapy has similar efficacy and adverse reactions compared with conventional therapy in ovarian cancer. Above all, intensive therapy can reduce the incidence of grade Ⅲ or higher neutropenia and neuropathy. It is a good substitution for the conventional therapy.

  • Systematic Lymphadenectomy for Overall Survival in Epithelial Ovarian Cancer: A Meta-Analysis

    Objective To evaluate the role of systematic lymphadenectomy (SL) vs. unsystematic lymphadenectomy (USL) for improving overall survival (OS) in epithelial ovarian cancer (EOC). Methods The databases such as PubMed, EMbase, The Cochrane Library, Evidence-Based Medicine Reviews (EBMR), CBM, CNKI and VIP were searched between January 1, 1995 and December 31, 2010, the randomized controlled trials (RCTs) and observational studies on SL vs. USL in treating EOC were included. Based on Cochrane handbook, the data were extracted, the methodological quality was assessed, and then meta-analyses were conducted by using RevMan 5.0 software. Results The total 13 studies involving 22 796 patients were included, including 5 420 patients in the SL group, and the other 17 376 patients in the USL group. Two of the 13 studies were RCTs, and the other 11 were observational studies (including 2 studies retrieved from SEER data). The analyses on 2 RCTs showed that compared with USL, a) SL could not improve 5-PFS (OR=0.70, 95%CI 0.40 to 1.22, P=0.21) in early-stage EOC (FIGO I to II), but it did improve 5-PFS (OR=0.62, 95%CI 0.40 to 0.96, P=0.03) in advanced-stage EOC (FIGO III to IV); b) SL could not improve 5-OS in both early-stage EOC (OR=0.84; 95%CI 0.44 to1.58, P=0.58) and advanced-stage EOC (OR=0.93, 95%CI 0.64 to 1.37, P=0.73); and c) SL could not improve 5-OS in both early-stage (OR=0.84, 95%CI 0.44 to 1.58, P=0.58) and advanced-stage (OR=0.93, 95%CI 0.64 to 1.37, P=0.73) of EOC patients who had optimal tumor dubulking surgery. The analyses on observational studies showed that compared with USL, a) SL could not improve 5-PFS in both early-stage EOC (OR=0.38, 95%CI 0.08 to 1.74, P=0.21) and advanced-stage (OR=2.88, 95%CI 0.95 to 8.72, P=0.06) EOC; b) Whether SEER impacts were excluded or not, SL did improve 5-OS in both early-stage EOC (OR=0.54, 95%CI 0.46 to 0.63, Plt;0.000 01) and advanced-stage (OR=0.47, 95%CI 0.43 to 0.52, Plt;0.000 01) EOC; and c) For EOC patients who had optimal tumor dubulking surgery, SL could not improve 5-OS in early-stage (OR=0.32, 95% CI 0.02 to 6.19, P=0.45), but it did improve 5-OS in advanced-stage (OR=0.53, 95%CI 0.32 to 0.88, P=0.01). Conclusion These findings suggest that maybe SL can improve 5-PFS and 5-OS in EOC. However, the efficacy of SL on 5-PFS and 5-OS is still undetermined, so more relevant studies are required for further investigating the role of SL in EOC.

  • Ovulation Induction and Risk of Ovarian Cancer: A Systematic Review

    Objective To systematically assess literature regarding the relationship between ovulation induction and the risk of ovarian cancer. Methods We searched MEDLINE, EMbase, The Cochrane Library, CBM and CNKI (from inception to Feb, 2012). Cohort or case-control studies were identified according to the inclusion and exclusion criteria. Then the quality of the included studies was assessed, and the data was extracted. Meta-analysis was performed by RevMan 5.0 software. The incorporated RR (relative risk) and 95%CI (confidence interval) of the included cohort studies and incorporated OR (odds ratio) and 95%CI of case-control studies were calculated, respectively. Results Four cohort studies and four case-control studies were included. Result of meta-analysis on cohort studies showed ovulation induction didn’t increase the risk of ovarian cancer (RR=1.07, 95%CI 0.81 to 1.42, P=0.63). Besides, result of meta-analysis on case-control studies showed ovulation induction was not associated with the incidence of ovarian cancer (OR=1.28, 95%CI 0.78 to 2.08, P=0.33). But the risk of borderline ovarian tumors increased when compared with general population controls (OR=1.71, 95%CI 1.05 to 2.79, P=0.03). Conclusion Ovulation induction does not increase the risk of ovarian cancer, but may relate to the incidence of borderline ovarian cancer. However, more high-quality studies, especially perspective cohort studies are required because of the limited quantity of the included studies.

  • Evidence-Based Treatment for A Patient with Relapsed Ovarian Cancer

    Objective To make an individualized therapeutic regimen for a patient with stage III relapsed ovarian cancer guided by evidence-based medicine.Methods According to the clinical problems this patient showed and the PICO (patient, intervention, comparison and outcome) principle, the best clinical evidence associated with relapsed ovarian cancer was retrieved and evaluated. Results The current evidence showed that the relapsed ovarian cancer with platinum resistance tended to be treated by pharmacotherapy. Consequently, on the basis of combining the recommended guidelines, randomized controlled trials (RCTs), systematic reviews or meta-analyses on RCTs, clinical experience from doctors and willingness of patient, the regimen of Irinotecan plus Pegylated Liposomal Doxorubicin for interventional chemotherapy was recommended for this patient. After three courses of the treatment, the disease got some relieved; the medical team would like to keep conducting the same regimen for another six to eight courses, and the follow-up visit was undergoing. Conclusion For patients with relapsed ovarian cancer with platinum resistance, an individualized therapeutic regimen under the guidance of evidence-based methods can not only improve the therapeutic efficacy but also guide both doctors and patients to take the indeterminate risk of medicine.

  • HER-2/neu Status and Post-Operative Survival in Epithelial Ovarian Carcinoma: A Meta-analysis

    Objective To use a meta-analysis method to establish quantitatively the association between the HER-2/neu gene amplification/enhanced protein expression status and the 5-year post-operative survival rate or median survival time in women with epithelial ovarian carcinoma. Methods  We searched and screened Chinese and English literature published since 1989 to collect all retrospective cohort studies on the prognostic significance of HER-2/neu status in this population. The survival data were analyzed using Ludwig’s centered signed rank and the DerSimonian-Laird method. Results In total, 25 studies involving 3 251 patients were included. HER-2/neu was positive in 27.1% (95%CI 0 to 54.8%) of patients, which was not related to the pathological stage, type or grade of epithelial ovarian carcinoma. In HER-2/neu positive cases, the median survival time was shortened by 0.65 years, and the 5-year survival rate was lowered. The hazard ratio (HR) for mortality was 1.22 (95%C 1.09 to 1.36). By subgroup analysis, HER-2/neu protein expression was found to be most significant in prognostic assessment. Patients with a b positive value of HER-2/neu had an increased HR for the 5-year survival; and platinum-based chemotherapy was demonstrated to be less effective in HER-2/neu positive ovarian carcinoma. Conclusion In gynecological oncology, it is reasonable to measure HER-2/neu as a routine pathological marker to predict a patient’s prognosis and to determine the most appropriate adjuvant chemotherapy regimen.

  • Topotecan for Recurrent Ovarian Cancer: A Systemic Review

    Objective To assess the clinical efficacy, safety and cost-effectiveness of topotecan for recurrent epithelial ovarian cancer. Methods We searched MEDLINE (1966 to 2005), EMbase (1989 to 2004), CancerLit (1996 to 2003), CBMdisc (1978 to 2005), CNKI (1994 to 2005), The Cochrane Library (Issue 3, 2005), The National Research Register, and the Health Technology Assessment Database (HTA). Relevant journals were also handsearched. The search was conducted on December 31, 2005. Randomize controlled trials (RCTs) comparing topotecan versus other agents for recurrent epithelial ovarian cancer were included. The quality of the eligible trials was assessed by two reviewers independently. Meta-analysis was performed. Results Four RCTs met the inclusion criteria, and the methodological quality was either level A or B. When used as second-line chemotherapy for recurrent ovarian cancer, there was no significant difference in remission rate between topotecan and paclitaxel or pegylated liposomal doxorubicin (PLD). The clinical benefit rate of topotecan was higher than that of paclitaxel or PLD. Myelosuppression was more frequent in patients in the topotecan group than those in the PLD or paclitaxel group, but it was not severe. As to cost-effectiveness analysis, topotecan was better than PLD. Conclusions The standard regimen of topotecan (intravenous 1.5 mg/m2/d for 5 consecutive days) is recommended for use in platinum-resistant and refractory ovarian cancer.
