  • Human Epididymis Protein 4 in Early Diagnosis of Endometrial Cancer: A Systematic Review

    ObjectiveTo systematically review the value of human epididymis protein 4 (HE4) in early diagnosis of endometrial cancer. MethodsDatabases including The Cochrane Library (Issue 1, 2013), PubMed, MEDLINE (Ovid), CNKI, CBM and WanFang Data were electronically searched for relevant studies on HE4 versus the golden standard (pathological examination) in the diagnosis of endometrial cancer from inception to April 2013. Meanwhile, relevant journals were also manually searched. Two reviewers independently screened literature according to the inclusion and exclusion criteria, and evaluated the included studies using the QUADAS items. Then, meta-analysis was performed using RevMan 5.1 and Meta-DiSc 1.0. ResultsFinally, a total of 16 studies involving 2 299 women (1 088 endometrial cancer patients diagnosed according to the golden standard, of which, 504 with benign uterine disease and 707 with normal cervical) were included. The results of meta-analysis showed that, as for HE4 in early diagnosis of endometrial cancer (SEN=57%, 95%CI 0.54 to 0.60; SPE=92%, 95%CI 0.91 to 0.94; +LR=6.92, 95%CI 5.00 to 9.58;-LR=0.46, 95%CI 0.39 to 0.55; DOR=18.38, 95%CI 12.21 to 27.69; AUC=0.881 7). ConclusionThe current study indicates that serum HE4 is more sensitive and low specific when applied in patients with endometrial cancer, which is worth of being used in clinic. Due to the limitation of low quality of the included studies, more high quality trials are required to verify the above conclusion.

  • Adjuvant Radiotherapy for Endometrial Cancer: A Systematic Review

    Objective To assess the clinical effectiveness, safety and cost-effectiveness of adjuvant radiotherapy(RT) for endometrial cancer compared to other treatmen. Method The following electronic databases were searched: MEDLINE, EMBAS, CancerLit, CBMdisc, CNKI. The Cochrane Library (Issue 3, 2007). Correlative websites, such as ‘google’, were searched by hand. The studies included in the references of eligible studies were additionally searched RCTs of adjuvant radiotherapy before March, 2007 comparing adjuvant radiotherapy with other treatment for endometrial cancer were included. Eligible RCTs were assessed for quality by two reviewers independently: criteria of concealment of treatment, blinding, standard validity and reliability of outcome measures, withdraw rate, intention-to-treat analysis and homogeneity between centers were analyzed for each study. All data were performed by a meta-analysis. Result Seven RCTs met the inclusion criteria/ Methodological quality was level B. Five RCTs were compared adjuvant radiotherapy (external beam radiotherapy (EBRT) and /or intracavitary radiotherapy (ICRT) with other treatment, Two RCTs including one RCT was compared two different fractionation schedules for postoperative vagina high-dose-rate(HDR) irradiation in endometrial carcinoma the other RCT was compared two different radiotherapy method (pelvic radiotherapy and vagina radiotherapy vs vagina radiotherapy) for endometrial carcinoma. No survival different were identified; none of the studies was powered enough to show a survival benefit. But who received RT had fewer local (pelvic and/or vagina) recurrences compared to women not receiving RT. Adverse effects is found more often in RT than in not RT, there is less localrecurrences in combined radiotherapy (pelvic radiotherapy and vagina radiotherapy) than in vagina radiotherapy. lowdose vagina radiotherapy had few vagina shortening than high-dose radiotherapy, there are the same 5-overall surviva, local recurrences and distant recurrences. Conclusions Adjuvant radiotherapy for endometrial can cer can better control local recurrences than observation for postoperative endometrial cancer. Effects about overall survival, distant recurrences and disease-free survival are similar; low-dose vagina radiotherapy has few vagina shortening than high-dose radiotherapy, there are the same 5-years overall survival, local recurrences and distant recurrences for endometrial cancer, there is less local recurrences in combined radiotherapy (pelvic radiotherapy plus vagina radiotherapy) than in vagina radiotherapy for endometrial cancer; postoperative high-dose brachytherapy can get good cost-effectiveness; Effect of adjuvant radiotherapy for overall survival and disease-free survival of endometrial carcinoma are needed to further assessed by rigorously designs, randomized, double-blind, placebo-controlled trials adjuvant radiotherapy for endometrial carcinoma.

  • Clinical Effectiveness and Safety of Laparoscopy versus Laparotomy for Endometrial Cancer: A Meta-Analysis

    Objective To assess the clinical effectiveness and safety of laparoscopy versus laparotomy for endometrial cancer. Methods The databases such as The Cochrane Library, PubMed, EMbase, Ovid, CNKI, WanFang Data, and VIP were searched to collect the randomized control trials (RCTs) about the clinical effectiveness and safety of laparoscopy and laparotomy for endometrial cancer. The retrieval time was from January 1998 to September 2012. Two reviewers independently screened the literature according to the inclusive and exclusive criteria, extracted the data, and assessed the methodological quality of included studies. Then the meta-analysis was performed by using RevMan 5.0 software. Results A total of 10 RCTs involving 6 993 patients were included. Meta-analysis showed that, compared with laparotomy, laparoscopy had lesser amount of intraoperative bleeding, lower decrease of hemoglobin before and 1-day after operation, shorter time of both waiting for postoperative gas and hospital stay, lower incidence of postoperative complications, longer operation time, and higher incidence of intraoperative complications. Additionally, there were no differences between the 2 groups in the number of pelvic and para-aortic lymph nodes removed during operation, as well as the postoperative recurrence and mortality rates in 3-5 year follow-up. Conclusion Compared with laparotomy, laparoscopy shows lesser amount of intraoperative bleeding, lower decrease of hemoglobin before and 1-day after operation, shorter time of both waiting for postoperative gas and hospital stay, lower incidence of postoperative complications. But laparotomy shows lower incidences of intraoperative complications, and shorter operation time. Both operations are similar in the number of pelvic and para-aortic lymph nodes removed during operation, as well as the postoperative recurrence and mortality rates in 3-5 year follow-up. For quantity limitation and low methodological quality of included studies, this conclusion still needs to be further proved by performing more high-quality and large scale RCTs.

  • Effects of estrogen receptor α and β on proliferation of endometrial cancer cells

    Objective To explore the role of estrogen receptor alpha (ERα) and estrogen receptor beta (ERβ) in estrogen-induced proliferation of endometrial cancer, and explore whether metformin inhibits the proliferation of endometrial cancer cells through ERα and ERβ. Methods Stable transfected Ishikawa cells were constructed by lentivirus. The effects of down-regulated ERα and ERβ on estrogen-induced Ishikawa cell proliferation were detected by methyl thiazolyl tetrazolium assay. The effects of down-regulated ERα and ERβ on estrogen-induced Ishikawa cell cycle were detected by flow cytometry. In addition, quantitative real-time polymerase chain reaction and Western blotting assays were used to detect changes in the expression of cyclinD1 and P21 involved in cell cycle regulation. The effects of down-regulated ERα and ERβ on estrogen-induced Ishikawa cell proliferation were observed by adding metformin to estrogen treatment. Results Down-regulation of ERα inhibited the proliferation and cell cycle of Ishikawa cells (P<0.05). Down-regulation of ERα also inhibited the expression of cyclinD1 and promoted the expression of P21 (P<0.05). Down-regulation of ERα counteracted the effect of estrogen-induced cell proliferation, cell cycle, and the expression changes of cyclinD1 and P21 (P<0.05). Down-regulation of ERβ promoted the proliferation and cell cycle of Ishikawa cells (P<0.05). Down-regulation of ERβ also promoted the expression of cyclinD1 and inhibited the expression of P21 (P<0.05). Down-regulation of ERβ enhanced the effect of estrogen-induced cell proliferation, cell cycle, and the expression changes of cyclinD1 and P21 (P<0.05). Metformin inhibited the proliferation of estrogen-induced Ishikawa cells (P<0.05), while in the down-regulated ERα Ishikawa cells or down-regulated ERβ Ishikawa cells, the inhibition of metformin on Ishikawa cells disappeared (P<0.05). Conclusions ERα may promote estrogen-induced proliferation of endometrial cancer cells, while ERβ may inhibit estrogen-induced proliferation of endometrial cancer cells. In addition, ERα and ERβ may also mediate the inhibitory effect of metformin on endometrial cancer cells.
