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.
【摘要】 目的 探讨子宫腺肉瘤早期的临床表现、影像学特征、组织病理学以及治疗和预后。 方法 对2006年—2010年病理诊断为子宫腺肉瘤的4例青年女性患者进行回顾性分析。 结果 子宫腺肉瘤占同期子宫肉瘤的6.8％（4/58），患者平均发病年龄为40岁，均未绝经。患者均有阴道不规则流血，B型超声示最大1例肿物直径为11 cm，其余结节直径平均约1.5 cm。1例患者的CA125水平高于正常。术后随访期间所有患者身体状态良好，无复发。 结论 子宫腺肉瘤恶性程度较低，如能及时治疗，预后较好。【Abstract】 Objective To investigate the clinical manifestations, imaging features, histopathology, treatment and prognosis of uterine adenosarcoma. Methods The clinical data of four young female patients with uterine adenosarcoma collected from 2006 to 2010 were analyzed retrospectively. Results Uterine adenosarcoma accounted for 6.8% in uterine sarcoma (4/58). All patients were not menopausal, with the average onset age of 40 years old. Abnormal vaginal bleeding were seen in all patients. The diameter of the largest nodule was 11 cm, and the average of the others was 1.5cm approximately in B-ultrasound image. The value of CA125 increased in one patient. During the follow-up period, all patients survived without tumor recurrence. Conclusion Uterine adenosarcoma is a low-grade malignancy. Timely treating may lead to a good prognosis.
ObjectivesTo systematically review the perinatal outcomes after laparoscopic myomectomy versus transabdominal myomectomy.MethodsPubMed, Web of Science, Elsevier, The Cochrane Library, CNKI, VIP and WanFang Data databases were searched from inception to July 2017, to collect randomized controlled trials or cohort studies comparing the perinatal outcomes after laparoscopic myomectomy and transabdominal myomectomy. Two reviewers independently screened literature, extracted data and assessed the risk of bias of include studies. Meta-analysis was then performed by RevMan 5.3 software.ResultsEight randomized controlled trials, twenty-one cohort studies involving 4357 patients were included. The results of meta-analysis showed that: the premature birth rate (OR=0.60, 95%CI 0.38 to 0.95, P=0.03) in the laparoscopic myomectomy was lower than that in the laparotomy group. However, the rate of uterine rupture during pregnancy (OR=3.19, 95%CI 1.29 to 7.89, P=0.01) in the laparoscopic myomectomy was higher than that in the laparotomy group. There were no significant differences between two groups in the myoma residual (OR=1.00, 95%CI 0.37 to 2.65, P=0.99), recurrence (OR=0.92, 95%CI 0.68 to 1.25, P=0.60), abortion (OR=0.90, 95%CI 0.63 to 1.28, P=0.56), ectopic pregnancy (OR=1.11, 95%CI 0.54 to 2.26, P=0.78), pregnancy rate (OR=1.06, 95%CI 0.89 to 1.27, P=0.52), cesarean (OR=0.82, 95%CI 0.57 to 1.19, P=0.31), and pregnancy complications (OR=0.84, 95%CI 0.45 to 1.59, P=0.60).ConclusionsCurrent evidence shows that there are no significant differences between two groups in the myoma residual, myoma recurrence, abortion, ectopic pregnancy, pregnancy rate, cesarean and pregnancy complications. While the rate of uterine rupture during pregnancy in the laparoscopic myomectomy is higher than that in the laparotomy group, the premature birth rate after operation in the laparoscopic myomectomy is lower and shorter than that in the laparotomy group. Due to the limited quantity and quality of the included studies, more high quality studies are required to verify the above conclusion.
Objective To provide evidence for establ ishing a health care system for pregnant women after disasters by evidence-based evaluation on the comparison of programs in different countries of the world. Methods We electronically searched The Cochrane Library (Issue 2, 2008), MEDLINE (1966 to June 2008), EMbase (1984 to June 2008), VIP ( 1989 to June 2008), CBM ( 1978 to June 2008), Wangfang database (1997 to June 2008), CNKI (1994 to June 2008) and handsearched Journals such as Chinese Journal of Obstetrics and Gynecology to identify l iteratures and guidel ines on pregnant women healthy care system after calamity. The qual ity of l iteratures and guidel ines was assessed. Results A total of 293 studies were searched, of which 25 studies were identified with the focuses on the consequence of pregnancy, development of fetus and first-aid of injuries of pregnant women. We found the studies on pregnant women’s health care were l imited, and most of them were retrospective and cohort studies, which was related to the paroxysmal ity, rarity and complexity of the disaster.? Conclusions The high proportion of pregnant women among displaced persons underscores the importance of examining how behavioral changes and difficulties in access to health care influencing the maternal and infant health, which needs comprehensive planning and arrangement.
