BackgroundWomen with BRCA1 and BRCA2 mutation carriers are at substantially elevated risk of developing ovarian cancer. The aim of the meta-analysis is to clarify the role of risk-reducing salpingo-oophorectomy (RRSO) to reduce ovarian cancer risk and mortality in women with BRCA 1 and BRCA 2 mutation carriers.MethodsPubmed, Medline and Scopus were searched to select English-language articles. Two investigators independently extracted characteristics and results of selected studies. Articles were included only if prospective and if absolute numbers of ovarian cancer and death events were available or derivable from the test. Pooled hazard ratio (HR) with 95% confidence interval (CI) was calculated using fixed effects model.ResultsMeta-analysis of 3 prospective studies demonstrated a significant risk reduction of ovarian cancer with RRSO in BRCA 1 and BRCA 2 mutation carriers, as well as benefit in all-causes mortality incidence.ConclusionsIt may be justified to recommend RRSO to reduce ovarian cancer risk and all-causes mortality in women with a mutation in BRCA 1 and BRCA 2.

Although the optimal treatment of gynecological PEComas is controversial, surgical resection remains the cornerstone. The use of adjuvant treatment is warranted in high risk patients to increase disease control. A multidisciplinary approach should be key in treatment decision-making regarding gynecological PEComas.

BACKGROUND.: Vaccination against Epstein-Barr virus (EBV), inducing an antibody response to the envelope glycoprotein gp350, might protect EBV-negative children with chronic kidney disease from lymphoproliferative disease after transplantation. METHODS.: A phase I trial recruited children with chronic kidney disease to two successive cohorts given three injections of 12.5 microg (n=6) and 25 microg (n=10) recombinant gp350/alhydrogel vaccine over 6 to 8 weeks. RESULTS.: One in each cohort acquired wild EBV before the week 28 evaluation. Both doses were similarly immunogenic, inducing an IgG response in all 13 evaluable patients. Neutralizing antibodies were detected in four recipients (1/4 in the 12.5 microg and 3/9 in the 25 microg cohort). Median time from first vaccination to transplantation was 24 weeks. Immune responses declined rapidly and were unlikely to affect posttransplant events. DISCUSSION.: The vaccine was immunogenic but a prolonged vaccine schedule up to time of transplantation or improved adjuvants are required in future trials to reduce posttransplant EBV load and risk of lymphoproliferative disease.
