Systemic lupus erythematosus is associated with an increased frequency of spontaneous preterm births: systematic review and meta-analysis.

OBJECTIVE: Preterm birth is one of the most frequent complications of pregnancy in women with systemic lupus erythematosus. The high indicated preterm birth proportion due to hypertensive disorders of pregnancy and/or fetal growth restriction is well known, and preventive measures and screening for early detection are performed. The risk of spontaneous preterm birth is less well recognized. This study aimed to determine the proportions of spontaneous and indicated preterm birth in pregnancies of women with systemic lupus erythematosus. DATA SOURCES: A systematic literature search using Pubmed, Embase, Web of Science, and Google Scholar was performed in June 2021. STUDY ELIGIBILITY CRITERIA: Studies in pregnant women with systemic lupus erythematosus reporting spontaneous and indicated preterm birth rates were selected. Original research articles published from 1995 to June 2021 were included. METHODS: Quality and risk of bias of the included studies were assessed using the Newcastle-Ottawa quality assessment scale. To estimate the pooled event rates and 95% confidence intervals, meta-analysis of single proportions with a random-effects model was performed. RESULTS: We included 21 articles, containing data of 8157 pregnancies in women with systemic lupus erythematosus. On average, 31% (95% prediction interval, 0.14-0.50) of the pregnancies resulted in preterm birth, including 14% (95% prediction interval, 0.04-0.27) spontaneous and 16% (95% prediction interval, 0.03-0.35) indicated preterm birth. CONCLUSION: In pregnant women with systemic lupus erythematosus, spontaneous and indicated preterm birth proportions are high. This information should be applied in (prepregnancy) counseling and management in pregnancy. The knowledge obtained by this meta-analysis paves the way for further research of associated risk factors and development of interventions to reduce spontaneous preterm birth in systemic lupus erythematosus pregnancies.

Serous endometrial intra-epithelial carcinoma: an observational study.

BACKGROUND: Serous endometrial intra-epithelial carcinoma is described as a malignant, superficial spreading lesion with risk of extra-uterine spread at time of diagnosis, and poor outcome. OBJECTIVE: To evaluate the surgical management of patients with serous endometrial intra-epithelial carcinoma and its impact on oncologic outcomes and complications. METHODS: This Dutch observational retrospective cohort study evaluated all patients diagnosed with pure serous endometrial intra-epithelial carcinoma in the Netherlands, between January 2012 and July 2020. The pathological examination was reviewed by two pathologists with expertise in gynecological oncology. Clinical data were obtained when the diagnosis was confirmed. Primary outcome is progression-free survival, secondary outcomes are duration of follow-up, adverse events related to surgery, and overall survival. RESULTS: A total of 23 patients from 13 medical centers were included, of whom 15 (65.2%) presented with post-menopausal blood loss. In 17 patients (73.9%) the intra-epithelial lesion was present in an endometrial polyp. All patients underwent hysterectomy, of whom 12 patients (52.2%) were surgically staged. None of the staged patients showed extra-uterine disease. Two patients received adjuvant brachytherapy. There were no recurrences of disease (median follow-up duration of 35.6 months (range 1.0-108.6) and no disease-related deaths in this cohort. CONCLUSION: In patients with serous endometrial intra-epithelial carcinoma, median progression-free survival reached nearly 3 years and no recurrences have been reported. Our results do not endorse World Health Organization 2014 advice to treat serous endometrial intra-epithelial carcinoma as high-grade, high-risk endometrial carcinoma. Full surgical staging might possibly lead to overtreatment.

Serous endometrial intraepithelial carcinoma (SEIC): Current clinical practice in The Netherlands.

INTRODUCTION: Serous endometrial intraepithelial carcinoma (SEIC) is a rare diagnosis, defined as an intraepithelial lesion with cells identical to serous type endometrial carcinoma. SEIC is considered to be potentially metastatic, however clear and robust data on prognosis are lacking, potentially leading to variability in clinical management. OBJECTIVE: The aim is to establish the opinion of gynecologists on the optimal management of patients with SEIC. METHODS: An online questionnaire with 15 multiple choice questions was sent to all gynecologists with expertise in gynecological oncology in 19 expert centers in The Netherlands. RESULTS: A total of 24 gynecologists participated. The majority of respondents (n = 18/24, 75%) do not consult a guideline regarding the treatment of SEIC. In current practice, 14 of the 24 respondents perform surgical staging in women with SEIC (58.3%) while seven choose hysterectomy with bilateral salpingo-oophorectomy (29.2%), and three (12.5%) have no firm preference. Eleven of the 14 respondents who perform a surgical staging procedure believe that this is certainly the optimal treatment. The majority of respondents have no firm opinion on whether lymph node sampling or lymph node dissection is preferable during surgical staging (n = 15/23, 65.2%). Most respondents do not give adjuvant therapy (n = 15/24, 62.5%), 25.0% recommend brachytherapy (n = 6/24). Follow-up is for 5 years in almost all cases (n = 23/24). CONCLUSION: There is no consensus on the optimal surgical treatment and the use of adjuvant therapy for patients with SEIC. Our research team is therefore conducting a nationwide cohort study in which treatment modality, morbidity and survival will be evaluated.
