Feto-maternal outcomes of pregnancy complicated by ovarian sex-cord stromal tumor: a systematic review of literature. [Review] - 2014

Sex-cord stromal tumors (SCSTs) are rare ovarian cancers and their behavior during pregnancy is not well understood. To evaluate the maternal and fetal outcomes of pregnancy complicated by ovarian SCST, a systematic literature search was conducted in PubMed/MEDLINE using entry key words "pregnancy" and each type of ovarian SCST ("sex cord stromal tumor, " "granulosa cell tumor, " "thecoma, " "Sertoli-Leydig cell tumor, " or "gynandroblastoma") between 1955 and 2012 that identified 46 cases eligible for the analysis. Clinical characteristics, pregnancy outcome, tumor characteristics, and survival outcomes were evaluated. Serious adverse events were defined as complications related to the SCST that resulted in severe morbidity or mortality for mother, fetus, or both. The most common histology was granulosa cell tumor (22.0%), followed by thecoma (18.6%) and Sertoli-Leydig cell tumor (8.5%). Abdomino-pelvic pain (45.7%), palpable mass (30.4%), and virilization (26.1%) were the three most common symptoms. The majority were stage I (76.1%), tumor size <15cm (64.9%), and underwent unilateral adnexectomy (80.4%). Fetal conservation surgery was seen in 54.3%. Most cases had live births (78.3%) at full term (60.9%). Among cases proceeded expectant delay of delivery (45.7%), most cases resulted in live birth (95.2%) with median expectant interval of 20.7 weeks. Maternal and/or fetal serious adverse events (SAEs) were observed in 41.3% with maternal shock/hemoperitoneum being the most common complication (13.0%). Logistic regression test identified younger age (<30 versus >30, 73.3% versus 26.7%, odds ratio [OR] 11.7, 95%CI 1.35-101, p=0.026), large tumor (size >15cm versus <15cm, 64.9% versus 35.1%, OR 10.0, 95%CI 1.29-26.2, p=0.004), and advanced-stage (stages II-IV versus I, 76.1% versus 23.9%, OR 5.82, 95%CI 2.05-48.9, p=0.022) as risk factors of increased SAE. Overall survival of patients diagnosed with ovarian SCST during pregnancy was comparable to ovarian SCST not related to pregnancy (5-year rate, stages I and II-IV, 100% and 70.0%, respectively). In conclusion, although the majority of cases resulted in live birth, ovarian SCST-complicated pregnancy falls into the category of high-risk pregnancy. Risk factors for SAE identified in our study will help to guide strategic management of pregnancy complicated by ovarian SCST. Copyright � 2013 Elsevier Ireland Ltd. All rights reserved.
