Mahalingam et al in the Journal of Maternal-Fetal & Neonatal Medicine reported the risk of preterm birth among women with uterine fibroids who underwent myomectomy versus those who did not prior to pregnancy. In this retrospective cohort study, the team evaluated 290 women with a viable intrauterine pregnancy and history of uterine fibroids and compared two groups: 70 with history of a prior myomectomy and 220 who did not undergo myomectomy and had at least 1 fibroid of size 5 cm or more detected at less than 21 weeks’ gestation. The team found that women who underwent prior myomectomy versus those who did not were more likely to deliver preterm < 37 weeks gestation (35% vs 21%; P = .02) and deliver a mean 1.4 weeks earlier (36.3±3.6 vs 37.7±3.7 weeks gestation; P = .02). Patients with history of myomectomy had a higher C-section rate (88% vs 53%, P < 0.001). However, when the authors controlled for late preterm pre-labor C-sections recommended by physicians in the myomectomy cohort (n=5), the difference in preterm birth was not significant between the groups.
Lee et al reported that MRI can potentially predict the benefit of GnRH-agonist treatment prior to for large fibroids. In this retrospective analysis published in Acta Radiologica, 30 patients with large uterine fibroids received GnRH agonist prior to uterine artery embolization (UAE) with MRI evaluation before and after treatment. Indications for GnRH-agonist treatment (monthly 3.75 mg leuprolide acetate injections) included intramural or subserosal fibroids > 10 cm in diameter or pedunculated submucosal fibroids > 8 cm, as well as contrast enhancement observed on T1-weighted (T1W) images. Mean maximum fibroid diameter was 11.1 + 1.9 cm and mean number of GnRH-agonist injections received was 2.8. Signal intensity (SI) of the predominant fibroid on T2-weighted (T2W) images was referenced to the SI of the rectus abdominus muscle (F/R). For predicting a volume reduction rate of the large fibroid of >50%, the optimal cut-off value of F/R was 2.58 (sensitivity 80%, specificity 80%). Likewise, large fibroids with a volume rate reduction of <30% had an optimal cut-off volume of 1.69 (sensitivity 100%, specificity 70%). From a clinical perspective, both surgeons and radiologists could use SI of the predominant fibroid on T2W to predict response to GnRH agonist pretreatment.
