RESEARCH QUESTION: What is the effect of myomectomy in women with uterine fibroids on time to live birth and other reproductive outcomes?
DESIGN: This was a monocentric retrospective cohort study of 311 women with fibroids, of whom 165 eventually received myomectomy and 146 remained on expectant management. To assess the primary outcome time to live birth, a Cox proportional hazards model with a time-varying covariate for myomectomy was used. In the sensitivity analyses, this was combined with an approach to account for confounders via a cloning/censoring/weighting that aimed to emulate a randomized controlled trial.
RESULTS: Notable differences in baseline characteristics between the myomectomy and expectant management group were fibroid size (fibroid >7 cm: myomectomy 48%; expectant management 15%) and whether the patient had fibroid-related complaints (myomectomy 85%, expectant management 67%). The adjusted hazard ratio for the effect of myomectomy compared with expectant management on live birth was 1.26 (95% CI 0.87-1.81). Sensitivity analyses yielded similar results, but secondary outcomes showed that women remaining on expectant management had more often received assisted reproductive technology (63%) compared with those who eventually received myomectomy (38%).
CONCLUSIONS: The study did not find a significant difference in time to live birth after myomectomy compared with expectant management in women with fibroids and a wish to conceive, despite more, larger and more symptomatic fibroids in the myomectomy group. The results after myomectomy encourage the execution of a randomized controlled trial in women with large (symptomatic) fibroids not or minimally distorting the intrauterine cavity, and infertility or a desire to conceive.
