Uterine fibroids, the most common type of tumor among women of
reproductive age are often associated with symptoms and a reduce quality
of life (Stewart et al. BJOG 2017;124:1501-12). Hysterectomy has been
traditionally the primary approach for the management of symptomatic
fibroids after unsuccessful medical treatment. In symptomatic women who
do not want to undergo hysterectomy, myomectomy and uterine-artery
embolization (UAE) are therapeutic options, but solid evidence on the
cost-effectiveness is lacking (Gupta et al. Cochrane Database Syst Rev
2012;5:CD005073).
The FEMME trial, a multicenter randomized controlled trial compared
myomectomy with UAE in 254 premenopausal women with symptomatic uterine
fibroids wishing to preserve their uterus and fertility (Manyoda et al.
N Engl J Med 2020;383:440). Dikshyanta and co‐workers conducted an
economic evaluation alongside. UAE was dominated by myomectomy. UAE was
associated with higher mean costs (£645 and £352 over two and four year
horizon) and lower health-related quality-of-life (difference of 0.09
after both two and four years) when compared with myomectomy.
Sensitivity analyses did not influenced the results.
Although the authors should be complimented for conducting this economic
valuation, the results should be interpreted cautiously. A substantial
number of women amendable for the FEMME trail were not recruited due to
preference for a particular treatment. The analysis was conducted
according to intention-to-treat principle but of the participants
randomly assigned only (98/127) 77% women underwent embolization and
(105/127) 83% underwent myomectomy. Furthermore, 82% of the myomectomy
procedures were open abdominal procedures and only 18% laparoscopic.
Noteworthy, after four years up to 50% of response of the participants
on the health-related quality-of-life questionnaires were missing, a
significant percentage.
The cost-effectiveness of different treatment is influenced by different
factors, including settings, population, time horizon, costs,
perspectives, method of analysis and assumptions made for analysis,
making generalizability of the findings and comparison with other
studies difficult. Due to restriction of the framework used, it was not
possible to take patient
preference and possible preferences of women for a less invasive
procedure into account. Although AUE was dominated by myomectomy, less
costly and provided better health-related quality-of-life scores, the
differences after 4 years follow-up were relatively small and both
treatments significantly improved health-related quality of life.
Despite the reported limitations, Dikshyanta and co‐authors must be
highly complimented for conducted this economic evaluation. This study
provides valuable information. Clinicians are able to better inform
women with symptomatic fibroids wishing to avoid a hysterectomy and to
help them in the decision making process, including the
costs-effectiveness of the procedures. As women may add value to UAE as
a non-surgical procedure, women should have the options to choose
between both procedures.
It may be of value to continue to follow-up the participants to
establish if the reported differences between the treatment methods
still persist after a longer period. Further research on the
cost-effectiveness of (new) treatment methods, like MRgHIFU for
symptomatic uterine fibroids, especially in women wishing to avoid
hysterectomy and preserve their fertility, are still required.
