Women undergoing hysterectomy, myomectomy have similar short-term outcomes

PHILADELPHIA – Women who underwent either hysterectomy or myomectomy had similar short-term outcomes between 6 weeks and 12 weeks after surgery despite different baseline characteristics, according to recent results from the COMPARE-UF study presented at the annual meeting of the American Society for Reproductive Medicine.

“Both hysterectomy and myomectomy can substantially improve women’s quality of life scores and substantially reduce symptom severity,” reported Wanda K. Nicholson, MD, MPH, lead investigator for COMPARE-UF and professor of general obstetrics and gynecology at the University of North Carolina at Chapel Hill.

Researchers included 1,295 women in the COMPARE-UF study who were at least 30 years old, not attempting pregnancy, and undergoing hysterectomy or myomectomy for treatment of fibroids. Overall, 727 patients underwent hysterectomy, and 568 patients underwent myomectomy.

The researchers measured QoL and symptom severity using the Uterine Fibroid Scale-QoL, the EQ-5D, and Visual Analog Scale (VAS). The UFS-QoL contained subscales for concern, activities, energy and mood, control, self-consciousness, and sexual function, while the EQ-5D had subscales for mobility, self-care, usual activities, pain or discomfort, and anxiety or depression.

After surgery, UFS-QoL overall scores were similar in both hysterectomy and myomectomy groups between 6 weeks and 12 weeks (77 vs. 76), but there was less postsurgery symptom severity in the hysterectomy group over the same time period (16 vs. 20; P less than .05). However, both groups had a significant improvement in overall UFS-QoL post surgery (hysterectomy, 31; myomectomy, 30) and in UFS-QoL symptom severity (hysterectomy, 41; myomectomy, 37), Dr. Nicholson noted. EQ-5D VAS scores also were similar in both hysterectomy and myomectomy groups after treatment (82 vs. 79), and showed a 10.9 score improvement in hysterectomy patients and an 8.6 score improvement in myomectomy patients.

“This is really important, because it shows that, regardless of which procedure that you’ve chosen, at least at short-term follow up, it appears that you will have improvement in quality of life,” she said.

When researchers analyzed the UFS-QoL subscale scores, they found patients who underwent abdominal myomectomy scored better than abdominal hysterectomy on the activities subscale (79 vs. 72; P equals .01) and energy/mood subscale (82 vs. 75; P equals .03). In examining minimally invasive procedures, Dr. Nicholson and colleagues found higher improvements in health-related QoL scores among patients undergoing minimally invasive hysterectomy (45-80 vs. 45 vs. 75), and these patients also had lower symptom severity, compared with patients who underwent myomectomy (59-13 vs. 58-21).

“At least at the short-term follow-up, we think that some of that difference that we see in minimally invasive procedures vs. nonminimally invasive may be in part due to women’s perceptions or what their expectations are having minimally invasive surgery, and how they might feel in the short-term follow-up period,” said Dr. Nicholson.

These similar short-term outcomes occurred even though there were significant differences in baseline patient characteristics for the hysterectomy and myomectomy groups, with women undergoing hysterectomy being significantly younger (40 years) than patients undergoing hysterectomy (45 years). Differences also were significant between hysterectomy and myomectomy groups in the percentage of patients who were white (50% vs. 41%; P less than .01), African-American (38% vs. 41%; P less than .01) or other races (12% vs. 18%; P less than .01). There also were significant differences in baseline body mass index between hysterectomy (31 kg/m²) and myomectomy (29 kg/m²) groups.

Patients in both groups further differed in presurgery quality-of-life (QoL) scores.

Women in the hysterectomy group had lower presurgery overall QoL (44 vs. 50), greater symptom severity (60 vs. 52), and lower VAS (69 vs. 73) scores, compared with the myomectomy group (P less than .05). This difference continued in the UFS-QoL subscale scores, where women in the hysterectomy group had significantly lower scores in the concern (38 vs. 45), activities (46 vs. 52), energy/mood (45 vs. 51), control (48 vs. 52), self-consciousness (41 vs. 50), and sexual function (45 vs. 50) subscales, compared with women in the myomectomy group (P less than .05). The researchers used propensity scoring to adjust for baseline characteristics, and inverse propensity weighting to adjust for potential confounding in the multivariate analysis.
