Medical therapies for heavy menstrual bleeding in women with uterine fibroids: a retrospective analysis of a large commercially insured population in the USA.

OBJECTIVES: To report patterns and patient characteristics associated with initiation of and persistence with medical therapies for uterine fibroid-related heavy menstrual bleeding. DESIGN: Retrospective cohort study. SETTING: US commercial insurance claims database. POPULATION: 41 561 women aged 18-54 years with uterine fibroids and heavy menstrual bleeding who initiated medical therapies from January 2000 through December 2013. METHOD: Multinomial logistic regression was used to assess patient characteristics associated with initiation and persistence. Cox proportional hazards regression was used on propensity score-matched cohorts to examine change from index medication. MAIN OUTCOMES MEASURES: Initiation of and persistence with four first-line medical therapies: short- and long-acting reversible contraceptive steroids, leuprolide acetate, and tranexamic acid. RESULTS: Most women (79.4%) took short-acting reversible contraceptive steroids as first-line therapy (index medication), whereas 9.5%, 8.5%, and 2.7% used long-acting reversible contraceptive steroids, leuprolide acetate, and tranexamic acid, respectively. During follow-up, 16 594 women (39.9%) switched to nonindex medication (18.4%) or procedural treatment (81.6%). In comparison with women taking short-acting steroids, those receiving long-acting steroids were less likely to switch [hazard ratio (HR) 0.84, 95% CI 0.79-0.91], whereas women taking leuprolide acetate (HR 2.44, 95% CI 2.27-2.62) or tranexamic acid (HR 1.44, 95% CI 1.26-1.65) were more likely to switch. Older age, emergency department visits, anaemia, and inflammatory disease diagnoses at baseline were associated with increased probability of discontinuing the index medication or switching to another therapy. CONCLUSIONS: Women with uterine fibroid-related heavy menstrual bleeding were more likely to persist with their initial therapy of long-acting reversible contraceptive steroid compared with other medical options. TWEETABLE ABSTRACT: 80% women with fibroid-related heavy menstrual bleeding use SARC, but LARC users are more persistent.

Prospective assessment of survival, morbidity, and cost associated with lymphadenectomy in low-risk endometrial cancer.

OBJECTIVE: Since 1999, patients with low risk endometrial cancer (EC) as defined by the Mayo criteria have preferably not undergone lymphadenectomy (LND) at our institution. Here we prospectively assess survival, sites of recurrence, morbidity, and cost in this low risk cohort. METHODS: Cause-specific survival (CSS) was estimated using the Kaplan-Meier method and compared using the log-rank test. Complications were graded per the Accordion Classification. Thirty-day cost analyses were expressed in 2010 Medicare dollars. RESULTS: Among 1393 consecutive surgically managed cases, 385 (27.6%) met inclusion criteria, accounting for 34.1% of type I EC. There were 80 LND and 305 non-LND cases. Complications in the first 30 days were significantly more common in the LND cohort (37.5% vs. 19.3%; P<0.001). The prevalence of lymph node metastasis was 0.3% (1/385). Over a median follow-up of 5.4 years only 5 of 31 deaths were due to disease. The 5-year CSS in LND and non-LND cases was 97.3% and 99.0%, respectively (P=0.32). None of the 11 total recurrences occurred in the pelvic or para-aortic nodal areas. Median 30-day cost of care was $15,678 for LND cases compared to $11,028 for non-LND cases (P<0.001). The estimated cost per up-staged low-risk case was $327,866 to $439,990, adding an additional $1,418,189 if all 305 non-LND cases had undergone LND. CONCLUSION: Lymphadenectomy dramatically increases morbidity and cost of care without discernible benefits in low-risk EC as defined by the Mayo criteria. In these low-risk patients, hysterectomy with salpingo-oophorectomy alone is appropriate surgical management and should be standard of care.
