Presentation Overview

• Well circumscribed benign masses

• Single or multiple masses

• Whirled, shiny, white, bulging, rubbery cut surface

• Vary in size up to 100 lb

• Composed of irregular bundles of cells in an extensive connective tissue matrix

• Account for up to $34B annually

Leiomyoma leio (smooth) + myo (muscle) + oma (tumor)

Epidemiology

• Cumulative Incidence of 65% to 70%

• Risk Factors:– Race in AAW

– Obesity

– Hypertension

– Pelvic infections

– Alcohol in women who drink >7 beers/week

– Parity and smoking

Who gets uterine fibroids?

Patient Centeredness

Health care that establishes a partnership among practitioners, patients, and their families (when appropriate) to ensure that decisions respect patients' wants, needs, and preferences and that patients have the education and support they need to make decisions and participate in their own care.

• Core need for health care to be:

– Safe– Effective– Patient centered– Timely– Efficient– Equitable

Provider Perspective

43-year-old G4P3 with 24-week–sized fibroid uterus, childbearing complete, HMB and bulk symptoms…

The best treatment option for you is a hysterectomy.

11

HMB=heavy menstrual bleeding.

Patient Perspective

“They viewed my uterus like it was a useless organ… They said, ‘Well, why do you want to keep it?’ …and I said, because it’s mine.”

An Altered Perception of Normal: Understanding Causes for Treatment Delay

in Women With Symptomatic Uterine Fibroids

Altered State of Normal

“…my period lasted for 30 days and it was heavy and it was horrible. I was wearing pads like the size that you get in the hospital after you have a baby, and I was so used to that happening, that at that time I didn’t call anybody because you know it was, like, ‘This is normal’.”

18

Limited Knowledge

“No, I had not. With a bachelor’s degree and a master’s degree in science and chemistry, I had not. Thinking back to anatomy and physiology classes, we talked about having babies, talked about different forms of cancer, but did they ever mention a fibroid?

“I don’t think so.”

19

Avoidance-based Coping Strategies

“…this is what you go through as a woman, and it was like every month you are going to bleed half to death and then the rest of the time you are almost okay. I just went with that… you know, it didn’t kill me, so I would just be stronger.”

20

Patient-Provider Interactions

• Pressure to obtain a hysterectomy

• Lack of discussion of treatment options

• Belittling of symptoms

• Treatment discouragement

Summary• Patient centeredness is 1 of 6 aims identified by the IOM to

address in order to elevate the quality of patient care in the United States

• Fibroids cause emotional and psychological trauma for many patients

• Despite being significantly symptomatic, women are delaying their fibroid treatment

• Many patients report negative provider interactions during their fibroid evaluation—even if they are ultimately comfortable with their care

• Approximately 50% of women in our study reported negative feelings about hysterectomy as a treatment choice

• 28% of women reported being discouraged to pursue any treatment

25

Conclusions• Better and more tailored education is needed for women

regarding fibroid symptoms, diagnosis, and treatment options

• Many women are looking for low risk/no risk treatment options and would rather continue to be severely symptomatic than accept the available treatment options

• There is a disconnect between providers and patients during fibroid counseling and, thus, an opportunity and need to optimize patient-centered care by increasing provider sensitivity and awareness of women’s values, fears, and concerns during their evaluation and by developing research aimed at understanding the health-seeking behaviors and needs of women with fibroids

• Manage signs and symptoms

• Offer sustained reduction in size of fibroids

• Preserve fertility

• Rapidly stopped excessive bleeding: 75% normalized menstrual bleeding (7 days), 50% amenorrhea (10 days)

• After 3‐month course: 90%–92% controlled excessive menstrual bleeding, 73%–75% induced amenorrhea

• Significantly reduced volume of the 3 largest fibroids– Maintained for up to 6 months after treatment cessation

Compared to GnRH agonist, UPA:• Controlled bleeding faster• Maintained fibroid volume reduction for up to 6 months• Had a better side‐effect profile

• No evidence that it leads to endometrial hyperplasia or malignancy

• Progesterone receptor modulator‐associated change

Limitations of SPRM Treatment

• Non‐responders– 20% of fibroid volume– <10% bleeding

• Intermittent use 

• Effects on surgical planes?

• Reproductive effects long term

76

SPRMs: How are they being used?

• Preoperative optimization– Improve blood count before surgery by stopping bleeding

• Control symptoms in:– Those who don’t want surgery– Those who cannot have surgery– Those close to menopause

• Potentially LONG‐TERM intermittent therapy
