Overview
Brief Summary
In this randomized controlled trial, the investigators will assess the difference in mean patient-reported pain scores and sexual function between women with gynecologic or breast cancers experiencing dyspareunia (painful intercourse) who are assigned to vaginal dilator use with vaginal moisturizer (Intervention Group, n = 29) compared to vaginal moisturizer alone (Control Group, n = 29) over 16 weeks.
Detailed Description
Between 2012 and 2016, approximately 94,000 women were diagnosed with a gynecologic cancer annually and over 1.2 million women with breast cancer between 2013 and 2017. It is well known that gynecologic and breast cancers, and their treatments including surgery, adjuvant chemotherapy and endocrine therapy, and radiation, result in significant effects on the female reproductive system which can lead to sexual dysfunction. In the U.S., sexual dysfunction among gynecologic oncology patients has been reported to be as high as 90%, and over 70% among breast cancer patients. Patients who receive chemotherapy and/or endocrine therapy commonly experience dyspareunia, vaginal dryness, and challenges with desire and orgasm due to a low estrogen state. In fact, among patients with breast cancer, unaddressed sexual side effects from adjuvant endocrine therapy are one reason for early discontinuation. Hysterectomy and oophorectomy, including for ovarian cancer risk-reduction, can cause similar physical symptoms in addition to psychologic effects like anxiety related to sexual intercourse.

Eligibility Criteria
Inclusion Criteria
- •Patients 18 years or older
- •English or Spanish speaking
- •Patients currently or previously treated for:
- •Gynecologic cancer (surgery, chemotherapy, adjuvant vaginal brachytherapy)

- •Current desire for penetrative sexual activity
- •Endorsement of at least one of the following in the last 6 months:
- •Dyspareunia during penetrative sexual activity
- •Reported sensation of penetrative object (partner's penis, sex toy) not fitting in the vagina
- •Avoidance of penetrative sexual activity due to fear of pain
Exclusion Criteria
- •Patients with prior primary or upfront pelvic radiation
- •Patients with whole pelvic radiation at any time

Outcomes
Primary Outcomes
Difference in Mean Patient-Reported Pain Scores During Sexual Activity
Time Frame: Up to 16 weeks
The difference in mean patient-reported pain scores will be calculated, during penetrative sexual activity before and after randomization to vaginal dilator use with vaginal moisturizer or vaginal moisturizer alone. Pain scores will be assessed using a 10cm vial analog scale (VAS), in which 0 indicates no pain and 10 indicates most pain (worst outcome).
Secondary Outcomes
- Difference in Mean Patient-Reported Pain Scores During Speculum Exam(Up to 16 weeks)
