Clinical Trial Summary

This pilot clinical trial studies how well fraction carbon dioxide (CO2) laser therapy works in treating vaginal atrophy in patients with breast cancer. Fraction CO2 laser therapy uses intense beams of light to cut, burn, or destroy tissue and may remodel vaginal tissue and direct controlled thermal damage of vaginal mucosa.

Description:

PRIMARY OBJECTIVES:

I. To demonstrate the feasibility of fractionated CO2 laser treatments in patients with breast cancer with vaginal atrophy by determining treatment completion rates and tolerability of treatment.

II. To demonstrate the efficacy of fractionated CO2 laser treatments in patients with breast cancer with vaginal atrophy as determined by improvement from baseline to post treatment in the score of the Vaginal Assessment Scale (VAS).

SECONDARY OBJECTIVES:

I. Sexual behavior/function as measured by the Sexual Experiences Scare, Global sexual satisfaction scale, Female Sexual Function Index (FSFI), and the Female Sexual Distress Scare (FSDS).

II. Other symptoms of urogenital atrophy using the Urogenital Distress Inventory (UDI).

III. Overall patient assessment of symptoms by Patient Global Impression of Improvement scale (PGI-I).

OUTLINE:

Patients undergo fractional CO2 laser therapy every 4-6 weeks for 3 treatments.

After completion of study treatment, patients are followed up at 4 weeks.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Vaginal Assessment Scale score	Using Vaginal Assessment Scale (VAS)	Baseline up to 4 weeks
Primary	Patient compliance rates	Compliance rates with treatment will be assessed.	Up to 4 weeks
Primary	Feasibility of laser treatments defined by completion rates and tolerability of treatment	Will evaluate if laser can be completed and tolerated will be used to summarize demographics and clinical characteristics.	Up to 4 weeks
Secondary	Other symptoms of urogenital atrophy using the Urogenital Distress Inventory	Descriptive statistics will be used to summarize demographics and clinical characteristics. Will either compare categorical responses from baseline to post treatment using McNemars Chi-square test or compare the change in response using a Signed Rank Test. Data will be transformed or a nonparametric test will be conducted if necessary.	Up to 4 weeks
Secondary	Sexual behavior/function as measured by the Sexual Experiences Scare, Global sexual satisfaction scale, Female Sexual Function Index, and the Female Sexual Distress Scare	Descriptive statistics will be used to summarize demographics and clinical characteristics. Will either compare categorical responses from baseline to post treatment using McNemar?s Chi-square test or compare the change in response using a Signed Rank Test. Data will be transformed or a nonparametric test will be conducted if necessary.	Up to 4 weeks
