Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Application of vaginal oestriol topical cream to prevent vaginal stenosis in women receiving radiotherapy for gynecological, rectal and anal malignancies.
Patient will commence the study drug 2 weeks post completion of pelvic radiotherapy treatment along with instructions for use and/or demonstration of oestriol applicator use by the clinician or clinic nurse.
Participants will be instructed to insert the applicator with a dose of 0.5 mg of the study drug Oestriol 0.1% (1mg per g topical cream) to the top of the vagina daily for the first two weeks and then twice weekly for the rest of the intervention period (12 months application of oestriol).
Information about compliance with the intervention will be collected at scheduled visits (1, 3, 6,9, 12 month after start of oestriol) using the Adherence and Disruption
Questionnaire.

Outcomes
Primary outcome [1] 328444 0
Feasibility, compliance and acceptability of the use of vaginal oestriol, as measured by adherence and disruption questionnaire (ADQ). This will be assessed as a composite outcome.
Timepoint [1] 328444 0
12 months post end of radiotherapy
Primary outcome [2] 328445 0
The incidence of stenosis as measured by the LENT-SOMA scale on the basis of clinical assessment.
Timepoint [2] 328445 0
12 months post end of radiotherapy
Primary outcome [3] 328446 0
Safety - measured using the serum levels of oestradiol and FSH in blood tests taken at regular intervals.
Timepoint [3] 328446 0
Assessed at every treatment appointment up to 12 months post end of radiotherapy
Secondary outcome [1] 399032 0
Sexual function and vaginal symptoms - measured by the Sexual-function-Vaginal changes Questionnaire (SVQ). This will be assessed as a composite outcome.
Timepoint [1] 399032 0
12 months post end of radiotherapy
Secondary outcome [2] 399033 0
Health-related quality of life – patient reported outcome measures (FACT-G)
Timepoint [2] 399033 0
12 months post end of radiotherapy
Secondary outcome [3] 401015 0
Safety – measured by the collection and analysis of Serious Adverse Events and Adverse Events.
Timepoint [3] 401015 0
Assessed at every treatment appointment up to 12 months post end of radiotherapy, or 4 weeks after last study treatment if patients discontinues due to Adverse Event. Assessed via study-specific form including CTCAE grading.

Safety/efficacy
Statistical methods / analysis
For this phase II pilot, based on Simon’s two-stage design, 30 patients provide 80% power with 95% confidence to rule out a 25-30% stenosis rate in favour of a 7-10% with the use of vaginal oestriol.
Summary measures will include frequencies and proportions presented with their corresponding 95% confidence intervals. Comparisons of proportions will be performed using chi-squared or exact tests (e.g., conditional binomial) and continuous outcomes will be analyzed by using t-tests or suitable non-parametric methods if appropriate. For binary outcomes logistic regression analysis will be employed where adjustment for prognostic factors is mediated.
Stenosis free survival will be analyzed using time-to-event methods including the log-rank test and Cox proportional hazards regression models. Kaplan-Meier survival curves will be constructed for graphical display. Actuarial event-free survival rates will also be calculated with suitable 95% confidence intervals.
