NCT07296237

Brief Summary

The goal of this observational study is to learn how radiotherapy for anal cancer affects the vaginal and sexual health of women after treatment. The study will also look at whether the radiation dose to the vagina is linked to the level of vaginal problems. The main questions this study aims to answer are:

  • How many women develop moderate or severe narrowing of the vagina after radiotherapy?
  • Is there a link between the radiation dose and vaginal problems?
  • How do vaginal changes affect sexual health and daily life?
  • What care and support do women receive, and how satisfied are they with this support? Participants are women aged 18 years or older who were treated with chemotherapy and radiotherapy for anal cancer and are 6 to 36 months after treatment. Participants will: Have a gynaecological examination to check the vagina for changes such as narrowing, stiffness, bleeding, or scarring Complete online questionnaires about quality of life and sexual health Answer questions about use of vaginal dilators, hormone treatment, and sexual counselling Allow researchers to analyse their radiotherapy scans to measure how much radiation the vagina received Some participants will also take part in a telephone interview about their experience with guidance and support after treatment The study will include about 80 participants across three Danish hospitals. About 20 participants will take part in the interview part of the study. The results from this study may help improve how doctors and nurses prevent, detect, and treat vaginal and sexual problems after radiotherapy for anal cancer. This may lead to better support and quality of life for future patients.

Outcome Measures

Primary Outcomes (1)

  • Prevalence of moderate to severe vaginal stenosis after radiotherapy for anal cancer

    This outcome measures how many participants have moderate or severe narrowing of the vagina after treatment for anal cancer. Vaginal stenosis will be assessed during a gynaecological examination using a standard clinical grading system CTCAE v. 5.

    Single assessment at study visit, 6 to 36 months after completion of chemoradiotherapy

Secondary Outcomes (5)

  • Gynecological findings at examination after radiotherapy for anal cancer

    Single assessment at study visit, 6 to 36 months after completion of chemoradiotherapy

  • Patient-reported sexual health and quality of life after radiotherapy for anal cance

    Single assessment at study visit, 6 to 36 months after completion of chemoradiotherapy

  • Use of vaginal dilators, hormone treatment, and sexual counselling after radiotherapy

    Single questionnaire assessment at study visit, 6 to 36 months after completion of chemoradiotherapy

  • Radiation dose to the vagina and its relation to vaginal stenosis

    Retrospective analysis of radiotherapy plans after study inclusion

  • Patient satisfaction with guidance on gynecological and sexual side effects

    Single telephone interview within 3 months after study inclusion
