Background and purpose
Treatment-induced chronic vaginal changes after definitive radio(chemo)therapy for locally advanced cervical cancer patients are reported as one of the most distressing consequences of treatment, with major impact on quality of life. Although these vaginal changes are regularly documented during gynecological follow-up examinations, the classic radiation morbidity grading scales are not concise in their reporting. The aim of the study was therefore to identify and qualitatively describe, on the basis of vaginoscopies, morphological changes in the vagina after definitive radio(chemo)therapy and to establish a classification system for their detailed and reproducible documentation.
Patients and methods
Vaginoscopy with photodocumentation was performed prospectively in 22 patients with locally advanced cervical cancer after definitive radio(chemo)therapy at 3–24 months after end of treatment. All patients were in complete remission and without severe grade 3/4 morbidity outside the vagina.
Results
Five morphological parameters, which occurred consistently after treatment, were identified: mucosal pallor, telangiectasia, fragility of the vaginal wall, ulceration, and adhesions/occlusion. The symptoms in general were observed at different time points in individual patients; their quality was independent of the time of assessment. Based on the morphological findings, a comprehensive descriptive and semiquantitative scoring system was developed, which allows for classification of vaginal changes. A photographic atlas to illustrate the morphology of the alterations is presented.
Conclusion
Vaginoscopy is an easily applicable, informative, and well-tolerated procedure for the objective assessment of morphological vaginal changes after radio(chemo)therapy and provides comprehensive and detailed information. This allows for precise classification of the severity of individual changes.
