DW-MRI predictive factors for radiation-induced vaginal stenosis in patients with cervical cancer

Barriers to and facilitators of adherence to pelvic floor muscle exercises and vaginal dilator use among gynecologic cancer patients: a qualitative study

Objective

Women with gynecologic cancer may suffer from pelvic floor dysfunction (PFD). Before radiotherapy, prehabilitation with pelvic floor muscle exercises (PFME) and vaginal dilator (VD) might prevent it and foster sexual life. This study aims to explore the experience of gynecologic cancer patients getting external beam radiation treatments regarding barriers to and facilitators of adherence to a prehabilitation program to prevent PFD.

Methods

This qualitative research with thematic content analysis included 11 women with gynecologic cancer and different levels of adherence to PFME and VD. Participants were interviewed based on a semi-structured script. The information was analyzed manually, assisted with Nvivo12® software, and triangulated with open coding.

Results

High self-motivation, desire to improve their health, symptoms of improvement, availability of time, the desire to resume sexual life, and the support of the partner were facilitators of adherence. The instructional exercise audio, clarity of the information, and closer communication with the physical therapist were also valued. The main barriers were general malaise secondary to oncological treatments, forgetfulness, lack of time, misinformation, lack of coordination with the treatment team, discomfort with the VD, and a feeling of shame. Feedback from the attending physician was a facilitator when present or a barrier when absent.

Conclusion

These barriers and facilitators should be considered when designing and implementing preventive programs with PFME and VD. Behavioral counselling should consider the desire to remain sexually active; in such cases, including the partner in the therapeutic process is appraised. Otherwise, the focus should be on benefits for maintenance of pelvic floor function.

Diagnostic Methods for Vaginal Stenosis and Compliance to Vaginal Dilator Use: A Systematic Review

BACKGROUND

Vaginal stenosis (VS) is a common side effect of pelvic radiotherapy for gynecological cancer in women. It has a high incidence variability, likely due to unstandardized and subjective assessment methods. Furthermore, even though the worldwide standard treatment for VS is vaginal dilation, low compliance rates have been noted.

AIM

To evaluate the parameters used to diagnose VS and to assess whether the lack of an objective measure of VS hampers vaginal dilator use.

METHODS

A systematic review in accordance with the PRISMA reporting guidelines was conducted. PubMed, EMBASE, and Web of Science databases were searched. Randomized trials and prospective, retrospective, and cross-sectional studies published from January 2011 to February 2020 were included.

OUTCOMES

The main outcome of this study was a review of the published literature on assessment methods for VS and compliance to vaginal dilator use.

RESULTS

Of the 28 articles obtained, only 7 used objective methods to measure the vaginal volume. 3 studies have demonstrated patient's concern with VS development and showed a high compliance to dilator use, whereas others reported several barriers to dilator use.

CLINICAL IMPLICATIONS

Lack of an objective assessment method can be a predisposing factor for uncertain VS incidence rates and impair compliance to vaginal dilator therapy, leading to long-term VS and sexual dysfunction.

STRENGTHS & LIMITATIONS

This is the first systematic review on the heterogeneity of VS evaluation methods and compliance to vaginal dilator use. All studies were comprehensively evaluated by 2 reviewers. The limitations included the heterogeneity of the study designs and the unstandardized criteria used to classify stenosis or to evaluate compliance to dilator use. Although 3 well-known databases were used, the inclusion of more data sources could have increased the number of publications included in this review.

CONCLUSION

VS is frequently diagnosed using subjective parameters. Few unstandardized objective methods are used to evaluate this condition. Regarding compliance to vaginal dilator use, there was a high dropout rate during follow-up and no consensus on starting time or ideal usage. Haddad NC, Soares Brollo LC, Pinho Oliveira MA, et al.
