Male and Female Sexual Dysfunction in Pediatric Cancer Survivors.

BACKGROUND

Pediatric cancer survivors suffer indirect long-term effects of their disease; however, there is a paucity of data regarding the effect of pediatric cancer survivorship on sexual function.

AIM

To assess the prevalence and risk factors associated with sexual dysfunction among pediatric cancer survivors.

METHODS

Pediatric cancer survivors were recruited to complete an online survey using the Female Sexual Function Index (FSFI) or the International Index of Erectile Function (IIEF-5), both validated questionnaires to assess female sexual dysfunction (FSD) and erectile dysfunction (ED). Patient demographics, oncologic history, prior treatment, and sexual habits were also queried. Logistic regression was used to evaluate risk factors for sexual dysfunction, and Mann-Whitney U test was used to identify factors associated with individual domains of the FSFI.

OUTCOMES

The main outcome measures were FSFI and IIEF-5 score, which are used to diagnose FSD (FSFI<26.55) and ED (IIEF-5<22).

RESULTS

A total of 21 (72.4%) female respondents and 20 (71.4%) male respondents were sexually active and completed the survey and FSFI or IIEF-5 questionnaire, respectively. Mean (±SD) age was 23.7 (4.1) years, and average age at diagnosis was 9.1 (5.0), with no difference between genders. Overall, 25.0% (5/20) of male and 52.4% (11/21) of female pediatric cancer survivors reported sexual dysfunction (P = .11). Oncologic history and prior treatment were not associated with sexual function. Females who reported difficulty relaxing during intercourse in the last 6 months had higher odds of reporting sexual dysfunction (odds ratio: 13.6, 95% confidence interval: 1.2-151.2, P = .03). Subgroup analysis of FSFI domains found that previous radiation therapy was correlated with decreased lubrication and satisfaction during intercourse, whereas previous treatment to the pelvic region significantly reduced satisfaction and increased pain during intercourse.

CLINICAL IMPLICATIONS

Female pediatric cancer survivors have higher odds of reporting sexual dysfunction after treatment and should be screened appropriately to provide early intervention and to mitigate risk.

STRENGTH & LIMITATIONS: Our study includes validated questionnaires to assess FSD and ED and queries specific characteristics to assess their association with sexual dysfunction. However, the study is limited by sample size and its cross-sectional survey design.

CONCLUSIONS

The prevalence of female sexual dysfunction in this cohort is higher than that in the general population of equivalent-aged individuals, and clinicians should be aware of these potential long-term sequelae.
