Prostate cancer-related sexual dysfunction - the significance of social relations in men's reconstructions of masculinity

Narrating illness experiences in a culturally acceptable manner is essential for retaining quality of life after the disruptive event of being diagnosed for prostate cancer. Psychological pressures caused by treatment side-effects such as erectile dysfunction require reinterpretation of the meanings and impacts of these side-effects on masculinity. This helps maintain coherence in men's lives. We studied how men employ culturally available discursive strategies (compensation, redefinition, recontextualisation, and normalisation) in reconstructing masculinity and sexuality. Our data consists of 22 interviews of heterosexual Finnish prostate cancer patients who had undergone surgery. The aim was to analyse the ways in which various life situations and social relations shaped and limited the use of these strategies. Discourse analysis revealed that older age, a supportive spouse, children, supportive male friends, and good health - were key elements men used in reconstructing a coherent new self-image and conception of life following cancer treatment. Men with sexually active male friends, men without families, younger men and men with new intimate relationships struggled to develop a new version of their masculinity. Being able to effectively utilise certain aspects of one's life situation in re-constructing masculinity is important in maintaining quality of life despite troublesome treatment side-effects.

Missingness in the expanded prostate cancer index short form (EPIC-26) - prevalence, patterns, and explanatory factors

BACKGROUND

Researchers and clinicians using common clinical assessments need to attend to the prevalence of missing data to ensure the validity of the information gathered. The Expanded Prostate Cancer Index Short Form (EPIC-26) is a commonly used measurement scale used for assessing patients' quality of life, but the measure lacks comprehensive analysis on missing data. We aimed to explore the quantity of missing answers in EPIC-26 and to characterize patterns and possible explanations of missing data in the survey.

METHODS

The survey sample consisted of 625 Finnish prostate cancer patients who participated in a study with a 1-year follow-up with three measurement points (0, 6, and 12 months). Descriptive statistics were used to describe the study population and missingness level. A logistic regression was performed for each EPIC domain to study factors related to missingness during the follow-up.

RESULTS

Proportions of missing answers in EPIC-26 were low (3.1-3.9%) between survey rounds. As much as 37% of patients left at least one question unanswered during their follow-up. The hormonal domain produced the most missing answers. Questions about breast tenderness/enlargement (question 13.b.), hot flashes (question 13.a.), frequency of erections (question 10.), and ability to reach orgasm (question 8.b.) were most frequently left unanswered. Higher age, lower education level, no relationship, more severe cancer, lower function scores in some EPIC domains, lower treatment satisfaction or self-rated health were associated with missingness.

CONCLUSIONS

Questions 13.b. and 13.a. might be considered female-specific symptoms, thus difficult to comprehend unless patients had already experienced side effects from androgen deprivation therapy. Questions 10. and 8.b. might be difficult to answer if the patient has been sexually inactive. To improve the measure's validity, the questionnaire's hormonal section requires additional explanation that the inquired symptoms are common treatment side effects of anti-androgen therapy; questions 8-10 require a not-applicable category for sexually inactive patients.

The expanded prostate cancer index composite short form (EPIC-26) for measuring health-related quality of life: content analysis of patients' spontaneous comments written in survey margins

INTRODUCTION

This study investigates comments that prostate cancer patients spontaneously write in the margins of the Expanded Prostate Cancer Index Short Form (EPIC-26) questionnaire. We aim to show the possible barriers that patients face while answering the survey, and to consider how these barriers may affect the response data generated. We investigate the kind of information patients' comments on EPIC-26 contain, and patients' motivations to provide this information. We also study why some EPIC domains spark more comments than others.

METHOD

We analyzed 28 pages of transcribed comments and four pages of supplementary letters from our survey participants (n = 496). Using inductive content analysis, we generated 10 categories describing the content of participants' comments, and four themes demonstrating their motives for commenting. The comments regarding each EPIC domain were quantified to discover any differences between domains.

RESULTS

The sexual domain of EPIC-26 provoked over half of all comments. Patients without recent sexual activity or desire had difficulties answering sexual function questions 8-10. The lack of instructions on whether to take erectile aid use into account when answering erectile function questions led to a diversity of answering strategies. Patients with urinary catheters could not find suitable answer options for questions 1-4. All domains sparked comments containing additional information about experienced symptoms.

CONCLUSION

Patients are mainly willing to report their symptoms, but a lack of suitable answer options causes missing data and differing answering strategies in the sexual and urinary domains of EPIC-26, weakening the quality of the response data received.

Factors related to self-rated health and life satisfaction one year after radical prostatectomy for localised prostate cancer: a cross-sectional survey

BACKGROUND

Localised prostate cancer affects patient's quality of life in many ways. The aim of this study was to explore factors related to self-rated health and life satisfaction for patients treated for prostate cancer, and to compare the results of these generic quality-of-life measures to the prostate cancer-specific quality-of-life measure (UCLA Prostate Cancer Index), which focuses on physical functioning.

MATERIAL AND METHODS

This cross-sectional survey was carried out among 183 men who underwent radical prostatectomy in 2012-2015 at a university hospital in Finland and were seen 1 year postsurgery. Approval from an ethics committee and written consents from participants were received. A questionnaire was used to evaluate patients' perceived quality of life. Logistic regression model, Spearman's correlation, Kruskal-Wallis test and Mann-Whitney U-test were used to analyse factors related to quality of life.

RESULTS

Of the 183 men in the study, 63% rated their health status as good, and 70% were satisfied with their lives after prostatectomy. Older age and better urinary function were the only factors that explained both better self-rated health and better satisfaction with life. The patients seemed not to interpret problems with sexual function as health-related problems. In our sample, sexual dysfunction was relatively severe, but patients considered them to be less harmful than urinary or bowel symptoms. Interestingly, 24% of the men with low sexual function did not find that dysfunction bothersome.

CONCLUSIONS

Objectively measured physical functioning is not necessarily in line with patients' experienced satisfaction with life and their self-ratings of health. More longitudinal and qualitative research is needed about the meanings that patients attach to physical treatment side effects and the extent to which they can adapt to them over time. With a bigger sample and longer follow-up time, it would be possible to identify men who particularly benefited from pretreatment counselling.
