Sexual Side Effects and Prostate Cancer Treatment Decisions: Patient Information Needs and Preferences

Perceptions of partial gland ablation for prostate cancer among men on active surveillance: A qualitative study

OBJECTIVES –

Partial gland ablation (PGA) therapy is an emerging treatment modality that targets specific areas of biopsy proven prostate cancer (PCa) to minimize treatment-related morbidity by sparing benign prostate. This qualitative study aims to explore and characterize perceptions and attitudes toward PGA in men with very-low-risk, low-risk, and favorable intermediate-risk PCa on active surveillance (AS).

DESIGN –

92 men diagnosed with very-low-risk, low-risk, and favorable intermediate-risk PCa on AS were invited to participate in semi-structured telephone interviews on PGA.

SETTING –

Single tertiary care center located in New York City.

PARTICIPANTS –

20 men with very-low-risk, low-risk, and favorable intermediate-risk PCa on AS participated in the interviews.

MAIN OUTCOME MEASURES –

Emerging themes on perceptions and attitudes toward PGA were developed from transcripts inductively coded and analyzed under standardized methodology.

RESULTS –

Four themes were derived from twenty interviews that represent the primary considerations in treatment decision-making: (1) the feeling of psychological safety associated with low-risk disease; (2) preference for minimally invasive treatments; (3) the central role of the physician; (4) and the pursuit of treatment options that align with disease severity. Eleven men (55%) expressed interest in pursuing PGA only if their cancer were to progress, while 9 men (45%) expressed interest at the current moment.

CONCLUSIONS –

Though an emerging treatment modality, patients were broadly accepting of PGA for PCa with men primarily debating the risks versus benefits of proactively treating low-risk disease. Additional research on men's preferences and attitudes toward PGA will further guide counseling and shared decision-making for PGA.

An ecological momentary assessment of self-management in prostate cancer survivors

PURPOSE

To assess the 'real-time' self-management strategies employed by prostate cancer survivors to inform personalised supportive care interventions in the future.

METHOD

A purposive sampling framework was used to recruit men with different stages of cancer and treatment to an ecological momentary assessment (capturing experiences in real time) study. Each participant was prompted by an audio alert to complete self-report questionnaires three times per day (93 data entries in total) for a total duration of 31 days. The personal digital assistant (PDA) and pocket interview software were used.

RESULTS

Prostate cancer survivors experienced a wide range of after-effects of therapy for which they used various self-management strategies. Many of the men experienced sexual dysfunction but did not perform any self-management.

CONCLUSION

Our findings reinforce the importance of having access to tailored, timely and person-centred supported self-management care plans. Real-time monitoring data can provide helpful information to facilitate tailored recommendations for self-management.

IMPLICATIONS FOR CANCER SURVIVORS

Prostate cancer survivors can experience unmet supportive care needs which may increase men's demands to perform self-management of their condition. Future clinical intervention studies aimed at utilising the remote exchange of real-time data serves to optimise tailored supported self-management.

New study suggests patients with advanced prostate cancer on androgen deprivation therapy need more dialogue with health care provider, especially around cardiovascular risk

PURPOSE

To study the current level of patients' awareness, and patient-health care provider (HCP) dialogue with respect to treatment-related risks, especially cardiovascular risk (CVR) associated with advanced prostate cancer (PCa) treatment.

METHODS

This 10-min online survey summarised data by treatment, region, and CVR (high or low).

RESULTS

Of the 411 patients, 83% were at high CVR while only 8% patients were aware of CVR associated with PCa treatment, majority of which (80%) were informed about this risk by HCPs. No significant difference in treatment approach was reported, regardless of patient's CVR status. Compared to other potential risks, patients were more likely to initiate discussion about heart problems with HCPs (38% patients). When prompted, 26% patients rated heart problems as the most concerning risk factor, and this concern was twice in patients with high CVR (28%) versus low CVR (14%). Lifestyle modifications were made by 64% patients, of which 45% patients reported an improvement in overall well-being. Improved diet was the most adopted lifestyle modification.

CONCLUSION

There is a need to enhance a constant patient-HCP dialogue, and both groups need to make a conscious effort in that direction. This would help in increasing patients' awareness of risks, having better treatment choice and acceptance, and reducing side-effects.

Lesbian, Gay, Bisexual, and Transgender (LGBT) Survivorship

OBJECTIVE

To discuss lesbian, gay, bisexual, and transgender (LGBT)-specific survivorship issues including: integrating sexual and gender minority identities with cancer survivor identities; coordinating medical care and disclosing identities to health care providers; dealing with late effects of treatment; and addressing LGBT family and relationship issues.

DATA SOURCES

Published articles, quotes from an online survey of 311 LGBT survivors.

CONCLUSION

The transition from active cancer treatment to survivorship presents challenges, and LGBT cancer survivors may face additional challenges as they enter the survivorship phase.

IMPLICATIONS FOR NURSING PRACTICE

Oncology nurses can improve the quality of survivorship care delivered to LGBT survivors and their caregivers by addressing the disparities and gaps in health care.

Omissions in Urology Residency Training Regarding Sexual Dysfunction Subsequent to Prostate Cancer Treatment: Identifying a Need

OBJECTIVE

To assess urology residents' current knowledge, practice, previous training, barriers, and training needs regarding prostate cancer treatment-related sexual dysfunction.

MATERIALS AND METHODS

A cross-sectional questionnaire study inventoried the practice patterns and training need of urology residents attending a national training course in June 2015.

RESULTS

Of 101 urology residents throughout the Netherlands, 87 attended the training (response rate 100%). Median age was 32 years (range 28-38); 55.2% were woman. Regardless of the residency level, most trainees had never received education about sexual dysfunction (58.6%), reported a limited level of knowledge (48.3%), and indicated an evident need for training (69.4%). The majority did not feel competent to advise prostate cancer patients regarding the treatment of sexual dysfunction (55.2%). Almost all participants inquired about preoperative erectile dysfunction (89.7%), and always informed about treatment-related sexual dysfunction (88.5%). At follow-up, 63.9% of the residents routinely addressed sexual complaints again. More than half of the participants indicated that urology residency training does not provide sufficient education on sexual dysfunction (54.8%).Time constraint (67.1%) and lack of training (35.3%) were the most frequently mentioned barriers.

CONCLUSION

Current urology residency does not pay sufficient attention to sexual communication skills and sexual dysfunction. The residents require more knowledge about and more practical training in sexual counseling. Findings support efforts to enhance the education of urology residents regarding prostate cancer treatment-related sexual dysfunction.

Treatment preference and patient centered prostate cancer care: Design and rationale

Prostate cancer is a slow progressing cancer that affects millions of men in the US. Due to uncertainties in outcomes and treatment complications, it is important that patients engage in informed decision making to choose the "optimal treatment". Patient centered care that encompasses informed decision-making can improve treatment choice and quality of care. Thus, assessing patient treatment preferences is critical for developing an effective decision support system. The objective of this patient-centered randomized clinical trial was to study the comparative effectiveness of a conjoint analysis intervention compared to usual care in improving subjective and objective outcomes in prostate cancer patients. We identified preferred attributes of alternative prostate cancer treatments that will aid in evaluating attributes of treatment options. In this two-phase study, in Phase 1 we used mixed methods to develop an adaptive conjoint task instrument. The conjoint task required the patients to trade-off attributes associated with treatments by assessing their relative importance. Phase 2 consisted of a randomized controlled trial of men with localized prostate cancer. We analyzed the effect of conjoint task intervention on the association between preferences, treatment and objective and subjective outcomes. Our conjoint task instrument can lead to a values-based patient-centered decision aid tool and help tailor treatment decision making to the values of prostate cancer patients. This will ultimately improve clinical decision making, clinical policy process, enhance patient centered care and improve prostate cancer outcomes.

Sexual dysfunction and infertility as late effects of cancer treatment

Sexual dysfunction is a common consequence of cancer treatment, affecting at least half of men and women treated for pelvic malignancies and over a quarter of people with other types of cancer. Problems are usually linked to damage to nerves, blood vessels, and hormones that underlie normal sexual function. Sexual dysfunction also may be associated with depression, anxiety, relationship conflict, and loss of self-esteem. Innovations in cancer treatment such as robotic surgery or more targeted radiation therapy have not had the anticipated result of reducing sexual dysfunction. Some new and effective cancer treatments, including aromatase inhibitors for breast cancer or chemoradiation for anal cancer also have very severe sexual morbidity. Cancer-related infertility is an issue for younger patients, who comprise a much smaller percentage of total cancer survivors. However, the long-term emotional impact of being unable to have a child after cancer can be extremely distressing. Advances in knowledge about how cancer treatments may damage fertility, as well as newer techniques to preserve fertility, offer hope to patients who have not completed their childbearing at cancer diagnosis. Unfortunately, surveys in industrialised nations confirm that many cancer patients are still not informed about potential changes to their sexual function or fertility, and all modalities of fertility preservation remain underutilised. After cancer treatment, many patients continue to have unmet needs for information about restoring sexual function or becoming a parent. Although more research is needed on optimal clinical practice, current studies suggest a multidisciplinary approach, including both medical and psychosocial treatment options.

Quality of Life and Sexual Health in the Aging of PCa Survivors

Prostate cancer (PCa) is the most common malignancy in elderly men. The progressive ageing of the world male population will further increase the need for tailored assessment and treatment of PCa patients. The determinant role of androgens and sexual hormones for PCa growth and progression has been established. However, several trials on androgens and PCa are recently focused on urinary continence, quality of life, and sexual function, suggesting a new point of view on the whole endocrinological aspect of PCa. During aging, metabolic syndrome, including diabetes, hypertension, dyslipidemia, and central obesity, can be associated with a chronic, low-grade inflammation of the prostate and with changes in the sex steroid pathways. These factors may affect both the carcinogenesis processes and treatment outcomes of PCa. Any treatment for PCa can have a long-lasting negative impact on quality of life and sexual health, which should be assessed by validated self-reported questionnaires. In particular, sexual health, urinary continence, and bowel function can be worsened after prostatectomy, radiotherapy, or hormone treatment, mostly in the elderly population. In the present review we summarized the current knowledge on the role of hormones, metabolic features, and primary treatments for PCa on the quality of life and sexual health of elderly Pca survivors.

Regulation of crosstalk between epithelial to mesenchymal transition molecules and MMP-9 mediates the antimetastatic activity of anethole in DU145 prostate cancer cells

The underlying antimetastatic mechanism of anethole (1) still remains unclear in association with the molecules of the epithelial to mesenchymal transition (EMT). Herein, the role of the EMT molecules was elucidated in terms of the antimetastatic activity of 1 using DU145 cells. Anethole significantly inhibited the adhesion of DU145 cells to vitronectin-coated plates, as well as migration in a wound-healing assay and invasion using a Boyden chamber. Also, anethole suppressed the expression of MMP-9 in DU145 cells by zymography, ELISA, and RT-PCR. Consistently, the silencing of MMP-9 enhanced the activity of 1 to upregulate the expression of E-cadherin and to attenuate the expression of Vimentin in DU145 cells. Compound 1 enhanced E-cadherin, which is an epithelial marker and attenuated the expression of Vimentin, Twist, and Snail as mesenchymal molecules at the mRNA level. Consistently, anethole upregulated E-cadherin and downregulated the expression of Vimentin, Twist and PI3K, and AKT at the protein level in DU145 cells. Conversely, the antimetastatic effects of 1 to inhibit invasion and the expression of MMP-9 and upregulate E-cadherin were reversed by the EMT inducer TGF-β in DU145 cells. Overall, the present findings suggest that anethole exerts antimetastatic activity via regulation of crosstalk between EMT molecules and MMP-9 on the basis of the in vitro data obtained.

Patient preoperative expectations of urinary, bowel, hormonal and sexual functioning do not match actual outcomes 1 year after radical prostatectomy

PURPOSE

We studied patient expectations of post-prostatectomy recovery from urinary incontinence, and urinary irritable, hormonal, bowel and sexual function symptoms after preoperative counseling.

MATERIALS AND METHODS

Patients undergoing radical prostatectomy, recruited between June 2007 and November 2008, were extensively counseled preoperatively regarding expected outcomes. They were assessed at baseline and 1 year after surgery using the short form of the Expanded Prostate Index Composite. Their baseline expectations of functional outcomes 1 year after surgery were assessed using the Expanded Prostate Index Composite-Expectations. Pearson's correlation coefficient and a multiple linear regression were used to assess the associations between Expanded Prostate Index Composite-Expectations and Expanded Prostate Index Composite-Short Form at baseline and 1 year.

RESULTS

A total of 152 consenting patients completed all questionnaires. Baseline sexual function score predicted significantly expectations of sexual function (p<0.0001) and urinary incontinence (p<0.0001) scores. Expanded Prostate Index Composite-Expectations predicted Expanded Prostate Index Composite-sexual function at 1 year (p<0.0001). Of the patients 36% and 40% expected the same as baseline function at 1 year in urinary incontinence and sexual function, respectively, and 17%, 45%, 39%, 15% and 32% expected worse than baseline function at 1 year in urinary incontinence, urinary irritable symptoms, bowel function, hormonal function and sexual function, respectively. One year after prostatectomy fewer than 22% of patients attained lower than expected urinary irritable symptoms, and bowel and hormonal function. However, 47% and 44% of patients attained lower than expected function for urinary incontinence and sexual function, respectively. Surprisingly 12% and 17% of patients expected better than baseline urinary incontinence and sexual function at 1 year after surgery.

CONCLUSIONS

Men have unrealistic expectations of urinary and sexual function after prostatectomy despite preoperative counseling. We hypothesize potentially responsible psychological mechanisms. These data provide a baseline for further preoperative educational interventions.

Coping with sexual concerns after cancer: the use of flexible coping

INTRODUCTION

Although cancer treatment commonly has a negative impact on sexual functioning, sexual concerns are still largely undertreated in routine cancer care. The medical model that guides current approaches to sexual care in cancer does not adequately address key patient needs.

METHODS

In this paper, we describe a broader approach to understanding and treating sexual concerns in cancer that focuses on the construct of flexibility in behavioral and cognitive coping strategies. We previously presented this model in the context of general medical conditions. We now adapt this model to the context of cancer, focusing on issues related to the benefits of flexible coping, interventions that shift perspectives following cancer, and on coping as a couple.

RESULTS

We argue that coping flexibly with sexual concerns is likely to lead to improvements in mood and sexual and relationship satisfaction. We present clinical applications of the flexible coping model, including suggestions for assessment and sexual concerns and methods of introducing flexible coping into both the content and process of clinical interactions with patients.

DISCUSSION

Finally, we discuss areas for future research, including the development of a validated instrument, the use of electronic methods of assessment, and intervention trials directly addressing flexibility in coping.
