RESUMO

This study describes sources of support utilised by men with localised prostate cancer in the first year after diagnosis and examines characteristics associated with help-seeking for men with unmet needs. A cross-sectional survey of 331 patients from a population-based sample who were in the first year after diagnosis (M = 9.6, SD = 1.9) was conducted to assess sources of support, unmet supportive care needs, domain-specific quality of life and psychological distress. Overall, 82% of men reported unmet supportive care needs. The top five needs were sexuality (58%); prostate cancer-specific (57%); psychological (47%); physical and daily living (41%); and health system and information (31%). Professional support was most often sought from doctors (51%). Across most domains, men who were older (Ps ≤ 0.03), less well educated (Ps ≤ 0.04) and more depressed (Ps ≤ 0.05) were less likely to seek help for unmet needs. Greater sexual help-seeking was related to better sexual function (P = 0.03), higher education (P ≤ 0.03) and less depression (P = 0.05). Unmet supportive care needs are highly prevalent after localised prostate cancer diagnosis with older age, lower education and higher depression apparent barriers to help-seeking. Interventions that link across medicine, nursing and community based peer support may be an accessible approach to meeting these needs.

RESUMO

The purpose of this study was to understand the extent, nature and variability of the current economic burden of prostate cancer among Australian men. An online cross-sectional survey was developed that combined pre-existing economic measures and new questions. With few exceptions, the online survey was viable and acceptable to participants. The main outcomes were self-reported out-of-pocket costs of prostate cancer diagnosis and treatment, changes in employment status and household finances. Men were recruited from prostate cancer support groups throughout Australia. Descriptive statistical analyses were undertaken. A total of 289 men responded to the survey during April and June 2013. Our study found that men recently diagnosed (within 16 months of the survey) (n = 65) reported spending a median AU$8000 (interquartile range AU$14 000) for their cancer treatment while 75% of men spent up to AU$17 000 (2012). Twenty per cent of all men found the cost of treating their prostate cancer caused them 'a great deal' of distress. The findings suggest a large variability in medical costs for prostate cancer treatment with 5% of men spending $250 or less in out-of-pocket expenses and some men facing very high costs. On average, respondents in paid employment at diagnosis stated that they had retired 4-5 years earlier than planned.

RESUMO

We present a systematic review providing estimates of the overall and regional burden of infectious complications following prostate biopsy. A directly standardized prevalence estimate was used because it reflects the burden of disease more explicitly. Complications included sepsis, hospitalization, bacteraemia, bacteriuria, and acute urinary retention after biopsy. There were 165 articles, comprising 162 577 patients, included in the final analysis. Our findings demonstrate that transrectal biopsy was associated with a higher burden of hospitalization (1·1% vs. 0·9%) and sepsis (0·8% vs. 0·1%) compared to transperineal biopsy, while acute urinary retention was more prevalent after transperineal than transrectal biopsy (4·2% vs. 0·9%). The differences were statistically non-significant because of large heterogeneity across countries. We also demonstrate and discuss regional variations in complication rates, with Asian studies reporting higher rates of sepsis and hospitalization.

RESUMO

OBJECTIVE: To examine prevalence and predictors of cancer-specific distress in undiagnosed men with and without a family history of prostate cancer, and to examine the contribution of perceptions of an affected relative's cancer experience on the distress of unaffected male relatives. METHODS: Men with a first degree relative with prostate cancer (n = 207) and men without a family history (n = 239) from Australia completed a Computer Assisted Telephone Interview. Participants completed the Prostate Cancer Anxiety Subscale of the Memorial Anxiety Scale for Prostate Cancer, measures of perceived risk, and socio-demographic information. Men with a family history provided details about their family history (number of relatives diagnosed with and dead from prostate cancer, relationship to affected relative, months since diagnosis) and reported their perceptions of their affected relative's prostate cancer experience including perceptions of threat related to the relative's diagnosis and perceived treatment phase and prognosis. RESULTS: Cancer-specific distress was low for all men and there was no significant difference in the distress experienced by men with and without a family history. Regression analyses showed that for all men, cancer-specific distress increased with urinary symptoms and decreased in those with higher education and in older participants. For men with a family history, having a relative who died from prostate cancer and perceiving greater threat from a relative's diagnosis was associated with greater cancer-specific distress. CONCLUSIONS: Interventions would benefit from examining appraisals of familial risk and examining prospective assessments of distress in the unaffected male relatives of men with prostate cancer over the course of the cancer trajectory.

RESUMO

BACKGROUND: The present study assessed the feasibility of delivering peer support for couples coping with prostate cancer within a trial design. METHODS/DESIGN: Ten peer volunteers completed training in research protocols and delivering tele-based couples support to men with prostate cancer and their partners. Twenty couples received an eight session intervention and were assessed before surgery and 3 and 6 months subsequently for adjustment outcomes. A focus group investigated the peers' experiences. RESULTS: Peers were motivated by altruism, a belief in research, and reported personal growth. The research protocol at times conflicted with lay models of helping, and the focus on sexuality and couples was challenging. Distress decreased over time but more so for partners; unmet sexuality needs did not improve. CONCLUSION: Peer support appears promising as a model to support couples facing prostate cancer.

RESUMO

BACKGROUND: Prostate cancer is the most common cancer in men in the Western world with well-described negative effects from treatments. However, outcomes are highly heterogeneous. A Phase 3 trial of a psycho-educational intervention was undertaken, aiming to reduce cancer-specific and decision-related distress and improve quality of life for men newly diagnosed with localised prostate cancer. METHODS: Seven hundred forty (81.7%) men were recruited after diagnosis and before treatment and randomised to a tele-based nurse-delivered five-session psycho-educational intervention (N = 372) or usual care (N = 368). Participants were assessed before treatment and 2, 6, 12 and 24 months post-treatment. Outcome measures included cancer-specific and decision-related distress, cognitive judgmental adjustment, subjective well-being, and domain-specific and health-related quality of life. Social support was assessed as a potential moderator. RESULTS: No unconditioned effects were found. Classification analyses on pre-randomisation measures distinguished three subgroups: younger, higher education and income men (N = 90); younger, lower education and income men (N = 106); and older men (N = 344). Younger, higher education and income men showed positive intervention effects for cancer-specific distress (p = 0.008) and mental health (p = 0.042). By contrast, for younger, lower education men, participation in the intervention was associated with decreases in cognitive judgmental adjustment over time (p = 0.006). CONCLUSIONS: Response to intervention and adjustment over time varied according to previous sexual functioning, age, educational level and income. How to best intervene with younger, low education, low income men with prostate cancer is a critical future research question.

RESUMO

Prostate cancer (PrCa) is the most frequently diagnosed male cancer in developed countries. We conducted a multi-stage genome-wide association study for PrCa and previously reported the results of the first two stages, which identified 16 PrCa susceptibility loci. We report here the results of stage 3, in which we evaluated 1,536 SNPs in 4,574 individuals with prostate cancer (cases) and 4,164 controls. We followed up ten new association signals through genotyping in 51,311 samples in 30 studies from the Prostate Cancer Association Group to Investigate Cancer Associated Alterations in the Genome (PRACTICAL) consortium. In addition to replicating previously reported loci, we identified seven new prostate cancer susceptibility loci on chromosomes 2p11, 3q23, 3q26, 5p12, 6p21, 12q13 and Xq12 (P = 4.0 × 10(-8) to P = 2.7 × 10(-24)). We also identified a SNP in TERT more strongly associated with PrCa than that previously reported. More than 40 PrCa susceptibility loci, explaining ∼25% of the familial risk in this disease, have now been identified.

RESUMO

First-degree relatives of men with prostate cancer have a higher risk of being diagnosed with prostate cancer than men without a family history. The present review examines the prevalence and predictors of testing in first-degree relatives, perceptions of risk, prostate cancer knowledge and psychological consequences of screening. Medline, PsycInfo and Cinahl databases were searched for articles examining risk perceptions or screening practices of first-degree relatives of men with prostate cancer for the period of 1990 to August 2007. Eighteen studies were eligible for inclusion. First-degree relatives participated in prostate-specific antigen (PSA) testing more and perceived their risk of prostate cancer to be higher than men without a family history. Family history factors (e.g. being an unaffected son rather than an unaffected brother) were consistent predictors of PSA testing. Studies were characterized by sampling biases and a lack of longitudinal assessments. Prospective, longitudinal assessments with well-validated and comprehensive measures are needed to identify factors that cue the uptake of screening and from this develop an evidence base for decision support. Men with a family history may benefit from targeted communication about the risks and benefits of prostate cancer testing that responds to the implications of their heightened risk.

RESUMO

A recent genome-wide association study found that genetic variants on chromosomes 3, 6, 7, 10, 11, 19 and X were associated with prostate cancer risk. We evaluated the most significant single-nucleotide polymorphisms (SNP) in these loci using a worldwide consortium of 13 groups (PRACTICAL). Blood DNA from 7,370 prostate cancer cases and 5,742 male controls was analyzed by genotyping assays. Odds ratios (OR) associated with each genotype were estimated using unconditional logistic regression. Six of the seven SNPs showed clear evidence of association with prostate cancer (P = 0.0007-P = 10(-17)). For each of these six SNPs, the estimated per-allele OR was similar to those previously reported and ranged from 1.12 to 1.29. One SNP on 3p12 (rs2660753) showed a weaker association than previously reported [per-allele OR, 1.08 (95% confidence interval, 1.00-1.16; P = 0.06) versus 1.18 (95% confidence interval, 1.06-1.31)]. The combined risks associated with each pair of SNPs were consistent with a multiplicative risk model. Under this model, and in combination with previously reported SNPs on 8q and 17q, these loci explain 16% of the familial risk of the disease, and men in the top 10% of the risk distribution have a 2.1-fold increased risk relative to general population rates. This study provides strong confirmation of these susceptibility loci in multiple populations and shows that they make an important contribution to prostate cancer risk prediction.

RESUMO

BACKGROUND: Prostate cancer is the most common male cancer in the Western world. The most substantial long term morbidity from this cancer is sexual dysfunction with consequent adverse changes in couple and intimate relationships. Research to date has not identified an effective way to improve sexual and psychosocial adjustment for both men with prostate cancer and their partners. As well, the efficacy and cost effectiveness of peer counselling as opposed to professional models of service delivery has not yet been empirically tested. This paper presents the design of a three arm randomised controlled trial (peer vs. nurse counselling vs. usual care) that will evaluate the efficacy of two couples-based sexuality interventions (ProsCan for Couples: Peer support vs. nurse counselling) on men's and women's sexual and psychosocial adjustment after surgical treatment for localised prostate cancer; in addition to cost-effectiveness. METHODS/DESIGN: Seventy couples per condition (210 couples in total) will be recruited after diagnosis and before treatment through urology private practices and hospital outpatient clinics and randomised to (1) usual care; (2) eight sessions of peer-delivered telephone support with DVD education; and (3) eight sessions of oncology nurse-delivered telephone counselling with DVD education. Two intervention sessions will be delivered before surgery and six over the six months post-surgery. The intervention will utilise a cognitive behavioural approach along with couple relationship education focussed on relationship enhancement and helping the couple to conjointly manage the stresses of cancer diagnosis and treatment. Participants will be assessed at baseline (before surgery) and 3, 6 and 12 months post-surgery. Outcome measures include: sexual adjustment; unmet sexuality supportive care needs; attitudes to sexual help seeking; psychological adjustment; benefit finding and quality of life. DISCUSSION: The study will provide recommendations about the efficacy of peer support vs. nurse counselling to facilitate better sexual and couple adjustment after prostate cancer as well as recommendations on whether the interventions represent efficient health service delivery.

RESUMO

BACKGROUND: Prostate cancer is the most common male cancer in the Western world but is highly heterogeneous in disease progression and outcomes. Consequently, the most substantial morbidity may actually arise from the adverse psychosocial impact of distress in decision-making and long term quality of life effects such as impotence. This paper presents the design of a randomised controlled trial of a decision support/psychosocial intervention for men newly diagnosed with localised prostate cancer. METHODS/DESIGN: 350 men per condition (700 men in total) have been recruited after diagnosis and before treatment through urology private practices and hospital outpatient clinics and randomised to 1) a tele-based nurse delivered five session decision support/psychosocial intervention or 2) a usual care control group. Two intervention sessions are delivered before treatment that address decision support, stress management and preparation for treatment. Three further sessions are provided three weeks, seven weeks and five months after treatment that focus on adjustment to cancer, problem solving and coping with treatment side effects. Participants are assessed at baseline (before treatment) and 2, 6, 12, 24 and 36 months post-treatment. Outcome measures include: cancer threat appraisal; decision-related distress and bother from treatment side effects; involvement in decision making; satisfaction with health care; heath care utilisation; use of health care resources; and a return to previous activities. DISCUSSION: The study will provide recommendations about the efficacy of early decision support to facilitate adjustment after prostate cancer. As well the study will identify men diagnosed with localised prostate cancer at risk of poorer long term psychosocial adjustment. TRIAL REGISTRATION: ACTRN012607000233426.

RESUMO

In the quest for markers of expression and progression for prostate cancer (PCa), the majority of studies have focussed on molecular data exclusively from primary tumours. Although expression in metastases is inferred, a lack of correlation with secondary tumours potentially limits their applicability diagnostically and therapeutically. Molecular targets were identified by examining expression profiles of prostate cell lines using cDNA microarrays. Those genes identified were verified on PCa cell lines and tumour samples from both primary and secondary tumours using real-time RT-PCR, western blotting and immunohistochemistry. Claudin-4, coding for an integral membrane cell-junction protein, was the most significantly (P<0.00001) upregulated marker in both primary and metastatic tumour specimens compared with benign prostatic hyperplasia at both RNA and protein levels. In primary tumours, claudin-4 was more highly expressed in lower grade (Gleason 6) lesions than in higher grade (Gleason >or=7) cancers. Expression was prominent throughout metastases from a variety of secondary sites in fresh-frozen and formalin-fixed specimens from both androgen-intact and androgen-suppressed patients. As a result of its prominent expression in both primary and secondary PCas, together with its established role as a receptor for Clostridium perfringens enterotoxin, claudin-4 may be useful as a potential marker and therapeutic target for PCa metastases.

RESUMO

GOAL: Men diagnosed with prostate cancer experience high decision-related distress concurrent with cancer-related distress. Psycho-education, problem solving and decision support were integrated in a novel telephone-delivered supportive care intervention targeting men at diagnosis and assessed for feasibility. MATERIALS AND METHODS: An exploratory single-group pre-post-test design tracked session frequency, duration and content. Standardised measures assessed decisional conflict, cancer-related distress and decision involvement. Brief screening measures for psychological and decision-related distress were incorporated into the intervention protocol. Twenty men (77% response) newly diagnosed with localised prostate cancer received the intervention. RESULTS: Men who were undecided about treatment at study entry required more pre-treatment intervention calls (p < 0.013). Pre-treatment support calls were longer (M = 40.2 min) and more complex by comparison to post-treatment calls (M = 30.9 min; p < 0.002). Brief screening for decision-related distress correlated with concurrent (p < 0.008) and prospective (p < 0.046) decisional conflict. Decisional conflict and intrusion decreased at post-test (p < 0.001; p < 0.005). Men reported a high level of satisfaction with the support received with benefits identified including anonymity and accessibility. CONCLUSIONS: In this setting, a tele-based supportive care and decision support intervention for men newly diagnosed with prostate cancer was feasible. The use of brief screening measures as within-intervention clinical tools appears promising.

RESUMO

The prostate-specific antigen-related serine protease gene, kallikrein 4 (KLK4), is expressed in the prostate and, more importantly, overexpressed in prostate cancer. Several KLK4 mRNA splice variants have been reported, but it is still not clear which of these is most relevant to prostate cancer. Here we report that, in addition to the full-length KLK4 (KLK4-254) transcript, the exon 1 deleted KLK4 transcripts, in particular, the 5'-truncated KLK4-205 transcript, is expressed in prostate cancer. Using V5/His6 and green fluorescent protein (GFP) carboxy terminal tagged expression constructs and immunocytochemical approaches, we found that hK4-254 is cytoplasmically localized, while the N-terminal truncated hK4-205 is in the nucleus of transfected PC-3 prostate cancer cells. At the protein level, using anti-hK4 peptide antibodies specific to different regions of hK4-254 (N-terminal and C-terminal), we also demonstrated that endogenous hK4-254 (detected with the N-terminal antibody) is more intensely stained in malignant cells than in benign prostate cells, and is secreted into seminal fluid. In contrast, for the endogenous nuclear-localized N-terminal truncated hK4-205 form, there was less difference in staining intensity between benign and cancer glands. Thus, KLK4-254/hK4-254 may have utility as an immunohistochemical marker for prostate cancer. Our studies also indicate that the expression levels of the truncated KLK4 transcripts, but not KLK4-254, are regulated by androgens in LNCaP cells. Thus, these data demonstrate that there are two major isoforms of hK4 (KLK4-254/hK4-254 and KLK4-205/hK4-205) expressed in prostate cancer with different regulatory and expression profiles that imply both secreted and novel nuclear roles.

RESUMO

OBJECTIVE: To develop and test a measure for assessing peer support for men attending prostate cancer support groups, and to describe socio-demographic, medical and adjustment characteristics of Australian men who attend these support groups. PATIENTS AND METHODS: In all, 1224 men (51% response) from 44 prostate-cancer support groups across Australia were recruited by mail. Men completed self-report measures that included the Prostate Cancer Peer Support Inventory (PCSI), the UCLA Prostate Cancer Index bother scales, psychological distress, quality of life (QoL), bother from pain and tiredness, perception of the clinician's support for group participation. Group-level variables were also included in the analyses. RESULTS: Peer support was rated positively by most men; a high satisfaction with support groups was related to better QoL, lower pain, younger age, higher perceived clinician support for group participation, use of alternative therapies, lower education, and regular attendance; dissatisfaction with support groups was related to higher psychological distress, lower QoL, and lower perceived clinician support for group participation. Group variables did not predict positive or negative support. Overall QoL was similar to community norms and psychological distress was low, with only 8% of men reporting high distress. The most common physical symptom was sexual bother, with 74% of men reporting moderate or high bother. CONCLUSIONS: The PCSI was a useful measure of peer support. Perception of the benefits of peer support was related to individual but not group differences. The clinicians' attitudes to participation in support groups influenced the men's experience of these groups, and this finding has implications for developing support services for these men.

RESUMO

Although the use of alternative therapies is highly prevalent amongst men with prostate cancer, research about the predictors of such use is limited. The current study aimed to describe prospectively the use of alternative therapies by men diagnosed with localized prostate cancer and identify predictors of alternative therapy use. In all, 111 men newly diagnosed with localized prostate cancer (93% response) were recruited to the study prior to treatment. Men's use of alternative therapies and psychological variables including: psychological distress, orientation to health care, decisional conflict, and health locus of control, were assessed at three time points-(1) before treatment; (2) 2 months after completion of treatment; and (3) 12 months after completion of treatment. Demographic information was also obtained. The percentage of men using alternative therapies was 25, 17 and 14% before treatment, 2 and 12 months after treatment, respectively. In general, the most commonly used therapies were dietary changes, vitamins and herbal and nutrient remedies. Alternative therapy use was not related to final treatment choices. Before treatment, men who used alternative therapies were more uncertain about prostate cancer compared to men who were not using these therapies. Men who were using alternative therapies 12 months after treatment were less psychologically distressed that men who were not using these therapies. Health locus of control and orientation to health care were not found to be related to men's use of alternative therapies. In conclusion, men's use of alternative therapies after localized prostate cancer varied across time in terms of the incidence of use, the types of therapies used, and the psychological correlates of therapy use. Informational support that targets uncertainty about prostate cancer may assist men at diagnosis who are considering alternative therapy use.

RESUMO

OBJECTIVES: To investigate the effects of different management strategies for non-localized prostate cancer on men's quality of life and cognitive functioning. PATIENTS, SUBJECTS AND METHODS: Men with prostate cancer were randomly assigned to one of four treatment arms: leuprorelin, goserelin, cyproterone acetate (CPA), or close clinical monitoring. In a repeated-measures design, men were assessed before treatment (baseline) and after 6 and 12 months of treatment. A community comparison group of men of the same age with no prostate cancer participated for the same length of time. The men were recruited from public and private urology departments from university teaching hospitals. All those with prostate cancer who were eligible for hormonal therapy had no symptoms requiring immediate therapy. In all, 82 patients were randomized and 62 completed the 1-year study, and of the 20 community participants, 15 completed the study. The main outcome measures were obtained from questionnaires on emotional distress, existential satisfaction, physical function and symptoms, social and role function, subjective cognitive function, and sexual function, combined with standard neuropsychological tests of memory, attention, and executive functions. RESULTS: Sexual dysfunction increased for patients on androgen-suppressing therapies, and emotional distress increased in those assigned to CPA or close clinical monitoring. Compared with before treatment there was evidence of an adverse effect of leuprorelin, goserelin, and CPA on cognitive function. CONCLUSIONS: In deciding the timing of androgen suppression therapy for prostate cancer, consideration should be given to potential adverse effects on quality of life and cognitive function.
