The sex gap in bladder cancer survival - a missing link in bladder cancer care?

The differences in bladder cancer outcomes between the sexes has again been highlighted. Uncommon among cancers, bladder cancer outcomes are notably worse for women than for men. Furthermore, bladder cancer is three to four times more common among men than among women. Factors that might explain these sex differences include understanding the importance of haematuria as a symptom of bladder cancer by both clinicians and patients, the resultant delays in diagnosis and referral of women with haematuria, and health-care access. Notably, these factors seem to have geographical variation and are not consistent across all health-care systems. Likewise, data relating to sex-specific treatment responses for patients with non-muscle-invasive or muscle-invasive bladder cancer are inconsistent. The influence of differences in the microbiome, bladder wall thickness and urine dwell times remain to be elucidated. The interplay of hormone signalling, gene expression, immunology and the tumour microenvironment remains complex but probably underpins the sexual dimorphism in disease incidence and stage and histology at presentation. The contribution of these biological phenomena to sex-specific outcome differences is probable, albeit potentially treatment-specific, and further understanding is required. Notwithstanding these aspects, we identify opportunities to harness biological differences to improve treatment outcomes, as well as areas of fundamental and translational research to pursue. At the level of policy and health-care delivery, improvements can be made across the domains of patient awareness, clinician education, referral pathways and guideline-based care. Together, we aim to highlight opportunities to close the sex gap in bladder cancer outcomes.

A Repurposing Programme Evaluating Transdermal Oestradiol Patches for the Treatment of Prostate Cancer Within the PATCH and STAMPEDE Trials: Current Results and Adapting Trial Design

AIMS

Androgen deprivation therapy (ADT), usually achieved with luteinising hormone releasing hormone analogues (LHRHa), is central to prostate cancer management. LHRHa reduce both testosterone and oestrogen and are associated with significant long-term toxicity. Previous use of oral oestrogens as ADT was curtailed because of cardiovascular toxicity. Transdermal oestrogen (tE2) patches are a potential alternative ADT, supressing testosterone without the associated oestrogen-depletion toxicities (osteoporosis, hot flushes, metabolic abnormalities) and avoiding cardiovascular toxicity, and we here describe their evaluation in men with prostate cancer.

MATERIALS AND METHODS

The PATCH (NCT00303784) adaptive trials programme (incorporating recruitment through the STAMPEDE [NCT00268476] platform) is evaluating the safety and efficacy of tE2 patches as ADT for men with prostate cancer. An initial randomised (LHRHa versus tE2) phase II study (n = 251) with cardiovascular toxicity as the primary outcome measure has expanded into a phase III evaluation. Those with locally advanced (M0) or metastatic (M1) prostate cancer are eligible. To reflect changes in both management and prognosis, the PATCH programme is now evaluating these cohorts separately.

RESULTS

Recruitment is complete, with 1362 and 1128 in the M0 and M1 cohorts, respectively. Rates of androgen suppression with tE2 were equivalent to LHRHa, with improved metabolic parameters, quality of life and bone health indices (mean absolute change in lumbar spine bone mineral density of -3.0% for LHRHa and +7.9% for tE2 with an estimated difference between arms of 9.3% (95% confidence interval 5.3-13.4). Importantly, rates of cardiovascular events were not significantly different between the two arms and the time to first cardiovascular event did not differ between treatment groups (hazard ratio 1.11, 95% confidence interval 0.80-1.53; P = 0.54). Oncological outcomes are awaited.

FUTURE

Efficacy results for the M0 cohort (primary outcome measure metastases-free survival) are expected in the final quarter of 2023. For M1 patients (primary outcome measure - overall survival), analysis using restricted mean survival time is being explored. Allied translational work on longitudinal samples is underway.

Fifteen-Year Outcomes after Monitoring, Surgery, or Radiotherapy for Prostate Cancer

BACKGROUND

Between 1999 and 2009 in the United Kingdom, 82,429 men between 50 and 69 years of age received a prostate-specific antigen (PSA) test. Localized prostate cancer was diagnosed in 2664 men. Of these men, 1643 were enrolled in a trial to evaluate the effectiveness of treatments, with 545 randomly assigned to receive active monitoring, 553 to undergo prostatectomy, and 545 to undergo radiotherapy.

METHODS

At a median follow-up of 15 years (range, 11 to 21), we compared the results in this population with respect to death from prostate cancer (the primary outcome) and death from any cause, metastases, disease progression, and initiation of long-term androgen-deprivation therapy (secondary outcomes).

RESULTS

Follow-up was complete for 1610 patients (98%). A risk-stratification analysis showed that more than one third of the men had intermediate or high-risk disease at diagnosis. Death from prostate cancer occurred in 45 men (2.7%): 17 (3.1%) in the active-monitoring group, 12 (2.2%) in the prostatectomy group, and 16 (2.9%) in the radiotherapy group (P = 0.53 for the overall comparison). Death from any cause occurred in 356 men (21.7%), with similar numbers in all three groups. Metastases developed in 51 men (9.4%) in the active-monitoring group, in 26 (4.7%) in the prostatectomy group, and in 27 (5.0%) in the radiotherapy group. Long-term androgen-deprivation therapy was initiated in 69 men (12.7%), 40 (7.2%), and 42 (7.7%), respectively; clinical progression occurred in 141 men (25.9%), 58 (10.5%), and 60 (11.0%), respectively. In the active-monitoring group, 133 men (24.4%) were alive without any prostate cancer treatment at the end of follow-up. No differential effects on cancer-specific mortality were noted in relation to the baseline PSA level, tumor stage or grade, or risk-stratification score. No treatment complications were reported after the 10-year analysis.

CONCLUSIONS

After 15 years of follow-up, prostate cancer-specific mortality was low regardless of the treatment assigned. Thus, the choice of therapy involves weighing trade-offs between benefits and harms associated with treatments for localized prostate cancer.

Patient-Reported Outcomes 12 Years after Localized Prostate Cancer Treatment

Outcomes after Localized Prostate Cancer TreatmentDonovan et al. present the long-term patient-reported outcomes of 1643 randomly assigned participants in the ProtecT (Prostate Testing for Cancer and Treatment) trial. Functional and quality-of-life impacts of prostatectomy, radiotherapy with neoadjuvant androgen deprivation, and active monitoring are described. Over the trial period from 7 to 12 years, generic quality-of-life scores were similar among all groups, with varying degrees of impact on urinary leakage, sexual function, and fecal leakage depending on the treatment group.

Healthcare systems data in the context of clinical trials - A comparison of cardiovascular data from a clinical trial dataset with routinely collected data

BACKGROUND

Routinely-collected healthcare systems data (HSD) are proposed to improve the efficiency of clinical trials. A comparison was undertaken between cardiovascular (CVS) data from a clinical trial database with two HSD resources.

METHODS

Protocol-defined and clinically reviewed CVS events (heart failure (HF), acute coronary syndrome (ACS), thromboembolic stroke, venous and arterial thromboembolism) were identified within the trial data. Data (using pre-specified codes) was obtained from NHS Hospital Episode Statistics (HES) and National Institute for Cardiovascular Outcomes Research (NICOR) HF and myocardial ischaemia audits for trial participants recruited in England between 2010 and 2018 who had provided consent. The primary comparison was trial data versus HES inpatient (APC) main diagnosis (Box-1). Correlations are presented with descriptive statistics and Venn diagrams. Reasons for non-correlation were explored.

RESULTS

From 1200 eligible participants, 71 protocol-defined clinically reviewed CVS events were recorded in the trial database. 45 resulted in a hospital admission and therefore could have been recorded by either HES APC/ NICOR. Of these, 27/45 (60%) were recorded by HES inpatient (Box-1) with an additional 30 potential events also identified. HF and ACS were potentially recorded in all 3 datasets; trial data recorded 18, HES APC 29 and NICOR 24 events respectively. 12/18 (67%) of the HF/ACS events in the trial dataset were recorded by NICOR.

CONCLUSION

Concordance between datasets was lower than anticipated and the HSD used could not straightforwardly replace current trial practices, nor directly identify protocol-defined CVS events. Further work is required to improve the quality of HSD and consider event definitions when designing clinical trials incorporating HSD.

Transdermal oestradiol for androgen suppression in prostate cancer: long-term cardiovascular outcomes from the randomised Prostate Adenocarcinoma Transcutaneous Hormone (PATCH) trial programme

BACKGROUND

Androgen suppression is a central component of prostate cancer management but causes substantial long-term toxicity. Transdermal administration of oestradiol (tE2) circumvents first-pass hepatic metabolism and, therefore, should avoid the cardiovascular toxicity seen with oral oestrogen and the oestrogen-depletion effects seen with luteinising hormone releasing hormone agonists (LHRHa). We present long-term cardiovascular follow-up data from the Prostate Adenocarcinoma Transcutaneous Hormone (PATCH) trial programme.

METHODS

PATCH is a seamless phase 2/3, randomised, multicentre trial programme at 52 study sites in the UK. Men with locally advanced or metastatic prostate cancer were randomly allocated (1:2 from August, 2007 then 1:1 from February, 2011) to either LHRHa according to local practice or tE2 patches (four 100 μg patches per 24 h, changed twice weekly, reducing to three patches twice weekly if castrate at 4 weeks [defined as testosterone ≤1·7 nmol/L]). Randomisation was done using a computer-based minimisation algorithm and was stratified by several factors, including disease stage, age, smoking status, and family history of cardiac disease. The primary outcome of this analysis was cardiovascular morbidity and mortality. Cardiovascular events, including heart failure, acute coronary syndrome, thromboembolic stroke, and other thromboembolic events, were confirmed using predefined criteria and source data. Sudden or unexpected deaths were attributed to a cardiovascular category if a confirmatory post-mortem report was available and as other relevant events if no post-mortem report was available. PATCH is registered with the ISRCTN registry, ISRCTN70406718; the study is ongoing and adaptive.

FINDINGS

Between Aug 14, 2007, and July 30, 2019, 1694 men were randomly allocated either LHRHa (n=790) or tE2 patches (n=904). Overall, median follow-up was 3·9 (IQR 2·4-7·0) years. Respective castration rates at 1 month and 3 months were 65% and 93% among patients assigned LHRHa and 83% and 93% among those allocated tE2. 157 events from 145 men met predefined cardiovascular criteria, with a further ten sudden deaths with no post-mortem report (total 167 events in 153 men). 26 (2%) of 1694 patients had fatal cardiovascular events, 15 (2%) of 790 assigned LHRHa and 11 (1%) of 904 allocated tE2. The time to first cardiovascular event did not differ between treatments (hazard ratio 1·11, 95% CI 0·80-1·53; p=0·54 [including sudden deaths without post-mortem report]; 1·20, 0·86-1·68; p=0·29 [confirmed group only]). 30 (34%) of 89 cardiovascular events in patients assigned tE2 occurred more than 3 months after tE2 was stopped or changed to LHRHa. The most frequent adverse events were gynaecomastia (all grades), with 279 (38%) events in 730 patients who received LHRHa versus 690 (86%) in 807 patients who received tE2 (p<0·0001) and hot flushes (all grades) in 628 (86%) of those who received LHRHa versus 280 (35%) who received tE2 (p<0·0001).

INTERPRETATION

Long-term data comparing tE2 patches with LHRHa show no evidence of a difference between treatments in cardiovascular mortality or morbidity. Oestrogens administered transdermally should be reconsidered for androgen suppression in the management of prostate cancer.

Strategies adopted by men to deal with uncertainty and anxiety when following an active surveillance/monitoring protocol for localised prostate cancer and implications for care: a longitudinal qualitative study embedded within the ProtecT trial

OBJECTIVES

Active surveillance (AS) enables men with low risk, localised prostate cancer (PCa) to avoid radical treatment unless progression occurs; lack of reliable AS protocols to determine progression leaves uncertainties for men and clinicians. This study investigated men's strategies for coping with the uncertainties of active monitoring (AM, a surveillance strategy within the Prostate testing for cancer and Treatment, ProtecT trial) over the longer term and implications for optimising supportive care.

DESIGN

Longitudinal serial in-depth qualitative interviews every 2-3 years for a median 7 (range 6-14) years following diagnosis.

SETTING

Four centres within the UK Protect trial.

PARTICIPANTS

Purposive sample of 20 men with localised PCa: median age at diagnosis 64 years (range 52-68); 15 (75%) had low-risk PCa; 12 randomly allocated to, 8 choosing AM. Eleven men continued with AM throughout the study period (median 7 years). Nine received radical treatment after a median 4 years (range 0.8-13.8 years).

INTERVENTION

AM: 3-monthly serum prostate-specific antigen (PSA)-level assessment (year 1), 6-12 monthly thereafter; increase in PSA ≥50% during previous 12 months or patient/clinician concern triggered review.

MAIN OUTCOMES

Thematic analysis of 73 interviews identified strategies to accommodate uncertainty and anxiety of living with untreated cancer; implications for patient care.

RESULTS

Men sought clarity, control or reassurance, with contextual factors mediating individual responses. Trust in the clinical team was critical for men in balancing anxiety and facilitating successful management change/continued monitoring. Only men from ProtecT were included; men outside ProtecT may have different experiences.

CONCLUSION

Men looked to clinicians for clarity, control and reassurance. Where provided, men felt comfortable continuing AM or having radical treatments when indicated. Clinicians build patient trust by clearly describing uncertainties, allowing patients control wherever possible and being aware of how context influences individual responses. Insights indicate need for supportive services to build trust and patient engagement over the long term.

The ProtecT randomised trial cost-effectiveness analysis comparing active monitoring, surgery, or radiotherapy for prostate cancer

BACKGROUND

There is limited evidence relating to the cost-effectiveness of treatments for localised prostate cancer.

METHODS

The cost-effectiveness of active monitoring, surgery, and radiotherapy was evaluated within the Prostate Testing for Cancer and Treatment (ProtecT) randomised controlled trial from a UK NHS perspective at 10 years' median follow-up. Prostate cancer resource-use collected from hospital records and trial participants was valued using UK reference-costs. QALYs (quality-adjusted-life-years) were calculated from patient-reported EQ-5D-3L measurements. Adjusted mean costs, QALYs, and incremental cost-effectiveness ratios were calculated; cost-effectiveness acceptability curves and sensitivity analyses addressed uncertainty; subgroup analyses considered age and disease-risk.

RESULTS

Adjusted mean QALYs were similar between groups: 6.89 (active monitoring), 7.09 (radiotherapy), and 6.91 (surgery). Active monitoring had lower adjusted mean costs (£5913) than radiotherapy (£7361) and surgery (£7519). Radiotherapy was the most likely (58% probability) cost-effective option at the UK NICE willingness-to-pay threshold (£20,000 per QALY). Subgroup analyses confirmed radiotherapy was cost-effective for older men and intermediate/high-risk disease groups; active monitoring was more likely to be the cost-effective option for younger men and low-risk groups.

CONCLUSIONS

Longer follow-up and modelling are required to determine the most cost-effective treatment for localised prostate cancer over a man's lifetime.

Active monitoring, radical prostatectomy and radical radiotherapy in PSA-detected clinically localised prostate cancer: the ProtecT three-arm RCT

BACKGROUND

Prostate cancer is the most common cancer among men in the UK. Prostate-specific antigen testing followed by biopsy leads to overdetection, overtreatment as well as undertreatment of the disease. Evidence of treatment effectiveness has lacked because of the paucity of randomised controlled trials comparing conventional treatments.

OBJECTIVES

To evaluate the effectiveness of conventional treatments for localised prostate cancer (active monitoring, radical prostatectomy and radical radiotherapy) in men aged 50-69 years.

DESIGN

A prospective, multicentre prostate-specific antigen testing programme followed by a randomised trial of treatment, with a comprehensive cohort follow-up.

SETTING

Prostate-specific antigen testing in primary care and treatment in nine urology departments in the UK.

PARTICIPANTS

Between 2001 and 2009, 228,966 men aged 50-69 years received an invitation to attend an appointment for information about the Prostate testing for cancer and Treatment (ProtecT) study and a prostate-specific antigen test; 82,429 men were tested, 2664 were diagnosed with localised prostate cancer, 1643 agreed to randomisation to active monitoring (n = 545), radical prostatectomy (n = 553) or radical radiotherapy (n = 545) and 997 chose a treatment.

INTERVENTIONS

The interventions were active monitoring, radical prostatectomy and radical radiotherapy.

TRIAL PRIMARY OUTCOME MEASURE

Definite or probable disease-specific mortality at the 10-year median follow-up in randomised participants.

SECONDARY OUTCOME MEASURES

Overall mortality, metastases, disease progression, treatment complications, resource utilisation and patient-reported outcomes.

RESULTS

There were no statistically significant differences between the groups for 17 prostate cancer-specific (p = 0.48) and 169 all-cause (p = 0.87) deaths. Eight men died of prostate cancer in the active monitoring group (1.5 per 1000 person-years, 95% confidence interval 0.7 to 3.0); five died of prostate cancer in the radical prostatectomy group (0.9 per 1000 person-years, 95% confidence interval 0.4 to 2.2 per 1000 person years) and four died of prostate cancer in the radical radiotherapy group (0.7 per 1000 person-years, 95% confidence interval 0.3 to 2.0 per 1000 person years). More men developed metastases in the active monitoring group than in the radical prostatectomy and radical radiotherapy groups: active monitoring, n = 33 (6.3 per 1000 person-years, 95% confidence interval 4.5 to 8.8); radical prostatectomy, n = 13 (2.4 per 1000 person-years, 95% confidence interval 1.4 to 4.2 per 1000 person years); and radical radiotherapy, n = 16 (3.0 per 1000 person-years, 95% confidence interval 1.9 to 4.9 per 1000 person-years; p = 0.004). There were higher rates of disease progression in the active monitoring group than in the radical prostatectomy and radical radiotherapy groups: active monitoring (n = 112; 22.9 per 1000 person-years, 95% confidence interval 19.0 to 27.5 per 1000 person years); radical prostatectomy (n = 46; 8.9 per 1000 person-years, 95% confidence interval 6.7 to 11.9 per 1000 person-years); and radical radiotherapy (n = 46; 9.0 per 1000 person-years, 95% confidence interval 6.7 to 12.0 per 1000 person years; p < 0.001). Radical prostatectomy had the greatest impact on sexual function/urinary continence and remained worse than radical radiotherapy and active monitoring. Radical radiotherapy's impact on sexual function was greatest at 6 months, but recovered somewhat in the majority of participants. Sexual and urinary function gradually declined in the active monitoring group. Bowel function was worse with radical radiotherapy at 6 months, but it recovered with the exception of bloody stools. Urinary voiding and nocturia worsened in the radical radiotherapy group at 6 months but recovered. Condition-specific quality-of-life effects mirrored functional changes. No differences in anxiety/depression or generic or cancer-related quality of life were found. At the National Institute for Health and Care Excellence threshold of £20,000 per quality-adjusted life-year, the probabilities that each arm was the most cost-effective option were 58% (radical radiotherapy), 32% (active monitoring) and 10% (radical prostatectomy).

LIMITATIONS

A single prostate-specific antigen test and transrectal ultrasound biopsies were used. There were very few non-white men in the trial. The majority of men had low- and intermediate-risk disease. Longer follow-up is needed.

CONCLUSIONS

At a median follow-up point of 10 years, prostate cancer-specific mortality was low, irrespective of the assigned treatment. Radical prostatectomy and radical radiotherapy reduced disease progression and metastases, but with side effects. Further work is needed to follow up participants at a median of 15 years.

Adjuvant chemotherapy in upper tract urothelial carcinoma (the POUT trial): a phase 3, open-label, randomised controlled trial

BACKGROUND

Urothelial carcinomas of the upper urinary tract (UTUCs) are rare, with poorer stage-for-stage prognosis than urothelial carcinomas of the urinary bladder. No international consensus exists on the benefit of adjuvant chemotherapy for patients with UTUCs after nephroureterectomy with curative intent. The POUT (Peri-Operative chemotherapy versus sUrveillance in upper Tract urothelial cancer) trial aimed to assess the efficacy of systemic platinum-based chemotherapy in patients with UTUCs.

METHODS

We did a phase 3, open-label, randomised controlled trial at 71 hospitals in the UK. We recruited patients with UTUC after nephroureterectomy staged as either pT2-T4 pN0-N3 M0 or pTany N1-3 M0. We randomly allocated participants centrally (1:1) to either surveillance or four 21-day cycles of chemotherapy, using a minimisation algorithm with a random element. Chemotherapy was either cisplatin (70 mg/m2) or carboplatin (area under the curve [AUC]4·5/AUC5, for glomerular filtration rate <50 mL/min only) administered intravenously on day 1 and gemcitabine (1000 mg/m2) administered intravenously on days 1 and 8; chemotherapy was initiated within 90 days of surgery. Follow-up included standard cystoscopic, radiological, and clinical assessments. The primary endpoint was disease-free survival analysed by intention to treat with a Peto-Haybittle stopping rule for (in)efficacy. The trial is registered with ClinicalTrials.gov, NCT01993979. A preplanned interim analysis met the efficacy criterion for early closure after recruitment of 261 participants.

FINDINGS

Between June 19, 2012, and Nov 8, 2017, we enrolled 261 participants from 57 of 71 open study sites. 132 patients were assigned chemotherapy and 129 surveillance. One participant allocated chemotherapy withdrew consent for data use after randomisation and was excluded from analyses. Adjuvant chemotherapy significantly improved disease-free survival (hazard ratio 0·45, 95% CI 0·30-0·68; p=0·0001) at a median follow-up of 30·3 months (IQR 18·0-47·5). 3-year event-free estimates were 71% (95% CI 61-78) and 46% (36-56) for chemotherapy and surveillance, respectively. 55 (44%) of 126 participants who started chemotherapy had acute grade 3 or worse treatment-emergent adverse events, which accorded with frequently reported events for the chemotherapy regimen. Five (4%) of 129 patients managed by surveillance had acute grade 3 or worse emergent adverse events. No treatment-related deaths were reported.

INTERPRETATION

Gemcitabine-platinum combination chemotherapy initiated within 90 days after nephroureterectomy significantly improved disease-free survival in patients with locally advanced UTUC. Adjuvant platinum-based chemotherapy should be considered a new standard of care after nephroureterectomy for this patient population.

Ten-year Mortality, Disease Progression, and Treatment-related Side Effects in Men with Localised Prostate Cancer from the ProtecT Randomised Controlled Trial According to Treatment Received

BACKGROUND

The ProtecT trial reported intention-to-treat analysis of men with localised prostate cancer (PCa) randomly allocated to active monitoring (AM), radical prostatectomy, and external beam radiotherapy.

OBJECTIVE

To determine report outcomes according to treatment received in men in randomised and treatment choice cohorts.

DESIGN, SETTING, AND PARTICIPANTS

This study focuses on secondary care. Men with clinically localised prostate cancer at one of nine UK centres were invited to participate in the treatment trial comparing AM, radical prostatectomy, and radiotherapy.

INTERVENTION

Two cohorts included 1643 men who agreed to be randomised; 997 declined randomisation and chose treatment.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

Health-related quality of life impacts on urinary, bowel, and sexual function were assessed using patient-reported outcome measures. Analysis was carried out based on treatment received for each cohort and on pooled estimates using meta-analysis. Differences were estimated with adjustment for known prognostic factors using propensity scores.

RESULTS AND LIMITATIONS

According to treatment received, more men receiving AM died of PCa (AM 1.85%, surgery 0.67%, radiotherapy 0.73%), whilst this difference remained consistent with chance in the randomised cohort (p=0.08); stronger evidence was found in the exploratory analyses (randomised plus choice cohort) when AM was compared with the combined radical treatment group (p=0.003). There was also strong evidence that metastasis (AM 5.6%, surgery 2.4%, radiotherapy 2.7%) and disease progression (AM 20.35%, surgery 5.87%, radiotherapy 6.62%) were more common in the AM group. Compared with AM, there were higher risks of sexual dysfunction (95% at 6mo) and urinary incontinence (55% at 6mo) after surgery, and of sexual dysfunction (88% at 6mo) and bowel dysfunction (5% at 6mo) after radiotherapy. The key limitations are the potential for bias when comparing groups defined by treatment received and outdating of the interventions being evaluated during the lengthy follow-up required in trials of screen-detected PCa.

CONCLUSIONS

Analyses according to treatment received showed increased rates of disease-related events and lower rates of patient-reported harms in men managed by AM compared with men managed by radical treatment, and stronger evidence of greater PCa mortality in the AM group.

PATIENT SUMMARY

More than 90 out of every 100 men with localised prostate cancer do not die of prostate cancer within 10yr, irrespective of whether treatment is by means of monitoring, surgery, or radiotherapy. Side effects on sexual and bladder function are much better after active monitoring, but the risks of spreading of prostate cancer are more common.

Can subcentimetre ultrasound detected angiomyolipomas be safely disregarded?

AIM

To optimise follow-up by dismissing lesions on baseline ultrasound (US) if renal lesions conform to US criteria of an angiomyolipoma (AML).

METHOD AND MATERIALS

The present study was a 10-year retrospective review of patients who were found to have incidental hyperechoic renal lesions on US to ascertain the outcome from subsequent imaging, clinical encounters, and cancer registrations. Exclusions included renal calculi, tuberous sclerosis, Von-Hippel-Lindau, or a known cancer.

RESULTS

After excluding 39 patients, 1,493 patients were identified. One hundred and sixty had more than one lesion with 87 patients having bilateral lesions. Regardless of indication, 889 patients had subsequent imaging within 5 years (59.5%). The average size of all AMLs was 13.2 mm. In the group with lesions that were <10 mm (807), 438 had imaging follow-up with an average follow-up time of 1.5 years. Mean lesion size in this group was 7 mm, with an average increase of <0.5 mm on follow-up. No lesions were found to be malignant on subsequent imaging nor did any of these patients have a subsequent renal cancer diagnosis registered at local multidisciplinary team meetings.

CONCLUSION

No incidental subcentimetre hyperechoic renal lesion with imaging characteristics of an AML demonstrated significant growth or developed into a malignancy on follow-up.

Results of POUT: A phase III randomised trial of perioperative chemotherapy versus surveillance in upper tract urothelial cancer (UTUC)

407

Background: The role of post nephro-ureterectomy (NU) treatment for UTUC is unclear. POUT (CRUK/11/027; NCT01993979) addresses whether adjuvant chemotherapy improves disease free survival (DFS) for pts with histologically confirmed pT2-T4 N0-3 M0 UTUC. Methods: Pts (max n = 345) ≤90 days post NU were randomised (1:1) to 4 cycles of gemcitabine-cisplatin (gemcitabine-carboplatin if GFR 30-49ml/min) or surveillance with subsequent chemotherapy if required. Pts had 6 monthly cross sectional imaging and cystoscopy for the first 2 years, then annually to 5 years. Toxicity was assessed by CTCAE v4. Primary endpoint was DFS. The trial was powered to detect a hazard ratio (HR) of 0.65 (i.e. improvement in 3 year DFS from 40% to 55%; 2-sided alpha = 5%, 80% power) with Peto-Haybittle (p < 0.001) early stopping rules for efficacy & inefficacy. Secondary endpoints included metastasis-free survival (PFS), overall survival (OS), toxicity & quality of life. Results: Between May 2012 & Sept 2017, 248 pts were recruited (123 surveillance; 125 chemotherapy) at 57 UK centres. In Oct 2017, the independent trial oversight committees recommended POUT close to recruitment as data collected thus far (data snapshot 05/09/2017) met the early stopping rule for efficacy. At the time of interim analysis, median follow-up was 17.6 months (IQR 7.5-33.6). Pts had median age 69 years (range 36-88), 30% pT2, 65% pT3; 91% pN0;. Grade ≥3 toxicities were reported in 60% chemotherapy pts & 24% surveillance pts. 47/123 (surveillance) & 29/125 (chemotherapy) DFS events were reported; unadjusted HR = 0.47 (95% CI: 0.29, 0.74) in favour of chemotherapy (log-rank p = 0.0009). Two year DFS was 51% for surveillance (95% CI: 39, 61) and 70% for chemotherapy (95% CI: 58, 79). PFS favoured chemotherapy: HR = 0.49 (95% CI: 0.30, 0.79, p = 0.003). Conclusions: Adjuvant chemotherapy improved PFS in UTUC. POUT is the largest randomised trial in this pt population; the trial was terminated early because of efficacy favouring the chemotherapy arm. Whilst follow up for OS continues, this should be considered a new standard of care in these patients. Clinical trial information: ISRCTN98387754.

The Epidemiology of urological cancer 2001–2013

Background:

The purpose of the NCRAS Urological Cancer Site-Specific Clinical Reference Group (SSCRG) is to link the knowledge of clinicians with the large amount of routine data collected by cancer registration. This study considers the latest available data and trends in incidence, mortality and survival and offers interpretation of findings in a clinical context.

Methods:

New diagnoses of urological cancer in England for 2001 to 2013 were extracted from the National Cancer Registration and Analysis Service (NCRAS). Deaths were counted from Office for National Statistics (ONS) data for the same years. Directly age-standardised rates (ASRs) and net survival were calculated.

Results:

Prostate cancer incidence has increased to 40,000 cases per year. Mortality rates are falling and hence the improvement seen in five-year survival is likely to be due to changes in treatment rather than artefact. Bladder cancer (including CIS and pTa disease) shows a stable incidence and decreasing mortality rates. Survival from T1–T4 bladder cancer is stable. There has been a marked rise in kidney cancer incidence in both sexes with a stable mortality. The stable mortality suggests that improved five-year survival may be an artefact due to increased detection as a result of more widespread use of diagnostic imaging. Incidence of upper-urinary-tract cancer has risen both for invasive and non-invasive disease, and mortality in men has risen for invasive disease. This may be down to better recognition and attribution of disease. Testicular cancer has shown little change. Deaths are now rare, and survival is the highest for any cancer. There have been no significant changes in penis cancer, which remains the rarest urological cancer.

Conclusion:

The epidemiological data suggest a generally improving picture for urological cancer. However, there are some areas which require further consideration. Population-based studies can show variation in rare cancers and highlight previously unrecognised inequalities.

Cardiovascular outcomes in kidney cancer patients

Introduction:

In the surgical management of small renal tumours, current guidelines recommend that partial nephrectomy should be the preferred option wherever possible. This is based on evidence suggesting improved quality of life outcomes, morbidity and mortality and equivalent oncological outcomes when compared with radical nephrectomy. Chronic kidney disease is a significant risk factor for cardiovascular disease and subsequent mortality. This study explored differences in cardiac-related events and co-morbidity, using linked registry data for patients undergoing radical or partial nephrectomy for T1 renal tumours.

Methods:

Data from the National Cancer Registration Service was searched to identify T1 renal cancer diagnoses between 1999 and 2012. This data was matched against hospital episode statistics to identify those patients who had undergone radical or partial nephrectomy between 1999 and 2013 using OPCS codes. Data was collected on cardiac-related admissions and deaths in nephrectomy patients. Equivalent data was also collected for the general population to allow age-standardized comparison. Charlson score was used as a proxy for pre-operative co-morbidity.

Results:

Radical/partial nephrectomy patients had a greater risk of cardiac-related admissions compared with the general population (relative risk (RR) 3.32, 95% confidence interval (CI) 3.24–3.40), but with no increase in cardiac-related deaths (RR 0.84, 95% CI 0.70–1.01). There was no difference in the admission risk, or death, comparing radical or partial nephrectomy for T1 renal tumours (RR 1.02, 95% CI 0.88–1.17) using ‘time to event’ analysis. There was no difference in the comorbidity index between radical nephrectomy and partial nephrectomy patients.

Conclusion:

The higher incidence of cardiac-related admissions seen for radical/partial nephrectomy patients may be explained by a higher proportion of patients with medical illnesses including cardiovascular risk factors (hypertension, diabetes) undergoing renal imaging. The absence of a difference between the radical nephrectomy and partial nephrectomy groups supports the phenomenon of surgically-induced chronic kidney disease, which may not have the same morbidity implications as medically-induced chronic kidney disease.

Variation in usage of radical prostatectomy and radical radiotherapy for men with locally advanced prostate cancer

Locally advanced prostate cancer is defined as primary tumours extending outside the prostate gland to the surrounding tissues or seminal vesicles but without spread beyond the pelvic region. With radical treatment there is good prospect of cure. Radiotherapy in combination with hormone therapy is well established, but specific NICE guidelines have only recently been published. The guidelines recommend offering either radical prostatectomy (RP), possibly with adjuvant radiotherapy, or radical radiotherapy (RT) with neo-adjuvant hormone therapy as treatment for men with locally advanced prostate cancer. Given that guidelines on managing locally advanced prostate cancer have recently changed, we wanted to quantify the baseline variation in use of radical treatments for this patient group.

Methods:

Men with T3/T4 N0 M0 prostate cancer who were diagnosed in 2010–2012 were identified using data from the National Cancer Registration and Analysis Service (NCRAS). Data on age, ethnicity, deprivation, Charlson comorbidity score, Strategic Clinical Network (SCN) of residence, and treatments delivered were extracted. A multivariable logistic regression was undertaken to identify important variables.

Results:

Overall, 1692 (14%) of men in the cohort had a record of radical prostatectomy. A total of 6212 (52%) had a record of curative RT. In a regression model each decade increase in age yielded odds of 0.39 ( p < 0.001) for receiving radical treatment. Black men were only half as likely as white men to receive radical treatment (OR = 0.54; p < 0.001). Deprivation, comorbidity and SCN of residence had smaller effects. The variation observed in radical treatment between SCNs largely disappeared once the multiple variables were accounted for.

Conclusion:

Radical treatments vary by 71% to 85% between networks for men aged 60–69 years. Given that men >80 years made up 12% of the study population and only 6% had a Charlson comorbidity score >0, there is a possibility that some men with ‘clinically significant’ disease are undertreated.

Non-transitional cell carcinoma only partly explains adverse survival outcomes in females with T1–T4 bladder cancer: A summary of UK epidemiological data

Objective:

The objective of this article is to investigate why bladder cancer (BC) survival is worse in females using national cancer datasets.

Patients and methods:

All BC diagnoses since the year 2000 were identified from the National Cancer Data Repository (NCDR) using ICD-10 Code C67 (Bladder cancer T1–T4). Age-standardised relative survival rates for males and females diagnosed with BC between 2000 and 2010 were obtained from Public Health England.

Results:

Five-year relative survival of men with transitional cell carcinoma (TCC) BC (Code C67) was 61%, but in females was significantly less at 52%. One in four female BC (27%) patients are non-TCC, proportionately far more compared to 1:6 (16%) non-TCC BC in males. Five-year relative survival in non-TCC BC subtypes was notably reduced to 23% in females compared to 35% in men. Only 47% of patients with non-TCC BC receive surgical treatment compared to 82% for all BC.

Conclusion:

Relative survival from non-TCC BC is significantly less than the overall survival from TCC BC. Female patients with invasive BC have a worse survival than men. This is partly explained by the proportionately higher incidence of non-TCC BC in females, but women with TCC BC also have worse outcomes so other factors must contribute. Female gender should be recognised as an adverse risk factor in BC survival and influence management decisions.

10-Year Outcomes after Monitoring, Surgery, or Radiotherapy for Localized Prostate Cancer

BACKGROUND

The comparative effectiveness of treatments for prostate cancer that is detected by prostate-specific antigen (PSA) testing remains uncertain.

METHODS

We compared active monitoring, radical prostatectomy, and external-beam radiotherapy for the treatment of clinically localized prostate cancer. Between 1999 and 2009, a total of 82,429 men 50 to 69 years of age received a PSA test; 2664 received a diagnosis of localized prostate cancer, and 1643 agreed to undergo randomization to active monitoring (545 men), surgery (553), or radiotherapy (545). The primary outcome was prostate-cancer mortality at a median of 10 years of follow-up. Secondary outcomes included the rates of disease progression, metastases, and all-cause deaths.

RESULTS

There were 17 prostate-cancer-specific deaths overall: 8 in the active-monitoring group (1.5 deaths per 1000 person-years; 95% confidence interval [CI], 0.7 to 3.0), 5 in the surgery group (0.9 per 1000 person-years; 95% CI, 0.4 to 2.2), and 4 in the radiotherapy group (0.7 per 1000 person-years; 95% CI, 0.3 to 2.0); the difference among the groups was not significant (P=0.48 for the overall comparison). In addition, no significant difference was seen among the groups in the number of deaths from any cause (169 deaths overall; P=0.87 for the comparison among the three groups). Metastases developed in more men in the active-monitoring group (33 men; 6.3 events per 1000 person-years; 95% CI, 4.5 to 8.8) than in the surgery group (13 men; 2.4 per 1000 person-years; 95% CI, 1.4 to 4.2) or the radiotherapy group (16 men; 3.0 per 1000 person-years; 95% CI, 1.9 to 4.9) (P=0.004 for the overall comparison). Higher rates of disease progression were seen in the active-monitoring group (112 men; 22.9 events per 1000 person-years; 95% CI, 19.0 to 27.5) than in the surgery group (46 men; 8.9 events per 1000 person-years; 95% CI, 6.7 to 11.9) or the radiotherapy group (46 men; 9.0 events per 1000 person-years; 95% CI, 6.7 to 12.0) (P<0.001 for the overall comparison).

CONCLUSIONS

At a median of 10 years, prostate-cancer-specific mortality was low irrespective of the treatment assigned, with no significant difference among treatments. Surgery and radiotherapy were associated with lower incidences of disease progression and metastases than was active monitoring.

Patient-Reported Outcomes after Monitoring, Surgery, or Radiotherapy for Prostate Cancer

BACKGROUND

Robust data on patient-reported outcome measures comparing treatments for clinically localized prostate cancer are lacking. We investigated the effects of active monitoring, radical prostatectomy, and radical radiotherapy with hormones on patient-reported outcomes.

METHODS

We compared patient-reported outcomes among 1643 men in the Prostate Testing for Cancer and Treatment (ProtecT) trial who completed questionnaires before diagnosis, at 6 and 12 months after randomization, and annually thereafter. Patients completed validated measures that assessed urinary, bowel, and sexual function and specific effects on quality of life, anxiety and depression, and general health. Cancer-related quality of life was assessed at 5 years. Complete 6-year data were analyzed according to the intention-to-treat principle.

RESULTS

The rate of questionnaire completion during follow-up was higher than 85% for most measures. Of the three treatments, prostatectomy had the greatest negative effect on sexual function and urinary continence, and although there was some recovery, these outcomes remained worse in the prostatectomy group than in the other groups throughout the trial. The negative effect of radiotherapy on sexual function was greatest at 6 months, but sexual function then recovered somewhat and was stable thereafter; radiotherapy had little effect on urinary continence. Sexual and urinary function declined gradually in the active-monitoring group. Bowel function was worse in the radiotherapy group at 6 months than in the other groups but then recovered somewhat, except for the increasing frequency of bloody stools; bowel function was unchanged in the other groups. Urinary voiding and nocturia were worse in the radiotherapy group at 6 months but then mostly recovered and were similar to the other groups after 12 months. Effects on quality of life mirrored the reported changes in function. No significant differences were observed among the groups in measures of anxiety, depression, or general health-related or cancer-related quality of life.

CONCLUSIONS

In this analysis of patient-reported outcomes after treatment for localized prostate cancer, patterns of severity, recovery, and decline in urinary, bowel, and sexual function and associated quality of life differed among the three groups.

Mortality Among Men with Advanced Prostate Cancer Excluded from the ProtecT Trial

Background

Early detection and treatment of asymptomatic men with advanced and high-risk prostate cancer (PCa) may improve survival rates.

Objective

To determine outcomes for men diagnosed with advanced PCa following prostate-specific antigen (PSA) testing who were excluded from the ProtecT randomised trial.

Design, setting, and participants

Mortality was compared for 492 men followed up for a median of 7.4 yr to a contemporaneous cohort of men from the UK Anglia Cancer Network (ACN) and with a matched subset from the ACN.

Outcome measurements and statistical analysis

PCa-specific and all-cause mortality were compared using Kaplan-Meier analysis and Cox's proportional hazards regression.

Results and limitations

Of the 492 men excluded from the ProtecT cohort, 37 (8%) had metastases (N1, M0 = 5, M1 = 32) and 305 had locally advanced disease (62%). The median PSA was 17 μg/l. Treatments included radical prostatectomy (RP; n = 54; 11%), radiotherapy (RT; n = 245; 50%), androgen deprivation therapy (ADT; n = 122; 25%), other treatments (n = 11; 2%), and unknown (n = 60; 12%). There were 49 PCa-specific deaths (10%), of whom 14 men had received radical treatment (5%); and 129 all-cause deaths (26%). In matched ProtecT and ACN cohorts, 37 (9%) and 64 (16%), respectively, died of PCa, while 89 (22%) and 103 (26%) died of all causes. ProtecT men had a 45% lower risk of death from PCa compared to matched cases (hazard ratio 0.55, 95% confidence interval 0.38–0.83; p = 0.0037), but mortality was similar in those treated radically. The nonrandomised design is a limitation.

Conclusions

Men with PSA-detected advanced PCa excluded from ProtecT and treated radically had low rates of PCa death at 7.4-yr follow-up. Among men who underwent nonradical treatment, the ProtecT group had a lower rate of PCa death. Early detection through PSA testing, leadtime bias, and group heterogeneity are possible factors in this finding.

Patient summary

Prostate cancer that has spread outside the prostate gland without causing symptoms can be detected via prostate-specific antigen testing and treated, leading to low rates of death from this disease.

Closing the Gender Gap: Can We Improve Bladder Cancer Survival in Women? - A Systematic Review of Diagnosis, Treatment and Outcomes

INTRODUCTION

Despite recent attention, there are no gender specific guidelines to address the disparity in bladder cancer survival between the sexes. The focus of this review was to identify areas of clinical practice that may influence bladder cancer outcomes and to provide evidence-based recommendations to improve bladder cancer survival in women.

METHOD

A systematic search of MEDLINE was conducted to identify studies related to referral, diagnosis, treatment and outcomes of patients with bladder cancer with particular reference to gender differences.

RESULTS

Patients' knowledge of key signs and symptoms of bladder cancer is poor. There is evidence that there is a gender difference in referral patterns both at patient and primary care level. The presence of cystits, in particular, delays referral. Treatment and surveillance of high-risk non-muscle invasive cancers is variable and non-urothelial bladder cancer, which has higher incidence in women is more likely to be treated non-operatively than urothelial bladder cancer.

CONCLUSION

We have offered recommendations to improve patient education and streamline referrals and suggested considerations for treatment of high-risk cancers to help improve survival in female bladder cancer patients.

A unique case of gliomatosis peritonei in a man, following a retroperitoneal teratoma

We present an unusual case of a 56-year-old man presenting with abdominal swelling. Imaging revealed a large abdominal 23 cm cystic mass, which radiologically appeared to be related to the small bowel. There was an attempted surgical removal by the general surgeons. It was histologically confirmed as a retroperitoneal cystic teratoma with immature neural elements with incomplete resection margins. Residual disease was found at re-imaging 3 months later and a further block dissection was performed, with histology confirming recurrence. Thirteen months later, imaging revealed recurrent disease with peritoneal involvement. At laparoscopic exploration, there was peritoneal seeding, and biopsies confirmed a diagnosis of gliomatosis peritonei, secondary to the retroperitoneal teratoma. The patient proceeded to have combination chemotherapy to achieve stable disease on imaging. A month after completion, sadly, the disease progressed; the patient received best supportive care.

Complication of treatment of carcinoma in situ of the bladder with photodynamic targeted cystodiathermy

We report two cases of bladder contracture following photodynamic or 'blue light' detection and cystodiathermy for bladder carcinoma in situ. These patients were unsuitable for treatment with immunotherapy/chemotherapy or had disease recurrence following such treatment. Radical cystectomy was not a treatment option in either patient. Each underwent serial photodynamic cystodiathermy over a three-year period. Neither patient developed muscle invasive disease. However, treatment resulted in contracture of the bladder and incontinence of urine. Patients need to be fully aware of this potential complication in order to make informed choices about their care.

Cardiovascular outcomes in patients with locally advanced and metastatic prostate cancer treated with luteinising-hormone-releasing-hormone agonists or transdermal oestrogen: the randomised, phase 2 MRC PATCH trial (PR09)

BACKGROUND

Luteinising-hormone-releasing-hormone agonists (LHRHa) to treat prostate cancer are associated with long-term toxic effects, including osteoporosis. Use of parenteral oestrogen could avoid the long-term complications associated with LHRHa and the thromboembolic complications associated with oral oestrogen.

METHODS

In this multicentre, open-label, randomised, phase 2 trial, we enrolled men with locally advanced or metastatic prostate cancer scheduled to start indefinite hormone therapy. Randomisation was by minimisation, in a 2:1 ratio, to four self-administered oestrogen patches (100 μg per 24 h) changed twice weekly or LHRHa given according to local practice. After castrate testosterone concentrations were reached (1·7 nmol/L or lower) men received three oestrogen patches changed twice weekly. The primary outcome, cardiovascular morbidity and mortality, was analysed by modified intention to treat and by therapy at the time of the event to account for treatment crossover in cases of disease progression. This study is registered with ClinicalTrials.gov, number NCT00303784.

FINDINGS

85 patients were randomly assigned to receive LHRHa and 169 to receive oestrogen patches. All 85 patients started LHRHa, and 168 started oestrogen patches. At 3 months, 70 (93%) of 75 receiving LHRHa and 111 (92%) of 121 receiving oestrogen had achieved castrate testosterone concentrations. After a median follow-up of 19 months (IQR 12-31), 24 cardiovascular events were reported, six events in six (7·1%) men in the LHRHa group (95% CI 2·7-14·9) and 18 events in 17 (10·1%) men in the oestrogen-patch group (6·0-15·6). Nine (50%) of 18 events in the oestrogen group occurred after crossover to LHRHa. Mean 12-month changes in fasting glucose concentrations were 0·33 mmol/L (5·5%) in the LHRHa group and -0·16 mmol/L (-2·4%) in the oestrogen-patch group (p=0·004), and for fasting cholesterol were 0·20 mmol/L (4·1%) and -0·23 mmol/L (-3·3%), respectively (p<0·0001). Other adverse events reported by 6 months included gynaecomastia (15 [19%] of 78 patients in the LHRHa group vs 104 [75%] of 138 in the oestrogen-patch group), hot flushes (44 [56%] vs 35 [25%]), and dermatological problems (10 [13%] vs 58 [42%]).

INTERPRETATION

Parenteral oestrogen could be a potential alternative to LHRHa in management of prostate cancer if efficacy is confirmed. On the basis of our findings, enrolment in the PATCH trial has been extended, with a primary outcome of progression-free survival.

Results of a quantitative survey to explore both perceptions of the purposes of follow-up and preferences for methods of follow-up delivery among service users, primary care practitioners and specialist clinicians after cancer treatment

AIMS

To ascertain perceptions of reasons for follow-up after cancer treatment among service users (patients and carers), primary care practitioners and specialist clinicians (doctors and specialist nurses) and to identify levels of preference for different models of follow-up and the effect of an individual's experience on preferred models.

MATERIALS AND METHODS

A national survey designed to meet the needs of each key respondent group was carried out after a structured literature review, an extensive consultation process and a pilot scheme. Respondents were asked to assess their degree of preference for 10 pre-selected indications for follow-up. Eight models of follow-up were also identified and respondents were asked to state their experience and preference for each type. The questionnaire was distributed nationally via the 34 cancer networks in England and was available both online and in hard copy (postal). The uptake for the electronic format was in the main by primary care practitioners and specialist clinicians. Service users preferred the paper (postal) format. The survey was also publicised through the primary care and patient partnership forums at a Cancer Network Development event.

RESULTS

In total, 2928 responses were received, comprising service users (21% of the sample), primary care practitioners (32%) and specialist clinicians (47%). Eighty-six per cent of responses were received from the 10 strategic health authorities in England, with the remaining 14% from Scotland, Wales and The Isle of Man. The responses from Scotland, Wales and the Isle of Man generally occurred where they interfaced with English cancer networks or had been engaged through word of mouth by colleagues. Among all respondents the main aims of cancer follow-up were considered to be: (1) to monitor for early complications after treatment; (2) to detect recurrences early; (3) to detect late effects of treatment. The most commonly experienced method of follow-up among all respondent groups was outpatient review with a doctor. This was considered to be the most preferred follow-up option among service users (86%). The least preferred option among service users was postal follow-up (32%). Primary care practitioners and specialist clinicians were more likely than service users to have experienced alternative methods of follow-up, such as telephone follow-up, self-triggered referral and non-specialist follow-up. These models were highly rated by those who had experience of them.

CONCLUSIONS

There was a reasonable level of consensus between service users, primary care practitioners and specialist clinicians as to the reasons for follow-up. Service users seemed to have higher expectations of follow-up, particularly in relation to detecting recurrences early. As respondents were more likely to prefer a method of follow-up delivery that they had experienced than one they had not; there could be resistance to change from established methods to new methods without adequate explanation. This suggests that the communication of new methods could be critical to their successful introduction.

Men's and carers' experiences of care for prostate cancer: a narrative literature review

OBJECTIVE

To review studies of patients' and carers' experience of prostate cancer care.

DESIGN

Narrative literature review.

METHODS

Search strategies were developed for the following databases: MEDLINE (1966-2006), EMBASE (1980-2006), CINAHL (1982-2006) and PsycINFO (1987-2006). A search of SIGLE (System for Information on Grey Literature in Europe) was also undertaken. Experience was defined as patients' and carers' reports of how care was organized and delivered to meet their needs. A narrative summary of the included papers was undertaken.

RESULTS

A total of 90 relevant studies were identified. Most studies reported on experiences of screening, diagnosis, the treatment decision, treatment and post-initial treatment. Few studies reported on experiences of the stages of referral, testing, and further treatment and palliative care, and no studies reported on monitoring or terminal care.

CONCLUSIONS

Although some phases of care have not been investigated in detail, there is evidence that: (i) many patients have a low level of knowledge of prostate cancer; (ii) patients with prostate cancer and their carers need information throughout the care pathway to enable them to understand the diagnosis, treatment options, self-care and support available; and (iii) increasing patient knowledge and understanding of prostate cancer (e.g. through interventions) are often associated with a more active role in decision making (e.g. screening, treatment decision).

The Prostate Care Questionnaire for Carers (PCQ-C): reliability, validity and acceptability

BACKGROUND

Patient experience is commonly monitored in evaluating and improving health care, but the experience of carers (partners/relatives/friends) is rarely monitored even though the role of carers can often be substantial. For carers to fulfil their role it is necessary to address their needs. This paper describes an evaluation of the reliability, validity and acceptability of the PCQ-C, a newly developed instrument designed to measure the experiences of carers of men with prostate cancer.

METHODS

The reliability, acceptability and validity of the PCQ-C were tested through a postal survey and interviews with carers. The PCQ-C was posted to 1087 prostate cancer patients and patients were asked to pass the questionnaire on to their carer. Non-responders received one reminder. To assess test-retest reliability, 210 carers who had responded to the questionnaire were resent it a second time three weeks later. A subsample of nine carers from patients attending one hospital took part in qualitative interviews to assess validity and acceptability of the PCQ-C. Acceptability to service providers was evaluated based on four hospitals' experiences of running a survey using the PCQ-C.

RESULTS

Questionnaires were returned by 514 carers (47.3%), and the majority of questions showed less than 10% missing data. Across the sections of the questionnaire internal consistency was high (Cronbach's alpha ranging from 0.80 to 0.89), and test-retest stability showed moderate to high stability (intraclass correlation coefficients ranging from 0.52 to 0.83). Interviews of carers indicated that the PCQ-C was valid and acceptable. Feedback from hospitals indicated that they found the questionnaire useful, and highlighted important considerations for its future use as part of quality improvement initiatives.

CONCLUSIONS

The PCQ-C has been found to be acceptable to carers and service providers having been used successfully in hospitals in England. It is ready for use to measure the aspects of care that need to be addressed to improve the quality of prostate cancer care, and for research.

The prostate care questionnaire for patients (PCQ-P): reliability, validity and acceptability

Background

In England, prostate cancer patients report worse experience of care than patients with other cancers. However, no standard measure of patient experience of prostate cancer care is currently available. This paper describes an evaluation of the reliability, validity and acceptability of the PCQ-P, a newly developed instrument designed to measure patient experience of prostate cancer care.

Methods

The reliability, acceptability and validity of the PCQ-P were tested through a postal survey and interviews with patients. The PCQ-P was posted to 1087 prostate cancer patients varying in age, occupation, and overall health status, sampled from five hospitals in England. Nonresponders received one reminder. To assess criterion validity, 935 patients were also sent sections of the National Centre for Social Research Shortened Questionnaire; and to assess test-retest reliability, 296 patients who responded to the questionnaire were resent it a second time three weeks later. A subsample of 20 prostate cancer patients from one hospital took part in qualitative interviews to assess validity and acceptability of the PCQ-P. Acceptability to service providers was evaluated based on four hospitals' experiences of running a survey using the PCQ-P.

Results

Questionnaires were returned by 865 patients (69.2%). Missing data was low across the sections, with the proportion of patients completing less than 50% of each section ranging from 4.5% to 6.9%. Across the sections of the questionnaire, internal consistency was moderate to high (Cronbach's alpha ranging from 0.63 to 0.80), and test-retest stability was acceptable (intraclass correlation coefficients ranging from 0.57 to 0.73). Findings on criterion validity were significant. Patient interviews indicated that the PCQ-P had high face validity and acceptability. Feedback from hospitals indicated that they found the questionnaire useful, and highlighted important considerations for its future use as part of quality improvement initiatives.

Conclusion

The PCQ-P has been found to be acceptable to patients and service providers, and is ready for use for the measurement of patient experience in routine practice, service improvement programmes, and research.

Early hormonal data from a multicentre phase II trial using transdermal oestrogen patches as first-line hormonal therapy in patients with locally advanced or metastatic prostate cancer

OBJECTIVE

To assess the hormonal effects of Fem7 (Merck, KGaA, Darmstadt, Germany) 100 microg transdermal oestrogen patches on men undergoing first-line androgen-deprivation therapy for prostate cancer.

PATIENTS AND METHODS

PATCH is a multicentre, randomized, phase II trial for men with locally advanced or metastatic prostate cancer, comparing luteinizing hormone-releasing hormone agonist therapy with oestrogen patches. To assess the dosing schedule for the patches, as this was the first time that this brand of patch had been used in men, and to reassure patients and participating clinicians, the Independent Data Monitoring Committee agreed to early release of hormonal data from this study.

RESULTS

Oestradiol, testosterone and prostate-specific antigen (PSA) levels are presented for the first group of 14 patients who received the patches (with 1 withdrawal) and for whom there were > or =12 weeks of follow-up by March 2007. After 12 weeks, testosterone levels (nmol/L) in eight of the 13 patients were <1.7, two were 1.7-2 and three were >2. The median (range) serum oestradiol levels was 442 (52.1-1542) pmol/L and all patients had a PSA response, with eight having a PSA level of <4 ng/mL.

CONCLUSION

These results confirm that oestrogen patches produce castrate levels of testosterone and concomitant PSA responses. They also highlighted the potential differences between different brands of oestrogen patches, and the need to monitor hormonal response, toxicity and efficacy until more experience with oestrogen patches for this clinical indication is obtained. The number of patches recommended in the PATCH study has now been increased.

A Randomized Trial of Radical Radiotherapy for the Management of pT1G3 NXM0 Transitional Cell Carcinoma of the Bladder

PURPOSE

We conducted a multicenter randomized trial in the United Kingdom to determine the efficacy of radical radiotherapy in reducing the incidence of progression of pT1G3 transitional cell carcinoma of the bladder to muscle invasive disease and subsequent disease fatality.

MATERIALS AND METHODS

Patients with a new diagnosis of pT1G3 NXM0 transitional cell carcinoma with unifocal disease and no carcinoma in situ (group 1), or with multifocal disease and/or carcinoma in situ (group 2) were eligible for the trial. Patients in group 1 were randomized between observation and radiotherapy to the bladder, and in group 2 between intravesical therapy and radiotherapy.

RESULTS

From September 1991 to February 2003 a total of 210 patients from 37 centers in the United Kingdom were entered into the study. There were 77 patients in group 1 and 133 patients in group 2, and 6 patients were excluded from analysis because they were found to have pT2 disease by the reference pathologist. No evidence of an advantage with radiotherapy was found in terms of progression-free interval (hazard ratio 1.07; 95% CI 0.65, 1.74; p = 0.785), progression-free survival (hazard ratio 1.35; 95% CI 0.92, 1.98; p = 0.133) or overall survival (hazard ratio 1.32; 95% CI 0.86, 2.04; p = 0.193).

CONCLUSIONS

To our knowledge this is the largest randomized trial performed in patients with pT1G3 disease for which 210 patients were recruited during 11 years. There is no evidence that radiotherapy is better than more conservative treatment. The prognosis of this group of patients appears to be poor irrespective of treatment and new treatment strategies need to be investigated.
