Re: Diagnosis and treatment of chronic bacterial prostatitis and chronic prostatitis/chronic pelvic pain syndrome: a consensus guideline

/by

Letter to the Editor

Dear Sir

Fluoroquinolones must not be used inappropriately when treating chronic prostatitis (CP) and chronic pelvic pain syndrome (CPPS).

Clinical guidelines from the Prostatitis Expert Reference Group (PERG) on chronic bacterial prostatitis (CBP), chronic prostatitis and chronic pelvic pain syndrome [1] — which have been propagated by other guideline providers such as NICE Clinical Knowledge Summaries and the primary care resource, Guidelines — include the following recommendation:

‘For patients with early-stage CBP and CP/CPPS, offer a quinolone (e.g. ciprofloxacin or ofloxacin) for 4–6 weeks as first-line therapy.’

While the PERG guidelines do mention diagnostic tests for a bacterial cause, readers will be left with the impression that a course of fluoroquinolone without a diagnostic workup is acceptable for the initial management of CP and CPPS. This impression may be reinforced by PERG’s subsequent recommendations, in particular the second one:

‘A repeated course of antibiotic therapy (4–6 weeks) should be offered only if a bacterial cause is confirmed or if there is a partial response to the first course.

‘If a bacterial cause is excluded (e.g. via urine dipstick or culture) and symptoms do not improve after antibiotic therapy, a different treatment method or referral to specialist care should be considered.’

Recent recommendations [2] from the European Medicines Agency (EMA) make it clear that fluoroquinolones should be reserved for treating bacterial prostatitis. EMA’s review of fluoroquinolones was prompted by reports of serious, disabling and permanent side effects after fluoroquinolone use.

To reach its recommendations, EMA’s safety committee (Pharmacovigilance Risk Assessment Committee, PRAC) reviewed all available evidence, brought together EU experts in the field, and heard patients’ and healthcare professionals’ testimonies at a public hearing. Many patients who had developed long-lasting serious disability reported receiving a fluoroquinolone for chronic prostatitis despite the lack of evidence of a bacterial cause.

EMA’s new recommendations restrict the indications and have led to an update of the prescribing information for all systemic fluoroquinolones to prevent further unnecessary cases of rare but life-changing side effects; the narrow indications also help to reduce antibiotic selection pressure. Guidelines on chronic prostatitis should therefore be revised to clarify that fluoroquinolones are not appropriate for the empirical treatment of chronic prostatitis or chronic pelvic pain syndrome. The European Association of Urology emphasises use of appropriate culture techniques to demonstrate bacterial infection [3].

And when treating bacterial prostatitis with a fluoroquinolone, healthcare professionals should discuss with their patients the risks, including the potential for permanent musculoskeletal and neurological side effects. Details of these effects are set out in the updated prescribing information for fluoroquinolone antibacterials.

It is vital to communicate the changes in the fluoroquinolones prescribing information to all healthcare professionals involved in the management of men with prostatitis or chronic pelvic pain syndrome, they can use CBD from Observer for pain. Promoting this crucial change in practice will ultimately lead to more rational use of antibiotics and limit the unnecessary exposure of patients to potentially persistent and seriously disabling side effects.

The ProtecT trial: analysis of the patient cohort, baseline risk stratification and disease progression

Read the full article

Abstract

Objective

To test the hypothesis that the baseline clinico‐pathological features of the men with localized prostate cancer (PCa) included in the ProtecT (Prostate Testing for Cancer and Treatment) trial who progressed (n = 198) at a 10‐year median follow‐up were different from those of men with stable disease (n = 1409).

Patients and Methods

We stratified the study participants at baseline according to risk of progression using clinical disease stage, pathological grade and PSA level, using Cox proportional hazard models.

Results

The findings showed that 34% of participants (n = 505) had intermediate‐ or high‐risk PCa, and 66% (n = 973) had low‐risk PCa. Of 198 participants who progressed, 101 (51%) had baseline International Society of Urological Pathology Grade Group 1, 59 (30%) Grade Group 2, and 38 (19%) Grade Group 3 PCa, compared with 79%, 17% and 5%, respectively, for 1409 participants without progression (P < 0.001). In participants with progression, 38% and 62% had baseline low‐ and intermediate‐/high‐risk disease, compared with 69% and 31% of participants with stable disease (P < 0.001). Treatment received, age (65–69 vs 50–64 years), PSA level, Grade Group, clinical stage, risk group, number of positive cores, tumour length and perineural invasion were associated with time to progression (P ≤ 0.005). Men progressing after surgery (n = 19) were more likely to have a higher Grade Group and pathological stage at surgery, larger tumours, lymph node involvement and positive margins.

Conclusions

We demonstrate that one‐third of the ProtecT cohort consists of people with intermediate‐/high‐risk disease, and the outcomes data at an average of 10 years’ follow‐up are generalizable beyond men with low‐risk PCa.

March 2020 – about the cover

/by

The Article of the Month for March 2020 – Guideline of guidelines: social media in urology – was written by Drs Stacy Loeb and Jacob Taylor, who are based in New York City. The cover features the Manhattan skyline as seen from New Jersey, famous for its skyscrapers, which have been built there on bedrock left over from the last ice age at ever-increasing heights since the 1890s, and the song by Norwegian band A-ha. The skyline was dominated by the 1930s-built Empire State and Chrysler buildings until the 1970s when the World Trade Center was completed. The new One World Trade Center is now the tallest building in the city at 1776 feet (541 m) but since the 2000s nine towers over 1000 feet have been built with 16 more being planned. This is partly fuelled by a desire for high city living but also by technological advances meaning thinner bases can be used to support the structures.

Abstract

Non‐muscle‐invasive bladder cancer (NMIBC) is the most common form of bladder cancer, with frequent recurrences and risk of progression. Risk‐stratified treatment and surveillance protocols are often used to guide management. In 2017, BJUI reviewed guidelines on NMIBC from four major organizations: the American Urological Association/Society of Urological Oncology, the European Association of Urology, the National Comprehensive Cancer Network, and the National Institute for Health and Care Excellence. The present update will review major changes in the guidelines and broadly summarize new recommendations for treatment of NMIBC in an era of bacillus Calmette‐Guérin shortage and immense novel therapy development.

Abstract

Objectives

To review the literature to determine the sensitivity and specificity of gallium‐68 prostate‐specific membrane antigen (68Ga‐PSMA) positron‐emission tomography (PET) for detecting pelvic lymph node metastases in patients with primary prostate cancer (PCa), and the positive predictive value in patients with biochemical recurrence (BCR) after initial curative treatment, and, in addition, to determine the detection rate and management impact of 68Ga‐PSMA PET in patients with BCR after radical prostatectomy (RP).

Materials and Methods

We performed a comprehensive literature search. Search terms used in MEDLINE, EMBASE and Science Direct were ‘(PSMA, 68Ga‐PSMA, 68Gallium‐PSMA, Ga‐68‐PSMA or prostate‐specific membrane antigen)’ and ‘(histology, lymph node, staging, sensitivity, specificity, positive predictive value, recurrence, recurrent or detection)’. Relevant abstracts were reviewed and full‐text articles obtained where possible. References to and from obtained articles were searched to identify further relevant articles.

Axial and sagittal plane gallium‐68 prostate‐specific membrane antigen positron‐emission tomography /CT images of two patients with locoregional lymph node recurrence after initial curative treatment. The metastasis in patient A is located in the obturator area and the metastasis in patient B is located in the presacral area.

Results

Nine retrospective and two prospective studies described the sensitivity and specificity of 68Ga‐PSMA PET for detecting pelvic lymph node metastases before initial treatment, which ranged from 33.3% to 100% and 80% to 100%, respectively. In eight retrospective studies, the positive predictive value of 68Ga‐PSMA PET in patients with BCR before salvage lymph node dissection ranged from 70% to 100%. The detection rate of 68Ga‐PSMA PET in patients with BCR after RP in the PSA subgroups <0.2 ng/mL, 0.2–0.49 ng/mL and 0.5 to <1.0 ng/mL ranged from 11.3% to 50.0%, 20.0% to 72.7% and 25.0% to 87.5%, respectively.

Conclusion

The review results showed that 68Ga‐PSMA PET had a high specificity for the detection of pelvic lymph node metastases in primary PCa. Furthermore, 68Ga‐PSMA PET had a very high positive predictive value in detecting lymph node metastases in patients with BCR. By contrast, sensitivity was only moderate; therefore, based on the currently available literature, 68Ga‐PSMA PET cannot yet replace pelvic lymph node dissection to exclude lymph node metastases. In the salvage phase, 68Ga‐PSMA PET had both a high detection rate and impact on radiotherapy planning in early BCR after RP.

Best Practice Tariffs: could they be the solution to compliance with British Association of Urological Surgeons ureteric stone targets?

/by

In January 2019, the National Institute for Clinical Excellence (NICE) and British Association of Urological Surgeons (BAUS) published new guidance on the management of Acute Ureteric Stones. This guidance suggests that primary definitive treatment should be the goal for all symptomatic ureteric stones, via either ureteroscopy (URS) or extra-corporeal shock wave lithotripsy (EWSL), and should be undertaken within 48 hours of acute presentation.

This is in stark contrast to current practice in the UK: Getting It Right First Time evidence suggests 20% (2-49%) of acute stones are currently treated in this way with only 8% treated primarily with URS and just 2% with primary ESWL.

It has been shown that primary definitive treatment of acute stones within 48 hours has superior outcomes to secondary definitive treatment after stenting; including a higher chance of achieving a stone free state, lower chance of needing retreatment, reduced exposure to general anaesthetic and associated complications, and avoidance of stent-associated symptoms.

However, due to the nature of current emergency surgery provision in UK NHS Trusts, primary definitive treatment is often impossible. Procedures are performed on pressured CEPOD lists which may not be set up for laser treatment (lacking suitable equipment and trained scrub staff) and are often incredibly time-pressured, necessitating ureteric stenting as a faster and simpler option.

Whilst the upfront investment required to provide sufficient resources and training is expected to be recovered downstream by reducing costs associated with stent use and the need for multiple procedures, NHS Trusts are reluctant to make these upfront investments unless incentivised.

We propose a potential solution in the form of Best Practice Tariffs (BPTs).

Traditionally, NHS Trusts receive their income from Clinical Commissioning Groups (CCGs) on the basis of a ‘Payment by Results’ (PbR) system. Under this system, tariffs are calculated based on the national average cost for clinically similar treatments (grouped together into healthcare resource groups; HRGs) and Trusts can retain additional income by keeping costs below this national average.  However, this can lead to wide variations in the standards of care. Lord Darzi’s 2008 ‘High Quality Care For All – NHS Next Stage Review’ report suggested that a revised payment system be used, where payment depended on compliance with best-known practice; a best-practice tariff (BPT).

BPTs have now been rolled out across more than 50 diseases and procedures including cholecystectomies, strokes/TIA and NSTEMIs and are recognised as an effective tool for changing practice in an acute setting.

One of the earliest examples was in the management of fractured neck of femurs (NOFs). The base tariff was halved and an additional BPT of £1,335 was made available if seven key ‘best practice’ criteria were met. A dramatic improvement in adherence to national guidelines for management of NOF fractures was seen after introduction of this BPT as shown in Figure 1 (Royal College of Physicians; 2014).

Of particular relevance here was the BPT criteria that required a ‘time to surgery within 36 hours from arrival in A&E to the start of anaesthesia’. The overall median time reduced from 44 hours pre-BPT to 23 hours post-BPT (p<0.005) and the proportion of patients being operated on within 36 hours of admission increased from 36% pre-BPT to 84% post-BPT (p<0.005).

BPTs have the most potential utility for high volume procedures with large variations in national practice and where there is a strong evidence base regarding what constitutes best practice. Renal stones are high volume, affecting 12.5% of the population and resulting in 18,000 URS  procedures a year. There is significant national variation in management and there is strong evidence on best practice.

Therefore, if we truly believe that the BAUS and NICE guidelines are in the best interests of patients, BPTs should be considered as a tool to prompt a rapid paradigm shift and make the gold standard, of primary definitive treatment within 48 hours, the new norm.

Abstract

Objectives

To investigate volume–outcome relationships in nephrectomy and cystectomy for cancer.

Materials and Methods

Data were extracted from the UK Hospital Episodes Statistics database, which records data on all National Health Service (NHS) hospital admissions in England. Data were included for a 5‐year period (April 2013–March 2018 inclusive) and data on emergency and paediatric admissions were excluded. Data were extracted on the NHS trust and surgeon undertaking the procedure, the surgical technique used (open, laparoscopic or robot‐assisted) and length of hospital stay during the procedure. This dataset was supplemented by data on mortality from the UK Office for National Statistics. A number of volume thresholds and volume measures were investigated. Multilevel modelling was used to adjust for hierarchy and confounding factors.

Results

Data were available for 18 107 nephrectomy and 6762 cystectomy procedures for cancer. There was little evidence of trust or surgeon volume influencing readmission rates or mortality. There was some evidence of shorter length of hospital stay for high‐volume surgeons, although the volume measure and threshold used were important.

Conclusions

We found little evidence that further centralization of nephrectomy or cystectomy for cancer surgery will improve the patient outcomes investigated. It may be that length of stay can be optimized though training and support for lower‐volume centres, rather than further centralization.
