RESUMEN

Objectives: To test the feasibility of a randomised controlled trial (RCT) of aspirin and/or vitamin D3 in active surveillance (AS) low/favourable intermediate risk prostate cancer (PCa) patients with Prolaris® testing. Patients and Methods: Newly-diagnosed low/favourable intermediate risk PCa patients (PSA ≤ 15 ng/ml, International Society of Urological Pathology (ISUP) Grade Group ≤2, maximum biopsy core length <10 mm, clinical stage ≤cT2c) were recruited into a multi-centre randomised, double-blind, placebo-controlled study (ISRCTN91422391, NCT03103152). Participants were randomised to oral low dose (100 mg), standard dose (300 mg) aspirin or placebo and/or vitamin D3 (4000 IU) versus placebo in a 3 × 2 factorial RCT design with biopsy tissue Prolaris® testing. The primary endpoint was trial acceptance/entry rates. Secondary endpoints included feasibility of Prolaris® testing, 12-month disease re-assessment (imaging/biochemical/histological), and 12-month treatment adherence/safety. Disease progression was defined as any of the following (i) 50% increase in baseline PSA, (ii) new Prostate Imaging-Reporting and Data System (PI-RADS) 4/5 lesion(s) on multi-parametric MRI where no previous lesion, (iii) 33% volume increase in lesion size, or radiological upstaging to ≥T3, (iv) ISUP Grade Group upgrade or (v) 50% increase in maximum cancer core length. Results: Of 130 eligible patients, 104 (80%) accepted recruitment from seven sites over 12 months, of which 94 patients represented the per protocol population receiving treatment. Prolaris® testing was performed on 76/94 (81%) diagnostic biopsies. Twelve-month disease progression rate was 43.3%. Assessable 12-month treatment adherence in non-progressing patients to aspirin and vitamin D across all treatment arms was 91%. Two drug-attributable serious adverse events in 1 patient allocated to aspirin were identified. The study was not designed to determine differences between treatment arms. Conclusion: Recruitment of AS PCa patients into a multi-centre multi-arm placebo-controlled RCT of minimally-toxic adjunctive oral drug treatments with molecular biomarker profiling is acceptable and safe. A larger phase III study is needed to determine optimal agents, intervention efficacy, and outcome-associated biomarkers.

RESUMEN

Urologic patients receiving bone-targeted therapies are at risk of developing osteonecrosis of the jaw (ONJ). ONJ has historically been associated with bisphosphonate therapy. More recently, RANK-Ligand inhibitors (denosumab) have also been used to reduce the risk of skeletal-related events in patients who have advanced cancers with bone metastases. More than 65% of men with metastatic prostate cancer and nearly 75% of women with metastatic breast cancer are affected by bone metastases. The literature has described ONJ associated with bisphosphonate therapy as bisphosphonate-related osteonecrosis of the jaw (BRONJ). However, with evidence also linking the use of RANK-Ligand inhibitors with osteonecrosis of the jaw, we advocate use of the term "anti-bone resorption therapy-related osteonecrosis of the jaw" (ABRT-ONJ). The term "medication-related osteonecrosis of the jaw" (MRONJ) is now becoming more widespread. There is not a universally accepted definition of ABRT-ONJ, which may have hindered recognition and reporting of the condition. In Part I of this article, a review of current knowledge around the etiology of ABRT-ONJ and incidence data are provided. In Part II, we provide an audit of ONJ in a nurse consultant-led bone support clinic. In the article, we refer to zoledronic acid because this is the bisphosphonate of choice for use in men with prostate cancer in the United Kingdom.

RESUMEN

Men who receive bone-targeted therapy for metastatic prostate cancer are at increased risk of osteonecrosis of the jaw (ONJ). Development of ONJ has been associated with the administration of bone-targeted therapies in association with other risk factors. ONJ can be distressing for a patient because it can cause pain, risk of jaw fracture, body image disturbance, difficultly eating, and difficulty maintaining good oral hygiene. The aim of this article is to report results of an audit of prior assessment by oral and maxillofacial surgeons (OMFS) before initiation of bone-targeted therapies and whether it may reduce the risk of ONJ in patients receiving bone-targeted therapies for advanced cancers.

RESUMEN

Part 1 of this article highlighted the potential negative effects of cancer on the skeleton and provided an overview of available treatment options. Part 2 presents a nurse practitioner-led Bone Support Clinic, which was developed for patients with cancer-induced bone disease and cancer therapy-induced bone loss. This clinic, started in 2011 in a university medical center urology/oncology outpatient center in London, England, United Kingdom, has been a collaborative effort among a multidisciplinary team of doctors, nurse practitioners and nurses. Patients have responded positively to the improved continuity of care, and we have been able to assess and treat impending skeletal-related events in a more timely manner The needs of our patient population and problems with the existing service are reviewed, and the importance of a multidisciplinary approach to these problems is discussed. Initiation of a nurse practitioner-led Bone Support Clinic and the impact of timely response to the effects of cancer and cancer therapies on the skeletal system are outlined and offered as a model.

RESUMEN

Cancer-induced bone disease and cancer therapy-induced bone loss are significant skeletal problems related to the treatment for urological and other cancers. Our team of specialists and nurse practitioners developed a nurse practitioner-led Bone Support Clinic for urologic cancer patients at a university hospital in London, England, United Kingdom, to address this issue. The clinic has been well-accepted, has made a positive impact on the patient journey, helps to ensure continuity of care, and highlights patients who require assessment or treatment for impending skeletal-related events in a timely fashion. This article has been divided into two parts for improved readability.

RESUMEN

Transrectal ultrasound guided biopsy of the prostate remains the gold standard investigation to diagnose prostate cancer. Although post-biopsy complications are relatively rare, the risk of sepsis associated with the procedure means that prophylactic antibiotics are paramount. The most widely used antibiotic regimen includes a quinolone, such as ciprofloxacin. Resistance to quinolone antibiotics is rising. In this small pilot study, the incidence of quinolone resistance was 18% in our population of patients attending the prostate biopsy clinic.

RESUMEN

AIMS: To determine the use of antibiotics in patients with renal colic and an elevated white cell count (WCC) in the absence of other features of infection. MATERIALS AND METHODS: A retrospective audit of patients presenting to an emergency department with renal colic caused by a solitary ureteric stone over a 6 month period. STATISTICAL ANALYSIS USED: Student's t-test. RESULTS: Fifty patients met the inclusion criteria for this study. In 42 patients (84%) the urinalysis showed hematuria only and all urine culture results were negative for microbial growth. The mean WCC was 11.5 × 10(9) (4-22.1) and was raised in 34 patients (80.9%). The mean neutrophil count was 8.75 × 10(9)/L (2.3-18.6) and C-reactive protein (CRP) 15.9 (1-192). Antibiotics were commenced in 34 patients (80.9%) based solely on the raised WCC. In eight patients (16%) there were leucocytes and/or nitrites on urinalysis and all urine cultures were positive for growth (coliforms in five, streptococcus in two and candida in one specimen). The mean WCC was 10.5 × 10(9)/L (7.7-16.5) and was raised in four patients. The mean neutrophil count was 8.4 × 10(9)/L (4.9-15.2) and CRP 40.79 (3-86). One patient had pyrexia. All eight patients were commenced on antibiotics based on the WCC and/or urinalysis result. CONCLUSIONS: Over three-quarters of the patients (80.9%) in this study who presented with renal colic were unjustifiably commenced on antibiotics based solely on an elevated WCC. Antibiotic use in renal colic should be reserved for when there are features of sepsis or the urinalysis is positive. Further work is required to determine the significance of the observed results and the threshold for starting antibiotics.

RESUMEN

Chronic cystitis associated with ketamine use is a growing problem among a young patient population who use the drug recreationally. Patients may present with symptoms such as urinary frequency, dysuria, urgency and haematuria in accident and emergency departments, GP surgeries, urology outpatient departments, drug rehabilitation or substance misuse units, genitourinary medicine clinics or continence services. Nurses in these areas therefore need to be aware of the symptoms associated with ketamine-associated bladder damage and be prepared to ask patients about recreational drug use and inform them of possible treatments. This case report illustrates one patient's successful response to treatment with chondroitin sulphate 0.2% (Gepan) over a 1-year period.

RESUMEN

INTRODUCTION: Benign prostatic hyperplasia (BPH) and cataract formation are common in older people. Medical management of symptomatic BPH is often preferred to surgical treatment as surgery increases the risk of morbidities, whereas, surgery is the main form of treatment to restore sight in patient with cataract. The clinical treatment of BPH is either alpha-1 adrenergic antagonist alone or combination of alpha reductase inhibitor and alpha adrenergic receptor (AR) antagonist. There are four alpha-AR antagonists currently available to treat BPH. The uroselective alpha-blocker tamsulosin is the most commonly used drug among all. Studies showed that the majority of the patients who develop intraoperative floppy iris syndrome (IFIS) were on tamsulosin. Women are more likely to develop cataract than men and some recent studies showed that tamsulosin is effective in treating female lower urinary tract symptoms and thereby can cause IFIS during cataract surgery. EVIDENCE ACQUISITION: We performed a critical review of the published articles and abstracts on association of IFIS with alpha-blockers and other medications as well as other medical conditions. EVIDENCE SYNTHESIS: Tamsulosin is the most common cause of formation of IFIS. However, not all patients given tamsulosin develop IFIS and cases have been reported without any tamsulosin treatment. CONCLUSION: Tamsulosin is a recognized cause to impede mydriasis and lead to IFIS during cataract surgery. Urologist should collaborate with their ophthalmology colleagues and general practitioner during prescribing tamsulosin in patients with history of cataract or waiting for planned cataract surgery. The increasing life expectancy and growth of older people will increase the number of men and women who suffer from lower urinary tract symptoms as well as cataract. Therefore, further research and studies are required to properly understand the relation of alpha blockers and IFIS.

RESUMEN

PURPOSE: We aimed to assess the influence of trait emotional intelligence (trait EI) and perceived social support on psychological impairment in a sample of patients urgently referred for prostate and bladder cancer investigations. METHODS: Eighty seven patients (mean age = 62.92; SD = 13.23) were recruited prior to undergoing an investigative procedure for either prostate (n = 45) or bladder (n = 42) cancer. Patients completed measures of psychological impairment (state anxiety and worry) and 82 also competed measures of trait EI and perceived social support. Multivariate linear regression was used to predict the direct and moderated effects of trait EI and perceived social support on psychological impairment. RESULTS: Thirty one percent of patients were considered to be suffering from clinical levels of state anxiety. Trait EI was a significant predictor of state anxiety, worry regarding the appointment, worry regarding the outcome of the appointment and perceived social support. In contrast, perceived social support was not predictive of psychological impairment on any measure and did not moderate the relationship between trait EI and psychological impairment. CONCLUSIONS: Patients urgently referred for urological cancer investigations are a group at risk of psychological impairment and may benefit from healthcare professional support. High trait EI was associated with less state anxiety, less worry and higher perceived social support. There were few consistent effects of perceived social support on psychological impairment. Consideration should be given to the inclusion of trait EI in future models of trauma adaptation.

RESUMEN

INTRODUCTION: We report the case of a true hermaphrodite with testicular seminoma with resulting metastases to the inguinal lymph nodes eight months after radical orchidectomy. This is an unusual presentation of testicular cancer and, to the best of our knowledge, the first report of this kind in the literature. CASE PRESENTATION: A 45-year-old Caucasian true hermaphrodite, raised as a male, developed a testicular seminoma. He had undergone a left orchidopexy at the age of 10 for undescended testes. Metastases from testicular tumors to inguinal lymph nodes are a rare occurrence. It has been suggested that previous inguinal or scrotal surgery may alter the pattern of nodal metastasis of testicular cancer. We review the literature to evaluate the incidence of inguinal lymph node involvement in early stage testicular cancer and discuss possible routes of metastases to this unusual site. We also discuss the management of the inguinal lymph nodes in patients with testicular tumors and a previous history of inguinal or scrotal surgery, as this remains controversial. CONCLUSION: Inguinal lymph node metastases from testicular cancer are rare. A history of inguinal or scrotal surgery may predispose involvement of the inguinal nodes. During radical inguinal orchidectomy, the surgeon should be careful to minimize the handling of the testis and ensure high ligation of the spermatic cord up to the internal inguinal ring to reduce the risk of inguinal lymph node metastasis.

RESUMEN

OBJECTIVE: To determine the incidence and treatment of lymphoceles after retropubic radical prostatectomy (RP). PATIENTS AND METHODS: Up to January 2004, 260 patients who had a retropubic RP in one institution by one surgeon were assessed retrospectively, using the patients' notes or the computerized results system to determine whether a lymphocele was suspected and then confirmed by imaging studies (computed tomography or ultrasonography). RESULTS: Nine patients developed symptomatic lymphoceles; eight of these were detected by imaging. Four lymphoceles required intervention while the remainder regressed spontaneously. No complications were reported in the group that was treated. CONCLUSION: The rate of symptomatic lymphocele formation was low after RP, with an overall incidence of 3.5%. Ultrasonography was effective in detecting lymphoceles and ultrasonographically guided percutaneous drainage an effective treatment.
