RESUMO
INTRODUCTION: Radical cystectomy remains the standard treatment for intravesical Bacille Calmette-Guerin (BCG) unresponsive non-muscle invasive bladder cancer (NMIBC) because potential bladder-preserving therapies are not well established. Combination of radiotherapy with programmed death-1 (PD-1) antibody may offer an optional bladder preservation treatment for high-risk/extremely high risk NMIBC. Hence, the current study aims to investigate the safety and efficacy of short-course radiotherapy (5×5 Gy) and toripalimab (PD-1 antibody) as a novel bladder sparing treatment in this population. METHODS AND ANALYSIS: HOPE-04 is an open-label, single-arm, phase II study, designed to evaluate the safety and efficacy of short-course radiotherapy and toripalimab in patients with high-risk/extremely high risk NMIBC. Fifty-five patients with pathological and imaging diagnosed NMIBC with or without BCG treatment will be recruited. Radiotherapy of 5×5 Gy will be given to the whole bladder followed by a focal tumour bed boost and concomitant administration of toripalimab of 240 mg intravenous infusion every 21 days for 12 cycles (about 1 year). The primary endpoints are disease-free survival and safety. The secondary endpoint is overall survival. Additional indicators include implementation rate of salvage surgery and quality of life. ETHICS AND DISSEMINATION: This trial has been approved by the Ethics Committee of West China Hospital, Sichuan University. Trial findings will be disseminated via peer reviewed journals and conference presentations. TRIAL REGISTRATION NUMBER: Chinese Ethics Committee of Registering Clinical Trials (ChiCTR2200059970).

INTRODUCTION: Despite radical prostatectomy (RP) and radiotherapy (RT) being established treatments for localised prostate cancer, a significant number of patients experience recurrent disease. While conventionally fractionated RT is still being used as a standard treatment in the postoperative setting, ultra-hypofractionated RT has emerged as a viable option with encouraging results in patients with localised disease in the primary setting. In addition, recent technological advancements in RT delivery and precise definition of isolated macroscopic recurrence within the prostate bed using prostate-specific membrane antigen-positron emission tomography (PSMA-PET) and multiparametric MRI (mpMRI) allow the exploration of ultra-hypofractionated schedules in the salvage setting using five fractions. METHODS AND ANALYSIS: In this single-arm prospective phase II multicentre trial, 36 patients with node-negative prostate adenocarcinoma treated with RP at least 6 months before trial registration, tumour stage pT2a-3b, R0-1, pN0 or cN0 according to the UICC TNM 2009 and evidence of measurable local recurrence within the prostate bed detected by PSMA PET/CT and mpMRI within the last 3 months, will be included. The patients will undergo focal ultra-hypofractionated salvage RT with 34 Gy in five fractions every other day to the site of local recurrence in combination with 6 months of androgen deprivation therapy. The primary outcome of this study is biochemical relapse-free survival at 2 years. Secondary outcomes include acute side effects (until 90 days after the end of RT) of grade 3 or higher based on Common Terminology Criteria for Adverse Events V.5, progression-free survival, metastasis-free survival, late side effects and the quality of life (based on European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-C30, QLQ-PR25). ETHICS AND DISSEMINATION: The study has received ethical approval from the Ethics Commission of the Canton of Bern (KEK-BE 2022-01026). Academic dissemination will occur through publications and conference presentations. TRIAL REGISTRATION NUMBER: NCT05746806.

INTRODUCTION: There are notable disparities in health-related quality of life (HRQOL) between gay and bisexual men (GBM) and heterosexual patients with prostate cancer (PCa); however, the role of past military service is unclear. This study examines HRQOL differences in GBM PCa survivors based on reported military service history. METHODS: We used data from the 24-month follow-up survey of the Restore-2 study, a clinical trial which evaluated a rehabilitation programme for GBM PCa survivors. PCa HRQOL was assessed using the Expanded Prostate Cancer Index Composite (EPIC-50) and the Functional Assessment of Cancer Treatment-Prostate (FACT-P). Mental health quality of life was assessed using the Brief Symptom Inventory-18 (BSI-18) scale, while sexual functioning was measured using the Sexual Minorities and Prostate Cancer Scale (SMACS). Multivariable linear regression was used to estimate unadjusted and adjusted mean differences in HRQOL between GBM with and without a reported history of military service. RESULTS: In this cross-sectional study of 351 GBM PCa survivors, 47 (13.4%) reported a history of US military service. After adjusting for covariates, participants who reported a history of military service (compared with those with no military service) had clinically better scores on the FACT-P physical, social and emotional well-being domains, as well as higher total FACT-General, EPIC urinary bother and hormonal function scores. Additionally, men with a history of military service reported significantly fewer sexual problems, more sexual confidence and less urinary incontinence in sex. CONCLUSION: This exploratory study provides the first evidence that GBM PCa survivors with a military background may have clinically better outcomes than those without military service. Potential reasons may include the structured support and healthcare access associated with military service, fostering resilience and well-being. These findings underscore the need for further research to elucidate how military service influences PCa HRQOL.
RESUMO
OBJECTIVES: This study aims to present the clinical characteristics of young patients with bladder cancer (YBCa), evaluate related risk factors and construct a nomogram based on data acquired from the Surveillance, Epidemiology, and End Results (SEER) Database. DESIGN: Retrospective analysis of the SEER Database (2004-2015) for primary YBCa. SETTING AND PARTICIPANTS: Data for YBCa (defined as those aged 40 years or younger) were extracted from the SEER Database, which covers approximately 28% of the US population, using the SEER*Stat software (V.8.4.0.1). A total of 1233 YBCa were identified. Patients were randomly assigned to the training and validation sets. The database included clinicopathological features, demographic information and survival outcomes, such as age, gender, race, year of diagnosis, marital status at diagnosis, primary tumour site, histological type, tumour grade, tumour, node, metastases (TNM) staging, treatment regimen for the primary tumour, cause of death and survival time. A nomogram model was developed using univariate and multivariate analyses. The prediction model was validated using the consistency index (C-index), calibration curve and receiver operating characteristic curve. PRIMARY OUTCOME MEASURES: 3-year, 5-year and 10-year overall survival (OS). RESULTS: 1233 YBCa from 2004 to 2015 were randomly assigned to the training set (n=865) and validation set (n=368). Age, marital status, tumour grade, histological type and TNM staging were included in the nomogram. The C-index of the model was 0.876. The 3-year, 5-year and 10-year OS area under the curve values for the training and validation sets were 0.949, 0.923 and 0.856, and 0.919, 0.890 and 0.904, respectively. Calibration plots showed that the nomogram had a robust predictive accuracy. CONCLUSIONS: To our knowledge, this is the first study to establish a precise nomogram predicting the 3-year, 5-year and 10-year OS in YBCa based on multivariate analyses. Our nomogram may serve as a valuable reference for future diagnostics and individualised treatments for YBCa. However, external validation is warranted to assess the accuracy and generalisability of our prognostic model.

OBJECTIVES: Immune checkpoint inhibitors (ICIs) are indicated for metastatic urothelial cancer (mUC), but predictive and prognostic factors are lacking. We investigated clinical variables associated with ICI outcomes. METHODS: We performed a multicentre retrospective cohort study of 135 patients who received ICI for mUC, 2016-2021, at three Canadian centres. Clinical characteristics, body mass index (BMI), metastatic sites, neutrophil-to-lymphocyte ratio (NLR), response and survival were abstracted from chart review. RESULTS: We identified 135 patients and 62% had received ICI as a second-line or later treatment for mUC. A BMI ≥25 was significantly correlated to a higher overall response rate (ORR) (45.4% vs 16.3%, p value=0.020). Patients with BMI ≥30 experienced longer median overall survival (OS) of 24.8 vs 14.4 for 25≤BMI<30 and 8.5 months for BMI <25 (p value=0.012). The ORR was lower in the presence of bone metastases (16% vs 41%, p value=0.006) and liver metastases (16% vs 39%, p value=0.013). Metastatic lymph nodes were correlated with higher ORR (40% vs 20%, p value=0.032). The median OS for bone metastases was 7.3 versus 18 months (p value <0.001). Patients with liver metastases had a median OS of 8.6 versus 15 months (p value=0.006). No difference for lymph nodes metastases (13.5 vs 12.7 months, p value=0.175) was found. NLR ≥4 had worse OS (8.2 vs 17.7 months, p value=0.0001). In multivariate analysis, BMI ≥30, bone metastases, NLR ≥4, performance status ≥2 and line of ICI ≥2 were independent factors for OS. CONCLUSIONS: Our data identified BMI and bone metastases as novel clinical biomarkers that were independently associated with ICI outcomes in mUC. External and prospective validation are warranted.

INTRODUCTION: Transurethral resection of bladder tumour (TURBT) is one of the more common procedures performed by urologists. It is often described as an 'incision-free' and 'well-tolerated' operation. However, many patients experience distress and discomfort with the procedure. Substantial opportunity exists to improve the TURBT experience. An enhanced recovery after surgery (ERAS) protocol designed by patients with bladder cancer and their providers has been developed. METHODS AND ANALYSIS: This is a single-centre, randomised controlled trial to investigate the effectiveness of an ERAS protocol compared with usual care in patients with bladder cancer undergoing ambulatory TURBT. The ERAS protocol is composed of preoperative, intraoperative and postoperative components designed to optimise each phase of perioperative care. 100 patients with suspected or known bladder cancer aged ≥18 years undergoing initial or repeat ambulatory TURBT will be enrolled. The change in Quality of Recovery 15 score, a measure of the quality of recovery, between the day of surgery and postoperative day 1 will be compared between the ERAS and control groups. ETHICS AND DISSEMINATION: The trial has been approved by the Johns Hopkins Institutional Review Board #00392063. Participants will provide informed consent to participate before taking part in the study. Results will be reported in a separate publication. TRIAL REGISTRATION NUMBER: NCT05905276.

INTRODUCTION: The empty pelvis syndrome is a significant source of morbidity following pelvic exenteration surgery. It remains poorly defined with research in this field being heterogeneous and of low quality. Furthermore, there has been minimal engagement with patient representatives following pelvic exenteration with respect to the empty pelvic syndrome. 'PelvEx-Beating the empty pelvis syndrome' aims to engage both patient representatives and healthcare professionals to achieve an international consensus on a core outcome set, pathophysiology and mitigation of the empty pelvis syndrome. METHODS AND ANALYSIS: A modified-Delphi approach will be followed with a three-stage study design. First, statements will be longlisted using a recent systematic review, healthcare professional event, patient and public engagement, and Delphi piloting. Second, statements will be shortlisted using up to three rounds of online modified Delphi. Third, statements will be confirmed and instruments for measurable statements selected using a virtual patient-representative consensus meeting, and finally a face-to-face healthcare professional consensus meeting. ETHICS AND DISSEMINATION: The University of Southampton Faculty of Medicine ethics committee has approved this protocol, which is registered as a study with the Core Outcome Measures in Effectiveness Trials Initiative. Publication of this study will increase the potential for comparative research to further understanding and prevent the empty pelvis syndrome. TRIAL REGISTRATION NUMBER: NCT05683795.

PURPOSE: Bladder cancer is a complex disease with a wide range of outcomes. Clinicopathological factors only partially explain the variability between patients in prognosis and treatment response. There is a need for large cohorts collecting extensive data and biological samples to: (1) investigate gene-environment interactions, pathological/molecular classification and biomarker discovery; and (2) describe treatment patterns, outcomes, resource use and quality of life in a real-world setting. PARTICIPANTS: COBLAnCE (COhort to study BLAdder CancEr) is a French national prospective cohort of patients with bladder cancer recruited between 2012 and 2018 and followed for 6 years. Data on patient and tumour characteristics, treatments, outcomes and biological samples are collected at enrolment and during the follow-up. FINDINGS TO DATE: We describe the cohort at enrolment according to baseline surgery and tumour type. In total, 1800 patients were included: 1114 patients with non-muscle-invasive bladder cancer (NMIBC) and 76 patients with muscle-invasive bladder cancer (MIBC) had transurethral resection of a bladder tumour without cystectomy, and 610 patients with NMIBC or MIBC underwent cystectomy. Most patients had a solitary lesion (56.3%) without basement membrane invasion (71.7% of Ta and/or Tis). Half of the patients with cystectomy were stage ≤T2 and 60% had non-continent diversion. Surgery included local (n=298) or super-extended lymph node dissections (n=11) and prostate removal (n=492). Among women, 16.5% underwent cystectomy and 81.4% anterior pelvectomy. FUTURE PLANS: COBLAnCE will be used for long-term studies of bladder cancer with focus on clinicopathological factors and molecular markers. It will lead to a much-needed improvement in the understanding of the disease. The cohort provides valuable real-world data, enabling researchers to study various research questions, assess routine medical practices and guide medical decision-making.

INTRODUCTION: The incidence of renal tumours is increasing and anatomic imaging cannot reliably distinguish benign tumours from renal cell carcinoma. Up to 30% of renal tumours are benign, with oncocytomas the most common type. Biopsy has not been routinely adopted in many centres due to concerns surrounding non-diagnostic rate, bleeding and tumour seeding. As a result, benign masses are often unnecessarily surgically resected. 99mTc-sestamibi SPECT/CT has shown high diagnostic accuracy for benign renal oncocytomas and other oncocytic renal neoplasms of low malignant potential in single-centre studies. The primary aim of MULTI-MIBI is to assess feasibility of a multicentre study of 99mTc-sestamibi SPECT/CT against a reference standard of histopathology from surgical resection or biopsy. Secondary aims of the study include obtaining estimates of 99mTc-sestamibi SPECT/CT sensitivity and specificity and to inform the design and conduct of a future definitive trial. METHODS AND ANALYSIS: A feasibility prospective multicentre study of participants with indeterminate, clinical T1 renal tumours to undergo 99mTc-sestamibi SPECT/CT (index test) compared with histopathology from biopsy or surgical resection (reference test). Interpretation of the index and reference tests will be blinded to the results of the other. Recruitment rate as well as estimates of sensitivity, specificity, positive and negative predictive value will be reported. Semistructured interviews with patients and clinicians will provide qualitative data to inform onward trial design and delivery. Training materials for 99mTc-sestamibi SPECT/CT interpretation will be developed, assessed and optimised. Early health economic modelling using a decision analytic approach for different diagnostic strategies will be performed to understand the potential cost-effectiveness of 99mTc-sestamibi SPECT/CT. ETHICS AND DISSEMINATION: Ethical approval has been granted (UK HRA REC 20/YH/0279) protocol V.5.0 dated 21/6/2022. Study outputs will be presented and published nationally and internationally. TRIAL REGISTRATION NUMBER: ISRCTN12572202.

INTRODUCTION: Around 25% of patients with bladder cancer (BCa) present with invasive disease. Non-randomised studies of population-based screening have suggested reductions in BCa-specific mortality are possible through earlier detection. The low prevalence of lethal disease in the general population means screening is not cost-effective and there is no consensus on the best strategy. Yorkshire has some of the highest mortality rates from BCa in England. We aim to test whether population screening in a region of high mortality risk will lead to a downward stage-migration of aggressive BCa, improved survival and is cost-effective. METHODS AND ANALYSIS: YORKSURe is a tiered, randomised, multicohort study to test the feasibility of a large BCa screening randomised controlled trial. In three parallel cohorts, participants will self-test urine (at home) up to six times. Results are submitted via a mobile app or freephone. Those with a positive result will be invited for further investigation at community-based early detection clinics or within usual National Health Service (NHS) pathways. In Cohort 1, we will post self-testing kits to research engaged participants (n=2000) embedded within the Yorkshire Lung Screening Trial. In Cohort 2, we will post self-testing kits to 3000 invitees. Cohort 2 participants will be randomised between haematuria and glycosuria testing using a reveal/conceal design. In Cohort 3, we will post self-testing kits to 500 patients within the NHS pathway for investigation of haematuria. Our primary outcomes are rates of recruitment and randomisation, rates of positive test and acceptability of the design. The study is currently recruiting and scheduled to finish in June 2023. ETHICS AND DISSEMINATION: The study has received the following approvals: London Riverside Research Ethics Committee (22/LO/0018) and Health Research Authority Confidentiality Advisory Group (20/CAG/0009). Results will be made available to providers and researchers via publicly accessible scientific journals. TRIAL REGISTRATION NUMBER: ISRCTN34273159.

OBJECTIVES: We assessed how often National Health Service (NHS) hospitals reported that they had specific supportive services for patients with prostate cancer available onsite, including nursing support, sexual function and urinary continence services, psychological and genetic counselling, and oncogeriatric services. We identified groups of hospitals with similar patterns of supportive services. DESIGN/SETTING: We conducted an organisational survey in 2021 of all NHS hospitals providing prostate cancer services in England and Wales. Latent class analysis grouped hospitals with similar patterns of supportive services. RESULTS: In 138 hospitals, an advanced prostate cancer nurse was available in 125 hospitals (90.6%), 107 (77.5%) had a clinical nurse specialist (CNS) attending all clinics, 103 (75.7%) had sexual function services, 111 (81.6%) had continence services and 93 (69.4%) psychological counselling. The availability of genetic counselling (41 hospitals, 30.6%) and oncogeriatric services (15 hospitals, 11.0%) was lower. The hospitals could be divided into three groups. The first and largest group of 85 hospitals provided the most comprehensive supportive services onsite: all hospitals had a CNS attending all clinics, 84 (98.8%) sexual function services and 73 (85.9%) continence services. A key characteristic of the second group of 31 hospitals was that none had a CNS attending all clinics. A key characteristic of the third group of 22 hospitals was that none had sexual function services available. The hospitals in the largest group were more likely to run joint clinics (p<0.001) and host the regional specialist multidisciplinary team (p=0.002). CONCLUSIONS: There is considerable variation in supportive services for prostate cancer available onsite in NHS hospitals in England and Wales. Availability of genetic counselling and oncogeriatric services is low. The different patterns of supportive services among hospitals demonstrate that initiatives to improve the availability of the entire range of supportive services to all patients should be carefully targeted.

INTRODUCTION: The combination of checkpoint inhibition and cisplatin-based chemotherapy is investigated in muscle invasive bladder cancer (MIBC) and results from phase 2 trials have been presented. Intravesical BCG has been used for non-MIBC (NMIBC) in patients with carcinoma in situ and high-grade Ta/T1 tumours. BCG induces innate and adapted immune response and upregulation of PD-L1 in preclinical models. The proposed trial is intended to implement a new immuno-immuno-chemotherapy induction therapy for MIBC. The combination of BCG and checkpoint inhibition with chemotherapy aims at higher intravesical responses and better local and systemic control of disease. METHODS AND ANALYSIS: SAKK 06/19 is an open-label single-arm phase II trial for patients with resectable MIBC T2-T4a cN0-1. Intravesical recombinant BCG (rBCG: VPM1002BC) is applied weekly for three instillations followed by four cycles of neoadjuvant cisplatin/gemcitabine every 3 weeks. Atezolizumab 1200 mg every 3 weeks is started together with rBCG and given for four cycles. All patients then undergo restaging and radical cystectomy and pelvic lymphadenectomy. Atezolizumab is continued as maintenance therapy after surgery every 3 weeks for 13 cycles. Pathological complete remission is the primary endpoint. Secondary endpoints include pathological response rate (Assuntos

RESUMO
BACKGROUND: Cervical cancer ranks as the second most frequent cancer among all women in Ethiopia and the second most frequent cancer among women between 15 and 44 years of age, resulting in over 4884 moralities annually. Although there is a focus on health promotion through teaching and screening in Ethiopia's intended transition toward universal healthcare, there is little information available on baseline levels of knowledge and screening uptake related to cervical cancer. OBJECTIVES: This study explored the levels of knowledge and screening rates of cervical cancer along with its associated factors among women of reproductive age in Assosa Zone, Benishangul-Gumuz, Ethiopia in 2022. METHODOLOGY: A facility-based cross-sectional study was conducted. A systematic sampling technique was used to select 213 reproductive-age women from selected health institutions, from 20 April 2022 to 20 July 2022. A validated and pretested questionnaire was used for data collection. Multi-logistic regression analyses were done to identify factors independently associated with cervical cancer screening. Adjusted OR with 95% CI was estimated to measure the strength of association. The level of statistical significance was declared at a p value of <0.05. The results were presented in tables and figures. RESULT: Knowledge of cervical cancer screening in this study was 53.5%, and 36% of respondents had practised cervical cancer screening. Family history of cervical cancer (AOR)=2.5, 95% CI (1.04 to 6.44)), place of residence (AOR=3.68, 95% CI (2.23, 6.54)) and availability of health services at nearby (AOR=2.03, 95% CI (1.134, 3.643)) were significantly associated with knowledge of cervical cancer screening, while educational status (AOR=2.811, 95% CI (1.038 to 7.610)), knowing someone diagnosed with cervical cancer (AOR=8.3, 95% CI (2.4, 28.69)), Knowledge of cervical cancer(AOR=2.17, 95%CI(1.077, 4.384) and feeling feeling at risk (AOR=3.26 95% CI (1.52, 5.04)) were associated with the practice of cervical cancer screening. CONCLUSION AND RECOMMENDATION: Knowledge and practice of cervical cancer screening in this study were low. Therefore, the reproductive women must be encouraged to have early cervical cancer screening at precancerous stage by informing their susceptibility to cervical cancer.

OBJECTIVES: To compare the prognostic values of three lymph node staging systems in renal cell carcinoma (RCC), including the number of positive lymph nodes (NPLN), lymph node ratio (LNR) and log odds of positive lymph nodes (LODDS). DESIGN: A retrospective cohort study using data from the Surveillance, Epidemiology and End Results (SEER) database. SETTING AND PARTICIPANTS: 1904 patients with pathological N1 RCC, diagnosed from 2004 to 2015 and underwent nephrectomy combined with lymph node dissection, were identified from the SEER database. PRIMARY OUTCOME MEASURE: The primary outcome of this study was overall survival (OS). Restricted cubic spline functions and multivariable Cox regression analyses were employed to characterise the associations of OS with NPLN, LNR and LODDS, respectively. RESULTS: Data of 1904 eligible RCC patients were extracted from the SEER database. The mortality risks of RCC patients increased with the increasing of NPLN, LNR and LODDS. NPLN (NPLN3 vs NPLN1, HR 1.22, 95% CI 1.05 to 1.43, p=0.001), LNR (LNR3 vs LNR1, HR 1.46, 95% CI 1.28 to 1.67, p<0.001; LNR2 vs LNR1, HR 1.28, 95% CI 1.09 to 1.50, p=0.002) and LODDS (LODDS3 vs LODDS1, HR 1.48, 95% CI 1.28 to 1.72, p<0.001; LODDS2 vs LODDS1, HR 1.34, 95% CI 1.17 to 1.53, p<0.001) were all independent prognostic factors of OS. The predictive abilities of LNR (Akaike information criterion, AIC: 19576.3, optimism-corrected C-index: 0.677) and LODDS (AIC: 19579.2, optimism-corrected C-index: 0.676) were comparable, superior to NPLN (AIC: 19603.7, optimism-corrected C-index: 0.673). In subgroup analyses, the LODDS classification could better stratify survival of RCC patients, in particular for those with the number of dissected lymph nodes <13 or NPLN≤2. CONCLUSIONS: NPLN, LNR and LODDS were all independent predictors of OS in RCC. When compared with NPLN and LNR, LODDS had a better performance in survival prediction and risk stratification. The three metrics all had the potential to be integrated into future versions of the American Joint Committee on Cancer staging manual.

INTRODUCTION: This is a multicentre, open-label, single-arm clinical trial to evaluate the efficacy and safety of apalutamide in patients with metastatic castration-resistant prostate cancer. METHODS AND ANALYSIS: The trial will be performed at 4 university hospitals and 14 city hospitals in Japan. The target number of patients will be 110. The patients will be orally administered 240 mg apalutamide once daily during the treatment period. The primary outcome is the prostate-specific antigen (PSA) response rate. PSA response is defined as ≥50% decline from baseline at 12 weeks. Secondary outcomes are time to PSA progression, progression-free survival, overall survival, progression-free survival during second therapy, ≥50% decline in PSA from baseline at 24 and 48 weeks, ≥90% decline in PSA from baseline or lower PSA detection sensitivity after the initial dose at 12, 24 and 48 weeks, PSA maximal changes, accumulated PSA response from screening to 24 and 48 weeks, and grade 3 or 4 adverse events according to the Common Terminology Criteria for Adverse Events version 4.0. ETHICS AND DISSEMINATION: This study has been approved by the Certified Research Review Board of Kobe University (No. CRB5180009). All participants will be required to provide written informed consent. Findings will be disseminated through scientific and professional conferences and peer-reviewed journal publications. The datasets generated during the study will be available from the corresponding author on reasonable request. TRIAL REGISTRATION NUMBER: jRCTs051220077.

INTRODUCTION: Radical cystectomy (RC) is the standard treatment for patients with non-metastatic muscle-invasive bladder cancer, as well as for patients with therapy refractory high-risk non-muscle invasive bladder cancer. However, 50-65% of patients undergoing RC experience perioperative complications. The risk, severity and impact of these complications is associated with a patient's preoperative cardiorespiratory fitness, nutritional and smoking status and presence of anxiety and depression. There is emerging evidence supporting multimodal prehabilitation as a strategy to reduce the risk of complications and improve functional recovery after major cancer surgery. However, for bladder cancer the evidence is still limited. The aim of this study is to investigate the superiority of a multimodal prehabilitation programme versus standard-of-care in terms of reducing perioperative complications in patients with bladder cancer undergoing RC. METHODS AND ANALYSIS: This multicentre, open label, prospective, randomised controlled trial, will include 154 patients with bladder cancer undergoing RC. Patients are recruited from eight hospitals in The Netherlands and will be randomly (1:1) allocated to the intervention group receiving a structured multimodal prehabilitation programme of approximately 3-6 weeks, or to the control group receiving standard-of-care. The primary outcome is the proportion of patients who develop one or more grade ≥2 complications (according to the Clavien-Dindo classification) within 90 days of surgery. Secondary outcomes include cardiorespiratory fitness, length of hospital stay, health-related quality of life, tumour tissue biomarkers of hypoxia, immune cell infiltration and cost-effectiveness. Data collection will take place at baseline, before surgery and 4 and 12 weeks after surgery. ETHICS AND DISSEMINATION: Ethical approval for this study was granted by the Medical Ethics Committee NedMec (Amsterdam, The Netherlands) under reference number 22-595/NL78792.031.22. Results of the study will be published in international peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT05480735.

OBJECTIVES: Late presentation and delays in diagnosis and treatment consistently translate into poor outcomes in sub-Saharan Africa (SSA). The aim of this study was to collate and appraise the factors influencing diagnostic and treatment delays of adult solid tumours in SSA. DESIGN: Systematic review with assessment of bias using Risk of Bias in Non-randomised Studies of Exposures (ROBINS-E) tool. DATA SOURCES: PubMed and Embase, for publications from January 1995 to March 2021. ELIGIBILITY CRITERIA: Inclusion criteria: quantitative or mixed-method research, publications in English, on solid cancers in SSA countries. EXCLUSION CRITERIA: paediatric populations, haematologic malignancies, and assessments of public perceptions and awareness of cancer (since the focus was on patients with a cancer diagnosis and treatment pathways). DATA EXTRACTION AND SYNTHESIS: Two reviewers extracted and validated the studies. Data included year of publication; country; demographic characteristics; country-level setting; disease subsite; study design; type of delay, reasons for delay and primary outcomes. RESULTS: 57 out of 193 full-text reviews were included. 40% were from Nigeria or Ethiopia. 70% focused on breast or cervical cancer. 43 studies had a high risk of bias at preliminary stages of quality assessment. 14 studies met the criteria for full assessment and all totaled to either high or very high risk of bias across seven domains. Reasons for delays included high costs of diagnostic and treatment services; lack of coordination between primary, secondary and tertiary healthcare sectors; inadequate staffing; and continued reliance on traditional healers and complimentary medicines. CONCLUSIONS: Robust research to inform policy on the barriers to quality cancer care in SSA is absent. The focus of most research is on breast and cervical cancers. Research outputs are from few countries. It is imperative that we investigate the complex interaction of these factors to build resilient and effective cancer control programmes.

INTRODUCTION: Patients undergoing prostate radiotherapy with an enlarged prostate can have short-term and long-term urinary complications. Currently, transurethral resection of the prostate (TURP) is the mainstay surgical intervention for men with urinary symptoms due to an enlarged prostate prior to radiotherapy. UroLift (NeoTract, Pleasanton, CA, USA) is a recent minimally invasive alternative, widely used in benign disease but is untested in men with prostate cancer. METHODS AND ANALYSIS: A multicentre, two-arm study designed in collaboration with a Patient Reference Group to assess the feasibility of randomising men with prostate cancer and coexisting urinary symptoms due to prostate enlargement to TURP or UroLift ahead of radiotherapy. 45 patients will be enrolled and randomised (1:1) using a computer-generated programme to TURP or UroLift. Recruitment and retention will be assessed over a 12 month period. Information on clinical outcomes, adverse events and costs will be collected. Clinical outcomes and patient reported outcome measures will be measured at baseline, 6 weeks postintervention and 3 months following radiotherapy. A further 12 in-depth interviews will be conducted with a subset of patients to assess acceptability using the Theoretical Framework of Acceptability. Descriptive analysis on all outcomes will be performed using Stata (StataCorp V.2021). ETHICS AND DISSEMINATION: The trial has been approved by the Research Ethics Committee (REC) NHS Health Research Authority (HRA) and Health and Care Research Wales (HCRW). The results will be published in peer-reviewed journals, presented at national meetings and disseminated to patients via social media, charity and hospital websites. TRIAL REGISTRATION NUMBER: NCT05840549.

INTRODUCTION: Multiparametric MRI (mpMRI) has transformed the prostate cancer diagnostic pathway, allowing for improved risk stratification and more targeted subsequent management. However, concerns exist over the interobserver variability of images and the applicability of this model long term, especially considering the current shortage of radiologists and the growing ageing population. Artificial intelligence (AI) is being integrated into clinical practice to support diagnostic and therapeutic imaging analysis to overcome these concerns. The following report details a protocol for a systematic review and meta-analysis investigating the accuracy of AI in predicting primary prostate cancer on mpMRI. METHODS AND ANALYSIS: A systematic search will be performed using PubMed, MEDLINE, Embase and Cochrane databases. All relevant articles published between January 2016 and February 2023 will be eligible for inclusion. To be included, articles must use AI to study MRI prostate images to detect prostate cancer. All included articles will be in full-text, reporting original data and written in English. The protocol follows the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols 2015 checklist. The QUADAS-2 score will assess the quality and risk of bias across selected studies. ETHICS AND DISSEMINATION: Ethical approval will not be required for this systematic review. Findings will be disseminated through peer-reviewed publications and presentations at both national and international conferences. PROSPERO REGISTRATION NUMBER: CRD42021293745.

INTRODUCTION: Cabozantinib monotherapy is an option for treatment of advanced renal cell carcinoma (RCC). However, cabozantinib dose modification and discontinuation due to symptomatic adverse events (AEs) remains a challenge. The use of patient-reported outcomes (PROs) may help manage symptomatic AEs, which is reported to lead to improved quality of life (QOL), avoidance of drug discontinuation and better survival. This study aims to investigate the clinical benefits of PROs in patients with RCC receiving cabozantinib and the most appropriate medium for PRO monitoring (electronic [e]-PRO or paper-PRO). METHODS AND ANALYSIS: This study is being conducted at about 35 sites in Japan. Patients aged ≥18 years with unresectable or metastatic RCC initiating treatment with cabozantinib monotherapy are eligible and will be randomised to: (1) e-PRO monitoring, (2) paper-PRO monitoring or (3) usual care without PRO monitoring. Recruitment began in December 2021 (target sample size, 105). Patients start treatment with cabozantinib 60 mg once daily, and in the PRO groups, will record daily medication intake, weight, temperature, blood pressure and AEs. Endpoints include the proportion of patients with a ≥5-point deterioration on the Functional Assessment of Cancer Therapy-Kidney Cancer Symptom Index (FKSI-19; primary endpoint), progression-free survival, QOL, dose adjustments, relative dose intensity, treatment-emergent AEs and frequency of interventions for AEs outside of the scheduled visits. Patient and physician opinions of the PRO monitoring systems and patient compliance with e-PRO/paper-PRO input are also being measured. ETHICS AND DISSEMINATION: The study is being conducted in compliance with the Declaration of Helsinki, the International Council for Harmonisation guidelines for Good Clinical Practice and the Clinical Trials Act. Written informed consent is being obtained from all patients, and the protocol has been approved by the Hokkaido University Hospital Certified Review Board (approval number, CRB021-005). The results will be presented at conferences and submitted to a peer-reviewed journal. TRIAL REGISTRATION NUMBER: jRCTs011210055.
