EAU-EANM-ESTRO-ESUR-SIOG Guidelines on Prostate Cancer—2020 Update. Part 1: Screening, Diagnosis, and Local Treatment with Curative Intent

The European Association of Urology (EAU)-European Association of Nuclear Medicine (EANM)-European Society for Radiotherapy and Oncology (ESTRO)-European Society of Urogenital Radiology (ESUR)-International Society of Urological Pathology (ISUP)-International Society of Geriatric Oncology (SIOG) guidelines provide recommendations for the management of clinically localised prostate cancer (PCa). This paper aims to present a summary of the 2024 version of the EAU-EANM-ESTRO-ESUR-ISUP-SIOG guidelines on the screening, diagnosis, and treatment of clinically localised PCa.The panel performed a literature review of all new data published in English, covering the time frame between May 2020 and 2023. The guidelines were updated, and a strength rating for each recommendation was added based on a systematic review of the evidence.A risk-adapted strategy for identifying men who may develop PCa is advised, generally commencing at 50 yr of age and based on individualised life expectancy. The use of multiparametric magnetic resonance imaging in order to avoid unnecessary biopsies is recommended. When a biopsy is considered, a combination of targeted and regional biopsies should be performed. Prostate-specific membrane antigen positron emission tomography imaging is the most sensitive technique for identifying metastatic spread. Active surveillance is the appropriate management for men with low-risk PCa, as well as for selected favourable intermediate-risk patients with International Society of Urological Pathology grade group 2 lesions. Local therapies are addressed, as well as the management of persistent prostate-specific antigen after surgery. A recommendation to consider hypofractionation in intermediate-risk patients is provided. Patients with cN1 PCa should be offered a local treatment combined with long-term intensified hormonal treatment.The evidence in the field of diagnosis, staging, and treatment of localised PCa is evolving rapidly. These PCa guidelines reflect the multidisciplinary nature of PCa management.This article is the summary of the guidelines for "curable" prostate cancer. Prostate cancer is "found" through a multistep risk-based screening process. The objective is to find as many men as possible with a curable cancer. Prostate cancer is curable if it resides in the prostate; it is then classified into low-, intermediary-, and high-risk localised and locally advanced prostate cancer. These risk classes are the basis of the treatments. Low-risk prostate cancer is treated with "active surveillance", a treatment with excellent prognosis. For low-intermediary-risk active surveillance should also be discussed as an option. In other cases, active treatments, surgery, or radiation treatment should be discussed along with the potential side effects to allow shared decision-making.

Prostate cancer is a global health problem, but incidence varies considerably across different continents. Asia is traditionally considered a low-incidence area, but the incidence and mortality of prostate cancer have rapidly increased across the continent. Substantial differences in epidemiological features have been observed among different Asian regions, and incidence, as well as mortality-to-incidence ratio, is associated with the human development index. Prostate cancer mortality decreased in Japan and Israel from 2007 to 2016, but mortality has increased in Thailand, Kyrgyzstan and Uzbekistan over the same period. Genomic analyses have shown a low prevalence of ERG oncoprotein in the East Asian population, alongside a low rate of PTEN loss, high CHD1 enrichments and high FOXA1 alterations. Contributions from single-nucleotide polymorphisms to prostate cancer risk vary with ethnicity, but germline mutation rates of DNA damage repair genes in metastatic prostate cancer are comparable in Chinese and white patients from the USA and UK. Pharmacogenomic features of testosterone metabolism might contribute to disparities seen in the response to androgen deprivation between East Asian men and white American and European men. Overall, considerable diversity in epidemiology and genomics of prostate cancer across Asia defines disease characteristics in these populations, but studies in this area are under-represented in the literature. Taking into account this intracontinental and intercontinental heterogeneity, translational studies are required in order to develop ethnicity-specific treatment strategies.

Epidemiology and genomics of prostate cancer in Asian men

Summary Roughly 50% of cancer cases occur in people aged 65 years or older. Older people are often diagnosed at a later stage and might receive less (intensive) treatment, which might affect the outcome. In addition, an older age might be associated with biological differences in tumour and microenvironment behaviour, a domain that has been poorly studied so far. In this narrative Review of published literature, we explored the reported differences in tumour biology according to age in five major cancer types: breast, colorectal, prostate, lung, and melanoma. Our literature search uncovered clear differences in tumour histology and subtype distribution in older people compared with younger patients, as well as age-specific patterns of tumour mutations and other molecular alterations. Several studies also indicate notable changes in tumour-infiltrating immune cells in tumours of older versus younger people, although this research is still in its infancy. More research is needed and might lead to a better understanding of the biology of ageing in relation to malignancy. This knowledge could provide new perspectives for more personalised cancer treatments, eventually improving the global outcomes of older patients with cancer.

Is cancer biology different in older patients

Despite substantial improvements in the outcomes of patients with cancer over the past two decades, older adults (aged ≥65 years) with cancer are a rapidly increasing population and continue to have worse outcomes than their younger counterparts. Managing cancer in this population can be challenging because of competing health and ageing-related conditions that can influence treatment decision-making and affect outcomes. Geriatric screening tools and comprehensive geriatric assessment can help to identify patients who are most at risk of poor outcomes from cancer treatment and to better allocate treatment for these patients. The use of evidence-based management strategies to optimize geriatric conditions can improve communication and satisfaction between physicians, patients and caregivers as well as clinical outcomes in this population. Clinical trials are currently underway to further determine the effect of geriatric assessment combined with management interventions on cancer outcomes as well as the predictive value of geriatric assessment in the context of treatment with contemporary systemic therapies such as immunotherapies and targeted therapies. In this Review, we summarize the unique challenges of treating older adults with cancer and describe the current guidelines as well as investigational studies underway to improve the outcomes of these patients.

Rectal spacers for prostate cancer: Real world data and potential uses

519 Background: Muscle-invasive bladder cancer (MIBC) is managed with radical cystectomy or (chemo)radiotherapy ((C)RT), CRT offers the chance of cure alongside organ preservation. Patients presenting with MIBC are often elderly and frail, with comorbidities precluding cystectomy and systemic treatment. We report outcome data for our institution of patients treated with radical (C)RT. Methods: Patients with T2-4N0 MIBC diagnosed between December 2014 and December 2021 were retrospectively identified from the radiotherapy planning system. Baseline demographic, clinical and follow up data were collated from electronic patient records. Results: 54 patients were identified. Mean patient age was 78.5 (range 47 – 94); 51 patients had urothelial cancer and 3 squamous cell carcinoma. 20 patients had evidence of carcinoma in situ (CIS) at diagnosis. 19 patients had neoadjuvant chemotherapy (NACT) (13 patients had cisplatin-gemcitabine, 6 patients had carboplatin-gemcitabine). 12/19 patients completed 3 cycles of NACT, 7 patients received 1-2 cycles. 24/54 patients had concurrent chemotherapy (6 patients receiving mitomycin-5-FU, 17 weekly gemcitabine and 1 weekly cisplatin). 14/24 patients completed concurrent chemotherapy as planned. Of the 24 patients treated with CRT, 18 had NACT. 12 patients received 64 Gy 32 fractions, 2 received 60 Gy 30 fractions, and 40 received 55 Gy 20 fractions. All except 1 patient completed the prescribed course. With a median follow up of 9.4 months (range 0.7-79 months), 3-year overall survival was 43% for all patients; 63% with CRT and 21% with RT alone (log-rank test p=0.0052 HR 3.15 (95% CI 1.48-6.7)). At 3 years 49% were free of recurrence (distant or local); 72% with CRT and 25% with RT alone (log-rank test 0.0079 HR 3.12 (95% CI 1.38-7.01)). 3yr OS and % free of recurrence were not impacted by the presence of CIS. OS was 46% with CIS and 41% without (log-rank test p=0.6649); 3yr % free of recurrence was 43% with CIS and 49% without (log-rank test p=0.4055). Median time to recurrence with CIS was shorter at 13.3 months vs 26.1 months. Conclusions: Radical radiotherapy to the bladder is an effective option for the treatment of MIBC and should be routinely discussed with patients. Patients should be treated with CRT as opposed to RT alone as both OS and RFS are significantly improved. Ensuring patients are fit to receive systemic treatment alongside RT may require prehabilitation in this elderly and more co-morbid group.

Radical radiotherapy for muscle-invasive bladder cancer: A single centre experience.

Abstract Background: Prostate cancer is a common malignancy with rising incidence in Western countries such as the United Kingdom. In localised disease there are a variety of curative treatment modalities. Patients can be referred for surgery, or for a combination of hormonal therapies and radiotherapy (external beam radiotherapy or brachytherapy). Each treatment option comes with side effects and in the case of radiotherapy one potential complication is bowel toxicity from radiation exposure. New technologies are being developed to try and mitigate the side effects and long term morbidity of this treatment, and to expand access to radiotherapy for patients who may previously have been excluded (i.e those with inflammatory bowel disease). Rectal Spacers are absorbable polyethylene glycol hydrogels injected into the perirectal space. These position the anterior rectal wall away from the prostate, subsequently minimising radiation dose to the rectum. Rectal Spacers have been introduced to National Healthcare Service (NHS) practice as part of the Innovation and Technology Payment (ITP) programme, however, their use is now under review. Methodology and Results: In this editorial we conduct a narrative review of some of the available evidence for Rectal Spacers, discuss their utilization within the NHS and the barriers to their wider use. We also explore preliminary dosimetry and quality of life data for use of Rectal Spacers in our centre where we have been part of the NHS ITP programme. Dosimetry data and Quality of life questionnaires were gathered from 22 treated patients and 11 matched controls. This indicated lower radiation doses to the prostate in those treated with Rectal Spacers. Conclusion: Rectal Spacers are an effective method to reduce radiation dose to the prostate in men treated for localised prostate cancer, however, their use remains under review in the NHS and there are a variety of barriers to upscaling their use.
