Abstract
The management of haematuria, in patients with a palliative diagnosis, refractory to standard measures presents a significant challenge for multidisciplinary teams. Our experiences with two cases led us to review the literature and highlighted the limited evidence base. We describe the cases here and propose options for medical approaches to management. We also report on successful use of a nonconjugated oestrogen which has a lower VTE risk compared to conjugated oestrogens. We aim to help support clinicians manage other palliative patients with this challenging symptom in future. Relevant references for this review were identified through searches of PubMed using the terms "haematuria," "hematuria," "palliative," "antifibrinolytic," "tranexamic acid," "etamsylate" "glucocorticoid," "oestrogen," "estrogen," "estradiol," "somatostatin," "thalidomide," hyperbaric oxygen" and "intravesical hyaluronic acid." Other references were suggested by the authors.

Abstract
OBJECTIVE To investigate the prevalence and severity of pelvic floor disorders (PFD), and the associations between treatment type and PFD, and cancer stage and PFD in patients before and after hysterectomy for gynaecological cancer; and the changes in outcomes over time. DESIGN Longitudinal cohort study. SETTING Gynaecological oncology outpatient clinics. POPULATION Patients undergoing hysterectomy for endometrial, uterine, ovarian or cervical cancer. METHODS Participants were assessed before, and 6 weeks and 3 months after hysterectomy. Changes over time were analysed using generalised estimating equations or linear mixed models. Associations were analysed using logistic regression models and analyses of variance. MAIN OUTCOME MEASURES Incontinence Severity Index, Pelvic Floor Distress Inventory-short form (PFDI-20), Female Sexual Function Index. RESULTS Of 277 eligible patients, 126 participated. Prevalence rates of PFD were high before (urinary incontinence [UI] 66%, faecal incontinence [FI] 12%, sexual inactivity 73%) and after (UI 59%, FI 14%, sexual inactivity 58%) hysterectomy. Receiving adjuvant therapy led to moderate-to-very severe UI 3 months after surgery compared with surgery only (odds ratio 4.98, 95% CI 1.63-15.18). There was no association between treatment type and other PFD, or cancer stage and any PFD. CONCLUSION Prevalence of PFD was high before and after hysterectomy for gynaecological cancer. Moderate-to-very-severe UI was associated with adjuvant therapy.

Incidence and Management of Radiation Cystitis After Pelvic Radiotherapy for Prostate Cancer: Analysis From a National Database. Urology 2024; 191:86-92. [PMID: 38692496 DOI: 10.1016/j.urology.2024.04.035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2024] [Revised: 04/18/2024] [Accepted: 04/20/2024] [Indexed: 05/03/2024]
Abstract
OBJECTIVE To determine the incidence of radiation cystitis on prostate cancer (PCa) patients undergoing pelvic radiotherapy (RT), evaluating the most used management strategies, and identifying potential risk factors associated with the development of this condition. METHODS A retrospective analysis was conducted using the PearlDiver Mariner database, containing patient records compiled between 2011 and 2022. International Classification of Diseases (ICD) and Current Procedural Terminology (CPT) codes were employed to identify population and outcomes. We evaluated patients who underwent RT for PCa and subsequently developed radiation cystitis. Primary objective was to determine the overall incidence of radiation cystitis. Furthermore, we investigated its associated risk factors and management. RESULTS A total of 274,865 PCa patients underwent RT during the study period. Of these, 48,713 (17.7%) experienced hematuria following RT, while 7721 (2.8%) were diagnosed with radiation cystitis. After the diagnosis, 2307 patients (29.9%) received diagnostic or therapeutic endoscopic interventions. Only 59 patients (0.76%) underwent endovascular embolization, while 151 patients (1.95%) required cystectomy. Hyperbaric oxygen therapy, administered to 1287 patients (16.67%), was the only treatment that displayed a significant upward trend. Multivariate logistic regression identified obesity (OR 1.29; 95% CI 1.23-1.35), smoking (OR 1.27; 95% CI 1.22-1.33), and diabetes (OR 1.32; 95% CI 1.26-1.39), as significant risk factors for radiation cystitis (all P-values <.001). CONCLUSION Radiation cystitis represents a rare complication after pelvic RT with significant clinical impact. Its incidence has remained stable throughout the study period. The identified risk factors corroborate the pathophysiology of radiation cystitis. Hyperbaric oxygen therapy was the only treatment to show an upward trend during the study period.

Abstract
Background: Radiation-induced hemorrhagic cystitis (RHC) is a chronic inflammatory disease in patients undergoing radiation therapy that causes a cluster of symptoms which may have a latent period of months to years. The current non-invasive treatments include drug treatment and hyperbaric oxygen therapy (HBOT), which has been widely applied for RHC so far but with limited evidence. Thus, we conducted a systematic review and meta-analysis to clarify the effects and safety of HBOT for RHC. Methods: A systematic review and meta-analysis were utilized, searching in the databases of Embase, Pubmed, and Web of Science. The primary endpoint of the present study was complete remission of hematuria. The meta-analysis was conducted using a random effects model, and a pooled odds ratio with 95% CI was calculated. Results: A total of 317 studies were searched and fourteen articles with 556 patients were collected. The results showed that a total of 500 patients (89.9%) had symptom improvement, and the pooled results demonstrated that 55% of patients with HBOT had complete remission of hematuria (95% CI 51-59%). Conclusions: A significant improvement of symptoms when treated with HBOT was shown in this meta-analysis for patients with RHC.

Abstract
PURPOSE Chronic radiation cystitis (CRC) develops after radiation therapy and can present with symptoms like urinary frequency, urgency, pelvic pain, and nocturia. We have previously reported that amniotic bladder therapy (ABT) provides symptomatic improvement in refractory CRC patients for up to 3 months. Herein, we evaluated the durability of ABT up to 6 months. MATERIALS AND METHODS CRC patients recalcitrant to previous treatments received ABT comprised of intra-detrusor injections of 100 mg micronized AM diluted in 10 mL 0.9% preservative-free sodium chloride. Clinical evaluation and questionnaires (Interstitial Cystitis Symptom Index (ICSI), Interstitial Cystitis Problem Index (ICPI), Bladder Pain/Interstitial Cystitis Symptom Score (BPIC-SS), Overactive Bladder (OAB) Assessment Tool, SF-12 Health Survey) were repeated at pre-op and 2, 4, 8, 12, 16, 20, 24, and 36 weeks post-injection. RESULTS Five consecutive patients with a mean age of 64.4 ± 20.1 years with a median CRC duration of 10 years were included and followed for 6 months. After ABT, the lower urinary tract symptoms improved as early as 2 weeks and were maintained up to 20 weeks. BPIC significantly improved from 36.6 ± 1.1 at baseline to 12.6 ± 1.5 at 16 weeks and 13.8 ± 2.9 at 20 weeks. At 24 and 36 weeks, the improvement was maintained in four (80%) of the five patients (BPIC = 13.8 ± 1.0). Uroflow assessment showed voiding volume improved two-fold in four of the five patients at 24 weeks compared to baseline. CONCLUSION Our data suggest that a significant number of CRC patients may have durable benefit after ABT. Despite this, some of them can show symptoms rebound at 24 weeks.

Abstract
PURPOSE The occurrence of genitourinary (GU) toxicity is a common adverse event observed after external beam radiation therapy (EBRT) for prostate cancer (PCa). Recent findings suggest that the dose delivered to specific urinary organs at risk (OARs) such as the ureters, bladder trigone, and urethra is involved in the development of GU toxicity. METHODS AND MATERIALS A multidisciplinary task force including 3 radiation oncologists, a uroradiologist, and a urologist was created in 2022. First, OARs potentially involved in GU toxicity were identified and discussed. A literature review was performed, addressing several questions relative to urinary OARs: anatomic and radiological definition, radiation-induced injury, and dose-volume parameters. Second, results were presented and discussed with a panel of radiation oncologists and members of the "Francophone Group of Urological Radiation Therapy." Thereafter, the "Francophone Group of Urological Radiation Therapy" experts were asked to answer a dedicated questionnaire, including 35 questions on the controversial issues related to the delineation of urinary OARs. RESULTS The following structures were identified as critical for PCa EBRT: ureters, bladder, bladder neck, bladder trigone, urethra (intraprostatic, membranous, and spongious), striated sphincter, and postenucleation or posttransurethral resection of the prostate cavity. A consensus was obtained for 32 out of 35 items. CONCLUSIONS This consensus highlights contemporary urinary structures in both the upper and lower urinary tract to be considered for EBRT treatment planning of PCa. The current recommendations also propose a standardized definition of urinary OARs for both daily practice and future clinical trials.

Abstract
BACKGROUNDS Platelet-to-albumin ratio (PAR) is a new systemic inflammatory prognostic indicator associated with many inflammatory diseases. However, its role in radiation cystitis (RC) is obscure. This study aimed to explore whether PAR could be used as an effective parameter for predicting the RC risk in local advanced cervical cancer (CC) treated with radiotherapy. METHODS A total of 319 local advanced CC patients who received radical radiotherapy at Fujian Cancer Hospital were enrolled between December 2018 and January 2021. Demographics and clinical parameters were retrospectively analyzed. Univariate and multivariate analyses were used to identify the risk factors for RC. Backward and stepwise regression was applied to construct two monograms-one with primary significant factors and the other with extra inflammatory biomarkers. A DeLong test was applied to compare the prediction abilities of two nomograms. Calibration curves and decision curve analysis (DCA) evaluated its prediction consistency, discrimination ability, and clinical net benefit. RESULTS Univariate analysis showed that age, tumor size, stage, total radiation dose, pelvic radiation dose, Systemic Immune-Inflammation Index (SII), platelet-to-lymphocyte ratio (PLR), and PAR were significantly associated with RC occurrence (all p < 0.05). Multivariate analyses indicated that age, tumor size, stage, total radiation dose, and PAR were independent factors (all p < 0.05). Then, the area under curve (AUC) value of the nomogramSII+PAR was higher (AUC = 0.774) compared to that of the baseline nomogram (AUC = 0.726) (pDelong = 0.02). Also, the five-cross validation confirmed the stability of the nomogramSII+PAR. Moreover, the calibration curve and DCA exhibited the nomograms' good prediction consistency and clinical practicability. CONCLUSIONS PAR and SII could be valued for CC patients who are treated with radiation therapy. The nomogram based on PAR and SII could stratify patients who need extra intervention and nursing care to prevent bladder radiation damage and improve patients' quality of life.

Abstract
In the past decade, stereotactic body radiation therapy (SBRT) has emerged as a valid treatment option for patients with localized prostate cancer. Despite the promising results of ultra-hypofractionation in terms of tolerance and disease control, the toxicity profile of SBRT for prostate cancer patients with a history of surgical treatment of benign prostate hyperplasia is still underreported. Here we present an overview of the available data on urinary morbidity for prostate cancer patients treated with SBRT after prior surgical treatments for benign prostate hyperplasia. Technical improvements useful to minimize toxicity and possible treatments for radiation-induced urethritis are discussed.

Abstract
PURPOSE OF REVIEW This review provides evidence-based updates for the first-line management approaches for pelvic floor disorders in patients with gynecologic malignancies, as well as important provider considerations when referring for pelvic floor physical therapy. RECENT FINDINGS Currently, there is strong evidence to recommend pelvic floor muscle training as initial treatment for urinary incontinence and for pelvic organ prolapse; some evidence to recommend a more targeted pelvic floor muscle training program for fecal incontinence; and mostly expertise-based evidence to recommend vaginal gels or estrogen to aid with dyspareunia causing sexual dysfunction. More research is greatly needed to understand the role of overactive pelvic floor muscles in survivors with chronic pelvic pain and the treatment of post-radiation pelvic complications such as vaginal stenosis and cystitis. While pelvic floor disorders are common concerns in gynecologic cancer survivors, there are evidence-based initial noninvasive treatment approaches that can provide relief for many individuals.

Abstract
Benign diseases of the lower urinary tract can occur as a result of oncological or neurological diseases or their respective therapies (e.g., surgery or radiation treatment) and can significantly reduce the quality of life for affected patients. Urinary diversion serves as a salvage option when all other therapeutic regimens have been carried out and proven unsuccessful. When selecting the suitable urinary diversion, a comprehensive clinical assessment of the patients is required in order to ensure long-term success. In some cases, a cutaneous, catheterizable pouch offers the last and only option for a long-term and definitive treatment of a patient's condition. Overall, a decreasing trend in the establishment of a continent urinary diversion is observed in Germany. Current data on benign indications for urinary diversion are limited. Therefore, further data collection and research are needed.

Abstract
OBJECTIVE The purpose of this review was to present the different genitourinary complications following pelvic radiotherapy as well as their assessment and treatments. METHODS A review of literature was conducted using Medline/Pubmed database without period restriction. In order to write this article, we also use the 2016 AFSOS, SFRO and AFU recommendations. RESULTS On the one hand, early side effects are common and mild. The symptomatic treatments available generally provide effective relief to patients. On the other hand, late adverse effects need long and complex care. Its side effects alter the quality of life and can be life-threatening. The effects of radiotherapy are irreversible. Except hyperbaric oxygen therapy and hyaluronic acid/chondroitin sulfate instillations, treatments remain symptomatic. Urethrovesical fibroscopy is essential in cases of gross hematuria, and urodynamic assessment (or videourodynamic) can be used in cases of severe vesicosphincter disorders. Pharmacological treatments are less effective than in non-radiation patients, and the morbidity of surgical treatments is higher in this population. CONCLUSION Genitourinary complications after pelvic radiotherapy are frequent and mild in the early phase but rare and severe in the late phase. Their management is based on a vast diagnostic and therapeutic arsenal, but the treatments are only symptomatic, and the sequelae of radiotherapy remains, to date, irreversible.

Abstract
Radiation-induced hemorrhagic cystitis is a refractory disease that can cause severe hematuria and bladder tamponade. Bladder tamponade due to radiation-induced hemorrhagic cystitis can often recur repeatedly and markedly reduce the quality of life. However, no blood test parameter has been studied yet regarding the prevention of bladder tamponade recurrence. An 84-year-old patient with a history of radiation therapy for cervical cancer was repeatedly hospitalized for bladder tamponade due to radiation-induced hemorrhagic cystitis. At each hospitalization, blood transfusions were performed to treat severe anemia as the first treatment, resulting in hematuria improvement, and the patient was discharged without invasive treatments such as transurethral coagulation. However, anemia developed gradually after each discharge. The anemia progression was obviously unrelated to macrohematuria because macrohematuria did not appear during that period. When the serum hemoglobin level decreased below the physiological range, bladder tamponade recurred. Based on these findings, we posited that the monitoring of the serum hemoglobin level could be useful to predict the occurrence of bladder tamponade. We hypothesized that if the serum hemoglobin level did not fall below the physiological range, bladder tamponade would not occur. We treated chronic anemia after determining its cause and kept serum hemoglobin levels within the physiological range. Since the treatment was initiated, bladder tamponade has not recurred in over 27 months. In this case, the monitoring of the serum hemoglobin level was useful to predict the occurrence of bladder tamponade due to radiation-induced hemorrhagic cystitis. By maintaining serum hemoglobin levels within the physiological range, we successfully prevented the recurrence of bladder tamponade due to radiation-induced hemorrhagic cystitis.

Abstract
BACKGROUND AND PURPOSE Late radiation-induced hematuria can develop in prostate cancer patients undergoing radiotherapy and can negatively impact the quality-of-life of survivors. If a genetic component of risk could be modeled, this could potentially be the basis for modifying treatment for high-risk patients. We therefore investigated whether a previously developed machine learning-based modeling method using genome-wide common single nucleotide polymorphisms (SNPs) can stratify patients in terms of the risk of radiation-induced hematuria. MATERIALS AND METHODS We applied a two-step machine learning algorithm that we previously developed for genome-wide association studies called pre-conditioned random forest regression (PRFR). PRFR includes a pre-conditioning step, producing adjusted outcomes, followed by random forest regression modeling. Data was from germline genome-wide SNPs for 668 prostate cancer patients treated with radiotherapy. The cohort was stratified only once, at the outset of the modeling process, into two groups: a training set (2/3 of samples) for modeling and a validation set (1/3 of samples). Post-modeling bioinformatics analysis was conducted to identify biological correlates plausibly associated with the risk of hematuria. RESULTS The PRFR method achieved significantly better predictive performance compared to other alternative methods (all p < 0.05). The odds ratio between the high and low risk groups, each of which consisted of 1/3 of samples in the validation set, was 2.87 (p = 0.029), implying a clinically useful level of discrimination. Bioinformatics analysis identified six key proteins encoded by CTNND2, GSK3B, KCNQ2, NEDD4L, PRKAA1, and TXNL1 genes as well as four statistically significant biological process networks previously shown to be associated with the bladder and urinary tract. CONCLUSION The risk of hematuria is significantly dependent on common genetic variants. The PRFR algorithm resulted in a stratification of prostate cancer patients at differential risk levels of post-radiotherapy hematuria. Bioinformatics analysis identified important biological processes involved in radiation-induced hematuria.

Abstract
OBJECTIVE Radiotherapy plays a vital role as a treatment for malignant pelvic tumors, in which the bladder represents a significant organ at risk involved during tumor radiotherapy. Exposing the bladder wall to high doses of ionizing radiation is unavoidable and will lead to radiation cystitis (RC) because of its central position in the pelvic cavity. Radiation cystitis will result in several complications (e.g. frequent micturition, urgent urination, and nocturia) that can significantly reduce the patient's quality of life and in very severe cases become life-threatening. METHODS Existing studies on the pathophysiology, prevention, and management of radiation-induced cystitis from January 1990 to December 2021 were reviewed. PubMed was used as the main search engine. Besides the reviewed studies, citations to those studies were also included. RESULTS AND DISCUSSIONS In this review, the symptoms of radiation cystitis and the mainstream grading scales employed in clinical situations are presented. Next, preclinical and clinical research on preventing and treating radiation cystitis are summarized, and an overview of currently available prevention and treatment strategies as guidelines for clinicians is provided. Treatment options involve symptomatic treatment, vascular interventional therapy, surgery, hyperbaric oxygen therapy (HBOT), bladder irrigation, and electrocoagulation. Prevention includes filling up the bladder to remove it from the radiation field and delivering radiation based on helical tomotherapy and CT-guided 3D intracavitary brachytherapy techniques.

Abstract
PURPOSE Pelvic radiation therapy (RT) can cause debilitating bladder toxicities but few clinical interventions exist to prevent injury or alleviate symptoms. From a large genome-wide association study in patients with prostate cancer it was previously reported that SNPs tagging AGT, part of the renin-angiotensin system (RAS), correlated with patient-reported late hematuria, identifying a potential targetable pathway to prevent RT-induced bladder injury. To investigate this association, we performed a preclinical study to determine whether RAS modulation protected the bladder against RT injury. METHODS AND MATERIALS C57BL/6 male mice were treated with an oral angiotensin converting enzyme inhibitor (ACEi: 0.3g/L captopril) 5 days before focal bladder X-irradiation with either single dose (SD) 30 Gy or 3 fractions of 8 Gy (8 Gy × 3 in 5 days). RT was delivered using XStrahl SARRP Muriplan CT-image guidance with parallel-opposed lateral beams. ACEi was maintained for 20 weeks post RT. Bladder toxicity was assessed using assays to identify local injury that included urinalysis, functional micturition, bladder-released exosomes, and histopathology, as well as an assessment of systemic changes in inflammatory-mediated circulating immune cells. RESULTS SD and fractionated RT increased urinary frequency and reduced the volume of individual voids at >14 weeks, but not at 4 weeks, compared with nonirradiated animals. Urothelial layer width was positively correlated with mean volume of individual voids (P = .0428) and negatively correlated with number of voids (P = .028), relating urothelial thinning to changes in RT-mediated bladder dysfunction. These chronic RT-induced changes in micturition patterns were prevented by captopril treatment. Focal bladder irradiation significantly increased the mean particle count of urine extracellular vesicles and the monocyte and neutrophil chemokines CCL2 and MIP-2, and the proportions of circulating inflammatory-mediated neutrophils and monocytes, which was also prevented by captopril. Exploratory transcriptomic analysis of bladder tissue implicated inflammatory and erythropoietic pathways. CONCLUSIONS This study demonstrated that systemic modulation of the RAS protected against and alleviated RT-induced late bladder injury but larger confirmatory studies are needed.

Abstract
PURPOSE For decades, Dr. John Moulder has been a leading radiation biologist and one of the few who consistently supported the study of normal tissue responses to radiation. His meticulous modeling and collaborations across the field have offered a prime example of how research can be taken from the bench to the bedside and back, with the ultimate goal of providing benefit to patients. Much of the focus of John's work was on mitigating damage to the kidney, whether as the result of accidental or deliberate clinical exposures. Following in his footsteps, we offer here a brief overview of work conducted in the field of radiation-induced bladder injury. We then describe our own preclinical experimental studies which originated as a response to reports from a clinical genome-wide association study (GWAS) investigating genomic biomarkers of normal tissue toxicity in prostate cancer patients treated with radiotherapy. In particular, we discuss the use of Renin-Angiotensin System (RAS) inhibitors as modulators of injury, agents championed by the Moulder group, and how RAS inhibitors are associated with a reduction in some measures of toxicity. Using a murine model, along with precise CT-image guided irradiation of the bladder using single and fractionated dosing regimens, we have been able to demonstrate radiation-induced functional injury to the bladder and mitigation of this functional damage by an inhibitor of angiotensin-converting enzyme targeting the RAS, an experimental approach akin to that used by the Moulder group. We consider our scientific trajectory as a bedside-to-bench approach because the observation was made clinically and investigated in a preclinical model; this experimental approach aligns with the exemplary career of Dr. John Moulder. CONCLUSIONS Despite the differences in functional endpoints, recent findings indicate a commonality between bladder late effects and the work in kidney pioneered by Dr. John Moulder. We offer evidence that targeting the RAS pathway may provide a targetable pathway to reducing late bladder toxicity.

Abstract
Silk-Elastinlike Protein-Based Polymers (SELPs) can form thermoresponsive hydrogels that allow for the generation of in-situ drug delivery matrices. They are produced by recombinant techniques, enabling exact control of monomer sequence and polymer length. In aqueous solutions SELP strands form physical crosslinks as a function of temperature increase without the addition of crosslinking agents. Gelation kinetics, modulus of elasticity, pore size, drug release, biorecognition, and biodegradation of SELP hydrogels can be controlled by placement of amino acid residues at strategic locations in the polymer backbone. SELP hydrogels have been investigated for delivery of a variety of bioactive agents including small molecular weight drugs and fluorescent probes, oligomers of glycosaminoglycans, polymeric macromolecules, proteins, plasmid DNA, and viral gene delivery systems. In this review we provide a background for use of SELPs in matrix-mediated delivery and summarize recent investigations of SELP hydrogels for controlled delivery of bioactive agents as well as their use as liquid embolics.

Abstract
BACKGROUND Radiation-induced hemorrhagic cystitis is a complication of pelvic radiotherapy, with an incidence of up to 5%. The resultant hematuria may be severe and refractory to conservative measures. Our objective was to describe the pattern of inpatient treatments among a cohort of patients with radiation-induced hemorrhagic cystitis requiring pharmacological management. METHODS We conducted a retrospective case series to identify all inpatient admissions at a single institution during which patients with radiation cystitis underwent pharmacological intervention for refractory hematuria between 2004 and 2019. Patient demographics, medical history, details of radiation therapy, and relevant admission data were collected. Details of treatment, including the use of pharmacotherapy and surgical treatment, were reviewed and summarized. RESULTS We identified 21 patients who were treated during 26 admissions. Most were male (91%) with a history of external beam radiation therapy (86%), primarily for prostate cancer (85%), and a median age of 73 (IQR: 67-85). Most patients received continuous bladder irrigation as the first intervention during their admission (65%), for a median duration of 40 hours (IQR: 25-59). Eleven separate pharmacologic agents were used, with variations in initial pharmacotherapy utilization over time. Most patients were treated with a combination of surgical and pharmacological interventions (85%). The median length of stay was 9 days (IQR: 5-17) and the 90-day readmission rate was 35%. CONCLUSIONS Pharmacologic treatment for refractory radiation-induced hemorrhagic cystitis is inconsistent and lacks evidence to support treatment strategies. Further work is needed to determine the optimal management for this morbid complication.

Abstract
Simple Summary Pathologies of the bladder are called cystitis. They cause discomfort for the patient. Due to persistent pain, bleeding, urinary incontinence, and uncontrolled urination, the chronic forms cause considerable degradation to patient quality of life. Currently, there is no curative treatment for the most severe forms. This is both an economic and a societal problem. Although the different forms of cystitis have different causes, they share common mechanisms. We propose to describe in detail the key processes and the associated mechanisms involved in abacterial cystitis. Abstract Cystitis is a bladder disease with a high rate of prevalence in the world population. This report focuses on Interstitial Cystitis (IC), Hemorrhagic Cystitis (HC) and Chronic Radiation Cystitis. These pathologies have different etiologies, but they share common symptoms, for instance, pain, bleeding, and a contracted bladder. Overall, treatments are quite similar for abacterial cystitis, and include bladder epithelium protective or anti-inflammatory agents, alleviating pain and reducing bleeding. This review summarizes the mechanisms that the pathologies have in common, for instance, bladder dysfunction and inflammation. Conversely, some mechanisms have been described as present in only one pathology, such as neural regulation. Based on these specificities, we propose identifying a mechanism that could be common to all the above-mentioned pathologies.

Abstract
PURPOSE Late radiation tissue injuries (LRTIs) after treatment for pelvic cancer may impair health related quality of life (HRQoL). Hyperbaric oxygen therapy is an adjuvant therapy for LRTIs, but limited studied. The aim of this study was to explore the development and association between symptoms of LRTI and HRQoL following hyperbaric oxygen treatment. METHODS A pretest-posttest design was used to evaluate the changes in pelvic LRTIs and HRQoL from baseline (T1), immediately after treatment (T2) and at six-month follow-up (T3). EPIC and EORTC-QLQ-C30 were used to assess LRTIs and HRQoL. Changes were analysed with t-tests, and associations with Pearson's correlation and multiple regression analyses. RESULTS Ninety-five participants (mean age 65 years, 52.6% men) were included. Scores for urinary and bowel symptoms, overall HRQoL, all function scales and the symptoms scales sleep, diarrhoea, pain and fatigue were significantly improved six months after treatment (P-range = 0.00-0.04). Changes were present already at T2 and maintained or further improved to T3. Only a weak significant correlation between changes in symptoms and overall HRQoL was found (Pearson r-range 0.20-0.27). CONCLUSION The results indicate improvement of pelvic LRTIs and HRQoL following hyperbaric oxygen therapy, corresponding to minimal or moderate important changes. Cancer survivors with pelvic LRTIs and impaired HRQoL may benefit from undergoing hyperbaric oxygen therapy. Especially the reduced symptom-severity and improved social- and role function can influence daily living positively. TRIAL REGISTRATION ClinicalTrials.gov: NCT03570229. Released 2. May 2018.

Abstract
Pelvic radiation is increasingly being used for the neoadjuvant and definitive treatment of pelvic organ malignancy. While this treatment can be highly effective, and may assist in organ sparing, it is also associated with significant toxicity and devastating adverse events that need to be considered. In broad terms, pelvic radiation disease affects both the primary target organ as well as adjacent organs and soft tissue structures, with complications that can be classified and graded according to consensus criteria. The complication grade is often modality, dose, and area dependent. The most common manifestations are proctitis, cystitis, recto-urethral fistula, ureteric stricture, and bone involvement. Toxicity can be misdiagnosed for many years, resulting in significant management delays. Complications can be difficult to prevent and challenging to treat, requiring specialized multi-disciplinary input to achieve the best possible strategy to minimize impact and improve patient quality of life.

Abstract
Chronic radiation cystitis (CRC) is a consequence of pelvic radiotherapy and affects 5–10% of patients. The pathology of CRC is without curative treatment and is characterized by incontinence, pelvic pain and hematuria, which severely degrades patients’ quality of life. Current management strategies rely primarily on symptomatic measures and have certain limitations. Thanks to a better understanding of the pathophysiology of radiation cystitis, studies targeting key manifestations such as inflammation, neovascularization and cell atrophy have emerged and are promising avenues for future treatment. However, the mechanisms of CRC are still better described in animal models than in human models. Preclinical studies conducted to elucidate the pathophysiology of CRC use distinct models and are most often limited to specific processes, such as fibrosis, vascular damage and inflammation. This review presents a synthesis of experimental studies aimed at improving our understanding of the molecular mechanisms at play and identifying key processes in CRC.

Abstract
BACKGROUND AND PURPOSE Significant improvements in the treatment of anal cancer have produced a growing population of anal cancer survivors. These patients often experience late adverse effects related to their treatment. Research has revealed substantial unmet needs because of long-term symptoms and functional impairments after treatment that may negatively affect health-related quality of life. The purpose of the present guidelines is to review the scientific evidence for the management of late adverse effects after (chemo)radiotherapy ([C]RT) for anal cancer and to extrapolate knowledge from other pelvic malignancies treated with pelvic (C)RT so that they may guide the clinical management of late adverse effects. MATERIALS AND METHODS Relevant studies were systematically searched in four databases from their inception to June 2020 (no language limitation) and guidelines were searched in 16 databases, focussing on bowel dysfunction, psychosocial aspects, pain, and sexual and urinary dysfunction. The guidelines were developed by a panel of experts using the Oxford Centre for Evidence-based Medicine, levels of evidence, and grades of recommendations. SCIENTIFIC EVIDENCE Late adverse effects after (C)RT for anal cancer are associated with a low overall quality of life among survivors. The most pronounced late adverse effects are bowel dysfunction (present in up to 78%), urinary dysfunction (present in up to 45%), and sexual dysfunction (present in up to 90% of men and up to 100% of women). Only indirect data on adequate treatment options of these late adverse effects for anal cancer are available. CONCLUSION Quality of life and late adverse effects should be monitored systematically following treatment for anal cancer to identify patients who require further specialist evaluation or support. Increased awareness of the extent of the problem may serve to stimulate and facilitate multidisciplinary collaboration, which is often required.

Abstract
OBJECTIVES To elucidate the national burden of emergency department (ED) visits for radiation cystitis (RC), a known complication of radiation therapy (RT) to the pelvic area, among patients with a prostate cancer history, and identify those who are at increased risk of requiring invasive measures. PATIENTS AND METHODS This study queried the Nationwide Emergency Department Sample for all ED visits from January 2006 to December 2015 with a primary diagnosis of RC and secondary diagnosis of prostate cancer. ED visits were characterised by demographic factors, socioeconomic factors, and hospital characteristics. Weighted frequencies were used to create national estimates for all data analysis. RESULTS A weighted total of 17 382 ED visits occurred for RC among patients with a prostate cancer history, of which 9655 (55.5%) were treated with an invasive procedure. Notable factors associated with undergoing an invasive procedure included having a prior prostatectomy (odds ratio [OR] 5.48, 95% confidence interval [CI] 2.62-11.46), urinary retention (OR 1.35, 95% CI 1.12-1.64), haematuria (OR 1.20, 95% CI 1.01-1.42), and undergoing a blood transfusion (OR 2.12, 95% CI 1.72-2.62). ED visits that were associated with invasive procedures had a higher median total charge ($34 707.53 vs $15 632.53) and an increased median length of stay (5 vs 3 days) compared to visits without an invasive procedure. CONCLUSIONS Among ED visits for RC in prostate cancer, approximately one half required an invasive procedure for treatment. While RT remains an effective modality for patients with prostate cancer, providers should be mindful of RC as a potential complication.

Abstract
INTRODUCTION We aimed to summarize current literature about radiation cystitis treatments, providing physician of a summary of current management options. EVIDENCE ACQUISITION A systematic literature review searching on PubMed (Medline), Scopus, and Web of Science databases was performed in March 2021. PRISMA guidelines were followed. Population consisted of patients with a diagnosis of radiation cystitis after pelvic radiotherapy (P). We focused our attention on different treatments, such as conservative or surgical one (I). Single or multiple arms studies were deemed eligible with no mandatory comparison (C). Main outcomes of interest were symptoms control and adverse events rates (O). EVIDENCE SYNTHESIS The search identified 1,194 records. Of all, four studies focused on the use of hyperbaric oxygen therapy showing complete response rates ranging from 52 to 87% approximately. Oral administration of cranberry compounds was investigated in one study showing no superiority to placebo. Intravesical instillation of different compounds were investigated in five studies showing the highest complete response rates after alum (60%) and formalin administration (75%). Endoscopic conservative surgical treatments (fibrin glue or vaporization) also showed 75% complete response rates. In patients who did not respond to conservative treatments robotic cystectomy is feasible with overall complication rates of about 59.3% at 90 days. CONCLUSIONS Radiotherapy induced cystitis is an under-reported condition after pelvic radiotherapy. Several treatments have been proposed, but in up to 10% of cases salvage cystectomy is necessary. A stepwise approach, with progressive treatment aggressiveness is recommended.

Abstract
PURPOSE To assess the efficacy and safety of intravesical instillation of high molecular weight sodium hyaluronate (HMW-HA) for the treatment of radiation-induced cystitis. METHODS This prospective cohort study was conducted in seven centers in France. Eligible patients with radiation-induced cystitis were recruited between April 2020 and March 2021. A sterile disposable 50 ml prefilled solution containing 0.16% (80 mg/50 mL) HMW-HA (INSTYLAN) was instilled weekly into the bladder. The treatment consisted of 6 sessions (V1 to V6). Outcomes were assessed 1 week (V7) and 4 weeks (V8) after the last session and were compared with baseline (V0). The primary endpoint was bladder pain, evaluated by a Questionnaire with 5 closed-ended response options. Secondary endpoints included changes from baseline for hematuria, urinary frequency, and the effect of urgencies on Quality of Life (QoL). Adverse events (AEs) were graded according to the CTCAE 3.0 classification. RESULTS A total of 30 participants were enrolled. The Intent-to-Treat analysis showed a significant reduction in pelvic pain intensity (- 45.81%, p < 0.001), hematuria (- 26.87%, p = 0.008), total 24 h voids (- 23.92%, p < 0.001) and the effect of urgencies on QoL (- 33.92%, p < 0.001) at V7. The improvement for each outcome remained stable during the post-therapeutic period between V7 and V8. Bladder instillation therapy was well-tolerated: two treatment-related AEs (6.6%) were reported corresponding to two grade 1 hematuria. CONCLUSIONS Intravesical instillation of HMW-HA appears to be effective in the treatment of radiation-induced cystitis. Further comparative studies with longer follow-up are needed to confirm our preliminary results.

Abstract
INTRODUCTION AND OBJECTIVE The management of severe symptoms secondary to radiation changes to the bladder can be difficult. Many patients often endure costly procedures, hospitalizations, transfusions, and physician visits for intractable symptoms. Our aim was to evaluate the short-term efficacy and feasibility of urinary diversion in patients with severe, debilitating symptoms related to radiation cystitis by focusing on perioperative data examining surgical feasibility and assess for any improvement in the number of procedures, transfusions, hospitalizations, and office visits required. METHODS With IRB approval, we queried our institutional database for patients with a diagnosis code of radiation cystitis who underwent urinary diversion with or without bladder removal from 2011 to 2018. We reviewed institutional and regional record to assess pre, peri and postoperative outcomes, including rates of surgical procedures, hospitalizations, transfusions and clinic visits, in the year before and after treatment. Non-parametric statistics and linear regression were used. RESULTS Of the 286 patients with radiation cystitis, 45 patients underwent definitive urinary diversion - 31 with concomitant cystectomy and 14 with diversion alone. Analysis of perioperative variables such as estimated blood loss, surgical time, post-operative hospital stay or complication rates were similar to our experience with cystectomy in non-radiated patients. With a mean follow up of 14.6 months, we found that the number of procedures, hospitalizations and transfusions objectively improved following radical surgery. Office visits, however, did not seem to be impacted by performing urinary diversion. There were no significant differences in post-operative benefits between patients that received a concomitant cystectomy and those that only underwent diversion. CONCLUSION Patients suffering from severe refractory symptomatic radiation cystitis may be best treated with a radical surgical approach. Definitive urinary diversion with or without cystectomy can lower burden of disease by reducing the need for additional procedures, hospitalizations, and blood transfusions on short term follow-up.

Abstract
OBJECTIVES Fibrin glue (FG) endo-vesical application seems to be a promising therapy for hemorrhagic cystitis (HC). We aimed to evaluate efficacy and safety of FG instillation in patients with HC. METHODS Patients with HC not responsive to conventional treatments (bladder irrigation, catheterization, blood transfusions, hyperhydration and endoscopic coagulation) were treated with FG endo-vesical instillation (April 2017- December 2018). FG was prepared from 120 mL of patient blood with the Vivostat® system. After standard cystoscopy, bladder was insufflated with carbon dioxide (CO2) according to bladder compliance and autologous FG was applied to bladder wall and bleeding sites. RESULTS Ten patients included with grade 2 or higher HC secondary to bone marrow graft for hematological diseases (30%) or to actinic cystitis caused by prostate cancer radiotherapy (RT) (70%). The median HC onset time after RT was 4.8 (IQR 3.9- 6.3) years and 35 (IQR 27.5-62.5) days after hematopoietic stem cell transplantation (HSCT). Five patients had a complete response after one treatment, three patients had clinical response (grade < 2 hematuria, amelioration of symptoms), one of them required catheterization and bladder irrigation. One patient required a second instillation of FG achieving a clinical response. No adverse events related to the procedure were recorded, however one patient died for causes not related to the procedure. Median Interstitial Cystitis Symptoms Index was 13.0 (IQR 11.0-15.0) pre-operatively and 4.0 (IQR 2.0-5.0) post-operatively. CONCLUSIONS Our study showed that, even in hematological patients, autologous FG instillation maybe a safe, repeatable and effective treatment modality in patients with refractory HC.

Abstract
BACKGROUND Radiation-induced cystitis is a common side effect of radiotherapy (RT) to the pelvic area. Hyaluronic acid (HA) and chondroitin sulfate (CS) are components of the urothelial mucosa and positive results have been obtained for intravesical HA/CS instillations for the treatment of urinary tract infections and bladder pain syndrome. HA/CS may also have a protective effect against RT bladder toxicity. OBJECTIVE To investigate whether HA and CS protect the urothelium during RT, alleviate lower urinary tract symptoms, and improve quality of life. DESIGN SETTING AND PARTICIPANTS This multicentre randomised controlled trial was conducted across seven centres in four countries. Male patients aged ≥18 yr scheduled to undergo primary intensity-modulated radiotherapy for localised prostate cancer were enrolled. INTERVENTION Patients were randomised to intravesical HA/CS plus an oral formulation of curcumin, quercetin, HA, and CS (group A) or no treatment (group B). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS The primary endpoint was absolute changes from baseline to follow-up in urinary domain scores for the Expanded Prostate Cancer Index Composite (EPIC), the International Consultation on Incontinence Questionnaire-Male Lower Urinary Tract Symptoms (ICIQ-MLUTS), and the EuroQol Group EQ-5D-5L questionnaire. Data analysis for efficacy and safety outcomes was performed using an intention-to-treat (ITT) approach; the ITT population was defined as all randomised patients. RESULTS AND LIMITATIONS Of 57 patients screened, 49 were enrolled and randomly assigned to either active treatment (group A, n = 25) or the control (group B, n = 24). Three patients in the control group withdrew after randomisation. Changes from baseline to 12 mo were worse in the control group for subtotal scores for urinary symptoms and impact of symptoms on quality of life and for the total score (p = 0.05, p = 0.003, and p = 0.008, respectively). There was a significant time × group interaction in favour of active treatment for the incontinence symptom score (p = 0.011) and bother score (p = 0.017). The absence of a sham procedure and/or placebo is the main limitation. CONCLUSIONS Our results suggest that intravesical HA/CS in combination with an oral formulation may reduce urinary symptoms and improve QoL at short-term (1 yr) follow-up. PATIENT SUMMARY We investigated whether hyaluronic acid (HA) and chondroitin sulfate (CS) have a protective effect against the bladder toxicity of radiotherapy for prostate cancer. HA/CS used for weekly bladder irrigation for 6 wk and given orally with curcumin and quercetin for 12 wk reduced urinary incontinence symptoms and bother measured at 1-year follow-up. This may hold promise as a preventive treatment if the results are confirmed in further trials.

Abstract
BACKGROUND Late onset of radiation-induced haemorrhagic cystitis (RHC) after radiation therapy (RT) for prostate cancer (PCa) may present or evolve severely, requiring hospitalization with invasive interventions. In the present study, we have analysed the prevalence and risk factors associated with the onset of RHC. METHODS From January 2002 to May 2017, 1421 patients undertook RT for PCa as a primary, adjuvant, or salvage treatment option. RHC presented in 5.6% (n = 80) of the patients; the diagnosis was based on clinical and endoscopic characteristics. Variables in observation included patients, tumours, and RT-dosimetry characteristics. Patients with a previous history of bladder cancer were excluded. Univariate (Student t/Chi square) and uni-/multivariate Cox regression analysis were performed; the events and time-points were hospitalization and time-to-event, respectively. RESULTS There were 80 patients with a mean age at RT of 70.1 years (SD 6.4), mean time lag to RHC of 43.9 months (SD 37.5). Median Emergency attendance was two and three times for patients without/with hospitalization, respectively. There were in total 64 admissions with invasive treatment required in 26/36 (72.2%) of the patients hospitalised, including transurethral fulguration in 22 and radical cystectomy in 5. Patients at higher risk of hospitalization were those undertaking antiplatelet/anticoagulant treatment (HR:3.30; CI 95%:1.53-3.30; p = 0.002) and those treated with salvage RT with higher bladder volume receiving >70 Gy (bladder V70) (HR:1.03; CI 95%:1.01-1.05; p = 0.027). At receiving operating characteristic analysis, the cutoff for bladder V70 was 29%. CONCLUSION Nearly half of patients presenting RHC may require invasive treatment including cystectomy. Risk factors associated with hospitalization are patients undertaking antiplatelet/coagulant treatment and bladder V70 > 29% in salvage RT patients.

Abstract
Radiation treatments often unfavorably damage neighboring healthy organs and cause a series of radiation sequelae, such as radiation-induced hematopoietic system diseases, radiation-induced gastrointestinal diseases, radiation-induced lung diseases, and radiation-induced skin diseases. Recently, emerging nanomaterials have exhibited good superiority for these radiation-induced disease treatments. Given this background, the rational design principle of nanomaterials, which helps to optimize the therapeutic efficiency, has been an increasing need. Consequently, it is of great significance to perform a systematic summarization of the advances in this field, which can trigger the development of new high-performance nanoradioprotectors with drug efficiency maximization. Herein, this review highlights the advances and perspectives in the rational design of nanomaterials for preventing and treating various common radiation-induced diseases. Furthermore, the sources, clinical symptoms, and pathogenesis/injury mechanisms of these radiation-induced diseases will also be introduced. Furthermore, current challenges and directions for future efforts in this field are also discussed.

Abstract
PURPOSE To identify patient- and treatment-related risk factors for fistula, bleeding, cystitis, pain and difficulty in voiding in locally advanced cervical cancer patients treated with radio(chemo)therapy and image-guided adaptive brachytherapy (IGABT). MATERIAL AND METHODS Morbidity within the EMBRACE-I study was prospectively reported for physician-assessed (CTCAE) fistula, bleeding and cystitis and patient-reported (EORTC) pain and difficulty in voiding. Analysis of risk factors was performed in patients without bladder infiltration. Risk factors were tested with Cox regression for grade (G) ≥ 3 cystitis, for G ≥ 2 fistula, bleeding and cystitis, and for EORTC "very much" and "quite a bit" or worse. RESULTS Of 1416 patients enrolled, 1153 and 884 patients without bladder infiltration were evaluable for the analysis of CTCAE and EORTC items, respectively. Median follow-up was 48[3-120] months. Crude incidence rates for G ≥ 2 fistula, bleeding and cystitis were 0.7%, 2.7% and 8.8%, respectively, and 16% and 14% for "quite a bit" or worse pain and difficulty in voiding, respectively. Baseline urinary morbidity and overweight/obesity were significant risk factors for most endpoints. Bladder D2cm3 correlated with G ≥ 2 fistula, bleeding and cystitis, while ICRU bladder point dose correlated with EORTC pain "quite a bit" or worse. An increase from 75 Gy to 80 Gy in bladder D2cm3 resulted in an increase from 8% to 13% for 4-year actuarial estimate of G ≥ 2 cystitis. CONCLUSION Clinical and treatment-related risk factors for bladder fistula, bleeding and cystitis were identified within a prospective and multi-institutional setting. A dose-effect was established with bladder D2cm3, reinforcing the importance of continued optimization during individualized IGABT planning.

Abstract
Radiation cystitis is a potential complication following the therapeutic irradiation of pelvic cancers. Its clinical management remains unclear, and few preclinical data are available on its underlying pathophysiology. The therapeutic strategy is difficult to establish because few prospective and randomized trials are available. In this review, we report on the clinical presentation and pathophysiology of radiation cystitis. Then we discuss potential therapeutic approaches, with a focus on the immunopathological processes underlying the onset of radiation cystitis, including the fibrotic process. Potential therapeutic avenues for therapeutic modulation will be highlighted, with a focus on the interaction between mesenchymal stromal cells and macrophages for the prevention and treatment of radiation cystitis.

Abstract
Abstract
Background
Cytomegalovirus-related infections are commonly seen in immunocompromised patients. However, haemorrhagic cystitis is an exceptionally rare associated manifestation. We present an unusual case of cytomegalovirus-related haemorrhagic cystitis in a patient with acquired immune deficiency syndrome (AIDS).
Case presentation
A 33-year-old HIV-positive female presented with acute gross haematuria and suprapubic pain. Cystoscopy revealed features suggestive of haemorrhagic cystitis with clots in the bladder and an ulcerative lesion on the left lateral wall which was biopsied. Histology demonstrated the presence of enlarged cells containing eosinophilic intranuclear and ill-defined amphophilic intracytoplasmic inclusions. Immunohistochemistry was positive for cytomegalovirus.
Conclusion
This case appears to be the first of its kind reported in South Africa highlighting the importance of considering cytomegalovirus as a potential infectious aetiology in AIDS patients with haematuria. Bladder irrigation with normal saline with or without clot evacuation combined with Ganciclovir are associated with good outcome.

Abstract
Minimizing the toxicity of radiotherapy is challenging. We investigated the effects of a phosphodiesterase type-5 inhibitor (PDE5I) on the urinary bladder after pelvic radiotherapy. Eight rats were assigned to each group (group 1: control; group 2: radiation; group 3: radiation plus PDE5I). Radiation dose was 10 Gy/one fraction. Udenafil (20 mg/kg, daily for 4 weeks) was administered in group 3. Cystometry was performed 4 weeks after treatment, followed by real-time PCR for PDE5, vascular endothelial growth factor (VEGF), and endothelial nitric oxide synthase (eNOS) mRNA, western blotting for PDE5, cyclic GMP-dependent protein kinase (PRKG), VEGF164, Akt, eNOS and NADPH oxidase (NOX)-2 proteins, and immunohistochemistry for eNOS. The expression of both VEGF mRNA and eNOS mRNA was higher in group 3 than in group 2. VEGF and eNOS protein expression improved with PDE5I treatment. Akt protein phosphorylation was higher in group 3 than in group 2, but NOX-2 protein expression was lower in group 3 than in group 2. Immunohistochemistry showed that the mean density of arterioles expressing eNOS was higher in group 3 than in group 2. Cystometry revealed that the intercontraction interval was remarkably longer in group 3 than in group 2 but that the maximal voiding pressure was higher in group 2 than in group 3. Daily treatment with a PDE5I after radiotherapy may prevent bladder storage dysfunction, potentially due to its effects on vasodilation and angiogenesis and through minimizing tissue oxidative damage by means of the VEGF/Akt/eNOS pathway.

Abstract
Despite the dramatic advancements in pelvic radiotherapy, urinary toxicity remains a significant side-effect. The assessment of clinico-dosimetric predictors of radiation cystitis (RC) based on clinical data has improved substantially over the last decade; however, a thorough understanding of the physiopathogenetic mechanisms underlying the onset of RC, with its variegated acute and late urinary symptoms, is still largely lacking, and data from pre-clinical research is still limited. The aim of this review is to provide an overview of the main open issues and, ideally, to help investigators in orienting future research. First, anatomy and physiology of bladder, as well as the current knowledge of dose and dose-volume effects in humans, are briefly summarized. Subsequently, pre-clinical radiobiology aspects of RC are discussed. The findings suggest that pre-clinical research on RC in animal models is a lively field of research with growing interest in the development of new radioprotective agents. The availability of new high precision micro-irradiators and the rapid advances in small animal imaging might lead to big improvement into this field. In particular, studies focusing on the definition of dose and fractionation are warranted, especially considering the growing interest in hypo-fractionation and ablative therapies for prostate cancer treatment. Moreover, improvement in radiotherapy plans optimization by selectively reducing radiation dose to more radiosensitive substructures close to the bladder would be of paramount importance. Finally, thanks to new pre-clinical imaging platforms, reliable and reproducible methods to assess the severity of RC in animal models are expected to be developed.

Abstract
OBJECTIVE To evaluate the impact of adjuvant radiotherapy (aRT) in patients with prostate cancer (PCa) found to have pathological positive lymph nodes (pN1s) after radical prostatectomy (RP) and extended pelvic lymph node dissection (ePLND) with regard to distant recurrence-free survival (RFS), according to both main tumour pathological characteristics and number of positive lymph nodes. Biochemical RFS, local RFS, overall survival (OS) and acute and late toxicity were assessed as secondary endpoints. PATIENTS AND METHODS A retrospective cohort of 187 consecutive patients with pN1 PCa were treated with aRT at the IEO, European Institute of Oncology IRCCS, Milan, Italy. aRT on the tumour bed and pelvis was administered within 6 months of RP. Androgen deprivation therapy was administered according to the guidelines. Univariate and multivariate Cox regression analyses predicting biochemical RFS, local RFS, distant RFS and OS rates were performed to assess whether the number of pN1s represented an independent prognostic factor. The Youden index was computed to find the optimal threshold for the number of pN1s able to discriminate between patients with or without biochemical and clinical relapse. RESULTS At 5 years, local RFS, distant RFS, biochemical RFS and OS were 68%, 71%, 56% and 94%, respectively. The median follow-up was 49 months. The number of pN1s was significantly associated with biochemical RFS, local RFS and distant RFS. The best threshold for discriminating between patients with or without biochemical and clinical relapse was five pN1s. In multivariate analyses, the number of pN1s was confirmed to be an independent predictor of biochemical RFS, local RFS and distant RFS, but not of OS. Multivariate analyses also showed an increased risk of biochemical relapse for increasing values of initial prostate-specific antigen and for patients with tumour vascular invasion. Local and distant RFS were also inversely correlated with significantly reduced risk for International Society of Urological Pathology grade group <3 (group 1 or 2 compared to group 3). CONCLUSIONS Our data confirmed the encouraging outcomes of patients with pN1 PCa treated with adjuvant treatments and the key role represented by the number of pN1s in predicting biochemical RFS, clinical RFS and distant RFS. Large prospective cohort studies and randomized clinical trials are needed to confirm these results and to identify the subgroup of patients with pN1 PCa who would most benefit from aRT.

Abstract
Mechanisms of late radio-induced lesions are the result of multiple and complex phenomena, with many entangled cellular and tissue factors. The biological continuum between acute and late radio-induced effects will be described, with firstly a break in homeostasis that leads to cellular redistributions. New insights into late toxicity will finally be addressed. Individual radiosensitivity is a primary factor for the development of late toxicity, and clinicians urgently need predictive tests to offer truly personalized radiation therapy. An update will be made on the various functional and genetic tests currently being validated. The management of radio-induced side effects remains a frequent issue for radiation oncologists, and an update will be made for certain specific clinical situations. Finally, an innovative management for patients with significant side effects after pelvic radiotherapy will be developed, involved mesenchymal stem cell transplantation, with the presentation of the "PRISME" protocol currently open to patients recruitment.
