Abstract
PURPOSE Childhood cancer is rare, and treatment is frequently associated with long-term morbidity. Disparities in survival and long-term side effects encourage the establishment of networks to increase access to complex organ-conservative strategies, such as brachytherapy. We report our experience of an international cooperation model in childhood cancers. METHODS AND MATERIALS We examined the outcome of all children referred to our center from national or international networks to be treated according to a multimodal organ-conservative approach, including brachytherapy. RESULTS We identified 305 patients whose median age at diagnosis was 2.2 years (range, 1.4 months to 17.2 years). Among these patients, 99 (32.4%) were treated between 2015 and 2020; 172 (56.4%) were referred from national centers; and 133 (43.6%) were international patients from 31 countries (mainly Europe). Also, 263 patients were referred for primary treatment and 42 patients were referred for salvage treatment. Genitourinary tumors were the most frequent sites, with 56.4% bladder/prostate rhabdomyosarcoma and 28.5% gynecologic tumors. In addition to brachytherapy, local treatment consisted of partial tumor resection in 207 patients (67.9%), and 39 patients (13%) had additional external radiation therapy. Median follow-up was 58 months (range, 1 month to 48 years), 93 months for national patients, and 37 months for international patients (P < .0001). Five-year local control, disease-free survival, and overall survival rates were 90.8% (95% confidence interval [CI], 87.3%-94.4%), 84.4% (95% CI, 80.1%-89.0%), and 93.3% (95% CI, 90.1%-96.5%), respectively. Patients referred for salvage treatment had poorer disease-free survival (P < .01). Implementation of image guided pulse-dose-rate brachytherapy was associated with better local control among patients with rhabdomyosarcoma referred for primary treatment (hazard ratio, 9.72; 95% CI, 1.24-71.0). At last follow-up, 16.7% patients had long-term severe treatment-related complications, and 2 patients (0.7%) had developed second malignancy. CONCLUSIONS This retrospective series shows the feasibility of a multinational referral network for brachytherapy allowing high patient numbers in rare pediatric cancers. High local control probability and acceptable late severe complication probability could be achieved despite very challenging situations. This cooperation model could serve as a basis for generating international reference networks for high-tech radiation such as brachytherapy to increase treatment care opportunities and cure probability.

Psychological, educational, and social late effects in adolescent survivors of Wilms tumor: A report from the Childhood Cancer Survivor Study. Psychooncology 2020; 30:349-360. [PMID: 33113206 DOI: 10.1002/pon.5584] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2020] [Revised: 08/31/2020] [Accepted: 10/13/2020] [Indexed: 01/01/2023]
Abstract
OBJECTIVE To delineate the impact of treatment exposures and chronic health conditions on psychological, educational, and social outcomes in adolescent survivors of Wilms tumor. METHODS Parent reports from the Childhood Cancer Survivor Study were analyzed for 666 adolescent survivors of Wilms tumor and 698 adolescent siblings. Adjusting for race and household income, survivors were compared to siblings on the Behavior Problems Index and educational outcomes. Multivariable modified Poisson regression estimated relative risks (RR) for therapeutic exposures and chronic health conditions (CTCAE 4.03 graded) among survivors, adjusting for sex, race, income, and age at diagnosis. RESULTS Compared to siblings, adolescent survivors of Wilms tumor were more likely to take psychoactive medication (9.4% vs. 5.1%, p < 0.001) and utilize special education services (25.5% vs. 12.6%, p < 0.001) but did not differ significantly in emotional and behavioral problems. Survivors were less likely to be friendless (7.2% vs. 10.1%, p = 0.04) but were more likely to have difficulty getting along with friends (14.5% vs. 7.8%, p < 0.001). Among survivors, use of special education services was associated with abdomen plus chest radiation (RR = 1.98, CI:1.18-3.34). Those with grade 2-4 cardiovascular conditions had higher risk for anxiety/depression (RR = 1.95, CI:1.19-3.19), headstrong behaviors (RR = 1.91, CI:1.26-2.89), and inattention (RR = 1.56, CI:1.02-2.40). CONCLUSIONS Adolescent survivors of Wilms tumor were similar to siblings with respect to mental health concerns overall but were more likely to require special education. Monitoring of psychosocial and academic problems through adolescence is warranted, especially among those treated with radiation to the abdomen plus chest or with cardiac conditions.

Abstract
In vitro models represent a critical tool in cancer research to study tumor biology and to evaluate new treatment options. Unfortunately, there are no effective preclinical models available that represent Wilms tumor (WT) — the most common pediatric renal tumor. Especially the high-risk blastemal WT subtype is not represented by the few primary cell lines established until now. Here, we describe a new 3D approach for in vitro cultivation of blastemal WT cells, where primary cultures grown in suspension as spheroids could be propagated long-term. Besides blastemal cultures, we could generate spheroids representing epithelial and stromal WT. Spheroid cultures were analyzed by immunohistochemistry in comparison to corresponding tumor sections and were further characterized by RNA sequencing. Histological appearance of spheroids resembled the original tumor and they expressed marker genes characteristic of early renal development and blastemal WT elements. The cultures were amenable to genetic manipulation and they formed xenograft tumors, which resemble the primary human tumor. This collection of WT spheroids that carry different genetic drivers forms a long-sought tool for drug testing and in vitro modeling.

Early and late adverse renal effects after potentially nephrotoxic treatment for childhood cancer. Cochrane Database Syst Rev 2019; 3:CD008944.

Abstract
BACKGROUND Improvements in diagnostics and treatment for paediatric malignancies resulted in a major increase in survival. However, childhood cancer survivors (CCS) are at risk of developing adverse effects caused by multimodal treatment for their malignancy. Nephrotoxicity is a known side effect of several treatments, including cisplatin, carboplatin, ifosfamide, radiotherapy and nephrectomy, and can cause glomerular filtration rate (GFR) impairment, proteinuria, tubulopathy, and hypertension. Evidence about the long-term effects of these treatments on renal function remains inconclusive. It is important to know the risk of, and risk factors for, early and late adverse renal effects, so that ultimately treatment and screening protocols can be adjusted. This review is an update of a previously published Cochrane Review. OBJECTIVES To evaluate existing evidence on the effects of potentially nephrotoxic treatment modalities on the prevalence of renal dysfunction in survivors treated for childhood cancer with a median or mean survival of at least one year after cessation of treatment, where possible in comparison with the general population or CCS treated without potentially nephrotoxic treatment. In addition, to evaluate evidence on associated risk factors, such as follow-up duration, age at time of diagnosis and treatment combinations, as well as the effect of doses. SEARCH METHODS On 31 March 2017 we searched the following electronic databases: CENTRAL, MEDLINE and Embase. In addition, we screened reference lists of relevant studies and we searched the congress proceedings of the International Society of Pediatric Oncology (SIOP) and The American Society of Pediatric Hematology/Oncology (ASPHO) from 2010 to 2016/2017. SELECTION CRITERIA Except for case reports, case series and studies including fewer than 20 participants, we included studies with all study designs that reported on renal function (one year or longer after cessation of treatment), in CCS treated before the age of 21 years with cisplatin, carboplatin, ifosfamide, radiation involving the kidney region, a nephrectomy, or a combination of two or more of these treatments. When not all treatment modalities were described or the study group of interest was unclear, a study was not eligible for the evaluation of prevalence. We still included it for the assessment of risk factors if it had performed a multivariable analysis. DATA COLLECTION AND ANALYSIS Two review authors independently performed study selection, 'Risk of bias' assessment and data extraction using standardised data collection forms. We performed analyses according to the guidelines of the Cochrane Handbook for Systematic Reviews of Interventions. MAIN RESULTS Apart from the remaining 37 studies included from the original review, the search resulted in the inclusion of 24 new studies. In total, we included 61 studies; 46 for prevalence, six for both prevalence and risk factors, and nine not meeting the inclusion criteria, but assessing risk factors. The 52 studies evaluating the prevalence of renal dysfunction included 13,327 participants of interest, of whom at least 4499 underwent renal function testing. The prevalence of adverse renal effects ranged from 0% to 84%. This variation may be due to diversity of included malignancies, received treatments, reported outcome measures, follow-up duration and the methodological quality of available evidence.Seven out of 52 studies, including 244 participants, reported the prevalence of chronic kidney disease, which ranged from 2.4% to 32%.Of these 52 studies, 36 studied a decreased (estimated) GFR, including at least 432 CCS, and found it was present in 0% to 73.7% of participants. One eligible study reported an increased risk of glomerular dysfunction after concomitant treatment with aminoglycosides and vancomycin in CCS receiving total body irradiation (TBI). Four non-eligible studies assessing a total cohort of CCS, found nephrectomy and (high-dose (HD)) ifosfamide as risk factors for decreased GFR. The majority also reported cisplatin as a risk factor. In addition, two non-eligible studies showed an association of a longer follow-up period with glomerular dysfunction.Twenty-two out of 52 studies, including 851 participants, studied proteinuria, which was present in 3.5% to 84% of participants. Risk factors, analysed by three non-eligible studies, included HD cisplatin, (HD) ifosfamide, TBI, and a combination of nephrectomy and abdominal radiotherapy. However, studies were contradictory and incomparable.Eleven out of 52 studies assessed hypophosphataemia or tubular phosphate reabsorption (TPR), or both. Prevalence ranged between 0% and 36.8% for hypophosphataemia in 287 participants, and from 0% to 62.5% for impaired TPR in 246 participants. One non-eligible study investigated risk factors for hypophosphataemia, but could not find any association.Four out of 52 studies, including 128 CCS, assessed the prevalence of hypomagnesaemia, which ranged between 13.2% and 28.6%. Both non-eligible studies investigating risk factors identified cisplatin as a risk factor. Carboplatin, nephrectomy and follow-up time were other reported risk factors.The prevalence of hypertension ranged from 0% to 50% in 2464 participants (30/52 studies). Risk factors reported by one eligible study were older age at screening and abdominal radiotherapy. A non-eligible study also found long follow-up time as risk factor. Three non-eligible studies showed that a higher body mass index increased the risk of hypertension. Treatment-related risk factors were abdominal radiotherapy and TBI, but studies were inconsistent.Because of the profound heterogeneity of the studies, it was not possible to perform meta-analyses. Risk of bias was present in all studies. AUTHORS' CONCLUSIONS The prevalence of adverse renal effects after treatment with cisplatin, carboplatin, ifosfamide, radiation therapy involving the kidney region, nephrectomy, or any combination of these, ranged from 0% to 84% depending on the study population, received treatment combination, reported outcome measure, follow-up duration and methodological quality. With currently available evidence, it was not possible to draw solid conclusions regarding the prevalence of, and treatment-related risk factors for, specific adverse renal effects. Future studies should focus on adequate study designs and reporting, including large prospective cohort studies with adequate control groups when possible. In addition, these studies should deploy multivariable risk factor analyses to correct for possible confounding. Next to research concerning known nephrotoxic therapies, exploring nephrotoxicity after new therapeutic agents is advised for future studies. Until more evidence becomes available, CCS should preferably be enrolled into long-term follow-up programmes to monitor their renal function and blood pressure.

Abstract
INTRODUCTION The long-term survival of a patient with childhood cancer now exceeds 80%. Unfortunately, as survivorship improves, the long-term consequences of the treatments used have become manifest. Specifically, the finding that development of a subsequent malignant neoplasm (SMN) is the leading cause of late mortality is concerning. In cancer survivors who are at high risk for developing an SMN, cancer screening protocols have well-documented survivorship benefits. Regrettably, 50% of these high-risk patients are non-compliant with these protocols, with studies revealing that inadequate patient compliance is in part because of insufficient knowledge of the physician regarding its need. DISCUSSION Urologists are in a unique position to correct this deficiency. Characteristically, survivors of childhood cancer present to urologists as an adult with complaints of infertility, erectile dysfunction, androgen deprivation, lower urinary tract symptoms or for follow-up of a urinary diversion. The urologist because of their specialty should be able to treat the patients presenting complaint, identify the high-risk patient, and re-establish them on their surveillance protocol. SCREENING RECOMMENDATIONS FOR HIGH-RISK PATIENTS The risk for developing an SMN is unequally expressed and is temporally biphasic. A minimal 10-year follow-up time span is recommended for patients who received alkylating agents or topoisomerase inhibitors. These agents can induce hematologic malignancies classically within the first 3-5 years after chemotherapy completion, with minimal risk existing after 10 years. Lifelong follow-up for SMN development is recommended under five distinct circumstances; if a genetic predisposition to tumor formation exists, a persistent post-treatment non-malignant mass is present if chemotherapy was received before 2 years of age, if the initial type of tumor predisposes to SMN, or if the patient received radiation therapy. CONCLUSION The urologists ability to identify the patient at high risk for developing an SMN and return them to a surveillance protocol is crucial for appropriate patient management.

Abstract
PURPOSE OF REVIEW Over 80% of children diagnosed with cancer are now cured. The burgeoning population of survivors of childhood cancer experiences high rates of morbidity and mortality due to 'late-effects' of treatment. These can be defined as any consequence of treatment that persists beyond or develops after the completion of cancer therapy. Awareness of late-effects is critically important for pediatricians and adult providers alike, as late-effects impact children in proximity to cancer treatment, as well as adults many decades removed. This review presents the importance of lifelong follow-up care for survivors, highlights existing screening guidelines, and reviews various models of survivor care. RECENT FINDINGS National and international guidelines have been developed to standardize screening for survivors, and multiple models of survivorship care exist. The optimal model likely depends on individual factors, including the survivor's needs and preferences, as well as local resources. Key strategies for the successful care of survivors include accurate risk-stratification for specific late-effects, individualized screening plans, education of survivors and professionals, clear communication between providers, and well coordinated transition of care across services. SUMMARY Early identification and management of late-effects are important for survivors of childhood cancer. Providers should be familiar with the risks for specific late-effects and have access to screening guidelines. The strengths and weaknesses of care models, along with individual circumstances, should be considered in designing the optimal approach to care for each survivor.

Abstract
Advances in the management of Wilms' tumor have been dramatic over the past half century, not in small part due to the institution of multimodal therapy and the formation of collaborative study groups. While different opinions exist in the management of Wilms' tumors depending on where one lives and practices, survival rates have surpassed 90% across the board in Western societies. With more children surviving into adulthood, the concerns about morbidity have reached the forefront and now represent as much a consideration as oncologic outcomes these days. Innovations in treatment are on the horizon in the form of potential tumor markers, molecular biological means of testing for chemotherapeutic responsiveness, and advances in the delivery of chemotherapy for recurrent or recalcitrant tumors. Other technological innovations are being applied to childhood renal tumors, such as minimally invasive and nephron-sparing approaches. Risk stratification also allows for children to forego potentially unnecessary treatments and their associated morbidities. Wilms' tumor stands as a great example of the gains that can be made through protocol-driven therapy with strenuous outcomes analyses. These gains continue to spark interest in minimization of morbidity, while avoiding any compromise in oncologic efficacy. While excitement and innovation are important in the advancement of treatment delivery, we must continue to temper this enthusiasm and carefully evaluate options in order to continue to provide the highest standard of care in the management of this now highly curable disease.

Abstract
Introduction Bloom syndrome is a rare, autosomal recessive, chromosomal instability disorder caused by mutations in the BLM gene that increase the risk of developing neoplasias, particularly lymphomas and leukemias, at an early age. Case presentation Case 1 was a 10-year-old Brazilian girl, the third child of a non-consanguineous non-Jewish family, who was born at 36 weeks of gestation and presented with severe intrauterine growth restriction. She had Bloom syndrome and was diagnosed with a unilateral Wilms’ tumor at the age of 3.5 years. She responded well to oncological treatment and has remained disease-free for the last 17 years. Case 2 was a 2-year-old Brazilian girl born to non-Jewish first-degree cousins. Her gestation was marked by intrauterine growth restriction. She had Bloom syndrome; a unilateral stage II Wilms’ tumor was diagnosed at the age of 4 years after the evaluation of a sudden onset abdominal mass. Surgical removal, neoadjuvant chemotherapy and radiotherapy were not sufficient to control the neoplasia. The tumor recurred after 8 months and she died from clinical complications. Conclusion Our study reports the importance of rapid diagnostics and clinical follow-up of these patients.

Abstract
Tumors of the kidney, bladder, prostate, testis, and adrenal represent a large part of the adult urologic practice, but are relatively infrequent in children. The natural history and management of these tumors in the pediatric age is different from that of the adults. As result of the successful work of several clinical trial groups in recent decades, there has been a significant improvement in their cure rates. The aim of this article is to review their most significant clinical aspects, as well as to present an update in their management.

Portal Hypertension in Childhood Bilateral Wilms' Tumor Survivor: An Excellent Indication for TIPS. Case Rep Gastrointest Med 2013; 2013:523154. [PMID: 23653866 PMCID: PMC3638574 DOI: 10.1155/2013/523154] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/13/2013] [Accepted: 03/17/2013] [Indexed: 11/17/2022] Open
Abstract
Introduction. Increased pressure in portal venous system is relatively a rare complication after chemoradiotherapy for Wilms' tumor (WT). In paediatric population, feasibility and efficacy of transjugular intrahepatic portosystemic shunt (TIPS) in portal hypertension nonresponsive to medical or endoscopic treatment have been recently advocated. We report a case of TIPS positioning in a 15-year-old girl with portal hypertension as a long-term sequel of multimodality therapy in bilateral WT. Case Report. Two-year-old girl was diagnosed for bilateral WT. Right nephrectomy with left heminephrectomy and chemoradiotherapy were performed. At 7 years of age, the first gastrointestinal bleeding appeared, followed by another episode two years later, both were treated successfully with beta-blockers. At 15 years of age, severe unresponsive life-threatening gastroesophageal bleeding without hepatosplenomegaly was managed by TIPS. Reduction of the portosystemic pressure gradient was obtained. Conclusion. TIPS positioning for portal hypertension in long-term tumors' sequel is feasible and could be considered as an additional indication in paediatric patients.
