Nanda RH, Hua CH, Flampouri S, Eaton B, Kaste S, Patni T, Ronckers C, Constine LS, Marks LB, Esiashvili N. Risks of Spinal Abnormalities and Growth Impairment After Radiation to the Spine in Childhood Cancer Survivors: A PENTEC Comprehensive Review. Int J Radiat Oncol Biol Phys 2024; 119:507-521. [PMID: 38069918 DOI: 10.1016/j.ijrobp.2023.10.039] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Revised: 10/03/2023] [Accepted: 10/22/2023] [Indexed: 05/19/2024]
Abstract
PURPOSE A PENTEC (Pediatric Normal Tissue Effects in the Clinic) review was performed to estimate the dose-volume effects of radiation therapy on spine deformities and growth impairment for patients who underwent radiation therapy as children. METHODS AND MATERIALS A systematic literature search was performed to identify published data for spine deformities and growth stunting. Data were extracted from 12 reports of children irradiated to the spine (N = 603 patients). The extracted data were analyzed to find associations between complication risks and the radiation dose (conventional fractionation throughout) as impacted by exposed volumes and age using the mixed-effects logistic regression model. When appropriate, corrections were made for radiation modality, namely orthovoltage beams. RESULTS In the regression analysis, the association between vertebral dose and scoliosis rate was highly significant (P < .001). Additionally, young age at time of radiation was highly predictive of adverse outcomes. Clinically significant scoliosis can occur with doses ≥15 Gy to vertebrae during infancy (<2 years of age). For children irradiated at 2 to 6 years of age, overall scoliosis rates of any grade were >30% with doses >20 Gy; grade 2 or higher scoliosis was correlated with doses ≥30 Gy. Children >6 years of age remain at risk for scoliosis with doses >30 Gy; however, most cases will be mild. There are limited data regarding the effect of dose gradients across the spine on degree of scoliosis. The risk of clinically meaningful height loss was minimal when irradiating small volumes of the spine up to 20 Gy (eg, flank irradiation), except in infants who are more vulnerable to lower doses. Growth stunting was more frequent when larger segments of the spine (eg, the entire spine or craniospinal irradiation) were irradiated before puberty to doses >20 Gy. The effect was modest when patients were irradiated after puberty to doses >20 Gy. CONCLUSIONS To reduce the risk of kyphoscoliosis and growth impairment, the dose to the spine should be kept to <20 Gy for children <6 years of age and to <10 to 15 Gy in infants. The number of vertebral bodies irradiated and dose gradients across the spine should also be limited when possible.

Reporting Standards for Complication Studies of Radiation Therapy for Pediatric Cancer: Lessons From PENTEC. Int J Radiat Oncol Biol Phys 2024; 119:697-707. [PMID: 38760117 DOI: 10.1016/j.ijrobp.2024.02.018] [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: 07/08/2023] [Revised: 01/14/2024] [Accepted: 02/08/2024] [Indexed: 05/19/2024]
Abstract
The major aim of Pediatric Normal Tissue Effects in the Clinic (PENTEC) was to synthesize quantitative published dose/-volume/toxicity data in pediatric radiation therapy. Such systematic reviews are often challenging because of the lack of standardization and difficulty of reporting outcomes, clinical factors, and treatment details in journal articles. This has clinical consequences: optimization of treatment plans must balance between the risks of toxicity and local failure; counseling patients and their parents requires knowledge of the excess risks encountered after a specific treatment. Studies addressing outcomes after pediatric radiation therapy are particularly challenging because: (a) survivors may live for decades after treatment, and the latency time to toxicity can be very long; (b) children's maturation can be affected by radiation, depending on the developmental status of the organs involved at time of treatment; and (c) treatment regimens frequently involve chemotherapies, possibly modifying and adding to the toxicity of radiation. Here we discuss: basic reporting strategies to account for the actuarial nature of the complications; the reporting of modeling of abnormal development; and the need for standardized, comprehensively reported data sets and multivariate models (ie, accounting for the simultaneous effects of radiation dose, age, developmental status at time of treatment, and chemotherapy dose). We encourage the use of tools that facilitate comprehensive reporting, for example, electronic supplements for journal articles. Finally, we stress the need for clinicians to be able to trust artificial intelligence models of outcome of radiation therapy, which requires transparency, rigor, reproducibility, and comprehensive reporting. Adopting the reporting methods discussed here and in the individual PENTEC articles will increase the clinical and scientific usefulness of individual reports and associated pooled analyses.

Abstract
The use of curative-intent multimodality therapy with chemotherapy, surgery, and radiation results in late toxicities in almost two-thirds of patients with pediatric cancer. When pelvic radiation is used for pediatric malignancies such as rhabdomyosarcoma, lymphoma, neuroblastoma, Ewing sarcoma, and Wilms tumor, the associated late toxicities can affect many normal tissues and may include growth asymmetries, cystitis, infertility, and sexual dysfunction. We describe 4 recommendations of how to prevent or minimize late toxicities from pelvic radiation and review the literature of these pediatric late toxicities.

Abstract
Advances in multimodality therapy have led to childhood cancer cure rates over 80%. However, surgery, chemotherapy, and radiotherapy may lead to debilitating or even fatal long-term effects among childhood survivors beyond those inflicted by the primary disease process. It is critical to understand, mitigate, and prevent these late effects of cancer therapy to improve the quality of life of childhood cancer survivors. This review summarizes the various late effects of radiotherapy and acknowledges the Pediatric Normal Tissue Effects in the Clinic (PENTEC), an international collaboration that is systematically analyzing the association between radiation treatment dose/volume and consequential organ toxicities, in developing children as a basis to formulate recommendations for clinical practice of pediatric radiation oncology. We also summarize initiatives for survivorship and surveillance of late normal tissue effects related to radiation therapy among long-term survivors of childhood cancer treated in the past.

An Analysis of Vertebral Body Growth after Proton Beam Therapy for Pediatric Cancer. Cancers (Basel) 2021; 13:cancers13020349. [PMID: 33477867 PMCID: PMC7832908 DOI: 10.3390/cancers13020349] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2020] [Revised: 01/13/2021] [Accepted: 01/15/2021] [Indexed: 12/03/2022] Open
Abstract
Simple Summary Radiotherapy has a key role in treatment of pediatric cancer and has greatly improved survival in recent years. However, vertebrae are often included in the irradiated area, and this may affect growth after treatment. In this study, we examined the relationship of the dose of proton beam therapy with subsequent growth of 353 vertebral bodies in 23 children (10 boys, 13 girls) with a median age at treatment of 4 years old and a median observation period of 13.9 months. Most importantly, we found that the growth rate of vertebral bodies decreased even at a low proton beam therapy dose, which indicates the need for careful planning of the irradiation area in this patient population. Growth inhibition was clearly dose-dependent, and proton beam therapy had the same growth inhibitory effect as photon radiotherapy, at least within the irradiated field. Abstract Impairment of bone growth after radiotherapy for pediatric bone cancer is a well-known adverse event. However, there is limited understanding of the relationship between bone growth and irradiation dose. In this study, we retrospectively analyzed bone growth impairment after proton beam therapy for pediatric cancer. A total of 353 vertebral bodies in 23 patients under 12 years old who received proton beam therapy were evaluated. Compared to the non-irradiated vertebral body growth rate, the irradiated vertebral body rate (%/year) was significantly lower: 77.2%, 57.6%, 40.8%, 26.4%, and 14.1% at 10, 20, 30, 40, and 50 Gy (RBE) irradiation, respectively. In multivariate analysis, radiation dose was the only factor correlated with vertebral body growth. Age, gender, and vertebral body site were not significant factors. These results suggest that the growth rate of the vertebral body is dose-dependent and decreases even at a low irradiated dose. This is the first report to show that proton beam therapy has the same growth inhibitory effect as photon radiotherapy within the irradiated field.

Abstract
Haematopoietic stem cell transplant (HSCT) can be a curative treatment for children and adolescents with very-high-risk acute lymphoblastic leukaemia (ALL). Improvements in supportive care and transplant techniques have led to increasing numbers of long-term survivors worldwide. However, conditioning regimens as well as transplant-related complications are associated with severe sequelae, impacting patients' quality of life. It is widely recognised that paediatric HSCT survivors must have timely access to life-long care and surveillance in order to prevent, ameliorate and manage all possible adverse late effects of HSCT. This is fundamentally important because it can both prevent ill health and optimise the quality and experience of survival following HSCT. Furthermore, it reduces the impact of preventable chronic illness on already under-resourced health services. In addition to late effects, survivors of paediatric ALL also have to deal with unique challenges associated with transition to adult services. In this review, we: (1) provide an overview of the potential late effects following HSCT for ALL in childhood and adolescence; (2) focus on the unique challenges of transition from paediatric care to adult services; and (3) provide a framework for long-term surveillance and medical care for survivors of paediatric ALL who have undergone HSCT.

Local Stage Dependent Necessity of Radiation Therapy in Rhabdoid Tumors of the Kidney (RTK). Int J Radiat Oncol Biol Phys 2020; 108:667-675.

Abstract
PURPOSE Rhabdoid tumor of the kidney (RTK) is one of the most aggressive childhood renal tumors. Overall survival ranges from 22% to 47%. The indication for radiation therapy (RT) in usually very young patients is an ongoing discussion. Recent protocols recommend RT independent of local stage, the latter being a good discriminator in other childhood kidney tumors. In this study, we analyze the evidence for RT in regard to risk factors, including tumor stage. METHODS AND MATERIALS This study analyzed 58 patients with RTK from Austria, Switzerland, and Germany treated in the framework of 4 consecutive, prospective renal/rhabdoid tumor studies from 1991 to 2014. All treatment protocols included multimodality treatment, including high-intensity chemotherapy, surgery, and RT. RESULTS Local stage distribution was not applicable, I, II, and III in 1, 6, 11, and 40, respectively. Twenty-nine (50%) patients had stage IV disease at diagnosis. Thirty-seven patients (64%) achieved complete remission, and 49% (18/37) relapsed. Thirty-four patients (60%) patients had progressive disease and died, 17 had local disease, 10 had combined disease, and 7 had distant disease; 2 treatment-related deaths were reported (3%). Twenty-one patients received RT during first-line treatment, 18 of them to all involved sites. Eight of the 34 cases of progressive disease occurred in irradiated patients. The local failure rate of treated patients with local stage II or III disease was 29% (6/18) in patients irradiated to all sites compared with 68% (15/22) in nonirradiated patients. One of 6 stage I patients received RT, and 1 patient experienced distant relapse (2-year progression-free and overall survival both 83% ± 15%). Progression-free survival for local stage II and III disease treated with RT, adjusted for early relapse or treatment abandonment, was 67% ± 11%, compared with 15% ± 7% without RT (P < .0001). CONCLUSION The 68% local failure rate in nonirradiated patients underlines the importance of local treatment. Our experience supports the use of RT for local control in higher stage disease. In contrast, no local relapse in 6 local stage I patients, including 5 nonirradiated patients, suggests omission of RT in this favorable subset of usually infant patients with RTK.

Abstract
Background The role of local radiotherapy in the treatment of metastatic rhabdomyosarcoma is important. However, with peritoneal dissemination, the application of local therapy is challenging. Although there are few reports addressing the efficacy of the whole abdominopelvic irradiation to peritoneal disseminated rhabdomyosarcoma patients, no precise curse of treatment nor the follow up result is explained in paper nor in the text. Case presentation Six years old rhabdomyosarcoma boy with peritoneal dissemination was treated at our facility under COG D9803 protocol (vincristine, dactinomycin, and cyclophosphamide (VAC)). He underwent tumor resection on the 14th week according to the protocol. During surgery, the 2-cm residual tumor was completely resected, but in the pelvis, numerous nodules that were suspected as peritoneal disseminated tumors were observed. We administered 30 Gy/20fr whole abdominopelvic radiotherapy using volumetric modulated arc therapy (VMAT) technique and a 6 Gy sequential boost to pelvis after the surgery and completed the protocol treatment. During the course of treatment, the patient experienced G4 hematological toxicity and received multiple transfusions, particularly after whole abdominopelvic irradiation. He has achieved complete remission and is alive without evidence of recurrence and severe late adverse effect for 3 years. In terms of growth, his height and weight are within the average values for Japanese boys at the same age. Conclusion By using the VMAT technique, a patient with peritoneal disseminated rhabdomyosarcoma can be treated, and a dose of 30 Gy to the whole abdominopelvis with concurrent chemotherapy may be tolerable.

Abstract
With the increasing use of advanced radiation techniques such as intensity modulated radiation therapy, stereotactic radiation therapy, and proton therapy, radiation oncologists now have the tools to mitigate radiation-associated toxicities. This is of utmost importance in the treatment of a pediatric patient. To best use these advanced techniques to mitigate radiation-induced growth abnormalities, the radiation oncologist should be equipped with a nuanced understanding of the anatomy of centers of growth. This article aims to enable the radiation oncologist to better understand, predict, and minimize radiation-mediated toxicities on growth. We review the process of bone development and radiation-induced growth abnormalities and provide an atlas for contouring important growth plates to guide radiation treatment planning. A more detailed recognition of important centers of growth may improve future treatment outcomes in children receiving radiation therapy.

[PMID: 29693799 DOI: 10.1002/pbc.27085] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/08/2017] [Revised: 02/22/2018] [Accepted: 03/13/2018] [Indexed: 11/08/2022]
Abstract
OBJECTIVE To evaluate the value of radiotherapy boost omission in patients with intermediate-risk, stage III Wilms tumours (WT) with positive lymph nodes (LN). METHODS AND MATERIALS All patients with intermediate-risk, stage III (LN positive) WT consecutively registered in the SIOP-WT-2001 study were included in this analysis. Endpoints were 5-year event-free survival (EFS), loco-regional control (LRC) and overall survival (OS). RESULTS Between June 2001 and May 2015, 2,569 patients with stage I to III WT after preoperative chemotherapy were registered in the SIOP-WT-2001 study. Five hundred and twenty-three (20%) had stage III disease, of which 113 patients had stage III due to positive LN only. Of those, 101 (89%) received radiotherapy, 36 of which (36%) received, apart from flank irradiation, a boost dose to the LN positive area. Four patients (4%) did not receive any adjuvant radiotherapy. In eight patients information on radiotherapy was not available. With a median follow-up of 71 months, no difference in 5-year EFS (84% vs. 83%, P = 0.77) and LRC (96% vs. 97%, P = 0.91) was observed between patients receiving a radiotherapy boost and those without boost, respectively. Five-year OS, including salvage therapy, was excellent (boost vs. no boost: 97% vs. 95%, P = 0.58). CONCLUSIONS Outcome data demonstrate that omission of the radiotherapy boost to the loco-regional positive lymph nodes in patients with intermediate-risk, stage III WT who receive preoperative chemotherapy and postoperative flank irradiation (14.4 Gy) can be considered a safe approach for future SIOP protocols.

Abstract
OBJECTIVE Here, we report musculoskeletal outcomes and the impact of radiotherapy dose on vertebral body growth for an institutional series of long-term survivors of high-risk neuroblastoma. METHODS We conducted a retrospective study of 23 patients who were disease-free and at least 36 months from the end of treatment. The patients were initially treated from July 2003 to May 2012. Patient records were reviewed for growth percentiles (obtained at approximately 6-month intervals from onset of treatment to the last follow-up) and musculoskeletal comorbidities. RT plans and most recent surveillance CT scans were reviewed for locations of in-field vertebral bodies and corresponding vertebral growth patterns. RESULTS The median follow-up was 7.93 years. The median prescribed radiation dose was 21.6 Gy. Musculoskeletal abnormalities included scoliosis (5 patients), muscular hypoplasia (3), and hypodontia (1). The median growth percentile at treatment onset was 35.5 (range, 4.7-100) versus 10 (0-94.1) at the last follow-up. The median numbers of vertebral bodies encompassed (by at least half of their volume) by the 5-, 10-, 15-, and 20-Gy isodose lines were 7 (mean, 6.78), 7 (6.56), 6 (6.17), and 6 (5.52), respectively. Sixteen patients (70.0%) had in-field abnormalities in vertebral body growth, manifesting as stretches of successive vertebral bodies at the same height, while normally there is a gradual vertebral body height increase progressing caudally down the spinal column. CONCLUSIONS Musculoskeletal abnormalities, below average height, and stunted in-field vertebral body growth are routine in long-term survivors of high-risk neuroblastoma. Sparing vertebral bodies when feasible may lead to improvement in patient growth trajectories.

Abstract
BACKGROUND Craniospinal irradiation (CSI) is the standard radiation therapy treatment for medulloblastoma. Conventional CSI photon therapy (Photon-CSI) delivers significant dose to surrounding normal tissue (NT). Research into pediatric CSI with proton therapy (Proton-CSI) has increased, with the aim of exploiting the potential to reduce NT dose and associated post-treatment complications. This review aims to compare treatment outcomes of pediatric medulloblastoma patients between Proton- and Photon-CSI treatments. MATERIAL AND METHODS A search and review of studies published between 1990 and 2016 comparing pediatric (2-18 years) medulloblastoma Proton- and Photon-CSI in three aspects - normal organ sparing and target coverage; normal organ dysfunction and second malignancy risks - was completed. RESULTS Fifteen studies were selected for review and the results were directly compared. Proton-CSI reported improved out-of-field organ sparing while target coverage improvements were inconsistent. Normal organ dysfunction risks were predicted to be lower following Proton-CSI. Secondary malignancy risks (SMRs) were generally lower with Proton-CSI based on several different risk models. CONCLUSIONS Proton-CSI conferred better treatment outcomes than Photon-CSI for pediatric medulloblastoma patients. This review serves to compare the current literature in the absence of long-term data from prospective studies.

Abstract
Bleeding into joint space is critical to develop hemophilic arthropathy. To reduce the frequency of bleeding in the ankle joint of children with hemophilic arthropathy, low dose external beam irradiation was performed for 37 patients. Among them, 35 patients followed-up for longer than 1 yr (median 87 months) were enrolled for analysis. The average number of bleedings per month was 3.6 during one year prior to radiation therapy. After radiation therapy, it was decreased to 2.1 during the first year, after then it was maintained in the range of 1.0 to 1.5 until the tenth year. The bleeding frequency was reduced to 42% at the first year and it was maintained in the range of 58% to 73% from the second to the tenth year. Especially the patients who had 3 or more bleedings per month, and who had MRI score more than 3 showed significant decreases. During the follow-up period, growth disturbances and secondary malignancies were not found. External beam radiotherapy can be considered for the hemophilic patients with surgical or isotope therapies are not amenable.

Abstract
BACKGROUND We report the radiation-induced late morbidity observed in our prospective series of Wilms tumor patients treated at the Second University of Naples. METHODS From April 1981 to April 2000, 98 patients were referred at our institution for treatment of Wilms tumor. Among them, 51 underwent radiotherapy and 34 patients had a minimum follow-up of 5 years. Doses of irradiation and treatment portals were those recommended by the guidelines of the Italian Association of Haematology and Paediatric Oncology according to risk stratification. All eligible patients were reviewed for follow-up every 6 months. Median follow-up was 181 months (range 60 to 264 months). RESULTS Eleven out of 34 patients (32%) did not suffer from any significant late side effect. Out of the remaining 23 (68%), 14 (41%) suffered from scoliosis presenting between 60 and 180 months from completion of treatment. Muscular hypoplasia, length inequality, kyphosis, and iliac wing hypoplasia were seen respectively, in 4 (12%), 4 (12%), 5 (15%), and 3 (9%) patients. The incidence of intestinal occlusion was 20%. One patient had chronic renal insufficiency. Four out of 13 female patients reported ovarian failure. Three out of the 7 patients who had radiotherapy to the lung developed radiation-pneumonitis. Radiation-induced heart disease was seen in 3 (9%) patients. Three patients (9%) suffered from second malignancies arising within the irradiated volume. CONCLUSIONS Our data confirm the high incidence of late radiation morbidity in patients undergoing adjuvant radiotherapy for Wilms tumor. For most organ systems there is a correlation between total dose, morbidity rates, and degree of severity.

Abstract
OBJECTIVE The effectiveness and limitations of spinal radiosurgery using a helical TomoTherapy system for the treatment of spinal metastases are reviewed in this article. METHODS This is a retrospective review of patients who underwent stereotactic radiosurgery for spinal metastases between July 2004 and December 2007. Radiographic follow-up consisted of magnetic resonance imaging to assess tumor growth control as well as pre- and posttreatment x-rays, which were used to measure changes in segmental angulation and deformity. Clinical performance was assessed using the Karnofsky Performance Scale, Oswestry Disability Index, and visual analog scale. RESULTS Forty patients were treated for 110 metastatic tumors (range, 1-6 tumors per patient). The mean age at the time of radiosurgical treatment was 67 years (age range, 35-81 years). Twenty-three patients (57.5%) had undergone previous surgical resection. Pain was the most common presenting symptom, seen in 32 patients (80%). The mean Oswestry Disability Index score at presentation was 43 (range, 20-90), and the mean visual analog scale score was 6.2 (range, 0-10). The mean radiosurgical dose to the tumor was 17.3 Gy (range, 10-24 Gy). At a mean follow-up duration of 12.7 months (range, 4-32 months), decreased or stable tumor volume was seen in 90 (82%) of the tumors treated. There was improvement in pain in 34 patients (85%). The mean postradiosurgical Oswestry Disability Index score was 25 (range, 10-90), whereas the postradiosurgical visual analog scale score was 3.2 (range, 0-9). Progression of kyphosis was the most common radiographic sequela, experienced by 73% of patients alive at 12 months, with a mean change in angulation of 7.3 +/- 4.5 degrees. CONCLUSION Radiosurgery is effective as either primary or adjunctive treatment of metastatic tumors of the spine.

Intraoperative spillage of favorable histology wilms tumor cells: influence of irradiation and chemotherapy regimens on abdominal recurrence. A report from the National Wilms Tumor Study Group. Int J Radiat Oncol Biol Phys 2010; 76:201-6. [PMID: 19395185 DOI: 10.1016/j.ijrobp.2009.01.046] [Citation(s) in RCA: 35] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2008] [Revised: 01/26/2009] [Accepted: 01/28/2009] [Indexed: 11/23/2022]
Abstract
PURPOSE We undertook this study to determine (1) the frequency with which spilled tumor cells of favorable histology produced intra-abdominal disease in patients treated with differing chemotherapy regimens and abdominal radiation therapy (RT) and (2) the patterns of relapse and outcomes in such patients. METHODS AND MATERIALS The influence of RT dose (0, 10, and 20 Gy), RT fields (flank, whole abdomen), and chemotherapy with dactinomycin and vincristine (2 drugs) vs. added doxorubicin (three drugs) on intra-abdominal tumor recurrence rates was analyzed by logistic regression in 450 patients. Each patient was considered at risk for two types of failure: flank and subdiaphragmatic beyond-flank recurrence, with the correlation between the two outcomes accounted for in the analyses. RESULTS The crude odds ratio for the risk of recurrence relative to no RT was 0.35 (0.15-0.78) for 10Gy and 0.08 (0.01-0.58) for 20Gy. The odds ratio for the risk of recurrence for doxorubicin to two drugs after adjusting for RT was not significant. For Stage II patients (NWTS-4), the 8-year event rates with and without spillage, respectively, were 79% and 87% for relapse-free survival (p = 0.07) and 90% and 95% for overall survival (p = 0.04). CONCLUSIONS Irradiation (10 Gy or 20 Gy) reduced abdominal tumor recurrence rates after tumor spillage. Tumor spillage in Stage II patients reduced relapse-free survival and overall survival, but only the latter was of statistical significance. These data provide a basis for assessing the risks vs. benefits when considering treatment for children with favorable histology Wilms tumor and surgical spillage.

Abstract
PURPOSE Wilms' tumor is the most common renal tumor in children. Outcomes have improved dramatically over the past few decades, but important treatment questions remain. These include the role of molecular biologic markers in stratifying patients for therapy or targeting tumors for treatment. We present a summary of these advances and outline the current treatment of Wilm's tumor. MATERIALS AND METHODS The medical literature and results of all cooperative group studies reporting treatment of children with Wilms' tumor were reviewed. RESULTS Overall survival exceeds 90% for most patients with nephroblastoma. However, outcomes for patients with rhabdoid tumors and diffuse anaplasia remain poor. The role of renal sparing surgery in patients with bilateral tumors is clear, but for children with unilateral tumors it continues to be defined. CONCLUSIONS Current protocols conducted by pediatric oncology groups are beginning to incorporate biologic features to stratify patients for therapy. Treatment strategies continue to focus on limiting late effects of treatment while maintaining an excellent survival. New therapies are needed to treat the high-risk patients who continue to have high relapse and mortality rates.

Abstract
The immense progress made in childhood cancer survival has been due to the systematic and efficient conduct of large multicenter therapeutic trials, using the infrastructure developed by national cooperative groups. These therapeutic trials have been successful, in part due to the high participation rates by the participating member institutions. However, participation in nontherapeutic trials in the cooperative group setting has lagged behind that of therapeutic trials for a variety of reasons, such as lack of institutional resources, leading to low priority given to such activities. The purpose of this report is to share some of the methods developed and successfully implemented by a coordinating center (City of Hope National Medical Center) to maximize institutional participation and patient enrollment and to standardize data collection and quality control, in order to ensure the successful execution of two large, extramurally funded, cooperative group nontherapeutic studies. To date, over 175 institutions have obtained regulatory approval for the protocols showcased here, accrual has been on target, and completeness and quality of the collected data have been excellent. The successful execution of these nontherapeutic studies shows the advantages of diverse study publicity techniques, detailed standardized operating procedures, and effective utilization of technological resources.

Abstract
BACKGROUND Long-term survivors of Wilms tumor and neuroblastoma may experience significant late adverse effects from their disease and its therapy. Little is known, however, about the health-related quality of life experienced by these survivors. PROCEDURE Health-related quality of life, measured by the 36-Item Short Form Health Survey (SF-36), was assessed from self-report in adult survivors of Wilms tumor (N = 654) and neuroblastoma (N = 432) who participated in the Childhood Cancer Survivor Study. RESULTS More than 90% of the study population was 18-34 years old at interview, and 58% were females. There was no significant difference on any SF-36 subscale or summary scale between the two diagnostic groups. On average, survivors reported no decrement on the Physical Component Summary scale of the SF-36 when compared to population norms. However, both groups scored significantly below the population mean score (50) on the Mental Component Summary Scale of the SF-36 (Wilms tumor mean = 41.66, standard error = 2.19, P < 0.0001; neuroblastoma mean = 42.41, standard error = 2.23, P < 0.0001) reflecting decreased emotional health. Independent risk factors for lower scores on this scale included female gender, Native American race, unemployment, and household income below $20,000. CONCLUSIONS Adult survivors of childhood Wilms tumor and neuroblastoma do not differ from population norms on most health-related quality of life (HRQL) measures. These data, however, indicate that the emotional well being of adult survivors may be compromised. Health care providers should be aware of the risk of adverse outcomes in emotional health even many years after treatment and cure.

Abstract
As more patients are treated for their primary malignancy with cure or increased disease-free intervals, injury to normal tissues will become more detectable and an important endpoint for study. Future protocols will probably be modified based on toxicity endpoints. In Hodgkin's disease, current protocols use response-based treatment strategies to limit therapy. The objective is to provide the same level of tumor control and follow normal tissue endpoints for outcome analysis. DVH analysis has improved the ability to analyze endpoint data for normal tissues. These image-guided platforms will provide the infrastructure needed to continue efforts in improving the delivery of radiation therapy.

Abstract
Improvement in survival after childhood cancer has resulted in a growing population of childhood cancer survivors, causing the healthcare community to focus on providing appropriate care to the survivors, and addressing issues related to the etiology and prevention of long-term sequelae of cancer and its treatment. The overarching goal is to decrease the morbidity related to cancer treatment, and improve the overall quality of life, such that cancer survivors can successfully integrate back into society and lead productive lives. In order to achieve this goal, several issues need to be addressed, such as education of survivors and healthcare providers regarding the potential late effects; provision of standardized guidelines for appropriate follow-up of the survivors in a setting that is feasible and practical for the cancer survivor; ongoing communication between the cancer center that provided acute care for the patient and the healthcare facility providing follow-up care. Several challenges remain in addressing these issues, and will be the focus of this article.

Abstract
BACKGROUND Recent Wilms' tumor (WT) trials and studies have tried to determine the minimal therapy needed for cure. The goal was survival without morbidity. PATIENTS AND METHODS From January 1989 to March 1994 the German Society of Pediatric Oncology and Hematology registered 440 patients (median age 2.9 years; 231 male, 209 female) with WTs (preoperative chemotherapy 362) for therapy according to the International Society of Pediatric Oncology Trial and Study 9. Therapy for relapse depended on site of relapse and therapy already received. Follow-up included inquiries for morbidity. Prognostic factors for relapse and death were evaluated. RESULTS Five-year survival of WTs was 89.5%; 98.2% (385 of 392) of survivors had a follow-up of 5 years (range 0.8-12.6; median 8). In non-anaplastic WTs, young age (<2 years) was of significance (P = 0.026) for a better survival. Non-anaplastic WTs (407 patients) had a 5-year survival of 92.3%, versus 48.5% in anaplastic WTs (33 patients), and a 5-year relapse-free survival of 87.6% versus 42.4%. Survival after relapse was significantly worse for anaplastic than for non-anaplastic WTs (residual 3-year survival 11.8% versus 54.3%; P <0.0001). In preoperatively treated WTs, anaplasia was a strong prognostic factor for death [relative risk (RR) 4.7], followed by poor response to preoperative therapy (RR 3.6), stage IV (RR 3.2) and abdominal stage III (RR 2.2). Low abdominal stages (<III) dominated (280 versus 82). In the 334 unilateral stage I-IV WTs (median age 3.2 years), diffuse anaplasia (21 patients) had a 5-year relapse-free survival of 38.1%, versus 58.4% in blastemal WTs (25 patients); survival was 42.9% in diffuse anaplasia versus 84% in blastemal WTs. None of 46 patients (median age 1.9 years; 91.3% stages I or II) with differentiated WTs (nine epithelial, 37 stromal) relapsed despite their non-response; two died (one therapy related, one due to bilaterization). In the 25 non-anaplastic bilateral WTs, differentiated cases (one epithelial, eight stromal, 33.3% abdominal stage III) were more frequent (P = 0.048) than in unilateral WTs (one stromal, abdominal stage III relapsed). In all, 52.9% of the 5-year survivors had received adriamycin (250-400 mg/m(2)), 25.7% radiation, 6.4% ifosfamide (24-30 g/m(2)) and 6.7% carboplatin plus etoposide. Abnormal parameters according to the National Cancer Institute score were seen in 18.9% during follow-up, but only 6.4% were treated for morbidity at the end of follow-up. Three WTs developed renal failure due to Drash syndrome, but none due to tumor therapy. After adriamycin 1.9% of WTs (9% of those receiving 400 mg/m(2)) required therapy for cardiac toxicity. CONCLUSIONS Initial therapy should be more individualized, taking the above risk groups (age in non-anaplastic WTs, poor response, anaplasia, etc.) into account, as morbidity even after relapse therapy with ifosfamide, carboplatin and etoposide was not high. Milder therapy in low stages of differentiated and of well responding WTs should be tested.

Abstract
PURPOSE The optimal treatment for intracranial germinomas remains controversial. We report on our 25-year experience using craniospinal irradiation (CSI) for this disease. METHODS AND MATERIALS Between September 1976 and May 2001, 39 patients with biopsy-proven intracranial germinomas seen at the Children's Hospital of Philadelphia/Hospital of the University of Pennsylvania received CSI. Thirteen of 36 patients (36%) had evidence of spinal dissemination. Median doses to the whole brain, primary site, and spine were 36 Gy (range, 18-44.2 Gy), 50.4 Gy (range, 44-55.8 Gy), and 30.6 Gy (range, 18-40 Gy), respectively. RESULTS With a median follow-up of 7.1 years (range: 1.5-20.2 years), there have been no documented relapses. This includes 5 patients without spinal dissemination who received 18-19.8 Gy to the craniospinal axis; for these patients, the median length of follow-up was 5.5 years (range, 1.3-6.8 years). One patient, who had no evidence of disease 12.9 years after CSI, died of unknown causes 4 months later. CONCLUSIONS Our treatment of intracranial germinomas with CSI has yielded outstanding results with no known relapses during a long follow-up period. These results must be considered when evaluating other approaches, such as chemotherapy only or local field irradiation.

Abstract
Over the past 3 decades, enormous advances have been made in the creation of a standardized treatment protocol for Wilms' tumor. Less morbid regimens for low-risk patients and more efficacious aggressive treatment protocols for high-risk patients have been developed, and continue to be improved with newer studies, such as the NWTS-V. An area that has posed a more challenging aspect of the disease is its relapse. Although a standard follow-up protocol has been produced by in-depth evaluation of previous works, there has been a great deal of difficulty demonstrating improved relapse-free and overall survival rates in re-treatment of children suffering from recurrent Wilms' tumor. Several factors are involved in the success of treatment of relapse, some of which include prerelapse treatment of initial disease and stage, site, and timing of recurrence. New agents and their combination with chemotherapeutics that already have established efficacy are being used for treatment of Wilms' tumor relapse, with varying success. These studies should lead the way for newer investigations in the future. Patients with anaplastic disease, rhabdoid tumors, and clear cell sarcoma are especially in need of these future investigations. Perhaps the true final frontier is establishing the likelihood of patients suffering a relapse. This topic currently is being studied in the fields of biologic markers and gene expression. This knowledge will hopefully, in turn, tailor initial treatment in a more specific manner.

Abstract
Each year advances are made in the clinical evaluation and treatment of genitourinary tumors in children. Understanding of cellular, molecular, and genetic processes in tumorigenesis is evolving rapidly. In addition, information is accumulating about the long-term outcome and complications associated with treatment modalities. This article reviews the 2001 literature on pediatric Wilms tumor, other renal tumors, rhabdomyosarcoma of the pelvis, paratesticular rhabdomyosarcoma, and testicular tumors. The emphasis in molecular biology is to identify molecular or genetic markers that predict outcome. The National Wilms' Tumor Study Group reported on the complications of surgery and the decreased complication rate when these procedures are performed by pediatric surgical specialists. Long-term complications of treatment are also discussed, including short stature and leukemia. The Intergroup Rhabdomyosarcoma Study Group reported on the results of treatment for nonmetastatic disease and the goals of the upcoming Study V, reduction of chemotherapy and radiotherapy. They also presented data from Study IV and discussed the findings on improved prognosis.
