Abstract
BACKGROUND As radiation therapy (RT) for Wilms tumor (WT) evolves with more conformal techniques, it is necessary to evaluate patterns of failure and toxicity. We sought to determine the rate of local failure (LF) after abdominal RT in WT, specifically focusing on those with contained rupture treated with whole abdominal and pelvic RT (WAPRT) vs flank RT. Secondary objectives were to determine overall survival (OS), distant failure (DF), and late toxicities. METHODS A single institution retrospective study of 54 pediatric patients with WT treated with abdominal RT between May 2000 and October 2022. LF and DF were calculated through cumulative incidence function and OS by Kaplan-Meier method. RESULTS The median age was 4.5 years and the median follow-up was 6 years. Most patients (91%) had favorable histology. Only 1 patient experienced LF, 15 months from completion of RT (cumulative incidence 2% at 5 y). All patients who received unilateral flank radiation for contained rupture/spillage (n=13) experienced long-lasting intra-abdominal tumor control. A total of 5 patients experienced a DF at a median of 7 months, all in the lung. No patient relapsed in the lungs after upfront whole lung irradiation (n=16). OS was 96% at 5 years. Among 28 patients who followed through puberty, 4 female patients with prior WAPRT experienced hormonal irregularities/infertility. CONCLUSIONS Unilateral flank radiation may be a viable alternative to WAPRT for contained rupture/spillage and should be further explored prospectively. Our results may also be utilized in the future for outcome and toxicity comparison as conformal radiation techniques evolve.

Abstract
The treatment of bilateral Wilms tumors (BWT) involves curing the cancer, preserving long-term renal function, and maintaining a good quality of life. Established methods for achieving these goals include preoperative chemotherapy and nephron-sparing surgery (NSS). This study aimed to evaluate the experience of a single institution in treating patients with BWT. We analyzed cases of BWT treated at the Pediatric Oncology Institute-GRAACC-Federal University of São Paulo over a period of 35 years. Bleeding control was performed with manual compression of the renal parenchyma. Thirty-three patients were included in the study. Thirty cases were synchronous tumors. The mean age at diagnosis was 30.4 months (±22 m) and 66.7% were girls. The median follow-up period was 83 months. Neoadjuvant chemotherapy was the primary approach in most patients (87.9%), with a simultaneous upfront surgical approach performed in 84.8%. Most patients underwent bilateral NSS (70.4%). There were no early complications in this series, but 39.4% had clinical complications. The five-year survival rate was 76%. Therefore, it is clear that the surgical approach to BWT plays a crucial role in achieving good outcomes. However, it is difficult to standardize surgical techniques and technology may have the potential to enhance safety.

Abstract
The objectives for the treatment of Wilms tumor in both the Children's Oncology Group (COG) and the International Society of Paediatric Oncology (SIOP) have focused on improving cure rates and minimizing toxicity by limiting the use of radiation and doxorubicin. Although the timing of surgery is different in COG (upfront surgery) and SIOP (upfront chemotherapy with delayed surgery), both are effective strategies and have the same survival. Fewer patients are treated with radiotherapy in the SIOP trials but with higher doses. The prognostic significance of biological markers such as 1q gain and clinical outcomes with novel radiation techniques such as intensity modulated radiation therapy will be determined in upcoming clinical trials. A closer collaboration between COG and SIOP could help promote research and improve the clinical outcomes of children with Wilms tumor.

Abstract
AIM Definitions of nephron-sparing surgery (NSS) procedures in Wilms tumor (WT) are not clear. The new UMBRELLA protocol offers a formula (NSS(X)-SRM(n)-PRM(n)-RRP(n%)) to better define the different NSS parameters. We aimed to assess the advantages and limits of this new formula. METHODS This retrospective monocentric study included patients operated by NSS for WT from 1975 to 2018. We reviewed the medical records and applied the NSS formula to all included patients. RESULTS Eighty kidneys were operated on 56 patients at a mean age of 19.2 months (4 days-7.5 years), with 49 partial nephrectomies and 31 tumorectomies. The assessment of the surgical resection margins (SRM) showed a doubt in six cases and one tumor breach. An intact pseudocapsule along the resection margin with no renal parenchyma was found in four cases at pathological resection margins (PRM) assessment, whereas a tumor breach was described in seven cases. Among the six patients with a surgical doubt, only one had a pathological stage III. There were no surgical doubts in the seven patients with tumor breach at pathology. At a mean follow-up of eight years (15 days-28.6 years), eight patients had elevated blood pressure levels. Ten had proteinuria. These two parameters were significantly increased in patients with a remaining renal parenchyma (RRP) of less than half of the initial total renal parenchyma. The serum creatinine level was normal for all except two patients. CONCLUSION The new NSS formula described all the crucial elements of NSS. RRP seemed essential for the evaluation of long-term renal function.

Abstract
PURPOSE Because of the increasing use of nephron-sparing surgery (NSS) in bilateral Wilms tumor, we sought to review the early postoperative complications associated with NSS. METHODS A retrospective review of patients who underwent NSS at our institution from 2000 to 2017 was performed. For comparison, a cohort of patients who underwent radical nephrectomy (RN) was also reviewed. Early (30-day) postoperative complications and oncologic outcomes were assessed. RESULTS Fifty-five patients underwent either bilateral (46) NSS or unilateral (9) NSS owing to prior resection or congenital solitary kidney. Fifty-four patients who underwent unilateral RN were also evaluated. Twenty NSS patients (36.4%) experienced 21 postoperative complications, including prolonged urine leak (9), infection (8), transient renal insufficiency (1), and intussusception (3). Seven RN patients (13.0%) experienced surgical complications, including infection (4) and intussusception (3). Average intraoperative blood loss was significantly greater in NSS as compared to RN (483.51 ± 337.92 mL and 278.15 mL ± 390.25, respectively, p < 0.001), as was the incidence of positive tumor resection margins (20 [36.4%] and 12 [22.2%], respectively, (p = 0.037). CONCLUSIONS In our experience, prolonged urine leak, intraoperative blood loss, and positive margins were more frequent in patients undergoing NSS as compared to RN. However, the complications were successfully managed, suggesting that an aggressive approach to NSS in patients with bilateral Wilms tumor is safe and appropriate. LEVEL OF EVIDENCE Level III TYPE OF STUDY: Treatment study.

Abstract
Context: Synchronous Bilateral Wilms tumor (sBWT). Aims: This study aimed to assess the outcome of patients with sBWT treated on SIOP protocol. Settings and Design: Retrospective and prospective randomized study. Subjects and Methods: SIOP 93-01 protocol was used to study nine patients of sBWT in a single center and followed up over a period from 2 to 5 years. Statistical Analysis Used: Unpaired t-test and Mann–Whitney U-test were used for analysis. Results: Of nine patients, six were included in the study as three patients lost to follow-up. Among the six patients, there were four girls and two boys with a median age of 2 years. Mean regression in the size of tumor was 87% in four out of six patients. Tumor with unfavorable histology showed 32% response (ratio of favorable: unfavorable histology 2:1). Event-free survival rate was 81.3% and overall survival was 90% over 2–5 years. Recurrence was seen in two patients of whom one had Denys–Drash syndrome. Mean DTPA glomerular filtration rate was 91.4/ml/min/1.73 m2 preoperatively and that of 3 months after completion of treatment was 84/ml/min/1.73 m2. Health-related quality of life (HRQOL) using Pediatric Quality of Life Inventory and Lansky Play Performance Scale revealed significant improvement results of all functioning domains such as physical, social, emotional, and school subscales with P < 0.05 and performance scale (P < 0.04). Conclusions: We suggest SIOP protocol for sBWT and bilateral nephron-sparing surgery in two stages. However, long-term follow-up is required to assess the ultimate renal function outcome. HRQOL is an essential guide in improving the conditions of pediatric cancer survivors.

Abstract
BACKGROUND Chemotherapy is used preoperatively for children with bilateral Wilms tumor (BWT) or unilateral high-risk Wilms tumor (UHRWT) to promote tumor regression to facilitate renal preservation with nephron-sparing surgery (NSS). In adults, various surgical techniques have been described to preserve renal tissue. Few studies have examined the use of surgical adjuncts in NSS in children with renal tumors. METHODS We performed a multi-institutional retrospective review of patients with BWT or UHRWT. Patient demographics, tumor size at diagnosis, following neoadjuvant chemotherapy, utilization of surgical adjuncts including intraoperative ultrasound (IOUS), margin status, complications, renal function, and follow-up were recorded. RESULTS The cohort comprised 23 patients: 18 BWT, 3 UHRWT, and 2 patients with solitary kidney. Twenty-two of the 23 patients had successful NSS. IOUS was used 19 times, and seven had positive margins after surgery. Cooling/vascular isolation was used six times. At a median follow-up of 18 mo, median estimated glomerular filtration rate Schwartz was 126 mL/min/1.73 m2 and median serum creatinine 0.39 mg/dL in the 22 patients who had successful NSS. There have been no tumor recurrences. CONCLUSIONS In patients with BWT and UHRWT, surgical adjuncts such as cooling/vascular isolation are uncommonly performed. IOUS may be helpful but does not guarantee negative microscopic margins. LEVEL OF EVIDENCE Level 4, Case series with no comparison group.

Abstract
OBJECTIVES Wilms tumor is the most common renal cancer in children. Approximately 5% of children with Wilms tumor present with disease in both kidneys. The treatment challenge is to achieve a high cure rate while maintaining long-term renal function. We retrospectively reviewed our institutional experience with nephron sparing surgery (NSS) in patients with synchronous bilateral Wilms tumor (BWT) operated on between 2001 and 2014. METHODS Imaging studies, surgical approach, adjuvant therapy, and pathology reports were reviewed. Outcomes evaluated included surgical complications, tumor recurrence, patient survival, and renal function, as assessed by estimated glomerular filtration rate. RESULTS A total of 42 patients with BWT were identified: 39 (92.9%) patients underwent bilateral NSS; only 3 patients (7.1%) underwent unilateral nephrectomy with contralateral NSS. Postoperative complications included prolonged urine leak (10), infection (6), intussusception (2), and transient renal insufficiency (1). Three patients required early (within 4 months) repeat of NSS for residual tumor. In the long-term, 7 (16.7%) patients had local tumor recurrence (managed with repeat NSS in 6 and completion nephrectomy in 1) and 3 had an episode of intestinal obstruction requiring surgical intervention. Overall survival was 85.7% (mean follow-up, 4.1 years). Of the 6 patients who died, 5 had diffuse anaplastic histology. All of the patients had an estimated glomerular filtration rate more than 60 mL/min/1.73 m at the last follow-up; no patient developed end-stage renal disease. CONCLUSIONS In patients with synchronous, BWT, bilateral NSS is safe and almost always feasible, thereby preserving maximal renal parenchyma. With this approach, survival was excellent, as was maintenance of the renal function.

Abstract
BACKGROUND Renal insufficiency is a significant complication of Wilms tumor treatment in the 5% with bilateral disease. Nephron-sparing surgery (NSS) is recommended after neoadjuvant chemotherapy initially. However, the role of NSS in recurrent disease is unknown. We reviewed our experience to assess the feasibility and oncologic and functional outcomes of repeat NSS for children with recurrent disease. METHODS A retrospective review was performed of all children treated at our institution for bilateral, favorable histology (FH) Wilms tumor. Patients undergoing repeat NSS for locally recurrent disease were identified. The outcomes evaluated included tumor recurrence, renal function, and patient survival. RESULTS Since 2001, 36 children with bilateral FH Wilms tumor have been treated at our institution. Eight patients (22%) underwent repeat NSS for locally recurrent disease. Two patients had a second local recurrence and underwent a third NSS. Six patients are alive without disease (75%) with an average follow-up of 4.5years. Two patients have died, each with blastemal-predominant histology at repeat NSS. The surviving patients have normal renal function, although two patients require medical management of hypertension. CONCLUSIONS Our experience suggests that repeat NSS for local recurrence of FH bilateral Wilms tumor is feasible and affords acceptable oncologic outcome with preservation of renal function. However, more aggressive therapy may be required for patients whose recurrence has blastemal-predominant histology, given the poor outcome for these patients in our series.

Abstract
OBJECTIVE To provide guidelines for future trials, we reviewed the outcomes of children with synchronous bilateral Wilms tumors (BWT) treated on National Wilms Tumor Study-4 (NWTS-4). METHODS NWTS-4 enrolled 3335 patients including 188 patients with BWT (5.6%). Treatment and outcome data were collected. RESULTS Among 188 BWT patients registered with NWTS-4, 195 kidneys in 123 patients had initial open biopsy, 44 kidneys in 31 patients had needle biopsies. Although pre-resection chemotherapy was recommended, 87 kidneys in 83 patients were managed with primary resection: Complete nephrectomy 48 in 48 patients, 31 partial/wedge nephrectomies in 27 patients, enucleations 8 in 8 patients. No initial surgery was performed in 45 kidneys in 43 patients, 5 kidneys in 3 patients not coded. Anaplasia was diagnosed after completion of the initial course of chemotherapy in 14 patients (initial surgical procedure: 9 open biopsies, 4 needle biopsies, 1 partial nephrectomy). The average number of days from the start of chemotherapy to diagnosis of anaplasia was 390 (range 44-1925 days). Relapse or progression of disease occurred in 54 children. End stage renal failure occurred in 23 children, 6 of whom had bilateral nephrectomies. The 8 year event free survival for BWT with favorable histology was 74%, and overall survival was 89%; whereas the event free survival for BWT with unfavorable histology was 40%, overall survival was 45%. CONCLUSION The current analysis of patients with BWT treated on NWTS-4 shows that preservation of renal parenchyma is possible in many patients after initial preoperative chemotherapy. The incidence of end-stage renal disease remains significantly higher in children with BWT. Future studies are warranted to address the need for earlier biopsy in nonresponsive tumors and earlier definitive surgery to recognize unfavorable histology in these high-risk patients.

Abstract
OBJECTIVES Bilateral Wilms' tumors represent a therapeutic challenge. The primary aim of management is eradication of the neoplasm and preservation of renal function. We present our experience in the management of such cases in a single-center experience. METHODS This was a retrospective study of 22 patients with histologically proven bilateral nephroblastoma who were treated from 1993 to 2008 at our center. Of the 22 patients, 12 were girls and 10 were boys, with a median age of 3 years (range 1-9); 19 had a synchronous presentation and 3 a metachronous presentation. Of the 22 patients, 6 underwent initial surgical resection followed by chemotherapy and 16 underwent initial biopsy and preoperative chemotherapy. The final oncologic and renal outcomes were assessed. RESULTS The median follow-up period was 3 years (range 1-11). Of the 22 patients, 8 died, for an overall survival rate of 63.5%. The survival for the initial chemotherapy and initial surgery groups was essentially similar. Of all the variables studied, unfavorable histologic findings had a significant negative effect on survival. Of the 5 patients with unfavorable histologic findings, 4 died during the follow-up period. The median volume of preserved renal parenchyma was 40%. All patients had good renal function during follow-up, except for 1 patient who had undergone bilateral nephrectomy. CONCLUSIONS Bilateral Wilms' tumors impose 2 conflicting issues: elimination of the pathology and preservation of the renal function. Currently, treatment regimens involving initial chemotherapy followed by conservative surgery can achieve these goals in an important proportion of patients.

Abstract
PURPOSE In 1996, the Japan Wilms Tumor Study (JWiTS) group was founded to elucidate the efficacy and safety of the regimen established by the National Wilms Tumor Study (NWTS) group in the USA, and a multicenter cooperative study (JWiTS-1) was started in Japan. This report reviews the results of JWiTS-1. METHODS A total of 307 patients with malignant renal tumor were enrolled in the JWiTS-1 study between 1996 and 2005. Central pathological diagnosis and follow-up data were available in 210 cases. The protocol regimens were similar to the NWTS-5 regimens. Clinical stage was classified according to the Japanese Staging System. RESULTS Five-year overall survival (OS) rate was 91.1% for nephroblastoma, 72.9% for clear cell sarcoma of the kidney (CCSK), and 22.2% for rhabdoid tumor of the kidney (RTK). In the nephroblastoma patients, 5-year OS was 90.5% for stage I disease, 92.2% for stage II, 90.9% for stage III, 86.7% for stage IV, and 78.7% for stage V. CONCLUSIONS The OS of patients in the JWiTS-1 study were comparable with the results of other multicenter studies in the USA and Europe. The outcome for patients with nephroblastoma and CCSK was fair. In contrast, the cure rate for those with RTK was not satisfactory. New treatment strategies are needed for patients with RTK.

Abstract
PURPOSE We reviewed the long-term local tumor control in patients with bilateral Wilm's tumor (BWT) who received no definitive surgical therapy to one kidney after complete radiographic resolution after initial chemotherapy. METHODS National Wilm's Tumor Study 4 (NWTS-4) enrolled 3335 patients (pts) during the period August 1986 to August 1994. There were 188 pts with BWT or 5.6% of the total enrolled. The treatment records and imaging reports were reviewed to ascertain those children who had documented tumors without definitive surgical therapy after initial treatment. Patients who did not have renal surgery because of progression of tumor were excluded from this study. RESULTS Eleven children had no definitive surgical treatment of renal lesions in one kidney (right, 6; left, 5) after initial treatment with chemotherapy and/or radiation therapy. The pretreatment size of the lesions were less than 3 cm (4 pts), 3 to 6 cm (5 pts), more than 6 cm (1 pt), and unknown (1 pt). Prechemotherapy biopsy was performed in 6 of 11 patients. Lesions were less than 3 cm (1 pt), 3 to 6 cm (3 pts), more than 6 cm (1 pt), and unknown (1 pt). Four biopsy specimens showed favorable Wilm's histologic findings. One lesion (4 cm) showed an intralobar nephrogenic rest, another lesion of unknown size was read as favorable histologic findings vs perilobar nephrogenic rest. Biopsy was not performed on 5 lesions (4 pts, <1 cm; 1 pt, 3cm). Only 2 children in this study received radiation treatment. One child received 1050 cGy whole abdominal radiation, and 1 child received 1060 cGy to the left flank postnephrectomy. Radiation therapy was not given to any patient because of failure of the tumor to respond to chemotherapy. Five patients received treatment regimen EE-4A, dactinomycin, and vincristine. The duration of therapy ranged from 24 to 102 weeks for an average of 55.6 weeks. Three patients received treatment regimen DD-4A, dactinomycin, vincristine, and doxorubicin for 28, 52, and 52 weeks, respectively. Three patients received 2 separate regimens of chemotherapy. One child was treated with dactinomycin, vincristine, and cyclophosphamide for 60 weeks and then received regimen EE-4A for 24 weeks. Another patient received regimen EE-4A for 16 weeks and then regimen DD4-A for 36 weeks. One child received regimen EE-4-A for 12 weeks and then regimen DD4A for 40 weeks. Management of the contralateral kidney was complete nephrectomy in all 11 patients. There were no local relapses in the renal tumor bed. All patients were alive at a median follow-up of 9 years (range, 9 months to 15 years). CONCLUSION Children with synchronous BWT or Wilm's tumor and contralateral nephrogenic rests that have radiographic resolution, after initial treatment, have a low risk for local relapse. These children should be followed by serial imaging.

Abstract
AIMS To review the management of Wilms' tumour. METHODS A search of the literature was performed using the PubMed database (1966 to May 2006) with the search terms 'Wilms' and either 'tumour/tumor' or 'cancer' or 'carcinoma'. This was augmented by manual searches of publications. FINDINGS The success of clinical trials in Wilms' tumour patients over the past 30 years has led to an overall survival of 85% and the introduction of less aggressive chemotherapeutic regimes for patients. Large randomised controlled trials have been published on the management of Wilms' tumour by various collaborative groups, including the National Wilms' Tumour Study Group (NWTSG) in North America and the Société Internationale d'Oncologie Pédiatrique (SIOP) plus the United Kingdom Children's Cancer Study Group (UKCCSG) in Europe. CONCLUSIONS Controversy exists as to the best approach to the management of these children with regard to neoadjuvant chemotherapy. Challenges remain in the identification of histological and molecular risk factors for the stratification of treatment intensity.

Abstract
Nephron-sparing surgery (NSS) is the treatment of choice for children with bilateral Wilms' tumor (WT), or with WT on a single kidney, or with WT and a disease of the contralateral kidney, or with benign kidney tumor. NSS is a reasonable alternative to nephrectomy in children at risk of metachronous WT, including children with genetic syndromes, children younger than 1 year of age, and children with hyperplastic nephroblastomatosis. The use of NSS in selected children with "low-risk" or stage I "intermediate-risk" WT and a normal contralateral kidney is still controversial. Available data suggest that, in children with WT, NSS does not impair the outcome and has a renal function advantage over nephrectomy.

Abstract
Wilms' tumor was the first solid malignancy in which the value of adjuvant chemotherapy was established. Multimodality treatment has resulted in a significant improvement in outcome from approximately 30% in the 1930s to more than 85% in the modern era. Although the National Wilms' Tumor Study Group and the International Society of Pediatric Oncology differ philosophically regarding the merits of preoperative chemotherapy, outcomes of patients treated with either up-front nephrectomy or preoperative chemotherapy have been excellent. The goal of current clinical trials is to reduce therapy for children with low-risk tumors, thereby avoiding acute and long-term toxicities. At the same time, current clinical trials seek to augment therapy for patients with high-risk Wilms' tumor, including those with bilateral, anaplastic, and recurrent favorable histology tumors.

Abstract
Pediatric renal tumors were targeted by the National Wilms Tumor Study Group for 4 decades with extraordinary success. Within this historic context, this review provides a summary of the new Children's Oncology Group renal tumor protocols that will be opening in the very near future, focusing on their pathologic requirements. All renal tumors must first be registered on the Renal Tumor Classification and Banking Protocol, followed by registration on 1 of 4 primary therapeutic protocols based on histology, stage, and molecular analysis. This requires prompt submission of samples for molecular analysis and central pathologic review. Changes in staging criteria include classification of all tumor spillage as stage III, and requirement of regional lymph node evaluation for eligibility for stage I Wilms tumors (WTs) weighing less than 550 g in infants younger than 24 months and for stage I clear cell sarcoma. Patients with unilateral favorable histology WT with loss of heterozygosity for chromosomes 1p and 16q will receive more aggressive chemotherapy at each stage. Patients with bilateral WT and patients with diffuse hyperplastic perilobar nephroblastomatosis will be eligible for a novel therapeutic protocol requiring pathologic classification based on response of tumor to previous therapy. Stage I anaplastic WT will be targeted with more aggressive chemotherapy than in the past. For the first time, pediatric renal cell carcinoma will be eligible for a cooperative group protocol. All rhabdoid tumors outside the central nervous system will be eligible for a single protocol. In conclusion, these new protocols bring considerable change in their overall organization, in eligibility, and in therapy.

Abstract
PURPOSE Maintaining adequate renal function without compromising cure in children with bilateral Wilms' tumor is surgically demanding and challenging. The aim of this study was to assess renal function and outcome in children treated in one institution for bilateral Wilms' disease by renal salvage procedures. METHODS This study is a retrospective review of all patients with histologically proven bilateral nephroblastoma who underwent a renal salvage procedure between November 1973 and June 2002. The median follow-up time was 52 months (range, 8 to 326 months). RESULTS Twenty-three patients were included in the study. The median age at diagnosis was 19 months (range, 5 to 65 months). Patients who presented before 1982 (n = 5) were treated surgically first followed by chemotherapy. The remainder (n = 18) received initial chemotherapy before the operation. Of the 46 kidneys, 18 had a nephrectomy. The remaining 28 underwent a renal salvage procedure. At follow-up, 19 patients had good renal function, 2 had satisfactory function, and 2 had renal failure. Seventeen of the 23 children are alive and tumor free at follow-up (74%). Four children died of distant metastases and 2 of renal failure. Local recurrence in the salvaged kidney was detected in 1 patient 12 years after surgery after the commencement of immunosuppression for renal transplantation. CONCLUSIONS These results confirm that renal salvage procedures, in combination with chemotherapy, are a safe and effective way of treating children with bilateral Wilms' disease. In addition, renal salvage surgery can maintain satisfactory renal function in the majority of these patients without an increased risk of local recurrence. When transplantation is required, the remaining native kidney should be removed to prevent tumor recurrence.

Abstract
BACKGROUND Synchronous bilateral Wilms' tumor is rare and experience with renal salvage procedures and their limitations accumulates slowly at single institutions. The authors analyzed whether their growing experience with atypical renal resections and awareness of nephroblastomatosis had influenced the outcome of surgical procedures. METHODS Retrospective analysis of patients treated from 1977 to 1995 was performed. Surgical reports, clinical sheets, and follow-up data were evaluated. All pathology slides were reviewed for histological classification and presence of nephroblastomatosis. Renal function was evaluated pre- and postoperatively and at final follow-up. RESULTS Fourteen patients were treated. Two to 20 years after surgery, 13 patients are alive, and none has had renal failure. Five patients had unilateral nephrectomies, and a renal salvage procedure was performed on 22 kidneys. One patient with an anaplastic bilateral Wilms' tumor died of tumor progress 1 year after surgery. Several kidneys, which would have been sacrificed by application of traditional criteria, could be salvaged by atypical and unconventional tumor resections and by superficial dissection and enucleation of supposed nephroblastomatosis. Nephrectomy appeared unavoidable with hilar invasion by tumor. CONCLUSION Atypical resections of localized lesions and superficial dissections of suspected nephroblastomatosis appeared as valid surgical treatment options for patients who would otherwise have been candidates for nephrectomy. In the case of hilar tumor invasion, however, nephrectomy seems unavoidable.

Abstract
Bilateral Wilms' tumor occurs at a younger age than unilateral disease. While it generally has a good prognosis, it presents a therapeutic dilemma to balance curative surgical resection with preservation of renal tissue. A 15 year review of bilateral Wilms' tumors diagnosed at Princess Margaret Hospital was undertaken. Of 46 Wilms' tumor cases, eight were designated bilateral by diagnostic imaging (median age 1.1 years compared with 3.5 years for unilateral tumors). The surgical management entailed primary nephrectomy with contralateral biopsy in two patients, and bilateral biopsy and delayed resection in all remaining surviving patients (one patient died of perioperative complications). Seven patients had localized disease (stage I/II) and the six surviving patients received chemotherapy with vincristine and actinomycin; no patient received radiotherapy. All are alive and well (median follow-up 5.1 years). The remaining patient presented with pulmonary metastases and died of disease progression. Pathologic review revealed that four patients had truly bilateral disease demonstrable by histology, three had unilateral Wilms' tumor with contralateral nephrogenic rests, and in one patient the biopsies of the contralateral kidney showed neither tumor nor nephrogenic rests. In most cases pathological material was subject to external review. Follow-up demonstrates excellent renal function with compensatory hypertrophy in the remaining renal tissue. Conservative surgery and simple out-patient based, low toxicity chemotherapy is curative in most patients.

Abstract
PURPOSE Bilateral Wilms tumor presents the clinician with a treatment dilemma. Since 1980 most centers of the United Kingdom Children's Cancer Study Group have used a conservative surgical approach with initial biopsy followed by chemotherapy and delayed surgical resection. We assess the outcome of this treatment approach in terms of survival, and preservation of renal mass and function. MATERIALS AND METHODS We retrospectively analyzed the records of 71 children with bilateral Wilms tumor diagnosed between 1980 to 1995 at 17 United Kingdom Children's Cancer Study Group centers. In 57 patients conservative surgical treatment with initial biopsy was followed by chemotherapy and delayed tumor resection, while 13 underwent initial surgical resection followed by chemotherapy. One patient was excluded from study because the lesion in 1 kidney proved to be a benign cyst. Mean followup was 6 years (range 1 to 15). The percentage of renal tissue involved with tumor and preserved was estimated, and renal function at the last followup was recorded. RESULTS Overall survival was 69% with similar survival in the conservatively treated and initial surgical resection groups. At the last followup renal function was normal in 80% of the patients in each group. Mean preserved renal mass was 45 and 35% in the conservatively treated and initial resection groups, respectively, with a trend toward better preservation in those treated conservatively. Bilateral Wilms tumor with an unfavorable histology was associated with a poor prognosis. CONCLUSIONS Conservative surgical treatment of favorable histology bilateral Wilms tumor may improve the preservation of renal mass and function without impairing patient survival.

Abstract
The treatment of bilateral Wilms tumor (BWT) involves a multidisciplinary approach including surgery, chemotherapy, and radiation therapy. The long-term renal function in patients receiving all three treatment modalities has not been evaluated. Long-term renal function was evaluated in 81 children with synchronous BWT who received radiation therapy as part of their treatment. Renal function was assessed by measuring blood urea nitrogen (BUN) and serum creatinine (Cr). The normal range for the BUN was defined as 10-24 mg/dl, and the Cr was considered normal at levels of <1.5 mg/dl. Moderate elevations were defined as a BUN of 25-50 mg/dl and/or a Cr of 1.6-2.5 mg/dl and marked elevations as a BUN of >50 mg/dl and/or a Cr of >2.5 mg/dl. BUN and Cr levels were measured prior to treatment and at the following intervals: 6 months after treatment, 1 year after treatment, 2 years after treatment, and at last follow-up. Any elevation during the posttreatment follow-up period was considered abnormal. A total of 28 children (34.6%) had elevated BUN and/or Cr levels, and 18 had moderate and 10 had marked renal insufficiency. No dose-response relationship was established when comparing the radiation doses of those with elevated values to those with normal values. The renal complication rate was moderate, and other factors including surgery, extent and nature of chemotherapy, and recurrent tumor must also be taken into account. The elevations present in several children could be attributed to tumor recurrence and in one case to gentamicin toxicity. The management of children with BWT should consider all of these risks, and attempts to preserve renal parenchyma are warranted.

Abstract
PURPOSE To evaluate the role of radiation therapy (RT), chemotherapy (CT), and surgery in the local control of synchronous bilateral Wilms Tumor (WT). METHODS AND MATERIALS Between 1962 to 1993, 45 children were treated for bilateral WT; 38 patients with synchronous tumors were reviewed. Initial surgery depended on the era of treatment and included unilateral nephrectomy (N)/partial nephrectomy (PN) and contralateral PN in 6, unilateral N/PN alone in 7, and biopsy only in 25. Chemotherapy (CT) consisted of vincristine, actinomycin-D, and adriamycin in 32 and vincristine/ actinomycin-D in 6. Radiation therapy (RT) was given to 32 patients. Treatment included both kidneys in 20, unilateral kidney plus contralateral renal bed in 9, unilateral kidney in 2, and unilateral renal bed in 1. Follow-up was 16 months to 25 years (median: 6.3 years). RESULTS Local control (LC) has been maintained in 66 out of 76 sites (87%). For Stage I-II disease with initial N/PN, LC was 10 out of 12 with RT and 11 out of 11 without RT; for Stage III with initial N/PN, LC was 8 out of 9 with RT and 1 out of 1 without RT. Initial CT and RT was followed by delayed N/PN for 20 sites; LC was 15 out of 17 in post induction Stage I-II and 1 out of 3 in postinduction Stage III. In 23 sites undergoing biopsy and chemotherapy, LC was 19 out of 20 with RT and 1 out of 3 without RT. Seven of 23 sites had a complete response (CR) after induction CT, and LC was maintained in four out of four with RT and one out of three without RT. Univariate Cox Regression analysis demonstrated that sites receiving two drugs had a statistically significant increase in loco-regional relapse when compared to sites receiving three drugs (p = 0.004). Major morbidities related to multimodality therapy have included renal failure in one patient and small bowel obstruction requiring lysis of adhesions in two patients. CONCLUSIONS Local control does not seem to be compromised by renal conservation therapy. Local control is excellent in sites treated with radiation therapy in combination with three drug chemotherapy.

Abstract
PURPOSE Surgical exploration of the contralateral kidney in patients with Wilms tumor is standard practice. The introduction of modern imaging techniques (ultrasound, computerized tomography and magnetic resonance imaging) in place of excretory urography has led to a more accurate definition of intrarenal pathology. Is contralateral kidney exploration still necessary in patients with Wilms tumor? MATERIALS AND METHODS We reviewed the records of 75 patients from 3 medical centers who were evaluated and treated for Wilms tumor in the last 14 years. All children underwent preoperative excretory urography, computerized tomography, ultrasound and/or magnetic resonance imaging. RESULTS Seven bilateral Wilms tumors were diagnosed preoperatively and confirmed surgically, whereas extensive operative exploration of the contralateral kidney in the other 69 patients revealed no additional pathological condition. This concurred with preoperative radiological findings with 100% sensitivity and specificity. Furthermore, 1 month to 12 years of followup (mean 4.3 years) revealed no tumor in the contralateral kidney. The major postoperative complication was small bowel obstruction in 5 patients 15 to 180 days (mean 77.2) after explorative laparotomy. CONCLUSIONS In all patients preoperative radiological investigation was accurate in excluding bilaterality. With modern imaging techniques and effective chemotherapy extensive contralateral renal exploration may no longer be mandatory for managing Wilms tumor.

Abstract
Synchronous bilateral Wilms' tumor accounts for 4% to 6% of all Wilms' tumors. Renal salvage procedures (partial nephrectomy and enucleation) have been recommended to conserve renal parenchyma. The objective of this study was to review the results of renal salvage operations performed in children who had bilateral neoplasms. The authors reviewed the records of 98 children enrolled in the Fourth National Wilms' Tumor Study who had synchronous bilateral tumors and underwent renal salvage procedures. One hundred thirty-four kidneys were managed with renal salvage procedures. Complete excision of gross disease was accomplished in 118 (88%) of the 134 kidneys. Local tumor recurrence in the remnant kidney or tumor bed occurred in 11 cases (8.2%). Overall, 72% of the kidneys were preserved, and the 4-year survival rate was 81.7%. The surgical morbidity after a salvage procedure was comparable to that of a complete nephrectomy in patients with unilateral Wilms' tumor. Although the incidence of positive surgical margins is worrisome, it did not invariably lead to local recurrence in the remnant kidney or the tumor bed.

Abstract
This report defines the incidence and determines the etiology of renal failure (RF) in patients undergoing treatment for Wilms' tumor (WT). The database of the National Wilms' Tumor Study (NWTS) was searched to identify all children reported to have developed chronic renal failure. There were 55 patients found to have RF. Of these, 39 patients had bilateral tumors, 15 with unilateral disease and one with a WT in a solitary kidney. The median interval from diagnosis to the onset of renal failure was 21 months. The incidence of RF in bilateral WT was 16.4% for NWTS-1 & -2, 9.9% for NWTS-3, and 3.8% for NWTS-4. The incidence of RF in unilateral WT remained stable. The most common etiologies of RF were: bilateral nephrectomy for persistent or recurrent tumor (24 pts), Drash syndrome (12 pts), progressive tumor in the remaining kidney (5 pts), radiation nephritis (6 pts), and other causes (5 pts). The etiology of renal failure was not reported in three children. Children with unilateral WT and a normal contralateral kidney have a very low incidence of RF, and this review does not support a recommendation for parenchymal sparing procedures in these patients. Children with bilateral WT are at risk for the development of RF, and parenchymal sparing procedures are warranted.

Abstract
BACKGROUND Five percent of patients with Wilms' tumor will present with bilateral disease. Recent reports suggest that preoperative imaging studies can exclude contralateral disease reliably, obviating the need for formal surgical exploration of the contralateral kidney. This study was undertaken to determine the accuracy of preoperative imaging in diagnosing bilateral Wilms' tumor. METHODS The charts of 122 patients with synchronous bilateral Wilms' tumor enrolled in National Wilms Tumor Study-4 were reviewed. With the exception of one child, all had an abdominal computed tomography (CT), ultrasound, or magnetic resonance imaging performed. RESULTS There were nine patients (7%) in whom the diagnosis of bilaterality was missed by the preoperative imaging studies. All but one of the missed lesions were small, five less than 1 cm and three 1-3 cm. The accuracy of each imaging modality was correlated with tumor size. Computed tomography was more sensitive in detecting bilaterality than ultrasound. However, there was not a single study that was able to detect more than 50% of lesions less than 1 cm in greatest dimension. CONCLUSIONS This review indicates that even with current advances in imaging technology, synchronous bilateral Wilms' tumor will go unrecognized in 7% of patients if formal exploration of the contralateral kidney is omitted. Although this represents a small percentage of all patients presenting with Wilms' tumor, preoperative diagnosis of bilaterality is essential if parenchymal-sparing procedures are to be performed. Until a more reliable indicator of bilateral disease is found, exploration of the contralateral kidney continues to be recommended.

Abstract
The Brazilian Wilms Tumor Study Group has registered 16 cases of synchronous bilateral Wilms tumor since 1986, of which 14 were available for analysis. Most patients were treated according to a prospective trial in which bilateral renal preservation was emphasized. Overall survival was 79% (11 of 14 cases), and both kidneys were preserved in 57% (8 of 14) of the patients with synchronous disease. Of the 14 patients 5 had undergone at least 3 surgical procedures. In 10 cases in which pathological reports were available for review residual disease was documented in 5 but none had relapse.

Abstract
The National Wilms' Tumor Study 3 (NWTS-3) recommended treatment of bilateral Wilms' tumor with initial biopsy followed by chemotherapy with subsequent operation to resect the remaining tumor. This study was performed to determine if this approach preserves renal mass and function when compared with initial surgical resection followed by chemotherapy. Over a 20-year period (1970 to 1990), 15 patients with synchronous bilateral Wilms' tumor were treated at the Childrens Hospital of Los Angeles. Eight patients in the surgical group underwent initial unilateral nephrectomy with contralateral biopsy, wedge resection, or partial nephrectomy and subsequent chemotherapy. The seven patients in the chemotherapy group underwent bilateral tumor biopsy, followed by chemotherapy and subsequent tumor resection. Patients were assigned to each group in a nonrandomized manner according to the preference of the attending oncologist and surgeon. Comparison of the two groups showed no significant differences in sex distribution, initial renal function, tumor histology, dose and field of radiotherapy, presence or absence of positive surgical margins, and local recurrence rates. Patients in the surgery group were slightly older than those in the chemotherapy group: 3.6 +/- 2.2 versus 2.3 +/- 2.2 years. The percent of renal mass involved by tumor for the surgery group was 52 +/- 12 versus 73 +/- 16 for the chemotherapy group (P = .03). The percent of renal mass preserved following all operations, local recurrence rates, incidence of metastases, and survival was nearly identical between the two groups. There were three cases of renal failure in the surgery group and one case of renal failure in the chemotherapy group.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Despite an improving overall survival rate for children with Wilms' tumour, four out of seven patients with bilateral tumours died in the period from 1952 to 1960 and five out of eight died in the period from 1971 to 1989, at St Bartholomew's Hospital and the Hospital for Sick Children. More aggressive chemotherapy with both adriamycin and actinomycin D and concern over young age being predisposed to late radiation morbidity prompted us to keep radiotherapy dose prescriptions to the surviving kidney below the quoted renal radiation tolerance dose equivalent. In three long-term survivors treated with daily fractions up to 167 cGy and total doses of 1000-1200 cGy, we have found renal function and growth to be within the "normal" range at follow-up and the patients to be normotensive 6-8 years later. As four of the eight patients reported here died from local disease progression within the kidney (albeit despite slightly larger dose prescriptions), we discuss the potential for larger total doses to be delivered in this situation.

Abstract
During the last 6 years a treatment protocol of radiographic staging along with percutaneous biopsy to establish a histological diagnosis has been used in 37 patients with Wilms tumor. Combination chemotherapy was given for 4 to 6 weeks before definitive surgical resection. In 9 patients tumor shrinkage was sufficient to permit preservation of a portion of the affected kidney(s). In stage V disease partial nephrectomy was accomplished in 5 patients. In 4 additional patients with unilateral disease downstaging also allowed partial nephrectomy. The radiological and histological changes that allowed this limited surgery are analyzed and compared.

Abstract
The long-term survival of patients with synchronous bilateral Wilms tumor is not well defined. Retrospective review of 185 patients registered with the National Wilms Tumor Study from January 1974 to July 1986 with stage V tumors suggests that the long-term outcome remains good. Over-all survival is 83%, 73% and 70% at 2, 5 and 10 years, respectively. Unfavorable histology, age at diagnosis and the most advanced stage of the individual tumors remain the most important prognostic variables. No significant difference in survival was noted between patients undergoing initial surgical resection of the tumor and those managed with initial tumor biopsy followed by chemotherapy with or without radiotherapy and subsequent surgical resection. Survival does not appear to be compromised by attempting to conserve native renal function with renal-sparing operations.

Abstract
A 15-year-old boy had lymphoblastic lymphoma of the left tonsil after being treated for bilateral Wilms' tumor (BWT) at 7 months of age. In addition, a fully differentiated Wilms' tumor was diagnosed in the remaining, partially nephrectomized left kidney. Development of second malignancies in patients with a history of BWT, as compared with those with unilateral Wilms' tumor, is discussed. A possible explanation for the concurrently diagnosed, fully differentiated Wilms' tumor in the remaining left kidney is suggested.
