Importance of Adequate Surgical Local Control in Fusion-Negative Para-Testicular Rhabdomyosarcoma: Data From the Cooperative Weichteilsarkom Studiengruppe Trials (CWS-96 and CWS-2002P) and the European Soft Tissue Sarcoma Registry (SoTiSaR). Ann Surg Oncol 2024; 31:6209-6219. [PMID: 38879672 PMCID: PMC11300477 DOI: 10.1245/s10434-024-15568-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2024] [Accepted: 05/22/2024] [Indexed: 08/09/2024]
Abstract
BACKGROUND This study aimed to assess the impact that the quality of primary and subsequent surgeries has on the survival of patients with para-testicular rhabdomyosarcoma (PTRMS). METHODS Patients with localized (IRS I-III) and metastatic (IRS IV) PTRMS were enrolled in the two Cooperative Weichteilsarkom Studiengruppe (CWS) trials (CWS-96, CWS-2002P) and the Soft Tissue Sarcoma Registry (SoTiSaR). RESULTS Among 196 patients (median age, 8.4 years), 106 (54.1%) had primary complete resection. Image-defined lymph node (LN) disease was detected in 21 (11.5%) patients in the localized cohort and 12 (92.3%) patients in the metastatic cohort. The 5-year event-free survival (EFS) and overall survival (OS) were respectively 87.3% and 94.0% for the patients with localized PTRMS and 46.2% and 42.2% for the patients with metastatic PTRMS. Protocol violations during the primary surgery (PV-PS) were observed in 70 (42%) of the IRS I-III patients. This resulted in higher rates of R1/R2 resections (n = 53 [76%] vs n = 20 [21%]; p < 0.001) with a need for pretreatment re-excision (PRE) (n = 50 [83%] vs n = 10 [17%]; p < 0.001) compared with the patients undergoing correct primary surgery. Protocol violations during PRE occurred for 13 (20%) patients. Although PV-PS did not influence the 5-year EFS or OS in the localized PTRMS cohort, the unadjusted log-rank test showed that R status after PRE is a prognostic factor for 5-year OS (R1 vs R0 [81.8% vs 97.6%]; p = 0.02). CONCLUSIONS The quality of surgical local control in PTRMS is unsatisfactory. Emphasis should be placed on evaluating the resection status after PRE in further clinical trials.

Documentation of critical intraoperative oncologic findings: Synoptic versus narrative operative reports for childhood cancer surgery. Pediatr Blood Cancer 2024:e31269.

Abstract
BACKGROUND Documentation of intraoperative oncologic findings varies greatly across narrative operative reports (NRs). An international panel of childhood cancer experts recently developed a synoptic operative report (SR) for childhood cancer surgeries. The aim of this study was to compare the documentation of critical intraoperative findings in NRs versus SRs. METHODS A single-center retrospective review of all surgical resections of primary solid tumors at our pediatric oncology center was conducted from June 2023 to March 2024, after an institutional SR was piloted from October 2023 onwards. Data collected included the presence or absence of six components included in standard pediatric oncology NRs. Inclusion rates were calculated as percentages for each component. Due to the small sample, the Fisher's exact test was used for all hypothesis testing. RESULTS Seventy primary tumor resections were performed during the study period, as documented by 38 NRs and 32 SRs. All operative reports after October 2023 were SRs. Completeness of tumor resection and specimen naming were consistently documented in NRs (86% and 100%, respectively) and SRs (100% and 100%, respectively). The presence/absence of three components-intraoperative tumor spillage (31%), vascular involvement (31%), and lymph node sampling (26%)-were documented in fewer than a third of the NRs. Documentation of the presence/absence of locoregional spread, intraoperative tumor spillage, vascular involvement, and lymph node sampling was significantly better in SRs than in NRs. CONCLUSION Adoption of SRs significantly improved the documentation of critical intraoperative findings. Thus, we recommend using SRs in pediatric solid tumor surgery.

Abstract
INTRODUCTION Precision in surgical documentation is essential to avoid miscommunication and errors in patient care. Synoptic operative reports are more precise than narrative operative reports, however they have not been widely implemented in pediatric surgical oncology. To assess the need for implementation of synoptic operative reports in pediatric surgical oncology, we examined the completeness of narrative operative reports in patients undergoing resection of Wilms tumor. METHODS We conducted a retrospective review of narrative operative reports for resection of Wilms tumor at a single pediatric oncology center from January 2022 through July 2023. Primary outcomes were the presence or absence of 11 key operative report components. Inclusion rates were calculated as simple percentages. Unilateral and bilateral operations were considered. RESULTS Thirty-five narrative reports for Wilms tumor resection were included. The most consistently documented operative report components were estimated blood loss, indication for surgery, intraoperative complications, and specimen naming (100% documentation rates). Documentation of lymph node sampling was present in 94.3% of reports. The least consistently documented components were assessment of intraoperative tumor spillage, completeness of resection, metastatic disease, and assessment of vascular involvement (each ≤40% documentation rate). All 11 key components were documented in three reports. CONCLUSIONS Even at a large tertiary pediatric oncology referral center, narrative operative reports for pediatric Wilms tumor resection were found to be frequently missing important components of surgical documentation. Often, these were omissions of negative findings. Utilization of synoptic operative reports may be able to reduce these gaps.

Abstract
Pediatric renal tumors are among the most common pediatric solid malignancies. Surgical resection is a key component in the multidisciplinary therapy for children with kidney tumors. Therefore, it is imperative that surgeons caring for children with renal tumors fully understand the current standards of care in order to provide appropriate surgical expertise within this multimodal framework. Fortunately, the last 60 years of international, multidisciplinary pediatric cancer cooperative group studies have enabled high rates of cure for these patients. This review will highlight the international surgical approaches to pediatric patients with kidney cancer to help surgeons understand the key differences and similarities between the European (International Society of Pediatric Oncology) and North American (Children's Oncology Group) recommendations.

Abstract
BACKGROUND To review race and ethnic group enrollment and outcomes for Wilms tumor (WT) across all 4 risk-assigned therapeutic trials from the current era Children's Oncology Group Renal Tumor Biology and Risk Stratification Protocol, AREN03B2. STUDY DESIGN For patients with WT enrolled in AREN03B2 (2006 to 2019), disease and biologic features, therapeutic study-specific enrollment, and event-free (EFS) and overall (OS) 4-year survival were compared between institutionally reported race and ethnic groups. RESULTS Among 5,146 patients with WT, no statistically significant differences were detected between race and ethnic groups regarding subsequent risk-assigned therapeutic study enrollment, disease stage, histology, biologic factors, or overall EFS or OS, except the following variables: Black children were older and had larger tumors at enrollment, whereas Hispanic children had lower rates of diffuse anaplasia WT and loss of heterozygosity at 1p. The only significant difference in EFS or OS between race and ethnic groups was observed among the few children treated for diffuse anaplasia WT with regimen UH-1 and -2 on high-risk protocol, AREN0321. On this therapeutic arm only, Black children showed worse EFS (hazard ratio = 3.18) and OS (hazard ratio = 3.42). However, this finding was not replicated for patients treated with regimen UH-1 and -2 under AREN03B2 but not on AREN0321. CONCLUSIONS Race and ethnic group enrollment appeared constant across AREN03B2 risk-assigned therapeutic trials. EFS and OS on these therapeutic trials when analyzed together were comparable regarding race and ethnicity. Black children may have experienced worse stage-specific survival when treated with regimen UH-1 and -2 on AREN0321, but this survival gap was not confirmed when analyzing additional high-risk AREN03B2 patients.

Abstract
BACKGROUND Learning health networks (LHN) are consortia of institutions that collaborate and embrace the elements of the learning health system (LHS), including quality improvement, education, research, and stakeholder involvement. Their ultimate goal is rapid information dissemination in clinical care. Pediatric surgical specialties perform unique yet high-impact procedures that could benefit from LHN, thereby improving surgical outcomes and care through LHS approaches. Consequently, health system leaders should be aware of LHN and their importance in enhancing surgical care and improving outcomes. This scoping review aims to map and characterize the existing LHN applied in pediatric surgical specialties. METHODS A systematic literature search was performed on Medline, EMBASE, and Scopus up to June 2022, with an update search conducted in May 2023. Additionally, Google Scholar, ProQuest and inquiry from topic experts were used for cross-referencing relevant review articles to identify grey literature. This scoping review was conducted and reported according to the PRISMA-scoping review extension. RESULTS A total of 56 publications for 19 LHN were identified and included in this scoping review. Out of 19 identified LHN in pediatric surgical specialties, 18 were organized in North America. Eight of the networks are related to pediatric general surgery and another eight were related to pediatric transplantation. The 16 out of 19 LHN were initiated after 2001. To date, only eight of the LHNs generated reports of comparative improved outcomes. CONCLUSION This scoping review provides an overview of the available LHNs in pediatric surgical specialties. Over the past decade, several pediatric surgical specialties have embraced the principles of learning health systems, forming inter-institutional collaborations that utilize information technology to generate big data on patient-level clinical information, engage in quality improvement cycles, adopt evidence-based practices, and actively involve patients and stakeholders.

Abstract
PURPOSE A comprehensive operative report for cancer surgery is crucial for accurate disease staging, risk stratification, and therapy escalation/de-escalation, which affects the outcome. Narrative operative reports may fail to include some critical findings. Furthermore, standardized operative reports can form the basis of a local registry, which is often lacking in limited-resource settings (LRSs). In adult literature, synoptic operative reports (SOR) contain more key findings than narrative operative reports. In the LRSs, where the capacity of diagnostic pathology services is typically suboptimal, the value of a thorough operative report is even greater. The aim of this study was to develop a SOR template to help standardize childhood cancer surgery reporting in LRSs. METHODS Twenty-three experts in pediatric cancer with extensive experience practicing in LRSs were invited to participate in a modified Delphi procedure. SOR domains for pediatric oncology surgery were drafted based on a literature search and then modified based on experts' opinions. The experts anonymously answered multiple rounds of online questionnaires until all domains and subdomains reached a consensus, which was predefined as 70% agreement. RESULTS Sixteen experts participated in the study, and two rounds of the survey were completed. Twenty-one domains were considered relevant, including demographics, diagnosis, primary site, preoperative disease stage, previous tumor biopsy or surgery, preoperative tumor rupture, neoadjuvant therapy, surgical access, type of resection, completeness of resection, tumor margin assessment, locoregional tumor extension, organ resection, intraoperative tumor spillage, vascular involvement, lymph node sampling, estimated blood loss, intraoperative complications and interventions to address them, specimen names, and specimen orientation. CONCLUSION We developed a SOR template for pediatric oncology surgery in LRSs. Consensus for all 21 domains and associated subdomains was achieved using a modified Delphi procedure.

Abstract
PURPOSE Although Children's Oncology Group renal tumor protocols mandate lymph node sampling during extirpative surgery for pediatric renal tumors, lymph node sampling is often omitted or low yield. Concerns over morbidity associated with extended lymph node sampling have led to hesitancy in adopting a formal lymph node sampling template. We hypothesized that complications in children undergoing lymph node sampling for renal tumors would be rare, and not associated with the number of lymph nodes sampled. MATERIALS AND METHODS A single-institution, retrospective review of patients aged 0-18 years undergoing extirpative renal surgery with lymph node sampling for a suspected malignancy between 2005 and 2019 was performed. Patients with 0 or an unknown number of lymph nodes sampled or <150 days of follow-up were excluded. A "clinically significant" complication was defined as any Clavien complication ≥III, small-bowel obstruction, chylous ascites, organ injury, or wound infection. The number of lymph nodes sampled and its influence on the odds of experiencing a clinically significant complication was examined. RESULTS A total of 144 patients met inclusion criteria. Median patient age was 38 months. Twenty-one patients (15%) had a clinically significant complication, the most common of which was ileus/small-bowel obstruction (n=16). In a multivariable analysis, increased lymph node yield was not found to influence the odds of experiencing a clinically significant complication (P = .6). CONCLUSIONS In this cohort, there was no statistically significant difference in clinically significant complications in patients who underwent more extensive lymph node sampling during surgery for a suspected malignant pediatric renal tumor. Future studies on protocol adherence, staging accuracy, and survival trends using a lymph node sampling template in these patients should be performed.

Abstract
Surgery is one of the cornerstones of Wilms tumor treatment. In this article, we present technical advancements that are finding their way into the armamentarium of pediatric cancer surgeons. We discuss the current approaches, challenges, opportunities, and future directions of minimally invasive surgery (laparoscopic and robotics), image-guided surgery, and fluorescence-guided surgery. Furthermore, we discuss the use of intraoperative ultrasonography, as well as the use of new techniques to improve the quality of lymph node sampling.

Abstract
In the United States, more than 10 000 cancers occur annually in children aged 0-14 years, and more than 5000 in adolescents aged 15-19. In the last 50 years, significant advances have been made in imaging, molecular pathology, stage and risk assessment, surgical approach, multidisciplinary treatment, and survival for pediatric solid tumors (particularly neuroblastoma, Wilms tumor, rhabdomyosarcoma, and hepatoblastoma). Moreover, the molecular driver for fibrolamellar hepatocellular carcinoma, which occurs in adolescence and young adulthood, has been identified.

Abstract
Outcomes have improved significantly over the last 60 years for children with cancer. However, one consequence of improved survival is that many patients are now living with the long-term consequences of therapy. Pediatric surgeons can impact both the oncologic outcomes and morbidities of therapy. Therefore, it is incumbent upon us to be considerate, informed, and introspective about what we do as surgeons.

Abstract
Introduction: Despite remarkable improvement in Wilms' tumor (WT) survival in Western world, sub-optimal outcome in resource-constrained settings is influenced by late presentation, larger size, and poor access to treatment. This prompted us to study the outcome at a tertiary care center and to identify the global and local practice gaps. Materials and Methods: A retrospective, observational study of WT was conducted from October 2009 to September 2019 at a tertiary care setting. Following the National Wilms' Tumor Study Group protocol, an upfront nephrectomy (unilateral resectable tumors) and preoperative chemotherapy (large/unresectable Stage I–III) were followed. The records were reviewed for demographics, stage, preoperative chemotherapy, predictive factors, and outcome. Survival curves were plotted by the Kaplan–Meier method, and analysis was performed using the SPSS software version 16. Results: One hundred and fifty-six children were included, median age was 4.1 years, with a male predominance. The most common stages of the presentation were II (40.4%) and III (34.6%). An upfront surgery was done in 27.6%, while remaining received preoperative chemotherapy. The median follow-up was 22 months, and the events included relapse in 46 (29.48%) and death in 54 (34.61%). The mean survival time was 45.7 (95% confidence interval [CI], 41.08–50.30). The 2-year overall survival was 65.38% (95% CI, 59–73), and the 2-year event-free survival was 36% (95% CI, 32–41). On comparison of the impact of preoperative chemotherapy, the survival estimates in Stages I–III and relapse rate were statistically similar, tumor size reduced significantly, and tumor spill was significantly lower (P < 0.05). Conclusion: WT is associated with late presentation, sub-optimal survival, and higher relapse in our setting associated with practice gaps related to the management including practice violations.

Abstract
Wilms tumour (WT) is a childhood embryonal tumour that is paradigmatic of the intersection between disrupted organogenesis and tumorigenesis. Many WT genes play a critical (non-redundant) role in early nephrogenesis. Improving patient outcomes requires advances in understanding and targeting of the multiple genes and cellular control pathways now identified as active in WT development. Decades of clinical and basic research have helped to gradually optimize clinical care. Curative therapy is achievable in 90% of affected children, even those with disseminated disease, yet survival disparities within and between countries exist and deserve commitment to change. Updated epidemiological studies have also provided novel insights into global incidence variations. Introduction of biology-driven approaches to risk stratification and new drug development has been slower in WT than in other childhood tumours. Current prognostic classification for children with WT is grounded in clinical and pathological findings and in dedicated protocols on molecular alterations. Treatment includes conventional cytotoxic chemotherapy and surgery, and radiation therapy in some cases. Advanced imaging to capture tumour composition, optimizing irradiation techniques to reduce target volumes, and evaluation of newer surgical procedures are key areas for future research.

Abstract
Background: Wilms’ tumor (nephroblastoma) is the major renal cancer in children. Objectives: The aim of this study was to assess the individuality of Wilms’ tumor and the consequences of management attained in our referral subspecialty center. Methods: In this study, we composed the data of children with Wilms’ tumor in 2 decades; 55 cases between 1992 and 2002 and 49 patients between 2006 and 2016 were diagnosed with Wilms’ tumor. Demographic characters, a form of presentation, tumor stage, related underlying disease, histopathology consequences, type of management, and the survival rates were assessed. Results: In the first decade, 24 patients were females and 31 were males (M/F = 1.2); in the other groups, 30 were females and 19 were males (M/F = 0.61). The mean age was 45.2 months at the time of diagnosis for the first group and the mean age was 36 months for the other group. In the first decade, the surgical stage after the operation was as follows: stage I (32.7%), stage II (16.36%), stage III (38.1%), stage IV (9%), and stage V (1.8%) who did not operate. In second decade, 49 patients were as follows: stage I (14.3%), stage II (40.8%), stage III (24.5%), stage IV (10.2%), and stage V (10.2%). In 54.5% of the first group, histology was favorable, and in 43.6% of the first group, histology was unfavorable; in the second group, 95.4% were the favorable type. The patients were managed based on protocols of the National Wilms’ Tumor Study. In the first decade, relapse-free was 71% and 4-year survival rates were estimated at 86%, and in the second decade, pulmonary metastasis was observed at 28.6%, liver metastasis in 2.3%, recurrence in 5%, and 4-year survival rates were estimated at 90%. Conclusions: This study demonstrated development in the management of children with Wilms’ tumor in recent 20 years, with comparable relapse-free and survival rates to the National Wilms’ Tumor study. But with more adjustment in treatment protocols, the superior outcome will be attainable.

Abstract
INTRODUCTION Minimally invasive nephrectomy (MIN)for the resection of pediatric renal tumors is controversial. We compared patients who underwent laparoscopic MIN according to our unit protocol with matched patients who underwent open surgery (ON). METHOD A single centre retrospective analysis of prospectively collected data for MIN. Tumor volume was calculated from pre-operative imaging and volume matched ON patients were identified from the regional tumor database. Demographics, complications, operative time, length of stay, number of nodes resected, status of margins, radiotherapy (RT)requirement, length of follow-up and outcomes were analysed. RESULTS Fourteen MINs performed between September 2016 and 11/2019 (M:F 5:9; median age 37 (range 2-73)months) were matched with ON controls (7:7 M:F, median age 42 (1-74)months). Diagnoses in the MIN group were Wilms Tumour (WT)in11 and one each of mesoblastic nephroma (MN), malignant rhabdoid tumour of the kidney (MRTK), nephroblastomatosis and in the ON group were 13 WT and 1 MN. Median operating time for MIN was 180 (125-300)minutes, with 4 conversions and 155 (1-3-480)minutes in ON. There were no intra-operative ruptures. Three tumors in each group had positive margins. A median of 4 (0-6) nodes were removed during MIN and 4 (2-22) during ON. Median length of stay (LoS)was 4 (2-15)days following MIN and 4 (2-9) following MIN. Six ON and 3 MIN patients required radiotherapy. Differences were not significant. Median follow up of 30 (6-44)months for MIN and 73 (34-109)months for ON patients was significantly different. There have been no local recurrences but the child with MRTK died following brain tumor recurrence. CONCLUSION MIN for pediatric renal tumors has similar short term outcomes to ON in carefully selected patients.

Abstract
Abstract
Background
Wilms tumor is the commonest malignant renal neoplasm in children. Surgery plays a pivotal role in the management, and evidence-based guidelines for surgical resection have been established by the major international groups. Any deviation from the protocol is considered as a violation. The goal of this study was to evaluate outcomes of the patients with unilateral Wilms tumor treated at a developing country and to analyze surgical violations (SV) and their impact on the prognosis. A retrospective review was conducted for 37 patients who were presented to our hospitals and underwent nephrectomy for WT from January 2016 to December 2018. All participating centers adopt Children’s Oncology Group protocol. The SV were analyzed by logistic regression. Overall survival (OS) and event-free survival (EFS) were estimated by the Kaplan-Meier method.
Results
There were 12 (32.4%), 11 (29.7%), 10 (27%), and 4 (10.8%) stages I, II, III, and IV, respectively. Their median age at time of diagnosis was 3.1 years. Upfront nephrectomy was performed for 30 cases. Six patients had tumor relapse (2 lungs and 4 local recurrences) at a median follow-up of 15.7 months. Out of the relapsed patients, two had unfavorable histology, and regarding their staging, four were stage III, one was stage II, and one was stage IV. Thirty-month OS and EFS were 84.3% and 81.1%, respectively. Twenty-seven SV occurred within 25 patients. Lack or inadequate lymph node sampling represented 74.07% (20/27), intraoperative tumor rupture and spillage accounted for 18.52% (5/27), and unwarranted preoperative biopsy happened in 7.41% (2/27). The SV were not correlated with mortality (p value = 0.381); however, they had a significant impact on the relapse (p value = 0.001). On further analysis; tumor rupture and spillage was a predictor for recurrence reaching a statistical significance (p value = 0.003), whereas the other violations were not.
Conclusions
Favorable outcomes could be achieved by compliance with evidence-based guidelines even in a resource-limited country like ours. Violations were correlated with relapse; however, only tumor rupture and spillage was of statistical significance in multivariate analysis. Failure of lymph node documentation was the main problem encountered, and it should be avoidable in future practice.

Abstract
The advances in pediatric cancer far exceed those achieved in adults. The success in improving survival and minimizing late effects has been due to several reasons but work of the pediatric cancer cooperative groups is a primary. These cooperative groups are multidisciplinary with medical oncologists, pathologists, radiologists, surgeons, radiation oncologists, scientists and most importantly the patients and families. Studies have expanded from regional to national and now international studies which continue to target problems pertinent to improving the outcome for children with cancer. In this article we review the history of the cooperative groups, a selection of seminal studies pertaining to solid tumors, future challenges and collaborations.

Abstract
PURPOSE In National Wilms Tumor Study 5 (NWTS-5), tumor-specific combined loss of heterozygosity of chromosomes 1p and 16q (LOH1p/16q) was associated with adverse outcomes in patients with favorable histology Wilms tumor. The AREN0533/AREN0532 studies assessed whether augmenting therapy improved event-free survival (EFS) for these patients. Patients with stage I/II disease received regimen DD4A (vincristine, dactinomycin and doxorubicin) but no radiation therapy. Patients with stage III/IV disease received regimen M (vincristine, dactinomycin, and doxorubicin alternating with cyclophosphamide and etoposide) and radiation therapy. METHODS Patients were enrolled through the AREN03B2 Biology study between October 2006 and October 2013; all underwent central review of pathology, surgical reports, and imaging. Tumors were evaluated for LOH1p/16q by microsatellite testing. EFS and overall survival were compared using the log-rank test between NWTS-5 and current studies. RESULTS LOH1p/16q was detected in 49 of 1,147 evaluable patients with stage I/II disease (4.27%) enrolled in AREN03B2; 32 enrolled in AREN0532. LOH1p/16q was detected in 82 of 1,364 evaluable patients with stage III/IV disease (6.01%) in AREN03B2; 51 enrolled in AREN0533. Median follow-up for 83 eligible patients enrolled in AREN0532/0533 was 5.73 years (range, 2.84 to 9.63 years). The 4-year EFS for patients with stage I/II and stage III/IV disease with LOH1p/16 was 87.3% (95% CI, 75.1% to 99.5%) and 90.2% (95% CI, 81.8% to 98.6%), respectively. These results are improved compared with the NWTS-5 updated 4-year EFS of 68.8% for patients with stage I/II disease (P = .042), and 61.3% for patients with stage III/IV disease (P = .001), with trends toward improved 4-year overall survival. The most common grade 3 or higher nonhematologic toxicities with regimen M were febrile neutropenia (39.2%) and infections (21.6%). CONCLUSION Augmentation of therapy improved EFS for patients with favorable histology Wilms tumor and LOH1p/16q compared with the historical NWTS-5 comparison group, with an expected toxicity profile.

Abstract
OBJECTIVES According to the Renal Tumor Study Group (RTSG) of the International Society of Paediatric Oncology (SIOP), diagnostic biopsy of renal tumors prior to neoadjuvant chemotherapy is not mandatory unless the presentation is atypical for a Wilms tumor (WT). This study addresses the relevance of this strategy as well as the accuracy and safety of image-guided needle biopsy. METHODS Clinical, radiological, and pathological data from 317 children (141 males/176 females, mean age: 4 years, range, 0-17.6) consecutively treated in one SIOP-affiliated institution were retrospectively analyzed. RESULTS Presumptive chemotherapy for WT was decided for 182 patients (57% of the cohort), 24 (8%) were operated upfront, and 111 (35%) were biopsied at diagnosis. A non-WT was confirmed after surgery in 5/182 (3%), 11/24 (46%), and 28/111 (25%), respectively. Age at diagnosis was the most commonly (46%) used criterion to go for biopsy but a nine-year threshold should be retrospectively considered more relevant. Tumor volumes of clear cell sarcoma of the kidney and WT were significantly higher than those of other tumors (P = 0.002). The agreement between core-needle biopsy (CNB) and final histology was 99%. No significant morbidity was associated with CNB. CONCLUSION The use of SIOP criteria to identify patients eligible for presumptive WT neoadjuvant chemotherapy or upfront surgery avoided biopsy in 65% of children and led to a 97% rate of appropriate preoperative chemotherapy. Image-guided CNB is a safe and accurate diagnostic procedure. The relevance of SIOP biopsy criteria might be improved by using an older age threshold (9 years instead of 6 years) and by adding initial tumor volume.

Abstract
This study aims to investigate the management of Wilms tumor by the Egyptian pediatric surgical association (EPSA) consultants. After approval of the EPSA executive board, a questionnaire was distributed individually to all consultants attending the general assembly of EPSA 2017 annual congress. Of 88 consultants, responses were received from 61. Palpable abdominal mass was indicated by 72.13% of respondents as the commonest presenting symptom. Concerning the imaging requested, computed tomography was reported by 80.33%. Approximately 62.30% of respondents perform 1 to 3 cases annually. Regarding timing of surgery, upfront resection was the most frequently reported by 62.30%. A total of 77.05% perform lymph node sampling during surgeries. Nephron-sparing surgery was adopted by only 26.23%, whereas none of the respondents reported the use of minimally invasive surgery for management. Overall, 93.44% of surgeons ask for a visit every 3 months in the first year postoperatively. Upfront nephrectomy is the commonest procedure for Wilms tumor in the current practice of EPSA consultants, whereas there is consensus against minimally invasive surgery. Surgical guidelines for nephron-sparing surgery are still incomplete and need to be tabulated. This study urges for a nationwide retrospective analysis to establish a uniform protocol with international reference to be adopted in Egypt.

Abstract
Purpose The National Wilms Tumor Study (NWTS) treatment of favorable histology Wilms tumor with lung metastases was vincristine/dactinomycin/doxorubicin (DD4A) and lung radiation therapy (RT). The AREN0533 study applied a new risk stratification and treatment strategy to improve event-free survival (EFS) while reducing exposure to lung RT. Methods Patients with favorable histology Wilms tumor and isolated lung metastases showing complete lung nodule response (CR) after 6 weeks of DD4A continued receiving chemotherapy without lung RT. Patients with incomplete response (IR) or loss of heterozygosity at chromosomes 1p/16q received lung RT and four cycles of cyclophosphamide/etoposide in addition to DD4A drugs (Regimen M). AREN0533 was designed to preserve a 4-year EFS of 85% for lung nodule CR and improve 4-year EFS from 75% to 85% for lung nodule IR. Results Among 292 assessable patients, 133 had CR and 159 had IR. For patients with CR, 4-year EFS and overall survival (OS) estimates were 79.5% (95% CI, 71.2% to 87.8%) and 96.1% (95% CI, 92.1% to 100%), respectively. Expected versus observed event rates were 15% and 20.2% ( P = .052), respectively. For patients with IR, 4-year EFS and OS estimates were 88.5% (95% CI, 81.8% to 95.3%) and 95.4% (95% CI, 90.9% to 99.8%), respectively. Expected versus observed event rates were 25% and 12.2% ( P < .001), respectively. Overall, 4-year EFS and OS were 85.4% (95% CI, 80.5% to 90.2%) and 95.6% (95% CI, 92.8% to 98.4%) compared with 72.5% (95% CI, 66.9% to 78.1%; P < .001) and 84.0% (95% CI, 79.4% to 88.6%; P < .001), respectively, in the predecessor NWTS-5 study. Conclusion Excellent OS was achieved after omission of primary lung RT in patients with lung nodule CR, although there were more events than expected. EFS was significantly improved, with excellent OS, in patients with lung nodule IR using four cycles of cyclophosphamide/etoposide in addition to DD4A drugs. The overall AREN0533 treatment strategy yielded EFS and OS estimates that were superior to previous studies.

Current state of renal tumor surgery among pediatric surgeons and pediatric urologists: A survey of American Pediatric Surgical Association (APSA) and Society for Pediatric Urology (SPU) members. J Pediatr Urol 2018; 14:168.e1-168.e8. [PMID: 29246796 DOI: 10.1016/j.jpurol.2017.11.005] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/09/2017] [Accepted: 11/15/2017] [Indexed: 11/30/2022]
Abstract
INTRODUCTION Anecdotally, renal tumor (RT) surgery makes up a limited portion of the practice for most pediatric urologists and pediatric surgeons. Data are lacking on the current perceptions of RT surgery, both volume of surgery and issues related to surgical practice, among pediatric surgeons (PS) and pediatric urologists (PU). OBJECTIVES To describe practice patterns of pediatric renal tumor (RT) surgery and identify factors related to higher reported volumes of RT surgery. STUDY DESIGN The survey was developed and pilot-tested by the Children's Oncology Group (COG) RT surgery committee. The survey was distributed to APSA and SPU members. Logistic regression was performed to correlate surgeon-reported factors with higher reported volumes of RT surgery. RESULTS The survey was sent to 1,282 APSA and 426 SPU members, 367 (21.5%) surveys were completed from eligible responders, 244 (65.2%) and 123 (32.9%) from APSA and SPU invitations, respectively. Overall, 33.9% reported being part of a practice group in which RT surgical care is sub-specialized. A majority (50.7%) of respondents reported personally performing one to two RT surgeries annually, and 16.7% reported performing none. Multivariate logistic regression identified the following significant factors associated with increased individual RT surgical volume: group sub-specialization, COG/SIOP membership, regular tumor board attendance, and annual institutional volume >10 RT surgeries (Table). Accurate responses on the need for lymph node (LN) sampling in RT surgery were reported by 89.9%. Overall, 15.8% and 24.5% of respondents failed to correctly correlate local stage III disease in Wilms tumor (WT) with open or percutaneous biopsy, respectively (p < 0.001). DISCUSSION While we found that reported RT surgery volume is low among both pediatric urologists and surgeons, we did identify surgeon-specific factors which correlated with higher RT surgical volume. Interested pediatric urologists and surgeons may use these data to tailor their practice if their goal is to increase RT surgery volume. Additionally, based on less than ideal rates of correct responses to nuance in the staging and treatment of WT, there are clear opportunities to increase education in this content area. However, the study is limited by use of a non-validated survey instrument and the relatively low response rates. CONCLUSION Reported individual RT surgery volume is low. Factors associated with increased volume include sub-specialty practice, tumor board involvement, and higher institutional volume. Responses on LN sampling and biopsy in WT demonstrate opportunities for educational initiatives.

Imaging of renal medullary carcinoma in children and young adults: a report from the Children's Oncology Group. Pediatr Radiol 2017; 47:1615-1621. [PMID: 28689245 PMCID: PMC5768308 DOI: 10.1007/s00247-017-3926-6] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/15/2017] [Revised: 04/25/2017] [Accepted: 06/09/2017] [Indexed: 12/23/2022]
Abstract
BACKGROUND Renal medullary carcinoma is a rare renal malignancy of childhood. There are no large series describing the imaging appearance of renal medullary carcinoma in children. OBJECTIVE To characterize the clinical and imaging features of pediatric renal medullary carcinoma at initial presentation. MATERIALS AND METHODS We retrospectively analyzed images of 25 pediatric patients with renal medullary carcinoma enrolled in the Children's Oncology Group renal tumors classification, biology and banking study (AREN03B2) from March 2006 to August 2016. Imaging findings of the primary mass, and patterns of locoregional and distant spread were evaluated in correlation with pathological and surgical findings. RESULTS Median age at presentation was 13 years (range: 6-21 years), with a male predominance (3.2:1). The overall stage of disease at initial presentation was stage 1 in 1, stage 2 in 2 and stage 4 in 22. Maximum diameter of the primary renal mass ranged from 1.6 to 10.3 cm (mean: 6.6 cm) with a slight right side predilection (1.5:1). Enlarged (>1 cm short axis) retroperitoneal lymph nodes were identified at initial staging in 20/25 (80%) cases, 10 of which were histologically confirmed while the others did not undergo surgical sampling. Enlarged lymph nodes were also identified in the mediastinum (14/25; 56%) and supraclavicular regions (4/25; 16%). Metastatic disease was present in the lungs in 19/25 (76%) and liver in 6/25 (24%). The pattern of lung metastases was pulmonary lymphangitic carcinomatosis: 10 cases (9 bilateral, 1 unilateral), pulmonary nodules with indistinct margins: 6 cases, pulmonary nodules with distinct margins: 2 cases, while 1 case had pulmonary nodules with both indistinct and distinct margins. Pulmonary lymphangitic carcinomatosis was pathologically confirmed in 4/10 cases. All cases with pulmonary lymphangitic carcinomatosis had associated enlarged mediastinal lymph nodes. CONCLUSION Renal medullary carcinoma in children and young adults presents at an advanced local and distant stage in the majority of patients. The diagnosis of renal medullary carcinoma should be considered when a child or young adult presents with a poorly defined/infiltrative, centrally located renal mass, especially in the setting of known sickle cell hemoglobinopathy. Distant metastases are common at initial presentation in the lungs, distant lymph nodes and liver and often involve multiple sites simultaneously. Pulmonary lymphangitic carcinomatosis, a distinctive and uncommon form of lung metastasis in children, is common in this patient population.

Reliability of intraoperative frozen section for the diagnosis of renal tumors suspicious for malignancy in children and adolescents. Pediatr Blood Cancer 2017; 64:10.1002/pbc.26458. [PMID: 28097784 PMCID: PMC5509572 DOI: 10.1002/pbc.26458] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2016] [Revised: 12/14/2016] [Accepted: 12/25/2016] [Indexed: 11/10/2022]
Abstract
BACKGROUND The ability of intraoperative frozen section (IFS) to reliably diagnose renal tumors in children and adolescents is largely unknown. The objective of our study is to evaluate the ability of IFS to establish a histologic diagnosis for renal tumors in this population. METHODS We reviewed our experience with patients who underwent IFS at the time of surgery for a renal tumor suspicious for malignancy from 2005 to 2015. The IFS was compared to the final pathology (FP). Data on concordance and reliability were analyzed. RESULTS One hundred thirty patients underwent surgical interventions for a renal tumor suspicious for malignancy, and 32 (25%) patients underwent IFS. Median turnaround time for IFS was 20 min (range 13-44). The histologic IFS diagnosis correlated with FP in 26 (81.2%) cases was discrepant in three (9.4%) cases, and IFS was deferred to FP in three (9.4%) cases (kappa 0.71, 95% confidence interval [CI]: 0.52-0.899, P < 0.001). The IFS correctly distinguished between Wilms tumor and non-Wilms tumor in 30 (94%) cases (kappa 0.874, 95% CI: 0.705-1, P < 0.001). A total of 17 of 19 (89.5%) Wilms tumors were correctly diagnosed by IFS, yielding a sensitivity of 0.89 (95% CI: 0.67-0.99) and a specificity of 1 (95% CI: 0.75-1). CONCLUSION IFS is a reliable tool to establish a histologic diagnosis and to differentiate between Wilms and non-Wilms tumors in children and adolescents with renal tumors. The use of IFS should be encouraged in cases in which obtaining a diagnosis will provide guidance for important "real-time" medical decision making, specifically additional adjunctive surgical procedures.

Abstract
PURPOSE Objective data on patterns of oncology practice among pediatric urologists are lacking. We reviewed surgical case logs submitted to the American Board of Urology by those self-reporting as pediatric urologists. We hypothesized that logs would reveal a low oncology volume (fewer than 5 cases) and identify orchiectomy as the most common oncology cases, and that less than 25% of logs would show nephrectomy for renal tumor. MATERIALS AND METHODS Case logs submitted for American Board of Urology certification, recertification or pediatric subspecialty certification were reviewed and standardized to represent 12-month practice. Data were collected on pediatric oncologic surgeries as noted by procedure codes linked with oncologic diagnosis codes for patients up to age 30 years. RESULTS We identified 281 case logs meeting study criteria. A total of 364 oncology cases were logged and 131 logs (46.6%) listed at least 1 oncology case, while 150 (53.4%) contained no oncology cases. The 75th, 90th and 95th percentiles of oncology volume were represented by reporting 2, 3 and 4 cases, respectively. A total of 13 logs (4.6%) accounted for more than a third of all oncology cases (35.9%). The most frequent oncology case logged was orchiectomy, which was documented in 83 logs (29.5%). On Poisson regression surgeon variables associated with higher oncology volume included male gender (IRR 2.8, 95% CI 2.1-3.9), 2010 log year (IRR 2.4, 95% CI 1.3-4.4), 2015 log year (IRR 3.7, 95% CI 2.1-6.4) and nonpediatric subspecialty certification log (IRR 1.6, 95% CI 1.2-2.3). CONCLUSIONS Few pediatric urologists perform a high volume of oncologic surgeries based on surgical case logs submitted to the American Board of Urology. A small cohort of pediatric urologists logged the majority of such cases.

Abstract
With improvement in the outcomes for children with cancer has come an increasing focus on minimizing the morbidity from therapeutic interventions, including surgical procedures, while continuing to have a high likelihood of cure. Thus, an appreciation for the potential complications of surgery, both acute and long term, is critical when considering the risks and benefits of any procedure performed on a child with cancer. Although not meant to be an exhaustive review, here we discuss the most common and significant surgical complications that may occur when performing diagnostic, therapeutic, or supportive procedures in children with the most common malignant solid tumors.

Abstract
Despite an impressive increase in survival rate over the past decades, there is still a need to improve the survival of specific subgroups of Wilms tumor (anaplastic, metastatic, and bilateral) and to decrease the late effects of treatment in terms of renal function and heart toxicity. We aim to explore new areas of improvement, from diagnosis to treatment: in the field of radiology the increased use of MRI and exploration of its diffusion-weighted imaging capabilities to predict WT histology at diagnosis and for preoperative assessment; in biology the emergence of new biomarkers that could be integrated into the decision-making process; and surgical techniques with more accurate indication of nephron-sparing surgery that is no longer reserved for bilateral WT and the minimally invasive approach. The long-term outcome of patients with WT should thus be a strong indicator of the improvement in adapting and personalizing the treatment to each individual.
