Major surgical conditions of childhood and their lifelong implications: comprehensive review. BJS Open 2024; 8:zrae028. [PMID: 38776252 PMCID: PMC11110943 DOI: 10.1093/bjsopen/zrae028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2023] [Revised: 12/18/2023] [Accepted: 01/30/2024] [Indexed: 05/24/2024] Open
Abstract
BACKGROUND In recent decades, the survival of children with congenital anomalies and paediatric cancer has improved dramatically such that there has been a steady shift towards understanding their lifelong health outcomes. Paediatric surgeons will actively manage such conditions in childhood and adolescence, however, adult surgeons must later care for these 'grown-ups' in adulthood. This article aims to highlight some of those rare disorders encountered by paediatric surgeons requiring long-term follow-up, their management in childhood and their survivorship impact, in order that the adult specialist may be better equipped with skills and knowledge to manage these patients into adulthood. METHODS A comprehensive literature review was performed to identify relevant publications. Research studies, review articles and guidelines were sought, focusing on the paediatric management and long-term outcomes of surgical conditions of childhood. The article has been written for adult surgeon readership. RESULTS This article describes the aforementioned conditions, their management in childhood and their lifelong implications, including: oesophageal atresia, tracheo-oesophageal fistula, malrotation, short bowel syndrome, duodenal atresia, gastroschisis, exomphalos, choledochal malformations, biliary atresia, Hirschsprung disease, anorectal malformations, congenital diaphragmatic hernia, congenital lung lesions and paediatric cancer. CONCLUSION The increasing survivorship of children affected by surgical conditions will translate into a growing population of adults with lifelong conditions and specialist healthcare needs. The importance of transition from childhood to adulthood is becoming realized. It is hoped that this timely review will enthuse the readership to offer care for such vulnerable patients, and to collaborate with paediatric surgeons in providing successful and seamless transitional care.

Characteristics and Clinical Outcomes of Children With Wilms' Tumour: A 15-year Experience in a Single Centre in Nigeria. J Pediatr Surg 2024; 59:1009-1014. [PMID: 38184433 DOI: 10.1016/j.jpedsurg.2023.12.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/16/2023] [Revised: 12/03/2023] [Accepted: 12/09/2023] [Indexed: 01/08/2024]
Abstract
BACKGROUND Wilms' tumor (WT) is the most common paediatric renal tumor and is one of the most treatment-responsive solid tumours. Survival from Wilms tumour (WT) in sub-Saharan Africa remains dismal as a result of late presentation, treatment abandonment and infrastructure deficit. The purpose of this study was to analyze the clinical outcome of children with Wilms tumour managed in a Nigerian referral centre over a 15-year period. METHODS This is a retrospective study of children with WT (nephroblastoma) who were treated at our institution between January 2006 and December 2020. Clinical characteristics, treatments, and outcomes were analyzed. RESULTS Thirty-five patients were identified. The median age at diagnosis was 36 months including 22 (62.9 %) females. Twenty-six (74.3 %) had advanced (stage III & IV) disease. Confirmatory histology was available for 16 patients ((45.7 %) among which 10 (62.5 %) were mixed type. The right kidney was affected in 18 patients (51.4 %), left in 15 (42.9 %) and 2 were not documented. Preoperative chemotherapy was given in 22 (62.9 %) patients and 13 (37.1) patients had primary nephrectomy. Eight (22.9 %) patients died during treatment (from disease or treatment related causes), and one abandoned treatment. A total of 26 patients completed treatment. Out of these, 8 (30.8 %) were lost to follow up, four patients died and 14 (53.8 %) patients survived at a median follow-up period of 18 months. The survival decreased with advancing stages of the disease, p = 0.002. CONCLUSIONS Majority of children with Wilms tumour in our practice presented with advanced disease. Death during treatment, treatment abandonment and lost to follow up were common. LEVEL OF EVIDENCE Level II. TYPE OF STUDY Retrospective Study.

Prognostic impact of pre-referral tumor resection in unilateral Wilms tumor: A single-institute experience from a lower middle-income country. Pediatr Blood Cancer 2024; 71:e30760. [PMID: 37962283 DOI: 10.1002/pbc.30760] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/04/2023] [Revised: 09/09/2023] [Accepted: 10/20/2023] [Indexed: 11/15/2023]
Abstract
INTRODUCTION The objectives of this study were to evaluate the prognostic impact of pre-referral surgical resection of Wilms tumor (WT) performed at non-oncology centers, and to strategize an improved care plan for this very curable pediatric tumor. METHODS In this study conducted in a large pediatric cancer center in Pakistan, we retrospectively reviewed the electronic medical records (EMR) of 149 patients with unilateral WT from September 2008 to August 2017. Based on treatment approach, patients were categorized into two groups: (i) pre-referral tumor resection (PTR: n = 75), and (ii) post-neoadjuvant chemo nephrectomy (PCN: n = 74). RESULTS The proportion of metastatic disease in PTR and PCN groups was 33.3% and 35.1%, respectively. In the PTR subset, median time to admission after PTR was 5 weeks (mean 11, SEM 2.8, range: 2-202) weeks, with 53.3% (n = 40) presenting more than 4 weeks after PTR. Twenty patients had no cross-sectional imaging prior to PTR and underwent surgery after abdominal ultrasound only. On baseline imaging at our center, 58.7% (n = 44) of the PTR group had radiologically evaluable disease (four metastases only, 19 local residual tumor only, 21 both localized tumor and visible metastases). Disease staging was uncertain in 23 patients because of no or inadequate histology specimens and/or lymph node sampling in patients with no evaluable disease. Statistically significant differences were recorded for the two subsets regarding tumor volume, extent and nodularity, renal vein and renal sinus involvement, lymph node status, tumor rupture and histopathologic features, and tumor stage, with a 10-year event-free survival (EFS) for PCN and PTR of 74.3% and 50.7%, respectively (p < .001). In the PTR group, EFS for those presenting within 4 weeks and later was 91.4% versus 15.0%, respectively (p < .0001). CONCLUSION Suboptimal pre-referral surgical intervention results in poor survival outcomes in unilateral WT. Our findings highlight the need for a comprehensive action plan for educating healthcare professionals engaged in WT diagnosis and referral process. PCN in a multidisciplinary team approach can reduce surgical morbidity and seems to be a better strategy to improve the survival rates in low-resource settings.

Grossing to reporting of Wilms tumor with emphasis on proper sampling in treatment-naive and postchemotherapy specimens and their clinicopathological correlation with outcome. Urol Ann 2024; 16:87-93. [PMID: 38415234 PMCID: PMC10896324 DOI: 10.4103/ua.ua_60_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2023] [Accepted: 10/31/2023] [Indexed: 02/29/2024] Open
Abstract
Context Emphasis on grossing to reporting for the assessment of histopathological parameters predicting outcomes in Wilms tumor. Aims To analyze various clinicopathological parameters that effect outcomes in treatment naïve and post chemotherapy Wilms tumor specimens. Settings and Design This was a retrospective observational study. Subjects and Methods All patients diagnosed with Wilms tumor between 2012 and 2018 at our institute will be included with their clinical findings, laboratory reports, and radiological findings. The patients will be categorized into two groups based on treatment protocol (Society of Pediatric Oncology (SIOP) or the National Wilms Tumor Study Group/Children's Oncology Group (COG) guidelines) used. Details of Grossing and reporting protocols used for the in pre treatment and post treatment specimens will be analyzed. Follow-up till December 2020 will be analyzed. Statistical Analysis Used Chi-square and Fisher's exact tests were used for statistical analysis. Results A total of 36 patients with the diagnosis of Wilms tumor were included in the present study. The mean age of presentation was 3.9 ± 0.7 years, and males were more common than females. Most of them presented as abdominal mass and few with isolated hematuria. Twenty-six (72%) patients were treated under SIOP protocol with preoperative neoadjuvant chemotherapy. Ten patients underwent upfront surgery as per COG protocol. In SIOP group patients, the mean tumor size was 9.3cm. Forty percent (n = 10) we mixed histological type followed by blastemal type constituting (32%, n = 8). Regressive and epithelial histological types constituted 16% (n = 4) and 12% (n = 3), respectively. In the SIOP group 72% (n = 19) had no anaplasia and 28% (n = 7) had anaplasia. Fifty seven percent (n = 15) cases were Stage I, followed by 26.9% n = 7) and 11.5% (n = 3) being Stage II and Stage III, respectively. Ten patients underwent upfront surgery as per COG protocol. The mean tumor size among this group was 8 cm ranging from 7 cm to 11 cm. Eight (80%) cases had favorable histology and two cases showed focal anaplasia. Heterologous differentiation is seen in 3 (70%). Out of the 10 cases, one case was Stage I, six were Stage 2, one was Stage III, and two were clinical Stage IV. None of the cases showed either vessel or lymph node metastasis. All the patients received adjuvant chemotherapy postsurgery and were followed up till December 2020 for (at least 3 years). Of 25 patients in the SIOP group, 18 (72%) had complete remission with no radiological evidence of residual disease. Of the 10 patients in the COG group, 6 (70%) had complete remission. Conclusions Histopathological evaluation of Wilms tumor is a critical aspect in the management of Wilms tumor, as tumor characteristics are different in the tumors treated under SIOP and COG protocols, which will ultimately affect the prognostic risk stratification. This necessitates the knowledge of the important grossing and reporting of these tumors under the two protocols.

Unexpected Huge Prevalence of Intracardiac Extension of Wilms Tumor—A Single Center Experience from a Ugandan Hospital. CHILDREN 2022; 9:children9050743. [PMID: 35626920 PMCID: PMC9139773 DOI: 10.3390/children9050743] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/10/2022] [Revised: 05/16/2022] [Accepted: 05/17/2022] [Indexed: 11/16/2022]
Abstract
Wilms tumor (WT) is the most common primary renal malignancy in young children. WT vascular extension to the inferior vena cava (IVC) occurs in 4–10% of cases and can reach the right atrium (RA) in 1%. Data on WT clinical presentation and outcome in developing countries are limited. The aim of the present study is to describe the prevalence of intracardiac extension in a consecutive population of WT patients observed in a large non-profit Ugandan hospital. A total of 16 patients with a histological diagnosis of 29 WT were screened in a 6-month period. Patient n°2, a 3 y/o child, presented with a 3-week history of abdominal distension, difficulty in breathing, and swelling of the lower limbs. A cardiovascular system exam showed rhythmic heart sounds, a heart rate of 110 beats per minute, and a pansystolic murmur on the tricuspid area; the abdomen was grossly distended with a palpable mass in the right flank, hepatomegaly, and splenomegaly. An abdomen ultrasound showed an intra-abdominal tumor, involving the right kidney and the liver and extended to the IVC. An ultrasound guided biopsy showed a picture consistent with WT. Cardiac echo showed a huge, mobile, cardiac mass attached to the right side of the interatrial septum, involving the tricuspid valve annulus, causing a “functional” tricuspid stenosis. The patient died of cardiogenic shock 7 days after admission. Patient n°3, a 3 y/o child, presented with analogue symptoms and the same diagnosis. The cardiac echo showed a round mass in the RA. Thirteen more patients were screened with cardiac echo, showing a normal heart picture. In our limited series, we found WT cardiac extension in three patients over 16 (19%). Cardiac echo performed routinely can lead to a better staging, prognostic, and therapeutic assessment. In our setting, the intra-cardiac extension could be more frequent than previously reported and might have prognostic implications.

The Role of Ultrasonography forDiagnosing Wilms Tumor in Developing Country. Int J Hematol Oncol Stem Cell Res 2021; 15:145-151. [PMID: 35082995 PMCID: PMC8748242 DOI: 10.18502/ijhoscr.v15i3.6844] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2019] [Accepted: 12/14/2020] [Indexed: 11/24/2022] Open
Abstract
Background: Overall five-year survival rate of Wilm’s Tumor (WT) in developing countries is still poor. Delayed diagnosis is one of the contributing factors, whereas early diagnosis is an important thing for the outcome. It is caused by the WT burden in developing countries that was not comparable with the number of facilities for diagnosis and treatment. Ultrasonography (USG) is the mandatory first-line imaging modality in children with a suspected abdominal mass and an overall sensitivity of 76%. Additionally, it can be found in many health facilities at a lower cost, quick, non-invasive, and carries no risk of radiation. Therefore, the relationship between USG and histopathology should be measured. Materials and Methods: A cross-sectional study with an analytical approach was performed in pediatric (0 untill 18 year of age) renal malignancy and neuroblastoma that admitted to Dr. Hasan Sadikin Hospital, Bandung between 2015-2018. Data were collected from medical records. Statistical analyses using Fisher exact test were done to determine the significance of the relationship between USG and histopathology. Results: Forty-three samples were obtained based on inclusion criteria, such as WT (n=33), neuroblastoma (n=6), renal clear cell carcinoma (n=2) and no specific type of renal malignancy (n=2). Fisher exact test revealed no-significant relationship between USG and histopathology with p-value > 0.05 Conclusion: There is no significant relationship between USG and histopathology. Therefore, centralized unity for USG interpretation is recommended.

Impact of neoadjuvant chemotherapy on thrombus viability in patients with Wilms tumour and caval extension: systematic review with meta-analysis. BJS Open 2021; 5:6289805. [PMID: 34052849 PMCID: PMC8164777 DOI: 10.1093/bjsopen/zrab020] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2021] [Accepted: 02/19/2021] [Indexed: 11/14/2022] Open
Abstract
BACKGROUND Inferior vena cava (IVC) tumour thrombus in children with Wilms tumour is typically managed with neoadjuvant chemotherapy with the intention of achieving thrombus regression in order to minimize the risks associated with complex vascular surgery. METHODS A systematic review of Medline and Embase databases was undertaken to identify all eligible studies with reference to thrombus viability in Wilms tumour index cases with caval/cardiac extension. A meta-analysis of proportions was utilized for pooled thrombus viability data across studies. Logistic regression was used to analyse the relationship between thrombus viability and duration of chemotherapy. RESULTS Thirty-five eligible observational studies and case reports met inclusion criteria describing a total of 236 patients with thrombus viability data. The pooled proportion of patients with viable tumour thrombus after neoadjuvant chemotherapy was 0.53 (0.43-0.63). Logistic regression analysis of 54 patients receiving either a standard (4-6 weeks) or extended (more than 6 weeks) course of neoadjuvant chemotherapy resulted in an odds ratio of 3.14 (95 per cent c.i. 0.97 to 10.16), P = 0.056, with extended course therapy trending towards viable tumour thrombus. CONCLUSION Preoperative chemotherapy is successful in achieving non-viability of caval and cardiac thrombi in around 50 per cent of children, without added benefit from extended cycles of neoadjuvant chemotherapy. Risks versus benefits of extirpative vascular surgery must be considered, therefore, for these high-risk 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
BACKGROUND Wilms tumor (WT) represents around 85% of pediatric renal tumors. In high-income countries, 5-years survival of WT is above 90% but survival in developing countries is inferior. OBJECTIVE To identify the predictors of treatment outcome of WT in a developing country. METHODS A retrospective study conducted at the pediatric oncology department, Combined Military Hospital Rawalpindi, Pakistan. All newly diagnosed WT cases from 1st January 2012 who completed their treatment before 31st August 2019 were evaluated. Treatment was based on SIOP Wilms Tumour 2001/UK version 5. Patients presenting before nephrectomy received pre-operative chemotherapy. The postoperative chemotherapy regimen was decided according to the stage, risk stratification and metastatic status of the patient. RESULTS Data of 84 cases, including 40 (47.6%) males and 44 (52.4%) females was analyzed. The mean diagnostic age was 38.87 ± 28.66 months and 68 (81%) cases were less than five years of age. The commonest presenting features were abdominal mass in 75 (89.3%) cases. The right kidney was affected in 43 (51.2%) cases. Stage I disease was documented in 27 (32.1%) cases, stage II in 25 (29.8%), stage III in 13 (15.5%), and stage IV in 17 (20.2%) cases. In univariate analysis, advanced stage (P = < 0.001) and metastatic disease (P=< 0.001) adversely affected the treatment outcome. Multivariate analysis demonstrated that advanced stage WT was associated with the worst outcome (P= < 0.05). Four (4.8%) cases had treatment-related mortality (TRM). With a median follow-up time of 28.26 ± 23.03 months, OS and EFS were 66 (78.6%) and 63 (75.0%) respectively. DISCUSSION Delayed presentation with advanced-stage metastatic disease is quite common in the developing courtiers and is the major contributor to decreased EFS and OS. In the present study, 20.2% cases had metastatic disease, which is similar to reported from other developing countries. OS decreased from 92.6% in stage I to 47.1% in stage IV disease (P=< 0.001) and EFS decreased from 92.6% in stage I to 43.8% in stage IV disease (P=< 0.001). Very similar results are reported by a regional study [17]. Results in stage I and II disease are comparable to documented in the western world and inferior in advanced-stage disease. The strength of the present study is that multiple factors, affecting the treatment outcome of WT over almost seven years period were evaluated. CONCLUSIONS Stage of the disease is the most important prognostic factor. Delayed presentation with metastatic disease has a poor outcome.

Abstract
Introduction Wilms tumour (WT) is the most common childhood abdominal malignancy, with an average annual incidence of 1 in 10,000 children. The study published in 2002 reported lower survival rates of WT in Lithuania in comparison to the data of SIOP-9 study and the European Organization for Research and Treatment of Cancer (EORTC). We aimed to assess current diagnostic approach and treatment results of patients with WT treated at our institution and to compare the results with the previously published study. Materials and methods A retrospective single-centre study was performed. 48 patients with WT registered at the institutional data-base from 2000 to 2018 were enrolled. An estimated 5-year overall survival (OS5y) and 2-year event-free survival (EFS2y) by stage and risk groups was calculated using IBM SPSS. A comparative analysis of two time periods - 2000-2008 and 2009-2018 - was carried out. Results Forty-two (87.5%) patients presented with localised disease and 6 (12.5%) with primary metastatic disease. The majority of cases were of the intermediate-risk group (77%). The OS5yof all analysed children was 86.4%. The EFS2y was 88.9% in stage I, 91.7% in stage II, 83.3% in stage III, and 50% in stage IV. The EFS2y was 100% in the low-risk group, 86.5% in the intermediate-risk group, and 25% in the high-risk group. Improvement of outcomes was observed over the analysed period: OS5y changed from 81.0% in 2000-2008 to 92.6% in 2009-2018. Among 48 cases, ten patients showed recurrence: eight - early relapse and two - late relapse. Six patients died. Conclusions WT was diagnosed at early stages in most cases. The survival was better among the patients diagnosed in earlier stages and with favourable risk group. Better survival rates were observed in patients treated in 2009-2018 compared to the 2000-2008 period.

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
Children with cancer are at increased risk of life-threatening emergencies, either from the cancer itself or related to the cancer treatment. These conditions need to be assessed and treated as early as possible to minimize morbidity and mortality. Cardiothoracic emergencies encompass a variety of pathologies, including pericardial effusion and cardiac tamponade, massive hemoptysis, superior vena cava syndrome, pulmonary embolism, and pneumonia. Abdominal emergencies include bowel obstruction, intussusception, perforation, tumor rupture, intestinal graft-versus-host disease, acute pancreatitis, neutropenic colitis, and obstructive uropathy. Radiology plays a vital role in the diagnosis of these emergencies. We here review the clinical features and imaging in pediatric patients with oncologic emergencies, including a review of recently published studies. Key radiological images are presented to highlight the radiological approach to diagnosis. Pediatricians, pediatric surgeons, and pediatric radiologists need to work together to arrive at the correct diagnosis and to ensure prompt and appropriate treatment strategies.

Abstract
BACKGROUND/OBJECTIVE This study evaluates the outcome of Wilms tumor (WT) following introduction of multidisciplinary team management and patient treatment stratification by tumor histology in two referral centers in southeastern Nigeria. METHODS We analyzed histologically confirmed WT cases managed from January 2008 to June 2017. RESULTS There were 45 patients, peak age incidence of 2 to 5 years who presented after mean symptom duration of 4.9 months (range, 1-12 months), with mean tumor weight of 1040 g (range, 350-4200 g). Overall, 14 (31.1%) had unfavorable histology of WT. A total of 22 (48.9%) patients received preoperative chemotherapy, 43 (95.6%) received postoperative chemotherapy based on stage of disease and histopathology, but none received adequate radiotherapy. Of these, 19 (44.2%) patients complied with chemotherapy regimen, 15 (33.3%) were lost to follow-up and 12 (26.7%) cases relapsed. With 30 cases available for evaluation and mean follow-up duration of 23 months (range, 6-80 months), the overall 5-year survival is 53.3% (16 cases). Survival in children who complied with postoperative chemotherapy was 73.7%, and abandonment-sensitive survival was 35.6%. Persisting challenges were late presentation, poor compliance to treatment, and lack of radiotherapy treatment. CONCLUSION Multidisciplinary team management and chemotherapy based on tumor histology might have resulted in slight improvement of outcome since our last report. However, to ensure survival that may approach global benchmarks, there is need for public health measures to improve time to diagnosis, and improvement of facilities and healthcare funding to ensure compliance to all phases of standard therapy.

Clinical outcomes of children with Wilms tumor treated on a SIOP WT 2001 protocol in a tertiary care hospital in south India. J Pediatr Urol 2018; 14:547.e1-547.e7. [PMID: 30017606 DOI: 10.1016/j.jpurol.2018.05.020] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2017] [Accepted: 05/21/2018] [Indexed: 01/27/2023]
Abstract
INTRODUCTION Wilms tumor is the most common pediatric renal malignancy. While developed countries have had excellent survival, it remains poorer by comparison in developing countries. The aim was to analyze the clinical outcome of children with Wilms tumor managed in a developing country from 2004 to 2014 by the SIOP WT 2001 protocol. METHODS Fifty-nine children with Wilms tumor managed by a SIOP WT 2001 regimen from 2004 to 2014 were analyzed. RESULTS The median age at presentation was 36 months, and 59% were boys. The average size of the tumor at presentation was 523 mL. Inferior vena cava thrombus was present in 11, distant metastases in 18, and bilateral tumors in six. Preoperative chemotherapy was given to all children after a diagnostic core needle biopsy. Preoperative chemotherapy reduced the tumor size to a mean of 208 mL and resolved venacaval thrombus in eight. Fifty-five children underwent definitive surgery while two children died during preoperative chemotherapy and two remained inoperable. All surviving children received adjuvant chemotherapy with 17 receiving radiotherapy as well. The overall survival (OS) was 80% and the event-free survival (EFS) was 73% after a mean follow up of 42 months after completion of therapy. DISCUSSION The tumor volumes at presentation and the incidence of venous tumor thrombosis in our cohort were much higher than those reported from developed countries. The incidence of metastatic disease at diagnosis (30.5%) was significantly higher than the 10-12% reported in Western data, but similar to that reported from various developing countries (14.1-31%). The OS in our cohort was 80% and the EFS was 73% with there being no events after 28 months. Although the survival rate for localized disease is similar to that in developed countries, the OS for metastatic disease was significantly less (50% vs. 75%). We also found that using an upfront posterior flank core biopsy was safe and beneficial for differentiating Wilms tumor from other pediatric renal tumors that are less chemosensitive. CONCLUSION In a resource-restricted environment such as ours, the SIOP WT 2001 protocol has been found to show excellent results.

Abstract
INTRODUCTION Wilms' tumour is the most frequent renal tumour in children. Multi-modal treatment includes chemotherapy and surgery, with or without radiotherapy. The survival is excellent, with rates exceeding 90%. A review is presented on our experience over the last 15 years of treating Wilms' tumour in Hospital Niño Jesús, Madrid. PATIENTS AND METHODS A retrospective study was conducted on 40 consecutive paediatric patients diagnosed with nephroblastoma between 2002 and 2016 in the Hospital Niño Jesús in Madrid. The clinical characteristics, diagnostic methods, treatment, and follow-up were analysed. RESULTS Of the 40 patients, 23 were boys, with a median age at diagnosis of 2.5 years (range, 4 months-15 years). Three patients underwent initial nephrectomy, three received a fine needle aspiration biopsy, followed by chemotherapy, and 34 patients started pre-operative chemotherapy directly. The median follow-up of the patients was 6.75 years (range, 10 months - 13.92 years). Two patients died from disease progression. There were no treatment-related deaths. Overall survival and event-free survival at 5 years was 94.6±3.7% and 89.4±5%, respectively. CONCLUSION Wilms' tumour treatment is a success of modern medicine, currently achieving a survival rate of 95% in our series.

Abstract
BACKGROUND Outcome of children with Wilms tumor (WT) has improved remarkably because of the advancements in Pediatric Oncology. However, in most developing countries survival rates are still poor. There is a paucity of data regarding the clinical profile and outcome of children with WT in India. METHODS Children with WT who were treated at our center between 2005 and 2014 were retrospectively analyzed. RESULTS Over the 10-year study period, 108 children with WT were treated in our unit. The median age at presentation was 30 months (male:female ratio of 4:1). Abdominal mass was the most common presenting feature (91%). The majority of children had stage 2 (30%) or stage 3 (35%) disease. Fifty-nine children had large or bilateral tumors requiring preoperative chemotherapy. Of the total 108 children, 11 died during primary treatment and 14 relapsed after completion of treatment. The projected 5-year overall survival is 74%, whereas the event-free survival is 73%. CONCLUSIONS Children with WT in our setting present late with advanced disease and large tumors, which are technically difficult to deliver at surgery. With a multidisciplinary approach, reasonably good survival rates were achieved even in the resource-limited Indian scenario.
