Abstract
Surgical control has prognostic value in neuroblastoma (NB). Advanced NB is common at diagnosis in South Africa. We investigated the pre-surgery factors that influenced decisions to perform surgical resections. We included 204 patients with high-risk NB from a national retrospective study, who completed induction chemotherapy between 2000 and 2016.The median age was 32.4 months (IQR 15.1 - 53.5 months). Primary tumor resection was achieved in 76.9% of patients between 0-18 months of age, 51.8% between 18-60 months and 51.7% older than 60 months (p < 0.001). Only 43.2% of patients with distant metastatic disease had surgery done (p < 0.001). LDH was >750 U/L in 46.8% and ferritin >120 g/dL in 53.1% of those who had surgery (p = 0.005). The majority (80.4%), who had achieved post-induction metastatic complete remission (mCR), were operated, while 28.7% without mCR had surgery (p < 0.001). The long-term overall survival in patients with mCR and primary tumor resection was 36.5% compared to those with mCR without primary tumor resection (25.4%) and without mCR (≤3.0%)(p < 0.001). Age (p < 0.001), stage (p < 0.001), mCR (p < 0.001) and treatment setting (p < 0.001) were of prognostic significance. The tumor site and MYCN-amplification did not significantly predict resection rates. Post-induction mCR and stage were associated with surgical resection and five-year OS (p < 0.001) on multivariate analysis.Patients with high-risk NB who achieved mCR and had primary tumor resections are curable in limited resourced settings. Stage and post-induction mCR were significant variables that led to surgery. These variables should be included as indications in the management of metastatic NB in resource limited settings.

Treatment outcomes among high-risk neuroblastoma patients receiving non-immunotherapy regimen: Multicenter study on behalf of the Thai Pediatric Oncology Group. Pediatr Blood Cancer 2022; 69:e29757. [PMID: 35560972 DOI: 10.1002/pbc.29757] [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: 12/28/2021] [Revised: 04/12/2022] [Accepted: 04/18/2022] [Indexed: 11/07/2022]
Abstract
BACKGROUND Neuroblastoma is the most common extracranial malignant solid tumor during childhood. Despite intensified treatment, patients with high-risk neuroblastoma (HR-NBL) still carry a dismal prognosis. The Thai Pediatric Oncology Group (ThaiPOG) proposed the use of a multimodality treatment to improve outcomes of HR-NBL in non-immunotherapy settings. METHODS Patients with HR-NBL undergoing ThaiPOG protocols (ThaiPOG-NB-13HR or -18HR) between 2013 and 2019 were retrospectively reviewed. Patient demographic data, treatment modalities, outcomes, and prognostic factors were evaluated and analyzed. RESULTS A total of 183 patients with HR-NBL undergoing a topotecan containing induction regimen were enrolled in this study. During the consolidation phase (n = 169), 116 patients (68.6%) received conventional chemotherapy, while 53 patients (31.4%) underwent hematopoietic stem cell transplantation (HSCT). The 5-year overall survival (OS) and event-free survival (EFS) were 41.2% and 22.8%, respectively. Patients who underwent HSCT had more superior 5-year EFS (36%) than those who received chemotherapy (17.1%) (p = .041), although they both performed similarly in 5-year OS (48.7% vs. 39.8%, p = .17). The variation of survival outcomes was observed depending on the number of treatment modalities. HSCT combined with metaiodobenzylguanidine (MIBG) treatment and maintenance with 13-cis-retinoic acid (cis-RA) demonstrated a desirable 5-year OS and EFS of 65.6% and 58.3%, respectively. Poorly or undifferentiated tumor histology and cis-RA administration were independent factors associated with relapse and survival outcomes, respectively (p < .05). CONCLUSION A combination of HSCT and cis-RA successfully improved the outcomes of patients with HR-NBL in immunotherapy inaccessible settings.

Isolated central nervous system relapses in patients with high-risk neuroblastoma -clinical presentation and prognosis: experience of the Polish Paediatric Solid Tumours Study Group.

Abstract
Although isolated central nervous system (CNS) relapses are rare, they may become a serious clinical problem in intensively treated patients with high-risk neuroblastoma (NBL). The aim of this study is the presentation and assessment of the incidence and clinical course of isolated CNS relapses. Retrospective analysis involved 848 NBL patients treated from 2001 to 2019 at 8 centres of the Polish Paediatric Solid Tumours Study Group (PPSTSG). Group characteristics at diagnosis, treatment and patterns of relapse were analysed. Observation was completed in December 2020. We analysed 286 high risk patients, including 16 infants. Isolated CNS relapse, defined as the presence of a tumour in brain parenchyma or leptomeningeal involvement, was found in 13 patients (4.5%; 8.4% of all relapses), all of whom were stage 4 at diagnosis. Isolated CNS relapses seem to be more common in young patients with stage 4 MYCN amplified NBL, and in this group they may occur early during first line therapy. The only or the first symptom may be bleeding into the CNS, especially in younger children, even without a clear relapse picture on imaging, or the relapse may be clinically asymptomatic and found during routine screening. Although the incidence of isolated CNS relapses is not statistically significantly higher in patients after immunotherapy, their occurrence should be carefully monitored, especially in intensively treated infants, with potential disruption of the brain-blood barrier.

Abstract
PURPOSE Neuroblastoma management in children is multimodal and depends on multiple factors, including the possibility of complete surgical resection. Image-defined risk factors (IDRFs) are used to assess the feasibility of primary surgery. We studied the changes in IDRFs after neoadjuvant chemotherapy for thoracic neurogenic tumors. METHODS We performed a multicenter review of 27 patients presenting with unresectable thoracic neurogenic tumors. Patients received neoadjuvant chemotherapy, according to their risk group. IDRF at diagnosis and before surgery were retrospectively analyzed by a radiologist and a surgeon, blind to the initial assessment. Surgical and oncologic outcomes were reviewed. RESULTS None of the patients presented MYCN amplification, and 78 IDRFs were identified at diagnosis. Vascular IDRFs were the most frequent, with 28 vascular IDRFs detected in 18 patients, 22 of which disappeared after chemotherapy. Reductions of tumor volume were associated with a regression of IDRFs. Patients undergoing minimally invasive surgery had smaller tumor volumes than those undergoing open surgery, and no vascular IDRF. Two patients received two additional courses of chemotherapy to reduce tumor volume sufficiently for surgery. One patient with ganglioneuroblastoma underwent early surgery due to a lack of response to initial chemotherapy. CONCLUSION Tumor volume reduction with neoadjuvant chemotherapy eliminates most IDRF in thoracic neurogenic tumors. Vascular IDRF are rapidly resolved at this site, making surgical resection and minimally invasive surgery possible.

Abstract
Purpose: Evaluate the clinical efficacy and safety of minimally invasive surgery (MIS) and open surgery in the treatment of neuroblastoma (NB) in children by a meta-analysis. Materials and Methods: This is a meta-analysis. We searched for random or nonrandomized controlled study of MIS group and OPEN surgery group for the treatment of childhood NB included in PubMed, ClinicalTrials, EMBASE, and Cochrane library before January 31, 2020. Data extraction was performed in a standard format for the included studies, including tumor diameter, operation time, intraoperative bleeding, length of hospital stay (LOHS), complications, recurrence, and MYCN. Results: Seven retrospective studies were finally included, with a total of 571 children, including 162 in MIS group and 409 in the OPEN surgery group. Compared with the OPEN surgery group, the MIS group had reduced intraoperative bleeding (mean difference [MD] = -12.72, 95% CI: -24.84 to -0.61, P < .05), and reduced l LOHS (MD = -3.35, 95% CI: -5.55 to -1.15, P < .05) and decreased postoperative recurrence (MD = 0.20, 95% CI: 0.05-0.75, P < .05). The differences between the groups were statistically significant. There was no significant difference between groups in tumor diameter (MD = -18.84, 95% CI: -48.12 to 10.43, P > .05), operation time (MD = -21.7, 95% CI: -97.52 to 54.13, P > .05), and MYCN results (odds ratio = 2.27, 95% CI: 0.56-9.18, P > .05). Conclusions: Preliminary evidence indicates that the treatment of NB with MIS has the advantages of less intraoperative bleeding, shorter LOHS, and less postoperative recurrence compared with open surgery.

Abstract
Purpose: Neuroblastoma is the most common extracranial solid tumor in children, and most patients are at high risk when they are initially diagnosed. The roles of surgery and induction chemotherapy in patients with high-risk neuroblastoma have been a subject of much controversy and debate. The objective of the current study was to assess the roles of surgery in high-risk neuroblastoma. Method: The review protocol was prospectively registered (PROSPEROID: CRD42021253961). The PubMed, Embase, Cochrane, and CNKI databases were searched from inception to January 2020 with no restrictions on language or publication date. Clinical studies comparing the outcomes of different surgical ranges for the treatment of high-risk neuroblastoma were analyzed. The Mantel-Haenszel method and a random effects model was utilized to calculate the hazard ratio (95% CI). Results: Fourteen studies that assessed 1,915 subjects met the full inclusion criteria. Compared with the gross tumor resection (GTR) group, complete tumor resection (CTR) did not significantly improve the 5-year EFS [p = 1.0; HR = 0.95 (95% CI, 0.87-1.05); I 2 = 0%], and the 5-year OS [p = 0.76; HR = 1.08 (95% CI, 0.80-1.46); I 2 = 0%] of patients. GTR or CTR resection had significantly better 5-year OS [p = 0.45; HR = 0.56 (95% CI, 0.43-0.72); I 2 = 0%] and 5-year EFS [p = 0.15; HR = 0.80 (95% CI, 0.71-0.90); I 2 = 31%] than subtotal tumor resection (STR) or biopsy only; however, both CTR or GTR showed a trend for more intra and post-operative complications compared with the STR or biopsy only [p = 0.37; OR = 1.54 (95% CI, 1.08-2.20); I 2 = 0%]. The EFS of the patients who underwent GTR or CTR at the time of diagnosis and after induction chemotherapy were similar [p = 0.24; HR = 1.53 (95% CI, 0.84-2.77); I 2 = 29%]. Conclusion: For patients with high-risk neuroblastoma, complete tumor resection and gross tumor resection of the primary tumor were related to improved survival, with very limited effects on reducing intraoperative and postoperative complications. It is necessary to design strong chemotherapy regimens to improve the survival rate of advanced patients.

Abstract
Importance Irradiation treatment for pediatric patients with neuroblastoma represents a major challenge due to the pediatric dose limits for critical structures and the necessity of sufficient dose coverage of the clinical target volume for local control. Objective To investigate dosimetric differences between tomotherapy (TOMO) and volumetric‐modulated arc therapy (VMAT) as retroperitoneal radiotherapy for children with neuroblastoma. Methods Eight patients who received retroperitoneal radiotherapy for neuroblastoma were selected for comparison of TOMO and VMAT treatment plans. The Dmin, Dmax, Dmean, D95, D2, and D98 of planning target volume (PTV), conformity index (CI), heterogeneity index (HI), and organs at risk (OARs) parameters were compared. Delivery machine unit (MU) and image‐guide radiotherapy solution results were also compared. Results All patients received a cumulative dose of 19.5 Gy to the PTV. VMAT showed higher CI (0.93 ± 0.02), compared with TOMO (0.87 ± 0.03, P < 0.001). Notably, the average PTV HI was significantly better using TOMO (1.05 ± 0.01) than VMAT (1.08 ± 0.02, P = 0.003). Compared with VMAT, the Dmin, D95, and D98 all exhibited increases in TOMO; Dmax variation was less than 1% in TOMO. The D0.1cc for the spinal cord and D2cc for the small intestine were better in TOMO in terms of OARs. However, TOMO had more MUs and required a longer delivery time. Interpretation Both planning techniques are capable of producing high‐ quality treatment plans. TOMO is superior for PTV coverage, but inferior for CI. TOMO requires extra treatment time; its cost is greater than the cost of VMAT.

Abstract
PURPOSE A primary objective of the Children's Oncology Group (COG) ANBL0532 phase III study was to assess the effect of increasing local dose of radiation to a residual primary tumor on the cumulative incidence of local progression (CILP) in patients with high-risk neuroblastoma. PATIENTS AND METHODS Newly diagnosed patients with high-risk neuroblastoma were randomly assigned or assigned to receive single or tandem autologous stem-cell transplantation (SCT) after induction chemotherapy. Local control consisted of surgical resection during induction chemotherapy and radiotherapy after last SCT. Patients received 21.6 Gy to the preoperative primary tumor volume. For patients with incomplete surgical resection, an additional boost of 14.4 Gy was delivered to the gross residual tumor, for a total dose of 36 Gy. CILP (primary end point) and event-free (EFS) and overall survival (OS; secondary end points) were compared with the COG A3973 historical cohort, in which all patients received single SCT and 21.6 Gy without a boost. RESULTS For all patients in ANBL0532 receiving radiotherapy (n = 323), 5-year CILP, EFS, and OS rates were 11.2% ± 1.8%, 56.2% ± 3.4%, and 68.4% ± 3.2% compared with 7.1% ± 1.4% (P = .0590), 47.0% ± 3.5% (P = .0090), and 57.4% ± 3.5% (P = .0088) for all patients in A3973 receiving radiotherapy (n = 328), respectively. Five-year CILP, EFS, and OS rates for patients in A3973 with incomplete resection and radiotherapy (n = 47) were 10.6% ± 4.6%, 48.9% ± 10.1%, and 56.9% ± 10.0%, respectively. In comparison, 5-year CILP, EFS, and OS rates for patients in ANBL0532 who were randomly assigned or assigned to single SCT and received boost radiotherapy (n = 74) were 16.3% ± 4.3% (P = .4126), 50.9% ± 7.0% (P = .5084), and 68.1% ± 6.7% (P = .2835), respectively. CONCLUSION Boost radiotherapy to gross residual tumor present at the end of induction did not significantly improve 5-year CILP. These results highlight the need for new strategies to decrease the risk of locoregional failure.

Impact of extent of resection on survival in high-risk neuroblastoma: A systematic review and meta-analysis. J Pediatr Surg 2019; 54:1487-1494. [PMID: 30262202 DOI: 10.1016/j.jpedsurg.2018.08.046] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/09/2018] [Revised: 08/20/2018] [Accepted: 08/20/2018] [Indexed: 02/05/2023]
Abstract
BACKGROUND Despite the development of new treatment options, the prognosis of high-risk neuroblastoma patients is still poor. Many studies designed to elaborate the association between the extent of resection (EOR) and outcome have reported conflicting results. We performed a meta-analysis to assess whether greater EOR is associated with improved overall survival (OS) and event-free survival (EFS) in patients with high-risk neuroblastoma. METHODS Embase, PubMed, Cochrane library, and conference proceedings were searched between March 10 and October 1, 2017. Studies of pediatric patients with newly diagnosed high-risk neuroblastoma comparing various EOR and presenting objective overall or event-free survival data were included. Primary outcomes were relative risk (RR) for mortality at 3 and 5 years. Secondary outcomes were 3-year and 5-year EFS rates. RESULTS 19 retrospective studies including a total of 2358 cases were identified. Compared with subtotal resection (STR), patients who underwent gross total resection (GTR) had significantly decreased mortality at 3 years (RR, 0.69; 95% CI, 0.58-0.82; P < 0.001; I2 = 27%) and 5 years (RR, 0.70; 95% CI, 0.60-0.82; P < 0.001; I2 = 38%). A similar decrease was revealed in the 3-year risk for mortality for STR compared with biopsy (RR, 0.71; 95% CI, 0.53-0.95; P = 0.02; I2 = 0%). When comparing any resection with biopsy, resection group also showed a decreased risk for mortality at 3 years (RR, 0.66; 95% CI, 0.53-0.83; P < 0.001; I2 = 8%) and 5 years (RR, 0.67; 95% CI, 0.50-0.91; P = 0.009; I2 = 61%). With respect to the risk ratio for EFS, there were no significant differences in any comparisons. CONCLUSION This literature highlights the importance of "extent of resection" in treating high-risk neuroblastoma, and when feasible, the currently available evidences in favor of the use of GTR for high-risk neuroblastoma for reducing 3- and 5-year mortality. LEVEL OF EVIDENCE 3A.

Caval replacement strategy in pediatric retroperitoneal tumors encasing the vena cava: a single-center experience and review of literature. J Pediatr Surg 2019; 54:557-561. [PMID: 29980348 DOI: 10.1016/j.jpedsurg.2018.06.008] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/18/2018] [Revised: 06/03/2018] [Accepted: 06/04/2018] [Indexed: 12/12/2022]
Abstract
BACKGROUND Complete encasement of the inferior vena cava by retroperitoneal tumors is rare. Although replacement of the vena cava has been considered for various conditions in adults, it is rarely used in children except for challenging resections and as a last chance approach - often aiming more at debulking than cure. MATERIALS AND METHODS From January 2009 to February 2017, 4 patients (2 adrenal neuroblastomas, 1 renal cell carcinoma, 1 infantile fibrosarcoma) underwent elective en-bloc resection of tumor and of the infrahepatic portion of the inferior vena cava (IVC), with planned IVC prosthetic replacement. In three cases a portion of the left renal vein had to be resected as well, with the vein reanastomosed onto the prosthesis, and a concomitant auto-transplantation of the right kidney was associated in one neuroblastoma patient. RESULTS All patients had an uncomplicated postoperative course. In one patient, the prosthetic conduit is patent at long-term (43 months), while the middle portion of the prosthesis did eventually thrombose at mid-term after surgery in the three others - with no related symptoms. Interestingly, all renal venous reconstructions remain patent. Three patients (2 neuroblastomas and 1 infantile fibrosarcoma) are alive and disease-free at 43, 74 and 108 months after surgery, respectively. One patient with renal cell carcinoma died of recurrence of the disease 21 months after surgery. CONCLUSION Resection and reconstruction of the vena cava, including the renal vein portion, can be considered and planned electively in case of tumoral encasement. This strategy is associated with good tolerance of the operation, low morbidity and satisfactory long-term function, even in cases with progressive and/or secondary partial thrombosis. LEVEL OF EVIDENCE IV.

Clin Oncol (R Coll Radiol) 2018; 31:182-190.

Abstract
AIMS External beam radiotherapy is widely used in various ways in the management of neuroblastoma. Despite extensive clinical experience, the precise role of radiotherapy in neuroblastoma remains unclear. The purpose of this systematic review was to survey the published literature to identify, without bias, the evidence for the clinical effectiveness of external beam radiotherapy as part of the initial multimodality treatment of high-risk neuroblastoma. We considered four areas: treatment of the tumour bed and residual primary tumour, identification of any dose-response relationship, treatment of metastatic sites, identification of any technical advances that may be beneficial. We also aimed to define uncertainties, which may be clarified in future clinical trials. MATERIALS AND METHODS Bibliographic databases were searched for neuroblastoma and radiotherapy. Reviewers assessed 1283 papers for inclusion by title and abstract, with consensus achieved through discussion. Data extraction on 57 included papers was carried out by one reviewer and checked by another. Studies were assessed for their level of evidence and risk of bias, and a descriptive analysis of data was carried out. RESULTS Fifteen papers provided some evidence that radiotherapy to the tumour bed and residual tumour may possibly be of value. However, there is a significant risk of bias and no evidence that all subgroups will benefit. There is some suggestion from six papers that dose may be important, but no hard evidence. It remains unclear whether irradiation of metastatic sites is helpful. Technical advances may be of value in radiotherapy of high-risk neuroblastoma. CONCLUSIONS There are data that show that radiotherapy is of some efficacy in the management of high-risk neuroblastoma, but there is no level one evidence that shows that it is being used in the best possible way. Prospective randomised trials are necessary to provide more evidence to guide development of optimal radiotherapy treatment schedules.

Abstract
OBJECTIVE This study was to review the efficacy of surgical resections in different clinical situations for a better understanding of the meaning of surgery in the treatment of neuroblastoma (NB). DATA SOURCES The online database ScienceDirect (201-2018) was utilized. The search was conducted using the keywords "neuroblastoma," "neuroblastoma resection," "neuroblastoma surgery," and "high-risk neuroblastoma." STUDY SELECTION We retrospectively analyzed of patients who underwent surgical resections in different clinical situations. The article included findings from selected relevant randomized controlled trials, systematic reviews, and meta-analyses or good-quality observational studies. Abstracts only, letters, and editorial notes were excluded. Full-text articles and abstracts were extracted and reviewed to identify key articles discussing surgery management of NB, which were then selected for critical analysis. RESULTS A total of 7800 English language articles were found containing references to NB (201-2018). The 163 articles were searched which were related to the surgical treatment of NB (201-2018). Through the analysis of these important articles, we found that the treatments of NB at low- and intermediate-risk groups were basically the same. High-risk patients remained controversial. CONCLUSIONS NB prognosis varies tremendously based on the stage and biologic features of the tumor. After reviewing the relevant literature, patients with low-risk disease are often managed with surgical resection or observation alone with tumors likely to spontaneously regress that are not causing symptoms. Intermediate patients are treated with chemotherapy with the number of cycles depending on their response as well as surgical resection of the primary tumor. High-risk patients remain controversial. Multidisciplinary intensive treatment is essential, especially for patients who received subtotal tumor resection. Minimally invasive surgery for the treatment of NBs without image-defined risk factors in low- to high-risk patients is safe and feasible and does not compromise the treatment outcome. We conclude that ≥90% resection of the primary tumor is both feasible and safe in most patients with high-risk NB. New targeted therapies are crucial to improve survival.

Abstract
BACKGROUND Locoregional failure is common after subtotal resection in high-risk neuroblastoma. Although a dose of 21 Gy radiation therapy (RT) is standard for treatment of high-risk neuroblastoma after gross total resection, the dose needed for local control of patients with gross residual disease at the time of RT is unknown. We sought to evaluate local control after 21-36 Gy RT in patients with high-risk neuroblastoma undergoing subtotal resection. METHODS All patients with high-risk neuroblastoma who received RT to their primary site from 2000 to 2016 were reviewed. Of the 331 patients who received consolidative RT to their primary site, 19 (5.7%) underwent subtotal resection and were included in our analysis. Local failure (LF) was correlated with biologic prognostic factors and dose of RT. RESULTS Median follow-up among surviving patients was 6.0 years. Median RT dose was 25 Gy (range, 21 Gy-36 Gy). The 5-year cumulative incidence of LF among all patients was 17.2%. LF at 5 years was 30% in those who received <30 Gy versus 0% in those who received 30-36 Gy (P = 0.12). There was a trend towards improved local control in patients with tumor size ≤10 cm at diagnosis (P = 0.12). The 5-year event-free and overall survival were 44.9% and 68.7%, respectively. CONCLUSION After subtotal resection, patients who received less than 30 Gy had poor local control. Doses of 30-36 Gy are likely needed for optimal control of gross residual disease at the time of consolidative RT in high-risk neuroblastoma.

Abstract
Neuroblastoma is one of the most common solid tumors in children and has a diverse clinical behavior that largely depends on the tumor biology. Neuroblastoma exhibits unique features, such as early age of onset, high frequency of metastatic disease at diagnosis in patients over 1 year of age and the tendency for spontaneous regression of tumors in infants. The high-risk tumors frequently have amplification of the MYCN oncogene as well as segmental chromosome alterations with poor survival. Recent advanced genomic sequencing technology has revealed that mutation of ALK, which is present in ~10% of primary tumors, often causes familial neuroblastoma with germline mutation. However, the frequency of gene mutations is relatively small and other aberrations, such as epigenetic abnormalities, have also been proposed. The risk-stratified therapy was introduced by the Japan Neuroblastoma Study Group (JNBSG), which is now moving to the Neuroblastoma Committee of Japan Children's Cancer Group (JCCG). Several clinical studies have facilitated the reduction of therapy for children with low-risk neuroblastoma disease and the significant improvement of cure rates for patients with intermediate-risk as well as high-risk disease. Therapy for patients with high-risk disease includes intensive induction chemotherapy and myeloablative chemotherapy, followed by the treatment of minimal residual disease using differentiation therapy and immunotherapy. The JCCG aims for better cures and long-term quality of life for children with cancer by facilitating new approaches targeting novel driver proteins, genetic pathways and the tumor microenvironment.

Abstract
The current multidisciplinary treatment for patients with high-risk neuroblastoma (NB) is the common census. However, protocols and opinions are different in different regions and institutions. We aimed to assess the protocol formulated by Chinese Children's Cancer Group study in 2009, and the impact of surgery extent was highlightly evaluated. METHODS This study enrolled patients with high-risk neuroblastoma between 2009 and 2014 in Department of Pediatric Oncology of Tianjin Medical University Cancer Institute and Hospital. The clinical characteristics of patients were illustrated and surgery extent was evaluated by the impact on survival rate. RESULTS The 3-year overall survival (OS) and progression-free survival (PFS) were 56.2% and 50.5%, respectively. LDH (P<0.001), bone marrow metastasis at time of diagnosis (P=0.001), bone marrow negative after neoadjuvant chemotherapy (P<0.001), radiotherapy (P<0.001) were significant predictors of OS and PFS. And surgery extent had no impact on the enhancement of high-risk neuroblastoma patients in short time. CONCLUSIONS This study showed no substantial survival benefit in patients with high-risk NB undergoing gross total tumor resection. Multidisciplinary intensive treatment was essential, especially for patients received subtotal tumor resection. Longer term follow-up is needed to survey complications in surviving patients who received intensive chemotherapy and radiotherapy.

Abstract
BACKGROUND The aim of the present study was to compare the efficacy, complications and outcomes of the following two surgical strategies for delayed local treatment for International Neuroblastoma Staging System (INSS) 4 neuroblastoma (NB): complete resection (CR; period A); and gross total resection/subtotal resection (GTR/STR) with local irradiation (period B). METHODS We retrospectively analyzed 17 patients with INSS 4 NB who received delayed local treatment (period A, n = 11; period B, n = 6). RESULTS Eleven patients in period A received CR. Two patients underwent GTR and four patients underwent STR in period B. The amount of blood loss in period A was significantly greater than that in period B. Postoperative complications were observed in eight patients in period A (73%), but in only one patient in period B (17%; P < 0.01). Recurrence was observed in five patients in period A and in one patient in period B (45.4% vs 16.6%; P = n.s.). Distant metastasis at recurrence was observed in four patients in period A and in one patient in period B. CONCLUSIONS Gross total resection/subtotal resection with local irradiation may be a safe and effective delayed local treatment for INSS 4 NB.

Abstract
Purpose This analysis of patients in the Children's Oncology Group A3973 study evaluated the impact of extent of primary tumor resection on local progression and survival and assessed concordance between clinical and central imaging review-based assessments of resection extent. Patients and Methods The analytic cohort (n = 220) included patients who had both central surgery review and resection of the primary tumor site. For this analysis, resection categories of < 90% and ≥ 90% were used, with data on resection extent derived from operating surgeons' assessments (all patients), as well as blinded central imaging review of computed tomography scans for a subset of 84 patients; assessment results were compared for concordance. Treatment outcomes included event-free survival (EFS), overall survival (OS), and cumulative incidence of local progression (CILP). Results Surgeon-assessed extent of resection was ≥ 90% in 154 (70%) patients and < 90% in 66 (30%). Five-year EFS, OS, and CILP (± SE) were 43.5% ± 3.7%, 54.9% ± 3.7%, and 11.9% ± 2.2%, respectively. EFS was higher with ≥ 90% resection (45.9% ± 4.3%) than with < 90% resection (37.9% ± 7.2%; P = .04). Lower CILP ( P = .01) was associated with ≥ 90% resection (8.5% ± 2.3%) compared with < 90% resection (19.8% ± 5.0%). On multivariable analysis, ≥ 90% resection was associated with longer EFS after adjustment for MYCN amplification or diploidy but had no significant effect on OS. Concordance between surgeons' assessments of resection extent and central image-guided review was low, with agreement of 63% (< 90% v ≥ 90%; simple κ = -0.0301). Conclusion Despite discordance between clinical assessment of resection extent and assessment via central imaging review, a surgeon-assessed resection extent ≥ 90% was associated with significantly better EFS and lower CILP. Improving OS, however, remains a challenge in this disease. These findings support continued attempts at ≥ 90% resection of the primary tumor in high-risk neuroblastoma.

SPARC overexpression combined with radiation retards angiogenesis by suppressing VEGF-A via miR‑410 in human neuroblastoma cells. Int J Oncol 2016; 49:1394-406. [PMID: 27498840 PMCID: PMC5021251 DOI: 10.3892/ijo.2016.3646] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2016] [Accepted: 07/06/2016] [Indexed: 12/11/2022] Open
Abstract
Neuroblastoma (NB) is the most common extracranial solid tumor in children and despite aggressive therapy survival rates remain low. One of the contributing factors for low survival rates is aggressive tumor angiogenesis, which is known to increase due to radiation, one of the standard therapies for neuroblastoma. Therefore, targeting tumor angiogenesis can be a viable add-on therapy for the treatment of neuroblastomas. In the present study, we demonstrate that overexpression of secreted protein acidic and rich in cysteine (SPARC) suppresses radiation induced angiogenesis in SK-N-BE(2) and NB1691 neuroblastoma cells. We observed that overexpression of SPARC in SK-N-BE(2) and NB1691 cells reduced radiation induced angiogenesis in an in vivo mouse dorsal skin model and an ex vivo chicken CAM (chorioallantoic-membrane) model and also reduced tumor size in subcutaneous mouse tumor models of NB. We also observed that SPARC overexpression reduces VEGF-A expression, in SK-N-BE(2) and NB1691 NB cells via miR-410, a VEGF-A targeting microRNA. SPARC overexpression alone or in combination with miR-410 and radiation was shown to be effective at reducing angiogenesis. Moreover, addition of miR-410 inhibitors reversed SPARC mediated inhibition of VEGF-A in NB1691 cells but not in SK-N-BE(2) NB cells. In conclusion, the present study demonstrates that the over-expression of SPARC in combination with radiation reduced tumor angiogenesis by downregulating VEGF-A via miR-410.

[PMID: 27473818 DOI: 10.1016/j.ijrobp.2016.05.020] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/29/2016] [Revised: 04/27/2016] [Accepted: 05/19/2016] [Indexed: 11/30/2022]
Abstract
PURPOSE To evaluate local control after 21-Gy radiation therapy (RT) to the primary site in patients with high-risk neuroblastoma. METHODS AND MATERIALS After receiving dose-intensive chemotherapy and gross total resection (GTR), 246 patients (aged 1.2-17.9 years, median 4.0 years) with high-risk neuroblastoma underwent RT to the primary site at Memorial Sloan Kettering from 2000 to 2014. Radiation therapy consisted of 21 Gy in twice-daily fractions of 1.5 Gy each. Local failure (LF) was correlated with biologic prognostic factors and clinical findings at the time of diagnosis and start of RT. RESULTS Median follow-up of surviving patients was 6.4 years. Cumulative incidence of LF was 7.1% at 2 years after RT and 9.8% at 5 years after RT. The isolated LF rate was 3.0%. Eighty-six percent of all local failures were within the RT field. Local control was worse in patients who required more than 1 surgical resection to achieve GTR (22.4% vs 8.3%, P=.01). There was also a trend toward inferior local control with MYCN-amplified tumors or serum lactate dehydrogenase ≥1500 U/L (P=.09 and P=.06, respectively). CONCLUSION After intensive chemotherapy and maximal surgical debulking, hyperfractionated RT with 21 Gy in high-risk neuroblastoma results in excellent local control. Given the young patient age, concern for late effects, and local control >90%, dose reduction may be appropriate for patients without MYCN amplification who achieve GTR.
