Abstract
BACKGROUND Patient-specific 3D models of neuroblastoma and relevant anatomy are useful tools for surgical planning. However, these models do not represent the heterogenous biology of neuroblastoma. This heterogeneity is visualized with the ADC and 123I-MIGB-SPECT-CT imaging. Combining these multi-modal data into preoperative 3D heatmaps, may allow differentiation of the areas of vital and non-vital tumor tissue. We developed a workflow to create multi-modal preoperative 3D models for neuroblastoma surgery. METHODS We included 7 patients who underwent neuroblastoma surgery between 2022 and 2023. We developed 3D models based on the contrast enhanced T1-weighted MRI scans. Subsequently, we aligned the corresponding ADC and 123I-MIBG-SPECT-CT images using rigid transformation. We estimated registration precision using the Dice score and the target registration error (TRE). 3D heatmaps were computed based on ADC and 123I-MIBG uptake. RESULTS The registration algorithm had a median Dice score of 0.81 (0.75-0.90) for ADC and 0.77 (0.65-0.91) for 123I-MIBG-SPECT. For the ADC registration, the median TRE of renal vessels was 4.90 mm (0.86-10.18) and of the aorta 4.67 mm (1.59-12.20). For the 123I -MIBG-SPECT imaging the TRE of the renal vessels was 5.52 mm (1.71-10.97) and 5.28 mm (3.33-16.77) for the aorta. CONCLUSIONS We successfully developed a registration workflow to create multi-modal 3D models which allows the surgeon to visualize the tumor and its biological behavior in relation to the surrounding tissue. Future research will include linking of pathological results to imaging data, to validate these multi-modal 3D models. LEVEL OF EVIDENCE Level IV. TYPE OF STUDY Clinical Research.

Effects of barakol from Cassia siamea on neuroblastoma SH-SY5Y cell line: A potential combined therapy with doxorubicin. Heliyon 2024; 10:e24694.

Abstract
Management of neuroblastoma is challenging because of poor response to drugs, chemotherapy resistance, high relapse, and treatment failures. Doxorubicin is a potent anticancer drug commonly used for neuroblastoma treatment. However, doxorubicin induces considerable toxicities, particularly those caused by oxidative-related damage. To minimize drug-induced adverse effects, the combined use of anticancer drugs with natural-derived compounds possessing antioxidant properties has become an interesting treatment strategy. Barakol is a major compound found in Cassia siamea, an edible plant with antioxidant and anticancer properties. Therefore, barakol could potentially be used in combination with doxorubicin to synergize the anticancer effect, while minimizing the oxidative-related toxicities. Herein, the potential of barakol (0.0043-43.0 μM) to synergize the anticancer effect of low-dose doxorubicin (0.5 and 1.0 μM) was investigated. Results indicated that barakol could enhance the cytotoxic effect of low-dose doxorubicin by affecting the cell viability of the treated cells. Furthermore, the co-treatment with barakol and low-dose doxorubicin decreased the levels of intracellular ROS when compared with the control. Moreover, the antimetastatic effect of the barakol itself was studied through its ability to inhibit metalloproteinase-3 (MMP-3) activity and prevent cell migration. Results revealed that the barakol inhibited MMP-3 activity and prevented cell migration in time- and dose-dependent manners. Additionally, barakol was a non-cytotoxic agent against the normal tested cell line (MRC-5), which suggested its selectivity and safety. Taken together, barakol could be a promising compound to be further developed for combination treatment with low-dose doxorubicin to improve therapeutic effectiveness but decrease drug-induced toxicities. The inhibitory effects of barakol on MMP-3 activity and cancer cell migration also supported its potential to be developed as an antimetastatic agent.

Abstract
Neuroblastoma is the most common extracranial solid malignancy in children. This study was undertaken to determine the long-term survival of neuroblastoma patients receiving conventional therapeutics (surgery, chemotherapy, and radiotherapy). The neuroblastoma patients examined were registered in the Surveillance, Epidemiology and End Results (SEER) database (1975-2016). Using propensity score matching analysis, the patients were paired by record depending on whether they received surgery, chemotherapy, or radiotherapy. Univariate and multivariate analyses of the disease-specific survival of the paired patients were performed by the log-rank test and Cox regression assay. A total of 4568 neuroblastoma patients were included in this study. During 1975-2016, the proportion of histopathological grade III/IV cases receiving surgery gradually increased, while the number of patients with tumors of grade I to IV undergoing chemotherapy or radiotherapy was stable or even decreased. After propensity score analysis, for Grade I + II and Grade III tumors, surgery obviously improved the disease-specific survival of patients, while chemotherapy was unfavorable for patient prognosis, and radiotherapy exerted no obvious effect on the patients. However, no matter what treatment was chosen, the patients with advanced-histopathological-grade tumors had a poor prognosis. Meanwhile, for all histopathological grades, the patients receiving surgery and subsequent chemotherapy or radiotherapy suffered from worsen disease-specific survival than those simply undergoing surgery. Fortunately, the negative effects of surgery, chemotherapy, or radiotherapy improved gradually over time. Surgery improved the long-term survival of the neuroblastoma patients, while chemotherapy and radiotherapy exerted an unfavorable impact on patient outcome. These results provide an important reference for the clinical treatment of neuroblastoma.

Abstract
Neuroblastoma is the most common solid tumor in children. New treatment approaches are needed because of the harmful side effects and costs of the methods used in the treatment of neuroblastoma. Medicinal and aromatic plants are important for new treatment approaches due to their minimal side effects and economic advantages. Therefore, the present study was carried out to examine the cytotoxic effect of Chaerophyllum macropodum extract on human neuroblastoma (SH-SY5Y) and fibroblast (HDFa) cell lines. 3-[4,5-dimethylthiazole-2-yl]-2,5-diphenyltetrazolium bromide (MTT) and lactate dehydrogenase release (LDH) assays were used to determine the cytotoxic effect of C. macropodum. The extracts were analyzed for their phenolic content by HPLC-PDA. Major components were determined as 63.600% o-coumaric acid, 15.606% catechine hydrate, 8.713% rosmarinic acid, 4.376% clorogenic acid, and 3.972% salicylic acid. The obtained results from cytotoxicity testing revealed that C. macropodum exerted a significant cytotoxic effect on human neuroblastoma cells at all tested concentrations (p < 0.05). But it did not lead to any cytotoxic potential on human fibroblasts. As a result, the obtained data clearly revealed C. macropodum exerted a selective cytotoxic action on neuroblastoma cells for the first time.

Abstract
Ganglioneuroblastoma is a rare peripheral neuroblastic tumor located anywhere in the sympathetic nervous system but rarely in the retropharyngeal space. Diagnosis can often be difficult based on imaging alone. We describe one case of a child presenting with snoring. The lesion was located in the rare retropharyngeal space, and its histology finally revealed ganglioneuroblastoma. Therefore, clinicians should be aware of pediatric patients with respiratory symptoms indicating cervical ganglioneuroblastoma. To make a definite diagnosis as soon as possible, a core needle biopsy or even immunohistochemistry may need to be performed before surgery.

Abstract
Neuroblastoma (NB) is one of the most frequently occurring neurogenic extracranial solid cancers in childhood and infancy. Over the years, many pieces of evidence suggested that NB development is controlled by gene expression dysregulation. These unleashed programs that outline NB cancer cells make them highly dependent on specific tuning of gene expression, which can act co-operatively to define the differentiation state, cell identity, and specialized functions. The peculiar regulation is mainly caused by genetic and epigenetic alterations, resulting in the dependency on a small set of key master transcriptional regulators as the convergence point of multiple signalling pathways. In this review, we provide a comprehensive blueprint of transcriptional regulation bearing NB initiation and progression, unveiling the complexity of novel oncogenic and tumour suppressive regulatory networks of this pathology. Furthermore, we underline the significance of multi-target therapies against these hallmarks, showing how novel approaches, together with chemotherapy, surgery, or radiotherapy, can have substantial antineoplastic effects, disrupting a wide variety of tumorigenic pathways through combinations of different treatments.

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
Neuroblastoma (NB) is a common solid extracranial tumor developing in pediatric populations. NB can spontaneously regress or grow and metastasize displaying resistance to therapy. This tumor is derived from primitive cells, mainly those of the neural crest, in the sympathetic nervous system and usually develops in the adrenal medulla and paraspinal ganglia. Our understanding of the molecular characteristics of human NBs continues to advance documenting abnormalities at the genome, epigenome, and transcriptome levels. The high-risk tumors have MYCN oncogene amplification, and the MYCN transcriptional regulator encoded by the MYCN oncogene is highly expressed in the neural crest. Studies on the biology of NB has enabled a more precise risk stratification strategy and a concomitant reduction in the required treatment in an expanding number of cases worldwide. However, newer treatment strategies are mandated to improve outcomes in pediatric patients who are at high-risk and display relapse. To improve outcomes and survival rates in such high-risk patients, it is necessary to use a multicomponent therapeutic approach. Accuracy in clinical staging of the disease and assessment of the associated risks based on biological, clinical, surgical, and pathological criteria are of paramount importance for prognosis and to effectively plan therapeutic approaches. This review discusses the staging of NB and the biological and genetic features of the disease and several current therapies including targeted delivery of chemotherapy, novel radiation therapy, and immunotherapy for NB.

Abstract
BACKGROUND High agglomeration of myeloid-derived suppressor cells (MDSCs) in neuroblastoma (NB) impeded therapeutic effects. This study aimed to investigate the role and mechanism of targeted inhibition of MDSCs by low-dose doxorubicin (DOX) to enhance immune efficacy in NB. METHODS Bagg albino (BALB/c) mice were used as tumor-bearing mouse models by injecting Neuro-2a cells, and MDSCs were eliminated by DOX or dopamine (DA) administration. Tumor-bearing mice were randomly divided into 2.5 mg/kg DOX, 5.0 mg/kg DOX, 50.0 mg/kg DA, and control groups (n = 20). The optimal drug and its concentration for MDSC inhibition were selected according to tumor inhibition. NB antigen-specific cytotoxic T cells (CTLs) were prepared. Tumor-bearing mice were randomly divided into DOX, CTL, anti-ganglioside (GD2), DOX+CTL, DOX+anti-GD2, and control groups. Following low-dose DOX administration, immunotherapy was applied. The levels of human leukocyte antigen (HLA)-I, CD8, interleukin (IL)-2 and interferon (IFN)-γ in peripheral blood, CTLs, T-helper 1 (Thl)/Th2 cytokines, perforin, granzyme and tumor growth were compared among the groups. The Wilcoxon two-sample test and repeated-measures analysis of variance were used to analyze results. RESULTS The slowest tumor growth (F = 6.095, P = 0.018) and strongest MDSC inhibition (F = 14.632, P = 0.001) were observed in 2.5 mg/kg DOX group. Proliferation of T cells was increased (F = 448.721, P < 0.001) and then decreased (F = 2.047, P = 0.186). After low-dose DOX administration, HLA-I (F = 222.489), CD8 (F = 271.686), Thl/Th2 cytokines, CD4+ and CD8+ lymphocytes, granzyme (F = 2376.475) and perforin (F = 488.531) in tumor, IL-2 (F = 62.951) and IFN-γ (F = 240.709) in peripheral blood of each immunotherapy group were all higher compared with the control group (all of P values < 0.05). The most significant increases in the aforementioned indexes and the most notable tumor growth inhibition were observed in DOX+anti-GD2 and DOX+CTL groups. CONCLUSIONS Low-dose DOX can be used as a potent immunomodulatory agent that selectively impairs MDSC-induced immunosuppression, thereby fostering immune efficacy in NB.

Abstract
INTRODUCTION CO2 pneumoperitoneum can influence the biological behavior of neuroblastoma (NB). Angiogenesis and genetic features are responsible for malignant phenotype of this tumor. We examined the CO2 effects on N-Myc, vascular endothelial growth factor (VEGF), and matrix metalloproteinase-2 (MMP-2) expression as critical biomarkers of tumor invasiveness, in NB cells without N-Myc amplification. MATERIALS AND METHODS SH-SY5Y cells were exposed to CO2 (100%) at 15 mm Hg pressure for 4 hours and then moved to normal condition for 24 hours. Control cells were incubated with 5% CO2 for the same time. In control and CO2-exposed cells, the messenger ribonucleic acid (mRNA) levels of hypoxia-inducible factor (HIF)-1α, HIF-2α, VEGF-A, and MMP-2 were quantified by real-time polymerase chain reaction. N-Myc expression was evaluated by Western blot analysis. RESULTS The exposure to 15 mm Hg CO2 (100%) for 4 hours induced an increase in HIF-1α, but not in HIF-2α, mRNA levels. No differences were observed in N-Myc expression between exposed and control cells at each incubation time. Similarly, no significant differences were found for VEGF-A and MMP-2 transcript levels. In CO2 exposed cells, we observed only a slight increase in both VEGF-A and MMP-2 mRNA levels after 4 and 24 hours in comparison to controls. CONCLUSION In our study, the hypoxic environment induced by CO2 exposure does not affect the expression of critical biomarkers of NB aggressiveness, such as N-Myc, VEGF, and MMP-2, in human SH-SY5Y NB cells without N-Myc amplification. These data suggest that CO2 pneumoperitoneum might not adversely impact NB cell invasiveness; however, it is necessary to evaluate these effects in others in vitro and in vivo models.

Abstract
Retroperitoneal neuroblastoma is a rare subtype of neuroblastoma and the role of age in its clinical prognosis is still unknown.To describe the age distribution and investigate the association between age and survival outcomes in patients diagnosed with retroperitoneal neuroblastoma.We retrospectively analyzed patients registered for retroperitoneal neuroblastoma in the Surveillance, Epidemiology, and End Results (SEER) national database from 1973 to 2015. Age distribution was described and Cox proportional hazard regression was used to evaluate the measured effect of age on overall survival and disease-specific survival.A total of 399 retroperitoneal neuroblastoma patients with a median follow-up of 53.0 (interquartile range 17.0-133.5) months were included. We found a unimodal distribution of age with a median age of diagnosis to be 1.0 (interquartile range 0.0-4.0) years. Univariate analysis suggested that transformed age was associated with an increased risk of total death and disease-specific death (OR = 4.2, 95% CI 3.0-5.9; OR = 4.7, 95% CI 3.2-6.8). Adjusted smoothed plots showed a nonlinear correlation between age and disease-specific death. The risk of disease-specific death did not increase sharply as the age increased until reaching the inflection point (age < 3 years, OR = 0.4, 95% CI 0.2-1.0; age ≥ 3 years, OR = 1.2, 95% CI 0.9-1.5). There was, however, a linear relationship between age and total deaths (OR = 1.0, 95% CI 0.7-1.2). Adjusted multivariate Cox regression analysis showed that ages ≥ 3 years were associated with a significant increased risks of disease-specific death and total death (OR = 2.5, 95% CI 1.7-3.8; OR = 2.3, 95% CI 1.6-3.3, respectively).There was a unimodal age distribution of retroperitoneal neuroblastoma usually presented in infants or younger child. Older age was associated with a lower chance of overall survival and the risk of disease-specific death increased sharply after 3 years of age.

Abstract
Nanotechnology is an emerged field to develop the plant mediated metal based nanodrugs by green method. In this current study, the zinc oxide metal based nanoparticles were developed using (Clausena lansium (Lour.) Skeels) Peel aqueous extracts and zinc nitrate. The C.L extract zinc nanoparticleswere indicated by the sharp peak seen at 350 nm utilizing the Ultraviolet-Visible spectroscopy (UV-Vis). The high peaks indicate the presence of phytochemicals and its functional groups in ZnONPs were studied by the Fourier Transform Infrared Spectroscopy (FT-IR). The X-Ray Diffraction analysis (XRD) explores the pattern and structure of ZnONPs as spherical and base-centered monoclinic crystalline shapes. The C.L extract with Zn nanoparticles were spherical in nature and the size of the synthesized particles were about 28.42 nm respectively. The autophagy (Beclin-1, LC3-I, LC3-II and ATG4B) and apoptotic (Bax, Bcl-2 and Caspase-3) proteins were regulated by the treatment with ZnONPs in SH-SY5Y neuroblastoma cells. The DNA loss or damage was occurred in the ZnONPs treatment and it was performed using Comet assay. The ZnONPs treatment generates the ROS in the cells and decreased its stability and viability. Addition of NAC prevents ROS in the cultured SH-SY5Y cells and prevents the cells from the apoptosis. We concluded that the ZnONPs potentially kills the neuroblastoma cells by producing the intracellular ROS.

World J Clin Cases 2019; 7:1499-1507. [PMID: 31363479 PMCID: PMC6656671 DOI: 10.12998/wjcc.v7.i12.1499] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/15/2019] [Revised: 04/29/2019] [Accepted: 05/11/2019] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Neuroblastoma (NB) is the most common extracranial solid tumor in children, with an incidence of approximately 1/10000. Surgical resection is an effective treatment for children with NB. Robot-assisted laparoscopic surgery is a new method and is superior to conventional laparoscopic surgery, since it has been preliminarily applied in clinical practice with a significant curative effect. This paper discusses significance and feasibility of complete resection of stage IV NB using robot-assisted laparoscopic surgery, while comparing its safety and effectiveness with conventional laparoscopic surgery.
CASE SUMMARY In June 2018, a girl with stage IV retroperitoneal NB, aged 3 years and 5 mo, was admitted. Her weight was 15 kg, and her height was 100 cm. Robot-assisted, five-port laparoscopic resection of NB was performed. Starting from the middle point between the navel and the anterior superior iliac spine to the left lower abdomen, the pneumoperitoneum and observation hole (10 mm) were established using the Hasson technique. Operation arm #1 was located between the left anterior axillary line, the navel, and the costal margin (8 mm); operation arm #2 was located at the intersection of the right anterior axillary line and Pfannenstiel line (8 mm); one auxiliary hole was located between arm #2 (on the Pfannenstiel line) and the observation hole (12 mm); and another auxiliary hole (5 mm) was located slightly below the left side of the xiphoid. Along the right line of Toldt and the hepatic flexure of the transverse colon, the colon was turned to the left and below with a hook electrode. Through Kocher's incision, the duodenum and the pancreatic head were turned to the left to expose the inferior vena cava and the abdominal aorta. The vein was separated along the right external iliac, and the inferior vena cava was then lifted to expose the right renal vein from the bottom to the top. The tumor was transected horizontally below the renal vein, and it was first cut into pieces and then resected. The right renal artery and the left renal vein were also exposed, and the retrohepatic inferior vena cava was isolated. The tumor was resected along the surface of the psoas muscle, the back of the inferior vena cava, and the right side of the abdominal aorta. Finally, the lymph node metas-tases in front of the abdominal aorta and left renal vein were completely removed. The specimens were loaded into a disposable specimen retrieval bag and removed from the enlarged auxiliary hole. T-tube drainage was placed and brought out through a hole in the right lower quadrant of the abdomen. The operative time was 389 min, the time of pneumoperitoneum was 360 min, the intraoperative blood loss was approximately 200 mL, and the postoperative recovery was smooth. There were no complications, such as lymphatic fistula, diarrhea, bleeding, and paralytic ileus. Two months after discharge, there were no other complications. The literature on the application of robot-assisted laparoscopic surgery in the treatment of NB in children was reviewed
CONCLUSION The robot has the advantages of a three-dimensional view and flexible operation, and it can operate finely along blood vessels. The successful experience of this case confirmed that robot-assisted laparoscopic surgery can skeletonize the abdominal blood vessels in the tumor and cut the tumor into pieces, indicating that robot-assisted laparoscopic surgery is feasible.

Abstract
BACKGROUND The expression of β-catenin and paired-like homeobox 2B (PHOX2B) expression were assessed in Neuroblastoma (NB) patients as a diagnostic, prognostic and/or predictive markers. METHODS Bone marrow (BM) samples of 52 NB patients were assessed for the expression of β-catenin by immunohistochemistry (IHC), and PHOX2B by real time PCR (RT-PCR), compared to 12 healthy normal controls (NC). The data were correlated to the clinic-pathological features of the patients, response to treatment and disease relapse. RESULTS β-catenin was expressed in 40 (76.92%) patients (P < .001). While PHOX2B was expressed in 32/52 (61.5%) patients, with a fold change of 0.29 (0.01-40.0, P = .096). β-catenin expression associated significantly with advanced tumor stage, high risk, positive results by MIBG and bone scan (P = .002, P < .001, P = .006, P = .013; respectively). Also it associated significantly with synaptophysin expression in the BM biopsy (P < .001), with a significant concordance (K = 0.519, P < .001). The expression of β-catenin associated significantly with PHOX2B gene expression [28/32 (87.5%), P = .04], and its fold change (P = .027), with a significant measure of agreement (K = 0.297, P = .022). The fold change of PHOX2B gene expression associated significantly with the high risk of the patients (P = .04). Poor response to treatment associated significantly with the expression of neuron specific enolase (NSE), β-catenin and PHOX2B in NB patients (P = .021, P = .019 and P = .040; respectively). The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of synaptophysin for the diagnosis of BM metastasis in NB patients were (69%, 65.2%, 71.4%, 62.5%; respectively, P = .024). While with β-catenin (93.1%, 43.5%, 67.5%, 83.3%; respectively, P = .003), and PHOX2B expression (65.5%, 34.5%, 59.4%, 50%; respectively, P = .574). CONCLUSION β-Catenin could be used as a sensitive and reliable marker for detection of BM metastasis and also a good predictor for resistance to treatment in NB patients. While, PHOX2B gene expression in BM aspirate could be a marker for high risk patients and poor response to treatment.

Abstract
Neuroblastoma is one of the children's malignant tumors with poor prognosis, as well as high recurrence and metastasis rates after surgical removal and chemotherapy. γδ T-cell based immunotherapy receives increasing attention thanks to the strong cytolytic activity to tumor cells. Our previous data revealed a significant increase in circulating γδ T-cell frequency in NB patients. In the present study, we found that beside a reduction of IFN-γ in serum of NB patients, DNAM-1 expression decreased in both circulating and PAM-expanded NB γδ T cells. Upon PAM stimulation, NB γδ T cells showed a reduced level of cell proliferation. In addition, the cytolytic activity of NB γδ T cells to NB cell lines was proved to be attenuated in a co-culture system. The fact that DNAM-1 neutralizing antibody abolished the tumor cell killing accentuates the indispensable role of DNAM-1 molecule in γδ T-cell cytolytic function.
