ABSTRACT

OBJECTIVE@#The coronavirus disease 2019 (COVID-19) pandemic has had a serious impact on health all over the world. Cancer patient, whose immunity is often compromised, faces a huge challenge. Currently, some COVID-19 vaccines are being developed and applied on general population; however, whether cancer patients should take COVID-19 vaccine remains unknown. Our study aimed to explore the knowledge, attitude, acceptance, and predictors of intention to receive the COVID-19 vaccine among cancer patients in Eastern China.@*METHODS@#A cross-sectional study was conducted in Eastern China from June 17th to September 3rd, 2021. Patients were selected using a convenience sampling method. A self-report questionnaire was developed to assess knowledge about the COVID-19 vaccine, attitude towards the vaccine and acceptance of the vaccine; following a review of similar studies previously published in the scientific literature, multivariate logistic regression analysis was used to determine the predictors associated with COVID-19 vaccine acceptance.@*RESULTS@#A total of 2158 cancer patients were enrolled in this study. The rate of vaccine hesitancy was 24.05% (519/2158); further, among the participants of vaccine acceptance, 767 had taken COVID-19 vaccine (35.54%), and 872 were willing to get vaccinated (40.01%). A total of 24 variables including demographic characteristics, clinical status of cancer, impact of COVID-19 pandemic on study participants, patients' knowledge about the COVID-19 vaccine, and attitude towards the vaccine, had significant differences between the "vaccine hesitancy" population and "vaccine acceptance" population. Multivariate logistic regression analysis indicated that parameters including alcohol consumption (odds ratio [OR] = 1.849; 95% confidence interval [CI]: 1.375-2.488; P-reference [P-Ref] < 0.001 vs non-drinkers), income impacted by COVID-19 pandemic (OR = 1.930, 2.037 and 2.688 for mild, moderate, and severe impact, respectively; all P-Ref < 0.01 vs no impact), knowledge of how the vaccine was developed (OR = 1.616; 95% CI: 1.126-2.318; P-Ref = 0.009 vs unknown), believing in the safety of the vaccine (OR = 1.502; 95% CI: 1.024-2.203; P-Ref = 0.038 vs denying the safety of vaccine), willingness to pay for the vaccine (OR = 3.042; 95% CI: 2.376-3.894; P-Ref < 0.001 vs unwilling), and willingness to recommend families and friends to get vaccinated (OR = 2.744; 95% CI: 1.759-4.280; P-Ref < 0.001 vs do not recommend) were contributors to vaccine acceptance. While such as being retired (OR = 0.586; 95% CI: 0.438-0.784; P-Ref < 0.001 vs unemployed), undergoing multiple therapies of cancer (OR = 0.408; 95% CI: 0.221-0.753; P-Ref = 0.004 vs no ongoing treatment), and worrying that the vaccine might deteriorate the prognosis of cancer (OR = 0.393; 95% CI: 0.307-0.504; P-Ref < 0.001 vs might not) were contributors to vaccine hesitancy.@*CONCLUSION@#This study provided preliminary estimates of the rates of vaccine acceptance and vaccine hesitancy among cancer patients in Eastern China. The intention to receive the COVID-19 vaccine was impacted by factors such as patient occupation, alcohol consumption, and some parts of knowledge about and attitude towards COVID-19 vaccine. It is recommended to develop individualized vaccination plans that meet the healthcare needs of cancer patients.

ABSTRACT

BACKGROUND@#With current chemotherapy treatment, >90% of survival has been obtained for Burkitt lymphoma (BL). In this study, the demographic characteristics and treatment outcomes are presented for 78 children in China with central nervous system-positive (CNS+) BL.@*METHODS@#This retrospective study consecutively enrolled 78 CNS+ BL patients in Beijing Children's Hospital (BCH) from 2007 to 2019 who received the BCH B-cell non-Hodgkin's lymphoma regimen (modified by French-American-British mature lymphoma B-cell 96 [FAB/LMB96] C1 arm ± rituximab). Clinical characteristics, methods of disease detection in the CNS, and outcomes were evaluated. Univariate and multivariate analyses were used to assess prognostic factors.@*RESULTS@#The median age of 65 boys and 13 girls at the time of diagnosis was 5.7 years (ranging from 1 to 14 years). Patients were followed up for a median time of 34 months (ranging from 1 to 72 months). Bone marrow invasion was found in 38 (48.7%) patients. There were 48 (61.5%), 44 (56.4%), and 25 (32%) patients with cranial nerve palsy, intracerebral mass (ICM), and para-meningeal extension, respectively. Abnormal cerebrospinal fluid (CSF) morphology and CSF immunophenotype appeared in 15 (19.2%) and 15 (19.2%) patients, respectively. There were 69 (88.5%) patients treated with chemotherapy combined with rituximab, and nine patients were treated solely with chemotherapy. Finally, five patients died of treatment-related infection, recurrence occurred for 13, and one developed a second tumor. The 3-year overall survival and event-free survival rates were 78.9% ± 4.7% and 71.4% ± 6.0%, respectively. Treatment with chemotherapy only, ICM positivity, and >4 organs involved at diagnosis were independent risk factors.@*CONCLUSIONS@#Rituximab combined with a modified LMB96 regimen has greatly increased the efficacy of treatment for Chinese children with CNS+ BL, and with the continuous collection of outcome data, treatment-related complications are decreasing. For further verification, a large sample multicentre randomized controlled study should be performed to explore a treatment scheme for Chinese children with even greater efficacy.

ABSTRACT

Objective:To examine the association of carotid plaque with variants in genes involved in inflammation and endothelial function.Methods:This was a multi-center, cross sectional survey in southwestern China. The residents aged ≥40 years and lived in the community for more than six months volunteered to participate in face-to-face survey in eight communities. A total of 2 377 subjects with high stroke risk were enrolled. Carotid plaque and plaque phenotype were assessed by carotid ultrasound. Genotypes of 19 variants in 10 genes related to inflammation and endothelial function were examined. Gene-gene interaction was analyzed by generalized multifactor dimensionality reduction (GMDR).Results:Carotid plaques were found in 852 (35.8%) subjects, of whom 454 (53.3%) had stable plaques, 398 (46.7%) had vulnerable plaques. PPARA rs4253655 ( OR=1.01, 95% CI 1.03-1.82), HABP2rs7923349 ( OR=1.18, 95% CI 1.06-3.11) and IL1A rs1609682 ( OR=1.09, 95% CI1.03-2.87) were associated with the carotid plaque presence, and NOS2Ars2297518 ( OR=1.05, 95% CI 1.02-2.64) and PPARArs4253655 ( OR=1.00, 95% CI 1.01-1.74) were associated with vulnerable plaque in univariate analysis. GMDR analysis showed that there was a significant gene-gene interaction among HABP2rs7923349, ITGA2rs1991013, IL1Ars1609682 and NOS2Ars8081248, and the high-risk interactive genotype among the four variants was independently associated with a higher risk for carotid vulnerable plaque after adjusting the covariates ( OR=2.81, 95% CI 1.32-7.49, P=0.005). Conclusions:Prevalence of carotid plaque was very high in the high risk stroke population in southwestern China. Variants in genes involved in endothelial function and inflammation were associated with the carotid plaque. The high-risk interactive genotype among HABP2rs7923349, ITGA2rs1991013, IL1Ars1609682 and NOS2Ars8081248 was independently associated with a higher risk for vulnerable plaque.

The levels of P and E 2/T in HC group were lower than those in pGA and AG group [(0.24±0.10) ng/ml, (0.27±0.11)ng/ml, (0.30±0.15) ng/ml; F=5.124, P<0.05] and [(0.006 6±0.002 2) ng/ml, (0.007 6±0.003 2) ng/ml, (0.008 0±0.003 8) ng/ml; F=3.787, P<0.05), while those in IG and CG group were lower than those in AG group [(0.25±0.09) ng/ml, (0.26±0.08) ng/ml, (0.30±0.15) ng/ml; F=5.124, P<0.05]; ② Spearman correlation analysis showed that E 2 level in pGA group was positively correlated with T and CysC( r=0.310, P<0.01; r=0.164, P=0.008), negatively correlated with MO ( r=-0.133, P=0.030), P level was positively correlated with MO ( r=0.139, P=0.023), T level was positively correlated with Crea and CysC ( r=0.179, P=0.003; r=0.162, P=0.008), negatively correlated with WBC, GR and MO ( r=-0.140, P=0.022; r=-0.173, P=0.005; r=-0.149, P=0.015), E 2/T was positively correlated with apob1 and Glu ( r=0.131, P=0.032; r=0.140, P=0.023). In AG group, E 2 level was positively correlated with T and Crea ( r=0.234, P=0.024; r=0.245, P=0.018), T level was positively correlated with Crea ( r=0.349, P=0.001), and negatively correlated with apob1 ( r=-0.250, P=0.016), and E 2/T was positively correlated with apob1 ( r=0.276, P=0.007). In IG group, E 2 level was positively correlated with T ( r=0.269, P=0.003), and negatively correlated with MO ( r=-0.183, P=0.048), while P level was positively correlated with MO( r=0.204, P=0.027). Conclusion:The expression of E 2 and T in the peripheral blood serum of gout patients decreases significantly, the expression of P and E 2/T increases significantly, and there is a positive correlation between E 2 and T, as well as the inflammatory and glycolipid metabolism indexes of gout patients, suggesting that estrogen, androgen and progesterone may participate in the pathogenesis of gout by regulating the inflammation and metabolism of gout.

ABSTRACT

Objective To observe biomechanical characteristics and advantages of the self-developed anatomical locking plate of sternoclavicular joint by comparison with the radial distal oblique T-shaped locking plate and sternoclavicular hook plate. Methods Nine embalming and moistening adult corpses were selected, including 6 males and 3 females. Model of complete dislocation of the sternoclavicular joint caused by complete removal of the sternoclavicular joint specimen. The bilateral sternoclavicular joints of 9 specimen models were randomly numbered, matched and divided into Group A(experimental group, sternoclavicular joint anatomical locking plate), Group B(control group 1, the radial distal oblique T-shaped locking plate) and Group C(control group 2, sternoclavicular hook plate), with 6 sternoclavicular joints in each group. All specimens were placed with steel plates on both sides and fixed on the universal mechanical test machine. Three biomechanical experiments were carried out, including loading of distal clavicle, torsion of distal clavicle and anti-pull out of sternum handle screw. Results Distal clavicle loading test: the load-displacement of specimens in three groups showed a linear relationship. The compressive deformation resistance in experimental group was stronger than that in two control groups. Distal clavicle torsion test: the relationship between torque and torsion angle was linear. The torsional deformation resistance in experimental group was stronger than that in two control groups. Anti-pullout test of sternum handle screw: there was a significant difference in the maximum anti-pullout force of sternum handle screw among the three groups (P<0.05). The anti-pullout performance of the sternum handle screw in the experimental group was better than that in the two control groups. Conclusions The self-developed sternoclavicular joint anatomical locking plate is superior to the oblique T-shaped locking plate of distal radius and the plate of sternoclavicular hook in terms of anti-compression, anti-torsion and anti-pullout of sternoclavicular screw, so as to provide an ideal internal fixation device for the treatment of fracture and dislocation of sternoclavicular joint.

ABSTRACT

OBJECTIVE@#To analyze the relation between the signle nucleotide polymorphisms (SNP) of CYP3A5 gene and MDR1 gene loci and the risk of cytogenetic relapse in chronic myeloid leukemia (CML).@*METHODS@#The clinical data of 90 patients with CML treated with imatinib in our hospital were collected.The patients were divided into 2 groups: non-relapse and relapse according to relapse and non-relapse, then the relation between the SNP of CYP3A5 gene and MRD1 gene loci and the risk of cytogenetic relapse in CML patients.@*RESULTS@#The grouping result showed that the patients with non cytogenetic relapse accounted for 41 cases those were enrolled in non-relapse group, and patient-with cytogenetic relapse accounted for 49 cases those were enrolled in relapse group. The follow-up time was 36 months. The detection showed that the incidence of cytogenetic relapse in the patients with CC genotype was significantly higher than that in the patients with TT+CT genotype of C3435T and C1236T at MDR1 gene loci (P<0.05).Compared with the patients with CT+CC genotype in C3435T locus of MDR1 gene, the rate of cytogenetic relapse in the patients with TT genotype decreased significantly (P<0.05). Compared with patients with CT+CC phemotype of C3435T in MDR1 gene locus, the non-relapse survival time of TT genotypes was significantly prolonged (P<0.05). Compared with non-relapse group, the incidence of neutropenia (29.27% vs 71.43%) and blood toxicity (39.02% vs 61.22%) in the relapse group increased significantly (P<0.05). The imatinib dose (OR=2 95, 95% CI:1.37~7.76) and the C3435T genotype in MDR1 genes (OR=0.09, 95% CI:0.05~0.72) were the factors affecting the cytogenetic relapse of the patients with CML (both P<0.05).@*CONCLUSION@#The therapeutic dose of imatinib and the C3435T and C1236T genotypes in MDR1 gene have a certain effect on the cytogenetic relapse of CML patients. C3435T genotypes in the.MDR1 gene showed a certain predictive value for evaluating the risk of cytogenetic relapse, which can be used as a clinical biomarker.

ABSTRACT

Traditional Chinese herbs are readily contaminated by mold that produced mycotoxins which are closly related to the herbs' external factors and external environments during the storage process. In this study, Citri Reticulatae Pericarpium was used as example, and the characteristics of traits, water content, active components (naringin, hesperidin, sinensetin, naringin, tangeretin) and the accumulation of aflatoxins (AFs) were selected as the evaluation indexes. Citri Reticulatae Pericarpium was stored under different environments and packaging materials for 12 months, and then the quality changes and mildew of Citri Reticulatae Pericarpium were examined. The results showed that the color of Citri Reticulatae Pericarpium was deepened after storage, but without mildew phenomenon. Besides, the sample storage in kraft paper and woven bags had varying degrees of moth phenomenon after 12 months storage, and the water content exceeded the limit of Chinese Pharmacopoeia. In addition, the contents of the five active constituents obviously decreased, especially for hesperidin, which did not meet the pharmacopoeia standard after storage. AFs were not detected in any of the tested samples. According to the results, we conclude that low temperature and humidity environment is more suitable for the storage of Citri Reticulatae Pericarpium, and that packaging materials should be further investigated. This study is of great significance for preventing the mold to contaminate the traditional Chinese medicine and ensuring the quality, effectiveness and safety of TCMs.

ABSTRACT

Objective To compare the clinical effect of endoscopic thyroidectomy and open thyroidectomy in the treat-ment of benign thyroid diseases. Methods A total of 120 patients with benign thyroid diseases were selected from March 2015 to June 2017 in the Third Affiliated Hospital of Xinxiang Medical University. The patients were divided into endoscopic opera-tion group(n = 62)and open operation group(n = 58)according to the treatment methods. The patients in the open operation group were treated with conventional open thyroidectomy,and the patients in the endoscopic operation group were treated with endoscopic thyroidectomy. The operation time,intraoperative bleeding volume,postoperative drainage volume and hospitalization time were recorded in the two groups;and the intraoperative and postoperative complications were observed. The pain of the pa-tients in the two groups was evaluated by visual analogue scale(VAS)at the time points of 6,12 and 24 hours after operation. The cosmetic satisfaction of the patients in the two groups was evaluated by numerical scoring system(NSS)at the time points of 1 and 3 months after operation. Results The operation time and hospitalization time in the endoscopic operation group were significantly shorter than those in the open operation group(P < 0. 05),and the intraoperative bleeding volume and postopera-tive drainage volume in the endoscopic operation group were significantly lower than those in the open operation group(P <0. 05). The VAS score of pain in the endoscopic operation group was significantly lower than that in the open operation group at the time points of 6,12 and 24 hours after operation(P < 0. 05). The NSS score in the endoscopic operation group was sig-nificantly higher than that in the open operation group at the time points of 1 and 3 months after operation(P < 0. 05). The in-cidence of complications in the endoscopic operation group and the open operation group was 12. 90%(8 / 62)and 39. 66%(23 / 58)respectively,the incidence of complications in the endoscopic operation group was significantly lower than that in the open operation group(χ2 = 11. 210,P < 0. 05). Conclusion Endoscopic thyroidectomy is reliable in the treatment of benign thyroid diseases. It has the advantages of small trauma,short operation time,quick recovery,light postoperative pain,small sur-gical scar and fewer complications and so on.

ABSTRACT

<p><b>BACKGROUND</b>Some esophageal cancer patients complicated with depression exhibit cognitive impairments. Frontal electroencephalogram (EEG) may be used as a reliable biomarker for prefrontal-mediated cognitive functions. This study was to investigate alterations of EEG and frontal cognitive impairment in esophageal cancer patients complicated with depression and to assess their correlation.</p><p><b>METHODS</b>Sixty-five esophageal cancer patients with depression (study group) and 62 healthy controls (control group) were included in this study. The study group were assigned into psychotic depressed (PD, n = 32) and nonpsychotic depressed (NPD, n = 33) subgroups based on complication with psychotic symptoms (Brief Psychiatric Rating Scale [BPRS] >35). EEG examination, Beck self-rating depression scale, and BPRS were used to assess clinical symptoms. Chi-square test, two independent sample t-test, one-way analysis of variance, and Kruskal-Wallis test were utilized to compare the variables between two groups. EEG abnormalities and scores of frontal cognitive function test were analyzed by partial correlation analysis in the PD and NPD subgroups.</p><p><b>RESULTS</b>Compared with control group, the study group displayed greater scores either in the Stroop test (19.89 ± 2.05 vs. 24.12 ± 2.19, P = 0.006) or Color Trails Test (CTT; 11.92 ± 1.01 vs. 15.02 ± 1.63, P = 0.008), and reduced score (35.05 ± 2.01 vs. 32.11 ± 2.38, P = 0.007) in the verbal fluency test (VFT). Compared to NPD subgroup, PD subgroup exhibited increased scores in Stroop test (22.89 ± 2.07 vs. 25.38 ± 2.32, P = 0.009) and CTT (13.16 ± 1.71 vs. 15.82 ± 1.13, P = 0.008). Moreover, increased scores in Stroop test and CTT as well as scores in VFT were associated with the severity of depression. The study group had an abnormal frontal EEG, such as α forward, α asymmetry, α moderation, and increased θ activity relative to control group. Similarly, compared with NPD subgroup, PD subgroup displayed α forward, α asymmetry, and α moderation. The correlation test revealed that α forward and α asymmetry were negatively associated with VFT score, but positively correlated with the scores of CTT and the Stroop test in PD subgroup. In addition, α asymmetry in NPD subgroup was positively related to CTT scores.</p><p><b>CONCLUSION</b>This study indicated that frontal cognitive impairment in esophageal cancer patients complicated with depression is associated with EEG alterations.</p>

BACKGROUND:Acellular nerve scaffolds have the three-dimensional structure of natural nerves and low immunogenicity,but their effect on long nerve defects is still not ideal.Therefore,it is necessary to construct tissueengineered nerve using acellular nerve and seed cells in order to improve the therapeutic effect.OBJECTIVE:To systemically review the efficacy of combination of acellular nerve grafts (ANGs) and mesenchymal stem cells (MSCs) or Schwann cells (SCs) transplantation in the treatment of sciatic nerve defects in a rat model.METHODS:Randomized controlled trials (RCTs) about the effects of combination of ANGs and MSCs or SCs transplantation for sciatic nerve defects in rats were searched in PubMed,The Cochrane Library,EMbase,CNKI,WanFang and VIP from inception to July 2016.Three reviewers independently screened literature according to the inclusion and exclusion criteria,extracted data,and assessed the risk of bias of included studies.Then,a Meta-analysis was performed using Review Manger5.3 software.RESULTS AND CONCLUSION:A total of 10 RCTs involving 252 rats were included.The results of meta-analysis showed that:compared with the control group (simple acellular nerve scaffold group),the sciatic functional index (SFI) of the combined group (combination of ANGs and MSCs or SCs transplantation) were superior at 2 weeks [SMD=2.73,95% CI (1.92,3.45),P < 0.000 01],4 weeks [SMD=4.57,95% CI (3.43,5.70),P < 0.000 01],6 weeks [SMD=1.62,95%CI (0.18,3.06),P=-0.03],8 weeks [SMD=4.90,95% CI (2.96,6.84),P < 0.000 01] after surgery.The nerve conduction velocity [SMD=1.39,95% CI (0.99,1.78),P < 0.000 01),latency period (MD=-0.98,95% CI (-1.19,-0.76),P < 0.000 01],and amplitude [SMD=1.23,95% CI (0.62,1.85),P < 0.000 1] were superior at 12 weeks after surgery.The myelin sheath thickness was superior at 8 weeks [MD=0.14,95% CI (0.07,0.21),P < 0.000 1],12 weeks [SMD=1.85,95% CI (1.63,2.08),P < 0.000 01] and the number of myelinated nerve fibers were superior at 12 weeks [SMD=3.59,95%CI (2.63,4.55),P < 0.000 01] after surgery.The gastrocnemius wet weight was superior at 8 weeks after surgery [SMD=4.22,95% CI (2.40,6.03),P < 0.000 01].Current evidence indicates that the combination of ANGs and MSCs or SCs can promote the regeneration and functional recovery of the peripheral nerve.Due to the limited quality of the included studies,the above conclusion should be verified by conducting high-quality and large-scale RCTs.

ABSTRACT

Menthae Haplocalycis Herba has been widely applied in such fields as food, cosmetics, daily necessities, medicine and health, due to its unique efficacy. However, as the safety of traditional Chinese medicines has been of increasing concern, the quality issue of Menthae Haplocalycis Herba and its decoction slices has become a key obstructive factor for exports. This article focused on the control over Menthae Haplocalycis Herba's adulterants, exogenous hazardous residues and internal properties (chemical compositions, spectrum effect relationship). Moreover, current studies on the quality of Menthae Haplocalycis Herba and its decoction slices, as well as the existing problems in recent years were systematically summarized in the expectation of improving the means of quality control of Menthae Haplocalycis Herba and its decoction slices, enhancing its quality standards, and ensuring the use safety and effectiveness.

ABSTRACT

<p><b>BACKGROUND</b>The clotting system abnormalities are the common complication in cancer patients. The aim of this retrospective study was to evaluate the coagulation state, clinical features, and treatment in cancer patients by routine tests.</p><p><b>METHODS</b>A total of 2328 patients with different types of cancer were classified as the positive group (n = 1419, including 53 patients with thrombosis) and the negative group (n = 909) based on D-dimer (DD) value. Of the 2328 cases, 354 were admitted for chemotherapy. Hemostasis test and complete blood count (CBC) were performed during treatment or following-up.</p><p><b>RESULTS</b>This study showed that the hypercoagulable state was affected not only by clinical staging (P < 0.0001) but also by metastasis site (P < 0.0001 for bone vs. lung). Compared to negative DD group, the higher fibrinogen level, the extended activated partial thromboplastin time, and prothrombin time interacted markedly with disease clinical stage (P < 0.05) in the positive group. Between positive DD groups with and without thrombus, the significantly statistic difference in white blood cell (WBC) and DD (P < 0.05) rather than in red blood cell (RBC) and platelet count was observed. However, the higher DD level was not correlated with WBC, RBC, and platelet count in the positive DD group. Furthermore, the hypercoagulable plasma profile in cancer patients was moderated 2-3 weeks after chemotherapy (P < 0.05 for first six cycles).</p><p><b>CONCLUSIONS</b>The routine hemostatic parameters and CBC are valuable to assessment for thrombosis and chemotherapy even for disease prognosis.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the molecular genetic abnormalities of N-myc and C-myc, and their clinical pathological implications in pediatric neuroblastic tumors (NTs).</p><p><b>METHODS</b>Abnormalities of N-myc were detected by interphase fluorescence in situ hybridization (FISH) technique in 246 cases of NTs, including neuroblastoma (NB,188 cases), ganglioneuroblastoma (GNB, 52 cases), ganglioneuroma (GN, 6 cases), and their association with the histological typing of the tumors and prognosis was analyzed. Abnormalities of C-myc were detected by FISH in 133 cases of NTs.</p><p><b>RESULTS</b>Of the 246 cases of NTs, N-myc amplification was only found in 27 cases (11.0%, 27/246) of NB, but not in any cases of GNB or GN (P < 0.05). 89.0% (219/246) N-myc non-amplification were found in NTs, and it included N-myc gain in 175 cases (71.1%, 175/246) and normal N-myc in 44 cases (17.9%, 44/246). Univariate analysis indicated significantly (P = 0.012) poorer outcome in patients with N-myc amplification than N-myc non-amplification. However no significant difference was observed between N-myc gain cases and normal N-myc cases (P = 0.057). C-myc gain was found in 74 of 133 cases (55.6%) of NTs; no C-myc amplification or translocation was detected. Forty percent (6/15) of cases with N-myc amplification and 57.6% (68/118) of cases with N-myc non-amplification were accompanied by C-myc gain. The difference between N-myc amplification and non-amplification with C-myc gain was not significant (P > 0.05). Univariate analysis indicated that the outcome difference was not statistically significant between C-myc gain cases and normal C-myc cases (P = 0.357).</p><p><b>CONCLUSIONS</b>The incidence of N-myc amplification only found in NB is low in pediatric NTs in China. Patients with N-myc amplification predict poorer outcome. No amplification or translocation of C-myc is detected in NTs, whereas C-myc gain is relatively common in NTs. There is no obvious association between N-myc amplification and C-myc gain.</p>

ABSTRACT

This study was purposed to analyze the relation of N-myc gene copy number with clinical staging, pathological types and tumor biological factors in children with neuroblastoma (NB), and to investigate the influence of chemotherapy on N-myc gene expression and explore the relationship of N-myc gene copies with prognosis of NB children. The newly diagnosed children with NB from 1 March 2007 to 31 January 2011 were enrolled in this study. The treatment was carried out by BCH-NB-2007 based on Hongkong NB-07 protocol, and the patients were follow up to 31 January 2012. The N-myc gene in NB children was detected by FISH. According to number of N-myc gene copies, the NB children were divided into 3 groups. A group (N-myc gene negative) had less than 2 copies, B group (N-myc gene gains) had 3 to 9 copies, and C group (N-myc amplification) had more than 10 copies. The results showed that the N-myc gene expression in 58 cases of NB was observed. There were 36 males and 22 females. NB children aged from 6.5 to 138 months (median age 47.5 months), all patients were followed up for 11 - 57 months with an average of 31.5 months. INSS stages I-IV were 1, 5, 8 and 44 cases, respectively. Twenty-five cases had primary post mediastinal tumor, thirty-three cases had retroperitoneal and pelvic tumor, three of which also companied with post mediastinal tumor. Thirty-five cases had bone metastasis (60.3%), thirty-two cases had bone marrow metastasis (55%). Of the 54 patients with fully known biologic features, seventeen cases had ganglioneuroblastoma, thirty-seven cases had neuroblastoma (15 displayed differentiated, 7 poorly differentiated or undifferentiated, 15 with pathological changes after chemotherapy), four cases had bone marrow metastasis only detected by bone marrow biopsy. Eleven cases had N-myc gene negative, forty-three had N-myc gains, four had N-myc amplification. The average copy number of N-myc gene copies in 58 cases was 5.96 ± 7.81 in which 28 children were non chemotherapy cases, their average copy number was 4.00 ± 1.88, thirty cases out of 58 cases received preoperation chemotherapy (chemotherapy group), and their average copy number was 7.80 ± 10.46, the difference is significant (P = 0.064). The clinic stage, the location of primary tumor, pathological classification, urine VMA and serum neurogenic specific enolase had no effects on the N-myc gene expression, but the serum LDH level had influence (P < 0.01). Single factor Kaplan-Meier analysis showed that the number of N-myc gene copies in NB patients were closely related with the poor prognosis. The more copies of N-myc gene, the more poor prognosis, the difference is statistically significant (P < 0.05). It is concluded that the number of N-myc gene copies correlates with the rapid growth of NB and its poor prognosis, detecting the N-myc amplification can help to estimate the prognosis and decide the program of treatment. Serum LDH, which correlated with the rapid growth of NB, had effect on the N-myc gene expression and is closely related with the poor prognosis of NB.
