Abstract
Background: Non-Hodgkin's lymphoma (NHL) is an aggressive malignancy. Its outcome has improved over the past decades. Although it accounts for 8%–10% of all childhood cancers, very less information about its clinical presentation and outcomes is available from India. Our objective was to study the clinical presentation and outcomes in children (<15 years) with NHL at our center. Methodology: We retrospectively analyzed 26 children diagnosed with NHL at our center from August 2008 to June 2014 and followed them up to May 2017. Results: The median age at the time of diagnosis was 7.7 years (2.5–13 years). Abdominal distension and an abdominal lump were the most common presenting features occurring in 75%, followed by fever (73.8%) and weight loss (46.2%). Most patients had advanced-stage (Stage III/IV, 92.3%) disease at presentation. The primary presentation was extranodal in 57.7%, nodal in 26.9%, and combined in 15.4%. Burkitt's lymphoma (BL) was the most common subtype (46.2%), followed by T-lymphoblastic lymphoma, diffuse large B-cell lymphoma, and anaplastic large-cell lymphoma. Three patients did not take treatment. The median follow-up of patients was 48 months (36–99 months). Nineteen patients achieved remission and four had progressive disease. Significantly better event-free survival (EFS) was found with younger age and lower stage of presentation. The EFS did not significantly differ with sex, group of disease, lactate dehydrogenase levels, and presenting features. Conclusions: Our cohort of patients with NHL showed characteristics similar to those reported from other developing countries. NHL occurred at a younger age, with a higher incidence of BL. The outcome for patients aged >10 years was poor. The outcome of NHL was comparable to that of other centers in the world.

Lack of Impact of the A1298C MTHFR on the Risk of Childhood Acute Lymphoblastic Leukemia: Evidence from a Meta-analysis. Indian J Hematol Blood Transfus 2021; 38:255-263. [PMID: 35496972 PMCID: PMC9001782 DOI: 10.1007/s12288-021-01453-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2021] [Accepted: 05/15/2021] [Indexed: 10/21/2022] Open
Abstract
To clarify the effect of the A1298C variant of methylenetetrahydrofolate reductase (MTHFR) gene on the risk of acute lymphoblastic leukemia (ALL), an updated meta-analysis was performed. Electronic literature search was carried out in PubMed to collect relevant articles. Pooled odds ratios (OR) and stratification analysis were achieved under different genetic comparison models, age and ethnicity. A total of 46 articles including 7020 cases and 12,114 controls were enrolled. Overall, no significant association was observed for the MTHFR A1298C variant on the risk of ALL in any genetic model test, when all the studies pooled together (OR ~ 1 0.91; p > 0.05). In subgroup analyses stratified by age and ethnicity, the MTHFR A1298C reduce the risk of ALL in adult under allele contrast (OR = 0.88; [0.72; 1.09], p = 0.23) mainly in Caucasian populations. The present meta-analysis provides evidence that the A1298C variant of MTHFR gene is unlikely to be a major risk gene for childhood ALL.

Abstract
The aim of this study was to investigate the association of methylenetetrahydrofolate reductase (MTHFR) gene polymorphism and additional gene-gene interaction with acute lymphoblastic leukemia (ALL) risk. Logistic regression was performed to investigate the association between two single nucleotide polymorphisms (SNPs) within MTHFR gene and ALL risk and additional gene-gene interaction between rs1801133 and rs1801131. The minor allele of rs1801133 and rs1801131 is associated with decreased ALL risk, OR (95% CI) were 0.61 (0.38-0.89), and 0.68 (0.50-0.96), respectively. We also found a significantly interaction between the two SNPs, participants with rs1801133 - CT or TT and rs1801131 - AC or CC genotype have the lowest ALL risk, compared with participants with rs1801133 - CC and rs1801131 - AA genotype, OR (95% CI) was 0.32 (0.12-0.63). We did not find any haplotype between the rs1801133 and rs1801131 associated with ALL risk. rs1801133 and rs1801131 within MTHFR gene and their interaction were both associated with ALL risk in Chinese children.

Abstract
BACKGROUND Genetic polymorphisms in patients with acute lymphoblastic leukemia (ALL) may influence the toxicity of chemotherapeutic agents. Due to the importance of the transport P-glycoprotein and methylenetetrahydrofolate reductase in the metabolism of chemotherapeutic agents, we analyzed the MDR1 rs1045642 and MTHFR rs1801133 polymorphisms and their associations with clinical outcomes in Mexican childhood ALL patients. METHODS A total of 109 patients participated in this study. The clinical evaluation consisted of a physical examination and a laboratory test. Genotyping of MDR1 rs1045642 (3435 C>T) and MTHFR rs1801133 (677 C>T) was performed by polymerase chain reaction/restriction fragment length polymorphism. Statistical analyses were performed using SPSS 14.0. The odds ratios and 95% confidence intervals (CI) were estimated by logistic regression. RESULTS Individuals who were CC homozygotes at MDR1 rs1045642 had lower risk of having methotrexate plasma concentrations >1 μM and leukopenia grade I (odds ratio [OR] = 0.30; 95% CI = 0.13-0.72 and OR = 0.32; 95% CI = 0.14-0.72, respectively). Patients who were CC homozygotes at MTHFR rs1801133 had a higher risk of developing mucositis (OR = 3.61; 95% CI = 1.42-9.14). CONCLUSION MDR1 rs1045642 and MTHFR rs1801133 should be considered as diagnostic candidates for the identification of pediatric patients with a high risk of suffering adverse events during ALL treatment.

Abstract
Background Acute lymphoblastic leukemia (ALL) is the most prevalent type of pediatric cancer, the causes of which are likely to involve an interaction between genetic and environmental factors. To evaluate the effects of the genotypic polymorphisms in methylenetetrahydrofolate reductase (MTHFR) on childhood ALL risk in Taiwan, two well-known polymorphic genotypes of MTHFR, C677T (rs1801133) and A1298C (rs1801131), were analyzed to examine the extent of their associations with childhood ALL susceptibility and to discuss the MTHFR genotypic contribution to childhood ALL risk among different populations. Methodology/Principal Findings In total, 266 patients with childhood ALL and an equal number of non-cancer controls recruited were genotyped utilizing PCR-RFLP methodology. The MTHFR C677T genotype, but not the A1298C, was differently distributed between childhood ALL and control groups. The CT and TT of MTHFR C677T genotypes were significantly more frequently found in controls than in childhood ALL patients (odds ratios=0.60 and 0.48, 95% confidence intervals=0.42–0.87 and 0.24–0.97, respectively). As for gender, the boys carrying the MTHFR C677T CT or TT genotype conferred a lower odds ratio of 0.51 (95% confidence interval=0.32–0.81, P=0.0113) for childhood ALL. As for age, those equal to or greater than 3.5 years of age at onset of disease carrying the MTHFR C677T CT or TT genotype were of lower risk (odds ratio= 0.43 and 95% confidence interval=0.26–0.71, P=0.0016). Conclusions Our results indicated that the MTHFR C677T T allele was a protective biomarker for childhood ALL in Taiwan, and the association was more significant in male patients and in patients 3.5 years of age or older at onset of disease.

Abstract
Background Studies and systematic reviews have reached inconsistent conclusions on the role of 5, 10-methylenetetrahydrofolate reductase (MTHFR) polymorphism C677T in acute lymphoblastic leukemia (ALL) risk. Material/Methods The present meta-analysis comprising of 51 case-control studies, including 7892 cases and 14 280 controls was performed to reevaluate the association between MTHFR C677T polymorphism and ALL risk. Results Statistical differences were found in the dominant model (TT+CT vs. CC, odd ratio (OR)=0.89, 95% CI, 0.79–1.00, P=0.04) and the CT vs. CC (OR=0.89, 95% CI, 0.80–1.00, P=0.05), but not in the allele contrast model (T vs. C, OR=0.92, 95% CI, 0.84–1.01, P=0.08), additive model (TT vs. CC, OR=0.87, 95% CI, 0.73–1.05, P=0.15), or recessive model (TT vs. CT+CC, OR=0.94, 95% CI, 0.81–1.10, P=0.44) in overall populations. In the subgroup analyses stratified by age (children and adults) and ethnicity (Asian and Caucasian), no significant associations between MTHFR C677T polymorphism and ALL risk were observed. Conclusions The current study found no sufficient evidence of a protective role of MTHFR C677T polymorphism in ALL susceptibility.

Abstract
Studies on the association of methylenetetrahydrofolate reductase (MTHFR) genotype in childhood acute lymphoblastic leukemia (ALL) have yielded conflicting results. The present study examines this association in north Indian children with ALL and includes an updated meta-analysis. MTHFR (677 and 1298) genotype of children with ALL and healthy adult controls were done by the PCR-restriction fragment length polymorphism (PCR-RFLP) method and were compared using various models of inheritance. A total of 150 patients and 300 controls were included. The 677T allele was found protective (odds ratio (OR) 0.21, 95% confidence interval (CI) 0.04-0.94), whereas 1298C allele led to an increase in risk (OR 4.44, 95% CI 2.19-8.99) of childhood ALL. Meta-analysis included 31 and 27 studies examining the association of 677 and 1298 genotypes, respectively. The 677 C -> T polymorphism was protective (OR 0.90, 95% CI 0.82-0.99). Protection was more pronounced in folate-sufficient populations as compared with those not covered by folate fortification guidelines. The 1298A->C polymorphism was associated with a marginal increase in risk (OR 1.19, 95% CI 1.01-1.40).

Abstract
Objective. Methotrexate (MTX), the most used drug in rheumatoid arthritis (RA) treatment, showing variability in clinical response, is often associated with genetic polymorphisms. This study aimed to elucidate the role of methylenetetrahydrofolate reductase (MTHFR) C677T and aminoimidazole carboxamide adenosine ribonucleotide transformylase (ATIC) T675C polymorphisms and clinicopathological variables in clinical response to MTX in Portuguese RA patients. Methods. Study included 233 RA patients treated with MTX for at least six months. MTHFR C677T and ATIC T675C polymorphisms were genotyped and clinicopathological variables were collected. Statistical analyses were performed and binary logistic regression method adjusted to possible confounding variables. Results. Multivariate analyses demonstrated that MTHFR 677TT (OR = 4.63; P = 0.013) and ATIC 675T carriers (OR = 5.16; P = 0.013) were associated with over 4-fold increased risk for nonresponse. For clinicopathological variables, noncurrent smokers (OR = 7.98; P = 0.001), patients positive to anti-cyclic citrullinated peptide (OR = 3.53; P = 0.004) and antinuclear antibodies (OR = 2.28; P = 0.045), with higher health assessment questionnaire score (OR = 2.42; P = 0.007), and nonsteroidal anti-inflammatory drug users (OR = 2.77; P = 0.018) were also associated with nonresponse. Contrarily, subcutaneous administration route (OR = 0.11; P < 0.001) was associated with response. Conclusion. Our study suggests that MTHFR C677T and ATIC T675C genotyping combined with clinicopathological data may help to identify patients whom will not benefit from MTX treatment and, therefore, assist clinicians in personalizing RA treatment.

Abstract
Methylenetetrahydrofolate reductase (MTHFR) is an important enzyme involved in folate metabolism, which is essential for DNA synthesis and methylation. Genetic variations in the MTHFR gene seem to contribute to a decreased activity of MTHFR, ultimately confer increased susceptibility to cancer. As the most extensively studied polymorphism, MTHFR C677T polymorphism was shown to contribute to cancer susceptibility but the results were inconsistent. The authors performed a meta-analysis including 134 studies (46,207 cases and 69,160 controls) to address the issue. Odds ratios (ORs) with corresponding 95% confidence intervals (CIs) were used to assess the association. Overall, a significant elevated risk of cancer was associated with the MTHFR C677T polymorphism in T-allele versus C-allele comparison (OR = 1.06, 95% CI 1.02-1.11, P(heterogeneity) < 0.001), homozygote model (OR = 1.08, 95% CI 1.01-1.17, P(heterogeneity) < 0.001) and dominant model (OR = 1.05, 95% CI 1.00-1.10, P(heterogeneity) < 0.001). In the stratified analyses, significantly increased cancer risks were indicated among Asians in all genetic models except for heterozygote model. Further analysis revealed that C677T was significantly associated with an increased risk of esophageal and stomach cancer. This meta-analysis supports an association between the MTHFR C677T polymorphism and increased risk of esophageal and stomach cancer, especially among Asians. Additionally, more high-quality studies and that the covariates responsible for heterogeneity should be controlled to obtain a more conclusive response about the function of MTHFR C677T in cancer.

Abstract
Genetic polymorphisms in the methylene tetrahydrofolate reductase (MTHFR) gene have been associated with the development of acute leukemias and various malignancies. The role of MTHFR polymorphism in the development of pediatric acute lymphoblastic leukemia (ALL) has been extensively studied among north Indians in various settings, yet its association with acute leukemias remains unresolved. To evaluate the relationship between functional MTHFR polymorphisms, C677T and A1298C and possible effect on risk of ALL in adults and children in North Indian population by comparing them with healthy controls. DNA was isolated from peripheral blood of 184 ALL patients (33 adults, 151 children) and 155 controls and analyzed by a PCR-restriction fragment length polymorphism assay. The frequency of MTHFR 677CT and 1298 AC genotypes were significantly lower among adult ALL cases when compared to the controls. We found a 1.74-fold reduced risk of ALL in individuals with 1298AC polymorphic variant and a 9.17-fold decreased risk of adult ALL. However, no statistically significant difference was evident between the above polymorphisms and susceptibility to ALL in children. Polymorphisms in the MTHFR gene possibly modulate risk of ALL in north Indian adults but not in children, although larger studies are needed.

Abstract
5,10-Methlenetetrahydrofolate reductase (MTHFR) is one of the most important enzymes for folate metabolism. This enzyme is mapped on chromosome 1, which is located at the end of the short arm (1p36.3). The C677T and A1298C are MTHFR polymorphisms that decrease in vitro MTHFR enzyme activity. Folate metabolism plays a key role in cell metabolism. These reactions are associated with purine-pyrimidine synthesis: DNA, RNA, and protein methylation. Polymorphism is also a factor in biodiversity, and be affected by ethnic heritage and geographic locale. In the case of unknown outcomes, not only should all geographical regions be investigated to ascertain biodiversity, but all populations as well to fully understand the variations in the effect. PUBMED was searched from January 2006 to December 2011 to develop an investigatory pursuit strategy. MTHFR, cancer, C677T, A1298C, and polymorphisms were key words used to focus the search. The literature review included all published relevant cancer types and MTHFR polymorphisms for that 5 years period. All selected polymorphisms data for cancer types was listed in tables for easy access and retrieval.

BMC MEDICAL GENETICS 2012; 13:77. [PMID: 22943282 PMCID: PMC3459788 DOI: 10.1186/1471-2350-13-77] [Citation(s) in RCA: 30] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/31/2011] [Accepted: 08/27/2012] [Indexed: 11/25/2022]
Abstract
Background 5,10-methylenetetrahydrofolate reductase (MTHFR) variants, C677T and A1298C, have been reported to be associated with decreased risk of acute lymphoblastic leukemia (ALL). However, results derived from individually underpowered studies are conflicting. We carried out an updated meta-analysis on the association between MTHFR polymorphisms and ALL risk. Methods Relevant publications were searched through PUBMED and EMBASE databases. The associations between MTHFR C677T and A1298C polymorphisms and the risk of ALL were evaluated by odds ratios (ORs). The heterogeneity and publication bias were estimated. Meta-regression analysis was performed to evaluate the potential sources of heterogeneity. Results C677T polymorphism was associated with a reduced risk of ALL (allele contrast: ORRE = 0.91, 95% CI: 0.83-0.99). Subgroup analysis showed MTHFR C677T variant was associated with decreased susceptibility to ALL in children and Caucasians. Meta-regression showed the logOR for the association between T allele and ALL increased as sex ratio (M/F) in the case group increased (P = 0.01). Regarding A1298C polymorphism, no significant association was observed (allele contrast: ORRE = 1.01, 95% CI: 0.91-1.11). There was no publication bias for C677T or A1298C polymorphism. Conclusions The present meta-analysis suggests that the C677T polymorphism, not A1298C, in MTHFR gene is associated with a decreased risk of ALL, particularly among children and Caucasians subjects. Our findings suggest that the influence of the C677T polymorphism on ALL susceptibility is modified by sex ratio in cases (M/F). Since folate intake may be a possible confounding factor, including this factor in future prospective studies is warranted. Further meta-analysis studies should be at least stratified for folate levels and gender to give more powerful and informative results.

Abstract
BACKGROUND Methylenetetrahydrofolate reductase (MTHFR) C677T and A1298C polymorphisms have been implicated in childhood acute lymphoblastic leukemia (ALL) risk, but previously published studies were inconsistent and recent meta-analyses were not adequate. PROCEDURES In a meta-analysis of 21 publications with 4,706 cases and 7,414 controls, we used more stringent inclusion method and summarized data on associations between MTHFR C677T and A1298C polymorphisms and childhood ALL risk. RESULTS We found an overall association between 677T variant genotypes and reduced childhood ALL risk. Specifically, in the dominant genetic model, an association was found in a fixed-effect (TT + CT vs. CC: OR = 0.92; 95% CI = 0.85-0.99) but not random-effect model, whereas such an association was observed in both homozygote genetic model (TT vs. CC: OR = 0.80; 95% CI = 0.70-0.93 by fixed effects and OR = 0.78; 95% CI = 0.65-0.93 by random effects) and recessive genetic model (TT vs. CC + CT: OR = 0.83; 95% CI = 0.72-0.95 by fixed effects and OR = 0.84; 95% CI = 0.73-0.97 by random effects). These associations were also observed in subgroups by ethnicity: for Asians in all models except for the dominant genetic model by random effect and for Caucasians in all models except for the recessive genetic model. However, the A1298C polymorphism did not appear to have an effect on childhood ALL risk. CONCLUSIONS These results suggest that the MTHFR C677T, but not A1298C, polymorphism is a potential biomarker for childhood ALL risk.

Variants of the MTHFR gene and susceptibility to acute lymphoblastic leukemia in children: a synthesis of genetic association studies. Cancer Epidemiol 2011; 36:169-76.

Abstract
BACKGROUND Acute lymphoblastic leukemia (ALL) is a complex disease with genetic background. The genetic association studies (GAS) that investigated the association between ALL and the MTHFR C677T and A1298C gene variants have produced contradictory or inconclusive results. MATERIALS AND METHODS In order to decrease the uncertainty of estimated genetic risk effects, a meticulous meta-analysis of published GAS related the variants in the MTFHR gene with susceptibility to ALL was conducted. The risk effects were estimated based on the odds ratio (OR) of the allele contrast and the generalized odds ratio (OR(G)). Cumulative and recursive cumulative meta-analyses were also performed. RESULTS The analysis showed marginal significant association for the C677T variant, overall [OR=0.91 (0.82-1.00) and OR(G)=0.89 (0.79-1.01)], and in Whites [OR=0.88 (0.77-0.99) and OR(G)=0.85 (0.73-0.99)]. The A1298C variant produced non-significant results. For both variants, the cumulative meta-analysis did not show a trend of association as evidence accumulates and the recursive cumulative meta-analysis indicated lack of sufficient evidence for denying or claiming an association. CONCLUSION The current evidence is not sufficient to draw definite conclusions regarding the association of MTHFR variants and development of ALL.

Abstract
BACKGROUND There is a dearth of published literature on the frequency and distribution of pediatric and adolescent non-Hodgkin lymphoma (NHL) in India according to the 2001 WHO classification. The aim of this study was to record the distribution of the different subtypes, analyze the major subtypes, and compare it with the published data from other countries. A review of pediatric NHL statistics from population-based cancer registries was included in this study. METHODS The study was conducted using information retrieved from the files of our institution. A total of 467 patients with lymphoma (excluding mycosis fungoides) were recorded in the under 20 years group over a period of 6 years, of which 252 patients suffered from NHL. The demographic characteristics, frequency and distribution of different subtypes were noted and compared with published reports from other parts of the world. RESULTS T-lymphoblastic lymphoma/leukemia constituted the majority (32.1%) of all NHLs in children and adolescents in our study. The other major subgroups were Burkitt's lymphoma, anaplastic large cell lymphoma, and diffuse large B cell lymphoma. Burkitt's lymphoma in this study had clinical presentations similar to those seen in western countries. CONCLUSIONS The distribution of different subtypes of lymphoma in pediatric and adolescent NHL in India differs considerably from that in western countries and other eastern countries.

Abstract
AIMS Polymorphism in genes involved in folate metabolism may influence the susceptibility to acute lymphoblastic leukemia (ALL). The aim of the present study was to determine the role of the two most common polymorphisms of the 5, 10-methylenetetrahydrofolate reductase (MTHFR) gene, MTHFR C677T and A1298C, and their interaction on the susceptibility to ALL. METHODS Seventy-two children with ALL and 109 age- and sex-matched healthy children from Western Iran were screened for MTHFR C677T and A1298C variants by using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). RESULTS The frequencies of MTHFR 677T and 1298C alleles in patients were 29.9% and 43.1%, respectively, that were higher than those in controls (24.8% and 38.1%, respectively). Logistic regression analysis was performed and its result in the odds ratios (ORs) for possession of either MTHFR 677T or 1298C allele was found to be 1.98 [95% confidence interval (CI) 0.72-5.4, p = 0.18] and 1.48 (95% CI 0.59-3.69, p = 0.4), respectively. Also the concomitant presence of both MTHFR 677T and 1298C alleles was not associated with the risk of ALL [OR = 2.12 (95% CI 0.8-5.7, p = 0.13)]. CONCLUSION Our results in a homogenous population with Kurdish ethnic background indicated that neither the MTHFR 677T allele nor the MTHFR 1298C allele is associated with increased risk of ALL.
