Abstract
In this study, our aim was to investigate the epidermal growth factor (EGF) and epidermal growth factor receptor (EGFR) gene polymorphisms in oral squamous cell carcinoma (OSCC) patients and non-OSCC healthy controls. This case-control study comprised 89 OSCC and 107 healthy controls by using polymerase chain reaction (PCR) and restriction fragment length polymorphism methods, the genotypes for EGF + 61 A > G (rs4444903) and EGFR R497K (rs2227983) were analyzed. According to the EGF + 61 A > G genotype distribution, individuals with the GG genotype were more prevalent in the OSCC group when compared to the healthy controls. But the AA genotype frequency was significantly higher in the healthy control group. The frequency of G allele carriers was 2.3 times higher than A allele carriers in OSCC patients (p < .001). For the EGFR R497K genotype, there was no significant difference between the OSCC and healthy control groups. Regarding the study results, the G allele of EGF + 61 A > G polymorphism was associated with OSCC. Larger populations and functional investigations should be used to explore the nature of the interaction between EGF and OSCC.

Wang J, Zhong Y, Meng G. EGF rs4444903 polymorphism is associated with risk of HCV-related cirrhosis and HBV/HCV-related hepatocellular carcinoma. Int J Clin Oncol 2021; 26:2053-2064. [PMID: 34291370 DOI: 10.1007/s10147-021-01994-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2021] [Accepted: 07/14/2021] [Indexed: 01/27/2023]
Abstract
OBJECTIVE The epidermal growth factor (EGF) rs4444903 polymorphism is associated with aberrant expression of EGF, which was a characteristic of cirrhotic liver diseases, induces highly malignant hepatocellular carcinoma (HCC). Numerous studies have uncovered the association of this polymorphism with the risk of liver disease, but with inconsistent findings. MATERIALS AND METHODS Therefore, this meta-analysis was performed to evaluate whether EGF rs4444903 polymorphism conferred susceptibility to liver disease. Totally 18 eligible articles were identified by searching PubMed, Google, CNKI and EMBASE up to December 1, 2020. RESULTS Our results indicated that there was no significant difference in the minor G allele frequency of rs4444903 polymorphism between HBV/HCV carriers and healthy controls. In other words, EGF rs4444903 polymorphism was not associated with the risk of HBV/HCV. Interestingly, this polymorphism increased the risk of liver cirrhosis in the controls with HCV infection. Additionally, EGF rs4444903 polymorphism is associated with the increased risk of HCC under the five models. Subgroup analysis by ethnicity shows that rs4444903 polymorphism intensifies the risk of HCC among Asians and Caucasians. Strong correlation is also reported in controls with cirrhosis or HCV infection and studies using PCR-RFLP genotyping. CONCLUSIONS The study supports that EGF rs4444903 polymorphism is a genetic contributor to liver cirrhosis and HCC in the overall population. Nevertheless, this conclusion must be confirmed by larger studies with more diverse ethnic populations.

EGF+61 A>G polymorphism does not predict response to first-generation EGFR tyrosine kinase inhibitors in lung cancer patients. Thorac Cancer 2020; 11:2987-2992. [PMID: 32881389 PMCID: PMC7529554 DOI: 10.1111/1759-7714.13628] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2020] [Revised: 07/31/2020] [Accepted: 07/31/2020] [Indexed: 11/30/2022] Open
Abstract
Epidermal growth factor (EGF) and its receptor (EGFR) play a paramount role in lung carcinogenesis. The polymorphism in the EGF promoter region EGF+61A>G (rs4444903) has been associated with cancer susceptibility, but its role in lung cancer patients treated with tyrosine kinase inhibitors (TKIs) remains unknown. Here, we aimed to evaluate the predictive and prognostic role of EGF+61A>G SNP in lung cancer from Brazilian EGFR-mutated TKI-treated patients. Herein, patients carrying EGFR-sensitizing mutations submitted to TKI treatment (gefitinib/erlotinib) were analyzed (n = 111) for EGF+61A>G genotype by TaqMan genotyping assay. TKI treatment was classified as partial response (PR), stable disease (SD), and disease progression (DP), according to RECIST1.1. Association analysis was assessed by chi-square and Fisher's test (univariate) and multinomial model (multivariate) and survival analysis by Kaplan-Meier method and log-rank test. The EGF+61A>G genotype frequencies observed were: AA = 31.5% (n = 35), AG = 49.6% (n = 55) and GG = 18.9% (n = 21). The allelic frequencies were 56.3% for A, and 43.7% for G and the population was in Hardy-Weinberg equilibrium (P = 0.94). EGF+61A>G codominant model (AA vs. AG vs. GG) was associated with a response to TKIs (P = 0.046), as well as a recessive model (AA vs. AG + GG; P = 0.023). The multinomial regression showed an association between the codominant model (AG) and recessive model (AG + GG) with SD compared with DP (P = 0.01;OR = 0.08; 95% CI = 0.01-0.60 and P = 0.02;OR = 0.12; 95% CI = 0.20-0.72, respectively). No association between genotypes and progression-free or overall survival was observed. In conclusion, the EGF+61 polymorphism (AG and AG + GG) was independently associated with stable disease in lung cancer patients although it was not associated with the overall response rate to first-generation TKIs or patient outcome.

Abstract
To explore the association between epidermal growth factor (EGF) 61A/G polymorphism and lung cancer.All eligible case-control studies published up to August, 2019 were identified by searching PubMed, The excerpta medica database, China Academic Journals Full-text Database, China Biology Medicine, China National Knowledge Infrastructure, China Science and Technology Journal Database, and Wanfang databases. Two researchers independently identified the literature, extracted data, and evaluated quality according to inclusion and exclusion criteria. Meta-analysis was performed by Stata 15.0.A total of 6 studies is included, including 1487 cases and 2044 control subjects. Compared with allele A, allele G was considered to have no association with the risk of lung cancer, odds ratio = 1.07 (95% confidence interval: 0.98-1.15). GG recessive genotype, GG + GA dominant genotype, GG homozygote genotype and GA heterozygote genotype were found out that all of them are not associated with the risk of lung cancer. No association between EGF 61A/G polymorphism and lung cancer was found out by ethnical subgroup analysis. However, in view of the limitations of this study, such as the results of quantitative and sensitivity analysis may be lack of accuracy, so the conclusions of allele model and recessive gene model should be made carefully.It suggested that there was no association between polymorphism of EGF 61A/G and susceptibility of lung cancer.
