The purposes of the current study were conducted to explore the relationships among long non-coding RNA gene H19 (LncRNA H19) polymorphisms and clinicopathological characteristics of uterine cervical cancer, and patient prognosis in Taiwan. Five genetic variants of LncRNA H19 rs3024270, rs2839698, rs3741219, rs2107425 and rs217727 were recruited from one hundred and thirty-four patients with invasive cancer, 101 with high-grade cervical intraepithelial neoplasia (CIN) of uterine cervix and 325 controls and their genetic distributions were determined. It indicated no associations of these LncRNA H19 genetic variants with development of cervical cancer. CC/CT in LncRNA H19 rs2839698 exhibited less risk to have pelvic lymph node metastasis [Odds ratio (OR): 0.19, 95% Confidence interval (CI):0.04-0.82, p=0.028)], as compared with TT. Meanwhile, cervical cancer patients with AA/AG in rs3741219 also had less risk to develop pelvic lymph node metastasis (OR: 0.17, 95% CI: 0.05-0.63, p=0.008), large tumor (OR: 0.17, 95% CI: 0.04-0.82, p=0.014) as well as parametrium (OR: 0.26, 95% CI: 0.07-0.95, p=0.045) and vagina invasion (OR: 0.25, 95% CI: 0.07-0.91, p=0.041, as compared to those with GG. However, only positive pelvic lymph node metastasis was related to worse recurrence-free survival and poor overall survival. Conclusively, it indicated no association of LncRNA H19 SNPs with cervical carcinogensis in Taiwanese women. Although genotypes TT in LncRNA H19 rs2839698 and GG in rs3741219 are related to some poor clinicopathological parameters of cervical cancer, only pelvic lymph node status could predict 5 year patient survival significantly.
The association of intercellular adhesion molecule 1 (ICAM-1) genetic polymorphisms with uterine cervical carcinogenesis has seldom been reported. Therefore, the aim of this study was to investigate the association of single-nucleotide polymorphisms (SNPs) and haplotypes of ICAM-1 with cervical tumorigenesis in Taiwanese women. Four hundred forty four women, including 91 with cervical invasive cancer, 63 with precancerous lesions, and 290 normal controls, were recruited. The genotypic distribution of 4 SNPs of ICAM-1, rs5498 (A1548G), rs5491 (K56M), rs281432 (C8823G), and rs3093030 (C-286T) was determined using real-time polymerase chain reactions and genotyping. Compared to homozygous wild CC, heterozygous CG, homozygous mutant GG, or genotypes with CG/GG display increased risks or a tendency of precancerous lesions or invasive cancer with strong power in rs281432. The homozygotic mutant alleles TT in rs3093030 and homozygotic mutant alleles GG in rs5498 were associated with a higher risk of invasive cancer and precancerous lesions, respectively, but with lower power. The CG/TA/TG haplotypes of ICAM-1 SNPs rs3093030 and rs5498 exhibited a tendency to increase susceptibility to precancerous lesions and invasive cancer. In conclusion, Taiwanese women with ICAM-1 SNP rs281432 and haplotypes CG/TA/TG of rs3093030 and rs5498 are associated with uterine cervical carcinogenesis.
The objectives of this study were to define the associations among single nucleotide polymorphisms (SNPs) of metastasis-associated in colon cancer-1 (MACC1) gene, development and clinicopathological characteristics of uterine cervical cancer, and patient survival in Taiwan. Genotypic frequencies of 5 MACC1 SNPs rs975263, rs3095007, rs4721888, rs3735615 and rs1990172 were identified for 132 patients with invasive cancer, 99 with high-grade cervical intraepithelial neoplasia and 338 normal controls using real-time polymerase chain reaction. It revealed that there were no associations of these MACC1 SNPs with cervical carcinogenesis. In the meantime, cervical cancer patients with genotype GG in MACC1 SNP rs975263 tended to display more risk to have vaginal invasion than those with AA/AG (p=0.042, OR: 8.70, 95% CI: 0.81-433.22). In multivariate analysis, positive pelvic lymph node metastasis could significantly predict worse 5 years survival rate (p=0.001; HR=9.98, 95% CI=2.64-37.77) for cervical cancer patients. In conclusion, pelvic lymph node status rather than MACC1 SNPs was the only independent parameter that could significantly predict 5 years survival rate in Taiwanese women with cervical cancer.
Genetic variants of long noncoding RNA metastasis-associated lung adenocarcinoma transcript 1 (lncRNA MALAT1) have been reported to be associated with several cancers. Until now, no study reveals the associations between lncRNA MALAT1 polymorphisms and cervical cancer (CC). The objectives of this study were to explore the correlations among MALAT1 polymorphisms and occurrence and clinicopathological parameters of CC, as well as patient 5 years survival in Taiwanese women. The study recruited 116 patients with cervical invasive cancer and 89 patients with cervical precancerous lesions, as well as 268 non-cancer control women. LncRNA MALAT1 polymorphisms rs3200401, rs619586 and rs1194338 were selected and their genotypic frequencies were defined by real-time polymerase chain reaction. Our results revealed that there are no relationships between lncRNA MALAT1 genetic variants and occurrence of CC. The independent factor among lncRNA MALAT1 genetic variants and clinicopathological parameters were positive pelvic lymph node metastasis (p=0.001, HR: 10.94, 95% CI: 2.65-45.23). In conclusions, lncRNA MALAT1 genetic variants are not related to occurrence and clinicopathological characteristics of CC and patient 5 years survival in Taiwanese women. Pelvic lymph node metastasis could independently predict the patient 5 years survival among various MALAT1 polymorphisms and clinicopathological factors in CC.
Prenatal diagnosis of cervical teratoma is very crucial, allowing early detection of masses that obstruct the airway. Therefore, a multidisciplinary examination and follow-up are recommended for early prenatal diagnosis.
