Abstract

Graphic abstract

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.
