HOTAIR rs920778 polymorphism is associated with ovarian cancer susceptibility and poor prognosis in a Chinese population

Aim: The aim of this study was to determine if HOTAIR rs920778 polymorphism is associated with ovarian cancer susceptibility and prognosis. Materials & methods: The data were obtained from two independent groups including 329 ovarian cancer patients and 680 cancer-free, age-matched women. Blood samples were collected and genomic DNA was extracted for genotyping. Results: TT genotype and T allele of HOTAIR rs920778 were significantly associated with a decreased ovarian cancer risk (p = 0.0004 and p < 0.0001, respectively), which associated with advanced tumor stage, lymph node metastasis and poor prognosis. Moreover, TT and TC carriers obtained a much shorter survival (p = 0.026). Conclusion: These findings propose that HOTAIR rs920778 polymorphism influences ovarian cancer susceptibility and prognosis, and further studies are warranted in other populations.
