Correlations of pri-Let-7 gene polymorphisms with the recurrence and metastasis of primary liver cancer after transcatheter arterial chemoembolization

Our findings provide evidence that patients with PLC that carry the AC + CC genotype of pri-let-7a-2 rs629367 after TACE have a worse prognosis than those who carry the AA genotype. We speculate that the pri-let-7 rs629367 SNP could be used as a predictor of recurrence and metastasis after TACE for patients with PLC.
