AFP and granular cell tumor: (70) quantified miRNA levels by quantitative real-time polymerase chain reaction and found that the levels of miR-302a-3p, 371a-3p, 372-3p and 373-3p were significantly increased in GCT patients, and these mRNAs together outperform HCG and AFP testing in terms of sensitivity (84.7%) and specificity (99%).
