As for FA catabolic enzymes (table 3), in stage I, III, and IV ccRCC patients, we found that CPT1A (HR 95% CI=0.35 (0.17-0.72), 0.54 (0.30-0.96), 0.49 (0.28-0.87), respectively), ACAT1 (HR 95% CI=0.50 (0.28-0.91), 0.52 (0.30-0.92), 0.45 (0.28-0.74), respectively) mRNA expressions were associated with favorable OS. This evidence concerns the gene ACAT1 and nonpapillary renal cell carcinoma.
