CCAR2 and neoplasm: In reproductive system cancers, the relationship between DBC1 overexpression and tumor size yielded inconsistent results, a meta-analysis of two studies suggested that DBC1 overexpression was associated with smaller tumor size (n = 2, RR = 0.616, 95%CI: [0.409-0.928], P = 0.020, I2 = 0.0).
