We found shorter survival for the group without YY1 amplification expression without LOH for hDMP1 (p = 0.0109, χ2 = 11.1565 for PFS, p = 0.0024, χ2 = 14.4367 for TS; Figure 4C,D), indicating that YY1 amplification (-); hDMP1 LOH (-) genotype is an ominous sign of NSCLC. The gene discussed is YY1; the disease is non-small cell lung carcinoma.
