Kaplan–Meier curves constructed to determine the effect of 8q22 gain on survival revealed significantly (p < 0.05) lower metastasis- and cancer-free survival in breast cancer patients with high 8q22 gain compared with low 8q22 gain, further validating the importance of AEG-1 expression in breast cancer prognosis [52]. The gene discussed is MTDH; the disease is breast carcinoma.
