However, there were significant associations between LAPTM4B levels and classic variables including age (p = 0.020), histological type (invasive ductal carcinoma, IDC) (p = 0.021), TNM stage (p = 0.001), nodal metastasis (p < 0.001), distant metastasis (p = 0.001), and Ki-67 status (p = 0.034). The gene discussed is MKI67; the disease is invasive ductal breast carcinoma.
