The survival analyses for the c-kit expression have been demonstrated in several malignant tumours (Tonary et al, 2000; Bar-Sela et al, 2003; Scobie et al, 2003; Krams et al, 2004; Simon et al, 2004; Pan et al, 2005), while there was only one survival analysis (Simon et al, 2004) regarding breast cancer, in which no difference was found in the survival between the patients with or without the c-kit expression. Here, KIT is linked to cancer.
