Event-free survival and overall survival of patients with newly diagnosed MM according to HPSE expression in the WBM and MMCs. (A) Expression of HPSE in the WBM of 30 patients with newly diagnosed MM (left) and Kaplan-Meier survival curves for patients with MM with the highest (HPSE^high; n = 15) or the lowest (HPSE^low; n = 15) HPSE expression in the WBM (right). (B) Expression of HPSE in the purified MMCs from 30 patients with newly diagnosed MM and Kaplan-Meier survival curves for patients with MM with the highest (n = 15) or the lowest (n = 15) HPSE expression in the MMCs. Open and filled bars indicate that the Affymetrix cell is absent or present, respectively.
