PLP2 Expression as a Prognostic and Therapeutic Indicator in High-Risk Multiple Myeloma

Table 4

PLP2 was related to treatment response. The correlations between drug responses with PLP2 levels were analyzed by chi-square test. Patients with low PLP2 expression significantly responded to chemotherapies evidenced by increased ORR, ≥VGPR, ≥CR, and ≥sCR.
