Next to PTTG-1 status, other clinical parameters such as performance status (WHO 0/I vs. II/III; p= 0.0007), tumor stage (I/II vs. III/IV; p = 0.0117) and LDH level (serum levels ≤ 240 units/l vs. > 240 units/l; p = 0.0246) were also related to survival time using Kaplan-Meier analysis. The gene discussed is PTTG1; the disease is neoplasm.
