Figure 3. LIFr expression is significantly correlated with 5-year survival of all melanoma patients and primary melanoma patients.

Patients with strong LIFr expression have a significantly worse overall a, c. and disease specific 5-year survival b, d. than those with weak staining in all melanoma patients (including primary and metastatic melanoma) and primary melanoma patients (P = 0.000 and 0.000 respectively, log-rank test). However LIFr expression did not show any correlation to the survival rate of metastatic melanoma patients e, f. (P = 0.140 and 0.102 respectively, log-rank test).
