High levels of Oct4, M-CSF, and CD206 expression are correlated with tumor recurrence in patients with stages IB, IIB, and IIIA lung cancer. a Immunoreactivity of Oct4, M-CSF, and CD206 was categorized as low and high in tumor samples of patients with lung cancer. b and c Kaplan-Meier curves of recurrence-free rate in patients with high or low expression of CD206 (b), as well as with combinations of different levels of Oct4, M-CSF, and CD206 expression (c). Differences in recurrence-free intervals were analyzed by the log-rank test. Scale bar, 50 μm
