Next, the Kaplan–Meier analysis results showed that increased intratumoral stain intensity of PD-1+/CD8+/Rab37+ and PD-1+/TIM3+/CD8+/Rab37+ T cells correlated with poorer overall survival and disease-free survival of lung cancer patients (Fig. 5G–J). This evidence concerns the gene RAB37 and lung carcinoma.
