LAMP1 and cancer: Through analysis, we observed a significant association between lower LAMP1 expression in cancer tissues (P=0.038; Table 3; Figure 5A) and higher T stage (P<0.001; Table 3; Figure 5B), M stages (P=0.003; Table 3; Figure 5C), clinical stages (P<0.001; Table 3; Figure 5D) as well as histologic grade (P=0.019; Table 3; Figure 5E).
