No statistically significant differences were found between ALK-rearranged and ALK wildtype tumors with respect to clinical stage (except for stage III, p = 0.038), T stage (except for T1b, p = 0.025), N stage (except for N2, p = 0.003), M stage (except for M1b, p = 0.013), tumor location (except for the right upper lobe, p = 0.001, and the middle lobe, p = 0.019), mean tumor size and mean patient age (Table 8). This evidence concerns the gene ALK and neoplasm.
