Heatmap of gene mutations in patients with double or triple primary lung cancers. These maps visualize the gene mutations present in each cancer. Two or three tumors in each patient were characterized by different mutation profiles, and all patients were diagnosed with having multicentric primary cancers. The remaining case (case 2 in Tables 1 and 2) not illustrated in this figure is described in detail in the Case Presentations section and in Figure 4. ca., cancer.
