Heatmap of gene mutations in patients with metastatic lung cancers. The mutation profiles were consistent between the individual tumors in each case and the tumors were identified as intrapulmonary metastasis. Case 33 was synchronous cancers, while the other cases in this figure were metachronous cancers. The remaining 2 cases of metastatic lung cancers (cases 10 and 30 in Table 1 and Table S2) that are not shown in this figure are described in detail in the Case presentation section. r, right; S, segment; AF, allele fraction.
