Fig. 4. Inferred phylogeny and migration patterns of metastatic gastric cancer with genomic similarity and the resulting prognosis.

Fig. 4

a Conceptual figures depicting two distinctive metastatic progression patterns, branched and diaspora. Clinical course and phylogenetic tree (by MEDICC2) of a representative case of (b) branched progression (GCM04) and (c) diaspora progression (GCM10). d, e Heatmap of pairwise Jaccard indices, representing genomic similarity between tumors from an individual, in each representative case of branched (GCM04) and diaspora (GCM10) progression. f Statistical comparison of the average Jaccard index between patients with branched versus diaspora progression. Diaspora progression showed a lower Jaccard index, implying more genetic inter-tumoral heterogeneity when compared to branched progression (**; p < 0.005). Kaplan–Meier’s curves for overall survival (OS) based on (g) metastatic migration patterns and migration patterns with the molecular subtypes of (h) primary tumor and (i) metastatic tumors. The diaspora progression was related to poor prognosis when compared to branched progression (P = 0.0031). When considering the molecular subtypes of primary or metastatic tumors together, both the migration pattern and subtype of the metastatic tumors were found to be related to the patients’ survival (p = 0.0017, i). P primary tumor, LN lymph node, Lu lung metastasis, R recurrence, A alive, Li liver metastasis, E expired.
