Figure 4. Kaplan–Meier metastasis-free survival analysis of TGFβ-EMT signature in fresh frozen samples.
(A) Samples with high TGFβ-EMT signature score (red curve) exhibit significantly worse metastasis-free survival than samples with low TGFβ-EMT signature score (blue curve). (B) Magnitude of the difference in fraction survival between high (red curve) and low (blue curve) groups is similar within the early-stage subset of the cohort. (C) Kaplan–Meier metastasis-free survival analysis of the TGFβ-EMT signature in external fresh frozen Nguyen cohort [29]. Samples with high TGFβ-EMT signature score (red curve) exhibited significantly worse metastasis-free survival, although the magnitude of the difference between high (red curve) and low (blue curve) groups was smaller than in the cohort used for the TMA. (D) Differences in TGFβ-EMT signature score distributions within resected primary colon tumors. Primary tumors from patients with pre-existing metastatic disease at time of surgery (red circles) exhibit higher TGFβ-EMT signature scores than those from patients whose tumors had not metastasized (blue circles).
