Figure Lengend Snippet: Worse prognosis of non-responders in arm Cam+TPF (A) Spatial heatmaps showing expression intensity of EGFR , including Cam+TPF-pNR group ( n = 2) and Cam-pNR group ( n = 2); scale bar, 5 mm. (B) Dot plot showing expression levels of genes related to EGFR signaling pathway, including Cam+TPF-pNR group ( n = 2) and Cam-pNR group ( n = 2). (C) Heatmap showing the quantitative immunohistochemical results of post-therapy EGFR and downstream proteins in non-responders in arm Cam+TPF compared with arm Cam, including Cam+TPF-pNR group ( n = 2) and Cam-pNR group ( n = 7). (D) Follow-up of the two non-responders in arm Cam+TPF. Red circle indicates primary tumor, red arrow indicates tumor metastasis. EGFR, epidermal growth factor receptor; CT, computed tomography; MRI, magnetic resonance imaging; PET-CT, positron emission tomography and computed tomography.
