Figure 4. CRLM Patients with gain or loss of SMI was distributed in 3 months (A), 6 months (C) and 12 months’ (E) post-operation. Accordingly, prognostic value of loss of SMI with different post operative CT scan was determined. Patients with different SMI status from 3 months’ (B) scan haven’t demonstrated any survival difference (P=0.061), while patients with different SMI status 6 months’ (D) and 12 months’ (F) SMI results had different survival outcome (P-value<0.001). CRLM, colorectal cancer liver metastasis; SMI, skeletal muscle index; CT, computed tomography.
