Figure 3. (A) Through Kaplan-meier analysis, patients received simultaneous liver resection (SLR) had statistically longer duration of PFS than patients received no SLR. Value of SMI were recorded in addition to therapeutic response. CRLM patients in the status of PR showed a larger SMI compared to SD and PD (B). Furthermore, fish exact tests were performed in SLR (C) cohort patients and N-SLR (D) cohort patients, respectively. PFS, progression free survival; CRLM, colorectal cancer liver metastasis; PR, partial response; SD, stable disease; PD, progressive disease.
