Abstract:
Objective To explore the clinical effect and safety of cetuximab plus mFOLFOX6 first-line treatment in k-ras wild type patients with liver metastasis from colorectal cancer.Methods 40 k-ras wild-type colorectal cancer patients with liver metastasis diagnosed by histological detection in our hospital were chosen.20 patients in the observation group were treated with cetuximab plus mFOLFOX6.20 patients in the control group were only given mFOLFOX6.To observe the effect and safety of the two groups.Results RR,operation excision rate and R0 removal rate of observation group (60％,45％,35％) were significantly higher than those of the control group (30％,15％,10％),the differences were statistically significant (x2 =3.95,4.36,4.28,P ＜ 0.05);The PFS of the observation group (16.37 ± 7.24) was higher than (11.52 ± 6.85) in the control group,but the difference was not statistically significant (P ＞ 0.05).In the observation group,there were 2 cases with rash,2 cases of leukopenia,1 case with nausea and vomiting,the incidence rate of adverse reaction was 25 ％ (5/20) ;In the control group,there were 2cases with leukopenia,1 case with nausea and vomiting,there was no rash and paronychia,the incidence rate of adverse reaction was 15％ (3/20),there was no significant difference in incidence rate of adverse reaction between the two groups (P ＞ 0.05).Conclusion Cetuximab combined with FOLFOX6 can improve the performance clinical remission rate and lesion resection rate of k-ras wild type patients with liver metastases from colorectal cancer,and has high safety,which is worthy of clinical application.
