To clarify association of epidermal growth factor receptor, human epidermal growth factor receptor 2 with prognosis of colorectal cancer under FOLFOX chemotherapy. A total of 108 colorectal cancer patients under FOLFOX chemotherapy in the hospital from October 2017 to October 2019 were chosen as research subjects. The baseline data of patients were recorded before treatment and levels of serum tumor markers carcino embryonic antigen and carbohydrate antigen 125 and serum epidermal growth factor receptor and human epidermal growth factor receptor 2 were measured and recorded. After 6 courses of FOLFOX chemotherapy, prognosis of patients was observed. The effective patients were included in good prognosis group and the remaining ones were included in poor prognosis group. The baseline data and laboratory indicators before treatment were assessed between two groups and association of epidermal growth factor receptor and human epidermal growth factor receptor 2 with prognosis of colorectal cancer under FOLFOX chemotherapy was evaluated. Among 108 colorectal cancer patients completing FOLFOX chemotherapy, 18 (16.67 %) had complete response, 29 (26.85 %) had partial response, 37 (34.26 %) had stable disease and 24 (22.22 %) had progressive disease and 56.48 % (61/108) had poor prognosis. Carcino embryonic antigen, carbohydrate antigen 125, epidermal growth factor receptor and human epidermal growth factor receptor 2 in poor prognosis group presented elevation relative to those in good prognosis group, with statistical significance (p<0.05). Logistic regression analysis demonstrated that carcino embryonic antigen, carbohydrate antigen 125, epidermal growth factor receptor and human epidermal growth factor receptor 2 had association with prognosis of colorectal cancer under FOLFOX chemotherapy (odds ratio >1, p<0.05). The receiver operating curve demonstrated that area under curve of serum epidermal growth factor receptor and human epidermal growth factor receptor 2 levels before treatment alone and in combination to predict prognosis of colorectal cancer under FOLFOX chemotherapy were 0.709, 0.766 and 0.828, respectively, all of which had certain predictive value. The up regulation of serum epidermal growth factor receptor and human epidermal growth factor receptor 2 may be a risk factor for unfavourable prognosis of colorectal cancer under FOLFOX chemotherapy, which can be used for predicting prognosis of colorectal cancer under FOLFOX chemotherapy.
